Hi guys,
i have a SGH-i780 Smartphone and i am quite happy with it. The only negative aspect is short battery lifetime when beeing always online for push-mail.
Therefore i would like to have a docking station for my device, where i place it and it is been charged. But as the f******g Samsung developers placed the charge/sync connector on the upper right side of the device i would always have to place it in docking and connect charge cable.
Therefore i thought about modifying the phone which means making the 3 battery connectors accessbile from outside to connect the external charger box (including charging electronic!).
And here is my question: do you think connecting a charging electronic directly to the battery while it is inside the phone will harm or destroy parts of the phone? I am wondering whether the internal charging circuit inside the phone will get hurt by connecting another circuit in parallel ...
Thanks for your comments!
For sure this could hurt your device...............
In this case I'd say the risk isn't worth the reward. The risk is that you fry your phone, and at worst it sparks and causes other damage. You can have it check for mail less often, unless you need your email to be live.
such heavy modifications never go without harm to technology.
It simply is not designed to work that way, so you'd be better off with a docking station or a better Powerpack.
You can find those on Ebay for pretty low prices...
thanks for your replies!
I also thought about wiring the +5V and GND pins from the USB connector to the bottom of the device and connect a power supply directly (which but be the way it is thought to be) but the usb connector is very very tiny and i doubt i will be able to connect and solder the cables to the right pins ...
any furhter ideas?
not really no... trying such delicate soldering quests is generally not a good idea without the proper Equipment.
Whatever you do to modify your phone, it will void your warranty and you'll not get a replacement device if you trash yours...
Don't do this!
By bypassing the phone's own charging circuit you are removing any sort of overvolt protection!
Although I am not familiar with this phone and your post is somewhat hard to understand, I take you usually sync it, then take the battery out to charge that separately with another cable?
If that is the case then, no, don't move the connector so you can charge directly to the battery! It will be potentially very bad for the battery and phone.
Out of the question
DO NOT under any circumstances play with your battery.
What you were taught in your physics class do not apply to microelectronics!
There are many 5V+ out there and ALL are different!
While rms value is the same, the waveforms of the current/voltage can be any imagineable. So, the best thing to do near your cradle is to pin a sign "KEEP OUT!"
Technically, you could create another charger that connects directly to the battery. There are dozens of ways.
BUT, since you asked, then you don't understand how. Assuming it is a liPo or LiIon battery, if you charge it wrong, the resulting explosion and fire will be nasty.
Why not get a second battery in an external charger, and just swap them.

I already have another appropriate charger because Samsung ships this phone with an charging box.

Because then i would always have to take a second battery with me, every time! That's awful!
I just want to have a docking station, that charges the phone while it's plugged in ... without terrible wiring needed. Then i can make sure the phone is always fully charged when taking it.
I attached 2 pictures showing you my 2 ideas:
1) wiring the external charger directly to the battery (but of course this would also mean connecting it directly to the internal charging circuit of the phone!). I fear this would damage the phone!
2) wiring the power supply to the power supply connector. This should definitely work, but soldering the cables on the tiny connector will be a pain!
Thanks for your help!
Hi,
That's the first time I am not able to find in this great forum a solution for a problem with one of my 2 wizards (i love this machine...)
Yesterday, one suddenly did not power on. I knew that the battery was pretty low, so I guessed was just discharged. But once I plugged it at home to the wall charger, no amber light appeared, nothing powered on! When I replaced the battery with a fresh one, nothing changed... and when I tried the "bad" battery with my second wizard+wall charger, I confirmed the battery was almost empty (2%), but worked fine.
I tried to plug the mobile to the computer, but nothing... to soft-, hard-resets... the bootloader reset... but my wizard did not respond electrically or electronically to anything... any idea what could be happening? any possible solution? I do not remember exactly which rom I was wearing now, if that matters... probably a FariaWM6_realthing_crossbow
thanks to all in any case
marcos
Maybe out of sight accident
why you leave alone your lovely wizard and so aprecciated mmmm....
its xtrange but as you say i think this kind of forum may helps you with software... took it to a cellphone repair center... they has multimeters to know where does the energy stops... maybe a little electronic component has burn it down. or try the not original and official wall chargers withj specific mhz and amperage, try something more hard.
hope i help you
more news
After being overnight without the battery, this morning I tried a "resurrection"
I just put back the battery, did a softreset, and it worked!... really!? no... just the first two screens (HTC welcome and machine tests) It did not go forward, and a second reset it did not work either... now it's again like yesterday, just dead
I think there is something else than just an electronic problem, but who knows. I recommend you not to let the battery too low!

