I really liked the System UI Tuner feature in Android 7.1.2 that allowed for Battery% to be indicated in the battery icon on the notification shade.
It's not required in the UI Tuner because the option to show or hide the battery percentage is now available under settings > battery.
Welshpaul, the option for showing battery percent is not answering the OP question. yes you can show battery percent, but not inside the battery icon, you either get the battery icon or both.
It looks like you're new here. If you want to get involved, click one of these buttons!
