Battery health dropped all of a sudden
i have an apple iphone se 2020 which I purchased on 22 march 2021 and its 19 may 2021 today. Not even two months. So, the thing is, till yesterday, my iphone battery health was at a 100%. In fact, till today afternoon also it was at a 100%. But now (its 8pm) the battery health became 97%. Like directly 97%. Not 99 or 98. From 100% to 97% directly. Why is this so. I never overcharge or charge my iphone over night. I plug it at 30-40% and plug it out as soon as it touches 100%. And moreover i dont use my iphone when it’s charging also. My optimised charging is on. And i charge my phone at the same time daily. And i charge only twice a day maximum. Is this a software glicth ? Should i reset the iphone? Because you know, this is like literally a brand new iphone
iPhone SE, iOS 14
