Extended media battery won't charge - HD2 Windows Phone 7 Q&A, Help & Troubleshooting an

So I posted this issue on the boyppc wp7 rom thread but didn't get a reply at all.
Basically, after moving from Android to WP7 the extended media battery fails to charge. All I get is alternating green and amber lights when attempting to charge the battery.
I've tried the battery on another HD2 using android and it charges fine, tried it on a stock phone and it charges fine. It just doesn't seem to charge on any WP7 rom.
Has anyone else come across this problem? If so, do you have a solution (other than dual booting to android every time i want to charge my phone).
Cheers guys

The battery controller is a known issue with wp7 on the hd2, inshort, extended batteries will not work as expected, you will get batteries not working at all or they will only use the basic 1250mA
Remember we are lucky to even get to try this OS, but it will have bugs on our device

im having the same problem. i cant charge my battery and im looking for an external charger but no luck

If this helps...
I got an email from HTC accessories, if it helps here it is
"I have just been informed by our technique department that you need to update the firmwear for the battery for it to charge and work. You require wrom reversion 1.72.841.0 or later."

you just emailed HTC to ask them for help on an extended battery for the HD2 running Wp7?
and they told you to update the "firmware" to 1.72
i think there has been some confusion, the battery controller on the HD2 is different than the device this ROM was pulled from, our battery doesnt know what its doing because the drivers dont match the controller.

Run Android from the sd and charge that way, or I've read if you load MAGLDR, put the phone in usb storage, and leave say overnight, the phone will pick up the charge, not tried and tested myself but the android from sd in MAGLDR will definitely work. Pain in the ass I know having to change os but a half decent workaround until something else comes along.

magldr works, you dont need it to be in USB mode, and dont leave it over night, do it for no more than 30 min, that will give you enough to get back in to the OS, its unclear if the battery controller cuts of the charge, doing it for a long period of time "may" create some issues, like a dud battery, phone or a nice wee fire

Haha! Yeah mate, I can imagine a little fire by my bedside keeping me warm at night. It's pretty cold here but I'd rather use a blanket
Thanks for the help guys, I've managed to grab an HD2 with a broken screen to use as a charger. It's got the stock ROM on it so it should charge just fine.

Dead HD2 - Can't power/boot up

Update at post #26 (handset returned from HTC alive and well)
Urgent help required please guys - help me rescue my very poorly HD2!
Phone is completely dead at the moment. Battery is completely dead and attempts to charge it are not working - however I'm sure it's not the battery that's the problem!
I've been flashing different radio roms this last couple of days going from 2.08.50.05 to .08 and back yesterday to .05 because while on .08, the back of phone was getting really hot and the battery was draining very quicky. Late yesterday afternoon it discharged completely while I had it on-charge!
Since then it's remained dead! Initial attempts to re-charge saw the orange LED come on for a minute or two, at which time I tried a hard-reset but it froze at the point of making the selection to hard-reset after the brief bootloader screen. On one more occasion the LED came on for say 10 seconds before disappearing again and since then - nothing!
Taking the battery out for all of last night and at least 20 times today has made no difference. Trying to charge it via (original) charger and via usb cable has not worked. No LED, no charge (though interestingly it still gets warm at the back when on charge), can't boot, no response, nothing, nada.
Helpful guy in O2 shop spent 40 mins helping me out earlier today (he's a XDA forum user who flashes custom roms from here too on his HD2). He took his charged battery and put it in mine with pretty much same result! White HTC bootscreen came on for a few secs before dying again. Couldn't start/boot up my phone using his good battery, yet after putting my battery in his phone he was able to begin to charge it, proving I think that, it's not battery that's to blame for this, but an internal fault with the power-unit of the hardware, (and/or perhaps with the charging port).
I'm convinced that the power-unit is the major issue, and that as it seems to be over-heating quicky, then it shuts down immediately from doing anything. I could be wrong of course.
Sorry for the lengthy story guys, but now feeling really low that I can't seem to sort this. If I cant start it up or get to the bootloader screen then I'm not going to be able to flash a stock rom to get this problem fixed under warranty, so as you can see, I'm really frustrated!
Any help, advice, suggestions etc would be gratefully received and much appreciated too! Thanks in anticipation.
Edit: sorry should have said that I've extensively read these forums today and found many similar (but not exact same) threads/posts, hence the new thread.
hapened the same to me, radio 2.08.. to 2.05... white screen HTC freeze....not booting.
my solution was press the two sound boutons at same time, when the screen write HTC apears....them booting at radio specs...them press one more time de 2 sound boutons sf same time....
it solve for me the booting...is strange this issuie of downgrade the radio 2.08... to 2.05..
good luck.

