When I charge my Fairphone on a 3 A charger, then it doesn’t get hot but warm. But mostly I don’t use my phone while charging. So if you use your phone and the screen is on and you charge it fast, then it might get hot because the screen also adds to the raise of the temperature.
I have the same issue. Today it turned off two times in my pocket. I had this issue since I bought the fairphone 6 in june 2025.
Again. My Fairphone 6 was lying on my desk for an hour or so without using. When I tried to use it, it was off. Turned it on manually. 
Interesting: I have my clock set to manual (for reasons). Every time this happens, the clock is far far far in the past. Next time I should check if it is always the same time in the past (probably). I hope I won’t forget to check that in roughly a month (expected next shutdown).
As indicated earlier by Meaghan it’s important to contact FP Support about this if you haven’t already. Next time it happens check the clock but I suggest you also take a bug report which will save waiting for a month if they ask for one!
I’m experiencing the same issue with the same model
Hi everyone,
I’m experiencing the same issue that’s been discussed here. My device keeps rebooting spontaneously, and it seems to be linked to the Wi‑Fi connection. When I turn Wi‑Fi off, the random reboots stop. After switching the device to my 2.4 GHz Wi‑Fi band, the problem appears to be resolved.
Has anyone else noticed a correlation between the Wi‑Fi driver crashes and the Wi‑Fi band being used? Any insights or additional troubleshooting steps would be greatly appreciated.
Thanks!
Hi everyone, yesterday I got myself a used FP6, since then two times spontaneously powered off, never experienced with my other FP6.
I’m wondering, do you have new insights on that, is it a HW issue? Is there a resolution yet? I’m running Android 16. Thanks a lot- Martin.
how do I take a bug report? I know how to get it inside of Signal Messenger for example, but how does it work in this case for the whole phone? @OldRoutard
Btw: my fairphone 6 shut itself off again three days ago. again with the flash on. At least a relatively long time since this happened last time.
i did a proposed android update afterwards. Has probably nothing to do with each other.
Hi nrtd,
You can take an extract of logs using adb but as it’s probably a good idea to do it as soon as you’ve re-started the phone, best is to use Developer options > Bug report. Choose “Full report”. You’ll then be in a position to offer it alongside your ticket with Support. You’ll also find the option “Bug report shortcut” which makes it even quicker. Don’t forget that a full report can contain confidential information about your use of the phone.
I have myself experienced this twice, both times on the same day, since receiving the phone last July. The phone was just in a bag over my shoulder, no special reason why it should have happened, that I could determine.
@taco1978 This topic is about a problem where the phone just turns off. It’s not about reboots, of whatever kind. I suggest you search the forum for topics that are closer to your problem, and we can arrange to move your post.
Thanks !