Charging a completely dead Wizard battery
Delapena,
I've had this problem a bunch of times with my Wizard (Cingular 8125 branded version). I was able to get it working again using the instructions of a VERY helpful person(s) who I want to give credit to but cant remember right now (sorry in advance) so just FYI this works for me, but the credit goes to the original poster (will edit later if I recall).
Easiest method (if available):
1) Locate your STOCK 5vdc/1.0A wall charger.
2) Remove stock battery, put it in a ziplock bag, place in freezer for 5-10 min or so. This should minimize the internal resistance of the battery to boost VDC across the terminals (in case you ran the battery very, very very dead).
3) After the battery is good and cold, put it back in the phone; DO NOT PRESS THE POWER BUTTON!
4) Plug the 5vdc/1.0AMP STOCK WALL CHARGER into the phone.
5) Charging indicator (solid amber LED) should light up after 5-10 seconds with no other indications (no screen, no beeps, just solid amber LED ON).
It's my understanding (may be wrong) that the 1.0amp wall charger uses/supplies 5vdc one one or more of the mini-usb plug pins than the standard USB->mini-usb cable used for standard data-transfer on standard USB-spec devices. Also, the wall charger sources a full AMP of current at 5vdc, as opposed to the 0.5amp each USB host IC is allowed to source (e.g. the USB host IC on your motherboard/front/back of computerbox).
...reply to this if you want the comprehensive method. Ill research if above doesnt work / you dont have the charger. Swamped at present though; if you need the full blown recharge-the-battery-from-the-stoneage method ill look it up---dont want to give you invalid info.
If you dont want to wait (i'd understand, been there), try searching around a bit if you havent already found what your looking for.
Reply back if you need more help, otherwise, good luck and replace your battery with a new one asap!
Cheers
(again, no credit to me on this one, got this solution from somewhere else on the forum a long while back...credit to original poster!!)
Sir,
I didnt read what you had already tried. My wizard is rebooting constantly as well. My thought is that my battery is so old that the battery charging chemistry is so out of whack that the battery charging / voltage sensing circuit is all sorts of confused as to where the (really old worn out) battery is on its charging curve.
I'm guessing that my phone is rebooting because the battery fails to supply adequate voltage at x.xx amps of current draw to the phone's internal voltage regulator. When the IVR cuts out, the phone poops its pants.
I'm currently looking for a battery replacement myself.
more... but less
Thanks for the help, brhestir. But did not work for me. Actually, I tried with the 3 batteries I have, which actually work OK in my second wizard.
The only thing I am able to "slighlty" reproduce till now:
1) Wizard remains several hours with any battery plugged
2) I put the battery back
3) I switch it on or do any kind of reset
4) Just sometimes, the machine starts up, but gets hanged up after the first screens
5) most of the times, after this... the screen turns white slowwwwly, till it switches off
6) only once, I managed to get the bootloader screen, which stayed like that with any problems... but the computer cannot connect to it, so impossible to change the rom.
Next step: to dismantle the machine (prior step before throwing it through the window)

wow i just ran into the same problem today.. my battery was low tried to plug into the cigar lighter but the fuse was blown due to another object i had plugged in so i didn't get a chance to charge it, the phone was fine all day until i left work it was completely dead.. no amber light for the charger.. have you had any luck?
hi everyone,
i solved this problem by creating a sort of bypass for the battery...
i bought a special battery used for some circuits experiments which is 4,5v..
i connected the + and - with the phone contacts, with the battery plugged...turn on the phone until the orange light is on and leave it until charge is full...
this is cause phone needs a minimum of charge to start recharge circuit...
Yes the same problem on every post
The thing of cooling batteries is an old but knowledge charging fast option but it brokes your performance batt drain so i recomend a new full battery ok? is the only way or...... charge the one you have fully fully.
and try again! tu plugin the batt once at time and again and again it wouldnt boot cause its too low to begin the OS and let you charge with the wallcharger... to charge with the wall or usb you need a bootable and functional OS ok?
hope you can find a way to charge your batt at least sufficient to boot the OS ok?
bye
well good news! 20 minutes in the freezer + 5v + 1a = win
CONGRATS!!!!!!!!!!!!!!!!!!!!!

lol it was an accident i thought it was charging in the car!
Hi all, for those of you that have experienced a totally dead battery you'll know the pain it is to get it going again. I have recently had this happen and decided to post a fix on here.
Lesson #1 Dont let your battery die completely, if you get a low battery alarm, turn your phone right off till you can charge it.
Lesson #2 If your battery dies completely, just throwing it on the charger wont charge it. This is because the Operating System looks after the charging. If your OS wont load, your battery wont charge.
FIX:
After trying various methods on the net, I found a surefire way to jump start your Wizard so you can get it charging.
You'll need : 3 x AAA batteries and 2 lengths of wire and some tape.
I cheated here, I managed to pull a 3 pack AAA battery setup out of a regular Panasonic cordless phone which saved me having to piggy back the batteries.
1) If you dont have a battery pack, you'll need to piggy back the batteries. + to minus on each one so that you have 3 batteries connected to each other with one free + and - side. Use the tape to keep the wires from moving around and getting loose.
2) Remove the battery from the phone.
3) Put a wire from the + side to the top connector of the phone battery connection ( top gold pin, right hand side of phone nearest to the power button )
4) Put the other wire from the - side to the bottom connector of the phone battery connection ( bottom gold pin, right hand side of phone nearest to the camera button )
*** There are 6 gold connections sticking out on the side. Make sure the wires only touch the top and bottom pins. Bend them round if you have to and clip them if needed.
5) Try the phone and it should switch on now. If it does, push the battery back into place while its loading.
6) As soon as you get to the today screen, plug your charger in. Wait about 1 minute and check its charging ( from the battery icon under seconds ).
7) If its charging remove the wires from the AAA battery combo ( in case they explode or something ).
Hope this helps the next poor soul that didnt have time to charge their battery before it died completely. And thanks to all the posters that have helped me out with my problems. Long live the Wizard
While this is a good post, it in not entirely true. If your battery completly dies, you can infact use a standard wall charger that outputs 1AMP or more of power to charge it with, even if you phone wont start. The charger that is included with all HTC devices outputs 1AMP, so they should all be useable. Good post otherwise though!
Thanks ashasaur. When I posted this I did not have access to a standard wall charger. However looking at getting one just in case this happens to me again. HA I hope not.
Thanks for all that advice. In desperation, I have just bought a new battery and was relieved to see my Prophet come back to life, having, yes, let the battery run completely down. (I am away from home, where I left my charger as the Prophet seemed to charge quite happily from a USB port)
If 3 AAA batteries work ok (~4.5 volts), wouldn't it be a bit safer just to connect them to the dead battery for a while, as described above, to give it a bit of a charge, rather than risk the phone, or isn't 4.5 volts enough? Greg
buy a 4.5v 500ma adaptor and it will work
Earlier I was afraid of dead battery and use to turn off my kjam but later I got an idea and purchased one 4.5 v 500 ma wall adaptor($1 only) and cut the end socket and use it to give initial charge.
Earlier I was so much worried about my battery that had to put it in charging point where ever I find a usb port but now seems Kjam battery knows that's why haven't died for 2-3 months even though sometimes I forgot to charge it in night

Great idea. Just tried it with an in-car USB power adaptor, but it didn't supply enough oomph. If you follow pawanmehta's advice, you might want to check out this site - USB pin out and lead details - for the correct leads to wire up.
A quick look around the internet suggests that mains to USB power adaptors are available at £4.85 (UK) or $15 USA but I expect a proper search would turn up cheaper items. Greg
It works with a O2 XDA Mini S, but it didnt work at first time: I have to put the cable with the 3-battery-arrangement and the 3.7 1400mAh battery at the same time, it's looks like that it wont turn on if the pins are not pressed, but well, I succesfully boot and now i'm charging (i remove the 3 battery arrangement).
And, I use 3 AA Duracell batteries, I tought it's the same than using 3 AAA, 'cause they use the same voltage (1.5 for common, and 1.2 for rechargeable).
Best regards, and thanks a lot MattyZee, u have my blessings

