I recently baught a new fairphone and was using it for about a day and noticed suddenly it was off and would not turn on. I did not get any low power notifications and it shouldnt have been on long enough today to die. Holding the power button has zero reaction, it does not attempt to start or warn low power. When plugged it it flashes the fairphone splashscreen for less then a second and then nothing further. It does not indicate further if its charging.
Is there a way to test different components to see if its the battery, port or otherwise? Thanks.
