I’m also seeing weird charging problems on my Pocket Reform.
From the factory the battery showed 29% and barely moved anywhere when charging, max I got was 31%. Then following another thread here that mentioned a callibration issue, I just ran it empty, and now it indeed charges higher, but still doesn’t pass ~80% on full charge.
Using an Anker 735 GaN charger (65W).
Any suggestions? Should I drain it again?
