I have a 2.5 years old FP2, that was working fairly normally (though battery life started to get shorter, but nothing unusual after that time). Then yesterday night I couldn’t charge the battery anymore. I tried 4 cables on AC or PC, no charge. With a friend who also owns a FP2, I swapped battery, to check if mine was faulty. I couldn’t charge his battery either. His phone couldn’t charge mine. So my battery is probably dead, but it’s not the only problem. Then I remembered I had an old bottom module with a defective microphone. So I replaced my bottom module with the old one, which had no charge problems. I still couldn’t charge my friend’s battery.
I bought a new battery and bottom module, but with the tests I performed, I have only little hope that changing both would work.
When troubleshooting, I could enter the Logo-blink-vibrate cycle. I can use my phone when connected to a charger, even when the battery is 0%, but of course it shuts down as soon as I unplug. I tried removing SD and SIM card with no success. The memory use is about 60% and no app seems to drain the battery. The area above the battery starts to get hot when I attempted to charge.
Does anyone have any idea what could be wrong ? I’ll update as soon as I get the replacement parts, but meanwhile I worry it will not solve my problem, and I wouldn’t want to damage the new parts if something in my phone is wrong.
