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 everyone. I've made the error of letting my Wizard get to 0% battery charge... so, when I tried to charge it up, no deal. I read around why, and I understood how this phone charges the battery: ok, no big deal. I followed a couple of posts here, on how to revive the Wizard. I used a 9V battery to let it boot... and it booted! But the battery never kept charge... well, I dunno: the battery status screen showed some percentages, but to be honest it never kept charge, or I had already fried the phone, thus the battery didn't get any charge/the phone couldn't start.
Then I got smarter, I read that a spare battery and the original wall charger would've been better... I took another battery, I attached its 1A wall charger... red blinking led, which sometimes stops blinking.
I fried the mainboard, didn't I ? I'm starting to think that 9V is a lil bit too much.
UPDATE EDIT: Well, I've done some electronic necromancy... the two batteries I had won't charge. I've managed to piggy back them with a power supply, they can boot the phone. Whee. Then I plug in the original wall charger, and... after 5-10 minutes, bang, power goes down. How much voltage do those batteries output after this little trick? 0.00, 0.01. Well, I just bought a new battery... but I still fear I might have fried something. I'm gonna charge one of those old batteries with the power supply and see what happens.
How to Recharge battery. When battery goto 0%
try this.. mine worked. Take a USB Cable cut the small end of the usb cable
not the side that goes to the computer. Strip the wire . all you need is the
red and the black wire. the rest fold it or cut it short. First : take the battery out of the phone. SECOND: Plug the usb to the computer ** becareful don't let the open wire touch each other it will shut your computer down or burn your usb port. THIRD ut the red wire to the + (positive ) and the black wire to the - (negative) on the battery for 1-3 minute. then put the battery back in the phone, turn it on , then plug your charger quickly. Hope this help you..
Thanks for the advice, goon1. I'm going to try this tomorrow, you'll have updates
The battery kept charge for like 10 minutes... then, bam, it's dead. It won't charge with the wall charger, it won't with the usb charger, nothing at all. I hope I just overloaded it and broke when I clumsly tried to reboot my phone, which I'll discover as soon as my new battery will get here from HK
that mean you have a bad battery. MADE IN CHINA. doesn't live up to it name.
the battery from there loose it charge quick. Remember they run 220 and we run 110. Just get a good battery from USA.
Batteries do wear out, and it shows when they wont hold their charge...
Before you conclude your phone is damaged, buy and try a new battery. ;-)
Peter
UPDATE
Since I didn't want to spend too much on a phone I consider bricked, I bought a 3$ battery from HK.
New, supposedly working... the red led is watching me.
Another detail: the power button does not work. In the rare cases where the phone booted, pushing it to go in stand by didn't work.
I'm more and more convinced that I fried something.
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
SOLVED: HTC Wizard (Cingular 8125) Dead Battery Wont Charge

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.
Hey everyone been using this thread for a few months now it's so useful and I appreciate all the help. I know this has been posted before and I tried all the steps listed in the other thread but last night I let my phone die and when I plug it in it just boots up until the dark forces team screen before it starts over again i tried all the steps listed to get it to charge it just seems not to work. I was able to get into the magldr screen if I plug it in and hold volume and power off. From there I choose to power down and as long as it stays plugged in the orange light comes on but when I try to power it on nothing happens. Any advice would be greatly appreciated. Thanks so much
you cant charge it powered off without winmo, simple.
2 options, borrow battery long enough to flash wnmo on your phone, use your phone to charge battery, or put battery in another winmo hd2 to charge enough to start android. (or, let it sit for an hour or two, they sometimes recover a little charge, perhaps enough to boot. Boot with the usb in, cos ability to charge kicks in about half way thru teh boot process.
just to add a third option to my last post, , i let my battery die stupidly today, completely dead, , took an old usb cable, took the end off, black wire to - and red wire to + on battery, plug in usb cable, bite nails and worry for 1 minute, enough charge in battery to power on phone and boot enough for actual charging to start!
phewwwwww.

clever! brave! i like your attitude man
heh, not that brave, i didnt do it till id read about a hundred posts of people doing it on various devices.
@bakse, whats to explain?
get a usb cable,
cut the usb end off,
strip off the silver shielding,
find the red and black wires,
bare the ends,
attach the ends to the battery,, red to +, black to - (it says on the battery which is which)
plug in the usb cable.
After a minute, remove the wires, and try the battery in the phone, and hope it has enough power to start to boot and start to charge.
I read a fair few posts where people were holding the wires to the battery by hand, it is after all only a few volts dc, but i just wasnt that brave and went for gaffer tape.

Ha ha I have been a electrician for 15 years now and I can tell you with 100% assurance that the very small voltage that it takes to charge the battery of any cell phome will never ever affect you in any kind of way. You know I had often wondered if you could charge the battery in this fashion but was not completely sure as my I do not have a full understandimg of yhe iom bstteries yet.

You know I had often wondered if you could charge the battery in this fashion but was not completely sure as my I do not have a full understandimg of yhe iom bstteries yet.

hehe, i did 3 years as an electronics tech in the RAF, (long time ago) so im not usually that nervous around electricity, but i was last night, , generic 3 pin usb charger, generic usb cable, stories of batteries bursting, ANYTHING could have happened!
Ive tried it again today on an old dispensable htc elfin, held it for 5 mins, which is far longer than any posts ive read. Battery got warm, but not worryingly, and when i booted the elfin it had 2%, and managed fully booting plus ten minutes use, and id drained it completely before starting.
Im glad ive tried it, and now i hope i never need to do it again.
I just accidentally let my HD2 drain the battery, but this is the first time it hasn't come on. I did the USB cord trick and it seems to juice the battery, but when I finally got to the menu me being so caught up in the excitement that my phone wasn't bricked and that I could get it running again forgot to plug in my phone to be charged and it died again... Now I am using the hacked up USB cord to charge my battery, but is doesn't seem to charge it very fast and after about 10 minutes of letting it sit I get to the boot screen in Magldr but the battery dies mid boot. Now my question is should I leave the battery to be charged with the red and black wire USB trick and how long can I let the battery charge like that will it be fine for a few hours? Thanks for your replies in advance.

