My iPhone X has a battery health of 84% after 2+ years using wireless charging.

Now that I have picked up a new iPhone 11 Pro max, I am wondering what charging method is best for preserving battery health?

When you used wireless charging your iPhone X was getting warm?

Better question is: How do I treat my battery the way it wants to be treated so I can reduce the capacity loss over the course of my ownership?



Try to keep charge level >30% and not at 100% for long periods of time (weeks on end). Heat is a killer - don't put your phone in the car on a hot summer day (or glove box).

Five_Oh is right - just use your phone, batteries these days are pretty resilient. For something that doesn't cost a lot to replace, there are other things to worry about.

Ever since I’ve gotten the 11 Pro Max I only have to charge at night and I’m able to use the phone all day without any worries. Before with the Xs Max I would have to plug in during the day but now that I don’t have to I don’t worry so much about my batteries health.

Well I can give you the theory but I don't think it makes a lot of difference and I never do it:`

The battery has two layers and it pushes ions one way to charge, and the other way to discharge.

Therefore, it is logical that at the 50% charged mark, ions move most easily one way or the other and as you get higher charge or lower charge, you get resistance- which is heat- and this reduces the battery life.

So the upshot of this is, for maximum longevity, you keep your battery between 20% and 80%

Wired. Wireless charges aren’t worth the price to me. They also seem very slow from what I’ve read.
Very slow - but it is a convenience factor. I have a wireless charger at home on my desk that I can just lay my phone down on and forget about it. I also have a wireless charger at work.

My phone rarely sees below 90% charge unless I'm going out somewhere or doing something away from home.

My 11 Pro Max is still showing 100% and the battery seems like it could last two days at least on a charge.

I am using wireless charging for the first time with my 11 Pro Max and put it on the charger every night. My 8 Plus and probably my 7 Plus were plugged in to a charger every night as well.

I had never checked or worried about Battery Health until I went through the process of selling my old iPhones for the first time. I had a collection as far back as the iPhone 3, that I still use as an iPod in my car since snap in adapters for newer models aren’t available and while my 2009 car has Bluetooth for calls and contacts, doesn't support streaming music..

I have an iPhone 5 I use as a dedicated iPod on my main home music system and decided to sell the 6, 7 and 8’s, all Plus models I had planned to just give to my kids but they kept wanting to buy the latest models. The 3 and 5 are always plugged in. The car only charges while driving. Not sure of my Denon Receiver with an iPod dock.

My 7 Plus was over 4 years old but not used for the past two and I had reset it and needed to set it up again when a buyer wanted to now the battery health. That was the first I was aware or cared it was a thing. Battery health showed Maximum Capacity 94% and was supporting Peak Performance Capability. I did try and charge it every month or so and keep it updated when I remembered.

Then I checked my 2+ year old 8 Plus, its Battery health showed Maximum Capacity 93% and was supporting Peak Performance Capability.

I decided to stick to wireless charging as my iPhone 11 Pro Max stays cold and isn’t as powerful as the wired charging option that shipped with this phone, which is good for battery health.

I have also been monitoring the “Optimized Battery charging” feature and it does a great job despite still calibrating.

So I think the battery health should be fine after 2+ years.
