Hi
I am looking for a way to charge HD2 without need to allways plug usb cable to mobile.
Inductive charging would be great, but we are not that far, but HD2 has power connector under his back cover, it is there for charging with car kit. Possible solution would be to use back cover with charging connectors and appropriate charging base. So I would just have to lay my phone on charging base without any connectors.
Is something like that on market?
Thanks
Martin
nope..........
There is in fact such a thing, but i do not know if it would work with the HD2.
I have seen something of that nature at cebit or something, really cant remember which computer convention it was, but it has been reviewed in various mag's
hxxp://www.berryreview.com/2009/10/30/gadget-of-the-week-powermat-wireless-charging-pad/
(change hxxp to http)
I have seen an inductive charging pad system at Carpone Warehouse in UK.
Technically, i suppose it would be reasonably simple for a company like Powermat, or other inductive charging manufacturers to make a replacement battery cover for the HD2 that ties into the contacts on the back of the phone, which were originally going to be used with the car holder, before it got redesigned, and allow recharging of the battery.
Well... Inductive charging... Would be nice.. But:
There must be a coil build in in the back cover and some regulator hardware. That is making the back cover thicker. This might be no problem if they do it right.
An other posible problem is the induction itsef. It is close to the electronics of your phone. What will happen with the signals and even can it damige the electronics?
I would like to have it, but only when it is tested and no risk of dameging the phone and disturbing the signals.
Well Powermat make back covers for iPhone, Blackberry, Nintendo DS so it can't be doing that much damage
has anyone seen a power mat backplate yet ?
I believe from the CET and CeBIT 2009 and 2010 technology was shown for the integration of current wireless charging in mobile phones. I believe HTC has added a second charging connection just below the battery, behind the battery cover. Perhaps a flat coid can be placed at the back of the current cover. The coil can be connected to the secondary charging connection. It was previously inteded by HTC to be used with a special battery cover that connected to the first concept model of the HTC HD2 carkit.
I believe Duracell or another battery company demoed a wirless charging system that could be integrated with current mobile phones. Maybe it is a start to look there?
Even if it worked for hd2 it would charge the battery at very very slow rates (typically @ less than 80ma)
I never have my phone charging through usb...only into my pc when im copying files or flashing Roms
I just got a spare Battery & Desktop Charger, as i work 12hour shifts (listening to music) it comes handy having a spare battery
As long as inductive charging is in it´s childhood-state it´s another waste of valuable energy.
Not for the single phone or person but taken together the ever increasing billions of users it´s a massive waste of resources.
Did You know that the worldwide use of internet (PCs, Notebooks, Netbooks, Phones, Servers, transmission lines, amp-nodes etc.) consume already more energy than worldwide car-traffic ? Should make You think ...............
Hello,
Two quick notes: The Palm Pre battery cover coil has its terminals on the correct side and very close to the charging terminals in the chassis of the HD2, given the amount of room in the chassis. Unfortunately, it looks like the EVO has a larger battery cover, and from the pictures I doubt that the coil assembly would fit length-wise under the HD2 cover. I'm not sure if there are electronics in the "tail" of the assembly, but if that could be removed I think it would be easy enough to find terminal block that would fit in the indent of the HD2. If you look at the Palm assembly you can see the bulge for the coil, the four bulges for the stabilizing magnets (?) and the terminal, I can't see what would be in the tail besides maybe a diode.
Unfortunately, though, the cover of the HD2 is made of metal, which I think would cut down further the efficiency of the inductive coupling of the coils, maybe critically so. If they're using 1A 5V supplies for the base, it might push the supplied charging amperage low enough that it wouldn't be useful. So I think that until someone fabricates a plastic cover, adapting the Palm Touchstone might be difficult.
I do have to disagree that the use of the principles of induction is anything but mature; these inductive charging systems are basically loosely coupled one-to-one transformers, if I'm not mistaken. Engineers made excellent use of inductive coupling a long time ago, if nothing else those tube amps that some folks like so much sure did.
Regards
Any idea what the order is for the contacts below the battery?
I have my palm pixi cover and touchstone. I plan to remove the cover and attach everything to a hard plastic back cover. I just need to connect it to the right terminals.

Unfortunately I have yet to find the pin-outs for these contacts. Please share them if you find the information.
You might get some information from this hack created by Derek Hughes. It looks like he has had a similar idea to yourself. Unfortunately he does not use the hidden contacts under the battery cover, instead he just re-routed the micro usb port, kinda messy and a bit impractical.
This hack was carried by many of the phone and tech blogs. But the links below are from Hackaday.

Good luck.
Can we combine or close this in favor of this one?

Didn't see any info about it here, so I figured I would chime in with some initial impressions.
The inductive back is a smooth texture, not crosshatched like the D4 is standard. It is a small distinction that I am sure will fade over time, but for now, it feels too slippery.
The inductive back does increase the thickness of the droid 4, it isn't a lot, but it is probably enough to make some cases not work. I still have to source an otterbox case to see if a) it fits, and b) to see if the case interferes with the inductive charge, I will report back when I find out.
I am at the office, so I cannot actually see how it plays with my energizer qi pad, hopefully it doesn't beep all the time like the verizon one reportedly does.

Let us know how it works!
And bleh, Verizon charging pad beeps constantly? That... seems silly, to put it politely...
Well I havent used the verizon pad, but that is what I heard, beeps all the time, beep on connect, beep on full, beep on release.
I have had my droid on the energizer pad and it works and there were no beeps.
I like that orientation doesn't seem crucial. I had my phone at different angles and as long as you get the blue light, you are good to go.
I did see a demo where Panasonic made qi charger with a moving coil
youtube.com/watch?v=an7lWob6ZrE
That would rock, as then you don't have to worry about placement (not that that is a huge issue)
Quick update about the charger
I am having some issues, namely the phone will indicate it is charging, the charge pad will indicate it is charging, and yet after hours my battery meter has barely moved. Interestingly enough the phone lasts seems to last quite awhile on 20% battery. I think something is goofy with the battery reporting.
I will likely fully charge the phone over usb and then discharge as normal and see if that "resets" it.
I also worry that on and after you remove the phone from the charge pad the back is INCREDIBLY hot. Hot to the point where I am worrying it is hurting the battery.
Does anyone have the safe temp range for Droid 4 batteries? So I can monitor it.
If things don't sort out this weekend, I will be contacting Motorola about my issues.
I wonder if they will tell you to use the 'official' pad...
Also, you could try downloading Battery Monitor Widget to see what is going on wrt charging and discharging, including (dis)charge rates.
According to Wikipedia, operating temp for Li-ion batteries is up to 158F...however, heat above room temp causes them to lose capacity. The more "full" they are, the more capacity they lose in hot weather. Temps north of 100F in conjunction with a full charge would cause them to lose a third of their capacity in a year. Continuing to charge them past the point where they're full causes them to heat up, and eventually enter thermal runaway, a chain reaction that guarantees they keep heating until they ignite. Modern devices of course are designed to sense that point and stop before it's too late; that's why a multi-cell battery may never reach 100% charge: If one cell is at 100%, the charger stops, leaving the rest at a mere ninety-something.
GEF
well at one point today, i think the phone did overheat and would not turn on for about 20 minutes, the back was quite hot. Since then, I had it fully charge on the inductive pad (energizer qi) and it was not hot and fully charged.
I will be angry if I am told I have to use the VZW pad, what is the point of a standard if they don't follow it?
As far as thermal runaway, the Droid 4 does auto turn off charging when it is full whether on the pad or usb.

