Librem5 gets very hot when charging
I'm running PureOS with the 6.0.0-1-librem5
kernel. It's the latest according to my apt update.
When charging the phone with a 65W USB-C laptop charger. The temperature of the phone according to mobile settings will easily hit:
CPU: 49 C
GPU: 49 C
VPU: 49 C
Fuel Gauge: 51.4 C
Battery: -
That is just letting the phone charge for about 5 minutes on a table. The temperatures seem to continue to rise, although I usually get worried and turn the phone off before they get much higher.
I have the screen, modem and WiFi on.
mobile settings, terminal and top is running, but otherwise I don't see anything that isn't phosh, phoc, upowerd using a large amount of CPU. upowerd does seem to be using about 17% of the CPU.
From testing this it's pretty clear that within 5 minutes of starting to charge, the phone will get very hot. After which I have to turn it off and let it cool down until I try using it again. Unplugging the charger causes a 4/5C drop in temperature of the fuel gauge.
