This is a great move for wireless charging as a whole, but I do have to question the fine-print here. Apple owns the MagSafe patents through 2030, which means they could pull a "MFi standard" situation and charge manufacturers licensing costs just to use "standard" technology.

I'm still hopeful that this comes with no strings attached, but once bitten makes me twice shy.

Re:Next-generation Qi2 wireless charging standard embraces A... by post_break on Tuesday January 03, 2023 @03:43PM (#34237721)
Reading the press release it appears the WCP is adopting the alignment via magnets as the standard. And Qi2 will remain the standard with no gotchas.

Once you agree to make your patents part of a standard, the standard committee forces all patent holders to license their patents under FRAND.

Yep. Historically though, Apple's standards have been less about creating convergent technology and more about reinforcing revenue streams. Look at the entire MFi line, a 'standard' that was defined by high-margin Chinese junk that slapped Apple icons on their Bluetooth smart speaker. There wasn't a Cambrian explosion of innovative iPhone tools, but instead a sea of useless iDogs and plastic boomboxes.

Apple's greed has clearly hurt their own ecosystem in the past. They've made it completely obvious that their goal is indiscriminate rent collection, and I'd appreciate if that attitude would remain isolated from the ideals of open computing as a whole.

That was never a licensed standard overseen by a standards body.

Apple contributed to the H.264 standard, and is also a major contributor to the USB C standard, as well as the Thunderbolt standard.

> They've made it completely obvious that their goal is indiscriminate rent collection, and I'd appreciate if that attitude would remain isolated from the ideals of open computing as a whole.

You realize that’s how the entire industry works right? Cellular standards and most video and modern audio codecs are also licensed via a patent pool.

There is no such thing as “open computing” where nothing is licensed from patent holders for anything that the vast majority of people would find usable.

Apple certainly has the legal autonomy to do all of this, I'm not disputing that. My point is that through these decisions, their behaviors obviously constitute market abuse. Something is gravely wrong if you can behave in the manner Apple has and become the world's largest company.
Re:Next-generation Qi2 wireless charging standard embraces A... by scarface74 on Tuesday January 03, 2023 @04:41PM (#34238491)
So is everyone else who you have to license from to create a modern cell phone also engaging in “market abuse”? Do you realize how much money both ARM and Qualcomm make from each cellphone?

Do you realize how much Google makes from the patents they bought from Motorola?

> Apple's standards have been less about creating convergent technology and more about reinforcing revenue streams

a) Apple's "standards" are not a proper standard by any definition.

b) Their proprietary connectors e.g. Lightning, MagSafe have always been developed when they have believed there was a better user experience available. When there wasn't they have adopted the industry standard e.g. HDMI, USB-C, SD.

c) Apple is a massive company that hinges on having a superior user experience to the competition. The idea that programs such as MFI would compromise this in order to create an insignificant revenue stream is illogical.

Re:Next-generation Qi2 wireless charging standard embraces A... by stewarts on Tuesday January 03, 2023 @04:26PM (#34238302)
Palm did it ages ago with the Pre and Pixi. Worked quite well. I will say, the newer Magsafe stuff is much stronger at helping with alignment, my Belkin dock feels like it vacuums onto my phone when I connect it. I recall the Pre and Pixi often requiring a bit more manual intervention.

If magnets are used to give the correct orientation, why not also have POGO pins or indentations next to the coil?

Case 1) the device only supports wireless charging (say because it's waterproof): business as usual

Case 2) the device also has conductive metal dots: the POGO pins can then charge the device much faster.

Re:Next-generation Qi2 wireless charging standard embraces A... by vlovich123 on Tuesday January 03, 2023 @04:29PM (#34238347)
POGO pins wouldn’t really impact waterproofing unless I’m missing something (similar to how you can have a USBC / lightning port on a waterproof phone).

Is super the real reason is this would have limited value because:

A) you have this already through cable charging

B) it’s not clear it would meaningfully change the charging speed since you’d also need a communication standard (eg USB-PD) to negotiate the charge rate

C) all of this is made moot by the fact that most people have a case on and don’t take their phone out of their case to put it on a Qi charger which negates the benefit.

So basically cost and complexity for limited to no value. Of course maybe C is solvable by extending the pin through the case but I would think it would add cost to the case + maybe create some structural challenges negating the shock absorption.