Wow... You are making me reconsider the induction pad. It sounds great, but if it generates excess heat, that might be a bad tradeoff given the battery isn't replaceable.
Just received mine in the mail this morning! I haven't played around with it too much, just confirmed it works (charged from 90% --> 100%).
I don't know whether I have an updated version or what, but the beep isn't too bad. I would say my dishwasher's beep is louder. I can see it being annoying if it was in a bedroom or something, but for my office (at home) it isn't too bad.

Ever get the Otterbox case to see if it fits with the inductive battery cover?
No I have not found a verizon store that has one I can try on and test with a charging pad.
I know the inductive case makes it a hair thicker so I worry about both fit, and charging.
Droid 4 + Charging Back + OtterBox Does NOT fit
Sorry to jump on someone else's thread, but I have received an Otter Box case for Motorola Droid 4 and I also have the inductive charging back, and with the charging back on the phone, the rear part of the case will NOT FIT.
I have tried the plastic rear case itself without the silicone rubber insert and even that won't fit.
I have left a post with Otterbox support to see if they MIGHT be working on a new case, But, I don't hold out much hope for that.
I have not received my charging pads yet, so I can not say if the Droid 4 can be charged through the case or not.. When I get the pads I'll give it a try and report back.
Exactly how does this work? Does it plug into the usb port, or just replace the original back?
The reason I am asking is my daughter just recently broke the usb port on her Droid 4. I tried to get it fixed at a local computer/cellphone repair center, but they coudln't get the part to fix the port. Today I threw in the towel, and used my insurance.
I was told it just replaced the back, as far as the Verizon rep could tell, it didn't plug into the usb port, but I didn't want to pony up the money for the back, and a mat just to find out I had to replace the phone anyhow.
Contacts are internal
The charging back has 4 contacts on it that connect to the internal connections of the phone.

It doesn't use the USB port. That's actually why I got one. I wanted to avoid wear and tear on the USB port.
That being said, I'd see if Verizon would send you a new one? They generally will unless there is evidence of gross abuse...

Thank you both for your replies, but I already used my insurance. I already took it into Verizon to see if they could do anything for us at the store. When the representative that helped us saw that the case around the screen was cracked, he told us if we attempted to use the warranty that Motorola would have said the reason the port no longer worked was from being dropped, even though being dropped had nothing to do with the port coming loose.
She now has a protective case for it, and hopefully keeps it on there, so the warranty can be used if it has port issues like the first one.
I am still thinking about getting her an inductive charge back, to keep wear and tear off the port. She tends to have it plugged in by her bed, and randomly answers texts throughout the night.

That's the problem, if you get the inductive charging cover, no current cases will fit. Since there is no possibility of using an extended battery with the Droid 4, the case manufacturers ASSUME that nobody needs a larger case. The inductive cover is not common and therefore is too much of a niche market for anyone to make a case for it. I tried hacking up a regular case but it didn't work out.

inductive cover contacts
Can someone snap some pics of the contacts inside the inductive cover? Made my own out of palm touchstone parts now just need to wire it
Found a picture back on post #14
Did you get it working?
So i droped my nexus last night it bounced off my night stand on the way to the ground and when i picked it up it was off. figured wtf hitt the button.
nope it stayed off
press and held the buttons and tried to get it to reset ect. no go it was dead. connected it to the charger and tried again. got a back light but nothing else.
so did the non tech thing (smacked it a few times and pressed the power , came up flaky screen was kind of scrambled. great i trashed my nexus by droping it.
so called Google they made me do all the stuff i already did, no surprise its dead.
they told me to call asus for support. , went to asus site they wanted my sn to make a case, couldn't find find it i know i registered it. they told me i would need to send it in they would charge me 65 to issue a new serial number WTF! and then if the repair was not in warnty it would cost 165 to fix the nexus. 65+165 is more than a new nexus 16 (what i have). so i said thanks but no thanks.
so as i sat and stared at my paperweight i thought why not. i got a razor blade and a butter knife. used the razor to crack the edge of the case off and then popped the back off with the butter knife.
looked around and noticed those wonderful overworked china drones routed one of the wires for the battery round the backside of a plastic support pin. this made the wire very tight and it pulled the connector off the main board on one side of the battery connector creating a short. i pushed the wire on the right side of the support pin and reset the power connector and bam nexus back to life.
so if you dropped your nexus and it boot loops and or just wont turn on when off the charger. open it up and check the battery wires bet you got the same cross eyed Chinese tech and the battery unplugged itself
Thanks for the tip. I use a TPU case for my Nexus 7.

