If the power consumption of the mobile phone is high and the standby time is short, it may be related to the operation of the mobile phone or the battery. We suggest that you try the following actions to reduce battery consumption: 1. When the device is not in use, you can switch to sleep mode by pressing the power button. 2. Turn on the power saving mode: Settings-(General)-Power saving mode-Slide on. 3. Close unnecessary applications through Task Manager (press and hold the Home button for two seconds). 4. Turn off the Bluetooth, location, push notification and other settings to extend the standby time without affecting the use. 5. Cancel the automatic synchronization function of the application. 6. Reduce the backlight time. 7. Turn down the brightness of the monitor. 8. Try to replace the original battery of the mobile phone if possible.
