Screen dying already?

[dsimic]

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.

I'll also have a take on a simple script that would pull and record the values automatically.

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.

As far as I can see, that USB charger should be able to provide 2.1 A at 5 V, which should be good enough to charge the PinePhone.  You can check the charging current limit negotiated between the phone and the charger, together with other interesting parameters, using the following command:

Code:

cat /sys/class/power_supply/axp20x-usb/uevent

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.

This looks exactly as you've described it: a two-stage screen delamination, so to speak.

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?

Quite frankly, that's unexpectedly low for the load you've described.  Under similar circumstances and with the CPU thermal throttling left at its defaults, I've never been able to achieve CPU temperatures below 55-60 oC or so.  Have you modified the CPU thermal throttling parameters?
