After several cycles on WP7 the batt was fully drained and now it won't charge (charge LED goes on for few seconds and then goes off). It won't load either, just switches off on DFT screen. Batt is standard.
Guess it is critical not to allow batt to drain fully on WP7?
Is there any solution to this?
Thanks for any ideas.
Had a similar problem with Android...battery drained completely and wouldn't charge. I solved it by cutting the end off of a spare USB cable, removing the battery, and charging directly from the cable (red wire to positive/black to negative). After about twenty minutes I put the battery back in the phone and it booted Right up. Or, if you have more sense than me, you could just pick up an external battery charger...I'm just the hack apart a cable and do it caveman kinda Guy...

I can confirm a similar experience; I thought it was worth trying the fully-drain-then-fully-recharge regime suggested elsewhere on these forums as a means of extending battery life, which does struggle a bit on WP7.
The fully discharge bit was easy, but it is worth everyone bearing in mind that magldr - as advised, I believe - will not allow the phone to charge. As a result, I was getting into WP7 (just) only for it to almost immediately shut down. But it was at least doing a small amount of charging before it did.
After a sweaty fifteen minutes or so of restarts (I was having to take the battery out to force the restart as it wouldn't start on the power button), it decided it had enough charge to...well, charge and all was well.
My suggestion would be not to risk going beyond the critical warning WP7 gives, at least until magldr is able to offer charging.
Almost the same issue here, without having let the battery fully drained...
I can't charge my hd2 anymore.....if it's turned off.
But, it Can be charged if wp7 is running! I don't know why...
I had This issue when I received the phone. It took me a whole Day to charge the battery the first time : orange LED turning off after 10seconds (HD2 switched off or in wm6.5
Once the led is off, can't turn the phone on or charge it again until I remove and put the battery back.
It was in summer so I thought the phone was too hot, so I cooled the battery with a fan, replaced it, retryed... At least 10times, and it finally charged.
SO weird, I'll test This again with wp7, who knows?
I am wondering whether it is some kind of magldr bug?
I'll try the trick with the cable directly to the batt. It is not very practical though if you drain your batt, where there is no access to spare cabling.

This should be put into the sticky rollup thread for people who have let their batteries drain.
Why dont you do some pics bud and create a topic?
I am cutting the cable as I write. Will take some pics.
If your battery drains completely, just remove it, replace it back. Without starting the phone, connect it to your PC. start and enter the bootloader. You'll be then able to charge. I did it like that last week.

Running cable directly to the batt is confirmed to work. Just revived mine with this trick.

How do you enter the bootloader, if the phone is not responsive at all?

Less of a bug and more of an unwanted side-effect of having this excellent capability, I think. I seem to recall that the developers are aware and looking to see what can be done.

I guess it is possible to completely drain the battery, in which case this won't work. But if there is some power, removing the battery and replacing it should kick the phone into life for long enough to do this. This was going to be my first try if persistent rebooting hadn't eventually worked.
having this problem and definitely charging below the amount...
i cant fully charge the battery as well
Like I said, if connected, but not started, to your computer, you'll have enuff time to start it then and entering the bootloader, of course, you gotta be quick for this to work.
If it doesn't respond, don't laugh, confirmed to work, remove your battery like explained and put it for some mins in the fridge before replacing it (it's only chemistry playing here, somehow better than cutting a USB cable in 2).

"storing them in the freezer might be more practical. These kinds of batteries lose their charge after a few days when kept at room temperature. But they'll retain a 90% charge for months if you store them in the freezer. Just like alkaline batteries, you'll need to wait until they've warmed up before using them. However, this isn't a problem when you need new batteries for your digital camera or other electronic gadget. "
I suggest you to be more polite when answering and learn your lessons before posting!
I finally made a dual boot Android/WP7.
At first, Android said my battery was fully charged, just like WP7, which is totally impossible as I used MAGLDR to format the SD card (wp7 & android partitions) and that it took me almost 1hour, without any possible way to charge the battery while I'm in bootloader mode.
But when I turned the phone off, plugged into the wall.......TADAA It was finally charging, with phone turned off
So, it seems that dual boot may be a way to solve this issue

You're arguing against yourself here aren't you? Cold may be fine for storage but you need heat to coax a little more power out. You even say 'you need to wait until they've warmed up before using them'.

