Asus Chromebook C200 review: Long battery life helps this $249 model stand out

Asus Chromebook C200 $249.00 The Asus Chromebook C200 has a few advantages compared to other 11-inch models: A battery that lasted over eight hours in our stringent tests, and a pending update for 802.11ac Wi-Fi. In most other ways,...

The $249 Asus Chromebook C200 is helping me make peace with 11-inch Chromebooks. I understand they’re very affordable. I understand they’re easy to tote around the house or the schoolyard. I even understand that they're acceptable for basic browsing activities.

But the Asus Chromebook C200 also manages to be not quite as disappointing as some other low-end models I’ve tried. Its battery life is nice and long, too. In this compromise-ridden price range, the Chromebook C200 is one of the few decent choices.

The Asus Chromebook C200 has a matte-black lid that quickly becomes smudged with fingerprints.

The Chromebook C200 does have its shortcomings. Some of the things are little, like the ease with which the matte-black lid and even the textured-black bottom seems to pick up fingerprints (and I'm not munching potato chips or otherwise being extra-schmutzy). It has the hard-plastic keys that are sadly typical of many Chromebooks, though the travel seems less jarring than what I’ve experienced with other low-end models.

Some of its other shortcomings are more fundamental. The 11.6-inch LED-backlit display, with the usual 1366x768 resolution, has a shiny surface that picks up tons of reflection. The image quality and viewing angles are nothing special, either, and it's not a touchscreen. There's a 720p webcam over the display.

The island-style keyboard on the Asus Chromebook C200 well laid out, but the hard plastic keys are tough to type on. 

Performance also disappointed us: The 2.42GHz Intel Bay Trail-M N2830 processor posted a wan Peacekeeper score of 1511, only a little better than HP’s Chromebook 11, which uses an Exynos ARM processor.

Some things about the C200 are just plain normal. It has 2GB of memory and 16GB of on-board storage. You get one USB 2.0 port and one USB 3.0 port, plus an HDMI port and an SD card slot. You even get a Kensington lock port. Asus also touts the larger size of its trackpad, though it wasn't a highlight for me.

You'll find a single USB 2.0 port and a Kensington lock port on the right side of the Asus Chromebook C200.

The speaker grille, nestled underneath the wide hinge, is wider than usual—some low-end laptops have ridiculously small speaker openings. Laptop speakers rarely deliver good sound, but the Chromebook C200's seemed to achieve a slightly better stereo effect. The volume range and sound quality were also slightly better than usual.

One thing is ready for the future: The Wi-Fi. The Chromebook C200 comes with an onboard 802.11ac Wi-Fi adapter, but it's currently limited to operating in 802.11a/b/g/n mode. At the time of this review's posting, Asus said Google was still working on a firmware update that will activate its 802.11ac functionality.

Ports on the left side of the Asus Chromebook C200 include headphone/mic, SD, USB 3.0, and HDMI 1.4, plus power.

Here’s the brightest spot with the Chromebook C200: battery life. According to Asus, the C200's 48-Watt-hour, 3-cell lithium-ion battery can support continuous video playback for up to 11 hours. Our benchmark is pretty tough, but the Chromebook C200 faced adversity with a smile, lasting 8 hours and 26 minutes on a full charge. This is a Chromebook you can use for a good, long stretch even if you ditch the AC adapter, and that could be all it needs to compete with other models in this price range—most of which have lasted closer to 4 to 6 hours in our tests.

I’ve found few low-end Chromebooks worth recommending, but the Chromebook C200 is one—mostly it’s for the battery life, but in various other ways, Asus has also managed to make this a noticeably better choice than others I’ve tried. It's a bargain with few regrets and one big, long-lasting bonus in the battery.

Acer Aspire M5 review: A big display, terrific battery life, and a moderate price tag

Acer Aspire M (model M5-583P-6428) $700.00 Fans of large laptop touchscreens will appreciate the Aspire M’s roomy display, slim profile, and excellent battery life. The price-to-performance isn't bad either.

Despite being just 0.7 inch thick, Acer’s Aspire M5 (model M5-583P-6428) weighs a hefty 4.9 pounds. So it’s fortunate for Acer that Intel’s Ultrabook definition includes only a height limit: 0.9 inch. More important, the Aspire M delivers a big display, great battery life, and good performance for a moderate $700.

