9 Tips to Boost Your Android Phone's Battery Life

Today's Android phones pack big, bright screens and high-end features that suck plenty of power. Here's how to squeeze the most juice out of your battery.

There are a number of factors that contribute to poor battery life on your Android phone. Thinner bodies, brighter screens, faster processors, more background software, and speedier internet connections all take their toll on phone batteries, but manufacturers are also incorporating more powerful batteries to compensate.

The Google Pixel 6 Pro has a 5,003mAh battery that can last for over 22 hours. Samsung's line of Galaxy phones can last anywhere between 11 and 13 hours, depending on the model. Still, there are ways to get more out of any phone.

Menu settings will differ based on which phone you're using; in this story, we used a Samsung Galaxy S 20 FE running Android 11. But all Android devices should have similar features. With this caveat in mind, here are some ways to improve the battery life on your Android phone.

1. Turn On Power Saving Mode

Think you're going to be stuck in a situation where you need your phone battery to last longer than it normally does? Switch your phone into power saver mode, which automatically cuts back on functions that may eat battery life. On our test device, we opened Settings > Battery and device care, then tapped the Battery entry.

Below the battery usage chart, we enabled Power saving mode to immediately limit networking, syncing, and location services, and turn down the screen's refresh rate. However, by tapping Power saving mode, we could further customize the feature by turning off the Always on Display, limiting CPU speed to 70%, or decreasing brightness by 10% in order to save even more battery life.

For maximum power-saving, the Limit apps and Home screen option enables only selected apps and limits all background activity when power saving mode is turned on. For older versions of Android, you may be offered multiple power saving mode presets, each with a different balance between performance and battery life.

2. Airplane Mode Is Your Friend

Sending and receiving wireless signals can strain your phone's battery, so consider turning on Airplane mode whenever you don't need to use your network data. Your easiest option: open the pull-down shade and tap the Airplane mode button to instantly disconnect your phone from Wi-Fi, disable Bluetooth, and turn off mobile data. Tap it again to restore access.

3. Your Screen Is Too Bright

Smartphone screens are big and bright, but they're also battery hogs. You probably don't need your device turned up to the brightest setting. Go into your Display settings and turn down the brightness on the screen. You can also open the pull-down screen and control the brightness from there. While you're at it, consider disabling auto brightness. This feature adjusts based on your perceived needs but can also raise the brightness of your display higher than it needs to be. Turn off the switch next to Adaptive brightness and your eyes (and battery) will thank you.
