How to turn off the power-off tone of iphone?

The low battery tone is a function of Apple's mobile phone and cannot be turned off in the settings. If you don't want to hear the sound of low battery, you can operate as follows:

1. If you want to mute photos in non-mute mode, you need to jailbreak the phone, as shown in the figure.

2. After the mobile phone is jailbroken, open Cydia to enter, as shown in the figure.

3. In the search, search and find a plug-in named NoLowPowerAlert to install. As long as the plug-in is installed after iPhone jailbreak, the low-volume prompt tone will not be lost, as shown in the figure.

4. After the installation is completed, restart the springboard and turn off the annoying power prompt tone on the iPhone, as shown in the figure.
