I've experienced the same thing and it seems to be related to the temperature of the laptop.
While the PineBook is charging and under a heavy load, it can easily reach over 50°C. I noticed that not only the battery decreased under the load but then struggled to increase once idle. I checked the charger and it was cold, so it definitely wasn't outputting 3A. The battery started to charge after unplugging and plugging the cable back in.
Maybe it's some kind of thermal protection?