Honestly I am not sure why more devices don’t bother with pogo pins. It can provide close to the benefits of both wireless convenience, and wired efficiency together. My iPad and Amazfit watch are the only things I have that have pogo pins.

(And yes they can get dirty etc but are also easy to clean. Not like USB ports don’t gunk up, or Qi doesn’t have issues either. Plus it’s very likely cheaper!)

Re:Next-generation Qi2 wireless charging standard embraces A... by bonney_io on Tuesday January 03, 2023 @04:06PM (#34238061)
I love Qi, and I really love MagSafe, so I'm happy that magnetically-aligned-Qi is becoming the standard.

Although, sadly, I suspect that Apple will continue to incorporate their own NFC identification into their Qi2 devices, and that alone will be what differentiates "MagSafe" from Qi2 -- almost certainly including limiting faster wireless charging to MagSafe.

Re:Next-generation Qi2 wireless charging standard embraces A... by newaccount74 on Tuesday January 03, 2023 @04:10PM (#34238112)
I tried to jump on the Qi bandwagon and got a bunch of Qi chargers, and various devices (iPhone, Airpods, Mouse)

Unfortunately, the experience just sucks. Charging is slow, if you misalign it it doesn't charge (some devices have the coil off-center!), devices get hot while charging, chargers that work well for phones don't work for other devices...

I'm disappointed and I've mostly gone back to charging with cables.

I haven't tried any Magsafe stuff yet, but since it only works with iPhones it's a non-starter. I don't want a charger that charges just a single device.

If Qi2 gets adopted it may be worth a try, but I think ultimately wireless charging is a gimmick that may be useful in special scenarios (eg. car mount), but for the most part I don't think it's a replacement for cables.

Re:Next-generation Qi2 wireless charging standard embraces A... by JamesSwift on Tuesday January 03, 2023 @04:38PM (#34238452)
I got a pretty cheap anker QI charger that is "phone shaped" and havent had any issues. It looks something like this [1]. You can easily align by feel even in the dark. It also has a circle where the coils are which makes it really easy align my airpods as well. Very happy overall.

This is solved by MagSafe, the magnets are so strong that it snaps to the device. My wife always charges her phone with Apple's MagSafe charger. I also have one, but since I only charge overnight, plugging in a cable is not much effort.

If Qi2 would become more popular, perhaps cafes, restaurants, etc. could have wireless charging spots.

Re:Next-generation Qi2 wireless charging standard embraces A... by 8ytecoder on Tuesday January 03, 2023 @04:20PM (#34238238)
I have a belkin 3-in-1 charger. The phone basically attaches via the magnet and “floats”, so it has to align properly. Same with the Apple MagSafe charger that can also fast charge. It snaps in place. Both are great for lazy absentminded people like me.

wouldn't that mean if you take your phone, the charger still sticks to it?

when I was using qi, I'd have it on my desk, and of course I regularly pick up my phone with one hand to do something with it or take it with me, can't un-stick a charger at the same time with one hand...

Re:Next-generation Qi2 wireless charging standard embraces A... by mattmaroon on Tuesday January 03, 2023 @05:48PM (#34239263)
You can unstick it with one hand easily because you’re normally using something like a vertical stand or a mat that’s heavy enough. You just have to lift the phone from the bottom or top rather than the middle.
Re:Next-generation Qi2 wireless charging standard embraces A... by JonathonW on Tuesday January 03, 2023 @05:53PM (#34239301)
It doesn't stick strongly enough that you can't push it off with your fingers-- easier to do that one-handed than unplugging a Lightning or USB-C cable.

With a heavier Magsafe charger (like most of the stands out there), you can just lift the phone off and the charger won't come with it. MagSafe's just strong enough to hold a phone on a stand or hold a charger puck to the phone, but not much more.

Re:Next-generation Qi2 wireless charging standard embraces A... by msisk6 on Tuesday January 03, 2023 @05:53PM (#34239306)
I pick up my iPhone on a MagSafe charger with one hand all the time. As I pick it up I just use a finger to slide the MagSafe puck sideways and it releases. Not a big deal at all.

From what I've heard from starbucks employees who were there during the wireless charger tests: theft, device incompatibility, and people didn't know how it worked creating increased stress on baristas.

Once there is a universal standard every phone uses, it works 100% of the time (magsafe does help here), and is able to be completely flat (or incorporated into tables/desks), then you'll see an uptick in wireless chargers at cafes/restaurants.

I think hotels have been adopting them faster.

Re:Next-generation Qi2 wireless charging standard embraces A... by Kuinox on Friday January 06, 2023 @08:58AM (#34274582)
I don't understand why you are trying to create a standard when there is already one. My android phone can wirelessly share battery to an IPhone, my external battery can also charge wirelessly androids or iphones.

heck, even induction cooktop can charge phones.

Did you looked it up on amazon ? There are tons of flat charger.

Re:Next-generation Qi2 wireless charging standard embraces A... by tannhaeuser on Tuesday January 03, 2023 @04:35PM (#34238419)
An iPhone snaps in to the strong magnets in Apple's wireless charging pad, and I can say it works flawlessly and almost as fast as charging over USB-C. Using it all the time, also helps with wear on USB plugs.

The problem with wireless chargers is you have to keep a thing sitting around vs a cable you can shove off to the side. I too bought a bunch but lost interest in using them as they were in the way.
Re:Next-generation Qi2 wireless charging standard embraces A... by Bluestrike2 on Tuesday January 03, 2023 @04:51PM (#34238606)
Personally, I have the opposite problem: whenever I push a cable off to the side, it'll inevitably fall down behind the desk/cabinet/side table/whatever. Clips can help, but it can still be a minor nuisance.

That said, your complaint isn't uncommon. I build furniture on the side, and have built a couple desks and night stands with built-in wireless chargers for people who wanted everything hidden and out of the way. The charger gets mounted from the underside so that nothing is visible, and I inlay a marker--something like a ring or bowtie inlay--on the surface so you know where to align your phone.

I've also seen chargers on the market that can be mounted into a hole you drill or are sized to fit standard wire grommet holes common on most desks for sale. That's way less fun (IMO), but anyone can install them with a few minutes and a hole saw (or an existing grommet hole, if it fits). No clue if you can find Magsafe ones, but I'd assume so.

Re:Next-generation Qi2 wireless charging standard embraces A... by WWLink on Tuesday January 03, 2023 @06:44PM (#34239787)
I have a nice charging pad on my desk under my monitor. I have a few phones that I use right now (one for work, one personal, one is a gadget), and it's really nice to just plop them on there when they're at like 50%.

The slow charging is fine by me. Fast charging wears the battery out faster.

With this, I don't have to worry about lightning vs usb-c or whatever. I don't have to worry about my work phone trying to share data with my computer. I don't have to worry about annoying programs trying to sync with my personal phones lol.

Re:Next-generation Qi2 wireless charging standard embraces A... by hedgehog on Tuesday January 03, 2023 @05:19PM (#34238950)
I use Qi most of the time at my desks, cheap chargers from Anker and Ikea. Alignment by touch is second nature and easy with one hand (vs two to plug in a cable). It probably depends what your usage pattern is but I find it very convenient. I use a cable in my car because it's more reliable and less ambiguous whose phone should connect to the dash display.
Re:Next-generation Qi2 wireless charging standard embraces A... by yborg on Tuesday January 03, 2023 @11:10PM (#34241921)

Apple contributing to an open standard here must mean they've got ambitions to go portless with the iphones.

With wireless-only charging, prevalence and compatibility is more important than exclusivity and using it as an USP which they usually seem to prefer.

Re:Next-generation Qi2 wireless charging standard embraces A... by dagmx on Tuesday January 03, 2023 @04:26PM (#34238300)
Idk if that is a good extrapolation necessarily, they also contribute to USB-C.

More likely, it’s better to just have their standard be the main one so they don’t need to deal with the complexity of messaging “well this doesn’t work on our phones etc”

Re:Next-generation Qi2 wireless charging standard embraces A... by arsome on Tuesday January 03, 2023 @05:31PM (#34239080)
Wireless only charging would be wasteful as it's rather inefficient (most tests show about 50% more energy put in to achieve the same charge) and this magnetic system is unlikely to work well for anyone who uses a case to achieve good coil alignment... I really hope the market doesn't go in this direction.
Re:Next-generation Qi2 wireless charging standard embraces A... by threeseed on Tuesday January 03, 2023 @06:18PM (#34239547)
a) Wireless charging is a significantly better user experience. Every morning I quickly put my phone up against a magnetic dock, there is a click and it charges. I can also attach battery packs the same way. No cables. No hassles.

b) MagSafe cases exist which are also magnetic and so there is no issue with coil alignment.