Outfitted with an Intel Core i5-4200U (one of the lower-end entries in Intel’s current Haswell lineup of mobile CPUs), a generous 8GB of DDR3/1600 RAM, Intel’s integrated HD4400 graphics, and a 500GB hard disk that spins its platters at 5400 rpm, the Aspire M scored a respectable Notebook WorldBench 8.1 score of 143. That’s almost 50 percent better than our reference unit, the Asus VivoBook S550CA, but we’ve seen a few laptops in this price range perform even higher.

Acer's Aspire M performed well on our benchmarks, but it's not a barn-burner.

It’s easy to see where the Aspire M falls behind in performance: With any tasks involving storage retrieval, its slow hard drive can’t compete against solid-state drives (or SSD caches), which are becoming increasingly common. But its Haswell architecture clearly helped Acer's machine hold its own in tasks involving number crunching (image editing, for example), and contributed to its impressive battery life of more than 7 hours. That’s one of the best running times we’ve seen from any laptop this year.

ROBERT CARDINThe 15.6-inch display allowed Acer to fit a full-size keyboard, including a numeric keypad, into the Aspire M's chassis.

The Aspire M's design makes a good first impression, with its pewter-colored brushed metal lid and black soft-touch underbelly. The plastic interior matches the color of the lid, contrasting nicely with the black island-style keyboard—a standard-size backlit model that includes a numeric keypad. But good luck landing on the correct key if you’re a touch typist: They’re flat and slippery, and it can be difficult to find keys that are normally on or near the right edge (backspace and delete, for example). A little sculpting on the keys and perhaps some extra spacing between the standard keyboard and the keypad would have helped.

The touch controls—a multitouch touchpad (with mechanical corners for right and left mouse clicks) and the Aspire M's 10-point touchscreen display are responsive and fun to use. The display itself is bright and pleasing; still, I was a bit surprised by Acer’s decision to go with a resolution of only 1366 by 768 pixels on its 15.6-inch screen. Acer didn’t include an optical drive, but when you’re streaming video, 1080p resolution looks so much better—especially when you’re up close to the screen. The Aspire M’s audio subsystem, on the other hand, is very good, thanks to a strong amplifier, four bottom-mounted speakers, and Dolby Home Theater.

ROBERT CARDINAlthough the Acer Aspire M is ultraslim, measuring just 0.7 inch thick, it weighs almost 5 pounds.

Connectivity and port options are basic: Two USB 2.0 ports (but just one USB 3.0 port), an SD card slot, headset jack, gigabit ethernet, HDMI, and an Acer Converter Port (for dongles, such as VGA). The Aspire M also supports dual-band 802.11n Wi-Fi. The built-in high-def webcam was fairly typical, producing decent if not great video in Skype calls.

If you’re looking for a notebook with a large touchscreen and respectable performance, Acer’s Aspire M is a good choice at a price that won’t instill sticker shock. It’s not that easy to find all these attributes in a single product. And Acer has done a good job of balancing price and performance.

Lenovo IdeaPad U430 Touch review: A daily driver with all-day battery life

Lenovo IdeaPad U430 Touch $700.00 This is one of the most affordable Ultrabooks we’ve seen, and the compromises Lenovo made to get there are not showstoppers by any stretch.

If you think an Ultrabook is out of your price range, you haven’t seen Lenovo’s IdeaPad U430 Touch. Ostensibly designed for the consumer market, the U430 carries over many of the features that render Lenovo’s corporate laptops so appealing, including a rigid but elegant all-aluminum enclosure and an exceptionally good, island-style, backlit keyboard.

The dual-core Intel Core i5-4200U processor inside the IdeaPad U430 Touch is one of the least powerful members of the Haswell Core i5 family, but that didn’t stop this computer from delivering a Notebook WorldBench 8.1 score of 199. That marks it as nearly twice as fast as our reference notebook, an Asus VivoBook S550CA powered by a third-generation Intel Core i5-3317u. Lenovo outfits the U430 with a typical 4GB of DDR3/1600 memory.

Haswell notebook Worldbench performanceLenovo’s IdeaPad U430 Touch is nearly twice as powerful as our reference notebook.

Lenovo clearly had to hold back on some features to hit the $700 price, and the 14-inch display is one of them. The touchscreen panel is plenty bright, and it delivers very good image quality, but its resolution is limited to 1600 by 900 pixels. Still, that’s better than the 1366-by-768-pixel resolution that many of its competitors offer. Another drawback is that this computer relies on the GPU integrated into its Core i5 CPU, so you can’t expect to do much hard-core gaming: Among the five laptops in our testing group, the U430 posted the slowest performance on BioShock Infinite, even with the resolution reduced to 1024 by 768 pixels and the visual quality set to low.

Haswell notebook Bioshock performanceIntel's integrated graphics processors are much better than the GPUs in its third-generation Core processors, but you'll still need more power than that if you want to play games.

The U430 is equipped with a 500GB mechanical hard drive that spins its platters at a leisurely 5400 rpm. A solid-state drive—or at least an SSD cache—would have produced much better performance, but Lenovo would have had a hard time reaching such a low price with either of those features. You’ll find two USB 2.0 ports on the right side of the computer, along with an SD Card reader and the power connector.

Haswell notebook battery life performanceBattery life of 6 hours, 38 minutes is an impressive stat.

Lenovo placed the sole USB 3.0 port on the left side, along with a headset jack, an HDMI output, and a wired gigabit ethernet port. Wireless networking and Bluetooth come courtesy of Intel’s dual-band Wireless-N 7260 chipset (which also supports Intel’s WiDi wireless video-streaming technology). Stereo speakers on the bottom of the chassis deliver surprisingly clear highs, but they’re almost devoid of bass response.

The Lenovo IdeaPad U430 Touch is on the heavy side for an Ultrabook, weighing in at 4.2 pounds, but it’s well made and very attractive, and its battery lasted for a full 6 hours, 38 minutes in our tests. It’s a terrific value at $700.

Note: This review is part of a roundup of the 5 best Haswell notebooks as of September 2013.

Dell Latitude 3330 review: A budget laptop with great battery life but lousy performance

Dell Latitude 3330 $561.00 Sleek and lightweight, the budget-priced Dell Latitude 3330 makes a good first impression. But it has difficulty running even the most routine multimedia—much less games—because of its bare-bones...

If someone tells you “Dude! You’re gettin’ a Dell!” in reference to the Latitude 3330, run away. Dell makes plenty of good computers, but this isn’t one of them.

Admittedly, the Latitude 3330 didn’t burst into flames or poke anyone’s eye out during our testing. But you have many better choices in the same price range. Though one of the five budget notebooks in this roundup (HP’s Pavilion TouchSmart 11z-e000) delivered even lower performance than this one—probably because it has an even less powerful CPU than the Dell’s 1.5GHz Intel Core i3-2375m—the HP also costs $110 less than the Latitude 3330 and has a ten-point touchscreen. The Dell’s 13.3-inch, 1366-by-768-pixel display doesn’t support touch, though its trackpad does support simple gestures such as two-finger scrolling.

ROBERT CARDINDell’s Latitude 3330 doesn't deliver the performance its price tag warrants.

The Latitude has only 4GB of DDR/1600 memory, but an open and readily accessible slot accommodates a second module to double its memory. Its puny 320GB, 5400-rpm hard drive is similarly easy to access and upgrade. And this is one of only two notebooks in our roundup to include a removable and upgradable battery (the other one again being the HP Pavilion).

One component that won’t be easy to swap out is the Dell Wireless 1504 single-band (2.4GHz), 1x1, 802.11n Wi-Fi adapter, which delivers a physical link rate of just 150 megabits per second. The laptop doesn’t provide Bluetooth support, either. But it does have a gigabit ethernet interface.

Unlike most of the notebooks in this price range, the Latitude 3330’s chassis contains some aluminum elements that render it considerably more rigid than the other machines we looked at. The lid, on the other hand, is rather flimsy, and the display inside doesn’t feature edge-to-edge glass, as most of the others do.

Best laptop for college: PCMark7The PCMark 7 Productivity element of our benchmark suite evaluates a system's performance with everyday office tasks.

