iPhone 15 Pro Max iPhone 15 owners, what is your cycle count and battery health?

I hope it will!
But if rumors are true the 17 PM will get 5000mAh
Its funny that my battery was depleting so fast UNTIL i hit 80%. Currently at 391 cycles.
I highly doubt mine will drop to 79% by September 19th. Plus I just cracked the screen while using a screen protector, and I will not be getting that fixed until the week before the announcement. I’m still trying to see how many charging cycles I can get out of this phone.
iPhone 15
First use September 2023.
on 24th July 2024 the stats were:
Max capacity 99%.
Cycle count 288.
I use a MagSafe charger, but I don't do overnight charges.
Charging is optimised.
Max capacity 92%
Cycle count 650.
Looks like a 3% loss of battery health over 5 months or 130 more cycles.

Well here’s my update:
After seeing some of you’ll having similar percentages with far, far less cycle counts, I don’t think my battery is as bad as I thought.
How in the world does your iPhone reach 81% health after 856 cycles while mine is at 90% with 670 cycles
But like how? Do you use your iPhone day and night and are you using it as personal hotspot for the entire town?
Another member has 846 charging cycles. I’m at 746 cycles with 81%. I run it down to 0% and charge it back to 100%. I’m charging it twice a day now. I just have a bad battery.
A bad battery from the start? I didn't even know you could have such differences in battery performance
It’s impossible to tell. Battery tech is chemical (reaction) based. So, its behavior can fluctuate significantly depending on many factors. Just look at coconutBattery logs, how the measured charge state can show notably worse or better from moment-to-moment, hour-to-hour, day-to-day, and month-to-month.
Have you, @BelgianChoklit, (re)calibrated your iPhone’s battery (recently)?
As to why… I’ve re-referenced this thread enough:
An iPhone battery can last much more than 1000 cycles!!!
Ok so now I calibrated the battery once and the coconutBattery health aligned to battery health of the settings app. It displays 90% now, which should be the real SoH. And not the 100% from before. This shows that an uncalibrated battery management system can show a false health value for the...

Apple should have kept their knowledge base article on the subject available. All of the guides I dig up add superfluous and sometimes outright strange steps to the process. Therefore, I’ll try to quickly summarize:
How To CALIBRATE iPhone Battery in 2025 - GeeksModo
In this article, I’ll show you how to calibrate the battery of your iphone. But first of all, let me tell you what it does and why you should do it. First of all, it’s worth noting that calibrating the battery of your iphone will not improve your iPhone battery life.. Lithium batteries will...

By the way, the recalibration process causes no extraneous degradation, namely because it’s brief. That is, you’d need to leave the battery cells fully discharged or fully charged for days or even weeks for that state to cause any noticeable, permanent damage.
How to calibrate iPhone battery to fix inaccurate percentage | NoypiGeeks
Here's a step-by-step guide on how you can calibrate your iPhone battery, why you should do it, and other things you should know.

Battery Calibration
All newly-installed smart batteries should be calibrated as soon as possible. This helps your phone or laptop get an accurate reading on the battery’s state of charge.

P.S. I think it’s important to cite sources but, ugh, websites are unforgivably aggressive with ads nowadays that I feel a little bad even referencing them. I want Safari to have a preference option to enable Reader mode by default.
iPhone 15 Pro Max
83.59%
610 cycles
Manufacture Date July 2023
First Use September 2023
Mine had already reached 84% March 2025, but pretty much stuck there for half a year, dose not look like it will drop below 80% in time for the AC+ 2 year replacement. I turn off all the battery health management and let it charge to 100% whenever possible. I feel the battery health dropped much more during the 1st year of usage, if you can remember the first few months after release iOS was not even tuned correctly that the 15 Pros all had heat issues.

I wouldn’t say it was bad from the start. It started degrading more after the year mark. That’s when I started to notice that I had to charge it more frequently. I haven’t changed my usage habits from my 14PM almost 2 years ago. Everyone is going to have different battery performances based on their usage, and I want to assume the battery in their phone.
I'm still stuck at 81%. I think Apple is trying to avoid replacing my battery.
Wow your battery is really holding on. There’s no way my battery would hit 79% at 750 charging cycles by September 19th. I gave up. At this point I’m just trying to see how many cycle I can reach by trade in.
Also, doesn’t the battery kind of plateau as it gets older? I’ve seen phones with several thousand charge cycles that were still in the near 80% battery health range.
Yes there are many factors, but lately it is common to see well into 800-ish cycles and still the health never drops below 80% on some devices. I have an iPhone8+ at 876 cycles with 82%, and a iPad Pro 12.9" M1 at 865 cycles with 84%. It seems the battery tech has reached this point. But I also traded in an iPad Pro 10.5", it was not even 600 cycles and already dropped to 50-60% I recall.

Original Apple 20W wired charging (20-80%). Kinda disappointed with the decrease in battery life I’ve noticed during the last updates. Now I’m refusing the new update, sticking to 18.5.
