2. Turn off Bluetooth, NFC, GPS, synchronization, etc. in time when not in use, and the screen brightness should not be too bright.

3. Upgrade the mobile phone system to the latest version. Note: Please back up the data in the device before upgrading.

(1) On the standby page, click to select settings.

(2) Click to select System Update.

(3) Choose to download updates manually/download updates automatically (Software Update/System Update-Update).
