Battery Usage Blank

dregrinfuces

I've got a new Pixel 9a (4 days old) running GOS 20250417. Even though I've charge the phone to 100% several times now, under Settings > Battery > Battery Usage, there's no Battery Usage by app or system displayed. All it says is "Battery usage data will be available in a few hours once fully charged." Does it take a while to understand the battery enough to display that information? Or, have I missed some kind of configuration item for it?

dregrinfuces I have had this behavior for weeks if not months. I have my phone set on reboot to BFU after 30 minutes, perhaps this causes my blank battery graphs... Whatever the cause I have given up checking for the present.

Same behaviour here. Have not found out how to activate battery usage.

I'd forgotten the Auto Reboot setting. But, mine was at the default 18 hours. So, I don't think that's causing it. I changed it to 24 hours. I guess I'll head over to the GOS Github page and report the issue with Battery Usage.

Here's a link to an old report on the same problem which I piggy-backed on:
