So for any of you out there using a Samsung Galaxy S3 with wireless charging accessories, I have some questions for you. I'm trying to decide on my next phone, which will be either a used Galaxy Note II or a used Samsung Galaxy S3 (Sprint variants both). Each has its pros and cons, and I'm divided between them. One big difference I noticed is that the Sprint Note II variant has the wireless charging pins omitted, making wireless charging impossible. The Sprint S3 has them included. I'm trying to decide if wireless charging is a nice enough feature to sway me one way or the other. Here are my questions:
Is charging the S3 noticably slower when using wireless charging?
Does it consume a lot more power when charging wirelessly vs wired?
Are the wireless charging pads out there pretty particular about orientation of placement, or is it pretty easy to just toss them on the pad and get a good charge?
In short, I'm just trying to find out if this feature is mostly hype, or if people are really liking it a lot.
1) it's faster than usb but slower than AC. (you can also modify it if you have a kernel that allows you to adjust the charging rate, but do this at your own risk)
2) not really that much more. I highly doubt you'll ever even notice a difference in your electricity bill. If you really want to be exact, then you might want to use a kill-a-watt and measure the difference from a certain range (say 50% to 100% on AC vs wireless)
3) they are slightly picky. it depends on whether or not you'll be using a thick case to go with it. In some cases, the bigger cases like the otterbox armor will not work, but cases like the ballistic Sg would work just fine but requires you to be slightly more accurate than using it without a case)
wireless charging is a convenience. I personally like it a lot because I don't have to plug it in all the time and it allows me to just place it and let it charge especially when i'm working at the office with little to no reception. it'll keep my phone topped off at all times even when my phone is constantly hunting for signals.

Saw this article this morning. Thought I'd share it.
http://www.phonearena.com/news/Samsung-Galaxy-S-III-wireless-charging-kit-introduced-by-Zens_id32935
Won't be coming out until September, for about 85 USD, but at least there will be options.
Does anyone know how much the official one will cost?

anyone know how wireless charging compares to outlet powered charging as far as strength and charge time?
$85 to me just seems ridiculous for a wireless charger when the technology obviously doesn't cost nearly that much. I think even after these official setups come out that I will stick with the palm touchstone conversion if I decide I want to do wireless charging. Even if I mess something up I can buy and screw up 8 of those before I even get close to paying $85.

I agree, the touchstone cost less, but with the touchstone charging rate is only 500mAh which has slow charging time.
I'll like to see the official one first.
The Qi standard offers a maximum of 1A in low power mode but a lot of the ICs on the market (TI) only support up to 500 mA. 500mA is about half of dedicated wall charging one I believe and the same as when you plug it into your PC to charge.

I plan on modding a case to do this. I am currently looking for some schematics because I have a feeling that this was provisioned in the design of the phone.

1A is more like it,the SGS3 has a charging rate of 1A through the mains.
i'm not in a rush for one so i'll see bother before I decide.

I'm not too sure myself, but I've heard some people say it takes longer and others that say it takes just as long. I know when my husband had the palm pre and would use his touchstone it really didn't seem to be a very noticeable difference in time.

Does seem a little pricey, but would love to pick up one for my desk at work, grab and go when I go out on the floor.
It's new technology(For phones at least) so obviously they gonna rip off the early adopters, I mean I bought one for Nintendo DSI for £3 which has identical technology to what they put in that so I'm gonna take that apart and if it works just buy a cheap battery cover and stick it together.
If it is qi or compatible then the energizer charging pad will work. It is well worth the money imo. I used it with tbolt every night , before my slim, lean, toned s3 arrived. Now I just can't decide whether to ripe one of my spare tbolt qi doors apart or wait for factory s3 qi door.
For what I've seen if the palm is so easy why not use the "proper" dock and hack a tbolt or similar door.

