Induction charging has the same charging speed as plugging it into a wall outlet. Very fast!
Sidenote:
I tried using a multimeter with the 3 contacts located under the battery and could not get it to register anything (with and without the charger plugged in). I then tried shooting 5v through it using 6 different combination (2 plugs for 3 contacts) and still couldn't get anything. If anyone knows a way to use these 3 contacts for charging please leave feedback. Also if anyone can find a minature microusb male connection that'd be great.
Well done, it's a really nice mod!
The 2400 mAh is a bit too bulky for me, though the extended uptime must be awesome. I'd even consider something similar, were it not that you're using the microusb to charge. If only you could connect it straight to the battery, would be so much more convenient. It'd still work in for instance car kits and attached to a pc.
Never the less, well done.
Looks great, i would try this myself but i cant stand the bulk of extended batteries and the stock metal back would almost defiantly interfere with the current. Where did you get the decal from?

You can't plug in directly to the battery since the battery doesn't have a balancer board on it and it would explode if it were to be overcharged without one.

I got the decal in the automotive section of Walmart. It came with 2 big/4small stickers for 7usd
UPDATE: Made the microusb head smaller! Letting liquid electrical tape dry then I'll post pics.
this is a really nice mod. what about the possiblly of going via the nav panel connectors instead of micro usb. this would as far as i know leave the usb port free and also not have the disadvantage of having a usb connector attached which can be easily damged.
Personalyu i wouldnt do this mod as i use my phone to tether a hell of a lot so it seems pointless to me, but being able to just sit your phone down and have it charge is awesome.
Great work!!!!

I tired the navpanel connections with no success. If anyone has a multimeter please try to do it to theirs (with charger plugged in).
that is really odd....only think i can think of is manye theres something that needs to happen with the middle pin.
nice work i think that decal are very cute indeed!
PPL this is knowed from a long time! This pins are used for example with Car Kit like CU s400: http://www.slashgear.com/htc-hd2-cu-s400-car-kit-gets-priced-detailed-coming-december-1360143/
This car kit is in two versions: like this on 1st photo - use other battery cover which use this "mysterious" pins to run NaviPanel and charging battery and 2nd version with charging via microUSB port.
I hope this helps a bit.

This "odd" middle pin you can find in every phone battery too. If you depart any battery you can find there a little electronic circuit.
I think, that this pin is used to metering battery charge, but i can be wrong - im not advanced in electornics.
I'm well aware of the existance of these products but cannot figure out what the three contacts below the batteries are.
Maybe some users having one. In that case he/she can make photos of all connectors or better - check it with multimeter which connector is +, - and this middle one.
Maybe some service manuals can tell something more abt this. I searched for it and i did'nt find nothing useful.

