1. Turn On Power Saving Mode
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. When not needed networks turn on Airplane mode
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. Use low brightness
4. Let Your Screen Turn Off

6. Try Dark Mode With the Right Screen
If you have a phone with an OLED or AMOLED display, it means the phone actually turns off the pixels that are displaying black, so you're saving some battery when all those bright white panels have now gone dark. According to iFixit, you could be saving as much as an hour of battery life by switching on dark mode.
Some phones have dark mode in Android 9 (Pie), but it wasn't until the release of Android 10 that all phones received the option. Open the pull-down shade and tap Dark Mode to turn it on and off. Otherwise, open your phone's Display settings to make the choice. You can also tap Dark mode settings to schedule when dark mode should go on.
7. Take Control of Your AppsApps continue to run in the background even when you aren't using them. This will, of course, eat up data and battery life over time. You can put unused apps to sleep under Battery or App Power Management settings. Choose Background usage limits and enable Put unused apps to sleep to prevent apps from wasting your battery life.
You can go a step further and manually tell your phone to put certain apps to sleep. Select Sleeping apps or Deep sleeping apps, then tap the plus (+) icon and add your app to the list. Keep in mind that sleeping apps will only receive updates occasionally and deep sleeping apps will not work unless they are in use, so updates may be delayed.
It's a good idea to periodically check on the apps that are draining your battery the quickest to see if there are any outliers you can delete or disable. You can view this information under battery usage in Settings, then decide which apps should be allowed to run in the background and which should be turned off when not in use.
8. Dumb Down Your Phone
9. Automate the Process
You can also use Google Assistant and turn phone settings into programmable routines. Open Google Assistant, tap your profile icon and select Routines to create new commands. For example, you could set it up so that the phone will prompt you to turn on power saving mode when you tell Google you're leaving the house or turn on Airplane Mode when you're home.
Select a routine (or tap + to create a new one) then tap Add action. While there are many preset actions, for our purposes, select Try adding your own at the bottom of the list. Basically, if it's a command you can give Google Assistant, type it in and you can turn it into a routine.
