I modified my Galaxy Note to use inductive charging via a palm touchstone / patch.
Just a quick note. Not a whole lot to contribute here, because I largely followed the examples of the Qian Qi. That guy is awesome.
I don't think I voided a warranty, either. Only minimal teardown required (black plastic back, then the speaker section). Never came across a sticker I had to remove....

Notes:
- Buy a good soldering iron. Weller WESD51, set to 610 deg F, with 1/32" long conical tip, with lots of flux and lots of flux remover are the only reason I could do this. I can't stress enough the value of having good temperature control, knowledge of temperature, and so forth. I stumbled around with an "ordinary" soldering iron for a long time, and in hindsite, I can't believe I did so.
- Do not choke on the price. I already had a lot of soldering gear, and I bought $220 more. Spend the money. It's worth it.
- Watch the curious inventor youtube videos on soldering. This guy. Watch everything, several times. http://store.curiousinventor.com/
- You want 30 gauge wire. It's the only thing that just barely can be crammed in. I used the "Kynar" coated type. Buy at least 2 colors.
- as you look at the phone disassembled, with speaker on the bottom left, the +5 pin on the micro usb (MHL) port is the leftmost. I attached a wire to that, and a ground wire to the housing where the port was soldered.
- routed the wires under the speaker, then back, then into a VERY slight indentation into the battery compartment. used a blue "safe open" tool to help shape the wire / crimp ends. Once in the battery compartment, you're golden. Attach the inductive charging coil to the back of the samsung plastic back, add solder to the pads, and attach the wires.
- Attached is a picture with roughly how I routed wires. Red is +5V, Blue is ground. Be sure and double check if my recollection is right where the indentation is into the battery compartment. (that part is by memory).
- dont leave too much slack. it's really hard to get the samsung black pastic panel back on. Mine very slightly bulges.
- be careful where you put the charging sticky patch, because this phone is a little bit bigger than a palm pre. You have to consider if the phone can sit on the charger and "lock in" with the magnets. If you place it too high, it actually can't (in portrait)!
- Qian Qi had a really interesting point: most articles about how Li-ion batteries behave are wrong, and fully discharging the battery drastically reduces the number of cycles you have. So this is actually a very useful mod--whenever you don't use the phone, toss it on the charger.
Thanks for summing it up! Was actually thinking of doing this mod myself. Question: do you have a protective case on your Note? If so - what kind and how badly does it affect the magnetic properties?
No case. Especially because the note is so big, I think it would be unmanageable.
I took the samsung thin plastic back, and placed the Palm PRE (with charging coil still attached) on top of it, on the touchstone -- to figure out proper placement & mark with a pencil. I noticed a buzzing sound, coming from (I think) the induction coil on the palm pre back itself. I suspect if you use a case, this wont work well.
Also, the size/weight/placement of the galaxy note are such that the magnets are just barely strong enough to hold it. One time my phone was near, but off, the charger. I'm not sure if vibration from the phone did that, or my kids
In summary, I'm not sure how well it would work with a case. You might be able to research this on the net; among the 15 or 20 people that have bought a Pre, you might be able to find some info about the effect of a case on inductive charging.
tight squeeze?
im wanting to try this mod i have my touchstone on the way not thank you amazon but it seems like to me that the pad from the pre wouldnt fit under the cover of our phablet =/ could you post pics of the finished product and i think this is the only instance that i have seen someone attempt this with the note and i want to try it i love my note but would love it even more with inductive charging.
I am not the original author but I performed a different Touchstone mod and posted pics here:

Thank you!!!
Thank you so much for your post I have my materials on the way but I hadn't seen a detailed guide for the note other than this one and was worried I would have to solder directly to the usb pins which looked scary lol I did have two questions though would your mod work the same way for the at&t note? Specifically the points where you soldered to the phone and can wireless charging be performed through a case?
Hey, OP here. You may want to hold off just a bit. Mine is exhibiting some issues now. As in, it says "charging" but it doesn't do so wirelessly. The phone will stay "charging" but the battery % never goes up. (It was slow before, but would charge fully over a night).
Charging via USB still works.
It may be something simple; I'm not sure. But I need to crack it open and take a peek, and I haven't had time to do that yet because my phone is functional at the moment.
If nothing has conspicuously changed, there may be something about the design that isn't sustainable. Or maybe my solder joint halfway broke, or one of the wires got smashed enough so that it's partially broken...
I'll write back with my findings. Bug me if I don't
Thanks for the notice I was about to pull the trigger lol tbh I probably shouldn't attempt this I've never done a mod like this before and I'm not exactly a surgeon with a soldering iron lolvthatvbeing being said I'm going to attempt this on an old evo 4g I have before I do surgery on my baby lol plus I'm already familiar with the guts of an evo from screen repairs ill report back with my results

No prob I just wanted to see if i could do it and if I can do it with little soldering experience I'm sure most could do it I haven't done this mod to my galaxy note though as there is way less room in its a far more complicated mod than the evo because you have to make room for wires in a device samsung made as thin as possible and the way you have to route the wires I feel like the solder joints would just break

For those who want to try this out but still have warrantee just buy a backcover, a micro usb plug and assemble it according to the directions here.If you need the note just take out the usb plug and the back cover and you're good to go.... Or leave it there.....
For those who don't know what pins to use on the usb plug:
Pin: 1 is 5V+ (red)
Pin: 5 is GND (black)
Works like a charm.......

