So be it. I think many usrs are so serious about battery consumption. For me it's ok unless it significantly drains.
[Xperia Z2 Q&A, Help & Troubleshooting] BR4DOKYBrazil:
I do not know which model of Nokia that has this feature as well and there is a warning appear when activated on that consume more battery than normal! I found it strange why Sony have not put this warning if consume more battery! Believe to be insignificant!
[Xperia Z2 Q&A, Help & Troubleshooting] easycure1974:
It did on the Lumia 1520 but they took the warning away with a touch update
[Xperia Z2 Q&A, Help & Troubleshooting] BR4DOKYBrazil:
Great !!! So it really should not be a significant consumption!
[Xperia Z2 Q&A, Help & Troubleshooting] gibbo82:
You would of thought Sony would have implemented double tap to lock as well. This feature seems pointless to me!

Although I use it to check the time
[Xperia Z2 Q&A, Help & Troubleshooting] nadimsoze:
There's an xposed module to get double tap status bar to sleep. Also you can use GEL launcher with xposed where the back button on the main home screen becomes a power button.
[Xperia Z2 Q&A, Help & Troubleshooting] saldirai:
there is no reason to implement a tap to lock feature cause there are dozens of apps that lock the screen with a shortcut :)
[Xperia Z2 Q&A, Help & Troubleshooting] langevol:
With this, only touchscreen is on, but in other app how drain the battery, the screen stay on but With blackscreen... That's why there's no battery drain in z2 ^^

My wife have a z1, and every day i have to play with it, i make a double tap and finaly realize that i'm stupid, there's no double tap fonctionality ^^
[Xperia Z2 Q&A, Help & Troubleshooting] neovalkyr:
I like this feature too but I find that my phone would turn itself on in my pocket, so I turned it off
[Xperia Z2 Q&A, Help & Troubleshooting] BR4DOKYBrazil:
The second reason why I turn off too! But I leave the screen facing the outside of the pocket!

I've been testing and I noticed that it only turn on to squeeze twice in exactly the same place, making it difficult to turn on the device in your pocket!
[Xperia Z2 Q&A, Help & Troubleshooting] BanziBaby:
Never had any issues with tap to wake affecting battery life, very occasionally it will unlock the screen when in my pocket but only when my hands are in there, great feature that saves wear & tear on the power button.

Why iphone user never worry about its power/home button?
[Xperia Z2 Q&A, Help & Troubleshooting] arash64a:
Go to iPhone Forums to see the problem of home button,

My main issue with iPhone is that ALL functions in iPhone actions with home button and this is really not good.

the second one is limited world of iOS.
[Xperia Z2 Q&A, Help & Troubleshooting] Daniel_I:
I don't belive it. I don't have this problem. Other aplication is turning your phone on, like Viber..many others, not this double tap function

For me it's working just perfect.

[G3 Accessories] Pilz:
I purchased a OEM back without any NFC or qi and a white OEM back with the NFC and qi. I'm going to remove it and make it work on the black one since I have a black G3. Both back covers will be here by Saturday so I will post pictures as I go. It may not be the cheapest or most effective way to get qi charging but it will get the job done. I just hate the ATT back with the death star on the back and I wanted to get a new one so I figured why not get qi as well.

(Pictures and walkthrough coming soon)

Let me know if anyone has suggestions or has tried this already.
[G3 Accessories] InsaneJester17:
I planned to do the same for my T-Mobile model. Hope this works out!
[G3 Accessories] bigdbag:
Where did you buy it? I just did a cursory search on Amazon with no luck. I'm looking for some way to get QI charging without having to go the AT&T powermat quicksilver case route (what the hell were they thinking going powermat).
[G3 Accessories] poczynek:
Yes I have done this. Ripped off the coil from the quick circle case and stuck unto my Korean back that didn't have wireless charging. Works great!
[G3 Accessories] Pilz:
I purchased them both off ebay. It wasn't cheap as a I said 27.99 for the black back cover w/o nfc or qi ( I just hate the carrier logo) and $40 for the NFC/Qi back cover in white. Both are USA sellers which is good.

