Apple's mobile phone consumes a lot of power, which can be improved with a few simple settings. You can look at my electricity consumption. The standby time is nearly 16 hours, the use time is nearly two and a half hours, and there is still 70% power.

Turn off the location service.

Settings-Privacy-Location Services-System Services (at the bottom) are turned off except for the last compass calibration. These are all useless things. If you don't turn it off, the mobile phone GPS will always send and receive data, which is very, very power-consuming.

Turn off automatic date and time

Settings-General-Date and Time. Turn off the automatic setting, otherwise the mobile phone terminal will always search your current location, and then automatically adjust the time according to the location. Although this is a very user-friendly function, we usually don't need it, and this is also very, very power-consuming! So that some FYs find that the standby time of their mobile phones is the same as the use time, and the culprit is it! )

Turn off the automatic transmission of diagnostic information.

Overview-About this machine-Diagnosis and dosage. If you choose not to send, this option will pop up when activated. Generally, you choose not to send. If you choose to send it automatically, it will automatically record the system problems in the use of the mobile phone, and then automatically send it to the Apple server. This is also the culprit of power consumption, so it is recommended to turn it off.

Turn off automatic brightness level.

Settings-brightness and paper. Turning off the automatic brightness level is also a very practical function, but I chose to turn it off.

Turn on restricted ad tracking

Open "Settings-General-About this machine-Restrict advertising tracking" in the advertisement.
