Might be possible that there's a calculation issue regarding your battery level, but that's guessing around.Thanks for your answer! These are the only mods that I use. I'm sure I attached the correct one, because it's the only dump I made (apart the one from 95 to 92%)
EDIT: the only mods I used also on my previous phone are iOS Keyboard Sounds (but I saw that that modulus only replaced .ogg files, there isn't any extra configuration file) and the Systemless Hosts.
EDIT2: I'm using (only on OP8) the app Battery Charge Limit to stop the charge to 80% and reset battery stats when it does so. I don't know if it could help.
In my opinion it would be helpful to make a new dump and check if the battery level is the same as shown in the system and not 65% where it should be 80% according to your information
