[Q] After several cycles on WP7 HD2 won't charge - HD2 Windows Phone 7 Q&A, Help & Troubleshooting an

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.

Experia: Battery status doesn´t update when inserting fully charged battery

Hi everybody,
I almost always managed to find answers on xda-developers to problems or wishes I had when tinkering with my phone.
Unfortunately, I haven't been able to find a solution for this one and hence my first post:
I always keep a fully charged spare battery with me just in case I run out of juice and I can't recharge.
However, when I exchange the run down battery by the full one, my battery status doesn't change and the phone switches off after a short while.
So far the only thing that works is briefly plugging in the phone with the replaced battery in it which will update battery status to 100% charge.
Obviously, this defeats the purpose of carrying a spare one around.
Is there a way I can force winmo to reset the battery status or another way to resolve it?
I don't mind if I have to rummage around in the registry if necessary.
Thanks in advance.

tat is the case with some batteries.. i have 3 batteries and only 1 that is acting that way.. all u need to do is carry a usb plug.. just plug it in when u are at work or anytin just for 30secs it will update to its full status.. or u can buy another battery so u get at least 2 battery that works..
Thanks Cutefox,
That sounds like a simple but effective solution.
I will try it next time I replace my battery.
the weird thing is that it does it with Ericsson's original battery.
Nevertheless, I may not always have such a plug on me.
There must be a trigger though when the USB plug is inserted.
If we know how WinMo recognises a USB plug has been inserted (maybe a switch in the registry), we can fool it into thinking it was inserted, and I wouldn't have to carry a plug around.
Any other suggestions?

nah.. its not about the plug.. its more of the voltage.. there is a trigger sumwer in the battery that switches on when you charged full. the thing is if you use a non-official charger like battery clip charger which im using, it is not as smart as the official SE charger/usb plug.. i think its due to the battery being charge outside of the phone too.. in the beginning it was always doing it so i thought my battery is faulty.. but after awhile, even charging it through the battery clip charger i sometimes come up with full battery.. so i got no idea why this happen.. another thing that could help is once u boot the phone up and it says its empty battery/low battery, do a software softreset.. that sometimes trigger the switch and turn on the true battery power for me.. only on stubborn times that i need to use the usb plug.
Thanks Cutefox.
I understand that in this case WinMo can't change the battery status without at least a minor external charge.
Let me ask you this. What eventually switches off the phone?
Is it the battery's power management chip that cuts further power to the phone, or does WinMo cut the power when the battery status reports 0% remaining charge.
In the letter case I could write a script telling WinMo to ignore the power warning for a predefined time, which should allow me to reach a power outlet.
i never tried tat b4.. but usually if its 0%.. there are times when i used xperia for extensively heavy usage and it suddenly shuts off on me while battery is still abt 20%.. i cant remember if its this battery as well.. since i always bring more than 2 battery it does not really bothers me as i got another battery to sustain.. but from what i recalled is not the windows mob status report warning that shuts it off.. more of the battery power itself..
Thanks Cutefox,
I guess I'll have to get one of those penlite powered emergency chargers to kickstart my battery for now.
In the mean time I'll continue looking for alternative solutions and report them here if I find them.
Does anybody else have ideas?
excuse my curiousity, but how the hell do you guys get the phone to stay on while you swap the battery? As soon as I take my battery out, even if the phone is in standby, it loses all power and cold boots upon putting it back in and powering on...just wondering as it sounds like a more viable option now to carry a spare batt!

of course you power the phone down in the first place before you swap it. you cannot swap it while its on. well u can and it will turn off but that is pure stuffing up the phone. never do it to any fone as per advised by a sony ericsson repair guy as it stuffed some of the IC chip inside. always power down before changing battery likewise any other electronic device..

Just keep it plugged in for 1-2 hours and then try booting in to try color screen bootloader and go from there.....
If you have MAGLDR installed then you can not charge the battery when the phone is off.
You should try to charge the battery using an external charger.
Edit: If you have a friend with HD2 and windows Mobile 6.5 then you could use the phone to charge you battery.
Wrong, you can charge it while it's off.

really? are you sure? because there are a lot of references to the magldr bug that wont allow charging (or even powering on without pulling the battery) if you try to charge with the phone turned off.

Wrong x2.
1. No one is fighting.
2. With new magldr, phone turns itself on when plugged in. Charging when off is not possible. The battery requires management which is only implemented in software. It may hold a small charge if you have magldr installed, but it won't charge fully, or properly. Also, it's not likely he's got the new magldr if he's returning back to windows.
Lastly, for the OP, what method did you use to return to winmo? And which winmo rom did you use?

