Dear Samsung users, if the standby time of the mobile phone is short and the power consumption is high, it may be related to the operation of the mobile phone or the battery. I suggest you try the following operations 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-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. If the problem still exists, please take the purchase invoice, maintenance card and machine to the Samsung service center, and the professional after-sales engineer will help you test it.