I don't know if it would be safe to leave the wire connected to the battery that long. To be safe I would only leave them connected to the battery for 15 to 20 minutes 30 minutes max. I would also monitor the battery making sure it is not getting warm/hot or that the batterry does not start to swell.As either of this things are signs that you should disconnect the wires.
Well it worked I got it charged to 5% and it took forever, but when I put it in my phone and it booted it said it was currently charging, but when I woke up dead again...
Charge with wall charger, not via PC,, the current of PC charging is way lower, so for an almost flat battery it may not be enough to both charge and run the phone.
Ive been doing this usb cable hack/trick what ever u wanna call it for a few days now my usb port is completely busted and ive got wp7 on it struggling to find anyone near me that will fix it as im not brave enough to take the phone apart and replace the micro usb port
HTC HD2 running NAND won't turn on after battery died
I spent couple hours last night after my phone accidently died and was unable to turn on even charging with wall charger, I read about trick with cutting usb or charging cable and attaching wires to the battery. Finally, I found great solution by myself. I simply connected phone to my car charger and in less than 1 minute it started Android and after couple minutes I was able to move my phone back to the wall charger
actually you can charge the battery with whatever you have handy.
I charged phone batteries with anything ranging from wires cut off from just about any li-ion phone charger (older nokias, samsung and se preferable), solar panels, other batteries (3 standard aaa alkaline batteries in series will do the job also - almost no risk to phone battery) electrochemical reactions (the best one, getting electricity from mustard using copper and zinc electrodes - also worked but you need 6 "custom made" mustard "cells" ), any sort of usb port etc
My choice depended on whatever i had handy at my disposal at that particular moment.
I also powered up phones with empty (or if i suspect them to be dead) batteries by placing 3 aaa rechargeable (ni-cd or ni-mh.. NEVER USE primary-non rechargeable batteries or any sort of alkaline/carbon based chemistry) batteries in series with the + and - leads over the ones in the phone but WITH the original phone battery connected (it won't work if you simply supply the phone with 3.7 - 4.3 volts.. the center phone battery pin is needed).
They all work and for a one time quick emergency charge, it will be fine (just don't make a habit on doing these to often).
Hi everyone,
My Photon Q was probably about 30% charge when I last checked with it on. An hour or 2 later it was a little warm and was off. So I went to charge it using the car charger with 500mah charge rate. I came back about an hour later and the phone was really hot and no charging screen so I unplugged it. The green led light is lit when the phone is plugged in.
I tried holding the power button and volume down button, but it won't boot. If I have the usb charging cable plugged in from a PC or charger adapter when pressing those buttons, the green light will flicker off for a fraction of a second.
I then proceeded to dismantling the phone as I suspect a battery issue and the one in this phone is stupidly non-removable. After taking the back cover off, I tested the battery posts and received 0 volts. I still don't know if the battery caused the drain or if there's a short in the phone. I then took off the inside cover that holds the battery in. A few T5 screws later and the battery was removed. I connected the battery to some AA batteries in series to see if I could get a charge. A few hours later I got it up to 3 volts which held for several hours. So I connected it to a few more AA batteries in series to try and raise the voltage. I got it up to 3.67 volts and the battery is listed at 3.7 volts.
A day later and the voltage is still at 3.67 volts so I put the battery in the phone. I went to try and power it on, but nothing. I then connected it to a usb cord and received the slow flashing red led light a couple times before switching to green. The battery started getting warm again connected to the usb charger. After 20 minutes it was approaching hot so I unplugged the USB. The battery read 3.54 volts. 30 minutes later, 0 volts again.
Does anyone know what the actual voltage range is for this phone, as my old Samsung M320 is also 3.7 volts, but when testing the battery I get 4.10 volts? I heard it's pretty specific on minimum voltage. Any ideas for a temporary battery or way to boot the phone before spending $50 on a replacement battery and then find out there's a short in the phone. Is there another key combination to boot the phone, I'm trying to boot it to at least get my pictures and other data off it.
Thanks a lot in advance
Matt
Not the battery, seems to be an electrical short but where
I bought a new battery for the phone which had a 0 volt charge when I received it. I tried putting it in the phone as is to use the phone charger to charge it, but got nothing. So I charged it using 2, then 3 and then 4 AA batteries in series to get it up to 3.7 volts. I then put the battery in the phone and noticed the 2 large chips and the chip centered above them located by the camera get a little hot. I tried with the charger connected and not connected, but same thing. Power button doesn't turn the phone on. Just the green led lit when the USB power cable is attached. So now it seems there must be a short in the phone. Anyone know where I can look to check for a short, blown resistor or something in this phone? Or at least where the rom chip is located so maybe I can turn it into a usb drive to get my data at the least.
And sorry about the double post. I didn't receive any replies in the other section and I really need to get some data off the phone. Seemed the hardware section would be the place to check. Tree fell on the house and pictures before the tree was removed were taken with the phone which of course ironically stopped working right after.
