I modified the launcher to display battery level in percentages next to the time. Here’s a step by step instruction:
- Navigate to ~/launcher/sys.py/UI
- Open title_bar.py
- Replace the contents with the contents from here: https://pastebin.com/1BuMuk0e
The only downside is that the battery level updates only when the screen updates, i.e. if move the selection, or plug in the charger. If you leave the device untouched, the level won’t update while idle (it’s just the way the Launcher is written).
