I wonder if your battery or power supply are different.  None of mine take that long to charge.

Good point. I'm not sure whether my battery or power supply have issue or not. I brought the whole set and I expected it should work out from the box.

I used the PBP for two weeks only after I received it. Originally want it runs 24/7 as my ssh vpn routing machine but gave up after it run out of power every 2 days and I have to charge it for another day. Also tried to use it as a developer machine. Mainly terminal editing using vi and cc for compilation.

I eventually gave up and brought the Raspberry Pi 400 and is now running headless 24/7.

I still looking for a laptop form factor linux machine and I do like the PBP especially the keyboard.

I won't be home to do much testing for probably over a month.  When I do get time at home, time will be precious.  Else I'll be happy to help.

Quote:I got my PBP on early 2020, still have the stock debian version running on it and with the stock power supply came with it.

I took it out last night, charged it up to 100%. Wrote a small asm program to perform endless looping. Then run the program five times in the background. (i.e. the PBP has 6 cores, I'm pushing it to 5 cores 100% load, overall 83% load on cpu)

After 3 hrs run with the A/C connected, the battery level drops to 89%.
