iPhone Battery Health 85% – Don’t Replace Your iPhone.

We heard this so many times. People saying their iPhone battery health is 85% means that their device is going to die out soon and they need to get a new one. This is nonsense. If your iPhone battery health is 80% or even 80%, you’re fine, don’t do anything.

This article will explain what iPhone battery health 85% really means, how to check your battery health and what you should do or DON’T do, and also provide you with some good tips on how to prolong your battery life so you can use it longer.

The truth about iPhone battery health 85%

According to apple your battery is considered great if the health level is 80% or more. If this is your level you should definitely NOT do anything, and keep using the iPhone as always.

Now, even if your battery health is less than that, let’s say 78%, you’re still fine, relax, don’t run to the store to buy a new iPhone.

These metrics are all just guides meant to provide data and info on the battery of the device, these are not rules set in stone.

If your phone still works without issues, do nothing. Yes, obviously iPhones with battery health of 75% will probably last less time compared to ones with health 85% or more, but the difference could be negligible. Will an added 33 minutes to your battery per charge makes that much of a difference in your daily life?

I assume not. So why spend the money on a new iPhone when you don’t need to.

So now that we got that out of the way, if you want to learn more about what the iPhone battery health really means and how to prolong your battery life – keep reading below.

How to check your iPhone battery health

Before we even dive into the details of what battery health is, it would be a good idea to know and check what your battery health is right now, so here are the steps to check your battery health on your iPhone:

iphone battery health 85%
  • Lunch the Settings app on your iPhone
  • Tap Battery
  • Tap on Battery Health

Here you can see the Battery Health section which usually just shows a number. For example my current battery health is showing 83%

the 83% is compared to when your device is new. Meaning, from the time you bought it, until now, your battery health degraded by 17% ( in my case ). I have an iPhone 11, so it’s around 3 years old now, so I think it’s pretty good actually if you ask me.

This basically just means that the time between charges is going to be a little bit shorter now, compared to 100% when it was new.

the lower the number, the shorter the time, obviously you should not let it run to 0%, I don’t really think it can, but as long as you’re in the high numbers, you should be fine.

Should I replace my battery or iPhone when battery health is below 80%

In our opinion, NO, you should not worry about it and replace it. If your phone works fine, what is there to fix?

Speaking from personal experience, I had an iPhone 6 and I used it until I upgraded to an iPhone 11 which was more than 3 years ago, and my phone works great, and the battery mostly last me the entire day, and I work with my phone.

I did the same with my iPhone 6 before that, and that lasted me around 5 years, with no issues at all.

Should you keep your phone forever? Obviously not, phones, like any other electronic device, die down with time. But you should not stress about it either, iPhone batteries can work fine for years. Reading a few threads on Reddit I can see that some people have 90%+ Battery health after 3-4 years of using their iPhones while others have 80% after only 1 year.

So what does that tell us? It basically just says that these batteries die down at much different rates based on your usage and there is no rule here. Just use it until it breaks, regardless of the health score.

Tips on prolonging your iPhone Battery Health – apple recommends vs real life experience

So let’s put it to the test, let’s see what apple officially recommends and what the real life experience has taught us.

NOTE – Please note thought that this is just our own personal experience, and in no way a guarantee about your battery health or the condition of it.

1. Update your software

So the first thing apple recommends to do to prolong your battery health is to make sure you always have the latest iOS software installed on your device.

Our real experience showed us that this is not required, I rarely update my software and honestly, I do it only when a lot of time has passed or when apple forces me to update. I do this because a lot of times if you hurry up and update right when there’s a new software, you are the first to learn about the bugs and glitches it has too.

This way, if I wait a little bit, all these bugs are already fixed, and it’s safer to update.

We didn’t find that this practice degraded our battery health – as we mentioned, current battery health is at 83% after more than 3 years of heavy use.

2. Dim your screen and use WiFi

Apple also recommends to lower your screen brightness and use WiFi whenever possible. This is actually solid advice, not just for your battery health, but in general.

Obviously, when you lower your brightness of your screen, it will use up less battery, this is just common sense, we also do that, but for different reasons. I actually keep my brightness very low because it just burns my eyes if I look at the screen at a high brightness level and it’s not pleasant. I guess I drop two stones with one throw.

Using WiFi when possible, again just makes sense. Mostly WiFi connections today are faster than cellular date and also not everyone have unlimited packages, so it makes sense to connect to a WiFi when possible. If it also helps save on battery, great! Another win for you.

3. Enable low power mode

Hands down we have never done this. Nothing against it, it just never seemed like an important thing.

Low power mode basically means that when your battery goes to 20% you will get a notification ( which you do anyway ) but when this is enabled you can turn on the Low Power mode with a tap, which will disable all non critical functions on your iPhone and in turn will save you a lot of battery.

We never used it, we feel confident that turning this on will use less battery and will eventually help keep your battery health score higher, so go nuts.

4. Avoid extreme temperatures

This is important not only to your battery health but to device itself. electronic devices are not meant to work in extreme weather conditions, they can, and probably will, but it’s not good for them.

Try and keep your devices at no less than 32F to maximum of 95F for optimal use.

Non apple official tips we heard to increase battery health

1. Letting your battery drain all the way to 0%

Some people think that letting your device drain all the way to 0% before charging it is good for your battery, however this is not the case. We didn’t find any evidence that prove that doing this will prolong your battery health. You know what it will do though? Annoy you as you would have a dead iPhone until you charge it again.

And what happens if you nearing 0% and there is no charger around? What you gonna do then genius. Don’t do it, don’t wait until your phone is at 0%. Just charge it when it gets low and be safe.

2. Your iPhone battery level should be between 30% and 80% all the time

Please, this is not true, there is no real difference between having your phone at 85% or at 80% or at 98% for that matter, and same goes for 30% or 23%.

We regularly charge our phone when the battery gets low, and it could be 20% and it could also be 4%, and we charge it until it’s full. 100%, and never had any issues with it. Don’t over think things.

3. Enable Low Power Mode

We do have this feature turned on. It basically means that the device will learn your charging habits and make sure to optimize it when you do charge so it won’t just age the battery quicker for let’s say events that you leave your phone charged for far above the 100% mark.


Your iPhone battery health is an important factor that is pretty accurate and it tells you the overall health of your battery. However, it is recommended not to stress about it, and run to replace your device when you see it drop to 83%.

As long as the iPhone works well, and has no issues and you can function with it for a reasonable amount of time without charging every 15 minutes, you are good to go.
