Guide to Laptop Storage Drives

How to Choose a Laptop Based on HDD, SSD, CD, DVD and Blu-ray Options
Most modern laptops are moving away from the traditional mechanical drives in favor of more durable and smaller solid state options.
This change is being fueled by the fact that laptops keep getting smaller, and so their internal space is restricted and no longer accommodating for larger storage devices.
To help clear up confusion for buyers, this guide looks at all the various types of drives that may be in a laptop, and what they can offer.
Hard Drives
Hard drives (HDDs) are still the most common form of storage in a laptop and are pretty straight forward.
Generally, the drive will be referred to by its capacity and rotational speed. Larger capacity drives tend to perform better than smaller ones and faster spinning drives, when compared with ones of similar capacity, are usually more responsive than slower ones.
However, slower spinning HDDs do have a slight advantage when it comes to laptop running times because they draw less power.
Laptop drives are typically 2.5 inches in size and can range from 160 GB up to over 2 TB in capacity. Most systems will have between 500 GB and 1 TB of storage, which is more than enough for the standard laptop system.
If you're looking at a laptop to replace your desktop as your primary system that will hold all your documents, videos, programs, etc., consider getting one with a hard drive that's 750 GB or larger.
Solid State Drives
Solid state drives (SSDs) are starting to replace hard drives in more laptops, especially the new ultrathin laptops.
These types of hard drives use a set of flash memory chips rather than a magnetic platter to store the data. They provide faster data access, lower power consumption, and higher reliability.
The downside is that SSDs don't come in such large capacities as traditional hard drives. Plus, they usually cost a lot more.
A typical laptop equipped with a solid state drive will have anywhere from 16 GB to 512 GB of storage space, although there are some available with more than 500 GB but they are prohibitively expensive. If this is the only storage in the laptop, it should have at least 120 GB of space but ideally around 240 GB or more.
The type of interface that the solid state drive uses can also have a significant impact on the performance but many companies do not overtly advertise it. Most inexpensive systems like Chromebooks tend to use eMMC which isn't much more than a flash memory card, while high performance laptops use the new M.2 cards with PCI Express (PCIe).
Solid State Hybrid Drives
If you want higher performance than a traditional hard drive but don't want to sacrifice storage capacity, a solid state hybrid drive (SSHD) is another option. Some companies are referring to these as just hybrid hard drives.
Solid state hybrid drives include a small amount of solid state memory on a traditional hard drive that is used to cache frequently used files.
They do help speed up tasks such as booting up a laptop but they aren't always faster. In fact, this form of drive is best used when a limited number of applications are used on a frequent basis.
Smart Response Technology and SSD Cache
Similar to hybrid hard drives, some laptops are using both traditional hard drives with a small solid state drive. The most common form of this uses the Intel Smart Response Technology. This provides the benefits of the storage capacities of the hard drive while gaining the speed benefits of a solid state drive.
Unlike SSHDs, these caching mechanisms usually use larger drives between 16 and 64 GB that provide a boost to a larger range of frequently used applications, thanks to the extra space.
Some older ultrabooks use a form of SSD caching that offers higher storage capacities or lower costs, but Intel has changed this so that a dedicated solid state drive is required in order for new machines to meet the ultrabook branding requirements.
This is becoming much less common now that prices for SSD's continue to drop.
CD, DVD and Blu-ray Drives
It used to be that you were required to have an optical drive on a laptop since most software was distributed on discs, so it was required in order to load the program to your computer. However, with the rise of digital distribution and alternate methods of booting, optical drives are not a requirement like they once were.
These days, they're used more for watching movies or playing games, as well as burning programs to a disc, creating DVDs, or building audio CDs.
If you do need an optical drive, what type of drive should you get on a laptop? Well, whatever you end up getting, it should definitely be compatible with DVDs. One of the great advantages to laptops is their ability to be used as portable DVD players. Anyone who travels regularly has seen at least one person pull out a laptop and start watching a movie during the flight.
DVD writers are pretty much standard for laptops that have an optical drive. They can fully read and write both CD and DVD formats. This makes them extremely useful for those looking to watch DVD movies on the go or for editing their own DVD movies.
Now that Blu-ray has become the defacto high definition standard, more laptops are beginning to ship with these drives.
Blu-ray combo drives have all the features of a traditional DVD burner with the ability to play Blu-ray movies. Blu-ray writers add the ability to burn lots of data or video to the BD-R and BD-RE media.
Here are some optical drive options and the tasks they are best suited for:
Ÿ   Basic computing w/DVD Playback: DVD-ROM
Ÿ   DVD/CD Recording: DVD Writer
Ÿ   HD Video Playback: Blu-ray Combo
Ÿ   HD Video Recording: Blu-ray Writer
With current component costs, there is almost no reason that a laptop would not have a DVD burner if it is going to have an optical drive. What is surprising is that Blu-ray drives have not become more standard as their prices are also quite low now for the combo drives. It should also be noted that laptop drives are generally much slower than similar drives found in desktop systems.
Even if a laptop does not have an internal optical drive, it's still possible to use one so long as you have an open USB port for room to attach a USB optical drive.
Note: When you purchase a laptop with an optical drive, it may require additional software beyond the operating system to properly view DVD or Blu-ray movies.
Drive Accessibility
Drive accessibility is important when considering whether to upgrade or replace a damaged drive. It's important to know what you're doing, so you might consider having an authorized technician open the computer.
This generally isn't a problem for many people, but in a corporate environment it can cause increased down time for a worker. Laptops that have drive bays that are accessible or swappable have the advantage of easy and quick access for upgrades or replacements.
In addition to being accessible, it's also important to get an idea of what kind of drive bays there are and what the size requirements may be. For instance, the 2.5-inch drive bays used for hard drives and solid state drives can come in several sizes. The larger 9.5 mm drives often have better performance and capacities but if the drive bay only fits 7.0 mm drives due to a thin profile, you need to know that.

