Now if you could just slap one of those on the back of the phone with some double stick tape!
Should not use your device while charging…hmmmmmmm.
So what do the experts think of an iPhone sitting charging all night, unlocked, screen on and a clock app running?!
Well, I don't know, but I do know I've done that since 2009 and never had a problem.

Potential downsides..................
A whole day devoted to the endeavor, including the 4 hour round trip to the Apple Store.
A Genius Bar employee who fails to get the job done without damage or botches the re-sealing process upon reassembly.
Should they damage the phone, but not have a replacement in stock.
Sometimes it pays to be a bit fastidious about making things last as long as is reasonably possible, especially when it comes down to proper maintenance.
Or your kid, or your dog, or your significant other............🤣
That's good common sense but has nothing to do with charging.

Not much truth that. Your battery, if it becomes too warm, will automatically stop drawing a charge. This almost never happens as phones have a relatively high heat tolerance. If you are charging your phone on a very hot day in your car whilst playing a graphically demanding game, you will see your phone stop charging. There are failsafes to prevent damage so you don’t have to worry about such things.
I don't abuse my devices. Next to the Apple genius's surprise about seeing a phone with a home button was his admiration for the condition my 6s+ was in when I handed it to him.Potential downsides..................

There's also a reason why my battery on that 6s+ only hit less than 80% BY November 2021. It wasn't as if I'd been dealing with a bad battery for years at that point - it took that long to get there, I'd just been waiting for it to get under the bar Apple has for battery replacement.
As to time and distance, yeah, I know. Not everyone is close to an Apple store. But that's where you start weighing your options. One of my backup plans for unexpected stuff that leaves me without my phone is my 6s+. I went back to using it as my primary phone in May 2022 while my 11 Pro Max was being replaced. And the backup to the backup is my Pixel 3a XL. All I need to do is swap in my SIM.
But I also try and make it as easy for the Apple techs as I can. I got into iDevices in 2012. I've been to the Apple store a few times for various things. I know the drill. Backup your phone, turn off Find My, log out your Apple ID, turn off Face/Touch ID, turn off passcode, reset device. All done before you ever enter the store.
You present a fait accompli to the tech - you've done half their job, all they have to do now is theirs. At this point, if they f-it up, that's all on them.
That's extremely impressive. I usually have gotten about 3 years or so out of mine before they reached that point (less than 80% battery health), but it looks like you're pushing 5+.
Oh, it's still going.
My primary is my 11 Pro Max and my 6s+ is on a second line.
In order of upgrade…
6s+, Pixel 3a XL (screen is max brightness, which is why it's brighter than the iPhones), 11 Pro Max.
Sorry for the crappy pic, that's my 6th gen iPad taking that.
Use it and charge at night or as required.
Try to prevent the phone getting hot, excessive heat is a battery killer.
Here are the steps (no particular order):
- Use original cable and charger
- Stop worrying about the battery
- Use the device as much as you want
- Stop worrying about the battery
2 biggest things:
1. Use a slow charger (apple USB-A 5W)
2. Charge to 80% max, drop to 20% min.
This will preserve your battery for the longest amount of time possible.
HOWEVER
It will chemically age anyway, and also age from the usage.
And, take it from an obsessive nerd like me, enjoy your phone and if you keep it for a while, a battery replacement after 2 or so years is not that big of a deal.

So we can put you in the NO column for wanting Apple to give us an 80% max charge option? 🤡
I don’t care about that and would never use it. It would still be cool if Apple gave other users the option though.
After stepping around the exaggerations, twisted cherry picking, etc, the two important factors are:
The next is a multi-part recommendation:
The above situation is where the no less than 20%, no more than 80% recommendation is derived — unfortunately, oversimplified as passed along. The truth being, a 20 to 80% battery charge range is a compromised suggestion for device’s used infrequently. For example, if you had an emergency flashlight that was charged to 50% and left unused for months, you wouldn’t have a lot of functionality (i.e., half or less of the maximum runtime) when it finally was needed. As a compromise, you could charge it to 75% which is only somewhat stressful on the battery cell(s) yet still provides most of the runtime.
Back on subject:
Leaving a battery at a consistent “extreme” (near 0% or 100%) for extended/long periods, even if the device is in operation, is ill-advised (e.g., an iPhone plugged in overnight as well as during work shifts). Such a behavior is not common and Optimized Charging is designed to compensate, although, the feature won’t manage every instance.
In other words, as long as the battery cell(s) are used, depleted or charged, regularly and extreme heat is avoided, you won’t be increasing battery degradation.
==========================================
I mostly do 100% -> 0%, 0% -> 100% charge cycles. I have used Apple 5W/10W/12W, Anker 7.5W Qi, Amazon Basics 30W GaN.

Don’t worry, it’s fine.
Charging while operating can increase the internal temp further. However, for example, using my iPad to Web browse or play certain games (even just turn-based) can cause a large portion of the back panel to become very warm. Ultimately, engineers account for such behavior and thus, you shouldn’t worry about it.
Five years in my possession as of today.

I was charging my 12PM carefully for a year but found out that the battery health came down to 91% after a year of usage. As I am a heavy user, I started charging whenever I need to and stopped bothering about battery. I don't charge it overnight and turn on battery saving mode after 21.00 with automation. But my battery health still shows 91% after almost 2 years!
I don't know how accurate coconut battery is but it says 93.7% and 759 cycles.
By the way, can some one explain to me why my iPhone shows that I have used 89GB / 256 GB but coconut battery says 219 GB / 256. I do have iCloud+ with 144GB used storage.

Ignore coconutBattery’s health report, the value is for that moment (i.e., live data). In fact, you can watch the health percentage climb or lower as you charge or use the phone (disconnected from charger). Apple’s algorithm seemingly calculates the median/average.
Nevertheless, remotely near 90% capacity after that many cycles… You’re/it's doing fine.
As a reminder:

I get the fastest charger the iPhone supports and I juice that baby up when it gets low. It gets real warm because of all the power it's suckin' down and it makes me feel like a happy father with my baby eating good.
I need my phone to be usable, so I need it to charge fast when it's low. I also value convenience so I have a MagSafe bedside charger.
I just don't care about battery health. as many have said these devices are very smart, and as @eyoungren has mentioned a few times, the price of a battery replacement is not gonna kill me after 2+ years using the device. I couldn't do my job without a phone, therefore it has probably made me more than $80 in those 2+ years. Even if my phone is only used for MFA codes etc, I still probably spent at least 1 working hour over 2 years getting those from the phone 😝

Lowkey it's super satisfying plugging it into a fast charger and see it go from like 17% to 70% in no time. People don't know how long it took back in the 6 Plus days to charge it with a 5W brick. Screw that!
I got a Belkin 30W GaN charger right now and this thing puts out 27W for the 14 Pro Max. Since it's GaN, the brick itself doesn't even get hot and that iPhone just gets warm. Seeing people use 5W for these 2022 iPhones is wild to me lol
‘I have always used the 5 watt Apple charger. It charges all night and as long as it is ready to go in the morning, I don’t care. All of my last three iPhone still showed 100% battery capacity after one year.
¯\_(ツ)_/¯ to Each their own.
Some of us need to charge at times that aren’t overnight, and also aren’t upset by our batteries degrading over time, as they are expected to.
My release day 13P is at 89% and that’s just fine with me. I got the thing to use it!
