Hi fairphone community, i have my FP3 for about a month now and use it a lot. Since about 3 days the phone started to shut itself down at about 55% battery. Which is obviously annoying. When I reboot it shuts down again after about 3 minutes. Eventough it is Winter outside this behaviour occurs in…

Hi Richard and welcome to our community forum. This is definitely something you should report to Fairphone Support (our forum here is almost exclusively run by users like you and me) at https://support.fairphone.com/hc/en-us/requests/new . I cannot recall that this (concerning an FP3) has been repor…

Thx. I gave it a shot and will let you know what they say.

Can you check the temperature reported by the battery sensor? I know the Ampere app (to show charging status of a phone) can display it, probably there are more apps for it.

My guess would be a faulty or miscalibrated battery temp sensor. This MUST be a warranty case and can actually be dangerous! If the temp sensor reports too low a temperature, at cold temps its merely a nuisance as the phone shuts down. But it would likely report too low temps as well if the phone i…

Ampere shows a battery reading of 28.4 C - this seems reasonable, I guess? [photo_2020-01-07_11-23-11] Update: These two screenshots were taken shortly after each other : 26.1 degrees, then seconds later the phone reboots. [01] [15]

Let’s hope not. This reminds me of the exploding Samsung Note 7. Good point, I will try to keep safe. I’m thinking it could be a compatibility issue with the apple charger, damaging the battery in some way, but I have no idea. In the meantime the phone did some restarts at over 90% battery level -…

Maybe the temperature sensor is having some sort of loose contact. In most Android phones, the battery sensor is actually inside the battery pack. That’s why the battery has 3 or more contacts. One is +, one is ground, and the others are to sensors - either analog (3 wires) or digital (for example …

The sensor is inside the battery for the FP1 and FP2 so I guess it is the same for the FP3 (which also has 3/4 pins, I seem to remember.) If it is not a loose contact, you should try it with a different battery. Maybe one of the #fairphoneangels near you has an FP3 to test, or an FP3 battery.

The loose battery explanation makes a lot of sense - I am a regular runner, and do like to bring my phone. I would have gone for a light IP67 FP3, if it was around, and was now trying to keep it as dry and protected as possible anyway, but did think bouncing would be alright. Back in the day when my…

[image] corvuscorax: if the battery contact is loose, that could explain flaky readings, especially on a digital sensor. So some of the times the sensor reads out fine, but every once in a while, it doesn’t, and might read “zero”. The sensor in the FP1 is analog. I don’t know for the FP2 and …

Warning! Battery temperature too low, your device will be shut down

I totally agree with this.
