Hi, i bought an used IPHONE SE 3 weeks ago and updated to latest ios 12.1.2, so far the phone’s performance is really good, and the battery last 1 day with full use, But when its charging once it reaches 94-95 percentage it juz stuck there for hours until i restart or plug out from the charger and recharge after 5 minutes then it reaches 100%, May i know what maybe the cause of this problem?

It could be a sign of a defective battery. I would try swapping out the battery.

If you do get a new battery, I would either ask apple to see how much they charge (I think it’s pretty cheap) OR get one from ifixit. They have pretty good batteries. If you go the cheap route, you will get what you pay for believe me.
