Most Android phones do not have a Bluetooth Battery Level Indicator to show you how much battery power your connected Bluetooth device has left. Yet, it is a nifty feature that many of us will like to have. Having your Bluetooth headset or loudspeaker beep you to warn of a low battery at a critical time can be unsettling. But there is news that this feature will soon be built into the Android Open Source Project (AOSP).
Some smartphone brands with custom skins have implemented this for the convenience of their users. Such manufacturers include Samsung, LG, Huawei, and Xiaomi, among others. However, users of phones that run stock Android are unable to enjoy this feature.
Even when manufacturers are known for adding the Bluetooth Battery Level Indicator feature to their skins, the level of support and implementation varies. When paired with my LG Tone+ Bluetooth headset, the Samsung Galaxy A5 2017 does not display the headset’s battery level. Have a look:
There are 3rd party apps that offer the feature, but with varying levels of implementation and accuracy. Some of those apps work by add a (sometimes oversized) widget to your homescreen, using up valuable space.
Bluetooth Battery Level Indicator in Stock Android
This is why it is good news to read from XDA that “Google is preparing to add new APIs to “get remote device’s battery level” to AOSP. In other words, Android OS itself may soon get the capability for Bluetooth Battery Level Indicator baked in. That way, all Android smartphones get the feature out of the box, and manufacturers will no longer have to go out of their way to add it.
Once implemented in AOSP, lovers of stock Android smartphones will have a Bluetooth Battery Level Indicator on their devices without the need to install a 3rd party app. The question now is, How soon will this get to Android OS? There is no sure word yet. Perhaps in Android O? Or Android P? We do know that Google has documents stating that they are preparing to add it. It can’t come soon enough.
