When reading, the battery charge will go from 100% to 70 or so in a couple of hours, and then say the battery is empty. If I connect an external powerbank, it goes on for a little while, but reports the powerbank as empty when there's still a lot of charge left. Has anyone else had a similar problem, and if so, did it help to replace the battery?
I've sometimes used it outside in -20 degrees C (when it's too cold to bike I've been reading while waiting for the bus), I guess that's not a good way to treat a battery that's meant for indoors use. Or the cause could be something else, of course. It worked fine for years before this happened.
I found another thread on battery problems on the same model, but it doesn't seem very similar:
