Quick charging does not make your battery wear out quicker - heat does. 27w charging is probably no worse, if not even better, for longevity than wireless charging. Unless you are charging in extreme conditions (direct sunlight, 100° heat with no AC), none of the charging options will degrade your battery any faster or slower, especially considering the phone will slow charging down when it’s too hot anyway.
I have a spare MacBook Pro 96 watt USB-C power adapter.

Could I use this plus a C to Lightning cable to charge my iPhone 13 Pro Max without damaging it?
 
I’d like apple to let users choose their max charge percentage. For example, I’d prefer my iPhone never charge beyond 80% unless i choose to manually override it.
I agree. I almost never need more than 50% of my battery. I charge overnight, and use wired CarPlay during my 30-40 minute drive to and from work. By bedtime I'm almost always above 50%. I would absolutely limit to 80% on weekdays if I had the option.
 
I don't think it'll make that much of a difference because it slows the charging down the closer it gets to 100%, but I'm interested in seeing a test comparing the iPhone 12 and 13

Edit: According to this article, it gets to 48% in 30 minutes. That's roughly the same as the 12 pro max. But it's also a larger battery overall.

No wonder I noticed this thing was charging blazing fast compared to my 11 pro max on my 30W Apple charger. Confirms my suspicion ——- “damn it’s charging considerably faster”
I charge it an hour before going to bed so it’s not plugged in all night

I noticed mine seemed to be charging faster. I thought perhaps it was just me. I'm using a magsafe duo at home and an old Samsung qi charger at work. Both wireless. Just seemed like it's charging a bit faster.
 
Thoughts on leaving your iPhone in its case? Heard mixed reviews.

Personally, I leave my iPhone in the Apple leather case when charging with MagSafe.
I’ve had no heat issues with MagSafe through my leather case! Same can’t be said for my old QI charger

I've done fast charging with newer and older iPhones and none of them ever got as hot as when letting them sit on wireless chargers for a full 0%-80% charging "cycle". It really just takes some 5%-15% of wireless charging for the phone to get noticeably hot.

I can't attest to heat generated by MagSafe charging but I assume it's creates the same or more heat than regular <15W Qi charging since all wireless charging is so (comparatively) bad at conducting the electricity efficiently into the battery.

Despite reading a lot about battery wear and charging, I honestly can't grasp exactly what this heat will actually equate to in increased battery capacity over a 2-year period. Maybe there aren't any substantial numbers out there yet? But I have to think the increase in wear must be much larger from nearly any wattage of wireless charging in comparison to 18W-27W fast charging.

Yes, there's also noticeable heat generation when fast charging. But it seems to just be a quick initial burst of heat that dissipates quickly, whereas wireless charging seems to only cool off when the iPhone stops charging altogether in the 80%-100% range.

11 Pro Max could charge at about 22.5 watts. The difference was surprisingly noticeable with a 20 watt charged vs. a 30 watt charger. I never saw a formal test of the 12 Pro Max but it looked to me like it could take in more than 20 watts too. The 13 Pro Max charges blazing fast when it’s under maybe 30-35 percent, to me it looks like the fastest iPhone charging to date. Why I even care about this information who knows

PSA: If you want your battery to last, don’t worry about fast charging. Worry about the phone getting hot (e.g. being left in the car on a sunny day) and worry about how high you regularly charge it. Set up a shortcut that starts a 1 second timer after the phone exceeds 75, 80, or 85 percent (depending on your needs). This isn’t feasible for everyone but if you can prevent your phone from being regularly charged to 100% the battery will last much longer.

How to make this more feasible: use a fast charger and charge your phone right near you, like at your desk.

IDC what Rene Ritchie says. Regularly charging a lithium ion battery to 100% will make it degrade much faster than not doing that. No amount of “optimization” can overcome the universal chemistry of lithium ion batteries. Apple’s “optimize battery charging” is an overdue step in the right direction but will not help your battery lifespan nearly as much as preventing it from regularly hitting 100%. I really wish they would just let us set a maximum charge level in settings for all their devices.

Unrelated but it blows my mind the percentage of people who will buy an entirely new Apple device after the battery flops rather than just getting a battery replacement. If you cba to be as neurotic about your battery as I am and it’s significantly degraded within like, 2 years then just know that a battery replacement is an option and much cheaper than buying a new phone or laptop. Just be sure to check that the battery health is below 80% cuz they usually won’t replace it if it’s not, even if it’s out of warranty and you’re the one paying.

When I was using my MBP brick to charge my iPhone 13 Pro Max during the set up it kept saying the restore process stopped due to device temperature so I had to rub an ice cube on the back of the phone so it would continue restoring my iCloud backup.
What's the complaint? iPhone takes too long to backup and restore?
 
If that's the only difference I can live with the 13 Pro instead of the Pro Max. Upgraded to the 12 Pro Max last year because the camera was better. I definitely prefer the smaller size though. Excited for my 13 pro
There are noticeable differences. Pretty sure MR even did a buyers’ guide comparison.

That is an option on my Xperia 1 III.
Really wish that is available on the iPhone.
 
If you're going to get a 30w charger, please don't buy the giant, overpriced apple charger. The Anker Nano 2 comes in 30w, 45w, and 60w versions that are all smaller and (in the case of the 30w and 45w versions) cheaper than the 30w Apple brick.
I much prefer the aesthetic of a solid white brick with no text on it. Just the Apple logo.

To the best of our knowledge MagSafe wireless charging is the same speed as before.
 
If you are regularly charging your phone all night, you are doing it wrong. If you are regularly draining your battery below 20%, you are doing it wrong.

Keep your battery between 20 and 80%... That's how my 12 pro max still has 100% battery health still and I only use a Apple 30watt fast charger.

I feel like I was scammed with the MagSafe charger cable. I don’t mind plugging in if it charges faster. And if it is magnetically attached, it’s not much different than a cord plugged in. If there is resistance when disconnecting, don’t see it on the same level as a charging pad.

Or just use it as you’d like, charging when you’d like, and it will still last 4 or 5 years before you need a battery replacement.

I set up a notification that i get on my Apple Watch when the charge level hits 80%

Thanks for sharing I’m gonna move to that cuz the iPhone alarm at my ringer volume is a little jarring.
