I know this looks a bit like some other threads, but also kind of different!
I have recently received my second replacement Fairphone 2 (the previous two all had different severe problems and had to be replaced, how is quality control handled by this company!!! I’m really starting to lose faith… all the waste that’s created negates whatever noble goals the FP is supposed to have!), and the battery that came with this replacement charges fine both when the phone is on and off.
However, I have an extra FP2 battery. When I put this in, the phone refuses to boot. I thought maybe this battery is fully discharged so I plugged the phone into my charger. But now the red LED lights up for about 1.5 seconds, followed by the black background Fairphone logo for another 1 second, then the phone turns completely off, and the loop repeats…
I have tried multiple different combinations of chargers and cables, and still only one battery works and the other doesn’t. What is wrong??? Thanks for your help.
