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

LOL you're right, I was ranting and venting when in a poor mood, not acceptable to do in public :) and I should have them test it. and of course i did that after saying I'd had 30 years of great apple experience. now that i think about that, that's buffoonery (sp?) and if a moderator is reading this, you can delete my original post, or if I can figure out how to I will.

In a month or two when it is down to 80%.

Apple generally will not replace the battery unless it is down to 80%, but if you have an authorized Apple service shop nearby, you could ask them about replacing now.

You can find a list of authorized service shops in your area using this link: Find Locations

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.

Yes, you should replace your battery whenever your iPhone begins to experience delays, overheating and overall performance is suffering.

Apple will only replace the battery if 1) it's under 80% capacity or 2) they can diagnose other issues.

You can replace your iPhone battery once it reached 80%, but if it’s worth to replace battery or not? It depends, as the software updates, its load on device increases, so battery and all device’s components have to work hard to meet that load which reduces maximum capacity of battery quickly. For example, I have an iPhone 11 which was released with iOS 13 and device was Able to keep up with software load, but now it’s iOS 17 and iOS 18 is coming soon, so they are more heavier for system. Even though device is compatible for iOS 17 or 18 but still device’s components work hard and battery automatically works hard to meet those demands so it’s affects it’s battery life. This was explained to me by an apple support advisor.

If you find it isn't lasting you long enough especially, you should replace the battery now. Apple classifies 80% health or over to be healthy, so it would be advisable to replace at 80% if not now.

But I would also strongly recommend getting the battery replaced by apple as third-party options could be risky or just not last as long.

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

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%.

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.

I was trying to get an idea on the battery like mine is at 83% still after two years and I’m concerned about if I’m gonna have to replace it from what I just read. I believe that they would do something like that. Keep your phone percent at 83% so you would have to buy a new one I hope that is the case with me but he said he had it more years so thanks. I still got an idea.

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.

At this time battery life is 89%. Its far away from what i expect after les then year using. There is no way that my iphone will last with 80% for next one year. Thats why i wrote that is almost 80% i read somewhere that iphone should last for 2 years with 80% battery.

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.

I cant see any reply from that name, acutaly i cant see any reply just from you. I am using it for 11 months and I am not using 5G just LTE and not using max brightness, I am trying not to charge over night but in daytime to not overcharge. I have turned on optimalisation charging and still this percent of battery life. I am just disappointed because thats my first iphone. My ipad and macbook do not have that bad battery and my friends iphone also dont have that bad battery health.
