One of the biggest problems with Android is its lacklustre battery life. Compared to iOS and Windows Phone, Google's mobile platform saps battery at a faster rate. Many Android phones don't even last from dawn till dusk. There's no silver bullet to solve this problem. However, by altering a few settings, you can make your device's juice last a little longer. Here's how to go on about it:
Lower The Screen Brightness Cranking up the brightness improves the screen readability. However, high screen brightness can drain your phone's battery like anything. So if you want your phone's battery to last longer, go to Settings, and set the brightness to the lowest value you're comfortable with. If your phone has an AMOLED screen, use a black background. AMOLED, being an emissive type screen, can switch off pixels to produce deep blacks. In effect, the phone requires relatively less juice to power the display. In addition to this, shorten your phone's screen timeout time to minimum.
De-Activate Live Wallpapers And Useless Widgets Unique to Android, the Live Wallpapers look fancy. However, rendering all these real-time animations take a toll on the battery life. If you want to conserve the phone's battery, do not use the live wallpapers. Similarly, widgets continuously consume your phone's battery. However, some of the widgets are useful as they serve you the information right on the homescreen. So, what you need to do is remove the widgets that you don't really require.
Use Wi-Fi Instead Of 3G To make the most of your smartphone, it needs to be connected to Internet all the time. While 3G offers excellent browsing and download speeds, it eats-up battery rapidly. Things get worse, when the 3G signal reception is weak and flaky. On the other hand, in recent smartphones, Wi-Fi uses less battery compared to 3G. So whenever available, make it a point to choose Wi-Fi over 3G data. Plus, it will also help you save money on data charges.
Keep GPS And Bluetooth Off Smartphones these days come with a multiple wireless radios including Bluetooth, GPS, NFC, and Wi-Fi. Save for Wi-Fi, you don't require these connectivity options most of the times. Therefore, it's advisable to switch them off unless you're actually using these features. On stock Android, you can quickly do so by pulling down notification bar and then selecting the Settings Panel. If not all, at least keep the GPS and Bluetooth radios off as these two connectivity options drain the battery at a rapid pace.
Keep A Check On Background Processes From the multitasking menu, clear the list of recently used apps. You don't want to keep a heavy game run in the background as it can hurt your phone's battery life real bad. Also, check the list of services running in the background. If you see any unnecessary process running there, stop it. If you're unsure about a certain service, click on it to find more information regarding it.