I was not a big stylus user; I can't stand the input lag. I didn't notice a difference, but I always considered the input speed unacceptable. Not sure why there would be any difference, anyway.
My big problem that I've never taken the time to address is that after some time, it's as though I can't pull enough current through the wires to charge. One day I need to crack this open & figure out why.

Hi all does the note 2 support inductive charging or do you have to replace the back? Its just I notice there is something in the back cover and i hear this is NFC for payments I was just wondering if it was also capable of inductive charging out of the box or if it has to be adapted in some way.

If it does support this, I wonder why Samsung hasn't mentioned it in their presentations or included it within the official specs? Hope it is possible though.

Soo... here is a picture of the back... and yeah... i also think they have at least integrated the connectors for wireless charging into my note 2 xD

Out of the box it does not support wireless charging. I suspect it could be modified to use a Palm inductive charger though. I've been messing with my Note 2 and a Palm Pre inductive charger for the last half hour or so. The PCB of the Pre back cover fits into the little groove next to the micro SD slot (I had to cut a small part of the PCB off - see the red circle in the last image) and the coil/magnet cluster fits very easily between the back cover and the battery. Visually/tactilely it's pretty much impossible to detect when they've been put in there.
Unfortunately, I've never modded a device to use inductive charging before so I'm a little hesitant to proceed.
wow... that looks very good ...
Hmmm but without a technical background I would not risk that... you have at least to measure all that stuff ...

i would rather not to do it, i think note 2 is the ame as Galaxy s3, they have the capability you just need to wait for the battery cover replacement sold. or you can take buy one fro S3 and rip out whatever in that back cover (coil) put it in your note 2 back cover. http://www.androidauthority.com/wir...samsung-galaxy-s3-hits-verizon-stores-105433/
Its all just my theory though.... for me better just wait rather risking my gorgeous note 2 which is note yet in my hand right now....
Hello guys,
Former Palmer/webOS user here. Actually, toying with the inductive back of Palm Pre & Touchstone charger, is not that risky nor difficult, not at all. I've tested it as a kind of proof of concept, with my SGS 2 - just put the coils/PCB assembly at the back of phone cover, and soldered two wires to the coils's output contacts. These two wires, I just ran to the micro USB plug. When I've connected that plug to the phone's micro USB port and put the phone on the Touchstone charger, it starts charging - that's all. Coil's integrated PCB sorts out things like converting AC/induction back to DC, 5V etc. What you are getting out of it, is your pure, standard, USB-compatible juice.
The only reason why I wasn't using it permanently, was that I didn't wan't to solder anything on my SGS 2's PCB (didn't feel like it is a smart idea, with it's tiny tracks and my soldering skills - or rather the lack of thereof). And having micro USB plug stuck in phone's bottom all the time, didn't appeal to me, somehow
But if the SGS3/Note2 already had the required contacts behind it's back cover, it will be a breeze DIY project. And one damn handy and cool-loking charger on your desk, believe me.
I'll try to post some photos of my POC setup later on.
Best regards!

I purchased a couple of kits - one was just the inductive charging module for the phone, which I installed and separately picked up a couple of charging bases; the other one was a complete kit.
This kit (not by this seller, but the photo is the same as the kit I purchased) is very elegant, thin, and easy to install. You can barely see the bulge in the back of the case. The only problem I have is that the magnets seem to be slightly too weak so the position is a bit inexact. I've added a couple of extra magnets but will end up replacing the originals with my slightly-stronger replacements in the end I suspect. Overall this kit, although expensive on Ebay does the job and looks good.
This charging module was easy to install but the one I received had the polarity of the charging pins reversed so I had to make a modification to get it working. Here is a post of my preliminary mod to get it working; since that post I've done some clean-up but the one linked above thinner so I'm using it as my primary right now.
Maybe this help!!!

Don't need to get a new battery door. That new Samsung door will actually be larger than the current one. Some/many cases won't fit.

