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

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.

it's maybe because you charge your phone to 100% every time. i turned on optimized charging to 85% or 95%, avoiding charging to full battery to prevent battery capacity affection!!! i get that you're treating your new phone the same as your older phone, but if the battery is such an issue, you should request a replacement phone because technological devices could have their own defects. nothing's perfect

I see what your problem is. I’m not an Apple technician or whatever or a moderator but I do know that you shouldn’t have low power mode on all the time. If you have it on consistently, it drains your battery. It also shuts down core processes that are important in the background Turn off Low Power Mode maybe that will help.

Good to know thank you. 🙂 Ill make sure to keep the battery above 25% because i dont want it to go anywhere near below that threshold. Also, I dont like using low power as much it kinda slow things down. I tend to use dark mode at night and then light mode in the day i keep on auto actually.

Sorry I’m late to this party.

If you chase after battery health, you’ll just end up on a wild goose chase to no where.

I’ve had iPhone since the 3GS, not every iteration until the 14 pro, I never really had issues. I know that the battery health indicator wasn’t there back then. Back to the 14 pro, the health degraded a lot quicker than the 13 pro I had. Average user, surfing and listening to music, etc. I gave the 13 pro to my son who video streams constantly, and my 14 pro battery health went way below his very quickly. Went to Apple and did all the usual, nothing worked. Only way to get the claimed battery usage time (as this was reducing) was to turn the phone off and not use it at all. Got fed up in the end and sold it, it’s pointless watching health go down a few times a month when there is nothing you can do about it.

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.

I have used mag safe cases, wallets and wireless chargers since the 13 pro.

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.

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%

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:

If the battery in your iPhone drains too quickly - Apple Support

Regards.

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".

Lithium ion doesn’t age in a linear fashion, it may hold at 90% for 6 months. This is well documented use issue with lithium ion batteries. Below are 4 different charge voltages and look how the batteries aged. Only 1 out of three aged linearly and this was under laboratory conditions so in real world would be hard to duplicate.

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.
