How to boost smartphone’s battery life

Here are some  tips to boost the battery life of your smartphones and tablets.

Battery Doctor
This free app is available for iOS and Android. It shows which apps are consuming more battery and the remaining battery time of the device. The Android app also lets you do one-touch optimization of the battery.d Portronics Limebox (Rs 8,499) are two Android media players that are already available in India.


Carat is available for both Android as well as iOS and shows how much power each running app is consuming. After a week’s usage, it starts giving recommendations on phone usage to improve battery life.

 Use a black (or very dark) wallpaper

If your phone uses an AMOLED display—many popular Android devices do, though the iPhone notably does not—each pixel on the screen takes a little bit of power to “light up.” As such, the more black pixels you can get on your screen, the better. Set a dark wallpaper as your default, and try using dark themes on apps when possible.

Brightness level

Display is one of the biggest battery drainers on a phone. Instead of opting for automatic brightness in settings, manually set it to 40-50% in order to conserve battery.


Keep the phone and tablet’s Wi-Fi, Bluetooth, GPS, NFC and 3G connectivity switched off when not required.

Uninstall apps

Various apps run background processes that constantly consume battery. If you are not using a particular app, it’s better to uninstall it.

Watch for push notifications

How much battery life is drained by push notifications—those app-specific messages that pop up on your lock screen from time to time? That’s up for debate, but consider this: Each time your phone receives a notification from the network, it lights up and, depending on your settings, vibrates or makes a noise, too. That all takes a toll on your battery, especially if you receive a lot of updates. Toggle push notification options in your settings screen or within the apps themselves to remove all but the vital stuff.

Turn Off Bluetooth

No matter now much you love using Bluetooth in the car or with your hands-free headset, the extra radio is constantly listening for signals from the outside world. When you aren’t in your car, or when you aren’t expecting a call that you’ll want to take via a headset, turn off the Bluetooth radio. (Besides, walking around with a Bluetooth headset in your ear when you’re not actually on a call doesn’t do anything positive for your street cred anyway.) By turning off Bluetooth when you’re not using it, you can add an hour or more to your phone’s battery life.

Haptic feedback

The vibrating feedback from the phone every time the touchscreen is used might feel nice, but switching it off saves battery life.