I pre-ordered the one for the S4, after it was written up on Engadget. It hasn't been released yet, apparently, so I'm still waiting.
Here's the Engadget article. Some good things said about it in the comments:

Samsung is terrible with the S4 accessories.. they release a new battery cover just to enable wireless charging.. ok fine.. but they release a stupid 70bux transparent flip cover that doesn't support wireless charging.. so basically i can never get wireless charging if i ever want to use their oem products or i need a special case if i want to use their oem wireless charging cover and fit?? real smart thinking.. guess i'll give this kit a try too
I thought it was the battery it self that has a coil in it for the NFC and that was for charging?
if not I have my palm pre still that has that wireless charging - could I take that battery cover apart and take that coil out and just attach it to the inside of the phone
I dont see anywhere where a battery cover with this built in will connect inside like it does on the palm pre, there arent any contacts that I can see that will go to the battery charting how would this work

Are you sure you are looking at a GS4?
There are 4 contacts. 2 to the left and 2 to the right of the flash. I think the left ones are for charging. I am basically ready to do what you said but need to figure out the polarity of these contacts.
There are other related threads but no responses yet...

To the guy worrying about the flip cover - there are tons of wireless charging inserts on eBay. You don't need the Samsung back, just get one of those things and stick it under the cover.

I'm hoping yours worked. I've had a qi receiver in my S3 for about 6 months now. I pulled it out to see if it would work in my S4 and it doesn't quite fit. The pad would fit, but it lays over the sim card and mSdcard, which probably wouldn't be a big deal, but the problem is the two small brass contacts don't quite fit in the square charging holes on the s4, they're probably 0.25mm too large and slightly to far apart for the S4.
My S3 pad is about 6 months old though, so hopefully the newer s3 pads have been modified to work with both phones.
I love wireless charging though and just went ahead and ordered a qi pad for my s4 from the fastech link earlier in this thread.

I've been searching and searching for good battery packs, but I really don't need anything more than 1 full battery life for my N4. I would actually like it if it can fit my pocket, with the cable and the phone.
What's the best and smallest external battery pack?

Smaller than the phone and has the micro-usb plug built-in.

Or you could get the Zerolemon battery case. $41
I recommend the Anker. Not enough juice for my taste but the size and built-in cable are fantastic.
More battery packs should have built-in cables IMO
I haven't tried this one, but looks very good and portable.

It's a very functionally thing. I love it.
like the integrated cable - I have bought 2 NewTrent external powerpacks over the years (I lost the first one).
Also available on Amazon, and they are often heavily promoted. They are good quality, and have a huge range of capacities available. Though unless you are planning going into the jungle for a week, I would get something in the 3-4,000mAh range.
That is 1-2 days' heavy use, and since capacity is lineally proportional to size and weight, you get that capacity for about the same size as a normal smartphone.

I've been using this powerbank from Nokia.
Didn't want to get an unknown brand especially since we don't have removable batteries that we can take a risk with.
Been using it for a month now. Gives me about one full charge. Very reasonably priced for what it does. Would recommend.
Hi everyone,
I have had my Nexus 4 for over a year and have noticed that the battery just doesn't last as long as it used to. So I ask, those who have replaced it, is it worth it and do you see a difference? Also, can you fit a larger battery inside with the glass back still intact? Like maybe a 2500 size instead of the stock 2100?
It's not worth it until you rule out other causes of the battery draining. Software is the problem 99 times out of 100. You should only ever replace the battery with an original one.

After about 500 cycles, a lithium rechargeable battery will have lost upwards of 20% of its original capacity. If you charge more than once a day, you could have reached that point by now. A new battery is about $20 off eBay. I can't comment on the difference it actually makes because I got my Nexus 4 with a broken screen and replaced the screen and battery at the same time.
You can also extend your battery life by flashing a custom kernel like HellsCore (which is slightly undervolted) and play around with underclocking, undervolting, different governors, and running on fewer cores. For example, I've kept mine at a dual core 1.2GHz with intellidemand governor (CM11), and it still runs smoothly most of the time, with only the occasional hint of stutter. And if you want to play a game or something, just crank everything back up. And of course there's the obvious battery-saving methods, like turning screen brightness down, disabling GPS/wi-fi, synching less often, and limiting data to 3G instead of 4G. Plus the less obvious methods like Greenify and/or Tasker.
To my knowledge, there's no higher capacity batteries, or even external battery cases for the Nexus 4.

After about 500 cycles, a lithium rechargeable battery will have lost upwards of 20% of its original capacity. If you charge more than once a day, you could have reached that point by now. A new battery is about $20 off eBay. I can't comment on the difference it actually makes because I got my Nexus 4 with a broken screen and replaced the screen and battery at the same time.
You can also extend your battery life by flashing a custom kernel like HellsCore (which is slightly undervolted) and play around with underclocking, undervolting, different governors, and running on fewer cores. For example, I've kept mine at a dual core 1.2GHz with intellidemand governor (CM11), and it still runs smoothly most of the time, with only the occasional hint of stutter. And if you want to play a game or something, just crank everything back up.

