iPhone 15 Might Support Charging Speeds Up to 35W

[rjjacobson]

I thought I would like this, but I had to disable this, my schedule means that 3 days a week I wake up earlier than than the other 4, and my phone would only be charged to like 70 % on those days. AI sucked at figure it out, it was always the same 3 days and always the same time, and I walkways had an alarm set. Should have been pretty easy to figure out. Had to disable it.

Yep a variable schedule is a pain with the optimized AI thing it just gets confused. It works if you get up around same time all days but it does not figure out after a week or so such a variable schedule it seems set only for 24 hour learning of your schedule assuming most days the same

Good to have faster charging speeds

My girlfriend's Xiaomi 12s pro came with a 120W charger in the box and she uses a 60W one to keep the battery safe. No noticed degradation after ~8 month of heavy use. My iPhone 12 pro max charges laughably slower. Apple is not even in the same league.

 

[haruhiko]

As long as I can use USB C, I don't care if the max speed is 1 watt.

Don’t give Apple ideas.

I think the folks citing slower overnight charging in this thread are missing the point of a fast charge; it's for when you need power during the day and can't wait for an overnight charge. Surely there is a time and a place for both charging methods. I would never throw my phone on a fast charger overnight because it makes almost no sense. But if I am at 20% mid day and I have 10-15 minutes to charge, getting that extra power ASAP when I know I am going to need it is invaluable. Having said that, allowing software limited charging would definitely be a useful feature. Apple already does this to some degree with "optimized charging", but I would say limiting wattage would further benefit some users, especially those of us that keep our phone for 4-5 years.

Letting users manually set when the battery needs to be full would be ideal. iOS simply looking at what an alarm is set to would work as well. If I usually need my phone by 8am but I have an alarm set for 6am one day, making sure the phone is ready to go by 6 seems like a a no brainer for most such situations.

We defend it because it's a better physical port than USB-C or USB-B or USB-A.

Only advantage to lightning at this point I think is the solidity/sturdiness of it , nothing else!

Correct me if I’m wrong, but is the USB-C so bad in quality compared to lightning?

I bought my iPad Pro 11 2020 when it was new and have been charging it every other day or sometimes every day, for 3 1/2 years.
I don’t think about to be nice when I put in the charging cable, and to this point there is no physical damage in the USB-C connector.

I can’t compare the USB-C with the lightning connector in terms of time, because the longest time I’ve been using an iPhone is for 2 1/2 years.

Guessing there is a lot of people out there to complain about the bad quality, but I don’t know what they are doing.
Maybe they using brute force😁

Ironically, the MFI program might be necessary for compliance with the upcoming EU Cyber Resilience Act as it is a way for Apple to help secure devices from USB-based attack vectors.

How will other manufacturers cope with the law then? Isn’t iPhone already compliant? They ask for trust before connecting devices.

Yes, something like AlDente for mac would be great to have on iOS. Then you could leave your phone on the charger at the office. It could stop charging at 75% and then only use power from the charger.
That way you'll only use the battery while on the road.

And yes, I'm such a 'precise' charger who uses the lowest charging currents possible and tries to keep battery level between 50 and 75%. This results in a iPhone SE2nd having a battery condition of 90% after 3,5 years. Even my first gen SE is still at 87%.

 

[3530025]

sure, wireless is not as efficient as wired, but MagSafe is probably somewhere around 90% ... and wired is 100% either, more like 96,96% ... whatever, 35W will produce more heat than wireless MagSafe ...
Thing is, all these manufacturers have the actual data (losses, heat etc etc) but its kept under the wraps, convenience (of wireless charging) outweighs the "waste" ...

You are quite wrong here.
Magsafe efficiency is not higher than 75%
(source: https://discussions.apple.com/thread/252145374?answerId=254077476022#254077476022 )
This is not something that manufacturer have to release, you can quite easily verify this yourself through measurement of input power VS battery capacity (which you can get pretty reliably through coconut battery for instance).

Non-magsafe wireless charging efficiency is around 50% for comparison.

