1. Lower the brightness, turn on sleep
This is, perhaps, the most common battery-saving tip that applies to any device with a screen. Keep your screen’s brightness at 50% or lower and your Android phone will last longer. You can adjust the brightness by bringing down the notification shade with a two-finger swipe down (sometimes it’s a single swipe) from the top menu bar or by going into Settings > Display > Brightness level. And while you’re at it, you may as well disable Auto Brightness (called Adaptive brightness on Android 5.0 “Lollipop”).
The other feature within the Display settings that you can adjust is the screen’s sleep time, the amount of time the screen will wait while it’s inactive before switching off. It’s usually set to 30 seconds, but we recommend setting it to the quickest (15 seconds or less).
2. Figure out the power hog
Suspended apps — apps that are minimized but not closed — can still consume a lot of power without your knowledge. Luckily, Android has a built-in battery monitor. Go to Settings > Battery and you’ll be able to see which apps are the biggest offenders. Now, you’ll know which apps to avoid using when you know you’re going to be out all day.

4. Use darker wallpapers
There two main types of smartphone displays: LCD and AMOLED. LCD uses a backlighting system that illuminates every pixel on the display. AMOLED displays, however, have pixels that are individually lit; a pixel that turns into a color is lit, and thus, uses power. A pixel that remains black, is not lit and doesn’t use any power. If your Android phone uses an AMOLED display (just about all of Samsung’s do), you can use a darker or all-black wallpaper to make your phone more power-efficient.
5. Turn off GPS/location tracking
Many apps like Google Maps, Swarm and Yelp use your location to provide real-time location data, but if you rarely use location-based apps or use them sparingly, it would be wise to leave the GPS off. Some phones have a GPS (called “location” on Lollipop) button accessible in the notification shade. Otherwise, you can turn off location tracking by going into Settings > Location