Similarly, some systems use the mSATA or M.2 cards rather than a traditional 2.5-inch hard drive for their solid state drive. So, if the drives can be accessed and replaced, be sure to know what type of interfaces and physical size limits there are.

Clean A Mousepad

Mousepads are a great way to help your mouse move more smoothly. Some of them even come with extra cushioning for support. Sometimes, they get dirty and need to be cleaned. To quickly clean a fabric or plastic-covered mousepad, rub it with a moist rag and some shampoo. Use a clean rag and water to rinse off the shampoo, then let your mousepad dry completely.
How to clean a mousepad?
Check out what your mousepad is made of. Usually it will be a spongy foam, covered with either a finely knit fabric or a plastic top. Clean it according to the type of surface. If the surface is fabric, try rubbing gently with a moist washcloth or rag and a bit of shampoo. Shampoo is a mild cleaner that's gentle on most fabrics and on skin, plus you already have it. If your mousepad is plastic-covered, use any mild spray household cleaner and a cloth or sponge. Dish soap or shampoo will work just as well.
Rinse all the cleaner off the mousepad. Pat the outside of the mousepad dry. Allow the mousepad to dry thoroughly. Let it dry all the way through the foam before returning it to your desk.
Community Q&A
1.What should I do if the fabric mouse pad I cleaned now has a bump?
Try cleaning it again with hot water and soap, and then hang it to dry. That should stop bumps from forming as well as get rid of any existing bumps.
2.What if the mouse pad has a drawing on it? Should I worry about it at all?

It shouldn't be a problem on plastic mousepads, because the plastic is covering the drawing. However, if it is a spongy foam fabric, you may want to be gentler when cleaning.

How Do You Know When It’s Time to Replace Your Battery?