Read? Phone turns itself on if you connect a charger. Phone has NEVER charged while off with nand. This way at least you don't have to pull the battery to turn the phone on.

Just in case: If you on same situation that described on first post try this:
Q: If you completely run down the battery, would you be able to charge it with the phone again?
A: If your battery is dead, press and hold Vol Down and plug in USB cable / charger at same time. Phone will boot into bootloader and charge there just fine. Leave for 20 mins, pull battery, reboot and charge normally. If phone has just run down, plugging in the charger will usually turn it on.

Actually i was on same situation and this helped on first try.
check the connection between battery and phone , the metal things i mean.
Perhaps, it is off the subject, but...
Poster #1: why do you want to get rid of this beautiful phone?
Just curious...
ok i bought another phone and i took out the charged battery from it and put it in the bricked HTC and it does nothing. now i know it was almost reverted back and i think the battery ran down but Iam not completely sure but maybe it could have been in the reverting software i used and maybe it just like lock up or something cause at that point you couldnt see the battery indicator. now i guess ill just have to sell on ebay for parts but it would be cool to try and un-brick it or try and figure it out.

[Q] HD2 won't turn on/charge

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

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.

Tutorial how to recharge phone when battery is drained!

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.

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

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

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!

[Q] Cant boot. Battery wont charge?

hey guys.
charged battery at night used it at work all day came home around 10 and battery was on 1%..went upstairs to charge but phone but was dead. when plugged into wall phone boots for 2 sec then turns off and boots again for 2sec....constantly looping like this? im pretty sure i just need enough charge so that i can boot into android and ill be sweet. but doesn't even get half way there!?
need help. cant charge.
im leaving the battery out for the night and im gonna try again tomorrow but any suggestions would be great!
thanks
Not sure but you can try this: hold down power button till mgldr menu comes. Stay in mgldr menu for some time and get some charge,then reboot.

Phone will not charge on magldr screen. Android needs to be booted to charge.
Get old USB cable, mini or micro, cut end off, bare red and black, take battery, connect red to + and black to - ,plug into wall charger and hold wires on battery for a minute or so, reinsert battery, should be charged enough to get far enough into booting to start charging.
First.. i had the same problem.
it have to charge while off.
before you cut off things, check the batterypins. one of them was broken on my HD2 (i saw one of them below my battery).
if so, try to hold that broken pin back while insert the battery and try again.
you could also buy a dockingstation (something like that: http://www.amazon.com/Fosmon®-Premi...P2YS/ref=sr_1_4?ie=UTF8&qid=1313518480&sr=8-4) to charge batterys.
I had the same problem once, I`m not 100% sure how i solved it but I think that I pluged it in that it started booting and removed then the battery. I think it doesnt start automatically if you reinsert the battery then... but I´m not sure about it...

thats correct, but relies on the bootloader being able to charge when off, so this method of fixing the discharged battery problem only works with winmo or cLK
Your right i had that Problem in the time i was running it with winmob andere haret

Charge while in bootloader or hard reset screen, it should charge from there.
However, the charging process using the aforementioned methods is kind of slow.
hey guys. thanks for your responses. i have left it overnight and it doesnt get to the 1234 bit. i have 3-4 cords so i cut one up however it has blue, red, white and green cords....whats positive and whats negative?
also my pins are fine.
this is killing me!
Thank you to samsamuel, i ended up cutting my old cable. connected the red cable to + and the white cable to - and left it for a hour. just booted my phone back up and got 1000 msgs and emails lol and im on 84% battery.
thanks again to everyone how posted!
much appreciated!
Good to hear,, for anyone else thinking of trying it, an hour is pushing it a bit, you are running the risk of damaging the battery since the charge control circuits aren't being used.
What Android build is this? I remember having a build once that required a special key combination to charge the phone up. I think it required you to hold the volume down and power while plugged in to the charger and it could charge from there. I don't remember exactly though.

Nothing to do with the build,,, if you have magldr installed the phone must be on and booted into android to charge.

EDIT: I realize now that it must have been something else, can't charge in HSPL or MAGLDR (duh). I have no recollection of what though (if anybody knows, let me know because it's driving me nuts now!)
OP, you do also realize that instead of cutting up wires you could get an external charger for your battery and just charge the battery alone, right? If you've wanted to buy one of those fancy desk docks you could get one that also charges a battery behind the phone
