Battery Condition
I recently bought my iPhone about 2 weeks ago, the battery was 100% and now it's 97%. I don't know why, I usually only use it for calls, chat with my friends and to see movies or series. I only charge it once a day but I don't know why the condition is deteriorating very quickly, I connect it when it is at 20% and disconnect it when it is at 80%, I take great care of it. I would like to know if this is normal or something is happening with my battery. It is with IOS 14. I attach a picture of the condition of the battery.
iPhone XR, iOS 14
