iPhone 15 Pro Max Battery Health Dropped To 99% In Less Than A Month

Hey bud, how’s your battery health right now? Still in the process of accepting the state of my battery health. Minimum usage and it still dropped to 99% in 27 days from purchase date.

Most likely it dropped to 99.9% because battery health doesn’t include the fraction. But as a normal battery loses about 1% a month you are right on target.

Is this something new because I had my iPhone 14 Pro for 1 year and the battery health was still at 100% when I got rid of it. I haven't changed my charging habits only us about 40-50 of my battery during the day turn it off at night and charge to 100% 1st thing in the morning. Now with the 15pro max Ive experienced what you just answered after 25 charging cycles

Why are you shocked? It's been mentioned several times here, it's normal.

Apple states that a loss of 1-2% of battery health per month of use is expected.

If it falls below 80% within one year, Apple will replace your battery for free under warranty.

I also bought the iPhone 15 Pro Max in November 2023 and was surprised to see the battery health at 99% when I checked it the other day this January 2024. I'm not a heavy app user, mostly sticking to Messenger, email, and WhatsApp. I've been an iPhone user since the XR and the 13, and the battery usually drops to 99-98% after a year. This is a bit concerning. :( I hope Apple will make improvements for the better in the future.

Did you read through the posts in this thread? I'm guessing, you haven't. There is only ONE way battery health goes and that is DOWN. Battery health declines with every full cycle charge. If you've only lost 1% in battery health since getting the phone in November, you're doing very well. On average, it is normal to lose about 1% in battery health per month of owning your iPhone. The health will continue to decline and you cannot stop it. It's what batteries do. ALL BATTERIES. When your battery health declines to 80% one day, which it definitely will do it will then be time to pay Apple to replace the battery. Until then worrying over something which is normal and can't be stopped is a waste. There is nothing for Apple to look into here. Nothing at all.

"I got mine at launch and was on my second replacement when the battery had gone down to 99%. I contacted Apple Support about this, and all they said was, 'You must be using the iPhone too much.' I said, 'But it's a phone meant to be used daily.' They had no idea. Now, on my third replacement, I guarantee it'll be at 99% by May at the latest. An absolute joke in my opinion."

Did you read any of the posts in this thread, where it has been explained multiple times why Battery Health declines, which is normal, expected and can't be stopped? You CANNOT stop Battery Health Decline at all.

It's not bad, it's normal.

Batteries age, it's how they work.

Apple considers it normal for you to lose 1-2% of Battery Health per month of use.

If it falls below 80% within one year, Apple will replace your battery for free under warranty.

is there any ways to reduce this ? because i already do all the ways for mantains battery health conditions but the result is not helpful 🥹

I have no way to know if the ways you do to maintain battery health are correct or are the usual internet bunkum.

But here is the absolute best way to get maximum use on a charge, as well as slow the decline of battery capacity long term is to enable Optimized Battery Charging (Settings/Battery/Battery Health) and charge the device overnight, every night. The battery will fast charge to 80%, then pause. During the nighttime pause the phone will use mains power instead of battery power, allowing the battery to “rest”, and thus reducing the need to charge the battery quite as often. The phone will resume charging to reach 100% when you are ready to use your phone; it will “learn” your usage pattern. If you enable iCloud Backup (Settings/[your name]/iCloud - iCloud Backup) the phone will back up overnight also, assuring that you can never lose more than the current day’s updates.

I’m facing like this battery problem. I bought new

https://discussions.apple.com/content/attachment/001fb8cc-8655-4ddc-8b2e-681cc136c457

iphone 15 pro at last 3 months ago and then now my phone’s battery is 99%. I’m not a heavy user. I’m normally using this phone daily. Is it normal or not reduce to 99% within 3 months?

No. In three months it would be more usual to lose up to 3% so your phone is doing better than normal.

Read this thread, where it has been explained multiple times that Battery Health decline is normal and cannot be stopped.

No, Apple doesn't need to do anything because there is nothing wrong.

Batteries degrade over time with usage due to chemical aging, that's just how they work.

You can expect about a 1% drop per month with average use on an iPhone. This is an approximation, that is why it may be plus or minus a few percent on a month to month basis.

Apple recommends replacing it when it reaches 80%.

Have the same issue, this is the first time I switched to an iphone i was very careful with the charging patterns but don't know what happened battery health dropped 2% within just 19 days tried contacting apple support they did some diagnostic **** and they said it's normal, really a bad experience with the iphone 15 plus

Why share a knowledge which so common and can be seen anywhere regarding basic battery

That’s easy. Because people that post at the end of a thread never bother to read what has been already posted.

As stated numerous times, a drop of battery health of 1-2% per month of use is considered normal and expected.

You have optimistic expectations if you think anyone actually READS the messages in the thread they post to before posting.

That is not factual information at all. I’ve owned every iPhone that’s dropped and tracked battery health since that feature launched and that is not how this works.

Sorry, you are wrong. Bob Timmons is correct. What is confusing is that some iPhones have better battery life than the design target. That doesn’t mean that all iPhones do. A battery is a chemical device, and chemistry is generally pretty variable and uncertain, as well as being analog, not digital. Apple specs the battery capacity to remain above 80% for 500 full charge cycles, but that is a minimum requirement; there is no published maximum expected capacity. So sometimes batteries will perform much better than that minimum specification, and sometimes the change in maximum capacity won't be linear. There is no way to predict in advance what the real-life performance of any specific battery will be.

All iPhones have a specification for the battery. As an example, for the iPhone 14 Pro that is 3200 milliampere-hours (MaH). So the battery monitor is calibrated for 100% at that value. But there are variations in manufacturing, so some batteries will have less capacity, and some will have more. Suppose your battery had, say, 3520 MaH capacity (10% over standard). That would still show as 100% (even though it was actually 110%), but as it aged the health would stay at 100% until it fell below 3200 MaH. This would appear to you as if the battery had fabulous life, until suddenly it didn’t.

My iPhone 15 is 1 month old and my battery health comes to 99 I am also shocked

You are only shocked because you didn’t read the thread you posted to, where it has been explained dozens of times that a drop of 1% a month is NORMAL. I’m shocked that people post without reading what has been already posted about their issue.

Mine is also at 98%. I only had overhearing issues the first couple of days so I don’t think that’s what’s causing it. I do think it has something to do with the recycled cobalt they use for the batteries. I love my 15 PM but man this thing is so fragile, and has had more problems than any other iPhone I’ve had ! I wish I would have waited and and kept my 14 PM.

PLEASE read some other messages in the thread you posted to. Your experience is clearly explained in multiple messages. Especially my post that is on this page a few posts above yours, dated January 18.
