Battery Charging Problem

If I let the battery on my Wizard run down completely, I can't get it to recharge, either with a wall charger or USB charge/sync cable. I have to replace the battery. Is there a way to jump-start the charging process?
After I put in the new battery I can't even get the Wizard to boot up. I have to reflash with the provider ROM and then flash with my desired ROM. I know I shouldn't let the battery run down, but I have several Wizards that I alternately use, and unused, the battery runs down and then the Wizard won't restart and the battery won't recharge.

Been there!
I solved this problem by buying an extra battery, which I keep with me, fully charged in my laptop case. As far as the wizard goes, it will only charge the battery if the operating system is booted and operational. I was lucky to find a site with a whole group of people who had the same problem and came up with a solution that is crude, but it works. Take a usb to mini usb cable and cut the mini end off. Strip the black and red wires, plug it into your laptop or desktop usb port and touch the black to the negative terminal of your battery and the red to the positive. Hold them in place for about 20-30 seconds, place the battery back in the phone and it should boot and then charge normally. Somewhere on this site you will find this information and a couple of posts from people who used basically the same tehnique with a nine volt battery. I can tell you the usb cable trick works, but I haven,t tried the battery approach.
Good Luck!

Internal battery is very low!!! Need Help

Hi,
My wizard main battery (wiza16) was very low and the wizard stop with a message “The internal battery is very low”. After coming back home I have tried to charge but it is not taking charge and didn’t turn on anymore. I recently bought a new battery (wiza16, 3.7 VDC, 1250 mAH) thinking that it will work again but still the same problem, wizard is not taking charge or turn on.
Can anyone help me?? What can I do to start my wizard? Do I need to change the tiny little battery (which is inside the wizard)? Kindly help me.

Wizard service manual
Hi,
See if when you connect the power plug the led turns red, if yes....
If Charge light is red when plug in AC adapter, it means the main battery is not charge enough and can’t power on,
You just need to continue charge unit the light become Amber
If not, i think you have a problem.
Check if charger its working and if its pluged.

Wizard Battery discharge completely
Hi,
Thanks for quick reply. there is no light when i connect my wizard with PC. I don't have the AC charger, I have lost that for long and was using my PC usb to charge. trying to get one AC charger.
There was no problem with my wizard, just can't turn on after it's battery discharge completely. Even the new battery couldn't turn that on.

You'll need the original charger if the battery has complelty discharged as it will only charge from the computer if the phone is powered on.
This happened to me before.
There is a trick to giving the battery a quick charge which will give it enough juice to boot the phone up and allow it to charge from usb. its not recommended but works.
You will need a spare usb cable, cut one end of, strip the wires back and connect the red wire to + and the black to - on the battery, only do it for a short period, about 30 seconds while conneted to your computer.
You may need to give it a few 30 second bursts to give it enough juice.
Pop the battery back into the phone and switch it on while pugged into the PC
Took me a few attempts to get enough charge in the battery for it to boot up.

Wizard battery
You can also use a 9V battery to jumpstart your battery. But then you have to be more careful. I connected the 9v battery to my Wizard battery for about 15 seconds, then tried to start up my device. If not successful I started again with 15 seconds jumpstart..
But you can find more information here in the forum: just search for jumpstart or something similar....
Regards
huibuh_!

Wizard Battery discharge completely
Thank you all for information. 9V battery method didn't work for me. Looking for AC charger online and get a link (http://www2.dustin.se/pd_5010073700.aspx). Do you think this is the right one? If yes, then I can order.

yea that's the right one but if you have a friend with a ppc or maybe a razor you can use there charger most ac adapters are starting to use mini usb just a way of saving some money even though having an ac adapter is good
could also try and get one of those usb plugs that you can plug up to a wall and plug in a usb cable into the slot
but don't take my word for this wit hmy wizard i haven't had it shut all the way day
if anybody can verify this would work

AC charger not also working
I have got the AC charger yesterday. When Connect the Ac charger first time the red light on my wizard showed for just half second then dissappear. Still let that connected for whole night but no response.
Thank you all for help.

@Keland44, most Razr chargers dont work, they MUST be at least 850mA in order for the Wizard's battery to receive anything. The older Razr chargers are sometimes as low as 350mA, but the never ones are as high as 1.2A, so you need to read the label on the charger itself to be sure.

Yup that is about right,
If the battery is complelty dead, then you need to original charger.
If you have got the right charger and you get a red light and it goes off. your phone might have a problem.
This happened to my last wizard after stupidly trying to dry out the screen after getting it wet which stopped the touchscreen working (i was drying it out while the phone was still on) well my wizard crashed.
Took ages to get it back on but it was very unreliable then one day, it wouldnt go on and charger done nothing. Unpluging and pluging the charger in several times got a red light on.
Sometimes i could get it to turn on, the charger would charge for about 5 minutes then the phone would die soon after.
Your phone might possibly be bricked.

[Q] MAGLDR 1.13 battery wont charge unique

So I have read about MAGLDR 1.13 battery drain fix "*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." and Yes that works fine! However once im in my OS Hyperdroid, my battery dies instantly and my phone turns off and turns back on thanks to MAGLDR then repeats until I unplug my charger.
Why wont my battery charge once im in the OS
Side note - I have taken the batery out and charged it via USB Red on + and Black on - If i charge it for 30 sec it will boot to OS and have 0% once i stick the charger in it dies instantly and reboots
Side note 2 - "" If I charge for over a min via Red/Black +/- it will boot into os and give me a inaccurate battery reading of 60-65% and will not charge once I insert the charger.
Can anybody help?