Here are the links

Qi/NFC back (only available in white currently): http://www.ebay.com/itm/151340368484?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

Plain back cover w/o carrier logo any color:http://www.ebay.com/itm/261517044465?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2648

I'm glad, was it hard to remove? Any recommendations for when I take it apart?
[G3 Accessories] awtryau89:
I just ordered what I think is an OEM back from eBay and was planning on pulling the coil and putting in my AT&T back. How easy was it to pull? Did you have to heat it up? Any advice?
[G3 Accessories] poczynek:
I'm a bit of a bull in the China shop and have no subtlety at all and it still worked out fine as the sticker sticks quite well. I used tweezers to remove it and then removed the one from the original with tweezers. Then stuck it on and it looks ok. Let me get a photo of the finished product and I'll post later.
[G3 Accessories] Pilz:
That sounds good I'm sure there will be many people who will do this with the quick circle case.
[G3 Accessories] poczynek:
Ok here's the finished product - the trickiest part was lining up with the phone itself so the charging works.
[G3 Accessories] bigdbag:
Thanks for the link!

I just ordered the white one. I'll have to rip it off and transplant it to my black at&t cover like poczynek did -__-

I was looking at the wireless charging thread. Anyone have a confirmed working QI charger for the G3 and amazon/ebay link to it? I'm looking for something I can attach to my magnetic car mount.
[G3 Accessories] poczynek:
Get the ones that have three coils in them e.g. the Tylt Vu. They're more expensive but work well. I'd say the problematic ones are those with only one coil.
[G3 Accessories] bigdbag:
I think I'm going to try something similar to this DIY:

http://xdaforums.com/google-nexus-5/accessories/howto-make-magnetic-qi-car-charger-dock-t2531754

With a charger like this:

I'll have to do more research and make a post pending the success of this project lol.
[G3 Accessories] Protagoras:
This QI charger works, it's charging my european G3 right now. Very easy to position the phone right for it to pick up the correct spot.

http://www.amazon.co.uk/Wireless-Charger-Google-Samsung-BC252L/dp/B00FEAGZ6E
[G3 Accessories] Pilz:
No issues with the single coil? I'm looking forward to making this work, but qi chargers are hit and miss.
[G3 Accessories] Protagoras:
Nope, no issue at all. You need to position the phone at exactly the right spot, but as the charger is quite small is easy to find it. Then it charges with no interruption and tells you when it's full.
[G3 Accessories] jerflash:
I will probably be doing exactly the same thing
[G3 Accessories] monit88:
Possible to buy something like a wireless receiver for LG G3, there are tons of them for Samsung S5,Note 3 etc. That would be easier no?
[G3 Accessories] Pilz:
There are no options for that currently, so we are stick with what's available.
[G3 Accessories] Charsher47:
Would be nice if the seller didn't price gouge the sh*t out of it.

Edit: Also, how do you know it's qi charging?
[G3 Accessories] ervin10:
Did y'all pay the $140 for the oem white nfc+qi from the eBay seller.
[G3 Accessories] dimabrook:
How come i can't find any pma coils for sale on amazon. Qi coils are dime a dozen
[G3 Accessories] awtryau89:
I posted this in another thread but I though I would throw it on here too.

I was just at an AT&T store locally and picked up the Circle Case. I was going to do it just to have the PMA coils but I love the feel of this case. At first blush, I did not think I would like the folio cover and that fact may actually be true after I get some use on it. Still the back and cover are very premium feeling. It works perfectly with the PMA chargers I have and the window is very nice. The price is a bit high though. The store would not give me the 50% discount so I called into AT&T and told them my case. I ordered my G3 over the phone through Premier and they never mentioned the 50% discount on accessories on the original order so I missed my shot at the deal. Even so, they still couldn't give the 50% off. They threw a $60 credit on my bill to cover the full cost. For as much bad rap AT&T customer service gets, (which I mostly agree) that was 1st class.

One other note, I have a glass screen shield on the phone and it still fits perfectly. The folio has no issues closing or maintaining its shape.

