How To Improve Android Battery Life On Tablet Computers
If you own an Android powered tablet computer, you might be interested in the tips that I’m going to be sharing with you today on how to improve Android battery life.
First things first, what I’m about to tell you is really simple. You don’t have to be a computer expert to make the changes that I’m about to suggest. Just apply these simple tips and you’ll be on your way to better performance from your android powered tablet computer in no time.
The screenshots that I’ll be including in this article are from my Samsung Galaxy Tab 10.1 and it’s running on Android Honeycomb so the menus might be different on your device but the principles are all the same regardless of the version of Android that you’re running.
- Turn off the radios when you don’t need them. If you’re wondering what the heck I’m talking about radios for, let me explain. For the purpose of this article when I refer to “radio”, I’m talking about the Wi-Fi receiver, GPS receiver, and Bluetooth. If you have Wi-Fi enabled when you are in the park and reading a book on your tablet computer, your device will be constantly searching for a Wi-Fi signal that it can connect to. The same holds true for GPS and Bluetooth. Disable these radios when you don’t need them and they won’t be sucking down your battery power.
- Turn off live wallpaper. The psychedelic moving graphics on live wallpaper are fun to look at for a minute but they’re not really helpful to you in anyway and having live wallpapers installed puts an unnecessary load on your battery.
- Use a dark themed wallpaper. The display on your Android tablet will use more power when it has white or light colored wallpaper running. On my tablet, I have the wallpaper set to nothing but a black background which doesn’t require hardly any power for my tablet to display. I used a free app called No Wallpaper that you can get in the Android Market to do this.
- Ditch the auto screen brightness setting. This setting is intended to guess what your preference will be when it comes to how bright your screen should be set to but it usually turns the brightness up to high in my opinion. The brighter you have your device’s screen set, the more power it will consume so turn it down manually to the lowest setting for whatever the conditions are when you are using your tablet and your battery will last longer between charges.
- Reduce the length of time that needs to pass before the screen will timeout and turn off. If you have the screen timeout setting set too long and you put your Android tablet computer down to go answer the door, your device will keep sucking power until the screen times out. It’s much better to have to wake your screen up from time to time than it is to waste power running the display when you’re not using your tablet.
- Turn off “auto synching”. One of the cool things about tablet computer apps is that they can automatically connect to the Internet and update the data that your app needs. For example, your tablet will check every so often to see if you have any new emails and if you do, it will automatically download them and notify you. The problem arises when every app on your device wants to constantly connect and check for new data. Do you really need your apps to be checking for new mail and weather updates every five minutes? Probably not and if you turn off auto synching or at least increase the length of time between when an app checks for new data, your battery will last longer.
- Keep your firmware updated. I own an HTC Thunderbolt which is an Android Powered smartphone and just the other day I happened to check to see if there was a new version of the firmware for my device. I was more than a little happy when I discovered that updating the software on my phone upgraded the OS from FroYo to Gingerbread. This new version of the Android OS seems to handle power management much better because my battery is lasting a lot longer between charges!
There you have it. Apply these simple tricks and the “foo-foo” features of the Android OS won’t feast on your battery power. Most of us would rather the battery last longer than be able to be entertained by the “eye candy” features like live wallpaper. Some of the other settings I suggested that you modify should be tweaked to accommodate your personal use habits.
