Why does my phone sometimes just turns off itself?

"I have to open my phone several times a day in order to restart it. Sometimes it even starts an update while rebooting the phone that takes about 15-20 minutes. This is very annoying especially if you are on the road and in need of google maps and so on.

Also the bumper starts to break due to the many times I need to do a forced reboot by removing the battery for a few seconds.

I really tried to spread the word about fairphone, but there is no chance to even hide the shut downs in front of friends since it happens in the middle of showing them something on your phone. I am still about to convince myself from this being an actual great product, but sometimes it is really hard when you are close to throw it out of the window."

"I have had this problem too. The phone seems to get stuck into thinking that the battery is very low, even though it isn't - hence it keeps shutting down.

What seems to sort it out is removing the battery for 10 mins (i.e. longer time) and then replacing it and fully charging it."

Have you heard about the "piece of paper/card" trick? Some Fairphone 2 have batteries that are slightly too small and so any movement causes the battery to temporarily disconnet. So put a small (0.5cm) piece of paper at the bottom of the battery to keep it firmly in place.
