Maximum Capacity is at 98% in less than 2 months on iPhone 16 Pro

I have my charging limit set at 95% for my iPhone 16 pro max and let it die frequently and my battery health is still at 100% percent with 6 months of use and I heavily use my phone so it has to be a defect with yours

I’ve been using the iPhone 16 Pro for around six months now I got it from Verizon. As you can see in the picture below. I have 128 charges and I have limit my battery life too 95% via the limit system that Apple implemented

iPhone 16 pro, battery health 100% with 86 cycles in about 4 months and a half of use. Always charge to maximum 90% and try to charge before dropping 20% and almost always use a slow charger (5W) which can take about two hours to full charge yes but is much better in controlling temperature of the phone while charging and so preserves battery life significantly over time. Only use a fast charger (20W) when for example I have to go somewhere and my battery is low, then I just plug it for about half an hour on the fast charger and that’s more than enough to make my battery last when I’m outside. Some extra tips I use are, turning off unnecessary location services (both on apps and system services), using most of the time reduce white point which improves battery life by slightly dimming the screen, using notifications summary for most apps except messages or social media for example, turning off mail fetch and those battery drainers features on the default mail app as I use the Gmail app and finally turning off background app refresh for most apps except maybe those you use the most.

For my experience I have gotten new iPhones in roughly December of the release year and issues tend to be ironed out by then. My battery is still great on my 16 pro after almost 6 months. Just hit 120 charge cycles with 100% battery health. Charged up every night or every second night and no charge limit set, just auto brightness and turned off background app refresh.

So I have been using my iPhone 16 Pro Max since 1st March and now it’s 10th June.

I used my iPhone really badly and I accept that because it’s currently on 175 charge cycles however the batteries health is still 100%

I do heavy gaming on my iPhone and I use this in high temperature usually above 40°C. I charge it to 100% overnight but the optimise charging is on.

I listen to music, I multitask too.

Till now, I’m really satisfied with my iPhone though it really heat up quickly, however, the battery health is still at 100%.

I keep my iphone above 20% and don’t drain to 15 or less every time. so yes I am satisfied with my iPhone 16 Pro Max until now.

100%, 107 cycles.

Charging capped at 80%(it sometimes charges to 100% on its own) and I don't allow it usually to drop under 40%(only once had 22%).

I always trickle charge it(1.5A or 1A charger with good ripple) - very few exceptions here(<10 times charged faster).

Normal usage: mostly streaming music all day(while working), a little bit of hotspot usage, making photos and using the browser - NO gaming or instant gratification social media apps like TikTok.

Yes, down 4% in 4 months. Perfectly normal (as it says in your screenshot).

And, it may go another 2 months at 100%, then suddenly drop to 96-97% the next month. That is not unusual.

There are multiple ways to charge a lithium battery. The are many factors that affect overall capacity of the battery.

Every night I charge my battery to 100% by enabling Optimized Charging to 80% and then letting it charge to 100% by the time I get up at about 5:30 AM. It charges to 80% by about 3:30 and then slow charges the last 20% so it’s at 100% and ready for a full day if need be.

I’ve done this for the last 6 years or so. My iPhones are usually between 97% and 100% at end of first year. My iPhone 16 Pro Max is at 100% and I got it the first day of availability in September.

Remember that Apple always rounds down any "tenths" in the Maximum Capacity display to the nearest whole number.

For example.....98.9% will display as 98%, even though the battery is only one tenth below 99%.

So the battery display may have dropped from 100% to 98.9%, a drop of only 1.1%, but this will look as if the battery dropped 2% from 100% to 98%. Significant difference there.

It's just way too early at this point to try to estimate how long your battery might go.

At a cycle count of 200, chances are the battery will be at about 92%. At 375 cycles, the battery will in the 85% range.

If the battery is really defective, and drops below 80% in the first year, Apple will replace the battery at no charge.

This is not an answer to your original question.  I have noticed your use of your phone has an unusual Activity being used in one particular App.  The ‘’Home and Locked screen” App;  Has an extraordinary amount of use.

I use my IPhone 16 PMax for a few hour a day.  And my Locked Screen use is a few minutes.  Maybe an average of 4-5% per day.  Yours is over 2 hours use when the phone is locked.   I am not an expert.  But, you might have some settings that might be helpful to reduce this particular issue,  And possibly the amount of “Dynamic Island" features, Live Activities that are active when your phone is locked.

Batteries, like people are individuals. No two people age exactly the same and batteries don’t age the same either. The exact usage, chemical makeup, storage conditions, exposure to heat and cold and about a dozen other factors mean that every battery ages differently. Battery aging is not a linear (straight line) and degrades at different rates as the chemicals in the battery age and other factors mentioned above. Apple expects your battery health to be at 80% after 24 months. If your battery health misses that expectation, contact Apple Support.

Please review the Apple Support articles on battery optimization. It contains the best current practices for battery charging.

Several users.....including me.....have posted to this thread to say the your battery performance is normal. I made the mistake of assuming that the iPhone 15 and 16 batteries were similar to previous models, but have done some additional research, which I just posted a few minutes ago.

Your battery performance is not normal. My opinion.

The good news is that you should get a free replacement battery since it is nowhere close to meeting the claims by Apple. The bad news is that Apple will likely tell you that the Maximum Capacity has to be down to 80% before they will replace it.

The issue is lithium ion batteries do not decline in a pure linear fashion. It’s entirely possible it’ll decline just 1% in the next 100 cycles.

Apple will run diagnostics and if nothing is showing as defective, I doubt they’ll do anything. The 4% decline is unusual, but I don’t believe is indicative of a defect. But in any event, diagnostics is the next step.

Based on the above report, it can be inferred that an additional 280 charge cycles will be required to lose another 16% of the battery’s maximum charge capacity. This means the iPhone 16 Pro battery will reach 80% capacity after 350 charge cycles (around May 2026).