hey everybody...
i read the thread a few days ago and thought...okay good to know but that will never happen to me now that i know that it shouldnt...
now...a few days later...of course it happenend...
soo...i tried everything. but the things are complecated to do alone...with all the wires and then pushing the power button and installing the battery again...
so i had to give up...
but here is another way how to do it...
it is already beein mentioned i think...
use the 3 battery combo, 2 wires at both ends, take out the dead battery and put the - wire to the pin at the very botton (the bin at the longer end) and the + at the other end.
hold that just for about a minute (i think i just holded it for 10 seconds but a minute would be better maybe...)
and then put the battery back in and it should start...
oh and i tried to use a 1400mA wall adapter and it didnt worked...
but try to avoid that...
it is not a nice situation seeing youre wizard dieing like that...
and at first i thought it is not the battery...i thought it is broken...
so avoid it if possible...
thats it...
What is length wire (sorry if it's a idiotic question)
please help
btw, I have O2 xda mini S.
And can I use 3 AA batteries????
thanks a lot,it worked
once again THANK YOU
You guys are geniusses It started, but when it started I put the charger in it fro my laptop and waited a while (removed batteries) then i saw it was charging but when I was waiting some more it yust fell off !! So i started it up again with the AAA's and then putted charger back in and i was using the phone, I saw it was charging and I looked @ lvl and it kept on saying it was on 0 % :s Then i thought let me wait a while and i stopped using it so it fell off again, what did I do wrong twice ?
Thx
A 9v Battery (The type you find in smoke alarms) does the job as well.
ONLY connect it for a couple of seconds, but repeat about 5 times then connect it upto a usb data lead and after about 10 seconds it should kick in.
After its been charging for about 30 mins turn the Wizard on.
Have succesfully used this method on 3 Wizards now and it works every time!
Don't Forget To Put The Battery Back In Your Smoke Alarm!
Exceptional
Thank you. I have a Kaiser that I love, and was just handed a Wizard that wouldn't even start. This post let me boot it and start the charge.
Thanks.
Apologies for bumping an old(ish) thread but I've tried this jump start method and seem to be having no luck with it.
I've tried the methods suggested, using 3 AAA batteries didn't seem to do a thing for me, but I've had a slight result using one of those square 9V batteries; the camera flash comes on and the screen lights up but wm doesn't begin booting up (the screen just stays blank but lit).
I've also tried attempting to give the battery some charge using the method mentioned earlier but that too doesn't seem to be working either.
The battery in question is brand new (one of those extended ones with a higher mAh) and I'm assuming it's arrived with zero charge in it.
Does anyone have any suggestions?
(incase anybody is wondering, the wizard boots up fine using a different battery which is charged)
edit: if it's of any relevance, the wizard's a g4.
edit2: I've tried charging it with the wall charger but all that seems to happen is a red light flashes once every 5/10 seconds and the screen flickers on then off
Update: After numerous attempts at jump starting, my wizard now refuses to charge whatsoever.
The light flashes orange (I did follow the guide posted on the wiki about that but it had no effect) but it comes up saying it's charging onscreen, however it simply doesn't charge (the battery life just slowly drops).
It's the same using either the wall charger or usb.
I did try taking the battery out/doing a soft reset/doing a hard rest but to no avail.
Would I be correct in assuming my wizard's now broken?
I'd just donated my blueangel to a friend too as I thought I'd no longer need it, but now i'm left without a phone
I've found a standalone battery charger on the internet for around £10 or so, I might give that a try. If it works, I'll have my wizard back, albeit without being able to charge it while it's switched on. On the plus side, it would eliminate the need to jump start it ever again though.
wizard resurrection...
This problem is quite a hard time for the wizard users...
I know many users with 2 or 3 wizards in the closet because they just died, and there are none powered batterys around...
I hope this can help someone, somehow...
WIZARD RESURRECTION
Props to all!
undertuga
How did u make out with the battery issue? I have the same prob and the light on the camera lights up but i can't get it to charge and i'm using a new battery any suggestions would be helpful. Thanks
Just to repeat a comment made by ashasaur 12 months ago. You need a 1amp charger. Although someone had success with a 500mA charger, that wouldn't work for me, whilst a 1000mA (1Amp) charger worked to recover a completely discharged battery.
A new battery should not have zero charge. NiMH batteries do not like being left around fully discharged and, to the best of my knowledge, are not supplied discharged.
hi there.
shortly-i have this phone with no orig. usb cable and with no wall charger. it was friend of mine phone actualy. given to me with dead battery (i am not sure but i have trouwn it away long time ago)
first I did was to wait until friends of mine from china had sent to me 2 batteries compitable with the phone. what i discovered is that a normal ordinar usb cable cant charge the phone's battery it only can connect to the pc.