Hopefully this combined with the Verizon version that someone posted some photos of will put some pressure on samsung to hurry up and release the official one...
Sonof the zens unit is $85 then the official Samsung one will be $100or more.
still no word on the wireless kit?

For overnight charging, this is a good thing - extends the life of your battery. The higher your charge rate, the less your battery will ultimately live. The performance of your battery overall will degrade. Slow charging is a good thing.
If you want a fast charge, just plug into a USB cable if you are in a pinch.
Also, I read in the Galaxy Nexus threads (where the Palm Touchstone mod originated) that there's a software mod they are applying to increase that rate up to be nearly as quick as the 1A charger. The same type of mod may be applicable here.
I just got my ZENS+Shield kit for the S3 that has the protective shield instead of the OEM-style backing. I'm loving it!
Previously I had been using an OEM back with a Touchstone wireless charger installed in it, but I really wanted to have my elago slim hard case that makes the buttons recessed. I made an ugly hack that made it work most of the time but I hated having to fiddle with those Palm Touchstone chargers and making it align to the magnet.
Sometimes my cat could get annoying and just nudge it or maybe the phone would vibrate enough from alerts, it would get into this "charge-discharge" loop state that can't be good for the phone, sometimes even fully lose contact. It was just not very reliable -- I found myself sometimes just plugging it into USB to get a better charge.
The ZENS wireless back fits really well and provides the backing I wanted. I wish the texture was a bit more grippy but it's not exactly slippery. It's on-par with the stock grip. It's a bit heavier and slightly more bulky than the elago case but that's because it provides a bit more protection and has a rubbery pad for some sort of shock protection.
The charger is great too. I can put the phone in just about any position and it'll charge. They even brag it'll charge if you put it on a high volume speaker in the instructions (but it may take up to 2 mins for it to "negotiate" in that case.) It seems to charge faster than my Touchstone.
It's Qi standard so I should be able to use it with any charging pad. I was shopping for a second charger but the 3-position Energizer looks much too big as does the Duracell and the single position Energizer is slanted and I've read some people have issues with it sliding off. I like that the ZENS charger is flat and the size is nice, so I ordered another.
There's one downside to the ZENS charger but I think other chargers (except the Palm Touchstone) suffer the same problem: they do not use USB as a power source. My ZENS charger uses some ugly wall-wart. Also it's a bit more expensive.
Hey guys, Is there a Wireless Charger for Galaxy Tab S 8.4 or the 10.1 model? I tried searching but I keep seeing Qi Wireless Charger supporting most of other android device except Galaxy Tab S. Please do let me know ( link) if you found a wireless charger for your Galaxy Tab S. :fingers-crossed:

The Galaxy tab does not support Qi charging built in. To only way to support wireless charging would be to add a universal micro USB Qi receiver such as the one in the link below. However based on the size of the tablet, not sure if this would even work well due to the position of where the receiver would sit in comparison to the charger. Personally, don't think it's worth it on this tablet.

There is a reason, which is to reduce the wear and the chance of breaking the usb port. 2 different phones I was able to keep using for a year after the usb port broke because I had hacked in the receiver from the Palm Pre. There was no way (for me, without more exotic equipment than a fine tip soldering pen) to re-solder the usb port. Too much stuff crowded around it and it was surface mount. But I could get 2 wires on to the ground and +5v easy.
Warranty isn't an option unless you never rooted, so that leaves having to be very careful never to break this weak point for the next 5 years.
Myself, I can't see sticking that thing on mine either, I'm just saying that there are reasons one might want to and it's not automatically ridiculous or pointless.

Don't get me wrong, I love wireless charging and have been using it for a couple of years now on my phones. I also thought about it for my LG G Pad 8.3 tablet. However don't think its a good option for the 10.5. Reason is as I mentioned, positioning. Most chargers are small. Positioning the tab on it may prove to be challenging due to sign. I think it would end up leaning off to one side and not being able to get in a good position. Thus would be frustrating. I think the 8.4 would stand a better chance but not the 10.5. Just my opinion anyway.

