1.Black wallpaper can save battery
If your phone has an AMOLED screen (like most Samsung devices), use a dark-colored background.
2 Use dark themes and settings
Using darker app backgrounds/themes and darker launcher themes will further prolong your battery life (but only if your device has an AMOLED screen).
3 Don't use adaptive/auto brightness
auto-brightness is usually way brighter than you really need.It's much better to manually set a super low brightness level.
4 A shorter screen timeout setting saves battery
Set your display's screen timeout to as short a time as is practical for you.
5 Turn off vibrate and haptic feedback to save battery
Switch off vibrate.It takes more power.Unless you really need that added awareness, turn off vibration alert.
6 Use lock screen notifications
This is because you can see your notifications at a glance without having to turn your whole screen on.
7 Only use original batteries
8 Set your ''Do Not Disturb'' or ''sleep'' schedule
Set ''sleep times'' or ''blocking mode'' to switch off Wi-Fi and mobile data when you don't need them.
9 Don't let your apps fall behind the times
Keep your apps updated. There's a reason developers constantly update apps, and many of these reasons are memory and battery optimizations.
10 Use your basic battery saving mode
11 Don't fall into the auto-sync trap.
Turn off auto-syncing for Google accounts. If you don't need every single Google account updated every fifteen minutes, just go into your Settings and Google account and turn off auto-sync for those apps you don't needconstantly updated.
12 Manually update apps when it's convenient for you.
13 Turn off Google hot words.
Stop your phone from always listening. Google's "Ok Google" voice searching is a fantastic and often very functional feature. The problem is that it can play havoc with your battery. Especially if you don't actually use it or only use it occasionally.
