Hi ,
Before I upgraded my ios 15.3.1 my iphone 12pro battery health was 95%. When I updated mandatory ios upgrade to ios 5.3.1 my battery health showed drop by 6 % and it was showing 89%. Apart from that discharge also happened quite rapidly. Please guide on this
iPhone 12 Pro, iOS 15
Battery Health is an inexact figure that varies with usage. The Apple battery usually lasts for about 2 years of normal use. When the Battery Health drops to 80%, it will be time to make an appointment at an Apple Store for a battery replacement. This link may help...

Thank you for response. But that did not showed up as soon as I updated. It was showing after few days of upgrading ios. Also, I bought the phone in Dec 2020 and avoid charging frequently unless required. Is it then the usual behaviour for battery?
All batteries deplete with time and usage - I'm sure you have other battery driven devices that do not cause such concern. Yours is not unusual for a 1.5. year old battery. There is nothing anyone can do to reenergize a battery. Enjoy your phone and have Apple replace the battery when battery health drops to 80%.
A battery with a health reading of 89% after a little over a year isn’t bad, it’s actually on track to last for around two years. Lithium-Ion batteries chemically age, this is normal for LiIon batteries and there is nothing you can do to stop it. I don’t see anything out of the ordinary in your case.
More likely the iOS recalculated it.
The Health is an estimate of the maximum charge compared with a new battery. It cannot drop that quickly but the estimate can be recalculated.
Thank you to share this. But I have all these battery saving feature enabled. And rate at which battery health has dropped not even within 1.5 yrs of purchase. Its quite worrying.
Battery Health decreased by 6 i.e 95 to 89% after upgrading ios to 15.3.1