Batteries don’t last forever. As you charge and discharge your battery, it degrades and over time, you get less battery life from a full charge. Eventually, the battery—or the device—needs to be replaced.
Battery Capacity Decreases Over Time
A battery doesn’t just go from good one day to bad the next. Instead, batteries slowly degrade over time. This capacity decrease is a gradual process—happening over many charge cycles—and you won’t necessarily notice until you realize you used to get a few more hours of battery power from a charge.
You can help prolong your battery’s life and keep its capacity up by properly caring for your battery. But you can’t avoid battery degradation forever. If you replace devices often—say a new phone every couple of years—you may never notice. Or, you may notice but the problem won’t get bad enough to do anything about before it’s time to replace your device again. But for devices like laptops, which you’re likely to keep for longer, you may have to replace your battery at some point.
Some devices will even warn you when it’s getting time to replace your battery. For other devices, you can often find third-party apps that let you check up on your battery’s health.
How to View a Device’s Battery Health
Unfortunately, many devices don’t display battery health warnings ahead of time. You’ll either notice a problem yourself or the battery will simply fail. Even devices that do include some kind of warning often don’t give you much advance notice. It pays to check up on battery health yourself once in a while.
Here’s how to find battery health information on some common operating systems and devices:
Ÿ   Windows Laptops: We recommend NirSoft’s BatteryInfoView to find a Windows laptop’s battery health, but there are other utilities you can use instead.
Ÿ   MacBooks: Hold down the Option key and click the battery icon on the menu bar. You’ll see a “Condition:” line displayed here.
Ÿ   iPhones and iPads: You can actually ask Apple support to tell you your iPhone or iPad’s battery health
Ÿ   Android Phones: Unfortunately, most Android users are out of luck. Some older phones would show battery health information if you opened the dialer and typed *#*#4636#*#*, but this doesn’t seem to work on modern phones.
For other devices, search for the type of device and “battery health” to get instructions.
When It’s Time to Replace a Battery
Whatever your device says about the health of its battery, the rest is up to you. If your battery reports it’s at 40 percent of its original capacity, but you’re still happy with how much battery life you get, there’s not much need to pay for a replacement until it declines to a point where it becomes bothersome.
How to Replace a Battery
If you have a smartphone, tablet, laptop, or another device with a removable battery, replacement is easy. You just need to purchase a replacement battery designed specifically for your device, power down your device, and then replace the current battery with the new one. This gives your device a fresh battery with maximum capacity.
However, devices these days are often made so that you can’t access the battery yourself—at least not easily or without voiding your warranty. Instead, you’ll need to have the manufacturer replace the battery for you. For example, you can take an old iPhone, iPad, or MacBook to an Apple Store and pay a fee to have Apple employees open your device and replace the battery for you. Check if your manufacturer offers this service.
Of course, even on devices without an easily accessible battery, if you’re so inclined and don’t mind the associated risks, you always have the option of doing it yourself. You could  open up your device, get a replacement battery, and try to seal it back up again. We don’t necessarily recommend this, though. Too many modern devices have batteries and other components that are glued together and not designed to be opened.
The battery health status your device reports can help you decide whether it’s time to replace your battery, but the decision is ultimately up to you. If your battery feels okay to you, then you don’t need to do a thing right now. Better to put that money toward a future device replacement. If the battery is no longer performing adequately and you’re not interested in replacing your device, then it’s time for a replacement.

Type Fast On A Keyboard

Do you want to learn how to type fast in the most efficient way? Follow these instructions, and you will be on your way to type fast on a keyboard.
1.Changing your keyboard
If you are going for speed, choosing the standard keyboard layout is out of the question. You must remember where are the buttons on keyboard. If you are a beginner at typing try to write your name or something you are familiar with your school name or your address etc. To learn more about the layouts. Notice that you don't have to buy a new keyboard, just change a setting on your computer.
2.Improving your speed
Before you type, warm up your fingers by making fists with both your hands. Open them slowly, and bend your fingers back until they can't physically go further without external help. Repeat this five times and you'll be typing faster than you did before. Try not to look at the keyboard when typing. Challenge yourself at all times until you can type without looking at all, and get the typing accurate.
3.Use websites that allow you to practice touch typing
Practice at the various levels until you are using the fastest typing levels. Use timed typing tests that require you to beat the clock to finish a paragraph.
4.Find a touch typing tutor and learn to type
There are tons of free alternatives that should fit most people fine. Don't move the keys around. This will only slow down your learning. To speed up your learning, try to practice with text that makes sense, and not the usual repetitive sequences of characters - these do not really work.
5.When you are ready to take a shot at beating the world record, and choose a test, preferably with a three minute duration to get a more accurate result.
To motivate yourself, make notes of your results before, during and after your training to see the increase in speed. Choose different tests, so that you don't end up memorizing a text.

