I know this has been asked a million times but it seems there's no unanimous expert opinion on this. Is wireless charging detrimental to battery health?

My Pro Max still has 100% battery health after more than 7 months and I intend to maintain that at least when my phone is a year old.

I bet you don’t use your phone much because any battery at 100% after seven months is really amazing.

This is right for older models (which you must charge twice a day) but even though you are a hardcore user you discharge this mobile once a day.

Yes that has to be the reason. I am on iPhone 7 and I have to charge the iPhone at least twice a day. Battery health is at 85 percent.
 
The answer is, yes. Nobody credible will tell you adding heat is good for a battery.

The real question is, how much does it negatively affect battery health?

My iPhone 7 Plus is at 83% battery health and still lasts me a full day hehe. Usually don't really fall below 50% on an average day.

I mostly just wirelessly charge and have no significant drop to battery health. I think it helps that Apple only allows 7.5W max so that keeps the heat down.

Why would wireless charging be of itself harmful to battery health? It's merely a matter of current flow and whether the connection is via a lightning port or induction that flow is regulated by the same circuitry in the phone. Now if the wireless charging pad overheats the phone, cooks it, then that's another matter and I can well believe the battery might suffer.

For the record, I have only had my iPhone since mid-january, but I have only used wireless charging. My reason is my dislike of the necessarily brutal insertion of lightning plug into port, I feel that could be damaging.

In fairness, most new iOS device batteries start off at 105-108% of design capacity. My Air 3 bought during the holidays is still at 103-104% with 20 charge cycles.
 
I’ve plugged my iPhone 7 Plus in every day since the day it came out and the port is still perfectly fine.
 
I use my 11 pro max all day, but I always have it resting on a wireless charger every minute its not in my hand. I've had it since launch day and my battery health is 100% still. While I use my phone a lot I'm also really OCD about the battery dropping below like 85% (i swear I'm always preparing for the natural disaster thats going to occur at any minute. Anyhow, no issues here.

I use my phone mainly on social media and video consumption (YouTube and Netflix) "moderately". I usually charge my phone after 2 to 3 days when battery drops to 40-50% using the 5w cable charger but I find that inconvenient that's why I'm considering using a Belkin 7.5w wireless charger but I have misgivings.
 
Mine (11 Pro Max) is on a wireless charger most of the time if it's not in my hand (I do use my phone quite a bit) and on a wireless charger overnight as well. Battery health is still 100%. I did the same with by X and Xs and had no issues with those batteries either. The wireless charger keeps my phone at a perfect angle on my desk where I don't even have to move for FaceID.

OP- just use and enjoy your phone. Don't sweat the small stuff, the battery percentage on the phone is not an accurate representation of the actual battery health. Realistically speaking, even if it were to drop into the low 90's, I highly doubt you'd see any real difference in your day to day usage. If you're the type to keep a phone for 3 or 4 years, okay I get your concern but after a year like you say, you're gonna be fine.

I've been charging my 2017 iPhone X for a year and a half using the Anker PowerWave 7.5w wireless charger almost exclusively and the battery is showing 91% capacity(rest of the time with iPad 12w charger). I think that's acceptable degradation in my opinion
 
I’m using 3 Samsung wireless fast chargers exclusively for about 3 years now.
I’ve used them with many devices and they were always warm to the touch, even 5 hours after the charging was complete (I’m talking about the phones, not the chargers).
Slow or fast wireless charging, same result.
Expect for the pro max. It’s Always cold in the morning, just bit warm when it charges (as it should) and the (charger) fan never spins.
The 11 pro Max is the only iPhone that i have with wireless charging, so I don’t know if this applies to all of them.

Anyway, I never had issues with wireless charging either way.
 
I use the letscom. I have the Samsung as well. I find it superior to the samsung, in terms of wiggle room for charging, and tendency for the phone to stay put. It's also flat and silent. I'm not promoting it, it's just what shows up on amazon but I was pleased.
 
I use wireless charging exclusively on my iPhone Xs Max and I love it.

NEVER going back to wires, I shudder at the thought.
 
I think the big issue here is ever since Apple allowed us to see what our battery health percentage is people have started to be overly concerned about keeping it at 100% and to be honest that’s an exercise in futility. Eventually your battery health isn’t going to show 100%, it’s gonna go down to 99 and lower. Just enjoy the phone and try not to worry about it. If you start noticing that your battery life is subpar take it to Apple or contact Apple.

I admit, I’m one of those people. I’ve never let my battery drop below 80%. And I try to keep it regulated anywhere from 90% to 95% throughout the day. My own anecdotal theory, is that I’m still performing at optimal capacity With my iPhones/iPads, due to frequent charging. Even my older iPad Air 2 is still hold an amazing charge, because I always kept it sufficient in terms of ‘regulated charging‘ throughout the years and I never allowed inconsistent environments for hot or cold, it was always in room-like-temperatures.

anyways, I would rather see the battery percentage, as just showing me an ‘icon bar’ just gives me a generality, but I am a very specific person that likes numbers.😁

I had a Battery Life app installed on my devices before Apple ever made that info available in Settings. Up to iOS 8 or 9, you could even see charge cycles, etc, same as you could with Coconut and iMazing.

If you upgrade your phone every 2 years, battery's usually never an issue unless you're prone to letting it drop to 0% frequently. On 3rd year though, that's when I typically see battery go bad quickly.

One issue is before, Apple won't replace battery if it's not below 80% yet and you could be experiencing bad battery life and random shut downs before that occurs (which really sucks).
 
I’m not surprised yours is 100% capacity. My launch day iPhone 11 has 100% capacity, and I place it on the wireless charger every night.

When I sold my XS Max after a full year of use, it was also 100%.

Wireless charging is far better for your battery then fast charging

I charge my 11 Pro nearly every night on an Anker Powerwave stand that has a little fan in it. I say nearly every night because I don’t use my phone very much in normal day to day life and even less in quarantine. I’ve gone to bed with 60%+ some nights. Capacity is at 99%. I truly don’t care what the capacity of the battery is so long as it comfortably gets through a typical day of usage for me, so that on the rare occasions when I’m hammering the battery, it will most likely survive those days too, which at this point, it certainly still can. When the time comes when it can’t manage that, battery swaps are inexpensive, especially relevant to the cost of the phone.
