iPhone Battery Health at 83% - When do I replace it?

Your battery is fine, nothing to worry about. 91% is great for a now two year old battery. Don’t spend time fretting about how you use your iPhone or what its battery health is. ALL batteries wear out eventually, fact of life. iPhones are engineered to get the most performance possible for their batteries. My iPhone 13 battery health is at 90% after three years. Don't worry, be happy.

How many cycles it has?

There is no need to replace battery if you are ok with it. Batteries stabilize around 80% health mark so if all is good it won't go down much. My wife still uses Iphone 8 with 78% battery and no complaints just needs charger more often but it is fully usable and no much difference how it was when new. Of course iOS warns that battery should be replaced and that is all.

My battery is at 79% for the health. What should the percentage be when you replace your battery?

Now would be a good time to replace the battery, since Apple recommends replacement at 80%.

However, if the battery is still performing well, you could hold off for another month or two.

I've been an Apple fan since '90, doing Star Trek sound FX on a Mac SE30. But... my iPhone battery went to 83% after one year. now almost a couple years later it's still at 83% although it requires charging 2-3 times day. Apple won't let you replace battery with an Apple battery until 80%, so appears to me that Apple sticks it above that so you CAN'T get a new battery and will buy a new phone. Bought over 20 macs and like a dozen phones and iPads over the years but getting not happy about this...

If you have a 12 $400 to go up 1 generation which is still a couple years old seems like a waste. Just note the bullet and trade in your 12 in September or October when the new iPhone comes out and you’ll be set for several years after that. $400 for an old iPhone and another $100 soon after for a battery when you can pay $1000 and get a brand new phone issue free that’ll last you several years

Original batteries have a much longer life than non-original batteries, and opening and closing the mobile phone may cause other failures and reduce its efficiency.

So it is better to continue with the same battery until 78% and if you need to charge, use a power bank

You can’t replace iPhone batteries, only Apple can do that with their Apple Certified Refurbished service. All you can do is buy another iPhone in excellent condition like the iPhone 11 Pro Max for $400 from Backmarket

In addition, as Krupp pointed out, to it being possible for the end user to replace their own battery, Apple also does it in store for, in the U.S. about $80, much cheaper than buying a whole other phone.

Iphone battery 90% and cycles of charging 935 times. Is my battery original and good conditions?

If you can see the battery health in Settings>Battery>Battery Health>Maximum Capacity, it's probably and Apple battery.

At 90%, your battery should work fine. Apple recommends replacing them at 80%.

Did you read the reply from Jeff Donald above?

My battery was down to 90% after one year......then it only dropped 2% over the next 5 months when I decided to lower the brightness level a bit and stop using 5G cellular so much.

It's getting close, you will want to replace it withing the next few months.

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.

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

I am currently using a iPhone 12 which battery life is at 75% now someone I know is selling a iPhone 13 Pro Max for $400 with a 83% battery life. Is that worth doing knowing I will soon have to change the battery because for all of that I could just keep the phone I have. Change this battery and or wait to get a brand new more recent iPhone.

Only you can answer if that makes sense to you. I would point out that whether you keep your old phone or buy one with a battery with 83% capacity, you need to budget for a new battery. If the iPhone 12 still works and you don't have a lot of money, replace the battery. If the $489 the newer phone is going to cost you is within your budget, sell the iPhone 12 for whatever you can get for it and put that toward the newer phone.

Iphone 14 Pro user here, bought mine back in 2022 and had wait a while to get it because of low stock back then so I got it in November.

My phone is currently at 91% (was at 92% yesterday) with casual to heavy usage (using it as hotspot and charging a few times a week).

It was brought to my attention that the heat is what would make the capacity and battery degrade over time but for me it seems like some update might have made it worse and made my battery degrade at a faster rate maybe but not sure since it was fine for the first year and it was above 95% with some heavy usage.

Hello~ As to your question about replacing your battery… yes a new battery will be at 100%. Only have it replaced by Apple or one of their Authorized Service Providers.