---------- Post added at 08:23 PM ---------- Previous post was at 08:21 PM ----------

That may be the case but there are already a few members that have successfully transplanted the PMA coils. I am still thinking of trying this myself if I ultimately decide I do not like the case. Maybe we need a tutorial thread for those that have done this.
[G3 Accessories] compman25:
Did they do the pma from the circle case or the qi stuff from the international back plates?
[G3 Accessories] awtryau89:
PMA to the original back. It is a bit thicker due to the magnet for PMA charger centering so they had to alter these. I can't find the thread now and it may be in this thread but someone posted a picture.
[G3 Accessories] Forest007:
Posted this in another thread but just in case it was missed. FYI....I can confirm that the replacement back cover from Ebay seller Cellphone-Parts does work with the Verizon LG G3 and the TYLT VU Qi desktop charger. It also works with my Samsung Qi wireless charging pad mini....http://www.ebay.com/itm/151340368484?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 Same one OP posted....

Seemed like many people on here were pretty interested in this....I know I for one was...
[G3 Accessories] uabtodd:
I think that the reason this one is so heavily discounted is because it is a specific package for the iphone 4s. it comes with a wireless charging case made for the iphone 4s. since those phones are no longer being sold (I assume?), they are just trying to get rid of their stock of that particular package. you can find the exact same thing on amazon for around $16, and you can find the same thing but for other phones as well (i checked the samsung galaxy s3 package, and it was about $10 more than the iphone 4s package)

the important thing to note is that, despite this being a package for the iphone 4s, the powermat charger and portable battery charger will work with any phone, and you can just throw away the iphone 4s case =)
[G3 Accessories] dimabrook:
Hoping that's exactly the case. Last piece of the puzLe is to find some PMA coils and make sure they work without the silly cover case.
[G3 Accessories] awtryau89:
That's the one I had and it certainly did not work with AT&T. I just sent it back today for a refund. I wish I had know it would work with others phones and I would have sold it cheap to someone on here. I have a feeling its going to take forever for them to refund me.
[G3 Accessories] spdwiz18:
Just an out of the box thought: Has anyone tried looking at the com.android.future.usb.accessory.jar? I'm no DEV, but it might hold the key.
[G3 Accessories] bill875:
Thanks! I just ordered one for myself and one for my GF. I was spoiled by my Nexus 5 having Qi.
[G3 Accessories] Pilz:
I was thinking, is it possible to modify the software via xposed to trigger wirelessly charging at a different voltage to possibly enable qi. I know there is a hardware limitation, however, it was just a thought. If not is it possible to modify a qi could to make it work for power mat since they are cheaper and easier to get a hold of? I still have my qi back she figured I might as well try something with it.
[G3 Accessories] Skizzy034:
I thought AT&T had QI charging physically disabled hardware wise?
[G3 Accessories] Pilz:
They did, but I'm curious about the differences in the coils. I'll have to do some research and see if it's possible to make a qi coil into a PWA one
[G3 Accessories] sailindawg:
My understanding is that PMA charges at something like 18 volts, while Qi charges at 5 volts.

There have been some good articles on the Internet regarding this. Read here. Explains things pretty clearly.

Regarding the G3, LG did not use Qi enabled hardware at AT&T's request. The only Qi solution for the AT&T G3 is one of the USB recievers that fits under a case. If AT&T had any business sense, they'd be giving the PMA chargers away with every G3 purchase like they did with my wife's ASUS Padfone X.
[G3 Accessories] Forest007:
I'm going to purchase a black cover with no Qi coil from Ebay and put a Qi coil in it.
[G3 Accessories] dwd3885:
won't work on AT&T phone.

I Bought the Verizon Wireless Charging Folio and no go on the AT&T G3.
[G3 Accessories] awtryau89:
I just wanted to update this thread. I have started posting over in the AT&T forums but I had an interesting development today. Below is what I posted over there:

Just as an FYI, I just received my Spigen Slim Armor. I love the case but it will not allow PMA wireless charging. I have the coil in my OEM backplate and it charges fine without the case, fine with just the TPU portion of the case but when adding the hardcover layer, it will not charge. If you are doing this mod, it looks like we will need to stick with TPU cases and nothing with a thicker cover. I also tested my Spigen slim snap on case just like the one above and it will charge but its very finicky on placement. I have noticed that the charger does not activate unless it has the magnetic pull. This makes me wonder if a Qi coil would work for PMA if you used the magnetic disc to activate it. I am pretty happy with my setup now but maybe someone out there will want to try this.

