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

Iphone 16 Pro Max, Battery health 100%, 28 cycles.

Always charging up to 90% and don’t let it drop less than 20%

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

I got a 16 pro max I only charge my phone to 80% and battery health still 100%

After doing some additional research, my opinion is that this is not normal for an iPhone 15 battery, which Apple claims will go up to 1,000 cycles before it reaches a Maximum Capacity of 80%.

"Batteries of iPhone 15 models are designed to retain 80 percent of their original capacity at 1000 complete charge cycles under ideal conditions.*"

iPhone battery and performance - Apple Support

That would translate to a 1% decline for every 50 charge cycles. We've been making the mistake of assuming that the old guidelines........a 1% decline for every 25 charge cycles.....applies to the iPhone 15 (and iPhone 16).

The wild card here is that Apple also states......(in the hard to find footnotes).....That these numbers are based on "ideal" conditions, so the easy way to explain that the battery is declining at a rate faster than the claims would be to state that the iPhone must not be operating under "ideal conditions".....whatever they are. I can't find anything that details or defines "ideal conditions".

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 %.

This is my battery Health im charging up to max 80% Thats all so u can abuse the battery just not charge to 100% li-on batteries are just not made to be charged to their maximum capacity apple uses it as marketing strategy but the battery won’t last that long just carry a high speed charger is everything I used its 35w

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.

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.

Oddly I have the 16 pro and I’m at a cycle count of 255 and still at 100% health. Some batteries clearly degrade quicker, you need to stop focusing on it and either sell it when you can or accept that you’ll have to get the battery replaced at some stage.

Your battery health is going to drop and that is inevitable. It is great that it still shows 100% after 255 charge cycles, but don't be surprised when you see a sudden multiple point drop. When using a Charge Limit, the battery health will not update until it has been given the opportunity to charge fully to 100% and on occasion will do that automatically even with the Charge Limit if it is allowed by keeping it on the charger.

The battery in your iPhone 16 is expected to last for 1000 charge cycles before it falls below 80% and will need replaced, so with 255 charge cycles it would not be unusual to see an adjustment that will drop the Battery Health closer to the 95%-96% range.

I agree that it does no good to focus on the Battery Health number and simply enjoy your phone. For a phone before the iPhone 15, you can expect to get 500 charge cycles with newer phones getting 1000, and anything better than that is simply a bonus.

I have iPhone 16 Pro, Battery health is 100%, 108 cycles.

I personally charge it up to 80% and try not to let it drop below 20%

The Maximum Capacity of your battery was close to 103% when it was new, but Apple will only display a maximum of 100% for this setting.

Soon, the Maximum Capacity will start to decline normally.

What did the technician say when you tool the phone in to the Apple Store / Genius Bar to have the battery checked and tested?

Battery life, how long an iPhone lasts on a single charge and is what I see mostly being complained about here, is a different issue from battery health. As has been said already, the iPhone 16 is far too new to have any data on how fast the battery will degrade, though I don't expect it to be significantly different from previous models of iPhone.

As to how long your battery lasts on a charge, there are some tips here:
