Battery problem with a Pinephone keyboard and Mobian

[presire]

I am using Manajro ARM (Phosh) and I have the same problem.

uname -r

Linux manjaro-arm 6.0.2-1-MANJARO-ARM #1 SMP PREEMPT Wed Oct 19 06:43:45 UTC 2022 aarch64 GNU/Linux

Previously, it used to show 66% on a full charge,
but after updating to the latest version, it shows 33% on a full charge.

Perhaps the latest version of Mobian (Weekly) will also show 33% on a full charge.

I do not know how to correct the problem.
I wish I had a better solution....
