The small battery of 12 series is difficult to power the phone itself, how can it support reverse charging?
The battery’s are fairly big. The mini is the only small one. Can’t change physics.

They didn’t add 120hz refresh rate cause of battery drain too much so revers charging wasn’t happening. Plus it really doesn’t work that well. It goes at its slowest speed and is not practical. Will barely be used.
That’s speculation. We don’t really know why they didn’t include ProMotion.

Consider this:
Phone in pocket charging your AirPods.
Phone plugged in on hotel nightstand and charging your watch

Obviously we wont be charging large devices with a phone, but it does have some use scenarios that may come in handy for small battery products. So if the feature exists already then why not release it.

Actually we do. it worked fine, it drained too much battery along with 5G and since they didn’t make the battery bigger it was a good option this year.

Also Samsung couldn't make enough ltpo displays to help battery life due to high volume so they skipped using it on normal panels
 
Stop believe in every rumor. If you’ve followed MacRumors for more than a year, you’ll know that rumors are just rumors.
I apologize is this is a duplicate but I couldn't find it in search. The rumors last year indicated the iPhone 11 was mechanically capable of reverse wireless charging but it was turned off in software. I didn't see any mention of this feature yesterday for the iPhone 12s, did they scrap this feature entirely or did I miss the mention of inclusion?
 
It’s sooo bizarre that people latch on to a Must-have feature that isn’t practical or efficient. Put this reverse charging idea to sleep. Apple went all in on MagSafe charging. I promise you it will never see the light of day on Apple products. Go to android where they half ass everything and put in a ton of useless features nobody will use

It makes sense from a user convenience standpoint but not for Apple. Why bother with the hassle and expense of implementing reverse charging *and* lose out on selling overpriced watch charging pucks?

Ahhhh the sarcasm. If you’ve ever owned a business you would think it’s smart and wouldn’t even point it out. Companies/corporations are always seeking different ways to grow their bottom line. its apples product. it Only makes sense they wouldn’t lose out on ways to make income By removing The headphone jack that wasn’t proprietary and neither was usb-c. They made out on AirPods and lightning cables. And now you have charging pucks

Also consider that Apple is possibly looking at doing away with the charging port altogether and MagSafe may end up being the default way of charging your iPhone. Where are you supposed to place your AirPods or Apple Watch then?

Maybe Apple isn’t implementing it because the concept isn’t going to be viable in another couple of years?
 
Is that even efficient? Do we have any numbers as far as how long it takes to charge the device using reverse?

No, and yes - not apple numbers, but I definitely saw real world samsung tests. Unsurprisingly, it's woefully inefficient and slow. Look some samsung numbers up for yourself, but ones I saw went along the lines of 100% phone + 20% phone plus an hour in good alignment = 60% phone and 30% phone. Someone's probably done the maths as to whether higher power/faster is more or less efficient, but would require more engineering and possibly more space/mass.

A friend needs 1% battery just to be able to retrieve a number from their phone to make a call ? That'd be a really nice thing to be able to do, if no one has a cable. But it won't let you give your mate 50% charge over a beer (unless you drink really, really slowly) and if you didn't just charge your phone, you're going to want to find a charger soon too. Easier to beg/borrow/steal a wire and either a powerbank, a wall charger or a laptop usb port in 99% of situations, and if you find yourself in that situation often (either as the one in need or the helper) you should probably pick up some cheap cables and little power banks to lend.
 
It's wasteful.

Yes, not very efficient but could be very handy in a pinch. I responded to you also because of your avatar. v2v (vehicle to vehicle) or v2g (vehicle to grid) has also been rumored from Tesla for a while, but they haven't added it for some of the same reasons. Although I'd see it as a great feature to be able to charge a stranded Tesla away from a charger, or to use to power my house during an outage (power walls don't make sense for me with having solar and net metering). I was also just reminded of that seeing the Roadie on Shark Tank which is a portable charger. Wouldn't necessarily be needed if Tesla's could do v2v. I had both a 3 and a Y, although sold my 3 recently since my driving went down so much there wasn't a need to have 2 vehicles any longer.

Sorry dude I’m not gonna let someone lay their phone on top of mine for inefficient charging. No matter how hard you’re trying to sell it. Apple will never implement this silly feature. It only belongs on crappy android phones
