How to increase your tablet's battery life

Tablets such as the iPad and the Motorola Xoom may be on their way to replacing conventional computers. A 2011 Nielsen survey found that 35 percent of desktop computer owners and 33 percent of laptop owners reduced their PC use or stopped using them altogether after they purchased a tablet. Unfortunately, as your tablet becomes your go-to device, you must wrestle with the same problem laptop and mobile-phone owners have faced for years: extending battery life while getting the most out of the device. While tablets are relatively new, the batteries inside haven’t changed a whole lot since the mid-1990s.

Improving the power consumption of a tablet is much like improving that of a mobile phone or laptop or even conserving energy at home: turn off what you don’t use, minimize the usage of features you do need and look for hidden features draining your battery. Here some step you can do it.

Instruction.
1. Reduce your screen’s brightness. This single step greatly improves your battery life. The screen is the largest power draw on a tablet. Dim your screen as much as you can handle without causing eyestrain. Some tasks, such as photo editing, may require full brightness, but reducing it for ordinary reading will pay off in extra uptime.

 2. Shorten the screen timeout interval. This feature called the Auto-Lock Interval on an iPad blacks out the screen when the tablet’s not in use. While you may have to touch the screen at regular intervals to keep the tablet awake while you read, you’ll extend your battery life significantly if you use the tablet frequently for short tasks like checking email or sending SMS messages. If you don't mind fiddling with settings, you can turn off the timeout when you're settling in for some reading, and then change it back afterwards.

3. Reduce or eliminate application updates, pings and syncs. For example, social media applications such as TweetDeck and Apple’s Ping update constantly by default, even when you’re not using them. Set applications to update manually whenever possible and you’ll conserve power even when your tablet is “asleep.” Likewise, Apple recommends turning off “push notifications” and email “push” settings on your iPad to conserve power.

4. Disable Bluetooth, Wi-Fi and GPS when they aren’t needed. Even when these services aren’t in use, they continue to search for connections and remain “powered up.” Some tablets offer a widget to quickly enable or disable these antennas when you’re not using them. If your tablet also uses 3G or 4G wireless service, disable it when you’re using Wi-Fi, or use "airplane mode" if you're photo editing or watching a downloaded movie.

 5. Keep an eye on the applications that run in the background. Some, such as games, should be shut down when you’re done with them. Others, such as GPS-enabled apps, might use more power than you expect while they’re in the background, because they’re also accessing your GPS antenna. Kill or quit any apps you don’t need.

6. If your tablet has an Organic Light Emitting Diode screen, a dark-colored wallpaper will reduce the screen’s power draw. Unfortunately, this method won't work with LCD screens, which are illuminated by a static backlight.

Tablets vs. Laptops on Campus

If you're looking for something to take with you from class to class on campus, the choice between a laptop or a tablet is hardly a simple one. Laptops have the advantage in terms of functionality, but tablets are lighter, cheaper and let's be honest a lot sexier. If you already have a computer to serve as your educational base station at home or in your dorm, your options are more open. But if you don't, you should probably choose a laptop. Laptops are better for multitasking, writing papers and using spreadsheets, and they have more options for the different ways you can get your work done.

1.Prices and Quality

If your budget is limited and you already have a desktop PC, a tablet may be the better way to go. Even a higher-priced tablet like the Apple iPad is going to give you better value than a laptop in the same price range. If you do decide to buy an inexpensive laptop, it's vital that you understand it's limitations. Reviews for different models vary, regardless of the manufacturer. Generally, you'll find most complaints about inexpensive netbooks revolve around freezing, slow multitasking and crashing.

2. Typing

If you're a touch-typist, nothing will beat a full-sized keyboard. If you have to look at the keys to type, the difference between a regular keyboard and that on a tablet may not be very noticeable. Keep in mind as well that you can get wireless keyboards for a tablet, most of which are about the same size as that on a netbook.

3.Taking Notes

If you're deciding whether to use a laptop or a notebook for taking notes in class, two deciding factors are portability and functionality. A laptop with a full-sized keyboard is not as compact as a tablet. A netbook is roughly the same size as a large tablet, but doesn't give you the full-sized keyboard. Two points in favor of tablets in this regard are keyboard cases and note-taking apps. Peripheral manufacturers Belkin and Kensington both offer tablet cases that come with a Bluetooth keyboard, essentially turning a tablet into a laptop for about $100. You can set it on a table or adjust the angle to perch it on your lap. With a stylus and a note-taking app, you can write your notes on the tablet and store them for future reference. It may take a bit of practice to get used to the feel of a stylus on a touchscreen, but it shouldn't take too long.

4. E-Books

Colleges and universities across the country have started embracing e-books. This is great news if you have a tablet, but not quite as good if you rely on a laptop. With a tablet or e-book reader you can curl up in a chair, read in bed, or even on the bus rather comfortably. Reading on a laptop is not quite as comfortable in these situations. Laptops can overheat when you nestle them against pillows. Balancing an open laptop on a crowded, moving bus may be good fodder for a sitcom premise, but not so good for your laptop. However, when it comes to copying a quoted passage from an e-book into a paper you're writing, while also researching biographical information about the author and viewing his birth city on a map, laptops do have an advantage bringing the topic to multitasking.

5. Multitasking

Not a lot of tablets that are capable of true multitasking at the moment, but that's changing fast. The Samsung Galaxy 10.1, released in 2012, can display two windows simultaneously. Other tablets, like the third-generation iPad, for example, can keep one app active while you switch to another. You can copy and paste from one app to another, but you can't see more than one app at a time. If your tablet doesn't let you multitask, using it for writing papers using online sources or e-books will quickly become frustrating.
