A severe crashing and restarting story just started to happen to my Fairphone. To solve the problem I already did some speculations which mainly include the energy supply.
First let me explain my problem
Since I updated my Fairphone to Kola Nut and right before did the storage update my FP1 crashes quite often. The first time this occured was during the update to Kola Nut right after the Storage Update from 1.6. I was still doing the Kola Nut Update on recovery mode so I had to find the update on the SD-Card. While browsing the phone was suddenly showing the blue start screen without any text then went off again and started the blue screen. It flashed for a while on it’s own until I got impatient and started the recovery mode again with pressing the volume up and power button. I could then update and everything seemed to work fine for a few hours. But then, all of sudden the screen went black and restarted the phone. Without any warning this “restarting” happens quite often. Sometimes it just starts normally and I need to reenter my SIM-Pin and sometimes the process failes as described with the flashing screen forcing me to restart on recovery mode and select to reboot the system.
On my search for the cause of the problem I realised that every time after a crash and restart the battery level dropped severely.
So either a component of the phone which is causing the crash consumes a large amount of power right before it crashes or the battery itself can’t supply enough power to keep the FP running.
Another minor problem I recently discovered and saw more frequently was that the power button performes unpredictable with sometimes turning off the FP’s screen just as it should and probably every second time showing the shutdown menu where to select to either restart, shutdown or put the phone into Airplane mode. I’m very sure that I pressed the button for only a short time (t < 1s).
What do you reckon? Is the crashing and failing restart connected to the battery?
Thanks for your aid!
the screenshot shows my battery graph with one crash right at the beginning (about 95% battery level), one at the first drop of energy (85%) and one at the second drop (from 65% to 20%)