Well, I'm frankly surprised you can patent it at all, but you can cover many possible implementations in a single patent.

That's pretty much worthless as far as magnetic alignment. That patent is specifically geared towards foreign object detection.

Re:Next-generation Qi2 wireless charging standard embraces A... by brookst on Wednesday January 04, 2023 @10:07AM (#34246339)
Point being, there are probably tens, if not hundreds, of patents for magnetic alignment of wireless chargers. You asserted there is one and only one all over this thread, and that’s not how patents work. Only the specific implementation, to some level of detail, is covered.

Apple had about 40 patents in this space, Samsung has a bunch, etc.

This is potentially fantastic news, if only to have a universal magnetic mounting standard across mobile devices. The past few years have seen an explosion of cool applications of magsafe:

- Corridor Digital made a multi-phone mounting rig for recording multi-focal-length slow-mo. Lots of interesting maker possibilities. https://www.youtube.com/watch?v=v8X16Gw3Qa4

- Peak Design has a line of mounts which combine magsafe and a physical locking mechanism for sports https://www.peakdesign.com/collections/mobile

- Continuity Camera mounts (for using your phone as a webcam) is a hacky but brilliant example of where a temporary magnetic mount is extremely useful

As an Android user, this ecosystem was opened up by a Peak Design case (which is compatible), but I hope to someday have a phone with built-in magnets, too. But it's not useful unless the magnets are compatible everywhere!

Science fiction writers have envisioned this for decades. I look forward to the future of finally being able to stick my phone to more things!

Re:Next-generation Qi2 wireless charging standard embraces A... by bergie on Tuesday January 03, 2023 @04:29PM (#34238346)
Earlier Google devices had magnets for Qi charging alignment. I think in the Nexus 4/Nexus 7 era. I had a Google Qi charger with strong enough magnets to hang the device on the wall.

And then in typical Google fashion, the concept was dropped in a year or two. Happy that Apple (and now the Qi consortium) picked it up.

The one thing that’s been bugging me, and this updated standard fails to address, is that many devices that would benefit from wireless charging are too small for Qi and MagSafe (ex. bicycle lights, toothbrushes and grooming products, etc.)

A mini-Qi based on the Apple Watch charger, or a smaller ring of magnets inside with a compatible charging coil, would have been really outstanding… I feel like this standard is just another thing that will have to be revised in 3-5 years.

Oh this is exciting!

What I really hope to see is a lapdock using this tech. I have a few lapdocks (basically laptop-shaped docks for your phone) and the most annoying thing about them is dealing with the short USB-C cable you need to plug your phone in. This would open the door to wireless charging from an arm that extends from the side; if you combine that with a wireless display standard (Miracast is the main non-Apple one these days though it's not well-supported) you could have a completely wireless lapdock that still charges your phone while you use it.

Just plug a cable in! You get Ethernet and real high-bandwidth video and high-current charging and audio and PCIe (Thunderbolt) and and and.

A number of years ago I worked with a colleague who had been one of the original electrical engineers at Splashpower [0] in the early 2000s. Splashpower was a Cambridge UK startup developing wireless inductive charging. Their aim was to create something similar to the multi device charging pad that Apple intended to launch but cancelled (the Splash Pad!), Apples was rumoured to be in development when I worked with them. He didn't think they would be able to achieve it (I think I remember him predicting high power draw and lots of heat, what is rumoured to have been the problem)

From memory (this is about 8 years ago) Splashpower found that miss alignment of the coils massively impacted the performance and as a result struggled to make the multiple devices charger pad work. The magnetic alignment of Apples MagSafe system, or the chargers on the old Palm phones, should aid in making them significantly more efficient.

Ultimately Splashpower went bust, the IP was brought by Fulton Innovation who, combing it with their own IP, then went on to create the Wireless Power Consortium [1] and the Qi charging standard.

It's interesting how it's going full circle and Qi2 is now incorporating magnetic alignment.

Or, if you're an induction cooktop manufacturer, a feature.

I'm highly amused that we've gone from large / heavy coil based transformer AC adaptors, affectionately known as wall-warts, to highly efficient tiny switch-mode electronics, just to jam a poorly wound and poorly aligned coil pair back in the circuit.