I really think this magnetic disc may be a key to getting our phones to work with a Qi coil. I am not suggesting our phones will work with a Qi charger but just use the Qi coil to charge via PMA if you have a magnetic disc to activate it. By testing the 2 cases above, The Slim Armor will not work and I cannot feel any magnetic pull when placing it down on the pad. When I take off the hardcover, I can feel the magnet and it works. The Spigen Slim case is a hardcover as well and it reduces the magnetic pull a bunch. If I slide it off the center even slightly the charging pad will immediately quit charging. This tells me that the magnet is the key. Now I wish I had not sent the Qi charging back to the eBay seller and could try this with a magnet.

I saw in the wireless sticker thread where someone had ordered a 5 pack of these sticker and was selling them. I missed out on his deal but if anyone else decides to order the 5 pack, I will purchase one to try this mod. I am not going to do it now as I am happy with my current situation but I am willing to test if no one else decides to.
[G3 Accessories] iazybandit:
Even though I sold out, I made a post with a possible Group Buy. It's not definite but I'm trying to get a feeler to see how much interest there is for the stickers to help the community. I don't want to order 100 of these and be stuck with them for months or end up not selling anymore because other options are available. - http://xdaforums.com/lg-g3/accessories/feeler-buy-qi-nfc-sticker-t2827738
[G3 Accessories] Pilz:
What if you bought a very small neodymium magnet and used that? It would certainly have the pull needed though any case.
[G3 Accessories] awtryau89:
Well after a little more research, the magnet is in the charging pad and the disc in the back of the coil is just a piece of metal. So I was thinking about this but it doesn't help. Ultimately if I get a Qi charging coil and try this, I will just use a small piece of some sort of lightweight metal.
[G3 Accessories] Pilz:
I have a qi back but no PWA charger or I would gladly try this myself.
[G3 Accessories] sailindawg:
Hey guys,

My wife has an Asus Padfone X. It came out of the box PMA ready. AT&T threw in the Duracell charging mat for free like they should be doing with the G3. I bought the padfone at a corporate store.

My Galaxy S3 has a Qi back plate on it. When I put the S3 onto the PMA charging pad, nothing happens. When I put a strip of metal onto the pad to mimic the metal in the padfone and put the S3 onto the pad, nothing happens.

Seems to me that the magnets in the PMA charging pad are there to only help center the device into the charging coil, nothing more. If I place the padfone onto the charging pad slowly, I can feel the slight magnetic pull from the pad.

YMMV. Be nice to see something magical happen with the G3 under the same conditions, but I'm doubtful. Looking at the padfone pma reciever, it's very smooth like a Qi reciever. There is no metal disk in the middle of it.

Be great if the 3rd party manufacturers started selling pma recievers like they do with Qi, but that took about year for the Qi recievers after they were initially introduced.

I think the best solution at the moment is to do what the HTC M8 users are doing. Slipping a USB Qi reciever under the case to add wireless charging. It's cheap & seems to work with cases like Spigen Slim Armor. And it's available now!
[G3 Accessories] awtryau89:
What you are seeing is correct. I have been trying to make sure I have the thinnest soltion under my OEM back and adding the PMA coil to it makes it very hard to snap shut. So yesterday I decided to take the full sticker apart. The sticker is composed of the charging/NFC coil layer. It is transparent and thin. Its sticks directly to the case. Underneath that layer is a small disc used for the magnet. Laying on top of the coil layer is a decently thick layer of shielding. It seems to be a pliable metal. Then on top of that is the top coating of very thin plastic. To reduce the thickness, I took the shielding layer out. The case back fit much better. Then when I put it back on the charger it wouldn't charge. I put the layer back in and it charges. So all of these things work in conjunction somehow. Finally I did cut a small circle out of the shielding for the magnet disc and this reduced the thickness perfectly and the phone still charges fine. Ultimately someone will figure all this out and how it all works together. I stillfind it hard to believe though that we do not have Chinese mfgs making these PMA stickers and cards yet.
[G3 Accessories] Pilz:
I think it comes down to demand. The D850 is the only one with PMA so companies may not find it profitable to make PMA coils for it. I'm waiting to see what happens before I butcher a quick circle case for $60 because that's a big price to pay on top of the PMA charger.
[G3 Accessories] sailindawg:
+1 for the last two posts. If I get this phone, I will initially be going with the USB Qi reciever & a Spigen case. My car mount, home & work charging pads are all Qi at the moment. Don't mind switching standards if it makes sense. Of all these wireless methods, I like the idea of magnetic resonance the best, but it is still to new & cutting edge to be commercially available.
[G3 Accessories] torqu3e:
Some more technical details between the Qi and powermat (PMA) wireless charging standards...