I also did a search on google and xda but with no luck. I don't think it inputs 5v into the machine since I did shoot 5v into the 3 connectors using different combination.
Hi all,
The contact closest to the center of the phone (looking along the longest axis of the phone) is the +5V, the one furthest from the +5V is the ground, and there's a small voltage on the center contact, positive to ground. These +5V voltage shows up (on my phone) only when the mini-USB charger is plugged in.
I've got the +5V terminal of the Pre plate attached to the +5V contact on the phone, and the other one attached to the GND contact. Inductive charging works at 341ma (as measure by the hardware and read by BattClock) at maximum, which is probably not coincidentally also the limit set on USB charging, at least from my laptop.
I tried hooking the Touchstone up to a Apple ~1" cubed charger, didn't get any charge. I haven't read the USB power specifications, but according to the people at the Palm forums you have to have a USB spec power-capable charger to initialize the Touchstone, and the USB ICs signal this by connecting the two data lines. This can be approximated by clipping a USB cable and twisting the data lines together on the Touchstone side of the cable. This allowed the Apple charger to power the Touchstone.
The HTC stock charger works fine, as does an 800ma Verizon charger I had laying around. I tried hooking the Touchstone up to both a [email protected] switching charger and a 5V 8A supply, the Touchstone still charged at 341ma. I'm guessing this is software, firmware or hardware limited, just like the computer USB connection. I would speculate that if you shorted the middle pin to the ground pin, it might remove this restriction. Or fry your phone, I didn't try it.
There's a guy on the Pre forums who got the Touchstone to consume about 1.02A (http://forums.precentral.net/palm-p...b-adapters-touchstone-dock-2.html#post2020491) so the thing can, apparently transfer some power. I don't know how long it would last at those wattages, but I'm going to read a bit on the USB power spec and see if the 341ma limit can be lifted.
It's kind of nice to use the internal connector, because it leaves the microUSB port open. If anyone has any questions feel free to ask. With the relevant portion of the Pre cover stuck to the back of my phone, there are no wires out of the chassis and the added part doesn't add any considerable bulk to the phone. It protrudes less than the camera.
Anyways, hope this isn't a thread-jack or too long, but I figured it might help anyone that's going to take the time to do this.
Thanks to the community here.
Did you dremel and hotglue the plastic case to the metal case? Interweb highfive from me to you!
Can you post pictures of the inside wiring please?
I did. I basically cut out a square from the HD2 back large enough to hold the coiled length of wire that is needed to allow the back to be removed and articulated. Then I used Super Glue to fix the section of the Pre back containing the inductive coil and circuitry to the HD2 back.
If you're trying to maintain your warranty I might suggest DigiKey part number 478-4687-1-ND, it's from the AVX "MOBO Spring Contact Interconnect Solutions" catalog under battery connectors (I can send you a .pdf copy of the catalog, it's too big to upload to forum). This is a 3mm pitch connector that should mate well with the internal connector - but - I don't have calipers so I would measure before ordering. I just soldered the wires to my HD2.
I'll post some pictures soonish.
And yeah, high five for sure. Thanks for pioneering this. My last phone was retired when the power connector became flaky, so it's nice not to have to worry about the contact wearing out.
Ur mod is on a dutch popular website!

Right angle micro-usb
I'm looking to do the same thing with my Vibrant and have been searching for a similar connector. I just did a quick google search and found these angled connectors:

I tried soldering it your way with no sucess
Soldering pins are as shown
(If viewing vertically with top up)
(leftside of hd2) negative x positive (center of hd2)
bumping an old thread to see if you've taken pictures of the contact points yet.
Sorry it took me so long to reply. Two pictures, the first is the terminal with the wires soldered in, the second shows how I got the cables from the Palm coil/board through the cover. The terminals as you look along the longest axis of the phone with the microUSB plug closest to you are GND, something, and +5v.
So from left to right: 1 GND / 2 ? / 3 +5v.
Hi guys, does anyone know the order of the pins under the battery cover for charging? my usb port is very close to death but I don't want to pay to get it fixed when i've got my upgrade in less than a month so I figure i'll just adapt a charger to charge via these.
Same here, bad usb port. I have looked everywhere trying to find out what voltage/polarity to apply to each of the 3 contacts under the battery cover, and even tried applying all possible combinations of polarities to the 3 contacts with a low voltage, all to no avail. My best advice to you, which has worked very well for me, is to buy an external battery charger and an extra battery. I got the battery and charger for 16 usd for both from ebay and they work fine. Good luck to you
someone must know the pinout, I mean the phone is so old someone must have played with it successfully.
Well, you can't just put power to the battery directly, it probebly will explode (Li-ion).
You can buy an external charger (look on ebay or phone shops) or fix the power part of the usb port:

hi,
well i managed to snap my charging port inside my hd2 and well, i get nothing when my charger/usb plugged in... im wondering about directly charging the battery whilst being able to use the phone at the same time... ie having the charger contacts on the phone and battery at the same time... wondering if this is possible as i dont want to damage the battery/device...
also what would i need to hook to each contact? i know positive n negative poles but is what the middle contact??
any help with this would b much aprieciated... thanks
luke
p.s i couldnt see anything that would help me in the other forums i looked at
Yuor best bet is to buy a 2nd battery and a battery charger from ebay then use 1 battery whilst the other charges.
Its not to expensive to repair, if thats the only fault
i see ur from england too so do u know any cheap places that can repair this fault? links if possible... thanks
any joy? I found the following two websites but am now weighing up my options.

