What software version do you have installed (some later versions should have improved the situation).
Unfortunately the support is overloaded with work and still has a huge backlog, but they recently hired new staff, so hopefully the situation should improve soon.
The fairphone support consists of four people who are responsible for all support requests throughout Europe. When you submitted your first ticket, you will have received an e-mail in which they ask you to be patient, because a lot of requests have to be processed at the time and that you please do not send mulitple tickets for the same issue. So when you write [quote=“Guenhael, post:1, topic:20499”]
the fairphone support to which I posted several requests about that problem

you probably did not read that e-mail or just didn’t care.
I can understand that it’s hard to just sit there and wait for an answer, but Fairphone cannot afford 200 support employees doing nothing but answering support requests. It’s what you get if you are one of 100,000+ customer of a small startup company. I am in the same situation, I am also waiting for my ticket to be answered and I guess there are many others. Be patient and ask the community for help before you rush the support with several identical tickets.
As for your problem, you might also consider a battery reset:
When you deliberately drain your battery to its very bottom so the phone turns off automatically and then plug it in, you might actually get it charging (given the charger is not somehow broken).
