I have bought my iphone15 on Feb and today(Aug) 6months old, I checked the battery health and it is reduced to 99% not an harsh use, I have cycle count of 144, Can you please help me here whether it is normal?
for 6 months 1% reduce is totally normal bro. continue using it and follow the charging practice. you may see sudden drop of few percentage in upcoming months. it will auto adjust and show you the updated battery health in upcoming months.
