The old anxieties about processor speed or how much RAM a device has have been replaced by worries about how long the battery in a device will last. While modern Android smartphones and tablets promise hours of use from the battery between recharges, the truth can be somewhat disappointing.
What follows is a series of tips to help you get the most out of the battery in your Android smartphone or tablet. Feel free to pick and choose the tips you think will help the most – there's certainly no need to do everything listed here!
Whether you're running stock Android on a Nexus or a customized version on a Galaxy S5, here you will find simple tips and tweaks that will help you to understand more about what's going on with your device and how to get you more battery life.
See what's going where
Knowledge is power, so the first thing to do is to see what's sucking at your battery the hardest.
To do this go to Settings > Battery to get a breakdown. From here you'll be presented with a list of features and applications that are draining your battery the hardest, and if you see a feature or service sucking up a lot of power, you can shut it off.
Reduce screen brightness
One of the biggest draws on the battery will be the device's screen. The brighter the screen, the more power it takes. Therefore, by cutting down on the brightness of the screen you can get more time out of your battery.
Go to Settings > Display > Brightness (or swipe down from the top-right and click on Brightness) and turn down the display to a point where it's just bright enough for you.
While you're there, you can disable auto brightness.
