Hello,
I recently bought a brand new iPhone 15. Everything was okay, I was very excited about it. But after few days of using the battery started to drain faster. I got IOS 26 so I think it caused it. For example my camera drained 8% of the battery (I used it for like 2 minutes). Battery capacity is 100% and I have only 5 cycles. I dont know how to fix it, but I hope someone will tell me how. Thanks a lot! (sorry for my English)
iPhone 15, iOS 26
Did you buy directly from Apple? If not, it sounds like some reseller installed an aftermarket battery and most of those are garbage.
See this Apple article on how to check if the battery is a replacement:
About iPhone Parts and Service History - Apple Support
Does Alza appear in the list of authorized Apple sellers?
If not, Alza bought the from another seller, not from Apple, so it will be difficult to know whether the phone was really "new".
If the phone requires service, you can take it to one of the shops listed as an authorized service provider.

Say your phone used 50% of the battery in the period of the graph.
Camera used 8% of that
So Camera used 8% of 50% which is only 4% in fact.
If you don't get that then there is no point in looking at the battery data.,
It is normal for the camera to use up a lot of battery power in a short period of time.

BTW brand new iphone 15 from where? They were phased out a year ago.
The iPhone 15 was still current until the 17 was released in September. Many retailers and carriers still have them in stock.
The 15 Pro and Pro Max were discontinued in 2024.
I bought it from Alza, which is Czech verified eshop.

I understand it now. Thanks.
I dont see the parts and service history section and I read that if it doesnt appear my iphone was not repaired.
