You mean shutdown the coil. No electric is passing through the magnets. They are only there for proper placement of the puck or attaching other accessories to.

iPhone 12 What problem is MagSafe solving?

So what happens if you use both the puck and the Lightning cable?
I assume the Lightning takes precedence.
I’m thinking of in the car where you need the Lightning cable for CarPlay but the 15W charging of the puck would be faster than the 2A coming from the car.

I think MagSafe is EXTREMELY overrated as of now. Let’s see what happens with it in the future but for now I don’t find it interesting at all.
I think what he/she is saying is that once charging stops, have the magnets de-energize and release from the phone.
That would make my setup better as I currently keep both iPhones on the single mat with dual Qi chargers that wakes me up in the morning. My setup does not stick to the phones and therefore I would pick it up blindly. I would hate to pickup the phone to turn off the alarm and have that Magsafe puck and cord get yanked from the wall each morning.
How would that work?
The magnets are needed to align the coil. How can they align the coil before they're energized?
Plus they're rare-earth magnets not electromagnets. They can't be deenergized.
You mean a pro phone that can't transfer 4K/HDR content??? Use AirDrop!
from the SD card to phone! I guess they can make some adapter that can wirelessly transmit.
I would keep your current setup and use a non magnetized Qi wireless charger. No need for the MagSafe puck.
Demagnetizing the magnets when the phone is charged would be terrible for people that use a car mount or desk mount. I wouldn't want it to just fall off the mount.
I believe the MagSafe is primarily for people who have had trouble placing their phone on the right spot using the wireless charger.
Only if you buy into the Apple ecosystem. Which is crazy. Clearly it can support the faster charging rates, just open it up.
I had been thinking about this, but it would mean that (a) the phone would fall of the stand-like chargers in the middle of the night 🤣 and (b) the magnets would have to be active electromagnets that would therefore consume energy while they are on, which would be rather counterproductive.
For most people, yes.
Wireless charging gets even more inefficient, if you don't place the phone exactly in the center. Most people will just put the phone on the charger and if it charges, they are happy. But just because it charges, doesn't mean the alignment is good.
"In the case of misaligned inductive charging, the peak temperature was of similar magnitude (30.5 °C) but this temperature was reached sooner and persisted for much longer at this level (125 minutes versus 55 minutes for properly aligned charging).
Also noteworthy was the fact that the maximum input power to the charging base was greater in the test where the phone was misaligned (11W) than the well-aligned phone (9.5 W). This is due to the charging system increasing the transmitter power under misalignment in order to maintain target input power to the device. The maximum average temperature of the charging base while charging under misalignment reached 35.3 °C, two degrees higher than the temperature detected when the phone was aligned, which achieved 33 °C. This is symptomatic of deterioration in system efficiency, with additional heat generation attributable to power electronics losses and eddy currents."
You can find several tests like that on the internet.
It’s not crazy. It’s literally one of the advantages of having an ecosystem. I have some piece of mind that if I attach a MagSafe charger to my phone it’s not going to jack up the battery after two months of use.
5 years later, still waiting for the magsafe standard to adopt pogo pins. honestly I, and I think others would rather magsafe battery packs send power directly and efficiently via pogo pins instead of wastefully trying to send power by induction which is so inefficient and causes so much heat and energy waste.
Such that it matches the Smart Connector in many modern iPads, right?
Power is transmitted through these ports from accessories used by iPads such as docks, keyboards and other accessories
I might even suggest that apple follow something along the lines of the what xiaomi is doing for their magsafe camera attachment, and integrate two pogo pins directly into the magsafe3/qi3 standard. This would allow to still be backwards compatible with qi1 and qi2, but allow much faster charging and data, while still retaining all the benefits of a strong magnetic attachment system that magsafe/qi2 offers.

So we are speculating cross charging and reverse wireless charging an Apple Watch and/or AirPods Pro on an iPhone’s back?