It's not worth it until you rule out other causes of the battery draining. Software is the problem 99 times out of 100. You should only ever replace the battery with an original one.

Thanks for the replies.
I've tried software tweaks, kernel tweaks, everything, greenify all things in that sorts, different kernel profiles etc. It makes a difference but still not as good as it used to be. I might as well try replacing it, I can always put the old battery back in if I want, not that hard to change. There's a Galaxy S3 battery, I think its the same size, not sure with a higher capacity, same size, same voltage etc I could go for that if I wanted to :good:

Have you seen what the N4's battery and connector looks like? That ain't gonna work. It won't fit, for one thing. Wrong shape, and the N4 battery is pretty slim because it doesn't have a stiff protective covering (it's actually kinda flexible - be careful prying it off the adhesive) and even if you found a battery that did fit, you'd have to rig up some sort of splice for the connector, which would probably take up more space, defeating the purpose of finding a higher capacity battery.
I did find a couple battery cases. There's the Mugen 4500mAh, but it's both freaking huge and freaking expensive (nearly 1" thick, $90), and the ZeroLemon, but it's also freaking huge, only has a (removable) 2200mAh battery, and I can't find one anywhere actually for sale.

Yeah I've seen all the cases already. Too big. I don't mind doing surgery on the battery to make it work but only if I can find a higher capacity one that's gonna fit I'll consider it.

I've thought about trying getting a new back cover (minus the glass), cutting a chunk out of it, and rigging up a larger capacity battery. It's the connector that stops me (that, and my lack of knowledge and tools to do so).

Just do this. This is where I got the surgery idea. Bit complex but it seems like its worth it :good:

There is no way you're going to put an s3 battery into a nexus 4 and have good results, please put any notion of this out of your head now, it's pretty absurd. Also you may struggle to use your original battery after replacement, a lot of people damage it during removal.

Look at the above thread, its possible and doable, not absurd.
I'll be careful when taking it out, its easier with a hair dryer because of the adhesive under the battery

Anyone who did it is an absolute idiot, but whatever, melt your phone and burn your face off if you want. Notice how there are no follow up posts from anyone even a month down the line in that thread, I think they all died (but seriously, their battery is ****ed now and they're too embarrassed to post anything)
But here's some videos of lithium batteries exploding from incorrect charging

Also the fact you want to use a samsung battery has me even more concerned

I agree with what DrFredPhD said, LIB are very dangerous if tampered with or altered physically.
If you're really having drastic differences in battery life then you're supposes to then I would suggest you replace your N4 battery with an original one itself, don't go for any other options

Yeah, running/charging multiple lithium batteries typically isn't a good idea. But the videos that DrFredPhD posted aren't what you'll get with a cell phone battery.
Li-ion and Li-po batteries in commercial devices have built-in circuitry to prevent overcharging, overdischarging, reverse polarity, and short circuits. If you short it, the circuitry kicks in and kills everything. Putting it back in the device/charger resets the kill switch. Same if the charge gets too high, or the discharge gets to low. Circuity switches the battery off, and prevents overcharging and runaway discharging.
Those videos show batteries that don't have that circuitry. Either it was removed, or they're cells used by hobbiests and were purchased unprotected. Unprotected cells are available for hobbiests (R/C stuff, high-powered flashlights, etc) and some use them because the circuitry in protected cells leeches a bit of your juice. In an R/C car, that could mean a few more seconds and one more completed lap, in an R/C plane or helicopter, a few more seconds of air time before you crash. But there are obvious dangers.
Those dangers don't exist with commercial protected batteries. Well, they do, but that's when you buy a cheap knock-off from China, or the cell is defective, like those Sony and Dell laptops that were catching fire several years ago.
But even with protected commercial batteries, problems can occur (just not explosively dangerous ones). If the cells are mismatched in capacity, or one has a higher charge than the other, the higher capacity one will try to charge the other one, and the battery life of both will suffer, plus since they're also trying to power the device or receive a charge, they'll get really hot and can be damaged. Running identical cells is one thing. Charging should be done separately so that they start off the same. It's not the same as with a laptop or electric car, because they have additional circuitry to make things safe. It's also not the same as using a battery bank to power/charge your device, because effectively, that's just the same as plugging into a USB jack.
Battery Monitor Widget Pro is reporting around 1700mAh or less to me now so I'm wondering if my battery also needs to be replaced... Happy to use quality OEM but can it be done myself or should I pay someone?

You can replace it yourself. You'll need a T5 TORX driver for the screws at the bottom of the phone, and then something thin to pry the halves apart, preferably plastic so you don't damage your phone's body. It helps to heat it up with a hairdryer to soften the glue.
As for that app, I don't know if I trust it.