I have a similar problem. Don't know how or why but for some reason it suddenly stopped charging on Friday night. £50 to get it fixed is a bit excessive.
I wonder if a battery charger might be a better option?
EDIT: the answer to my own question (so far, at least) is "YES". Bought a cheap charger and battery off ebay and both are working well (touch wood). It's a pain in the butt having to change battery and not being able to charge it in my car but it's also quite useful having 2 batteries.
Hi,
I checked many threads with no solution so this is last chance
Did someone recover the phone from no charging issues ? Even if this is hardware.
I have mine old G1 and wanted to give it a second life. I noticed that it does not charge when off (no led) and when on (led red >orange, status on the phone "charging"). It only charge in fastboot mode (led off). I got new battery, charger etc.
I saw it is common thing but last posts are like from 2010. Does not help: wipe battery, changing radio, battery or charger.
It is 1,6 superD.
Maybe it cost low to repair if it is hardware. How the hell it can be it charge in fastboot?
I would get along with it if it was bricked but in this case - it works but does not work if you know what I mean.
Ciao
try cleaning out the usb port with like a toothpick and some rubbing alcohal, my guess is its hardware and the pins to charge normally are damaged but the pin to work in fastboot mode are still intact. if this is the reason why its bad you would either need to solder a new port to the daughterboard (really tricky unless you are a master @ fine soldering)
or replace the whole daughterboard. which of course is very hard to find by itself. more than likley you will have to by a broken/used phone off ebay (maybe as cheap as 10 bucks) with a working usb but whatever else broken and swap daughterboards, pretty easy to do.
but maybe double check if its firmware/software first by reflashing new rom or doubtfully a new radio/spl

Thanks a lot for the reply.
Indeed buying something with broken screen would do. My soldering capabilities ends on swaping capacitors, far away from micro soldering
Anyway, I tried all other things you have mentioned.
Cheers!
Hi so I bought the device about 3 months ago and it was awesome from the get go everything was great until today when i plugged in my device for charging. After a while i noticed it was charging very slowly so i instinctively disconnected and reconnected the type a usb cable from the charger. On reconnecting there was no indication of charging on my phone. I reconnected it one more time and nothing. So i took out my voltmeter and connected that in series. The moment i connected it it started to restart continuously. On off on off and i had to disconnect it to make it stop. I thought it might be a cable issue so i tried a micro usb cable with an adapter. Same result. Then i switched chargers, again same result. Whenever i disconnected the phone it would stop restarting. On one charger it did stay on but the voltage dropped to 3 volts and amps up to 2.3.
So i have concluded from above stated facts that the charging port/ board is kaput. If anyone has any suggestions on this please let me know.
After this i started to search for a replacement type c charging board for the redmi pro but i cant find any. Any help in finding one with international shipping would be appreciated.
Please leave Ur thoughts on my conclusion.
replace your usb c cable
Thx. But luckily i was able to repair it. Woohoo
Anyone know where to get a replacement usb charging pcb ?
was it a easy fix or did you replace the usb board?

Sorry for the late reply. I searched for the port on various websites when i had the issue but couldnt find anyone who sold redmi pro parts. Luckily however i found a seller on ALIEXPRESS who said that he did have it. He had asked me to pay using mi max charging board which was around 7 usd and then he would send The redmi pro charging board.
Sadly i cant find the seller who said this so i cant share the link here.
What u could do is go on aliexpress, find the largeat stores with the widest variety of xiaomi charging boards and ask them if they have it.

For me it realy was an easy fix and fast one too.
I was out of option at the time so what i thought of was that if i could find a 4 or 5 amp usb brick i could probably melt the shorted portion of the circuit. Ofcourse that in itself is dangerous because it could ruin the phone completely.
Anyways sadly i could not find any such power bricks. When i had almost lost all hope i thought of trying this out in my cars charger because car is already running on a DC system and is capable of providing alot of current to the usb charger, which is just a sort of regulated stepdown transformer. So hopefully that would provide the power i need. I started the car and then connected the phone. The moment i connected the phone to the charger the cars rpm lowered slightly for a second as if it were under stress and then went back to idle. AND MAGIC! It was fixed.
What it did was provide alot of current to the phone which heated and melted the shorted circuit. Since then ive had no issue with the phone.
It might be different for u though so i wouldnt recommend just doing what i did. If u have waranty claim that. If u r out of all options and u feel like ur phone is a dead piece of metal (like i did) then go ahead. But do not hold the phone in ur hand or anything while doing so because it can be dangerous in a number of ways. DC is much more unforgiving then AC.
Hope this helps.