The Latitude 3330’s display isn’t wide enough to accommodate a deck with both a full-size keyboard and a numeric keypad, but the system’s arrow keys are full-size and not easily mistaken for anything else. Apart from not being backlit, the island-style keyboard is well designed and a joy to type on, delivering firm but springy tactile feedback. The Function keys in the top row play their traditional roles, so you’ll need to hold down the Fn key and tap them to access their alternative assignments, such as controlling a media player.

Benchmark performance

The Latitude 3330 tied for dead last in our Notebook WorldBench 8.1 benchmark. Its overall score of 64 was more than 35 percent slower than our reference Asus VivoBook S550CA. Drilling down into some of the individual benchmarks from that suite, I note that the Dell finished next to last in the PCMark7 Productivity benchmark and the BioShock Infinite test, beating out only the HP Pavilion TouchSmart 11z-e000.

Our Notebook WorldBench 8.1 suite includes a broad array of benchmarks for evaluating a notebook's performance.

Connectivity and conclusion

Dell broke the pattern of Intel-powered laptops providing only one USB 3.0 port. The Latitude 330 boasts two, plus one USB 2.0 port that can charge a device whether the computer is awake or asleep. It doesn’t have an optical drive, but its media card reader supports both SD and MMC media.

ROBERT CARDINThe Dell Latitude 3330 is one of the lighter laptops we evaluated.

Dell follows the crowd by providing HDMI and VGA video outputs. Because the Latitude’s Wi-Fi adapter isn’t an Intel model, the system doesn’t support Intel’s WiDi wireless media-streaming. If your primary concern is long battery life, however, be aware that this machine turned in a first-place finish, running for 5 hours, 13 minutes. And you can quickly pull out a run-down battery and snap in a fresh one to double the laptop’s useful life. But that’s one of the system’s few truly bright spots.

We also reviewed this model as a small-business laptop. You can read that review here.

Editor's note: This notebook was reviewed as part of a roundup for back-to-school season. You can read that story, along with reviews of the five notebooks we compared it to, here.

Countdown: 10 Smartphones with the Longest Battery Life

With their 1-GHz (or faster) processors and 4G data speeds, smart phones have never been more powerful–or more power hungry. Yes, specs and apps matter, but what good are they if you’re hunting for an outlet by lunchtime? If you want a smartphone that endures, check out the handsets that made our list. These devices lasted at least 5.45 hours on the LAPTOP Battery Test, which involves continuous web surfing over 3G/4G on 40-percent brightness.

 Click through the below slideshow to see which smartphones truly go the distance.

On the LAPTOP Battery Test, the Maxx lasted an epic 8 hours and 25 minutes. With this kind of staying power, you can expect to use your phone well into the evening without having to recharge. After unplugging the Maxx at 7 a.m. on a Saturday and using it intermittently, it still had 20 percent of a charge left by Sunday at 8 p.m. Unfortunately, the battery is non-removable, so forget about buying a third-party extended battery or carrying a spare.

Best Battery Life: Laptops That Last 7+ Hours

What good is a notebook that dies two hours after it’s unplugged from the wall? Not much. We’ve created a list of the clamshells that ran the distance on the LAPTOP Battery Test (continuous web surfing over Wi-Fi).  Each machine lasts (at least) to the 7-hour marker, but some systems use larger, sold-separately batteries to stay active up to 20 hours. See for your yourself below.

Consider the Lenovo ThinkPad X230 the poster-laptop for systems with optional batteries. The 12-inch ultraportable ships with a 6-cell battery that lasts a decent 7 hours, but the sold-separately 9-cell option pushes the juice supply beyond the 12-hour mark. If that's not enough productivity time for you, the X230 also works with a sheet-battery that, when paired with the 9-cell, helped the system run an epic 20 hours!

Ads on Android Apps Significantly Drain Battery, Research Indicates

It might not be playing Angry Birds that causes your battery life to drop precipitously — it could be the ads that the game serves. According to a recent study by Microsoft and Purdue University, Android apps that feature ads significantly affect your phone’s battery life.

