Battery Health - IPhone 16 pro

Well, it’s been already one and half years since I purchased this iPhone in India from Iplanet and I am having doubts regarding the battery health when compare to other users with mine, so I would like the community people to tell me that whether this is normal or health drop depends upon upon the usage of the user.

After updating to iOS 27, I have two percentage drop from 90 TO 88 percentage.

Battery Replacement

I’m considering replacing battery on my iPhone 15 Pro (currently 89%) because it lasts 5-5,5 hours, so I’m asking for advice, anyone who has replaced his battery with original battery from Apple, how is your battery life? How much did it improve? Should I replace it?

Need advice on the battery life of a recently bought used iPhone 15 pro

Hey y’all. So my Pixel 7 was basically falling apart and I opted to get a used iPhone 15 pro 4 days ago as I wasn’t willing to splurge on a current gen iPhone at this moment. I found one in natural titanium which is in mint condition, no scuffs or scratches on the body/screen and everything functioning perfectly with no repair history. (This is the only color I really like, plus the black and blue models had slight scuffs revealing the titanium color underneath. It was also the only used natural titanium model with no repair history available out of the 7 or 8 trustworthy suppliers I tried in my country)

Now the catch was the cycle count (863) and battery health (86%) on this particular device, however it was a good price and managed to knock the supplier down further after pointing this out, given I knew a battery replacement is likely around the corner and they were happy to do so. The first 2 days after restoring data and updating to iOS 27 were brutal, especially while indexing. The indexing is done now and it seems a bit better but I’ve also read that things may still be running in the back for the first week or two. Overall happy with the purchase but my main question is, should I use it as is (getting maybe 5hrs SOT on WiFi) and run this battery down before proceeding to replace or just pull the trigger on replacement now?

Every 5 cycle count 1% battery health drops.

I purchased this phone from a dealer less than a month ago and this was a demo phone(warranty was over and demo phones don't increase cycle counts if they are in official apple stores) so i saw a fair price and took it as it was having 100% health and very less cycle count (34) but i've noticed the pattern that after every 5 cycle count 1% drops now at 94%, and that concerned me so i took the phone back to the dealer he says he doesn't know what's going on and he can't take it back as it dropped 6%, i also checked with 3utools but it showed everything was good no boost nothing. so now i'm stuck with this... i just want to know what can be done.

My 15 after regular use ☠️

I’m usually under 30% with only mostly Bluetooth usage, little screen time by 12pm.

Is this normal?

Ive had this iphone 17 pro max for less than a year, im trying to get a new unit because my phone sometimes overheats even just using instagram while scrolling in bed.

Ive got no idea if this seems like a unit or battery issue, do you guys have any idea?

My friends got their model earlier than me, at around 200 cycles and still 100% battery health…

60% gone in 4h20. Is this normal?

So I just bought this used 17pro with 100% battery life and 216 cycles. Background app refresh off. No AOD.Comparing it to my old 13pro with 77% life , it is better but i still get the “range anxiety”. Is this normal until the icloud setup does its thing for the first 2-3 days? As per the second photo it’s the second dat i’m using it.
