Hey All,

I have lately noticed my iPhone SE 2 battery health dropped to 95%. I bought it just 3 months back and health was 100% in first two months. I’m not doing anything unusual. How can I stop from being it dropped further.

And what is the best practice to charge the phone. From 0 to 100 or 20 to 80?

Thanks in advance!

I wouldn’t worry too much about the battery health figure. Just use/charge your device as needed. I’ve seen people swear to the 20-80% charge for battery longevity while others leave charging all night. Most likely by the time your battery needs replacement, you will have already upgraded to a new phone. If not, a battery swap can be done at the Apple store.

My XS dropped from 100% to 94% within 6 months however it stayed on 94% for 4 more months. Battery health isn’t linear, so I wouldn’t worry too much about it unless you notice a big decrease in operating time.

Turn it off.

No, seriously, don't worry about or even look at the battery health. If you don't keep your phones for a long time, it isn't going to matter anyway. If you are going to keep it longterm and it gets low enough to affect performance, Apple will gladly do a battery exchange for a nominal fee.

The reason there's a battery health app is because of the fallout from the secretive iOS 10 throttling debacle years ago. It's a concession to the millions of dollars of world wide fines and lawsuits over that issue. Apl never wanted battery health info available to the public or developers and they got rid of that capability completely in iOS 10 - then were persuaded to bring it back in it's vague inaccurate glory in iOS 11 after they got busted for secretive throttling.
Battery health estimates are just that - estimates. No one has ever figured out how to calculate the health of a Lithium ion battery accurately- it's only a guess..

Thanks for the response. May I know can I turn it off?

Any phone I store for 6 months unattended at 50% charge level will be completely discharged to zero after 6 months — BAD.

If a phone is no longer being used, the battery charge level should be checked every 3 months

I take cate of it doing the whole keep it between 30 and 80 percent and so far I’ve lost 1% a month.

I just checked mine and after 9 months(I got mine on August 28 of last year) I’m still at 98%. Of course I am now using that as a backup as I decided to Upgrade to the 12 Pro Max when I got my stimulus payment and much bigger than expected tax refund(and a 15% discount as I was working for an Apple Vendor at the time)

Conversely I am at less than 9 months and am at 90%. But I am willing to bet I use mine quite a bit more. It is more or less always in use and charged frequently many times a day.

I was using mine a lot before I got the 12 Pro Max. But I also have a iPad that was splitting some of the time I spent using the phone.

Yes, just after 6 months my battery health went from 100% to 92%. It’s only a small battery (1800 mAh) and A13 is way too powerful so it seems that the whole idea was a bit of a compromise from the start.

In my experience the batteries with laptops and phones seems to drop pretty rapidly till it hits around 85% and then it stabilizes there. That has been my experience with 2 batteries in my 2016 SE, a 2017 MBP and a 2019 MBA.

Battery health can only go one way over time.
In the case of my laptop, it's been bouncing around quite a bit. A steep drop after 6 months and then it's been bouncing around since between 84 and 88%.
