FP2 overheating

When phone is used continually for 10 min or more it reaches 41°C or more which according to the apk “coolify” is overheating. FP2 definitely doesn’t like games (like Frozen)…

Is this normal?

I don’t think 41°C is “overheating”. I also have a very warm FP2 (at the back, where the SIM cards are sitting) when I watch YouTube videos for a long time. I have not measured the temperature of the warm FP2.

But also other electronics (PC, laptop, TV) will become warm when you use them. So I think the 41°C at the FP2 are “normal” and not a reason to get upset.

I’m not particularly upset just wondering…
This is what I get… And phone slows down…

I experienced a similar temperature rise of the phone (~40°C, area where the processor is located).

I don’t understand why it got hot, because I was just listening to music and no other app was opened. (Flight mode was activated too)

Has anyone an idea what caused the phone to “overheat”?

FP2 crashed (while watching Youtube videos and surfing parallel, which made the FP2 very warm) and rebooted before a few minutes, after reboot it was optimizing apps and was slow and stuttering. After a second (manual) reboot it was still a bit slow and stuttering, but after a few moments it ran flawlessly again. The FP2 was already a bit cooler than at the crash. I didn’t know the cause of this behaviour, but I find “overheating” a plausible explanation.

I measured the temperature with CPU-Z and got 73°C as maximum when directly switching from Youtube to CPU-Z.

Would be interesting to know if the GPU (Youtube videos/games) or the CPU (decoding music) is heating up and how the device is handling each case. I think there are a lot of benchmarks out there to test this, if one wants to know (AnTuTu, Geekbench, 0xBenchmark)

I guess overheating (and slowing down if needed) is okay, crashing is not.

As the gpu and cpu share the same chip, the temperature is the same :slight_smile:
Also ,a 70c temperature is really high and can affect phone durability, i would suggest you to hard reset it

If I have to hard Reset every time phone overheats I will have to do it every other day… :scream:

Actually one of the things FP2 doesn’t like at all is games… It always overheats and there’s a drastic battery drain. In a way it’s good : it can prevent going numb from playing :grin:.

On the other hand it’s annoying… I don’t remember having this problem to the same extent with my old Samsung galaxy s3.

I don’t think that the FP2 can overheat as long as the software is running normally since it seems the CPU will automatically be throttled when it gets too hot. At least I assume this from the following content in the logs:
