There are some software on the market that can display Bluetooth power, but the prerequisite is that the Bluetooth hardware itself supports this function.For example, de.battery.widget_2.apk can display the power of the Bluetooth headset, provided that the Bluetooth headset itself supports the return of power information.However, most earphones do not have this function.
It is worth noting that the Bluetooth protocol itself does not include the power display function.This function can only be realized when the manufacturer installs corresponding chips in the product design and opens the data interface to the mobile phone for reading.However, due to increased costs, compatibility issues and other factors, it cannot be achieved in many cases.
In addition, it is worth mentioning that Miui, the Xiaomi mobile phone system, comes with the Bluetooth device power display function, so it does not need to install software separately to achieve this function.
It depends on whether the Bluetooth headset supports the display of power. Of course, the headset you bought originally can.Your question proves that it is a Bluetooth headset and has nothing to do with mobile phones.As long as the Bluetooth headset can recognize the power
There are two ways to display the battery level of the Bluetooth headset on the mobile phone. One is the support of the Bluetooth headset, and the other is the support of the mobile phone system.I think r11 plus does not support the display of face and headphone power
