13 pro max battery showing 99% after two month

I have the iPhone 13 Pro Max as well. My battery health is at 98% after having used it for 4 months.

Battery Health & Performance 

Your battery health is fine and is undergoing normal usage. iPhone batteries, like all rechargeable batteries, are consumable components that become less effective as they age. You should change out the battery once your Battery Health reaches below 80% which will take over 2 years to reach under normal usage. Until then enjoy your iPhone.

You’re doing fine; Batteries are consumables; they lose a little capacity every time they are discharged, then recharged. On average this works out to about a 1% loss for every 25 “full charge cycles”. As one example, if you charge the phone overnight, every night (and that is what you should do; it is a best practice), it starts the day at 100%. If it drops to 20% by the end of the day before you charge it again overnight that counts as 0.8 full charge cycles (20% to 100%), or about 24 full charge cycles per month of use. For this example your battery capacity will lose about 1% per month. Of course, if the end-of-day level is higher than 20% the capacity loss will be a little less, and if it is lower than 20%, or you charge it during the day, the capacity loss will be higher.

The absolute best way to get maximum use on a charge, as well as slow the decline of battery capacity long term is to enable Optimized Battery Charging (Settings/Battery/Battery Health) and charge the device overnight, every night. The battery will fast charge to 80%, then pause. During the nighttime pause the phone will use mains power instead of battery power, allowing the battery to “rest”, and thus reducing the need to charge the battery quite as often. The phone will resume charging to reach 100% when you are ready to use your phone; it will “learn” your usage pattern. If you enable iCloud Backup (Settings/[your name]/iCloud - iCloud Backup) the phone will back up overnight also, assuring that you can never lose more than the current day’s updates.

There is no point in worrying. When it reaches 80% have Apple replace the battery. If it happens in warranty it will be free. Out of warranty (or out of AppleCare+ if you purchased it and didn’t extend it at the end of 2 years) it will cost $69. As I said, with average usage it will lose around 1% a month, so 97% after 3 months is right on target. As it is a deteriorating chemical process that slowly consumes its electrodes it won’t be linear. It only drops in whole percentage points, and the algorithm truncates rather than rounds, so a drop of 98.0% to 97.9% will display as a drop from 98% to 97%, even though it only dropped 0.1%.

Same here 99 percent in two months and I have barely charged the battery passed 90 percent ever been taking utmost care about the battery.

I know people having 10 months age still it’s 100 percent

it’s really disappointing

add to that my camera opens on its one at least 10 times a day

Once the capacity drops below 80%, or if there is a message in Battery Health that the battery is not meeting peak performance expectations, it’s time to change the battery→iPhone Battery Replacement - Official Apple Support

Batteries are chemical processes, and are not all identical. Apple’s specs say the battery should stay above 80% for 500 full charge cycles, but it doesn’t say no more than 500 full charge cycles. So through manufacturing variability some batteries will do better than the minimum specification. There isn’t anything specific you can do, other that follow best practices that I have previously posted, but here it is again:

Thank you very much, you think it's normal to drop to 99%, which I agree is inevitable, but after dropping to 99%, it dropped to 98% a week later, that seems a bit fast.

You are spending way too much time worrying about a battery that is performing above average. An average battery will be down to about 80% after 20-24 months. Replace the battery when it gets down to 80%, which will probably be closer to 36 months for you.

bruh but some of friends have the same model (13 pro max) and they’re still at 99-100 :/ they use fast charger and I never use a fast charger I am using 5w ! Can u pls tell me 5w is good for battery health or faster 20w

Unless those friends have exactly the same apps on their phone, which they are using at the exact same locations as you for the exact same amount of time, and are receiving the same number of length of phone calls with the exact same signal strength, you can't make a comparison.

I've already given you a link on battery charging but, in case you missed it, here it is again:

When to charge your iPhone or iPad - Apple Community

Review the information in that article on optimized battery charging.

You need to understand that your battery capacity will decline no matter what you do. There is nothing you can do to change that and precious little you can do to slow it down. What you're seeing is normal, expected behavior.

My advice, which I know you won't take, is to stop worrying about it. Check the battery health again before the warranty runs out. If it's below 80%, have Apple replace it. Other than that, don't even look at battery health unless you're experiencing a problem with your battery.

So what is your question. There is nothing wrong with it showing 99% after two months. Batteries are consumable, so as you use them, battery health will decline, based on the number of full charge cycles. Apple does not consider a battery problem unless the battery health gets to 80% before the end of one year. Nothing to see here.

I have purchased iphone 13 in sep and it’s battery health dropped to 99% today. So it took 7.5 months for me.

You have an exceptionally good battery, although see what it does from here. Keep in mind that a battery is a chemical device, and chemistry is generally pretty variable and uncertain, as well as being analog, not digital. Apple specs the battery capacity to remain above 80% for 500 full charge cycles, but that is a minimum requirement; there is no published maximum expected capacity. So sometimes batteries will perform much better than that minimum specification, and sometimes the change in maximum capacity won't be linear. 

All iPhones have a specification for the battery. For example, for the XS Max that is 3174 milliampere-hours (MaH). So the battery monitor is calibrated for 100% at that value. But there are variations in manufacturing, so some batteries will have less capacity, and some will have more. Suppose your battery had, say, 3474 MaH capacity (10% over standard). That would still show as 100% (even though it was actually 110%), but as it aged the health would stay at 100% until it fell below 3174 MaH. This would appear to you as if your battery had fabulous life.

Same for my 13 pro max model brought it on 31 Jan 2022

and BH now showing as 99% after 2 month but still getting awesome battery life

the reason of this sudden fall is weather here in india

It isn’t a “sudden fall”. On average a battery will lose about 1% a month. Some phones will do better, but that’s about right for your phone. Scroll up and read my long post.

Hey

Well my best friend bought his at the release of the iPhone 13 Pro Max and he is still at 100%.

My girlfriend bought her regular 13 in February and has it at 100%.

Mine 13 Pro Max made 5 days ago 3 months and yesterday he changed from 100% to 99%.

I got worried about comparing it to my friends usage and taking in consideration that he doesn’t take care about the battery following all the health tips.

Now he got 9+ months with 100% battery life that’s a record.

I went to Apple Store and they told me that all iPhones have different health. For instance my best friends phone can have 104/105% but his iPhone only shows 100 because it’s the iOS and how it is build to show.

for instance I got mine in exact 100% battery life. U can check ur health using the cocount app in ur MacOS. Those who have 100% are maybe the lucky guys who had their phones with a little more battery life.

hope that explains to u all

Sorry .. what I meant was initially it didn’t drop for first 3-4 months.. but now it’s dropping about 1% every 2weeks

but overall is @ 90% after 10mths… still mediocre health

The battery health decrease is often not linear. It may hold steady for a while then drop more rapidly. However, you're still in the normal range of what one would expect to see.

I have i phone 13 pro may battery helth showing 99% after 1 and half month (45 days) uses. It that any issue?

No, it's not an issue. The average decline in battery health is about 1% a month.