Thanks pack21, but at the moment I can't get it to do anything at all - it won't start, it won't go into bootloader, and I can't charge it. I'd be happy to see anything on the screen at all right now! Thanks again.
since it cant boot why dont you take it back to HTC? They will first have to repair it since they dont know it has been flashed with an unofficial firmware....They might even give you a new device!

Yeah, that's what I'm going to have to do as a last resort, but my fear is that with their tech/tools, they'll figure a way to power it up or get it into bootloader and discover it has a custom rom, and return it to me unfixed. This is almost certainly a hardware fault, as I believe it has always been warmer (sometimes very hot) at the back than it should be, but trying to prove it would be difficult. It would be great if I did return it and they couldn't boot it, but I only want to return it this way as a last resort. Here's hoping someone out there might have another solution.
Can you power the phone up with the charger and usb lead plugged into it?
Have you tried booting wth the SD card out?
If you can at least boot it up then you could try MTTY to see if that helps.
Post your outcomes back up and lets see what else we can do to help.

Thanks for input WB - I note you've helped many others out on other threads with related problems.
Can't power up the phone by any method (AC charger or USB), and because it's got no power, I can't boot it at all. Tried it without SD card earlier, and it didn't make any difference. Even with someone else's battery in earlier, it wouldn't boot up or charge even, so I'm at a complete loss. Always thought I'd need to try MTTY sometime soon - just didn't know my device might die on me before then (and its only 5 weeks old). Any other thoughts?

Hmmm, tough one this.
I know that some of the newer roms are particular about which radio you have installed else you get a problem not dissimilar to yours, ie the device won't get past the boot screen. Yours being completely dead is a new one on me.
Do you remember what radio and what rom were on the device just before this happened?

Yeah, was on 2.08.50.05 until 2 days ago, flashed 2.08.50.08 to give it a try but noticed it was draining battery fast and getting v hot at the back, so reverted yesterday to .05 (but maybe too late, maybe damage was already done, because total discharge happened shortly after that yesterday).
Hey guys (WB and any others with any possible solutions), I need to hit the pillow (11.45 pm my time now and I need to be up 5.45 am), but please keep posting any ideas that you want that you might have, and I'll give them at go first thing at 5.46 am. Thanks very much in anticipation!
I think Kholk of the Eugenia project has done a lot of work with radio roms. PM him (nicely) and see if he can help.

