What ever happened with those true wireless (over the air) charging rumors from a couple years ago?

I don’t get the fascination with wireless charging. I can either plug in a device so I can lay a phone on top of it to charge or I can simply plug the phone using its charging port. At least with the charging cable connected you can pickup the phone and use it and make calls. Now wireless charging would be a neat idea if I can use the phone and charge it without having to lay the phone over a charger.
I thought the same way, before I got my iPhone 8. What you’re missing is a paradigm shift - the act of charging changes character. Before, I would have to do some nominal planning to charge my phone: “I’m going to charge it now”, or “I’m going to charge it later this evening” or some such. But now, with Qi charging, I don’t have to plan to charge - I just set my phone on the stand (which I would do anyway) and it’s charging. You make a big point about “at least you can use the phone while it’s charging”, missing the way it actually works - yes, when I pick up my phone for two minutes to do something, the phone isn’t charging. But as soon as I set it back down, it resumes charging again. At any given time throughout the day, my phone like has more charge on it than yours does. Wireless charging removes much of the worry about charging, because you’re so rarely running on a low battery.

My biggest issue with wireless charging at this point is, I’m annoyed that my iPad doesn’t have it, and I still have to think aboutl and plan for, plugging it in.

As long as we keep a sense of scale: using wireless charging once per day instead of cabled will add around 3 kWh per year to your usage. Average power usage per household per year in US is 10.000 kWh. If you want to save the environment, how you’re charging your phone probably isn’t the first priority. For comparison, in Denmark that number is 1.600 (sorry that was per person, actual number 4000)

edit: Another comparison: wash the dishes by hand instead of using the dishwasher once every quarter, and you’ll have saved what compares to the excess charging electricity...

In theory vs in practice can make a big difference; inductive charging consumes about 47% more energy compared to conventional cable charging, for other devices this number can be even higher due to bad alignment with the charging coil.

Additionally, "keeping a sense of scale", the adoption rate of new iphones is very high, so although the amount of power will be negligible when it comes to you as a single person, multiply it by millions/billions of people and suddenly it's a much bigger problem. And for what? Because one cannot be bothered to pickup and plug in a cable????

And then we haven't even talked about the heat degrading battery life, adding to the pile of e-waste

Considering you can get an hour extra on the AirPods Pro with about 5 minutes wireless charge. The reverse charge is defiantly worth it. And will barely use much juice from your iPhone. So it's not idiotic, and will be a lifesaver on the go.

I've used AirPods every single day since owning them in 2017. Not once did my AirPods case ever run out of juice. My AirPods 1 battery case is coming to be 4 years old now and I've yet to experience completely depleted batteries from all of my AirPods and case, despite the battery capacity being severely diminished. I've even solo-traveled with them last year where it got heavy 16-hour day usage (had to charge one in the case while using the other in the ear), still never encountered complete 0% battery in the case.

Of course I'm only speaking for myself, but I believe people are not encountering that situation all that much.

HOWEVER, I do think there is one use case where it may be useful: charging both the iPhone and the AirPods with one cable/one charger while traveling so you don't need a multi-usb charger or bring extra cables. But if it means Apple has to implement extra hardware to do so, I don't think it's worth it. Apple has never really designed iPhone for "just in case scenarios" that involve extra hardware. Hardware has always been "what you absolutely need" and the rest is done in software.

Return it. What a joke.
Easier said than done with apple’s current policies, my Genius Bar appointment is at the end of the month October 30th For My magsafe, i ruled out my iphone 12 pro, because i used two iphone 12 pros and same issue happened. Both never went about 2.94W. Can’t do walkin appointments, BUT the senior tech rep i managed to talked to did instruct me to make a sales appointment(which i have for tuesday), bring in the magsafe charger and 20w for an exchange If possible.

THey mentioned the DIY option but it would be same turnaround time if i would had waited for the magsafe charger via the Genius Bar appointment.

I don’t think a firmware issue could fix this, since outputing the same 1-3 watts consistently, so be apple or android device, it might be a hardware defect all Together or the coils not giving the right watt output at this rate...

These wireless chargers are such a waste of electricity, so much is lost in just heat...
We're talking about single digits of wattage not going directly to the phone. So yes, that lowers efficiency and does end up as a very small amount of heat. About the same as a typical modern LED bulb. But compared to using a toaster, electric dryer or over, it's pretty much nothing. You will never see the effect of an "inefficient" wireless charger on your electric bill...

I am confident that Apple is being made aware of this problem and they are working on it. They'll make it right just like they have done in the past, and if not, then you can complain about it. Just wait people.

I am more disappointed that I will have to pay for this magnet wireless technology when i buy the phone, then pay extra $40 for the charging pad to use...but in reality all I wanted is a bigger longer lasting battery that charges quickly and reliably via USB-C

I used to think this, but once you get used to just grabbing and going, especially if you're constantly walking to and from your desk at work and have to keep your phone with you, it's pretty addicting; especially when my desk has an inclined wireless charger... so I have my phone there and when an alert comes in, thanks to Face ID (which I still generally prefer Touch ID), I can just look at it and check the alerts without having to reach for it.

Total first world "problems", but handy nonetheless.

but Magsafe is not grab and go, its magnetic, you need 2 hands to de-attach the device

If you put the iPhone face down (on a soft surface) and the MagSage on top, then it is indeed grab and go one-handed.

Good video review on charging wirelessly for both iPhone 11 and 12 with various wireless chargers (including the new MagFail charger):

Well, this may be the case. But I love my MagSafe. Hitting 15w and able to hold my phone a lot more naturally compared to a cable sticking out. I for one will not returning mine. Love it

What do you mean by hitting 15W and how did you measure that?

My case and Airpods have been low on juice several times for me. Sometimes I just forget to charge the case for days. Ironically, when I'm traveling far, I seem to keep tabs on the charge.

I don't see any disadvantage from it. Don't see it affecting pricing nor the thickness of it. And with the iPhone 12 lineup, Apple hasn't introduced any REAL necessities, besides much better low light shots.

I tried talking to two different Apple reps but they were not educated on MagSafe at all. Apple: Oh yes it supports 50% charge in 30 minutes for both iPhone 12 and iPhone 11 @20W. Me: iPhone doesn’t support MagSafe only Qi at 7.5W. Apple: ...let me transfer you

Like I said, Apple never really implements just-in-case type of hardware inside the iPhone.

I don't see any disadvantage from it. Don't see it affecting pricing nor the thickness of it.

Needs extra power connectors for bilateral charging and extra QA testing heat dissipation would be big factors on a large scale (perhaps a design and/or material change would be needed to accommodate two phones getting hot on top of each other while the bottom phone is plugged in ).

And with the iPhone 12 lineup, Apple hasn't introduced any REAL necessities, besides much better low light shots.

- Apple is developing realityOS, so lidar/U1 will play a critical part of Apple's ecosystem
- 5G for longevity of the phone and affects daily usage
- MagSafe is, in my opinion, to prepare for the inevitable portless phone future. you can't just introduce a phone without a port and expect everyone to switch overnight. this is a necessary transition step.


maybe you can argue ceramic shield and water proofing are just-in-case design features, but those deal with life or death situations of the device. lack of battery is not going to kill the device.

Just like the butterfly keyboards that took many years before Apple admitted it was a failure?

Ironically, this doesn't work with the MagSafe Charger because you have to use 2 hands to attach/detach the magnets.

Might as well just use a lightning cable in that case.