Wrong idea, sorry guys.
I thought that HD2 was charging since I installed WP7 and Android in Dual Boot. But it's a fake : if the phone is turned off, and that I plug it, the orange led turns on. But that's all, even if I unplug the phone, the led remains turned on !!
And now, Android as well as WP7 are telling me that the battery is fully charged but I'm sure it's not even 50% full.
hi guys i have htc hd2 w7 ,and im hang trouble with charging it..heres what happen..if my phone goes lowbat and charge it, it wont charge i have to take out the battery and put it back in so it will able to charge..please help..
thank you
Turning it on and off would probably help. Or try charging it when the phone is off.
the phone is all deway off. iu cant turn it on..you have to take the battery out..so i will able to turn it on

There are some very odd battery issues with this at the mo, in short, dont run your battery down flat.
Charge up your phone, install the HTC battery tool, run it and make sure its full,. ACR should read 1250ish, it might be a bit below that depending on age.
then use the Battery reg tweak to set windows to report the correct battery levels.
but you still may have issues charging, it may requirer you to restart and charge, and/or unplug and charge
Also dont reboot with your USB attached, it doesnt like that just now!
any solution for this yet??
thanks
My Phone won't turn on, even to load into magldr when charged. The phone sometimes vibrates when I plug it in, like it's trying to turn on, but doesn't have enough battery to load into magldr to charge...
The phone worked fine before (except semi-regular restarts, probably due to the memory card), so do you think the battery is the issue? If so should I just buy a new one and hope that it has enough charge to load magldr, then charge, or is there a way to charge the battery whilst it's not in the handset?
Cheers
Try making sure that the pins are both aligned to the battery.
thanks, you just saved me a tenner
can't believe i didn't think to check that...

No Problem
Incidently, i know you got it fixed which is great but for the record and anyone else searching for this.
If your battery is nackard and you cant get to WP7 and MAGLDR isnt able to load to start charging that way you can try to warm up the battery a bit, dont use a direct heat source, but just warm it slightly, dont over do it, or it might blow up, you'll help the chemical reactions inside which "might" be enough to get you in to magldr or even WP7 its self
anyhow, glad you fixed it!
If my battery dies completely, sometimes it wont turn back on and wont charge. But I found that if you pull the battery, plug the charger into the phone, and then put the battery back in while its plugged into the charger, it seems to fix the issue. It turns the device on and begins charging once again.

amazing advice! thanks given =D
So we all know the major problem with the WP7 roms.
You can not charge your phone when battery is completely drained!
Now here is the solotion. This requires no apps, no mods. Just your own handeling!
So what to do when battery depletes?
1. Plug your phone into a powersuply.
2. Turn on the phone and keep the power button and both volumes buttons pressed. (this is called a hard reset.)
How to hard reset HD2, view the first 17 seconds. Ignore the VolUp!.
3. You will receive an message saying:
''This operation will delete all your personal data, and reset all settings to manufacturer defailt. Press VolUp to restore manufacture default, or press other keys to cancel.''
Click to expand...
Click to collapse
4. Do not press anything. Let your phone be for a couple of minutes. I keep my phone laying for a minimum of 10 minutes.
You won't see the phone charging (no orange light in upper left corner)! Believe me it is!
5. After 10 minutes restart the phone. If ''press any other button to cancel'' does not work. Take out the battery, keep battery out for 5 seconds. Restart phone.
6. Phone will start. After windows phone loading screen you will see the phone is charging. If you kept it on power. If not, you didn't follow my instructions.
Tip: to avoid battery drainage!
When the phone is making the bleep noice warning for critical energy level, turn off the phone and keep it at a warm location. Ideal is to take out the battery and keep that to as warm as possible. Batterys barely drain when they are in warm enviorments.
I am not responsible to any damage done to the phone!
I done this multiple times, all times it worked fine for me!
If it helped, Thank me and leave a comment
when i'm on the road there is only one warm place i could think off, besides my armpits...
but your method works, have faced it once.
Thanks for the conformation.
To bad the HD2, is kinda big... doesnt sit that well.
magldr works as well
whats not clear is if the battery controler is in use with this method, so be warned, dont leave it too long, if you charge it for no more than an hour it will be ok
mains power adaptors usually give out 1Ah, take in to account that the screen is on full, this should give you around 700mA, more than enough to get in to windows to charge propperly
USB charge will be half that, most USB ports only give out 500mAh so an hour will give you approx 200mA again, thats enough to get you in to windows
Overcharging a battery can have some side effects, firstly is reversed polarity, meaning it wont take as much charge in the future, or it could heat up a lot, which isnt good for anything, the life of battery or the device its self.

That is true, but I recommend trying it for a minimum of 10 minutes keep it on charge. and as soon as windows pop on it recharges normally.
And didnt knew magldr did the job as well, the only problem is if you deplete it to badly it doesnt go past the HTC screen in the beginning.
all this is completely unnecessary.
easy fix solution:
1. Pull the battery out and USB cable out (if connected and charging)
2. Plug the USB into the phone and allow it to charge without a battery (it will not, duh!)
3. Put the battery in while the HD2's connected to the USB charging.
4. Observe that you can boot all the way back into WP7.
enjoy.

