PPKB with phone; phone dies while charging
#1
Hoping someone can help me out.

Running Arch, on my pinephone in the keyboard case. The keyboard case works fine, even got the top row symbols working.

 I did megi's echo 1500000 > /sys/class/power_supply/axp20x-usb/input_current_limit 

Problem is after using it, I plug it into a charger and the next morning the phone is dead. I have tried 5 different chargers including dumb 2.4a. This has occurred on every distro I have tried (all of them except manjaro).

Any ideas?

Edit: I should add that when not on ac power the keyboard charges the phone just fine, so it doesn't seems to be the pogo pins

After buying 3 different chargers and cables, both PD and dumb with stated 3A 5V, testing all the ones I already had, none of which worked with the pp+kb, I remembered that the Pi 4 has weirdish (high) power requirements (and does not conform to PD), and usb-c. Plugged that special powersupply in and it charges the whole package! On Arch too!

(At least in my case) A Pi 4 specific powersupply is the answer
