iPhone 15 Pro Max Battery health dropping faster

After just 109 battery cycles of Iphone 15 pro max, my phone’s battery health dropped to 96%. Is it normal or there is an issue with my mobile ?

ITS REALLY CONCERNING.

I’m having the same issue with iPhone 15. 30 cycles battery health-98. I think this issue is because of recycled cobalt used in 15 series batteries? Or Apple intentionally doing it to gain profit from battery replacement. 🥲

I went to apple Brisbane and I am also experiencing a decline in battery health to 99%. My phone is less 2 months and I already experience battery decline to 99%😫😩

It is very unclear for me why is there a quick decline of battery on my 15PM compared to my 14PM. I am really very unhappy How they advised me at apple store. I hope we get a replacement unit if the first batch of phone issued was faulty. It is not usual for a brand new phone to just drop at 99% in less than 2 months of regular use..

Whats this then?

i still have 100% after 81 cycles. i think it depends on the user. id recommend only charging to 80%. you can set an 80% limit in settings on all 15 models, settings>battery>battery health & charging>charging optimization and select 80% limit. i charge my phone overnight so only charge to 100 if i really need it. the 80% limit helps so much especially charging overnight.

Mine it’s similar!

iphone 15 battery says “99” and cycles 33! I bought it in December

iOS17 battery health is reporting wrong i think … Or apple uses batteries from less quality. I’m still at 100% health (sept25 - now / 17 charge cycles) but in analystic files it has already dropped from 104% to 101%. My iphone 14 pro was after 6 months still 101%. So my iPhone 15 pro drops faster and i take care of my battery like a freak.

Im so happy from my battery. Buying my 15pro max Octomber, after more than 4 months and 165 cycles the battery life is 99%, just 1% drop. Absolutely amazing battery life at the new max model ! Btw I aways charge the phone up to 100% and let it go to 10-15%. This 20 to 80% myth is not true.

"iPhone 15 Pro Max Battery health dropping faster: [...] I checked apple community seem like this is the common issue on iPhone 15 Pro Max, but apple non stop saying this is normal…….. did anyone having same issue with me ? I think that apple still not taking any action on this issue, just will saying my software tested working fine with your battery…………"

Troubleshooting iPhone Battery Health Dropping After iOS17 Update:

A. Downgrading the iOS:

Unfortunately, the iOS cannot be downgraded to a lower version. So, you only option, when it comes to restoring from an iPhone backup, is to restore from on that is of the same iOS version.

B. Report this to Apple...

Draining iPhone batteries and overheating are a well-known issues of the iOS17 update. Question is: "Just how many people have actually reported this to Apple?"

So, do your Part: Provide Apple with feedback on this, letting them know about this issue.  Apple may not get back to you directly, but the more feedback they receive on this, the more they will know what is occurring, and what bug fixes to include in updates to come. Apple will know nothing of this, if you don't report it to them.

1. Go Here: Feedback - iPhone - Apple
2. Select: "Bug Report" for the "Feedback Type"
3. Comment: that this all began after installing an update. Include the URL of this thread
4. Proceed from there as necessary

Because it is normal for the battery to decline about 1% a month on average. Some users do better and some do worse. Personally, I do a little worse than average, but I'm a pretty heavy user.

The important thing to remember is to replace the battery when the Battery Health is down to 80%

I called them regarding this issue they said to my phone for a week or 2.. coz it is unusual for a new device to behave like this. Mine have 30 cycle and it went to 98% with heating issue after i updated to 17.3

Same issue on my iphone 15 pro max

You are welcome.

Get this Serviced:

It may be a standalone issue, but less likely is expected to be. Note that is common among one iPhone models that have iOS17 installed.

My iPhone 15 has drain battery health to 98% within 4 months, is their any provision to replace my iPhone with new one

No. Apple will replace the battery if Battery Health falls to 80% or less during the first year.

If your phone is 4 months old, you would expect the Battery Health to be at about 96% at this time. You are doing better than average with your phone. Lucky you.
