Having a weird battery issue with mix 4 (odin), not even sure how to or if even possible to log it - battery percentage seems to be shown incorrectly, it may stay 10 hours on 100%, then slowly start losing percentages which is normal, at some point it suddenly loses 10-40% (depending on usage before) within minutes to what should be its real remaining level and then keeps discharging normally.
I avoid using fast chargers, already tried calibrating (discharge to 0, back to full).
Any ideas what could be causing this? Busted voltage sensor, some miscommunication between its two batteries?

Battery life otherwise seems to be normal, can get a full day of light-moderate usage, I just don't know how much battery I might have left and have to carry a power bank because of that.
