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

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

My 16 Pro's battery is only over provisioned by about 1.6%. A surprisingly small ammount. Usually manufacturers place a 5% over provision in the batteries so that even when you buy a phone that's been sitting on a shelf for six months. It'll still have the full rated capacity This reply is not looking for advice or feedback . I am simply adding information.

16ProMax

92 charge cycles and a 100% battery capacity, this device is ready to go.

Charge it all the way 80+ w/o Disconnecting charger. Keep minimum cycles possible. When you charge Max it Out.

Im using 30W Charger.

Disable Clean charging

Enable Optimized Battery Charging.

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.

Doesn't sound like it's dropping to drastically to be considered defective but that's still going down pretty quick. Do you turn off your background app refresh for apps you don't need updated unless you check them yourself? I'm at 122 cycles on my 16 pro max and still at 100% health I use a 45watt anker block and oem c to c cable. Maybe have Apple run a diag on it.

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

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.

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).

It’s optimal to keep lithium batteries at 20%-80% and never letting it die. What I do is charge my phone to the mid 70’s at night, then put it on airplane mode and I don’t charge it over night, been doing this for well over a month since I’ve gotten my 16 and battery is still 100%

My 16 is still 100% with the cycle of 144 and using it since early October, maybe the risk of health dropping down is from the over usage of screen time and gaming, i personally don’t play games or watch many movies, and charge from 10-20% to 80-86% regularly with a normal USB-C cable Apple has provided in the box.

And i’m using a base model, which means 60hz display probably eats less battery and it’s something you can adjust in the Pro model to save bit of extra %.

I have a iPhone 16 had it since October I’m at 237 cycles with 98 battery percent health

At 237 Cycles, your Battery Health should be about 95-96%.

is that bad

Your battery is doing much better than normal. You should send flowers to Apple.

Lucky you. Since Battery Health normally declines at about 1% for every 50 Charge Cycles, your battery should be at about 96-97% at this time.

What this really tells me is that your battery was actually closer to 103-104% when new, although Apple will still display that as 100%.

At some point soon, you will see the Battery Health start to decline normally.

Still.....you are one of the lucky ones. Unfortunately, averages dictate that not all users will be lucky. Most will be close to average. The users who are not lucky are posting here complaining about their battery.

always on low power mode, charging capped at 80% and I use my phone pretty light, ~3 hours a day max.
