Same problem for me Redmi Note 12 Pro MIUI 14 0.10 . Charging stops at 98%. If I unplug it and plug it back in then it goes normally up to 100%. I use the original 67w charger that came with the mobile phone.
Obviously it's not a feature. The point is how you handle it until it is fixed. Should I leave it up to 98% or plug it back in so it reaches 100%? What damage can it cause to the battery in this case?
