iPhone 15 Pro Max Battery health dropping faster

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.

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

So how are you charging your phone cause I have mine limited to 80% and I normally try and charge it before it hits 20% and I currently have 43 cycle count and 100% max capacity. Try and limit your battery usage and not charge it to 100% and try not to drain it before it drops to zero

Yes I have 100% after 140 cycles after 6 months of use i don’t charge my iPhone 15 pro max up 100% and don’t keep it under 20% i only charge it up 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

I have done 200 cycles on iPhone 15 pro max I use phone cooler so phone is on 4 to 5 degree Celsius on charging or gaming use phone cooler to protect your battery.

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.

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%

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.

my new 15 pro max with just 72 cycle count and less than 2 months of use has dropped to 99%

Nothing unusual or unexpected with that. On average, you can expect to see a drop in Battery Health of about 1% per month. Your phone is doing better tan expected, to be honest. And keep in mind that Battery Health only goes one direction and that is DOWN. When the day comes that the Battery Health on your iPhone declines to 80% or less, which it will do, it will then be time to pay Apple to replace the battery.

Batteries are consumable parts, that lose their ability to hold the same charge as new due to chemical aging of the battery.

In 6 months, with 4 hours of avg usage and without gaming, battery health has reduced to 99% with 114 cycle count. And people say it’s normal. But I say it’s not. I charge to 100% only once a week and rest all days it’s just to 80%. Never has my battery come below 30% in the last 6 months. And still health is down to 99%, in spite of following all the best practices that’s out tr.

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%😫😩

I have to keep low power mode on all the times in order to get a decent battery life

There’s a one year warranty and insurance claim can be done (if the battery is actually super depleted and if you have insurance)

How many charging cycles does it have? Do you allow the battery to reach at least 80% before unplugging? All these things factor in on battery health
