I already wrote it yesterday in the main thread, don't install beta 1 of iOS 26 if you don't have a real battery from Apple. I've already seen a few posts on the internet yesterday that have the same problem (also here).
The battery level stays at 1% and the battery health is displayed at 0%. I was awake for a long time and tried a few things but nothing helped except DFU mode and a full reset.
Be careful in any case and stay away from the beta.
Supposedly it also happens with real Apple batteries but not that often.
