I have a FP1(U) since summer '14. I had it repaired once under warranty (for unrelated issues). In March '17, I ordered a replacement battery since I suddenly had had to charge it significantly more frequently (a charge used to last a few/several days, then it swiftly changed to needing to be charged every day). It got better but didn’t really solve it, but I could live with it.
About a week ago, charging started to take about half a day, and the percentage didn’t show accurately (when I un- and replugged immediately, it would jump up some points). I tried the hack where you let it charge sans battery for some time (I did about an hour), then add the battery and let it charge completely before turning it on. It helped a little, in that the charge didn’t drop as rapidly as before, but that barely lasted a day. After that, I plugged it in again normally, but the most I got out of it were 6% after charging it all night and most of the following day. I turned it on, and for a few minutes it worked okay. The charger only works if held in certain angles (usually not an issue), and it “unplugged” for a split second, making it go down to 5%. It happened again, it jumped to 3%. My charger stayed plugged in (and the indicative light on) but my phone went down to 0% and shut itself off.
Now it doesn’t charge at all anymore. Meaning when I plug it in, absolutely nothing happens.
So! How do I fix this? What is wrong? Aside from the charge it works fine, occasionally it freezes for <1min but nothing significant.
I’ve searched this forum but haven’t seen this one before; if you have, please link me
EDIT: My charger works fine, I used it on a different phone with no issues.
