Yeah. Mine mi 10 (umi) have same behaviour. Dirty flashed from previous release.
Sometimes battery drains so much that even if phone connected to low power charger it looses battery level. Discharging when charging
This battery drain started from previous release for me. And it happens in random manner. Most of the time it works fine. and reboot seems to fix that for some time. Tried clear cache from Security app, format Cache part and clear Delvik in TWRP and delete package_cache folder and bg-dexopt-job. No result.
Not sure, but in Setting -> Battery noticed "Other" with elevated battery usage. Or maybe its normal, idk. 29.96% and 4.46 mAh/
Today noticed this. I have AccuBattery installed for monitoring battery. I left phone charging for all night, my charger can provide about 0.5-0.8 Ah (it's a "low-power" wireless charger). So when I woke up and checked phone it shows 93% of battery level and phone was pretty warm (it should not be this warm). So I checked history in AccuBattery and it shows that phone charges normally from 1 to 100% and this took 6h 4m but then it started to discharge for 1h 36m. See screenshot
Hope this wil be fixed in future releases. It's really annoying