Using an HTC Passion running Android 2.3 “Gingerbread,” the researchers looked at five popular apps — Angry Birds, MapQuest, FreeChess, The New York Times and the Android browser — and measured how much the ads affected each app’s overall battery usage. They found that processes related to advertisements — uploading user statistics, tracking the user’s location with GPS and serving the ad itself — accounted for up to 75 percent of an app’s battery usage.

To conduct the study, the researchers developed a custom app called EProf, which measures both the overall amount of energy that an app uses as well as how much energy specific specific processes consume. Using this tool, the team discovered that in any given app, the processes related to ads drain the most power.

When they tested Angry Birds, for instance, the researchers found that the uploading user data, tracking the user’s location, and downloading advertisements caused 70 percent of the app’s battery drain — only 30 percent of the battery usage was due to the game itself. Similarly, 65-75 percent of FreeChess‘s battery usage was due to ads. The New York Times and the native browser fared better, with only 15 percent of the apps’ battery usage caused by tracking and advertisements.

According to the study, much of this battery drain is unnecessary — poor coding of the ad modules results in inefficiencies such as the “3G tail,” a period in which the ad continues using the phone’s 3G connection when it no longer needs to. The team argues that reducing these inefficiencies can make apps that serve ads much less power-hungry.

The team plans on making their custom app, EProf, available as an open-source tool. According to the Verge, a version of the tool for Windows Phone is on its way as well.

Tested: Windows 7 Beats Windows 8 Preview in Battery Life, File Copy, More

Unfortunately, the Windows 8  file transfer speeds on our test systems weren’t as good as the boot times. When we performed the LAPTOP file transfer test, which involves copying 4.97GB of mixed media files, on the Dell Inspiron 15 M5030, the results were about on-par in both operating systems, with Windows 7 producing a rate of 24 MBps to Windows 8's slight-slower 23 MBps.

The difference between Windows 7 and Windows 8 transfer speeds was truly significant on the Samsung Series 7 and ASUS Zenbook UX31. Where, on Windows 7, the tablet and notebook copied the files at rates of 68 and 98 MBps respectively, on Windows 8, the transfer rates dropped to just 27 MBps on the Samsung Series 7 and 34 MBps on the Zenbook.

Synthetic test results were basically flat. On PCMark07, a benchmark that measures overall performance, the Dell Inspiron 15 M5030 and ASUS Zenbook UX31 saw very marginal increases in score, with the M5030 jumping from a low 1,278 to a slightly better 1,442 and the UX31 increasing its scored from 3,606 to 3,964. However, a difference of 100 points or 200 points on PCMark07 can occur between one run of the software and another so these increases were well within the margin of error. The Samsung Series 7 Slate could not run PCMark07.

When we ran the OpenOffice Spreadsheet Test — which matches 20,000 names to addresses — the Samsung Series 7 took 14 minutes and 8 seconds to complete the test in Windows 8, but  just 12 minutes and 45 seconds in Windows 7. On the same test, the ASUS Zenbook UX31 also saw a decrease in performance as it went from 5 minutes and 50 seconds in Windows 7 to 8 minutes and 55 seconds in Windows 8. Unfortunately, we could not perform the OpenOffice Spreadsheet test on the Dell Inspiron 15 M5030.

Running the same applications, graphics performance on our test systems was about the same on both OSes. On 3DMark06, the Inspiron 15 M5030 scored 1,689 in Windows 8, nearly the same as the  1,725 it achieved using Windows 7. The M5030 also achieved comparable frame rates when playing games in Windows 8. When we ran “World of Warcraft” on Good settings, the M5030 averaged 17 frames per second, on par with the game’s performance on Windows 7.

Graphics performance on the Samsung Series 7 was also fairly similar on both with OSes. On 3DMark06, the tablet notched a Windows 8 score of 1,650 nearly identical to the 1,642 scored on Windows 7. In “World of Warcraft,” the Samsung Series 7 achieved an unplayable 11 fps using Windows 8, compared to a slightly better (but also unplayable) 13 fps on Windows 7.

The ASUS Zenbook, by contrast, achieved slightly better graphics performance using Windows 8 than it had with Windows 7. Using Windows 8, the notebook notched a score of 4,360 on 3DMark06, up noticeably from 3,761 on Windows 7. Playing “World of Warcraft” with Good settings, the Zenbook UX31 turned in a frame rate of 28 fps that was imperceptibly better than the 26 fps it achieved with Windows 7. After turning the settings up to Ultra, “World of Warcraft” ran at just 13 fps, on par with its frame rate on Windows 7.