second what i did is this: i found my old charger from a very old panasonic cell phone and had a try to make the charging process with the simply contacting corresponding pinouts of the battery to the +&- of this same charger (somehow i dissasembled the plug of that charger and it became more "comfortable" to get in touch to the pinouts of the specific cingular's battery)
that unordinar way i did discovered that i can charge these batteries even not sure how much appropriate that other brand wall charger is. It seems its pretty much the same as a power characteristics.
Meanwhile (as i dont use this phone) i had some free time to search the net and to have better idea about that strange unordinar power charging matter with that model of a phone. The situation is that i cant find a place nearby me to buy a cheap usb and wall charger and become using this nice device finaly.
And also i dont want to buy these cable things before clearly understand why this happens ..
I did try also to charge this phone with a HTC brand wall charger but no sucsess again cause it seems this wall charger is for other htc phone (even same mini usb plug and same characteristics)
What i need is to have answers by someone very informed about that matter and let me know what exactly is the specific power charging matter (need explanations i mean) with this phone. If sharing some good ideas about how to remake others usb cable or wall charger for geting it work along for me in such a case , i will appreciate this very much
thanks
charge
hi ! please forgive me for my bad english! in this case you can charge your phone in 1 way! you need to procure a motorola or any charger with same socket but attention the charger must have 6 volts and no less than 500 mAh(milli amps)! you cut the wires and one wire put on the + of the battery you will see the signs on the battery an one wire at the - no matter which one. and you need stay with the wires 3 - 4 minutes on the battery ! then you put the battery on the phone it will start and then you cand fully charge it with the usb cable ! good luckk ! i hope my inf will help you!
no
no it doesnt work that way.
what i need is the simple answer : what is so special into the pinouts of htc cingular 8125 wall charger?
thats what i need only. Then I might figure out how to proceed
Thanks anyway
I don't know if anyone else has had trouble doing what I have done, but I've got the Cingular 8125 (HTC Wizard 100), which is also known as the HTC 8125.
1. I bought a car charger at a convenience store for $6 that had the mini-USB plug. It worked like a charm. Never any problem there.
2. I also bought a standard USB to mini-USB cable from the local computer store, because I had lost mine, and it also worked fine for both synchronization and for charging.
3. I bought a second wall charger, buying a standard mini-USB wall charger sold pretty much everywhere cellular phone chargers are sold. It's a common charging port, and this generic worked for me as well.
I'd be interested to hear if anyone has had problems with these types of devices not properly charging the unit.
Even my USB cable for my portable USB hard drive will power my unit.
EDIT: About your problem with it not charging. I had that problem about a year ago, when my battery got extremely old. It wouldn't charge even with the original charger. I just needed a new battery. The batteries get old and stop taking a charge after a certain amount of use. How long this takes depends on how heavily the batteries are used. They, like car batteries, do not last forever.
I had this problem when I had my wiz too. The battery died and drained, and my phone refused to charge it. I took it to an AT&T service center, and they had no clue what the problem was, and they wanted to issue me a replacement (it was a G4, I had a G3, I wasn't about to fiddle with that at the time.) So I asked to borrow a demo device they had there to fix it. I charged my battery on their demo device no problem, got it up to 3%, and finished charging it through my USB cable in the car socket.
It appears to be a sort of one-in-every-few-or-so type condition, but I got hit with it.
seems like noone can tell me if something special inside the mini-USB plug.
i realy cant charge. Very nice device, but i cant make it charging up whit cables.
guys, from up there, say that nothing special about the charging cables, but i trust what i see not what i read.
Perhaps there is a problem with your USB port on the device? USB charging has standards, and all devices that need power from a USB port have the same power pin configuration. Otherwise, they can't call it a USB connection. It would have to be called a proprietary connection, and they would have to change the plug size/dimensions and pins.
If there isn't a problem with your battery (which is the most likely source of your problem), then it may be a loose connection on your USB connector. This happens with a number of devices.
If a sync cable connects to the PC but will not charge the battery, then you definitely have an unusual pin detachment of some sort, or a bad battery.
thanks again..
for pity i was writing a lot to make my recent post and finaly it desapeared cause my session was left.. its funny in some case, but now i just dont want to repeat all what was intended to be posted
i give only the link where you might see why i was assuming that this is a kind of a special matter here with that htc 8125 charging
//pinouts.ru/CellularPhones-A-N/razrv3_charger_pinout.shtml
so, any more help will be appreciated a lot
thanks

Hi - Too bad for the OP that asked questions but did not listen to this brilliant post.
I have confirmed that a variation of this method works perfectly! I have an old Cingular 8125 that I have been trying to charge for over a year using various USB chargers and NONE would charge the device.
The reason that this may happen is that the original charger has an output of 1 full amp which is much higher than most chargers. The voltage is the same but you need a charger that can handle such a strong current draw.
Nearly all USB chargers can only handle around 250milliamps - 500milliamps which is about half the power needed to breathe life into a fully discharged battery.
The best solution is to NEVER let the battery fully discharge.
Here are the details of what I did:
1. Find the best match charger of 5-6 DC Volts and ability to put out as close to one amp (1000mA) as possible. I chose an old Sanyo SCP-07ADT that is rated at DC 5.4V at 800mA. The plug can be any type, no need to be USB.
2. Cut the connector off the end of the cable and strip the outer black part up about an inch and then strip the positive and negative (red / black respectively) wires up about a millimeter, just enough to have bare metal ends to touch to a small area.
3. Take your battery out of the phone, look at the back of battery for the + and - marks which correlate to one of the metal connection points on your battery, this is where you will "touch" or "attach" the bare ends of the wires.
4. Plug the charger in making sure not to short your bare leads. Before you do this double check that the OUTPUT of your charger is indeed DC voltage so that you don't hurt yourself. You do not want AC output and it can be dangerous.
Then touch the bare end of the red wire to positive of battery, and black wire to negative terminal of your battery. I held them with my fingers while surfing the web for about five or ten minutes. I had no idea if anything was happening or not but it "felt" like the battery might have gotten just a bit warmer.
5. Unplug the home-made bare wire charger and put battery in your phone. Quickly attach a USB charger or just plug into a USB cable of your computer. I pushed it in and nothing happened at first but finally I heard the standard "bleep" when you plug a USB device in. I knew that I made progress because it never beeped before it took about 30 seconds and several "bleeps" of connecting/disconnecting from USB but eventually the charge light stayed on!
It's been about 30 minutes and I'm up to about 50% charge and been using the phone heavily while charging.
So, in summary... never let your battery discharge below 5% or you can only charge it with an OEM cable rated at 1amp (rare). IF you let it discharge to "dead" then charge for 5-10 minutes with the "wire" method and then charge normally!
Thanks to Dozzen for the original idea!!
Wizard that won't charge
When my Wizard/HTC 8125 goes dead my cure for the battery is to use a 9 volt charger with the wires stripped back also. But, my method is a bit different. I place a standard Christmas Tree light bulb (the newer small ones)in series with the charger wires. Observe the correct polarity. The battery is labeled + and - so that part is easy. By using the small light bulb you are doing 2 things. 1.You can see the slight glow from the bulb and know that proper connection is made. 2. You are limiting the charging current to the battery.
If you get really creative like I did you can solder a couple of small nails or in my case a set of red and black probes to the setup and the points on these nails/probes make for much easier connections. Note.... This method may take a few minutes longer but, is much easier on the battery.
In my experience once the battery is below a certain level NO charger that I plug in will work. I just purchased a used 8125 from eBay and brought it back to life most successfully with this method.
hy there my htc wizard battery whos dead so i charched with a cable with + and - the phone starts but when i try to connect to a usb or a adaptor it doesnt charge anymore it show me the charge icon on the baterry but it doesnt charge the usb works fine it's sync to my pc but it doesnt charge anymore... what sould i do?
So it seems no one touched on what really matters here.
A design flaw, in my opinion. The HTC Wizard cannot recharge via USB unless there is enough power to turn on. The reason is because it requires the OS to charge.
So, what many people already posted are very creative ways to charge your 8125. The easiest and cheapest way, in my opinion, is to use AA batteries.
1) Take two AA batteries and tape together so they are in series. Imagine it like this... [- AA battery #1 +][- AA battery #2 +]
2) Use two wires and tape one to each side of the AA's (one on the + side and another on the other battery's - side since the - of the first battery is connected to the + of the second).
--w-i-r-e--[- AA battery #1 +][- AA battery #2 +]--w-i-r-e--
3) Connect the positive (+) wire to the positive (+) side of the phone. By this I mean the 6 metal pieces that stick out to contact the phone battery. I did it by wrapping the wire around the top most one (or second top most, it's been over a year since I've done this.).
4) Connect the negative (-) wire to the negative (-) side of the phone. Again, bottom most or second bottom most (see #3).
5) Insert phone battery while the wires are still in and connected to the two AAs.
6) Let the power flow for 30 seconds or so and then try turning your phone on. This part is the important part because you cannot use a USB to mini-USB connected to your computer to charge the phone unless the operating system can function. Meaning, it needs to be turned on first.
7) Once the phone is on, plug in the mini-USB part and connect it to a computer. I'd recommend getting at least 5% battery before disconnecting the AAs, seeing as you need to be able to start up your phone long enough for the OS to boot. Once the OS boots, you can fully charge it through a normal USB to mini-USB connection on any computer.
old post but just wanted to say thanks. Used the wire to battery method and got phone turned on after 2 mins of holding wires to battery.
Hi guys, in need of a bit of help here.
right, having not realised what i had done, i pulled the battery whilst on charge before i pulled the charger. my current situation is that now the phone is stuck on the loading bit. the version of android i have comes up with "droid" then goes to a red eye like thingy whilst loading. it keeps looping that screen over and over.
after a quick search i saw my problem could have been bent battery connector pins, but alas they are fine.
after another search i reasised what i had done (or at least what i think i have done). would i be right in thinking that the battery now does not have enough power to boot android and get to a point where it can charge the battery?
having seen the threads on here about using a USB lead to manually charge the battery i am at my wits end. i tried the USB fix and it didnt work.
i have now found this thread: http://forum.xda-developers.com/showthread.php?t=978101
and am currently attempting to charge my phone using the "USB mass storage" setting on MAGLDR (v1.13 btw) but the bit that im wondering is the bit that says "you will NOT get a charging indicator in this mode"
does any one know for sure whether this is true? i am hoping that the thread is correct my only doubt has arisen due to the fact that the thread was based on a HD2 running WP7.
thanks in advance for any help

