Fairphone 4 doesn't charge anymore

[Simone_Biagiotti]

Yesterday I wanted to charge my Fairphone 4 that was had around 15% of battery but plugging the USB cable the phone was not charging. I tried several different cable that are all working fine with other devices but the phone was not charging. The USB plug is clean inside and apparently nothing is broken.
Is there anything I can try before sending the phone to a repair center?
Thanks

Hi and welcome to the forum.

You may try charging slowly for half a day with the phone powered off, An old fashioned USB A to USB C that you can plug into a computer:

There’s lots you can read, but it does no harm to contact support as that can take time and be gruelling.

New FP4 won't boot / charge after battery discharge

I already read that you tried several chargers. But did you try a SLOW charger? As in 5V, only 1 amp or so. Probably an older one just sitting in a drawer and with usb-A plug. I have a tablet, that when drained to ‘power off’ wouldn’t charge with the charger I used before. Worse: it would say CHARGING then within seconds: POWERING UP Again a few seconds BATTERY LOW (or depleted?) SHUTTING DOWN Which it did. And repeat from ‘CHARGING’ The only way I could break that cycle was Use an…

FP4 does not charge

Hi there, I have an annoying problem: my FP4 will not charge. When I restart my phone, it charges again, but after a short time it does not charge anymore. Does not matter if slow or fast charging. I am using the original FP4 charger, and when I dial ##2886## while charging, the following test results come back: USB:ok Charging:NOK Current:NOK Current:0 uA The FP4 system is up to date. Has anyone had the same experience? Is this a software issue? Thanks a lot for the help!

Hi, thanks for your reply. Sorry for having been so quick in my message but I was struggling (and still am) in finding a solution.
What I have done, beside of course reading the similar problem in the forum, is trying to follow some of the instructions that seems to work to other people. More in detail:

1. Follow the debug instruction for USB cable (test failed - USB: unknow, Charging: unknown, Current: unknown)
2. Clean the USB connector
3. Remove the USB connector, clean the plastic cover (the one you need to remove before removing the connector) using alcool
4. Try to change the device overnight and see if the battery has somehow charged slowly (hadn’t)
5. Try a low power charger (I used it for about 5 hours), no result.
6. I also reboot the device several time, the only action I have not taken is reset to factory configuration.
   To be honest I have no idea of what I can try, the hardware seems fine meaning that there are no cracks that I could see.
   Should I try to replace some hardware or is there a way to test the hardware as well?
   Thanks
   Simone

5 hours may not be enough if the battery has ‘died’ it could take the best part of a day

The only part you can change is the USB C port.

After a conversation with Fairphone, my daughter bought a new USB port and all seems well. They are now refunding the cost.

Note: You have a warranty I imagine, so contact them with all the steps you have taken.