Drop it (multiple times), smack it around, then take a RAZOR BLADE to it?! Good lord.
No surprises here.... None at all....
Cool story bro. Glad you fixed it. I fix most of my stuff too. I'm a techy guy and probably more qualified then the drones that work at the factories.
Just like my wife's Samsung Netbook (back when netbooks were cool). She insisted taking it out by the bonfire where some friends and I were drinking. I told her countless times to take it in before a full glass of red Merlot gets dumped right in the keyboard. She runs inside and plugs it into the wall??!!!
I took it apart and cleaned it up but the keyboard was hosed. I called Samsung for a replacement keyboard but they wouldn't sell me one. I had to send it in. When it got there, I got a call about purple stuff in there and thus the warranty was voided. I said yeah no ****, I told you guys we dumped wine in there. She wanted to charge me $75 for the keyboard and $125 an hour. I laughed and said I only paid $220 for it, for $200 I'd rather buy a new one and see if the old one would Blend.
Bought the keyboard off eBay for $16 and she still uses it like 4 years later.

On the G3 there were (supposedly) OEM stickers, or you could buy the back covers with them already in (supposedly also OEM) I got one and put it in myself and it worked great. Just gotta wait for then to come around. probably wont be long.
Yeah there's a post on this section about some stickers already available from China, but nobody has reported back yet on how they work. Plus I think I'll wait till an actual back replacement comes out. What I'd love is a good sturdy case that protects the phone while replacing the back at the same time. You'd have the benefit of a strong case, with a slim profile. Kind of like the quick circle, but beefier, and without the flap.
I know that the Quick-Circkel case has Wireless charging in it.. But you probably don't want a flap on your phone.. #flapphone..

Yeah you're right. I wouldn't mind something like the quick circle, minus the flap. Because it seems like it's about the same thickness as the normal back. Then i could put a case on top of it. But yeah I don't like the flap, and I want a sturdy case. And I want wireless charging. I want it all! :silly:
I gave up looking for the LG G3 and then they apparently came out. LOL. I had a sticker for my S4 and it worked nicely, but did add a little bulk to the back. There wasn't much room for it.

Yep, I'm with you. I'm going to wait for something on Amazon. They always take care of me.
There have just been too many horror stories for unauthorized 3rd-party accessories (especially with iPhones and iPads), but not unheard of with other brands where damage was caused by unauthorized adapters, chargers, wires, etc. Not taking any chances!
Agreed 100% here.
I would love the new G4 but the lack of Qi is pissing me off. I can't understand why they don't make this standard. If you have never used Wireless Charging, you may think it is a stupid perk, but let me tell you, it is not. I have wireless charging pads on my desk at work, home, and bedside. I use the Nokia Qi Charger with multipoint that allows me to pretty much plop it down any way and it starts charging.
Sure it isn't a QUICK charge (which sucks btw, slow charging is better), but amazing... especially bed side.
I am looking online and only see the Folio cases which are absurdly expensive. NO Way am I spending $60 for a feature that should be there in the first place. The little QI coils are basically a single thin strand of wire.
Plus I want an OFFICIAL backplate... and it also (hopefully) doesn't add additional thickness because I want to use a Feather case.
Guess this purchase is on the fence. My G2 is still rocking. I am in no hurry to get rid of it.

