11 Tips to Boost Your Android Phone's Battery Life

1.Dump unnecessary home screen widgets
Just because they're sitting on the home screen, seemingly inactive, doesn't mean they're not consuming power. This goes for widgets that poll status updates in the backgrounds
2.Keep Wi-Fi on during sleep
If you have the choice between using Wi-Fi or cell signal, always choose Wi-Fi, all other things equal. Wi-Fi drains far less battery than cellular service. But in the Wi-Fi sleep mode the 3G cellular service will be on automatically, To turn it off, go to Setting > wifi > advanced > keep wifi on during sleep
3.Keep an eye on signal strength. 
If you're in an area with poor cellular coverage, the phone will work harder to latch onto a strong-enough signal. This has an adverse effect on battery life. it's worth popping the phone into Airplane mode if you don't need data or voice calls.
4.Shut down vibration
To produce the vibration effect, your device has to spin up a small vibration motor every time, which can be really draining on your battery.
5.APP killers suck battery rather than conserve it.
6.Reduce email, Twitter, and Facebook polling. 
Auto Synchronization uses background processes that can eat into both your mobile data use and battery life. Set your various messaging apps to "manual" for the polling or refresh frequency, and you'll instantly extend your device's battery life by a significant amount.
7.Turn unnecessary hardware radios off. 
Android keeps location-based apps resident in the background, and the constant drain on your battery will become noticeable, fast. If your phone has a power control widget, you can use it to quickly turn on/off GPS (the largest power drain), NFC, Wi-Fi, Bluetooth, and LTE.
8.Turn down the brightness and turn off Automatic Brightness. 
It's probably obvious at this point, but you'll be surprised by how much this one alone helps to improve battery life.

9.Keep an eye on apps that use data in the background.
Some apps, such as the Play Store and Gmail apps, continuously collect and send data in the background. You can restrict such background usage of data — per app — and your battery will be the happier for it.

10.Ditch live wallpapers
Yeah, that massive spiral galaxy slowly swirling in glowing tranquility looks great on display units, but in everyday life, these gorgeous backgrounds take processing power to animate.

11.Use a phone with good processor

Question about No9

In reply to: 11 Tips to Boost Your Android Phone's Battery Life

Hi Yoyo.

Thanks for your tips. Can you help me keep the eyes on apps that use data in background? How can I restrict background usage of data to save my battery?

Sorry I am new to Android mobile so I need to learn more about how to use it.

Bright Screens Kill Battery Life

In reply to: 11 Tips to Boost Your Android Phone's Battery Life

I like the list, but I would add one point that happens to be a constant mission I have:
Replace bright backgrounds with dark ones.

If you look at your battery usage odds are the largest drain will be "Display". Not only do bright app backgrounds drain the battery faster, they also cause eye strain, can keep you up at night, and, most importantly, in the world of AMOLED and Super AMOLED displays the pretty, bright objects can cause unwanted screen burn-in and color morphing over time. If you set the screen timeout to something over 5 minutes or watch videos with bright watermarks the burn-in and color morphing can settle in before you know it.
Using a browser with a night or reader mode can help and also lets you stand out with custom backgrounds. Nova Launcher, as well as other launcher apps allow you to customize some bright icons, such as the especially distracting Google bar. Icon packs are hit-or-miss as they can drain the battery for no good reason, but now you can set any app with any icon already stored on your device (for example, I changed my browser icon from the stock squirrel to the Chrome icon). Swapping out the apps you use most to a dark alternative will help save your eyes, the display over the life of the phone, and your battery life.

Currently I use:
NovaLauncher: UI lancher to customize folders, icons
UC Browser: customizable browser.
Textra: customizable texting app.
VLC Player: stable music and video player with dark menu option.
SwiftKey: customizable keyboard.
Waze: navigation with a customizable background and better reporting.
Jorte: Calendar app with customizable background and full suite of widgets.
