> It would be very useful if you could, please, monitor the CPU temperature, using the commands described in this earlier post. For now, it would be good enough to pull the values manually every 30 seconds or so while using the phone, and immediately after the phone exits the suspend, and put the values into a textual file or a spreadsheet. I hope this isn't too much to ask you for. ![[Image: smile.png]](https://forum.pine64.org/images/smilies/smile.png)
If you find that a nuisance, I can write a script that pulls and saves the values automatically.
I'll look into it, and write a guide to set this up. Feel free to ping me if you don't here from me soon. I plan to write a systemd task that runs post resume, and a cron task that runs every 30 seconds when the phone is on and not sleeping.

Yes

That's probably what was happening

I was using the Lenovo P2 charger with the provided red cable. It's a USB-A charger with Qualcomm's Quick Charge, which I don't expect the PinePhone to take advantage of and which is incompatible with USB-C. Charging the Pinephone with it is quite slow, it takes several hours to charge the phone. I think It's defaulting to 5V. The CPU was used as its maximum.
> I'd suggest that you keep the phone suspended to RAM when unused even while a charger is plugged into it, because suspending the phone allows it to cool down. As a side note, you can always initiate the suspend to RAM "manually"
I need the phone to be awake: I'm often displaying chatty remotely using ssh X11 forwarding. I also want it to be quick to notify me of calls and texts. But I'll try to think of letting the phone sleep during the night. Or even better, run a cron task at night that suspends the phone if the screen is off and nothing is playing.

Yes

Arg. I forgot to click on "Add attachment". Here it is but I'll try to take a better picture if I have the chance.
So, yes, it is worth to notice that because it is slow to charge and discharges quite a bit when unplugged, my phone is plugged and not sleeping most of the time.
The phone is currently plugged, has been charging for more than an hour (39% charged), not sleeping, running chatty over ssh, on a couch (to which it is probably dissipating heat). Its current temperature is:
cat /sys/class/thermal/thermal_zone0/temp
36718
Which does not seem quite hot actually. Is it possible that the dock was drawing power from both the phone and the charger?
