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

Sameer ~ I am shocked that you are shocked! ...A decline of about 1% / month is exactly what is expected and normal.

But post back if it stays at 99% during the coming months — because that may indicate a problem with either the battery itself or the algorithm which estimates the battery's health.

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 had purchased iPhone 15 Pro Max in Pre orders September & it is my secondary device & i usually charges after 3 days because i just use for calling purposes only so it last 3 days almost & After 30 Cycles i have lost 2% battery health it’s so weird my colleagues have bought in November & they are using it constantly & have completed above 50 cycles & still on 100% health. I think Apple is using cheap batteries i have a plan to switch to Samsung

do not let any of these workers convince you that this is normal. You are not supposed to go down 98% in 2 months of having an iPhone. Every iPhone has had their battery life go down 1% after a year. This is obviously a defect and they won’t admit it.

Wow, I am at least glad I’m not the only one.

When I got my 13 Pro Max I followed some simple rules:

1. Charge it wirelessly (slower so that it doesn’t heat up - heat is degrading battery faster)
2. Never use it while charging because again - heat. I rather disconnect it from a charger if I’m doing something like gaming that can cause it to heat up.
3. Also not charging it overnight but it stops charging at 80% and continues sometime before the alarm in the morning which is great. So I was occasionally leaving it overnight on a charger.

After 1 year and 7 moths my battery health was on 99%. Literally everyone was asking how and for advice on how to preserve their battery life. And I always had 1 full day of battery life sometimes 2 full days. Other than being on my phone all the timeI was using it for developing apps. It was great.

Now I got 15 Pro max and after approximately 1.5 months battery health is at 98%. It’s ridiculous. I was doing the same things with charging. But it always gets hot. Also when I’m playing a game it gets ridiculously hot. The same game on friend’s iPhone Xs is not causing it to heat up at all which makes sense it’s a simple game like tower defense it’s not graphics intensive at all. It also barely lasts a day.

I have no idea what to do. I’m extremely disappointed at Apple. 15 should be way better than 13. I understand new more powerful hardware, but isn’t it supposed to make it better and not worst. iPhone is known to last long on 1% batter (compared to… other phones). Now it’s completely opposite.

I am seriously thinking about returning it and getting 13 again.

Same here. Purchased it last November 1 2023 and my phones batt capacity today is at 98% already. Last month was at 100% Can apple please replace this phone? I mean the first few months of charging the phone gets hot and it stop charging when it reach 80%. It prompt a msg that it will start to charge once phone has cooled down. Pls apple replace my phone. I think it’s defective.

It is not normal. Your assumption is in direct conflict with what Apple states. Do they offer a guarantee; no they don’t but based on what I’ve read Apple has stated that iPhone 15s will have double the number of charging cycles than it did before. The expected 500 is now a 1000 full charges. My family all have basic iPhone 15s and all are between 50-60 full cycles and still showing 100% capacity. My 15 pro max is at 99% after 26 cycles. Do the math. Obviously other posters are having the same issue. This is not an anomaly.

Tell Apple.

Feedback - iPhone - Apple

my iphone 15 pro max also drop battery health which i use very little bit and its 29 btry cycles

It's not a "bad experience," it's normal to lose approximately 1-2% of health per month of use.

If it drops below 80% within one year of purchase, Apple will replace your battery for free.

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

Yes i am facing this same issue with my IPHONE 15 recently i buy brand new iphone in 21 October and in November 17 my battery capacity is drain to 99% even i dont use my iphone very much and i dont play games and when i see this i am shocked and then i see my battery capacity on BATTERY STATS shortcut and after seeing this i am really very very shocked and feeling sad that showing my battery capacity 94% i dont know that this shortcut is showing real but many of people search on this shortcut now the main point is that APPLE doesn’t take action on it . Is it good for my brand new iPhone can I replace the battery??? i am very confused in this issue and i don’t know that our settings of iPhone battery capacity is real ?? or this shortcut battery capacity is real ?? Please help so i can take action on it 😓😤

I have iphone 15 which i purchased on 22 October and now on 5 December battery health is 98. What the **** is wrong with 15 series. Earlier battery health used to drop to 98-99 in one year. Looks like Apple wants everyone to upgrade the device every year or pay 9800₹ every year for batteries. I have decided this is my last iphone i will switch to samsung.

As always, you should purchase a product that best matches your needs. After you purchase your Samsung device, do keep an eye on the battery health. As they also employ the same laws of physics as Apple devices, the battery health will diminish with time and usage.

Update- On 11 December my phone's battery health dropped to 97 and i am a normal user. I generally use social media apps and i do not play games or any heavy apps. I again checked with apple they said it's normal and they can replace the device only if i have apple care+ plan(which costs around 15000rs in india). And i do not want my battery to replace because it's new device why would i let them open my one month old device. So conclusion is i will have to pay 9800rs for battery replacement after my device is out of warranty.