You could probably just put the charger on the tablet in that case. It's also perfectly possible to make your own tray that has the charger embedded in it.
For devices too large for the charger. Cut a piece of cork(same thickness of the charger) to the size of the largest device that needs charging. Cut out a hole to imbed the charger into the cork. Cut out a hole in the end of the cork for the charger power cord. The end result is the charger and the cork will provide a nice flush surface to charge any size tablet.
An easier way to charge tablets is to lay the tablet face down and set the charger upside down on the bottom of the tablet.
QI is designed for phone
Guys,
Ive been charging my tab (had a couple.. current one is Samsung Tab A) for years.
I simply buy a charging receiver with a USB connection. Plug it in, tape it onto the back and away you go...BUT...
USB charging receivers are designed for phones. 2000, 3000mah batteries so a charging input of 1000mah is ok. The tab battery is 6000 so a 1000 charger is Slooow
Most USB (wall) chargers are 1000mah and/or 2500mah.
wish someone would make a 2500 qi qharging receiver.... then life would be much better.
Even thought of updating my tab so I have faster CPU and USb type C connection... problem is QI for USB-C is also only 1000mah... WHY???
Faster charging would be much better

Is this a thing that can be done? Without having a back stick to the outside of the phone.. Like ate they different cases for us that want to use it?
You'd have to have a case with it built in. Wireless charging won't work through metal.
I have wireless charging currently on my Nexus 4. Although it is a nice feature I'm not so sure I will miss it on my pre-ordered HTC One M9.
When charging the Nexus 4 becomes quite warm and in summertime downright hot. For me a cable is just as good.
Got this to use with my Note 5 but have had success using it with the Nexus 7 as well. I have a video here
https://goo.gl/SHlM2Z
I have multiple wireless chargers. $3 cheapies, Samsung OEM, Spigen 3 coil wireless, and now this. This is by far the best one out of all of them. Just the fact that it has worked fast charging is great because you don't lose the charging speed that typically comes with wireless charging.
I tried this with a Note 5, S6, and a nexus 7. Worked well on all those devices with zero issues. The charger is heavier and feels sturdier than the other ones I have. I'm guessing whatever is inside to enable fast charging must be a pretty dense set of components.
Not sure if it's 3 coil but connects without issues every time. So far I haven't had an issue of having to mind it around to get it to connect. Tried with and without cases and haven't noticed a drop in charging time.
Definitely picking up a second one to leave at my office.
Hi,
does it mean that the fast charge is available with the Nexus 7 ?