Try to measure voltage at pin +/- on battery. If there is more than 3,6V battery is able to boot up the phone if voltage is belov 3V it's bad. If You have an adjustable (for laboratory use) voltage source, connect it to pins of phone vhere normally must be connected +/- leads of battery (carefully check polarity), give it 3,7V and try to load the bootloaderon the phone (hold Vol.Down butt and power button together). If it doesn't work, you may have ruined the bootloader.
I read some of the thread you linked. There is something that I think the OP of that thread and a whole lot of people using MAGLDR do not understand. I qoute this straight from the OP of the MAGLDR thread.
*Fixed Power-Off-Cable-Plug-Stop. Phone now detects this situation and reboots. Battery controller inside LEO needs runtime control during charge, it implemented in OS.

You have to have a functional OS installed for you to even be able to charge your battery using your HD2 when you have MAGLDR installed on your HD2. The simple fact that the OP of that thred has a WP7 ROM installed on their HD2 is the only reason option #4 USB Mass Stg even will slightly charge the battery, if it was no ROM on the phone, just MAGLDR, it will not charge at all just as when you are in bootloader and the USB connected it will not charge no matter if you have a ROM on the phone or not. I personally think the slight charge you get by using option #4 USB Mass Stg in MAGLDR is purely accidental and only a small amount of voltage as it takes so long to get any kind of substantial charge. Also if you have a completly dead battery you can not even boot into MAGLDR to try to charge using opyion #4 of MAGLDR.
I am a electrician and have been for a little over 15 years and in my oppinion if you have a dead battery and you are running Android from NAND or a WP7 ROM using MAGLDR. Your best bet is to use.
A: A external charging cradle.
B: Another HD2 that is running Win Mo.
C: Using a modified USN cable to get enough charge to boot into your ROM
Note: The last option I listed is only in a emergency situation as I do not advice you use this as a everyday charging technic. Also only long enough to boot your phone so you can finish charging normally. If you do use this option maintain a constant watch of the battery to insure it does not start to become warm, and only use your wall charger when using this method. The voltage is very low that the wall charger sends though the witres so there is no danger of shock.
Do You mean that when HD2 is POWER OFF state it doesn't charge battery? Even from wall charger? Mine does charging pretty well when turned OFF...
All phones I repaired or dizassembled had hardware automatic for charging battery, not depending of ROM or OS at all, it must have only 5V at charger inlet (USB or dedicated charger port i.e. for NOKIA), I doubt if HTC gone other way that all other developers

Yes a HD2 can charge in a powered off state if you are still running a Windows Mobile ROM on it. If you have flashed MAGLDR to your HD2 you will not be able to charge your HD2 until you flash a Android or WP7 ROM to it as the charging is to quote the OP of the MAGLDR thread again, "Battery controller inside LEO needs runtime control during charge, it implemented in OS."
As for as a schematic no real need for a schematic. You take and cut the end off of a USB cable, the end you leave on needs to bt a standard USB male end. Next you strip back the outer insulation and the inner foil layer, then strip a little off the ends of the black and red wires. Finally connect the red wire to the positive terminal of the battery (marked on the battery), and connect the black wire to the negative terminal on the battery (marked on battery) and plug the USB male end of the cable into your wall charger, not any other power source. Yopui can use some tape to keep the ends connected to the battery.