Man you are preaching to the choir. I decided that wireless charging is a must have with my next phone, partially because the charging port on my old phones always wear out from my incessant plugging and unplugging, but mostly because of how frigging convenient it is. And like you, I was also pissed to find out the G4 was not coming with it so I was seriously considering the Galaxy S6. But I was still on the fence because of other features on the G4. But the free 128gb SD card and free battery, cradle, and 32gb SD card threw me on the G4 side. And I am glad I did. Loving the phone. Typing on it right now. [emoji3] But I will not be set back. I WILL have wireless charging, I'm just going to have to wait a bit. Even if I have to buy the quick circle and hack off the stupid flap. Wonder if a normal case would fit on it then? Also don't want to spend $50 on a case only to rip it apart lol. Anyway. C'est la vie.

I'm in the same boat... Coming for a VZW G2.... I need wireless charging on my G4!!!!!!!!!
I also have a VS980 and want the G4 but would be really annoyed not being able to use the 4 wireless chargers I own!
Wireless charging backs and stickers will be available soon. Just be patient. The phone just came out in the US.
Did they ever come out with a back for the G3?
Yes. Just did a simple list on Amazon: http://www.amazon.com/s/ref=nb_sb_n...ords=wireless+charging+back+for+lg+g3&x=0&y=0
Not sure if it will be any good but I have ordered on to see
http://www.ebay.com/itm/USB-Type-C-...986680?hash=item4d44193db8:g:g2UAAOSwt7pXNIHp
There only seems to be one type ATM
and it supposedly charges at DC 5V/1000mA (depending obviously on the transmitting charger)
It's available from Amazon as well but they all link back to China
Early days, here's hoping I don't blow up my 5X
Yes it blocks the USB port but I always SMB stuff from my nas box so that's not a problem.
You're lucky if you ever get even 500mA out of it. Every Chinese Qi pad vendor overstates the power on their product. Still, nice to have the option. Let us know how it goes

Iiinteresting, ordered one of those through Amazon. Even if it's only 500mA it'll be nice to have, I just hope it doesn't mess with NFC stuff. Looks like it shouldn't given that the antenna for that is near the camera according to the manual.

The receiver coil looks bigger than the ones I've seen before so maybe 1 amp is a possibility, i'll let report when it eventually gets here.
Quick review
Got the pad now and here is my initial review
Clearly the photo on the advert is a bit of a lie as the coil is about half the size as you can see in the photo below.
The pad is situated to far too the top on the Nexus 5X and sticks out where the fingerprint reader is. This can be easily fixed by cutting a bit off the top, as the coil does not come right to the edge this can be done without ruining the receiver.
THe bit that plugs into the USB socket sticks out which is a bit annoying but not the end of the world.
On my Zens dual Qi charger it took just less than 4 hours to charge from 36% to full so it's not super fast but not that bad over night. The phone indicated slow charging and was AC charging by the battery usage page.
It seems to have no problem staying connected as long as you are aware where the coil is on the pad (towards the top) and has no problem charging through my case
It does not appear to interfere with the radio antenna at all so thats ok.
Also it's super slim so should not interfere with most cases
So in conclusion its fine for me as I rarely need to charge the phone except for overnight, and I have not been using the faster charger anyway.
In case anyone is wondering the case is a Nillkin Matte Super Shield Hard Shell Case which is super nice though the black was a mistake

Nice, thanks for the update. I'm still waiting on mine, it'll be nice to have wireless charging again.
edit: I did get mine today... it's a bit flaky at best, currently i'm blaming the qi charger, i've got a different one on the way.
Good to know it fits under a Nillkin case, as that's what I have for my Nexus 6P. I ordered a receiver on the 25th, hope I get it soon.

