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

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.

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.

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

Recalibration of your battery will only happen when the phone is allowed to charge to 100%. Even when using the 80% limit, the phone will automatically charge to 100% to perform this calibration and if you manually prevent that from happening, then the battery will not calibrate and remain at it's previous Maximum Capacity.

Once you allow the phone to charge to 100% through several cycle as it will automatically do when using the 80% limit, then you will see a larger than expected drop to reflect that actual state of your battery. The number you see for Maximum Capacity is just what was determined when it gets calibrated, it does not mean you instantly see a drop in performance when it shows 98% after it has been calibrated. It could remain at 100% forever without any calibration occurring and that does not mean you are going to have the same performance as if it was brand new. Eventually you will see a message that the Maximum Capacity cannot be determined because the battery has not been calibrated.

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.

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.

Please tell are you using original cable for charging ? becouse i have also faced same issue but, unfortunately i had used fake cable thats why i have faced this issue. so i replaced my cable with original one now.

Iphone 16 Pro, Battery health 100%, 219 Cycles, Always charging up to 100% or 90, or 95, 80 and don't let it drop less than like 35%

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).

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.

I have an iPhone 16 Pro Max and have been using it since release day. I have the Always on Display enabled and I try to keep it between 95% and 15% as much as possible, but sometimes I let it charge the whole way up overnight and once I accidentally let it completely die while working. I’m actually surprised it’s held up this well so long. Its 100% capacity has lasted longer than any prior iPhone from my personal experience. There definitely seems to be some luck of the draw involved, though.

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.

You might not be aware of this, but even if you have the phone set for 80% Charge, the battery is still going to charge to 100% on occasion, and you will not be able to control this.

When I tried Charge Limits, I found that the battery still charged to 100% two to three times a month on average.

Here is the info from the Apple Support document:

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