You tried this even one time???
NEVER DO THAT, YOU WILL RUIN YOUR Li-ION BATTERY!!!!
Li-ION charges at no more that 4,2V, internal protection circuit will shut it off if you get it to 5V charger directly and if this protection accidentally will not work your battery blows up! 5V must be applied to USB port ONLY if you want your battery and phone alive
unfortunately i dont have a way of measuring the voltage of the battery, i have now just bitten the bullet and ordered another battery and an external charger. that way if the battery i have now is dead i have a replacment and if it just needs charging then ill have two batteries. having tried the USB cable charging bodge and it not work im thinking i have killed the battery. i use LiPo batteries in my airsoft stuff so i know that they can die if not treated properly. my own silly fault i guess haha.
ill update tomorrow once the charger and battery have arrived.
what do you guys think will be wrong with it if a new full charged battery doesnt work?

If your new battery wont work than you probably may have a dead charging circuitry on your mainboard (sudden death when removing a battery during charging process) and if that circuit works only under OS control, IMHO your mainboard is useless too. Have to be replaced or repaired.
fair enough, thanks mate. fingers crossed for tomorrow the hehe

I have not personally tried charging a my battery this way bit I know several people on her that have and it does charge the battery. If it did not work for the OP of this thread than they either did not have a good connection between the wires or the battery is not chargeable anymore.
Look at your wall charger it should say on your wall charger that the output is 5.0 v or 5.1 v. This is pretty much a standard on all wall chargers for phones as they all require the same voltage. Yes there is a protection system that monitors the charging voltage and if you use the modified cable to charge you do not have this protection system. But your wall charger unless the small transformer in the actual plug part that is the charger malfunctions will only put out 5v, actually it will probably be more like 3.5v as the 5v is Max output capacity. Also if the transformer malfunctions it is just going to melt down and not put out a charge what so ever, it will not cause a spike in voltage. Trust me on this one, my job requers I have a full understanding of transformers be it a big one are a little one as I have to work with them all of the time. But I did put my warning in there for a reason as this can kill the battery where it can no longer charge, and even though it is menamal it is a small risk of the battery exploding, but it is a very small risk.

Just for info I've done this twice, once thru wall once thru usb slot. It only needs about 45 seconds to get enough charge to start booting, and charging starts about halfway through the boot.
you are right that it isn't recommended, of course, but then most of what goes on on this site isn't recommended for a healthy phone

Man, I do not intend to start a holy-war about it
It's a little off-topic, but seems that you do not have idea how these power stage of mobile devises works (from wall outlet to battery), all mobile devices are very similar in this aspect, simply google what is Li-Ion battery advisor, how it works and rules of charging Li-ion batteries, there are a huge bunch of forums specially dedicated to this theme...

Ok first of I am not madd by no means, and no it is not off topic as people need to be able to know these things. As I have seen in a couple of XDA members signatures "I am learning from you, and you are learning from me."
I Googled the Li-Ion battery advisor and found the PDF I think you were talking about as it was the first two links Google pulled up. But I have to tell you what is discussed in that PDF is on Li-ion batteries for vehicles not cell phones. Those batteries are much large and there for data in that PDF can not necessarily by applied to cell phone LI-ion batteries, unless you care to educate me further.
Like I said I have been a electrician for going on 15 years now, I know how to read electrical schematics, I know how electricity flows, I know about positive and negative charges, I know a lot I will just put it that way. If you have further links YOU would like me to check out I will be glad to. But from my prospective what I mentioned as a emergency charging method is no more dangerous than shaving with a disposable razor.
right so the new battery doesnt work, charged it in the external charger and nothing. same as before just looping on the Droid boot up screen.
would it be worth flashing back to WM6.5 as a last resort?

Any photos of boot screen?
Try to flash back to older official WM ROM with regular SPL (flash from SD card not thru PC sink), else HSPL and that custom bot manager wont be erased from NAND. May be it will help You, I used this method when my touch stopped responding and it was a solution for me.

You are correct to tell the OP to flash via SD card or they would still have HSPL. but the custum boot manager as you called it is actually a custom bootloader. And if you flash a Windows Mobile ROM be it custom or official through RUU or SD card it is gone. MAGLDR or cLK bootloader run in sesession of the original bootloader meanning you never lose the original boot loader( if you did you would have a bricked phone) and that it is not in the same partition of the NAND memory as the original bootloader. MAGLDR, CLK, AND CWM are in the same partition as the OS, therefore when you flash back to a Win Mo ROM you lose them.
HSPL would not have anything to do with the OP's problem as it is part of the original bootloader and the two main purposes for HSPL is to one beablecto flash a official ROM that is not meant for your HD2 without having to use a gold card, and to disable the CID check so you can flash custom firmware.
At the OP have you had a look at your battery pins to make sure they are all in properly aligned with each other and that one is not bent?