How to Increase Your Windows Laptop’s Battery Life

We often fixate on smartphone battery life, but most laptops still don’t have all-day battery life. Rather than tethering your laptop to an outlet, here are some ways to squeeze more life from your laptop’s battery.
None of these tricks will turn a laptop without much stamina into an all-day workhorse, but they’ll help you go without an outlet for a while longer. Pay particular attention to your laptop’s display—that’s a big battery sucker.
Use Windows 10’s Battery Saver Mode
If you want to extend your battery life without thinking too much about it, enable Windows 10’s Battery Saver mode. Windows automatically enables this feature when you’re down to 20% battery by default, but you can manually enable it whenever you like. So, if you know you’ll be away from an outlet for a while, you might enable it at the start of a long day.
Battery saver performs a few tweaks automatically, like limiting background activity and lowering screen brightness to achieve longer battery life.
To enable Battery Saver mode, click the battery icon in your notification area and drag the Power mode slider to the “Best battery life” point on the left.
Reduce Your Display’s Brightness
The biggest battery drain on any modern portable electronic device—whether it’s a laptop, smartphone, or tablet—is the display. Reducing your screen’s brightness is a simple way to squeeze significantly more time from your laptop’s battery.
On a typical laptop, you’ll just need to press the brightness buttons on your laptop keyboard (on some laptops, you may need to hold the Function (Fn) key while pressing the brightness buttons). The lower the brightness level, the longer you can use your laptop on battery power.
On Windows 10, you can also open the Action Center by clicking the notification icon on your taskbar and click the brightness icon to adjust brightness (click “Expand” if you can’t see it). You can also head to Settings > System > Display and adjust the slider here
Check Which Applications Are Using the Most Battery on Windows 10
Windows 10 allows you to see which applications are draining your battery the most. It does this by tracking CPU usage over time, then listing which programs are using the most power. This feature isn’t available in Windows 7.
To access this list, head to Settings > System > Battery > Battery Usage By App. This screen will show you which applications are using the most battery. This doesn’t necessarily mean the application is bad—the applications you use the most will probably have used the most battery power, of course. But you may want to consider switching to more power-friendly applications if something is unusually heavy, or close background applications that seem to use a lot of power even when you’re not actively using them.
Turn Off Your Screen and Go to Sleep Sooner
Since the display uses so much power, it’s important not to have it on longer than necessary. You can configure your laptop to automatically go to sleep sooner when you’re not actively using it—or at least turn off its display to save power.
This won’t help your battery life if you’re actively using the laptop the whole time, or always put it to sleep immediately when you’re done, but it can ensure your laptop doesn’t waste power by running for too long when you step away.
Disable Bluetooth and Other Hardware Devices
Hardware devices you don’t use can also waste battery power for no good reason. For example, if you never use any Bluetooth accessories with your laptop, you can turn off the Bluetooth hardware radio to eke out some more battery life. (f you do use Bluetooth accessories regularly, toggling Bluetooth on and off may not be worth the trouble, as the Bluetooth hardware in modern laptops is more power efficient than it once was.)
Tweak Your Power Plan
On Windows 7, you can save energy by selecting the “Power saver” Power Plan from Control Panel > Hardware and Sound > Power Options. This isn’t necessary on Windows 10, as you can just use Battery saver mode instead.
You can change a variety of settings from the Power Options window that appears, including configuring your laptop to power off its hard drive more quickly and telling your computer to slow down the processor rather than turning on the fan if it becomes hot. Both of these behaviors will save power. The default settings should be fairly optimal if you select Power saver mode, but you can make the settings even more aggressive in some areas, if you like.
Run the Windows Power Troubleshooter
Windows 7, 8, and 10 include a power troubleshooting tool that will scan your system for common battery drains and automatically fix them. For example, this tool will automatically decrease the time before the display dims if it’s too long, or disable the unnecessary screensaver feature if it’s enabled.
Lighten Your Software Load
To save power, make your computer do less in general. For example:
Ÿ   Don’t use a screensaver. They’re unnecessary on modern displays and will drain your battery to do nothing useful when your display could be off and saving power.
Ÿ   Run fewer programs in the background. Examine your system tray for programs you don’t need and uninstall them or disable them and prevent them from automatically starting with your computer.
Ÿ   Reduce CPU usage. If you use heavy programs that have your CPU doing a lot of work all of the time, your CPU will use more power and your battery will drain faster. Running fewer programs in the background can help with this, as can selecting lightweight programs that are easy on system resources.
Ÿ   Avoid maxing out your RAM. If your computer fills its RAM and needs more memory, it will move data to the page file on its hard drive or SSD, and this can drain battery power. This shouldn’t be as much of a problem on modern computers with a decent amount of RAM. If your laptop’s RAM is full, try to make more RAM available—close programs running in the background or even upgrade your laptop’s RAM.
The less your computer has to do, the more power it can save. You can find more information about CPU and RAM usage in your Task Manager.
Take Care of Your Laptop Battery
All batteries lose capacity over time, so your laptop’s battery life will decline no matter what you do. But there are ways to keep your battery as healthy as possible.
For example, don’t always run your laptop down to 0% battery—try to charge it before that. Over the long run, keeping your laptop battery cool will also prevent unnecessary wear and tear caused by heat. Heat is a battery’s biggest enemy.

Tips and Q&A to Clean A Laptop Screen

Laptop screens tend to collect dust, food particles and other debris that starts to look unattractive after a while. It's important to use very gentle supplies to clean your laptop screen, since the LCD surface is easily damaged. Here are attached tips and Q&A for your reference.
Tips
Tissues, napkins, and other paper products will leave flakes of paper on your monitor. It's better to not even try using them. They can contain wood fibers and may even scratch polished surfaces. You don't want mineral spots on your screen, so don't use tap water. If you're a photographer, you can use your lint-free lens wipes instead of a soft cotton cloth. If you have lens cleaner for eyeglasses, check the back to see if it contains "Isopropanol", if it does don't use it on your LCD monitor. Use a cotton swab for the harder to reach places with the cleaning solution on it. If you apply too much of the solution and it is drippy or too damp, wipe it off with a soft cloth and apply less. Clean and then let it soak for a little and then repeat. Be patient with hard to clean spots. If in doubt, test a small area of screen first.
Community Q&A
1.How can I clean a laptop keyboard?
Try using the sticky side of a sticky note in between the keys to pick up dirt and dust.
2.Are there similar types of cloth I can use instead of microfiber?
Anything made of cotton is gentle enough to use on a laptop screen, but you should avoid using paper towels or facial tissue, which are too abrasive for this type of cleaning.
3.Where can I buy a microfiber cloth?
Most supermarkets have them, as well as office supply stores.
4.Can I use cotton for cleaning a laptop screen rather than microfiber?
Yes, as long as it is a gentle, soft kind, like t-shirt material.
5.Can Lysol wipes be used to clean a laptop screen?
No, it is too harsh. Use only water and white vinegar solution with a microfiber or soft cotton cloth, like an old t-shirt.
6.Can you use Clorox wipes or baby wipes to clean your laptop screen?
No. If you have eyeglasses cleaner, I suggest using some of that. Don't spray it directly on the screen or it could get into your laptop.
7.How can I get better at not being distracted when I work on my homework?
Get all the distractions out of the room and take breaks every once in a while.
8.What is the best way to clean a flat screen TV with fingerprints on it?
Take some dryer sheets and wipe across the TV lightly, if there's dust. Then take a microfiber cloth and clean it like you would a computer screen.
9.What should I do if my screen is foggy due to cleaning solution?
I used distilled vinegar and water with a microfiber cloth for mine. It worked well for me.

