iPhone 12 battery life span

After upgrading to iOS 15 my iPhone 12 battery health dropped in two weeks from 100% to 97%.

To be mentioned that I use authorised charger and lead!

My phone is 10 months old.

I never left my phone on charge over night or reaching 100% charge.

Is it something wrong with the update?

Am I entitled for battery replacement?

Thank you.

I am experiencing the same issues on an IPhone 12. I purchased the phone about months ago phone about 2 months ago. Since upgrading to IOS 15 within 2 hours my battery drops to 40%, just by using navigation and basic searches on Safari and within another 2 hours the phone is prompting for low battery mode. I am identifying the phone is not changing timely. When attempting to charge it is taking several hours. Example battery was down to 15% - I plugged it in to charge and after 5 hours it had only charged to 79%.


I am reading other users comments on the same things with iPhone 12. How is Apple going to address? Is there away to go back to the previous release?
