My iphone 14 battery health lowered down to 97% in 2 months

"I google about it and it was supposed to be only 99% in the first 6months of use."

That is incorrect, after 6 months it should be approximately 94%

Batteries degrade over time with usage due to chemical aging, that's just how they work.

You can expect about a 1% drop per month with average use on an iPhone. This is an approximation, that is why it may be plus or minus a few percent on a month to month basis.

Apple recommends replacing it when it reaches 80%. To check your battery health, go to Settings > Battery > Battery Health.

Here are some tips on maximizing battery life.

Batteries - Maximizing Performance - Apple

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. There is no way to predict in advance what the real-life performance of any specific battery will be.

All iPhones have a specification for the battery. As an example, for the iPhone 14 Pro that is 3200 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, 3520 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 3200 MaH. This would appear to you as if the battery had fabulous life, until suddenly it didn’t.

If you have a Mac you can install the free app Coconut Battery. It will show the actual percentage, even if it is over 100%.

I bought my iphone 11 on June 3 this year but after 2 months my battery health is 96%, is it normal? because I'm using mine carefully.

It's a little higher than average but not so much that you need to be worrying about it.

There are only two times you need to check your battery health. First, you should check it if there seems to be something wrong with the way your phone is working. It's one of several troubleshooting steps. The other time is when your warranty is within a month or so of expiring. You check it then to see if it has dropped below 80% and should be replaced before the warranty expires.

At no other time does it make any sense to check battery health. It gives you no useful information.

For everyone here facing issues with lowering battery health, this Is 100% normal due to chemical processes within the battery when charging and de-charging it.

Why isn’t Apple responding to these?

This is a user-to-user support forum. Apple's participation here is largely limited to making sure people follow the rules. The only posts they respond to are ones involving health and safety. If you want to discuss this with Apple, use the Support link at the bottom left of every page of these forums.

My phone is brand new, not even a year old and down to 92%

"Brand new" means less than 14 days old. As long as your battery is above 80%, it's fine. If it drops below that before the end of the warranty, Apple will replace it.

What did Apple Service say when you took the phone in to them to let them run checks and tests on the phone?

At the current rate, the phone will be at 86% in another 4 months and down to about 80% another 3-4 months after that.

If the phone is down to 80% in 12 months or less from your purchase date, you get a free battery from Apple Service.

All rechargeable batteries are consumable components that become less effective as they chemically age.

As lithium-ion batteries chemically age, the amount of charge they can hold diminishes, resulting in shorter amounts of time before a device needs to be recharged.

Apple won’t replace the battery until it reaches 80% capacity.

Your previous phone was truly amazing. Most phones aren't.

Take your phone into the Apple Store to let them run some checks and tests. You will hear the same thing from the tech guys that you hear here.

On average, your battery health lowers by 1% every month (give or take a few)

Same here battery is aging out faster

its sad apple has not yet worked on battery aging issue.

It’s sadder that even though batteries have been around for over 200 years, and the Lithium Ion batteries used in all electronics today have been around for over 40 years, people still don’t understand that all batteries wear out with use. Which explains why over half the floor space in any auto supply store is taken up with replacement car batteries.

Batteries are consumable devices, they age. No battery in the world lasts forever. Apple cannot break the laws of physics no matter how good a company they are.

I googled “flat earth” and got 866 million hits. Just because you find something on the internet doesn’t mean it’s true. In fact, probably 99% of what you find on the internet is untrue. The venerable Sturgeon’s Law says that 95% of everything is garbage; Theodore Sturgeon lived before the advent of the internet; I’m sure he would have upped his law to 99% if he had ever used the internet.

I google about "is the earth flat" and I get over 500,000 responses.

Go look up Sturgeon’s Law. But Theodore Sturgeon died before the internet; his claim that "95% of everything is garbage" must be updated to “99%, if the internet is involved."

I had a iphone7 and in that the battery aging issue started after 1 year,

today in iPhone 14 it’s showing me battery health as 97% in just 2 months.

I am not asking to break physics but to give a product which has got good battery life.

With new merging technologies I think apple should rethink about there battery aging factor and with years to come it should not happen that users have to replace their iPhone battery after a month…

Now it became 95% and its not even a month after it was 99%

Irrelevant. All that matters is how long it has been since the phone was new. If that was more than 5 months ago then 95% is what it should be.