How to get more storage space for your tablet

Always running out of space on your tablet? Whatever tablet you use, here are some easy ways to get more storage space.
People use tablets for different things. Some browse the web, others read their email and some use it as an entertainment device.
If you listen to music, watch moves, take photographs and download apps on your tablet, there’s a high chance your tablets drive will quickly become full and you won’t be able to download anything else.
Here are some ways to get more storage space for your tablet.
Free up storage
Start by spring cleaning your tablet and removing the apps and files you don’t use. You’ll be surprised how much storage space is taken up with things you don’t even use.
Hardware
Memory card
If you own an Android tablet such as the Google Nexus 9 or the Tesco Hudl 2 then it may have a slot for a memory card. The advantage of using a card is that you can keep it in your tablet and use to store content and apps.
Invest in a card reader
A wireless portable card reader is a good solution if you don’t have a card slot on your device, but want to access extra content such as movies, photos and videos.
Storage drive
A storage drive is a good way of backing up things that you don’t use every day. Photographs, for example, take up quite a lot of storage space, but it’s likely you won’t want to look at them all that often.
Plugging in a portable drive enables you to quickly transfer photographs and free up storage space. A portable hard drive is a good place to store music and movies you don’t want to keep on your tablet.
Wireless storage
If you don’t want to mess around with cables or formatting, or if you’re an Apple iPad owner, a wireless storage drive will be more convenient.
Apple doesn’t make it easy for iPad users to add extra storage to their tablets. The device doesn’t include a USB port and uses a proprietary charging port, either 30-pin in the iPad 2 or the new Lightning connector.
Cloud storage
The advantage of using the cloud to store things is that you aren’t using storage space on your tablet. Instead your files are stored on remote servers, commonly known as the cloud.
Cloud storage has other advantages. Many devices enable you to set up an automatic backup so you don’t have to worry about remembering to copy your files manually. Additionally, in the event you lose your device, you’ll be able to restore your files from backup.
A number of cloud storage providers that offer space without charge.
BT Cloud
With BT Cloud, BT customers get 50GB or 500GB storage free depending on the broadband package.
BT Cloud can be used to store photos, music and documents.
You can access BT Cloud from any device with a browser, or via the BT Cloud app which is available for Android, Apple and Windows Phone phones and tablets, using your BT ID. From there you can share your content with family and friends.
Apple iCloud
Apple Pad and iPhone users get 5GB of iCloud storage free with their devices.
Google Android
Google offers users 15GB storage across Google Drive.
Users of Android tablets, such as the Tesco Hudl, can turn on automatic backups to back up app information, settings and wi-fi passwords by heading to Settings – Backup & reset – Back up my data.

How to fix your Android phone’s terrible battery life

It’s the early afternoon, and your Android phone is already running on “E.” What’s the deal? A smartphone is supposed to be the hub of your digital life, but it can’t do that very well when the battery has run dry, can it?
You probably shouldn’t wait until your phone has failed you at a critical moment before you figure out what’s destroying your battery life—there’s no better time than now to track down the culprit. If you're lucky, you might even be able to fix the issue without sacrificing functionality.
Wakelocks and misery
Android has gotten much better at managing background processes in the last few years. Anyone who has used Google's platform since the early days can tell you how bad things used to be when “task killers” were a necessity. Even though Android as a whole isn't subject to the same horrible battery life issues, the wrong combination of apps can still break Android’s elegant process management scheme.
Conventional wisdom used to be that you should open the multitasking interface and kill any application you’re not using to save battery life, and unfortunately this superstition still persists. But Android knows how to manage background tasks, and swiping apps out of the multitasking interface only closes the foreground process. If an app is indeed causing issues, it's usually the background process that's doing it. This sort of micromanagement will only waste time.
Solving the case
It might not be immediately obvious that a phone is in wakelock for long periods. By all appearances, the screen is off and it seems to be asleep like it should be. One clue that something is going wrong is excess heat generation. When the CPU is cranked up instead of in deep sleep, the device might be noticeably warmer than usual when you pick it up. You'll need to do a little detective work, though, and that's where the apps come in handy.
One quick and easy way to watch for a phone that won't sleep is to use an app like System Monitor to track CPU clock speed. This app breaks down CPU activity as a percentage. Unless you've been using the device almost constantly, ”Deep Sleep” should be the largest part of the chart. If not, you've probably got a misbehaving app or system process.
You'll have to dig a little deeper in order to sort out the exact cause of your shortened battery life. The best app for this is BetterBatteryStats. The developer posts free beta builds on the XDA forums, but it's also for sale in Google Play. Rooted users see more information in the app, but you can still get some data on wakelocks with almost all devices.
Just give the app a few hours to calibrate, and then filter for Kernel Wakelocks and Since unplugged. If you see a process up near the top of that list with a lot of wakelock time, that's the guilty party. Kernel wakelocks are system processes like suspend_backoff or wlan. BBS BetterBatteryStats sometimes includes links to more information about wakelocks with some ideas for fixing them. Otherwise, you can search for information on the exact system process and find a likely solution. Often, a reboot will knock some sense into your phone and clear this up.
More often than not, the root of your problem will be some app you installed. The easiest way to deal with the issue is to leave the offending app or game uninstalled, but maybe you actually want to use the app despite its battery sucking behavior. In that case, you need a way to end the process safely. Android has a built-in way of hibernating processes, and you can easily trigger it with an app called Greenify.
Simply use Greenify to identify the problematic apps, and hit the hibernate button after you're done using them. Greenify works best with root access—it can handle all this in the background. For non-rooted devices, you can use the in-app button or a widget to manually trigger the hibernation routine.
Going through this process might seem like a hassle, but it's preferable to having a phone that can't hold a charge. It can also save you from disabling useful features like GPS or background sync in the name of eking a bit more life out of your device.

