Since a few days my FP3 charges veeeeeerrrry slowly (20% in 8 hours). It is kinda weird because the charging light is on, but battery sign on the right op doesn’t show that is charging. Also my FP3 wont buzz if I put in the charger, which it normally does.
Things I have already tried:
different chargers / cables
pulling out the battery for hours and putting it back in
cleaning the USB connector
I don’t know if the problem is the USB connector, because it is kinda connecting as the light is on? Maybe it has something to do with the battery, but that would be kinda weird as well since it was working perfectly fine until 4 days ago.
Thank you for your answer! I read the topic you suggested and indeed lots of people experience the same issue. I removed the bottom module and cleaned all the contacts, but without any result. The phone is still in a reboot loop when i charge it while it is off.
I am thinking of buying a new bottom module, however they are sold out everywhere . Anybody any tips of actions i can perform to repair my Fairphone 3
Fairphone expects the bottom module for the Fairphone 3 to be on sale again in 5-6 weeks.
Perhaps you can use an external charging device to charge your battery.
In this topic you find a recommandation for an external universal charger.
Did you try different plugs as well?
You could try monitoring the charge with an app such as AccuBattery or Ampere (Play Store) or BatteryBotPro (F-Droid) to see how it charges. If rhe charging current is below 0.5A (or even negative when the screen is on), it indicates indeed the phone is charging too slowly.
