Phone won't charge, stops recognizing USB-C randomly

Help Fairphone 5
1

Hello,

I have a problem charging my battery and I suspect it’s a software issue rather than a hardware one.

I’ve had the FP5 since may this year and pretty early on I had trouble charging the phone. Sometimes it worked, sometimes it didn’t. This problem magically fixed itself as I didn’t change cables or components.
Unfortunately it stopped working again earlier this month. This time for good, no matter the cable or whether it’s connected to pc/powerbank. So I ordered a new USB-C port and replaced the old one. This seemed to fix the issue for several days, after that the charger randomly stopped working again (again, sometimes it worked, sometimes it didn’t) and now it seems to be completely broken again.

What could be the problem? So far I’ve tried:
3 different cables
3 different methods (normal/powerbank/pc)
2 different batteries
2 different USB ports (both seem to look okay)

Everything’s updated. Hope someone can help me.

At this point the culprit HAS to be the charging-controller or something close to it imo, as far as I know it is on the mainboard. If it is a software-Issue, the phone probably would not have the same charging-issue while being turned off.

Hi, had a similar issue with my fp5 last week (first it lost contact to my (physical) SIM card, then USB-C). Had a good support chat on fp support site (I purchased the phone at fp online shop) and they proposed to send it to their repair center. Waiting for return of the repair fp5…
Hope that helps.
Good luck

Hello BP58, I have a similar charging issue. With a ‘turn off - turn on’ of the FP5 it works.
I am very interested in the results of the repair centre. Please post it. Regards, Pete