I did not know that.
Well thank you. Although I am not such a big fan of taking out the battery when its not needed. I mean the change is short circuits with the connecting points when taking out, when powered or putting in when powered it larger. Now I heared from a comment above that MAGLRD does the trick as well. Now that is far more easier then all the others given above, Yours and mine
good tutorial on this. I cant believe the battery wont charge when dead thought this was a faulty error of the phone.

theres 3 methods on here,
bootloader charge
magldr charge
remove battery charge
all three will benifit frm heating up the battery, do not cook it, or it may blow up
there is a 4th way but i dont recomend it unless nothing else works
take a usb cable mini or usb printer cable
cut off the end connector
strip back the wires and seperate them all, you want the red and black ones
make sure all the wires cant touch each other, cover the 2 unused wires with tape i
then connect the black wire to the (-) negative and the red wire to the (+) positive
tape them in place
the 3rd contact point on the battery isnt used in this method
finally connect the other end of the usb cable to the computer
dont leave it too long and when disconnecting remove the computer end first

It bypasses the system somewhat. Don't know what happens when battery is entirely drained, but it is worth a try.

If it does not help. You can buy a new battery.
Click Here. Its not that expensive, a official new battery from HTC is around 30$is around 20Euro's.

Thanks for this timely post Lemonspeakers. completely drained the battery listening to music on loudspeaker and didnt hear any warning. Couldn't hard reset then checked this thread.
On putting in the battery after charging the empty phone, the screen kept cycling between mgldr and HTC splashscreen so booted into sd android and the phone is fine.
I assume I didnt charge the empty phone for long enough (30 secs), I didnt warm the battery and I suppose I could have left it cycling until it charged up a bit more.
Thanks again

That might work.
Otherwise maybe a phone repair shop, there is equipment that can charge your battery outside an phone. An emergency charger its called if I am not mistaken.
you could inform there.
its showing symtoms of it bring bricked. cause it doesnt charge, it doesnt turn on without the battery, and yeah conclusion is that its dead!
Hi,
Since yesterday my phone (leo/hd2) died and when ever i tried to charge it it would go in to a boot loop then back to normal booting (as in wp7 bootscreen) but now a day later it won't even charge! I have checked the pins tried different cables and still nothing. Also there is a small red tab on the bottom of the battery near the connecter which used to be pink.
Maybe your battery is completely drained? If so, check here.
it won't even turn on so i can't perform this > does this mean it's dead?
have you tried a different battery because you have used a WP7 rom and when the battery drains out it can not be charged ( unless charged on another phone) so i recommend you using a different phone to charge your battery or get another battery into your phone
Thanks, i'll try that now. But does the red tab mean anything?
Hi,
I have this very often. Problem is that your battery is completely drained and the phone doesn't have enough power to start.
This is how I solve it:
start charging your phone
when it switches on, keep pressing the power on/off button
you'll arrive in the magldr boot screen.
just wait for about 5 to 10 minutes
start windows phone (it's possible you'll have to remove your battery and put it back in your phone).
Voila WP7 starts without any problem.
good luck!
try an external battery charger/universal battery charger. (i recommend keeping one handy whenever u r messing with wp7)

Piece of crap?
Whoa, cannot agree there...
If you carefully follow all the tutorials, hints and tips here at xda, HD2 runs fast and smooth with several OS´s of your choice.
However, there is still a possibility that your device is defective. Or the cable. Or whatever. But that doesn´t make HD2 a piece of crap in general.
Lol, its the charging port and a defective rom once i fix both i will have to go back to miui ;( Is there any rom which allows charging while the phones off.
Hi,
It's not the rom, it's magldr...
Koen
What do you mean? Do i need to downgrade? Can you charge while it's off?
if u have 1.13 and u can reach the magldr screen then plug it in,quickly switch it to usb masstorage mode. but dont keep it there for long as the screen will be awake all the time.
try keeping it that way for 15-20 mins,it shld give u enuf juice to boot it up

what he meant was that,its not the ROM's fault that u cant charge it while the phone's off,
you see,whenever u plug in a switched off phone,it quickly boots into the magldr mode,before booting ANY OS( or any version of any rom ),and thats y it wont charge while switched off(unless future magldr provides this function)....the only reason WinMo cld charge your phone while switched off is that it dint need MAGLDR before booting
try the usb mass storage method if possible,it works
hope i helped ya
dont forget to thank all the hardworking developers
I always have a problem with aftermarket chargers and charging through USB. It won't chargers in both scenarios....any body has an idea on that?
When my HD2 completely drains i just attach the (original) charger and it will start cycling boot...but eventually the battery will be charged.
