What should I do if Samsung note3 uses electricity quickly?

If the standby time of the mobile phone is short and the power consumption is high, I suggest you try the following methods: 1. Manually end unnecessary programs in the background. 2. Turn on the power saving mode. 3. Bluetooth, NFC and other functions are recommended to be turned off when not in use. 4. Cancel the application automatic synchronization function. 5. Some machines support intelligent manager: enter the intelligent manager to close applications that don't need to run automatically (it is recommended to set instant messaging software such as WeChat and QQ to "On"); Check whether there is abnormal power consumption of software. If yes, it is recommended to uninstall and delete. 6. Some machine intelligent managers support setting application permissions and closing unnecessary program permissions. If the problem still exists after the above operation, please bring the purchase invoice, maintenance card and machine to the Samsung service center for professional after-sales engineers to help with the inspection.
