Help Fairphone 1

Today my FP1 showed a very strange behaviour after reboots:

  1. phone was charging and I rebooted: battery status jumped from approx 65% to 95% and phone stopped charging at 100%:

  2. Rebooted the phone after a few hours again and the status dropped from 70% to 25%:

Does anyone had such behaviour? I guess my second FP1 battery is starting to die… :frowning:

I will try a battery reset an keep you updated :wink:

My second one is also showing such a behaviour… Have you seen this thread? There are batteries from the old manufacturer “Fenghua” and from the new one “3Sun/Maxell”. Do you have one from the former?
