Here's What You Need for iPhone 16 Fast Charging via MagSafe or USB-C

Slower the charger, less stress / heat on the battery and such for overall longevity. I still use an old USB-A brick from the iPhone 7 era, and a USB-A to C cable. My iPhone 15 Pro still has 100% capacity after well over 250 cycles and nearly always charging to only 80% max.

I also never did inductive "Wireless" charging with that phone. Too much loss, heat buildup is also not great for the cells.

Let me ask you this, why do you care if the battery life gets low?
You live every day with only 80% max battery.
If you charge it to 100% every day for 3 years or so you still would have at least 85% battery life in my experience.
That means you'd have at the least an extra 5% battery capacity...and at most an extra 20% battery capacity.

A lot of people do care about their battery and don't want it to die after 2 years. Also a lot of people don't need 100% every day. Me for example, I have enough with 15%. So why stress my battery more than needed?

I have never come across a company more than apple where if you were to explain to your friends what all of this means you absolutely just couldn't. Frankly they are the most penny pinching absolutely good damn frusting company I know. I was so amped for them to give us 45 watt. And talk about E waste. The included cable isn't a 3.0 capable cable? Are you kidding me? Idk why this makes me so upset but hearing the included cable is 2.0 and their talk about being eco minded company is two faced. Because now you have to buy a new cable. And I'm just sick of it year after year after year. This is 2bwha cable! You need the sx123 one! Insanity. DONE

I'm sure Apple has the data on how many users connect their iPhones to a PC and how many are transferring data. Out of everyone in my family, I'm the only one that does this and I really do it to update iOS because I don't have enough storage.

Now, of the ones that do transfer data, do they need USB 3.0 speeds? I've been fine with 2.0 speeds for the last 15 years. Would 3.0 be nice? Yeah, but not necessary. But the extra cost (~$10 retail, so maybe $3-4 cost) can be a big expense over all iPhones.

I'm curious how many users even use the cable that comes in the box. I bought a few Anker cables years ago and I don't think I've used the included cable since the 4S.

Well I am a gadget guy, part of a bigger gadget family with many older devices that still get regular use (apple, non apple, digital cameras, vintage games, etc).

I care because I keep devices for a long time through family, as backup devices, or after family is done with them some end up in my personal collection. My mom has an Xs Max she doesn't need to charge every day, and it still has the original battery. It is coming back to my collection as she is getting a gently used 15 Pro Max this year.

In the family we still have a 2015 15" MacBook Pro, 3rd generation iPad, 1st generation iPad Pro, and many older iPods all with great working and original batteries.

My 15 pro sadly just changed from 100% to 99% battery health. I am okay with that, it has seen some heavy use in the past year with photo / video editing on the fly.

Other phone brands have the ability to switch off fast charging and wireless fast charging in settings. Doesn't make sense why Apple hasn't implemented something similar yet. That way you can just use whatever brick you want and not obsess about battery care.

I have Bose, Dewalt, Samsung and Pixel devices that I've fast charged since day one for over 8 years and they're all performing fine. I care more about the battery in my UPS and alarm system more than the phone.

Based on some of the signatures I see here you guys don't keep them long enough to experience significant degradation anyway.

Gotta save something for iPhone 17. The 16 just isn’t smart enough to handle something like that.

Technology improvement ≠ obsolete. You can charge your iPhone just fine at 15W with previous MagSafe chargers.

I use a wireless charger on my nightstand that does 7.5W and works perfectly overnight while maintaining battery health and lower temps.

In your scenario, if you use only 15% worth of battery a day, why worry about the state of your battery at all? No matter how you charge it year after year, you'll maintain enough battery health to get through a day until your phone is obsolete.

In short, on my iPhone 16 Plus I will either use a USB-C charger with rated at around 20 watts or use a USB-A charger rated at 12 watts/2.4 amperes. My only concern is that it could take over an hour to charge a 4,674 mAh battery from under 20% to 85% charge limit on the 20 watt charger.

For charging, at night anyway, who cares? I use a 5w, not because I'm trying to save battery health, it was just handy.

I plug in and goto bed. I wake up and it's charged.

I just checked, he says he is using the tiny little 5w that came with his iPhone 5.

I will say my 16 Pro is completely charged overnight with the 5w cube. I have zero interest in fast charging, personally.

Has anyone tried to double charge with the USB-C and MagSafe for a combine 55W charge? I’m just wondering if that’s possible.

Have always been the I only use the white cable type of guy. And am the most loyal customer and use only the included cable. And wanted only apples accessories cases etc apple brand. By the time I got a new iPhone I would use that ones included cable. And keep the old one. I never had one break. The white cable was always sacred to me. So for me this bites and is annoying. Because I'm not the casual user but I am an apple die hard fan. I will NEVER use a non white cable. Also now that USB C is in iPhone I will now be investing in a really good (black humph haha! thunderbolt 5 cable) and never deal with apples antics again.

Ok but how much data are you transferring? Will it really add that much time to your workflow? Could you do it over Wi-Fi?
 
Shame they changed the dimensions on the new 25w MagSafe charger so it's now a hair's thickness smaller which causes it to fall out of holders without a phone even attached, where as the original one fitted very snuggly.

Ended up gluing the 25w MagSafe charger into my old holder as I have no intention of removing it anyway and it's working well and so far staying firmly in place. Why they needed to make it smaller and break compatibility I'll never know.

Can I look at an Apple MagSafe charger (out of the packaging) and easily tell if it's 15W or 25W?

You can thankfully, the old Magsafe uses the plastic material on the lead, while the new 25w one is a braided cable so it's very easy to tell them apart just by looking.

It's ridiculous though that they kept the same name, MagSafe 2 would have been fine. But knowing Apple I'm surprised they never called it MagSafe Pro or Ultra.

Why does magsafe get to do 25 watts but qi2 can only do 15 watts. not asking from a business perspective, as I guess it benefits apple. More asking from a technical perspective...when will qi2 get 25 watt charging for all phones? Although i suppose androids would have to start incorporating qi2 directly into their designs? Or could 25 watt qi2/qi3 charging be achieved just with a magsafe case, even if the phone itself doesn't have the magnets...?