Your 90% numbers are from the another planet and impossible to reach.

I’m old school. I prefer a classic 5W Apple Charger. Slow charging (overnight) is the best 🔋

I wasn't able to find one anywhere so I'm using a 20W charger. Not planning on switching to a faster one until it breaks and becomes obsolete.

 

[cdrider]

They need to have an indication when fast charging is happening. Bring back the double chime or similar.

Yeah I agree.

I charge my 14 Pro Max overnight on a slow MagSafe charger.

 

[Azzin]

And yet some people here will still defend the lightning port

I’ve said multiple times, that IMHO, the physical design of Lightning is superior to that of USB C.

I’m purely talking about shape and design here, not charging or transfer speeds.

If Apple gave up MFI and gave away Lightning as the standard, I’d much prefer that.

 

[Azzin]

Wow! I thought I was the only one…or one of the few.
with USB-C can you even still use the old 5w charger?

You could put a C to A adapter on and plug that into the 5w plug.

Not buying it. Ever since the iPhone 4S, I was still experiencing bad battery after just 2 -3 years and it was only with 5w charger. So no, I'd rather have fast charging instead. You don't always run on peak power. Only 20 - 80% runs at full speed while the rest is easy trickle charge. So why not just enjoy fast charging to the fullest?

 

[Azzin]

My 14 Pro Max…

I would rather prefer Apple putting larger batteries in and would take extra weight and thickness as a trade-off.

This would allow us to charge it slowly overnight just once, instead of numerous higher-power injections throughout the day. This could improve battery’s useful lifespan, I guess.

Sure you can, you might just need to find an appropriate cable or adaptor.

The EU legislation requires USB C and USB PD support, which may not be hindered by other standards etc.

Yes, but it also does not allow crippling the standards or limiting the USB PD current using proprietary certifications and chips. It is specified in the annex of the regulation. And while I'm not lawyer and I'm not sure whether there is any loophole - I know EU stance to this stuff, because they already sent message to Apple, that they will act if they try something like limiting the USB PD functionality.

EU Warns Apple About Limiting Speeds of Uncertified USB-C Cables for iPhones

Last year, the EU passed legislation that will require the iPhone and many other devices with wired charging to be equipped with a USB-C port in...

www.macrumors.com

(I specifically choose not to call MFi "standard", because it is not industry standard - it is proprietary Apple lock-in)

USB PD isn’t dumb, actually, and does use data pins to negotiate voltage and current, as well as talk to the cable in case of higher charging rates. However, these are separate data pins, not the regular USB ones.

Thank you for the clarification. Your are completely right - however the important note here is "these are separate data pins, not the regular USB ones" which proves my point that EU Cyber Resilience Act is irrelevant in this case, because USB PD is not potential attack vector.

 

[falkon-engine]

My usb4 cable supports 240W charging, and when paired with my 140W usb-pd 3.1 charger, charges my battery at up to 140W. It is not a Mfi cable. So if apple limits its charging speed on the iPhone 15 series, we will know it is an artificial limit.

 

[jaworq]

500 watts and later people cry that their phone is at 89% battery capacity after just 1 year of usage xD The slower we charge our phones, the longer battery lasts. Less heat generated etc.

 

[w_aldo]

It’s nice to have faster charging, but with battery life so good on these modern iPhones, you’re better off charging at 5w overnight. Keeps heat and battery degradation low.

 

[MilaM]

Apple has the following to say about the durability of its batteries:

"A normal battery is designed to retain up to 80% of its original capacity at 500 complete charge cycles when operating under normal conditions."

This is roughly what one can expect when (ab)using the battery with fast charging and overnight charging (long stretches of time with 100% charge).

If you're the type of person who likes to take care of your gear, it's very likely possible to extend the lifetime of the battery significantly by avoiding fast charging (heat) and by cycling the battery between 20 and 80% most of the time.

That’s exactly what I do. I charge at night on 5w. Very rarely do I need a boost during the day. That mostly happens during trips.
