How to display battery status in ios/android settings app?

Hello everyone, we are developing a heart hare accessory for the phone and we want to show the battery status directly on the phone. I found it can show up in the Windows settings and how can we do to show up on android or ios?

Hello,

As it appears in Windows, I assume you're using Bluetooth Service to expose battery level, not a custom service.

On Android it depends on the app. Settings app, which includes Bluetooth settings, is like any other app. It's up to the developers to decide what to show. It will differ between different manufacturers, which have their own Settings apps. 

iOS doesn't display it in settings, as far as I know. That may of course change in the future, but unlikely.

The small issue with displaying battery level in settings is that a device may have number of Battery Services, e.g. one for each battery they contain. Settings app would have to either display just one, or handle it some other way. It's easier not to display as most devices have companion app either way, which may display such data.
