Bluetooth when not in use.

Manage your apps
- Battery optimization helps extend battery standby time. See Battery optimization for apps.
- Install the latest software and application updates. Updates sometimes include battery performance improvements.
- Uninstall or disable apps that you never use.
Many apps run processes or sync data in the background even when you're not using them. If there are apps that you don't need anymore, uninstall them.
If an app came preloaded and can't be uninstalled, disabling the app can still prevent it from continuously running or syncing data. See
Disabling an app.
Limit background data and sync

- In Settings, tap
Accounts & sync and check what types of data are being synced in your online accounts. When the battery is starting to run low, temporarily disable syncing some data.
- If you have many email accounts, consider prolonging the sync time of some accounts.

Play Store, tap