When it comes to Qi and PMA, they both use inductive charging, but the differences are that Qi’s wavelength is 100-205kHz and PMA’s is 277-357kHz. Otherwise, the method itself is the same. The rest of the differences have to do with the driving forces behind each standard.

For those interested, you may want to read these

http://www.chipworks.com/en/technic...inside-the-powermat-wireless-charging-system/

Can someone with a multimeter measure the output voltage off the Qi charging back cover? Would also like to know which pin receives positive vs negative to see if one can get POS ATT D850 to detect charge, might be able to hack some way around to using the Qi charger.

If someone in the bay area is willing to let me borrow a Qi back and charger for about half a day even that would do.
[G3 Accessories] a_akash:
I am confused, Can someone help ...noob to wireless charging

Ok so i have a LG G3 previously had a g2 Both from ATT g2 didnt have wireless charging so i didnt care much but ATT G3 does. So my question is to get wireless charging on my LG G3 att i need to get a qi charging back from ebay..rip the pad of the back and attach it to my (current ATT back ) to get the QI charging working. If not can i simply get a quick circle case. Rip the front cover off so I have the PMA charging back without the annoying quick circle case. Please correct me if i am wrong.
[G3 Accessories] xryousukex:
You canNOT use any sort of QI on the ATT LG G3 phone. It something related to the hardware so if you stick on qi sticker and try to use a qi charger it won't work.

You will need a PMA charger and a PMA sticker that seems to only come with the at&t circle case sold by them.
[G3 Accessories] a_akash:
ATT wireless charging back without quick circle case..PMA tho.

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=151363848989

They claim it works as a wireless charging back with PMA for ATT.
[G3 Accessories] iazybandit:
Read the auction CAREFULLY. Their listing is confusing but look at what I underlined.

***This item is physically compatible with the AT&T model

but the wireless charging antenna is not relevant for the phone

. If your phone is AT&T, this battery door would not hinder your wireless PMA charging. ***

The next sentence says it would not hinder wireless PMA charging but the picture doesn't even show the 4 pins required for wireless charging.

I would avoid them at all cost. People have had issues with seller and receiving wrong item. Either way, none of these will work with PMA.
[G3 Accessories] sailindawg:
The only Qi solution for the AT&T G3 is the USB reciever sticker that fits under a case. Not a bad solution, but you give up the USB port, if it matters. Be nice to see more pma backs come out or just the pma reciever stickers. Maybe a time thing?
[G3 Accessories] a_akash:
Do you have a link for one of the qi receiver sticks that works for att
[G3 Accessories] iazybandit:
AT&T does not use Qi. They use PMA (Powermat). There are no compatible stickers available. The only option or mod that I can think of is buy a wireless charging cover from AT&T which costs about $60. Rip off the sticker and put it on the battery door.

Other option is buy a Universal Qi Receiver. It's like the sticker but it requires you to plug the thin receiver USB cable into the USB port on the phone in order to charge via Qi.

[G3 Accessories] a_akash:
sounds good

i dont want to loose my usb port.. but for now its a good alternative until i can get a pma back case ready to attach and no ripping needed.

[G3 Accessories] mixxxk:
I tried the usb qi receiver. It did work, however it charged super slow. And it fit inside the case I was using so it was hidden well. Then I got the folio case. Instead of ripping out the coils, I used my dremel and sanded down the plastic until it fit like the original. It didn't need to be perfect as I was going to put a case on it anyway. It fit quite well, charged no problem. Then I put my case on. No dice. It would not charge at all. I'm paranoid about a phone without a case, always have been. Hopefully i can find a bumper case out there and just get a tempered screen protector.