Looks real nice
Hi team,
If you saw my other thread you'll know that I've not been impressed with the wireless charging speeds the Pixel 6 Pro gets. They advertise a maximum of 12W charging with compatible Qi stands and 23W with their (new, unreleased) wireless charger.
Tl;dr: most wireless chargers won't charge the Pixel 6 Pro at anywhere close to the maximum for any sustained period of time. Even Google's own Pixel Stand (last gen) has issues pushing the full 12W predictably. In comparison, both S21 Ultra and iPhone 13 Mini could consistently pull their respective maximums and were only limited by the maximum advertised rates of the phone/charger manufacturers.
I've since done some experimenting and actual measurements. For each of these measurements, I've ruled out cable/power brick issues by
using the included cable & power brick wherever possible
reproducing the measurement with multiple, high-quality cables
reproducing the measurement with multiple, OEM or otherwise high-quality power bricks
I've also reproduced the measurements with and without cases, and at various battery levels (e.g. <50% charge, etc).
I've also compared what other phones were able to get from these respective chargers, e.g. Samsung S21 Ultra, and iPhone 13 Mini, just to confirm that they were able to pull the expected power from the same chargers. In all cases, for all chargers, the S21 Ultra and iPhone 13 Mini pulled the expected maximum charge rates given whatever the charger could push (and Apple's own restriction of 11W for non-Apple-approved chargers).
Please note, all measurements are approximate since the meters I have are pretty affordable and not high-precision, but they still give a fair idea of what is possible in the real world. Please also note that you should not generally expect peak charge rates when the battery is at 90% charge. Here are my findings for the Pixel 6 Pro's actual wireless charging experience:
Charger make/modelTypical charge rangeMaximum charge (observed)Maximum charge (advertised)Case sensitivityNotesGoogle Pixel Stand4.5W - 12W13W11WMediumThe lip is really small, so it's easy to knock the phone off of this stand, especially if you have a case. But it does seem to get the best, most consistent speeds. If you use a case, you may find it complaining about alignment randomly.Samsung 15W stand (EP-N5200)3.6W - 5.5W6.4W15WNoneFluctuates a lot; slow to ramp up. Coil does not seem to align perfectly but the phone doesn't complain.Moshi Sette Q4.5W - 12W*15W*15W on both coils simultaneously (allegedly LOL)High (hard to align with case, left coil doesn't work at all in many cases)* These measurements are from the right coil. The left coil simply did not start charging most of the time, and was especially fussy about cases. The right coil worked a lot better with and without cases. If you buy this charger you should immediately test the left coil for functionality.Samsung 9W Trio charger4.5W - 5.5W5.5W9WLow (better with case)The main coils on the Trio charger advertise 9W each simultaneous. Without a case on, the Pixel slowly slips off the charger and out of alignment.
I think the numbers speak for themselves, but you can imagine I'm pretty disappointed in these results. I'd love to find out if anyone's getting a better, more consistent experience with wireless charging on their Pixel 6 Pro, and if so, what charger/case they are using. In short, in terms of wireless charging compatibility and experience, the Pixel 6 Pro is a big step backwards compared to the S21 Ultra.
I have the Samsung Trio and Duo chargers, they are awesome for my old S20 and Watch. But yeah it blows for the Pixel 6 Pro. I also have Pixel Stands, it seems like it doesn't charge as fast as Samsung phones though.
Over the last two weeks I've gone down a rabbit hole trying out different Qi chargers and am also very disappointed in what I have seen so far. I've specifically tried to go for ones that say they can do 15w Extended Profile on the wirelesspowerconsortium website. So far I've tried:
Pixel Stand
Spigen Arcfield 15W
Insignia 15w Pad
Mophie Snap+ (magnetic magsafe like one)
ForCharge Slim Wireless Charger 15w
In each case I've used the same Ravpower 61w GaN brick as the source and while they all initially seem to charge pretty fast at roughly the expected 10-11w, they ALL drop to half that (or below) after a relatively short period of charging.
I've tried this with both the Moment case (which has faux magsafe) as well as naked but the results are pretty similar. The charging is great for maybe 10 minutes then just becomes horrible, it can barely keep up when im driving and its on the mophie snap+ charger.
Thanks for sharing your experiences. On the one hand I'm glad I'm not alone in having this issue but it's disheartening to hear that the charging on this phone (wired AND wireless) is such a PITA. On wonders wtf is the real problem? Like, why does this specific phone have so many issues? Is it the custom silicon (Tensor) that just doesn't offer the same level of capabilities as the last Snapdragon? I'm worried that issues like this help explain why Google didn't release the new Pixel Stand at the same time as the phone.
I mean, can you put the phone on one of these wireless chargers and expect it to be full overnight? Generally, yes--as long as the charger agrees with the case or otherwise is grippy enough to work without a case on the phone. But if you are used to the charging speeds of the S21, or just generally maxing out Qi charging speeds which good Qi chargers, then you're in for a disappointment--at least until the new Pixel Stand comes out, whenever that might happen.
Meanwhile: my girl's iPhone 13 Mini charges at the full 15W as soon as you drop it on the Apple MagSafe charger. And it stays there consistently. Last night I charged her phone from 35% to 100% in <2 hours using that MagSafe charger.