My phone has 15 watt Qi charging, how novel.

I'll stick to cables.

Re:Next-generation Qi2 wireless charging standard embraces A... by KRAKRISMOTT on Tuesday January 03, 2023 @06:00PM (#34239372)
I don't understand why Apple won't make a charging mat that charge directly through the electrical contacts on MagSafe instead of relying on the induction method.
Re:Next-generation Qi2 wireless charging standard embraces A... by crooked-v on Tuesday January 03, 2023 @06:25PM (#34239611)
My guess would be that driving that much power through direct connectors would clash with their goal to make everything phone-related increasingly waterproof.

With the purely induction-based method, you can, say, have connectors poolside (assuming you've got long and suitably grounded cables) with no concern from errant splashes.

Re:Next-generation Qi2 wireless charging standard embraces A... by vineyardmike on Tuesday January 03, 2023 @06:52PM (#34239853)
The phones are already waterproof with electrodes on the outside of the device. Charging ports are still the outside from a poolside perspective.

Magnetic Qu charging is already a standard, they can build off it. It supports plenty of existing chargers. They released it before MagSafe. MagSafe just makes it more efficient in a way that doesn’t require more power.

Re:Next-generation Qi2 wireless charging standard embraces A... by fomine3 on Tuesday January 03, 2023 @07:53PM (#34240382)
Waterproof charge electrodes are thing for a long time. I think Apple loves glass on phone back so they can't adopt it.

I work in metal fabrication, rarely took my last MacBook to work, but the micro fine metal follows me home and ultimately resulted in destruction of that laptop due to the magnets in the charge connector.

Apple's phones are too fragile for my liking too, after having ruined a few in this environment.

I liked using Apple's gear, but it's all too precious-jewelry like for me in this industry.

If Apple did a rugged phone with a 13500 mAh battery like my current daily driver I'd switch right back.

What phone do you use that is immune to metal filing dust?

Seems like anything with a speaker would succumb, and its more of a problem with the case you chose than the device.

I couldn't agree more, but my main use-case for wireless charging is my desktop cradle. I keep my phone sitting in it during the day and it maintains 100% charge until I leave for the day.

I wouldn't try to do a deep charge from like 50% of something wirelessly... I've got better things to do!

Re:Next-generation Qi2 wireless charging standard embraces A... by skybrian on Tuesday January 03, 2023 @07:14PM (#34240033)
Keeping the battery fully charged when you don't need to likely wears it out faster. 50% charged would be ideal for longevity, it seems.

Presumably an android phone (without magsafe)? My bedside charger is magsafe - it works very well and is one of those small things that works well and improves the experience.

There's a lot of stuff in the apple experience like this, that android users seem to scoff at - and then they try it and get hooked. I'm really glad Google is building their own phones and trying to push them as first class devices - iOS and iPhones desperately need strong competition.

Re:Next-generation Qi2 wireless charging standard embraces A... by kaladin-jasnah on Tuesday January 03, 2023 @06:24PM (#34239596)
The problem is when you're and Android user like me—my only criterion is that the phone can have its bootloader unlocked and has good custom ROM support. This prevents e-waste in the long run (past custom ROM or official OS support) since I'd be able to always find some use for the phone—be it desktop Linux or whatever (for phones like the OnePlus 6, this is why the device is so incredibly compelling to me).

Unfortunately iOS devices are totally uncompetitive in this important space.

Re:Next-generation Qi2 wireless charging standard embraces A... by parker_mountain on Tuesday January 03, 2023 @06:38PM (#34239745)
iOS devices generally receive os support for 5 years past their last retail shelf date (longer than when you bought the phone!). There's a lot to criticize apple w/r/t locked down devices, but their support lifespan is pretty good!

Compared to most smartphones, it's pretty good, but compared to PCs it's pretty bad.

Overall, it's a sad state of affairs imo. Why do phones become obsolete so quickly when other computers can be perfectly usable for well over 10 years?

I'll answer as if this is a real question: the overall rate and pervasiveness of change for that class of device.

Re:Next-generation Qi2 wireless charging standard embraces A... by jsight on Thursday January 05, 2023 @09:38AM (#34260113)
It makes sense. The Snapdragon 800 and 801 weren't particularly slow. While cameras have certainly improved, even those weren't bad back then.

I suspect that 2022/2023 flagships would hold up really well 10 years from now.