Though it’s supposed to be more power efficient, in our tests, Windows 8 provided noticeably less endurance  than its predecessor on the Dell Inspiron 15 M5030, Samsung Series 7 Slate PC and ASUS Zenbook UX31. On the LAPTOP Battery Test (continuous surfing on the Web using Wi-Fi and Firefox), the Inspiron 15 lasted 3 hours and 7 minutes on Windows 7, but only 2 hours and 45 minutes on Windows 8.

The Zenbook UX31 experienced an hour decrease in battery life, dropping from 5 hours and 58 minutes on Windows 7 to 4 hours and 55 minutes on Windows 8. The decrease in battery life was most dramatic on the Samsung Series 7, which lasted a reasonable 5 hours and 49 minutes while using Windows 7, but just 3 hours and 36 minutes on Windows 8.

It’s way too early to say that Windows 8 will offer lower battery life or slower file copies when it launches sometime later this year. It’s also too soon to say spreadsheet performance will suffer under Windows 8. Most likely the differences we saw were due to driver or hardware support issues that should improve over time.

Asus Transformer TF101 Mobile Docking Station: Great Battery Life, Tiny Keys

Asus Transformer TF101 Mobile Docking StationThe Asus Eee Pad Transformer TF101 tablet gets its name from the keyboard dock add-on that transforms the tablet into a laptop-like device. The Transformer TF101 Mobile Docking Station ($150 of March 7, 2012) is a must-have accessory for your Transformer, and not just because it gives you the ability to type on a physical keyboard.

The tablet slots into a rotating hinge at the back, and connects via a 40-pin dock connector. A release latch slides into place to secure it. Despite the large connecting port, the latch, and the wide hinge, however, the tablet still has a lot of room to wobble back and forth. I found this issue most noticeable when I folded the tablet down over the keyboard for transport: Whereas you would expect a laptop to fold solidly in half, with the screen edges sitting flush with the edges of the bottom portion, the Transformer didn't line up as nicely with its keyboard.

The keyboard also adds a lot of bulk to an already heavy tablet--a full 1.4 pounds and 1.1 inches, to be exact. That makes the whole kit similar in size, weight, and thickness to your average netbook. But this keyboard can do one neat thing a netbook keyboard can't: It comes off. So for those times you just want to put your feet up and swipe your way through the Internet, you can leave the keyboard behind. When you want to do some work on your novel, you just plug it back in. And having the whole thing fold together is a design advantage for when you’re pulling the keyboard/tablet combo out of your bag for going through airport security, for example.

Another major advantage of the laptop-like hinge that connects the Transformer to its dock is the fact that it holds the tablet up. You won't need any extra stands or folding cases. The hinge also rotates down as you raise the tablet into the "open" position, which lifts the keyboard to a nice angle for typing. It's surprisingly well balanced. Usually, a device combination like this--with all the "guts" in the screen--ends up being top-heavy and easy to tip backward, but in my tests the Transformer stayed firmly in place, even when I tilted the screen back a good ways.

I found typing on the Transformer dock to be mixed, unfortunately. The island-style keys are small and cramped, practically the same as what you’d find on an Asus netbook. They worked, but were not as comfortable to type on compared with the keys on the Lenovo ThinkPad Tablet Keyboard Folio Case; I had to adjust my hands a lot more to accommodate the spacing. It's the kind of spacing you could get used to over time, but it didn't feel natural from the get-go.

Luckily, the feedback was good--not too mushy, not too springy. Once you get accustomed to the spacing, typing on this keyboard could be described as workable. When you combine passable typing with all the other benefits of the keyboard dock, you get a valuable add-on for the Asus Eee Pad Transformer TF101 tablet.

Latest on the iPad 3: Dual-Core (Not Quad-Core) CPU, Bigger Battery, and March Unveil Date

iPad 3 leaked photos of casing

Apple’s iPad 3 announcement is imminent, so it’s no surprise that firmer details on that tablet are surfacing. At least according to sources who spoke to The Verge, hopes for a quad-core iPad may be a bit too lofty. Instead, the next tablet could run a dual-core processor like its predecessor.