7 tips to extend your tablet’s battery life

Whether you’ve got a Tesco Hudl or a Nexus 7, a few simple tweaks can help you eke more life out of your Android tablet's battery.
Step 1: Check what's sapping your tablet's power
Android provides a quick and easy way to see what's draining most of your tablet's power. Go to Settings > Battery. This will show you a bar graph of the different hardware, apps and processes that are putting the most drain on your battery.
The greatest drain is almost always the screen, as powering the backlight for your tablet's large display uses a lot of energy.
Step 2: Turn the screen brightness level down
Adjusting the brightness level of your tablet’s screen can save a lot of battery power. To do this, open Settings > Display > Brightness. A pop-up window will display a slider which you can use to change the brightness level. If the slider isn’t visible untick the box marked Automatic Brightness. Reduce the brightness to a level that's less intense but still comfortable for you to read text on your screen without straining your eyes.
Step 3: Reduce the screen time out
Reducing the amount of time your screen stays lit after you've stopped interacting with your tablet is another good way of slowing battery drain. Return to the Settings > Display menu and select Sleep. Reducing this setting tells your tablet to turn off the screen after a set period of inactivity. The shorter the time you select, the less power your display will use. Try changing it to a setting of two minutes.
Step 4: Turn off unwanted connections
Wireless network technologies such as wi-fi and Bluetooth also consume quite a bit of power, so if you're not using them it's best to turn them off. This is especially true of Bluetooth, which many people never use on their tablet yet still leave turned on.
Go to Settings and select Bluetooth under the Wireless & Networks heading. Flick the switch to Off to disable Bluetooth.
If you're using your tablet on a long bus or train journey – or anywhere there's no wi-fi reception, you should also turn off wi-fi to save power. Open Settings and switch the wi-fi toggle switch to Off.
Step 5: Avoid using live wallpapers and widgets
Android's Live Wallpapers and Widgets require processing and graphics power to run so put extra drain on your battery. It's a relatively minor amount, but if you do want to absolutely maximise your tablet's battery life you may want to get rid of them.
Delete widgets from your homescreen by tapping and holding on them before swiping them up to the Remove icon. To change your wallpaper, tap and hold on an empty part of your homescreen and choose Wallpaper from the pop-up menu.
Step 6: Fully discharge the battery
The lithium ion batteries used in almost all Android tablets don't suffer the over-charging problems of older Ni-Cad batteries, so they don’t always need to be run down completely to stay at their best. However, to keep the battery's power meter correctly calibrated it's still a good idea to let your tablet run out of battery power after every 30 or so charges.
Step 7: Turn off Auto-sync
There are various apps and services on your tablet that automatically sync data with online servers, for storing contact information, providing Facebook alerts and sending email to your tablet. These syncing processes can drain power, especially if they’re pulling in a lot of information.
You can see which accounts are set up to auto-sync by opening Settings and choosing Accounts and Sync. If there are any you don’t want or need to sync in the background just tap on their name and untick the Sync option.