The charging on mine seems rock solid but the zens dual does have a pretty big target area to put the coil in.
See the screenshot below the charge looks pretty rock solid

While fiddling with it the qi pad I have it only really works when the thing is outside my case in one exact spot. So... given that it worked fine for someone else I went hunting on Amazon and found a better looking unit.
We'll see Saturday when it gets here if I chose the right one.
Woot, got a full charge overnight with the new qi pad so that old pad is basically crap.
How thick is the pad? I'm wondering if it would be possible to remove as many unnecessary part from it and try to fit it under the back cover of the phone. And also solder it directly to the charging board so that the USB would be still usable

it's not very thick at all and any generic Qi receiver would probably do as a few people already have.

There is padding over the battery on the back case you can remove if it's too thick
Has anyone else been having problems with theirs?
For a couple days now it's charged to full and then the next morning it'll be less than 100%. Yesterday it was at 89%, today it was at 93%. I did verify it was at 100% yesterday before I went to bed.

I don't have one of these, but I might have a possible explanation. I used to use a 0.7 amp or 1.0 amp charger for charging the 5X overnight. Seemed to work at first, but then it started showing less than 100% in the morning. What seemed to happen from the battery graph is it would charge to full, then start draining (slowly) and not top up again. So I think the low power just didn't trigger it to start charging again once the battery drained a little.
I put it on a 2 amp charger and it now is 100% in the morning. If your phone acts like mine, it might be due to the lower power from wireless charging.

Yeah.. I was kinda thinking that a little, good to see it confirmed. Not sure how much the pad was getting but the sending unit was only drawing ~1A so that's the issue there...
Oh well, it was a nice experiment, would have been better had it actually worked though. Back to the included charger it is then.
Just a note from years of experience with these Qi chargers:
There's some inherent loss in efficiency. Essentially, your wall charger is working to spin current around in a coil, which then by magnetic induction causes current to spin around another coil (in your phone), that then feeds into the battery. It's indirect, there's no contact, and some phone materials can even impede it (just one reason these stupid metal wannabe-iphones luddites keep demanding are a terrible idea ).
Bottom line is - you need a charger that's over an amp, closer to 2a if possible, to spin some of these Qi chargers up enough that it makes a large enough field to get to the Qi coil in your phone and charge it efficiently. Ones that come with tablets seem to work fine - I have my Nexus 7 charger on my office Qi (which is angled and serves dual duty of holding my phone for easy reading and viewing).
I'm actually more interested personally in an internal Qi option - solder it in, invisible.
True story - I did that with my S3 before I got an S5, and it worked great. Didn't have to bother when I got an S5, since they sold an optional Qi battery door for the S5. ...don't get me started on my hatred of the design philosophy that excludes removable battery doors.
Anyway - I just picked up a 5x, reluctantly ditching many of the features I had on my S5, to try Google Fi service out.
Wireless charging is something that I'm very interested in - I have wireless chargers literally installed (meaning: hidden, routed wires) in my car, office, and house, specifically to avoid that dorm-room spaghetti-everywhere aesthetic. "Wireless... it's not just for convenience anymore."
Hopefully there's a thread with step by step instructions on a good Qi pad and identified soldering points to install internally?

Such a thread exists. Someone also offers a service doing the soldering for you. I might be able to find it...
Here is the mod:

EDIT: why did you mod your S3 when you could have dropped this in?
Sent from my SM-G930V using Tapatalk
That may exist today, but certainly didn't exist when the S3 was the current flagship phone.
Back in those years, the popular (and nearly 'only', here on XDA) modification was to buy the Palm Pre battery door and charger (non-Qi) and use those parts.
Since Palm had recently gone bust, $20 would get you all the parts you need - including Palm's proprietary charger base, a receiver sticker, even a charger.
And honestly, I have to say the Qi charger gets much hotter than the Palm system, so there might be an argument there for it being technically 'better than' the Qi systems. Qi is simply the standard today.
So now with the news that there are some accessories(chargers and cables) that are not compliant with the USB type C specifications, I wonder if these wireless pads are compliant with the specification?
