iPhone 11 Pro Max - Battery Capacity at 97%

There is no issue. Battery Health is an approximation, and it not exact. Unless the battery health is reading 80% at a year, there is nothing wrong with it. You may check it again in a week and it may be back to 100%. Unless you are experiencing a problem with the battery charging or working, I wouldn't even look at battery health.

You cannot compare the battery health of your phone against another phone. No two people use or charge their phone's exactly the same way. A 3% drop is NOTHING to be worried about. The only time you should be worried is if your phone drops to 80% or less in the first 12 months. Two weeks before your one year warranty is up, check it. Until then, stop worrying about it.

Non issue. Batteries are consumables. They start to lose capacity the day they are manufactured. Your battery is warranted for one year, and is designed to remain above 80% through 500 full charge cycles. If you do the math that means it should be expected to lose about 1% of capacity for every 25 full charge cycles. It doesn’t stay at 100% for 499 full charge cycles then drop to 80% on the 500th cycle. If it goes below 80% in the first year (or 2 years if you bought AppleCare+) Apple will replace the battery under warranty. Out of warranty they will replace it for $69. Additionally, the gauge has greater precision than accuracy; it’s best to only check after you have charged the phone to 100% for the greatest accuracy.

All of this has been discussed in the thread you posted to, which is why I suggested reading it.

You all keep saying it's an "issue," which it most definitely is NOT. Battery health fluctuates and yes, declines with use. Batteries are consumables and every time your battery goes through a full cycle recharge, it depletes a little. iPhone batterie's will provide normal use through 500 full recycle charges before needing to be replaced. The health indication will also change depending on when the reading was taken, and will change based on how the iPhone was being used just before the reading.

A drop of a couple points IS NOTHING to be worried about and would not be an issue Apple will address or do anything about as there is NOTHING wrong with your device.

It may feel like a pain to you, but you are reading too much into this. It is not a problem and replacing the phones is not going to change things. I'm surprised that Apple is replacing the devices with a 97% battery health. As has been stated numerous times in this thread, unless the battery health gets down to 80% within a 1-year period, it isn't a problem. Battery health is an estimation, and is based on the temperature of the battery, charging cycles, and usage statistics. Continually checking this status is also a problem as well. You may find that one day it will be a percentage or two above what it was the last time you checked it.

I got my 11 pro max a month and 3 weeks ago and it’s already at 96% like what how is this possible. I feel like this is a issue because my brother has the regular 11 and his is still at 100% we both got the the phones on the same day. Like I’ll get it if it dropped maybe one percent but 4% I feel like it’s too much and not normal!!

It means you and your brother have different usage patterns. Yes, it's normal. There is absolutely no reason to be checking battery health unless your phone isn't working properly or you're nearing the end of your warranty. If you're near the end of your warranty, you should check to see if it's below 80%. If it is, Apple will replace it under warranty.

Your battery is not damaged, nor did connecting it to your macbook damage the battery. DO NOT Get all worked up over battery health. And the only time Apple will say you have ANY issue is if your battery health drops to 80% or less within the first 12 months. Otherwise, do yourself a favor and simply stop checking it. Or keep checking it and upset yourself over nothing. Your choice.

That’s because there are no issues until it reaches 80%. It is expected to drop 1% for each 25 full charge cycles, so after 142 it should be about 93%. Which it is. Are you only checking when it is at full charge?

And 98% is not a problem with the battery. There is nothing wrong with your Battery Health unless it reaches 80% before 1-year of use. Stop obsessing about battery health. Don't even look at it until it seems you are having an issue with the battery staying charged, or something like that.

Apple replaced it because both guys that helped me said this shouldn’t be happening and it’s not normal behavior. I agreed because all my phones have made it a long time before dropping unlike this one. Also I treat my phones very well . At the rate this is going I’ll be down to 80 in no time. May I ask why checking it is an issue ? Just asking.

Your battery capacity is not measured in weeks or months, it is measured in full charge cycles. One full charge cycle is discharge to zero, then charge to 100%, or any combination of charges that total 100% (for example, charging from 30% to 80% twice). It is spec’d to stay above 80% for 500 full charge cycles. That works out to about 25 full charge cycles for each 1% drop in capacity. So depending on how heavy a user you are that may be a reasonable number. You should only check it after charging to 100% and right after restarting the phone; that is when it is most accurate. If it reaches 80% while it is still in warranty (one year basic, 2 years if you purchased AppleCare+ when you got the phone) Apple will replace the battery for free. Outside of warranty the cost is $69 for an iPhone 11.

You can check the number of full charge cycles if you have a Mac and install the Coconut Battery app. Or just not worry about it until it gets close to 80%.

How you use it can affect the number of full charge cycles. For example, when the phone is plugged in it uses mains power, so the battery is not being discharged (and thus need to be recharged). It’s a good idea to charge it overnight, every night, so all of the “housekeeping” the phone does happens using mains power. And if you enable iCloud backup the phone will also be backed up every night when locked and connected to Wi-Fi.

I bought the iphone 11 pro max, 2 months ago and I have same problem of this community , my phone drop from 100 to 97 % in just 2 months, I phone a friend because we bought the same iPhone on december, and he registers battery at 100%, then I call apple support and the guy who attend my call told me is a normal behavior of iPhone's battery, however I'm concern that phone still dropping in that way.

Unless you and your friend have exactly the same apps on your phone, are receiving exactly the same calls, messages and notifications, are always in the exact same places and have changed your phones the exact same number of time, it's useless to compare the two phones.

Yes, it's normal.

There is NO issue. Battery health is not exact and fluctuates depending on when checked and what the phone was doing before being checked. A 1% drop IS NOT an issue. Period.

Hello,

There is only an issue if the battery health reaches 80% or less in a year.
