First Qi2 Wireless Chargers Coming Soon

Just to clarify, Qi2 provides no advantage over MagSafe other than the fact that:

1. It’s cross platform so an android could use it as well?
2. It’s supposedly cheaper due to not needing to pay Apple licensing fee to use MagSafe?

Hopefully cars start putting in qi2 chargers. Cars and other furniture that come with built in chargers is probably the only use case where qi2 actually impacts me.
 
Would welcome this - the magnetic connection especially - in a built-in wireless car charger pad context.

Mine is just in front of the centre console and between the slow charging, nearby metal-triggered or heat-induced cutoffs, and silently losing the charge connection almost every time you hit a slightly uneven patch of road causing your phone to nudge slightly off the coil, I rarely charge my phone in the car for anything other than emergencies.

Why would want that kind of data transfer when non-magnetic forms of data transfer already exists?

Or do you mean to combine both power and data protocols into one, but then you'd still have to have your device touching something (e.g., puck) for the data transfer to happen when you can already do this wirelessly without requirement of touching something.

THUNK is the sound you want to hear to get USB 4 data and peripheral connections while charging your phone, then the USB-C port can be eliminated.
 
I got my MagSafe pucks super cheap a few years ago so I’m all good. Wake me up when have actual wireless charging.

Do Qi 2 chargers definitely charge iPhone 15-series at the full 15W or not?

9to5mac's article said they do, but MR's article says it's unconfirmed??

First Qi2 accessories for iPhone 15 coming ‘in time for the holiday season’ - 9to5Mac

The iPhone 15 is the first smartphone on the market to support Qi2 wireless charging, and more details about what...
9to5mac.com 9to5mac.com
"Once the first Qi2 accessories are available, however, iPhone 15 users will be able to charge at 15W using any Qi2-certified accessory."

vs MR here saying:
"but it is not yet clear if Apple's iPhone 15 models will support faster wireless charging with Qi2 accessories."

Somewhat contradictory reports.
 
Hopefully iPhone 15 models support the faster wireless charging on Qi2 chargers.
 
Seems a bit late to get them out by the holiday season, at least with regards to the North American and European holiday season (they’d need to be in containers on shipping boats already, I’d reckon). Maybe, being Chinese manufacturers and a largely Chinese consortium, it’s the lunar new year that they mean when they say “holiday season”.

“Actual wireless charging” probably isn’t actually a good idea from an RF safety perspective or from a power efficiency perspective. It’s a similar issue to people who trumpet Nicolai Tesla’s power towers, 1) the power levels necessary to blanket a room or a city with wireless energy would be potentially dangerously high and 2) you’d have to be constantly generating and broadcasting power regardless of the current power load. Crystal radios can derive sufficient power from broadcast towers to run a radio (and there are some models that allow you to tune to a strong station to use as a power source for an amplifier circuit, that can then amplify weaker signals), but the power that you’d get from a 50,000 watt AM station can’t power a full speaker, crystal sets are limited to piezoelectric earpieces. To deliver sufficient power to charge modern devices from a Tesla-style power tower would probably require megawatts or gigawatts for just one device. On a room scale, you’d probably have to use hundreds of watts (maybe even into the kilowatt range).

PSA: This has been confirmed by The Verge...
https://www.theverge.com/2023/11/15...wireless-charging-open-standard-certification

"After this piece first published, Apple spokesperson Jacqueline Roy confirmed to The Verge via email that the iPhone 15 will charge at up to 15W on a certified Qi2 charger."

So now we know straight from the horse's (Apple's) mouth!
------------
EDIT: More explanation from that article...

" In addition to easier alignment, Qi2 will offer the same higher charging rates —up to 15W— to all compatible devices. Right now, iPhones can only charge at up to 7.5W on regular Qi chargers (with or without magnets); they can do 15W, but only on more expensive MagSafe-certified chargers. Android phones, meanwhile, could charge at up to 15W (but realistically 9 or 10W) on those same standard Qi chargers, including the ones with magnets, but would only charge at 5W or less on MagSafe chargers.

Only Qi version 2.0 devices with the Magnetic Power Profile, i.e. generic MagSafe, will get the Qi2 branding. According to the WPC’s press release today, the other part of the v2.0 update consists of “an enhancement to the existing wireless charging Extended Power Profile (EPP) that does not include magnets but complies with the Qi v 2.0 standard.” Qi v2.0 devices that don’t have magnets won’t get the Qi2 branding but will keep the existing Qi logo.

Paul Golden, the marketing director for the WPC, said that all Qi v2.0 devices “share a common compatibility layer” and will be able to interoperate: a magnetic charger will still charge a non-magnetic Qi v2.0 device, and vice versa. I asked if Qi2 —the magnetic version— could be added to existing Qi devices through third-party accessories like cases, and he replied, “We expect this should be possible in the future.” "

The question then is (per The Verge's article):

So what exactly is the advantage of buying a (usually more expensive!) "Made for MagSafe" product vs. a (likely cheaper) "Qi2" branded one, outside of Apple checking and certifying them?

If anything the Qi2 branded ones also offers future Android devices the same 15W charging speeds iPhone 15 or later has, while the Made For Magsafe ones only offers future Androids 5W??

"Up to 7.5W?" Yay. Compared to 35W via USB-C for my iPhone 15.

Wireless charging for my iPhone 15 is *so much* slower than wired that I have essentially given up on using my wireless charging stand.

Really... at 35Watts the battery must be toasted within the hour. I've got this cheap charging pad (branded Reload) and it works fast enough at 7-10Watt. Usually charging (on optimise mode) when sleeping. Not using the phone that much on a day (1-2 hours screen time) I hope that I get 5 years out of it.
