My iPhone 11 Pro Max battery is currently at 90 percent. Do I need to upgrade to the iPhone 12 Pro Max?!!!!
This is actually a very good result!

My iPhone 12 mini was at 82% battery health when I sold it last week. Do you have any tips and tricks on how to maintain a healthy battery?

It might also have to do with the Max battery being much larger compared to the mini.

With my iPhone 16 Pro, I've set maximum charge to always be 80% - hope this will help.

I've just replaced my 13p battery. Although the health was showing 85% it felt like it was not so reliable and the battery was draining much faster. I feel apple is doing this on purpose to feel like your "old" phone is not keeping up anymore.

The phone is glorios again and the battery lasts 2 full days!
 
Oh, and because they sold the series 13 until few months ago, theoretically we should get software updates for 5 more years from no on so is a good investment to replace the battery if you like your phone.

My own experience says that isn't the case.

It took me five years to get the battery on my 6s Plus down to 79% so I could get a battery replacement. So, October 2015 to November 2020. My 6s Plus is not slow.

I got a replacement for my current iPhone, the 11 Pro Max in May 2022 (because I'd dropped it). Two and a half years later it's at 90 percent and not slow.

Apple did deny me a replacement battery for a used 6 Plus I picked up in 2023. I got a new battery at a third party and that phone is not slow.

Of course, as I always caveat, I don't use any of my phones as replacements for computers, gaming consoles, TVs or media devices. I use them for phone calls, messaging and email and some light web browsing when I am out of the house.

I have several computers around me all day (I work from home) and my job/profession requires the use of a computer. So it's not like I need to use my phone for anything more than I just mentioned. And, it's a hassle taking my hands off keyboard and mouse to use my phone as a less capable device than the computer I'm sitting right in front of.

My experience was the same, the phone was exactly the same in terms of responsiveness and everything.

What I was trying to say, was that it felt like the battery was draining much faster/easier than what I would expect from a battery with 85% health and I suspect the battery might've been below 80% in reality (which is absolutely normal after 3 years of usage).
But, as a user, this might still make me consider buying a new phone instead of replacing the battery,

I see. Makes sense.

For me the only thing that would make me consider a new phone over replacing a battery would be if I want the new phone or iOS is out of date to a point I can no longer stand it.

My needs/use cases for a device haven't changed (much) since 2009 when I got my first smartphone. So, iOS is really why I buy iPhone. I guess that's the same with other stuff for me too. As long as I can still use things in the manner/way I am accustomed to using them, new features or the very fact that something is new doesn't have a lot of attraction for me.

There are exceptions of course. I'll go hard after something if I think it looks cool. That hasn't really been the case with iPhone in the last several years though.
 
The battery health of my iPhone 15 Pro Max dropped to 98% today due to wireless charging it everyday.

Does it makes sense to buy the iPhone 16 Pro Max?
Absolutely! You can’t go wrong with a new iPhone 🤷‍♂️😂

It would make more sense for you to see a Psychiatrist.
Have you priced psychiatrists lately? An iPhone would be considerably cheaper unless insurance covers it 😂
 
Ok, thanks all for your input. I will wait till my battery health drops to 97% and get the iPhone 17 Pro Max instead.

Wireless charging is killing my battery health so much.

I'm curious why you believe wireless charging is killing your battery? Batteries degrade just with time and use, and various factors speed up and slow down the rate, but it happens. I curious why you single out wireless charging.

FWIW, in general, I wouldn't worry about battery capacity as a number. If Apple is still updating the OS, the device runs the OS and apps without issue*, and the device gets you through the day, save your money. But if you want new features, that's ok, too.

* I planned to stick with my old XS until Apple stopped upgrading the OS. But something happened with 18. The podcast app became a huge resource hog and drained the battery rapidly. Battery capacity was at 85%, battery was (and is now) supporting peak performance, and performance overall was ok with iOS 17. I waited and hoped 18.2 would correct the podcast app issue, but it didn't. The point is the question: Are you happy with the way the device is performing? In my case, I was, even with battery capacity at 85%, until iOS 18 indicated to me the XS was at the end of its ability to keep up with the new OS, and it impacted my daily use of the device.

In these years, I never even looked at battery health until this issue started with iOS 18. I wouldn't worry about it until there is some reason to check; no reason to monitor without cause.

Just my opinion.