It looks, you may have to charge battery a little bit in Bootloader screen before you can turn in to OS.

I think something might be wrong with your cable or charger. When you charge, do you get over 800ma or similar? Use current widget to check.
$1 gets you a reply

Have the charger plugged in all the time, and charging should start long before the rom finishes booting. The also, do use the wall charger, and not the pc's usb slot, which may connect and disconnect the time or two during boot, and stopping charging.

Thanks guys I have used 2 different chargers and it doesnt seem to be the case, im going to chop this up as I need a new battery, when i charge it manually via Red/Black to +/- for over 30sec it gives my O/S a false reading and says its 65% charged, ima buy a new one and see if this is the case.... I really hope this works and thanks for your help!

[HOW TO] Startup/Charge HD2 with dead battery

how to fix a dead battery:
this fix is for when you can get into MagLDR but not into Android or WP7
1. startup phone
2. connect your phone to a charger
3. go to MagLDR Mass Storage mode and leave your phone in it for about 5 - 10 minutes, then start an OS and charge it like you normally would.
this fix is for when your battery is completely dead (direct shutdown after 1st splash screen or not even starting up at all) (will work on any phone)
(DANGEROUS!! watch out and DO NOT touch the cables when they are connected to electricity)
It is highly reccomended to use an external battery charger (like this one)
http://www.ebay.com/itm/Battery-AC-...114546?pt=PDA_Accessories&hash=item3f06ce2bb2
See the attachment. (paint FTW)
1. get an old usb cable
2. cut it open, and take the wires out it
3. seperate the red and black wire from the rest
4. take your battery out of your phone
5. put the usb cable in a usb charger
5. hold the red wire against the (+) and the black wire against the (-)
6. plug the charger into the outlet
7. keep holding it for 5-10 minutes
8. TAKE THE CHARGER OUT OF THE OUTLET
9. put everything back together and startup/charge your phone like you normally would
I did the above fix 2 times and it works perfectly but it is not recommended

an even simpler fix is to just plug the thing in and let it charge. If the battery is completely dead it will take abot 15 mins for it to get a charge sufficient enough to turn the phone on. I have run my phone completely down to where it just turns off and all I do is plug it in.....

When using magldr the phone will not charge when it is of. You just were lucky that there was enough battery left to boot it up far enough to charge again after it was turned of some time.
Sent from my HD2

[Question] - If the phone is in MAGLDR Menu and Usb is connected to the power?

Shouldn't the orange light be on?
Also if the phone is off shouldn't the orange light be also on?
(with the power charge usb on)

When in MAGLDR you will NOT see the power led.
If you let your phone totally die and can't start it boot to MADLDR and let it sit for 10-15 minutes to charge first.
Couldn't tell you about the last question. If USB is plugged in on my HD2 the phone will not power off, only reboot.

I will try to answer your last question with my HD2 running XBmod. When the phone is off and I connect it to charger, it will turn on at once, and then charge. It's not likely that with magldr you can charge the phone while it's off.
Somebody says in another thread which I cannot remember, that magldr does not allow turn-off-charging. Please correct me if I mess something here.

Hello,
Well it seems that my phone USB port is a bit loose or something like that..
Since the cable only charges it in a certain position.
Also I used a usb cable from a an LG phone and it's not good at all...
Didn't charge the battery, and yes the light of charge is on...
Like in the car when I plug it, the charging is almost nothing...
This also happens with usb charge on the pc...
But this is what I notice...
I'm not using the usb cable from htc.

The USB cable can be important regarding to charge. I have a Nokia Micro USB cable and another one just standard and nameless, maybe from BlackBerry og Samsung.
The nokia one with my HTC charger giver only around 50 mah when charging, observed by using HTC Battery Tool. It takes a whole night to charge battery full, and some times even still not full when I get up on the morning. And if I use the phone while charging, Battery Tool even shows that my phone is consuming battery.
The nameless one charge my phone with 500-800 mah and it takes exactly 2 hours to charge a battery from 30% remaining power to full. So I never use the Nokia one to charge my phone.

Need to install that Battery tool!

I had a similar issue, I cant be bothered pulling the cable apart but I suspect that a generic 2 wire usb "charging" cable wont cut the mustard, it possibly needs to be a 4 wire connection, all be it it only needs two of them to charge
as for your other questions, its all to do with MAGLDR
if the phone is OFF and you plug it in it "should" charge yes, but it wont if you have MAGLDR installed
If the phone is in MAGLDR or the bootloader for that matter, it will charge, all be it the light wont come on.
what isn't clear is if in bootloader or MAGLDR the device is capable of autocut off, ie, turning the charge to trickle charge once full, so my advice is that when charging in bootloader or magldr, only do it for 20 min or so then boot to your OS and continue the charge from there.

Well I now have adocking station to recharge the battery, got also a new battery...
The battery recharging is solved...
But the usb on my phone is ****ed up... since I need to "bend" the phone a bit for the light to turn on, but it only charges at Battery Current 250 - 300....
Ah well it's not a perfect world...
It sucks a bit that WP7 consumes the battery so fast...

Just don't bend it anymore or the USB will fall off the board. Data connection may become impossible to repair depending on the damage. And you will have yourself a permanent windows phone.
