Another random observation (and I’m not nearly as techy as other contributors here). My FP2 battery seems to have been draining very fast, and in particular had drained overnight. I read the advice on the forums: (Battery problem at night, which is for FP1 but seemed relevant).
So I decided to try draining it right down. At 3pm today it was on battery saver, saying it had 1% and 4 mns left, but then didn’t move for 30 mns. It’s now 6.55pm and I’ve been listening to Spotify on my phone since then, and it’s still going strong. It sees that battery life may be fine but the battery indicator is faulty and has been giving false alarms.
Can I reset it?