Re:Next-generation Qi2 wireless charging standard embraces A... by kaba0 on Wednesday January 04, 2023 @09:03AM (#34245584)
I mean, you are talking about a general purpose computer + quite great camera + multimedia device that fits in your pocket and is battery powered. The only ones we get close to 10 years of review were pretty much experimental phones, only recently did we reach a much more slower pace of development where a current gen phone is not that different from a 3 years older gen one. Current ones use much more durable materials (steel frames, glass which is contrary to “breaking easily” is one of the hardest materials, thus being very scratch resistant), and better, more performant hardware that won’t become multiple times better year-on-again, so besides replacing the battery every 3-5 years, they might very well have a longer lifespan.
Re:Next-generation Qi2 wireless charging standard embraces A... by kaladin-jasnah on Tuesday January 03, 2023 @11:57PM (#34242199)
After that support cycle ends, the phone will rapidly become less and less useful. I could've bought a OnePlus One 8 years ago and still have Android 11 or 12 from custom ROM support, or some Linux distribution.
Re:Next-generation Qi2 wireless charging standard embraces A... by parker_mountain on Wednesday January 04, 2023 @01:07AM (#34242567)
You could've, but have you held on to a phone that long? I suspect very few people have made the bridge from "could" to "have".

Between the

- battery lifespan (a technology that has tradeoffs between lifespan and capacity, such that manufacturers target 3 year lifecycles

- driver updates and baseband security (famously out of date on older android phones, no matter what "rom" you're running)

- ports lifecycles (the charger port has a finite lifecycle of plug cycles, also often cheaped out on a bit)

- lifespan of custom ROMs (frequently losing contributors and thus updates)

Is that phone really going to last 8 years of daily active use?

I think the answer is no. Apple has made a huge effort with the iphone 14 (not pro), to re-engineer the device to make it easier to repair and recycle. We'll see if that pays off, but I don't think holding on to a phone for 8 years is feasible or practical for enough people.

Re:Next-generation Qi2 wireless charging standard embraces A... by alwayslikethis on Tuesday January 03, 2023 @06:27PM (#34239639)
Yeah. It's rather ironic that Google's phones have the best support for de-googling and comes close to it being a first-class experience. Samsung and Huawei iirc are the worse ones, which tries what it can to stop you from unlocking and cripple the phone if you do.
Re:Next-generation Qi2 wireless charging standard embraces A... by kaladin-jasnah on Tuesday January 03, 2023 @11:59PM (#34242210)
American Samsung phones don't even let you unlock the bootloader. My friends have had to import Exynos-based Samsung phones to the US to truly own the hardware we bought.
Re:Next-generation Qi2 wireless charging standard embraces A... by astrange on Tuesday January 03, 2023 @08:22PM (#34240646)
You’d just find the hardware isn’t capable of what you want it to do, because it wasn’t designed to do that, it was designed to be a phone.

Or in other words, it’s all fun and games until the flash dies because you used up the lifetime writes.

Re:Next-generation Qi2 wireless charging standard embraces A... by kaba0 on Wednesday January 04, 2023 @08:58AM (#34245534)
Are you serious? Iphone devices easily live for 8+ years as is, android is unfortunately the platform where your perfectly fine phone can easily be “canceled” 1-2 years down the line on purely software grounds, even Samsung promises only 3, recently 4 years of support!

Oh, and don’t forget the reality of those “open” bootloaders, besides pixels almost all of them come with the huge caveat of wiping proprietary firmware ASAP, bringing your fancy camera’s quality to the dirt for example. So, do your phones really get a new life?

Re:Next-generation Qi2 wireless charging standard embraces A... by kaladin-jasnah on Wednesday January 04, 2023 @09:26AM (#34245823)
I am serious! Like I mentioned, I only care about the phone having an unlocked bootloader so I can install whatever software I desire, which means I don't really care about the camera or any of its features. I like to live a simple life. I have a nice Canon mirrorless camera for when I need good quality photography. As long as the phone can make calls, browse the web, send text messages and have a few messaging apps on a custom ROM (which most support), I'm plenty happy.

Re:Next-generation Qi2 wireless charging standard embraces A... by parker_mountain on Tuesday January 03, 2023 @06:39PM (#34239752)
I didn't say it was a problem :) I said it's an improvement in the experience - and small, as I mentioned. Just one of the many small things i notice with iphones that make it hard to go back to android - and I have a pixel 6a for a work phone, so I'm aware of what the user story is like on that.

It's a small thing, but basically what I have is a magsafe stand next to my bed. I can lean over, with one hand, and rest the phone on the dock, and it latches into place. When I want the phone, I can gently tug on it - with one hand.

I have one on my desk as well. Place the phone down - never have to worry about aligning it with the qi pad, pick it up and it's been charging for however long i've been sitting.

I still don't get the hype. Like sure, its less effort, but the effort being discussed is such a trivial amount. It takes me as much effort to plug in my phone as it does to scratch my back or something. I don't even think about it. There's so many things I plug in over the course of modern life.

Re:Next-generation Qi2 wireless charging standard embraces A... by threeseed on Tuesday January 03, 2023 @06:39PM (#34239755)
I move from home desk/bed, car, work and can charge my phone in a second.

As opposed to having to remember to bring a cable, reaching into my bag each time to get it, plugging it in on both ends etc.

That's closer to a minute each time.

Try groggily inserting your cable into your phone at 2AM in the morning as you remember you need to charge it. Or you could just snap it to a magnetic charging surface and be done with it. MagSafe to lightning is what USB-C is to Micro USB: not necessary, but nicer.

Re:Next-generation Qi2 wireless charging standard embraces A... by TexanFeller on Tuesday January 03, 2023 @10:41PM (#34241733)
I actually find it difficult sometimes to drag my iPhone 14 over my magsafe charger so it actually snaps to it in the dark. Easier for me to feel for the cable and lightning hole. Also you can use the phone while charging from a cable, but not very well while magsafe charging. Magsafe is fantastic for the car though.
Re:Next-generation Qi2 wireless charging standard embraces A... by seanmcdirmid on Wednesday January 04, 2023 @01:03AM (#34242540)

News to me about the lightning sockets. I've been using them since the iphone 5 and just about every part of the phone other than the socket seems to break first. I solved cable fray by buying non apple lightning cables.

A tradeoff is that my cat walking on my nightstand can stop the phone from charging, but MagSafe would take care of that.

Re:Next-generation Qi2 wireless charging standard embraces A... by wlesieutre on Wednesday January 04, 2023 @03:44PM (#34251256)
Haven’t had insulation problems, it’s more that the pins on the lightning connector eventually wear and stop connecting consistently. For MFi cables I believe that part is supplied by Apple and will be the same across all brands. Most of mine have been Anker.

I’ve also had USB-C charging cables fail, and the springy charging pins on my Pebble weren’t great either. Lightning or USB ports on phones will also get gummed up with pocket lint. Not making a physical connection for charging just seems to work better long term.

Re:Next-generation Qi2 wireless charging standard embraces A... by asdff on Wednesday January 04, 2023 @03:53PM (#34251396)
Thats assuming the magsafe chargers also don't have their own issues crop up over time. The pin issue must be rare because I've never experienced it, or maybe I have enough chargers where my usage is distributed enough to never use them to that point. Plus it doesn't justify not having a port for other things that need a hardwired connection, like audio out. Bluetooth is not a replacement for 3.5mm.
Re:Next-generation Qi2 wireless charging standard embraces A... by 0x457 on Tuesday January 03, 2023 @09:16PM (#34241102)
On the nightstand, I have Pixel upright charger, it turns my phone into a clock (turns off-screen if it's dark). I can grab it and put back on effortlessly without looking for cable, plugging/unplugging, cleaning lint out of usb-c port.

On my office desk, I have another wireless charger, but this one is flat. Place my phone/headphone-case on it, and it's charging. If I need either - just pick it up and go. I don't have to think about plugging the cable and accidentally pulling it when I forget to unplug it.

That makes me charge my phone more often during the day (i.e. charge at 50% to 80%). During the night, it doesn't matter because the phone is slow charging to be at 100% around the time I wake rather than charge to a 100% and then sit at it the entire night.

If I do need a quick charge - I just unplug the wireless charger and charge it. Airport lounges have charging spots on tables - don't have to: a) trust their USB ports b) get cables and charger out of my bad. Cars have them.

Anyways, not going back to charging with wire anytime soon.

At least MagSafe is better for the environment (minus the magnetic e-waste), as regular wireless charging is highly inefficient from a wall-power to phone efficiency standpoint.
