I have no idea how fast my duo charger charges my iphone X.
It is magic! I put it on before I sleep, wake up and it’s fully charged!

on very rare occasions i wake up at night wondering if it charges quickly enough just in case I need to edit a video at 3am on my phone while doing a facetime call.
 
Yeah, that’s a misconception Apple sold to defend low-watt chargers.
Have you not considered why they’ve finally climbed on board the high powered trend now?

Linus did a great experiment to see if low watt chargers were better for you battery in the long run, and yes, while they give off less heat, they require 4 times as long to charge than a higher watt charger would need, meaning you’re heating your battery for way longer than necessary.

Also, isn’t the point of a mobile device supposed to be that it’s wireless? What good is it being plugged in several hours a day?

I’ve been charging my phone using a 35 watt since it could take in that amount of energy, and I’ve noticed my batter hasn’t aged any worse than my older iPhones that were stuck to the 5 watt chargers for way longer.
They're selling high-powered because the marketing benefits outweigh whatever flak they're gonna get, plus concerned customers still have the choice to slow charge. When fast charging was a new thing, it was known to be harder on the battery. I'll bet Apple has done a lot of work to mitigate that kind of damage, but I doubt it's the same as slow charging. And if the batteries last a year less, maybe that's a good thing for Apple.

Re heat: It's going to be pretty much the same amount of aggregate heat no matter what. That's not the point. Peak temperature matters too, as does charging speed irrespective of that. There's a reason trickle charging is a thing.

You're comparing your brand new iPhone to the older ones. I had the same 6 forever until ~a month ago, and the battery held up. Given how notoriously bad the batteries are on these, that's a good ending. Doesn't bother me that it touched a wire either. I slept, and it charged.

I find it more remarkable, that apple recommends the Magsafe Duo to people like me, with an iPhone 8 Plus. But it is useless because apple limits the charging to 1-3W with an 30W Brick. A whole night is not enough time to charge the phone. But no one cares.
1-3W doesn't sound right. The slowest possible way I could charge my iPhone was 2.5W = 500mA * 5V. A brick is going to be at least an amp.
 
personally a faster wireless charging would be nice when:

Apple implements a vapour chamber to keep the device and battery cool from over-heating which leads to poor battery life and capacity longevity. Until then 12w is fine by me.

looking at my 8mths old iPhone 12 mini that I mostly charged over MagSafe and my battery health drop, I’ll be much smarter using Lightning on the 13 mini going forward.

Damn... my launch day Mini is down to 90%. I never had an iPhone drop that low so fast.
Also the first iPhone i'm charging wirelessly.. hmm...

It is pretty slow. Even apple support document state, that Magsafe charges QI Devices slower

Just looked at my old posts on another forum. My iPhone X still had 98% after 1.5 years!

Don't rember what it was at when i changed it for the Mini though.

In prior years, my battery health has been 98% or such when I make use of the iPhone upgrade program. This year, it’s at 90%. The only difference is I’ve been using fast chargers this year.

I may go back to the good ol’ 5 watt wall wart with my 13 Pro…
 
If you are in a hurry to charge it then wired charging is what you want. MagSafe is perfect for charging while doing work or sleeping. If you are going out and need your phone charged pretty full and fast, go with fast charging and one of the Mac chargers. I have an Anker USB C car charger and that thing is insanely fast.

As I mentioned, I've tried both (MagSafe AND wired through 20W USB C adapter) and didn't see much difference.

I've been using MagSafe 99% of the time with my 12 Pro that I've had since April and my battery health is still at 100%

I forgo wireless entirely and charging only with wired now. 6 months on and my battery is still at 100%.

When your battery degrade, if your phone new and battery at 100% its hard to notice it but when battery at, says, 85% then it will degrade substantially. So all wired now.

thats great and just to check that health is checked with charger disconnected right and a reboot just to triple check? Curious at what battery percentage do you charge your device at?
Thanks.
Lucking you. I’ve been using my Belkin 3-in-1 MagSafe.

I just restarted my phone yesterday (because an AirDrop issue) and it wasn't connected to a charger when I checked.

Mac chargers are much more than 20w. Try 85 or 100w and it’ll be much faster.

From what I've read, iPhone can't charger faster than around 22W, so if you think your 85 or 100W charger is charging your phone faster, then it's likely the placebo effect.

You’re right, it requires a minimum of a 18w adapter but higher wattage adapters don’t go any faster. I can say it is definitely faster than MagSafe, at least for the fast charging part.
 
Lol read this again after a few days and I’m gonna steal that: donut care!

I know it’s a typo but it just works lol.
lol no I typed that on purpose! It felt somehow less snide than saying I don’t care because I didn’t want to actually disrespect people who feel differently. At least that’s how it works according to GrumpyMom logic. 😆
 


While Apple's standard MagSafe Charger can typically support up to 15 watts of peak power delivery to iPhone models when used with an appropriate power adapter, last year's iPhone 12 mini was limited to a lower 12-watt peak, perhaps due to thermal constraints with the smaller device.

As highlighted in an update to Apple's support document on the MagSafe Charger today, that restriction remains in place for this year's iPhone 13 mini, similarly subjecting it to the lower 12-watt limit. Given the nearly identical body size between the iPhone 12 mini and iPhone 13 mini, it's not particularly surprising that the limit applies to both devices, but to our knowledge this is the first time Apple has confirmed it.

An iPhone connected to MagSafe intelligently manages its power draw to prevent overheating, and thus even a fully supported model capable of charging at 15 watts may see much of its charging time spent below that threshold in an effort to protect battery health.

The smaller battery of the mini-sized iPhone models also means that they require less energy to recharge than larger models, so an iPhone 12 mini or iPhone 13 mini capped at a peak of 12 watts may not take any longer to charge to full via MagSafe than an iPhone 13 with a 15-watt limit. Still, users should be aware that this restriction persists with this year's mini iPhone.

This isn't the only MagSafe-related topic making the rounds today, as it's been discovered that the iPhone 13 Pro with Apple's standard case on it doesn't sit quite properly on the MagSafe Duo Charger due to the size and height of the lip that protects the rear cameras. Despite the fit issue, the phone seems to make a proper connection and charge normally.

Please Apple, keep making iPhone Minis in future generations. The 13 mini is easily my favorite iPhone I’ve ever had. The form factor is ideal, and the improved battery life is essential. The screen real estate is sufficient, and the weight in hand is not overbearing. I’d prefer the second camera as a telephoto lens as opposed to the wide view, like the iPhone X, but this isn’t a deal breaker.

Mini lovers, speak with your wallets. This is probably our last chance!
