I have got some issues recently with the battery of my FP3+ (not in guarantee anymore) not getting the charge and when my phone when off it is now impossible to switch it on and also the battery does not charge. It is kind of start to switch on but stops at the screen with Fairphone and then off again … when I have it on charge. I have tried to open and remove battery, sim card, unscrew as well but I could not unscrew all so I have put it back but cannot use it.
This morning, I have been to a repair shop and they have tester different things :
. Battery delivers 3,2V instead of 3,85V
. The same test with a multimeter on the connections where the battery is plugged gives 0V when no battery and same 3,2V with battery connected when the guy said to me it should deliver 5V
. Testing the charge was not concluant as well, so it just detect the charge but apart from a simili start with “Fairphone” appearing then it goes back and keep do that loop.
As a conclusion the guy said to me it’s either : the battery, the charging spot or the mother board.
Any imput from anybody on this ?
I was thinking of ordering battery and charging spot if possible … replace them and see how it goes !!
At 3.2V it may take the battery hours just to get going.
Do you have any LED colour, red would even be good.
The shop is a bit off with 5V, watch them :). The max voltage will be 4.4V as stated on the battery
Try new cables and chargers if you have any, even plugged into a PC USB A port will charge after a day 500mA max.
To repeat, when the voltage drops that low 3.2V it can be very difficult to charge, Persevere for some hours and do not ever turn the phone on to test. After some hours just press the power button quickly to see if you get a notification on the screen
It can be laborious as you may have to try different cables and chargers.
Following your advises, I have made few trials of charging … but no différences.
I have a red light flashing when it’s on charge but nothing happens except the phone try to start and then turn off …
Thanks for the angel maps and I have seen somebody in La Reunion island which is where I live but cannot get the email address to contact. It is opening a new window on my mac but no email address very clear, could you help ?
I think I am gonna order the batterie and I’ll see how it goes.
Thanks a lot,
Thanks amoun, but I tried that already … battery is 1% and doesn’t get the charge …
For the La Réunion angel thanks for following up.
I have ordered a battery, the slot for usb c charge and will check if that works. If not I will some spare parts to sell … but at least I would have tried !
Thanks for your help. I have changed the battery and the module for the charger USB-C and it works quite well. My phone still has some difficulties sometimes to take the charge so i have to reload and not touch at all the cable … so maybe there is a small connection issue inside the phone. I’ll try to de-assemble it again and spray with compresses air + special spray for connections.