More news comes from Cult of Mac, which posted leaked images of the tablet’s internal components. The photos, provided by UK iDevice repair specialist iPatch, indicate that the iPad 3's inside are quite different from what’s under the iPad 2's hood. The design of components such as the cable for the volume, wake/sleep, and mute buttons is significantly changed, though the photos don’t indicate that the iPad 3 will look dramatically different from the iPad 2 on the outside. Most interesting, though, is that it looks like the iPad 3 is designed to accommodate a larger battery.

One more update to your ever-changing iPad 3 forecast: Don’t count on that announcement happening in February. As we previously reported, it’s been widely expected that Apple will unveil the tablet early this month and release it in March, but All Things D reports that the iPad 3 will happen the first week of March.

41 Battery Tips for Android, iOS, Windows 7, and Mac OS X

You know that sinking feeling. That sense of desperation when your gadget’s battery meter says 10 percent .?.?. or less. Without your phone—or tablet or laptop—you’re lost, unable to work, unable to communicate with loved ones. And the really scary thing is that the lower the battery meter gets, the faster it seems to deplete.

Over the past few years we’ve seen some pretty amazing advancements in mobile technology. There’s now quad-core processors inside tablets, high-def displays for phones and don’t forget 4G. Meanwhile, laptops are now so thin you can practically floss with them, but there’s less and less room for beefy batteries.

So what are the juice-starved masses supposed to do, walk around with a power cord hanging out of their pocket? No, but there are plenty of small tweaks that can make a big difference. “When I pick up some of my friends’ phones, I look at all of the stuff that they’ve downloaded once and don’t realize that it runs a background service,” said Rob Chandhok, senior vice president of software strategy for Qualcomm. “You get to a point where you have to get some help in managing that.”

To help you squeeze more juice out of your gear, we’ve rounded up dozens of tips and broken them down by platform, including Android, iOS, Mac and Windows. The good news is that tech companies aren’t just leaving users to fend for themselves.

Ten Tips to Extend Your Mac’s Laptop Battery Life

Disabling your notebook’s wireless radios is one surefire way to eke out more juice. While turning off Wi-Fi may not be practical in every situation—especially if you need to access the Internet often—it will give you more endurance if you’re using your laptop to watch a movie on an airplane.

To turn Bluetooth off:

Click the Bluetooth icon in the upper right-hand corner of the desktop.Select Turn Bluetooth Off. The icon should now be grayed out.

Alternatively:

Select System Preferences > Bluetooth.Uncheck the box marked On.

To turn Wi-Fi off:

Click on the Wi-Fi icon in the upper right-hand corner of the desktop.Select Turn Wi-Fi Off. The icon should change from a number of concentric arcs to an outline that looks like a baseball diamond.

Alternatively:

Open System Preferences > Network.Uncheck the box marked Turn Wi-Fi Off.

At full brightness, the 13-inch MacBook Air’s screen measures an average of 285 lux. At 40-percent brightness (6 bars), it’s just 29 lux, but still very viewable. And brightness eats power.

To lower screen brightness:

Tap F1 repeatedly until the brightness is at a level just tolerable enough to view comfortably.

Alternatively:

Open System Preferences > Displays.Adjust the Brightness slider to the level you’re most comfortable with.

Changing these settings will cause your Mac to power down energy-consuming components—such as the screen and the hard drive—sooner during periods of inactivity.

Click System Preferences.Open Energy Saver.Select the Battery tab.Move the slider bars for Computer Sleep and Display Sleep as far left as you believe is comfortable. You probably don’t want your computer going to sleep after just one minute but don’t want to leave it on indefinitely either.Below, select the following checkboxes:Put the hard disk(s) to sleep when possible.Slightly dim the display when using this power source.Automatically reduce brightness before display goes to sleep.

Occasionally, an app will consume an inordinate amount of system resources even when not in use. Not only does this impact your notebook’s performance, but it also seriously degrades battery life.

Open the Applications folder > Utilities folder.Click Activity Monitor.Select the CPU tab.Select All Processes in the drop-down menu.Sort the apps by CPU percentage.Look for any app that is consuming a large percentage, such as more than 70 percent.Select that app and press the Quit Process icon.

Alternatively, if you know an app is hanging, you can force-quit the app.

Press Command + Option + Esc.In the window that appears, select the app that’s not responding and force-quit.

While it’s a great feature, the backlit keyboard on Macs can shave precious minutes off your runtime.

To turn off the backlit keyboard:

Hit the F5 key repeatedly until the on-screen icon shows no bars lit.

Alternatively:

Open System Preferences.Select Keyboard.Uncheck the box marked “Automatically illuminate keyboard in low light.”Underneath where it says “Turn off when computer is not used for,” move the slider to 5 secs.

11 Ways to Increase Your Windows 7 Laptop’s Battery Life

Your screen backlight uses the most power of any component in your notebook, so you can save a lot of juice by turning it down to the lowest acceptable level. You can manually raise and lower the brightness in increments of 10 percent by hitting the appropriate key combination for your laptop (example: Fn + left/right arrows on the Acer Aspire TimelineX series), but we recommend changing the brightness in your power profile so it lowers automatically every time you unplug.

To lower the brightness level in your power profile:

Select Power Options from the control panel.Click Change Plan Settings next to your current power plan.Select “Change advanced power settings.”Expand Display, then Display brightness.Enter a brightness percentage for On Battery, then Click OK.Experiment with different brightness levels to determine which is the lowest you can tolerate.

Your virus scanner and disk defragmenter, along with auto updates from the likes of Apple and Google, are scheduled to run themselves on a regular basis—often without your knowledge or consent. Set these tasks to run only on AC power so they don’t eat up precious juice running your hard drive, CPU and wireless while you’re unplugged.

Select Administrative Tools > Task Scheduler in the Control Panel.Select Task Scheduler (Local) in the left window pane.Go through each active task that has a future date in the Next Run Time column and do the following:Double-click the task.Select the Conditions tab.Toggle on the first two power options: “Start the task only if the computer is on AC power” and “Stop if the computer switches to battery power” if they are not already checked.Click the back button to return to the list of active tasks.

If your notebook has a backlit keyboard, it will certainly help you see keys in a dark room, but it’s also sucking juice out of your battery. You’ll save some power by turning off that light. Every notebook has its own way of enabling or disabling its keyboard backlight, but the method usually involves hitting a Function key on the top row of the keyboard.

Every USB peripheral attached to your notebook is eating up power just by registering itself with the operating system. By the same token, CDs, DVDs and Blu-rays can drain battery life, even when they’re just sitting idle in your optical drive. Remove any discs along with USB keys, card readers, modems or other peripherals you don’t need while on battery power.

The LED-backlit screens used on most modern notebooks expend less energy displaying black pixels than those showing colors. Setting your computer to show white and yellow text on a black background can improve battery life and even make text more readable when sunlight is hitting your screen.

To enable High-Contrast mode in Windows 7, simply hit the key combination Left Shift + Left Alt + Print Screen and click Yes when asked to confirm. You can turn off High-Contrast mode by hitting the same combo.

High-Contrast mode will affect your desktop and most Windows programs, including the latest versions of Internet Explorer and Firefox. However, if you use the Chrome browser, you will need to install the Change Colors extension, which is available for free from the Chrome Web Store. Once the extension is installed, it will show an icon in the right side of your address bar. Click that icon and select “Apply override on all pages” to enable high-contrast mode.

While you’re surfing the Web, checking email or watching a movie, messaging apps such as Google Talk and Skype are hitting the Internet constantly, just to see which of your contacts are online and whether you’ve received any messages. Automatic updating apps from the likes of Adobe, Apple and Google may also be pinging the Internet to see if there are updates to your copies of Adobe Reader, Chrome browser or iTunes. To stop these silent power vampires before they start, prevent them from loading at boot time.

To see and disable programs from starting when your computer starts:

Type msconfig into the Start Menu text field, and click msconfig.Select the Startup tab.Uncheck messaging programs such as AOL Instant Messenger, Gtalk and Skype. You can always launch them manually if you want to use them.Uncheck autoupdaters such as Adobe Update, Apple Update, Google Update and Java Autoupdater.Click OK.
