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

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.

Sounds really good. Could be 80% after 500 cycles.

Yes it is rated to be 80% after 800cycles.

I don’t think it’s fair to assume that this is standard and what happens with everyone. The soonest I have ever had an iPhone battery degrade to the low 80% range was 23.5 months (one was 82% at that point and was one that my autistic son used daily to do a lot of gaming and playing music as that is his comfort zone. The other was 81%. ). Now of course it really is going to be various different experiences others may have based on their usage and everything but to imply that there is a conspiracy to force users to buy a new phone versus replacing the battery solely off of your experience is a bit of a reach. Every other iPhone in our household has remained well above the 80% threshold with my mom’s 3.3 year old iPhone at 84% when we finally upgraded her last month.

Point being, as disappointing as your experience with your iPhone and its battery has been it doesn’t mean that’s common. The fact that yours has stayed at the same percentage for a couple of years after reaching 83% seems to imply something else was going on making the reading not seem accurate but that’s just a guess.

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.

Don't worry too much about it! Everyone gets frustrated at some point.

I bought an iPhone 14 Pro Max on August 16 2023 so I have been using this phone for 5 months. In this period, my battery capacity dropped 1% after 4.5 months and another 1% dropped within 1 week my capacity is 98 after almost 5 months. So is that normal or something? And yes in this 1 week I used another random cable which is not from the original iPhone cable. And it heats up a lot to my charger. Was it relative to using the random cable?

When my battery is lower than 80% if I replace the battery with good quality, will it be 100% again?

98% is normal aging within 4.5 months?

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.

I've always wondered why this is the case; why wouldn't apple want to replace the battery over 80%? Surely if the customer doesn't find it lasts long enough especially on smaller models like the 12 mini or SE.. And it is extra business for them, no?

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

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.

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.