Thanks for suggestion WB. I'll pm Kholk in a moment - whilst it could indeed be the radio rom that caused the overheating and/or discharge, it seems that whatever caused it was catastrophic because I still can't get any charge into it, and hence I can't boot it up!
I hope sincerely other HD2 owners do not suffer this same problem at any time - it's proving a nightmare to fix.
My advice to all would be ignore those who promote the idea of allowing your battery to fully discharge - especially if it follows an over-heating handset - you may never recover from it (like me at the moment)!
If anyone's got any other suggestions for getting my handset powered/booted up - I'd be delighted to hear them. Really don't want to return to HTC with a custom rom on it!
The Radio ROM contains software parts that are critical to your device (at least for HTC devices) as it contains the OEMSBL (the radio bootloader) that boots ... ALL!
So, if you flash a wrong Radio ROM (as for example flashing a Diamond radio on Leo, or every radio that is not compatible with Leo: remember that for Diamond/Blackstone/X1/Raphael the radios were compatible) you'll get a totally bricked and unrecoverable (if not using JTAG!) device.
BUT.
You've flashed a Radio ROM and your device booted successfully, so, no errors during the flash process.
Assured that this Radio ROM is compatible with every HTC HD2 (TMOUS and EU), this Radio can't have produced an hardware fault on your Leo: it's almost certain that it is a coincidence that your Leo died with this Radio!
Anyway:
1. Be sure that your battery contacts are sane: check that they coincides with battery contacts: if you swap fast a battery you can do a wrong gesture with your hands and fold youre device's battery contacts.
2. Check the battery LED near the speaker: does it power on? (orange/green)
If the battery contacts are sane and the battery LED doesn't power on, maybe your battery is fault OR it is really completely discharged: on my old NEC e606 if the battery was completely discharged (0A, 0V) I had to charge it "manually".
However, if these two steps aren't helping, try this:
1. Take an AC adapter of maximum 5 Volts, or an USB cable
2. Cut off the end of the AC adapter (or the other end of an USB cable) and connect positive on battery positive and negative(GND) on battery negative.
3. Make sure that the cables are correctly connected and that your power source (AC Adapter / USB Cable) is connected and/or powered on.
4. Mantain this position for 5 minutes: your battery will take some power (yes, it is a really raw charging process)
5. Don't wait more than 5 minutes: it is a raw charging process and it will never stop! (well, not never, but if you wait for too much time, you'll **** your battery!)
6. Battery slightly charged: disconnect it from your power source, take it into your HTC HD2 and connect its battery charger.
If it works, well, you're saved, but I think that there is a fault with your HD2 because for a complete discharge of your battery you have to wait for weeks....or months! Or even years!
If that doesn't work, try with another spare battery that is known to work.
If your HTC HD2 doesn't work even with another battery, RMA it, HTC won't see that you've flashed an HardSPL, a new Radio and a custom ROM because they'll simply replace your mainboard.
Let me know how it goes!
Hope that this helped.

Hey kholk, huge respect for taking the time to consider this serious problem of mine! Thank you for the different options - I'll work my way through them and see if any can bring my HD2 back to life.
I can confirm that I've successfully flashed roms and radios (via SD) and never had any problems, and I think you're right - it wasn't the switching between 2.08.50.05 to .08 and back to .05 - it was probably just a coincidence that the unit got seriously hot and discharged at the same time as I used .08 (hence the reason I had just re-flashed .05 when it happened).
Battery contacts are good - checked them carefully yesterday.
I'm convinced the battery is as dead/discharged as it could be; since yesterday morning I've not even had a glimpse of an orange LED when connected to AC or USB charger (though the unit continues to get warm at the back, but doesn't get hot any more). I'll try your ideas for getting some life into it, and I've got a replacement battery on order, but as I found out with a friend's spare battery, it still won't boot up or allow itself to be charged.
I think therefore that it will ultimately need to go back, but I'm grateful for your assurance that HTC are unlikely to know that I've got HSPL/Custom Rom and Radio on there! Many thanks again for now (its so re-assuring to know that if you come across occasional difficulties, there's some good guys on these forums who will try to help bail you out)!

That's 2 bad nights sleep now, as this happened day before yesterday . Thanks - fingers crossed eh, both for getting mine fixed, and for hoping this is not going to become a common problem for other HD2 owners!
Well, if the device won't power up even with a known good battery, then HTC isn't able to power it on magically. Your hardware got a fault and the only fix for this is replacing the faulty part.
And no, HTC won't desolder and resolder a chip on your mainboard: they'll replace it completely!
I'm sorry for your dead HTC HD2 and I know how you're feeling... I've experienced the same.

Thanks again kholk. Reading what you've written confirms for me that there's not likely to be an easy fix for this and so I should give up on that idea now and just get it returned sooner rather than later for a warranty repair. If anything develops from this I'll be sure to post an update for the benefit of anyone else who might experience the same difficulty. Much appreciated again for now!

I had very similar issue on my X1 when I left it plugged into my car by accident, it totally drained the battery and wouldn't do anything other than blip a red light.
I swapped to my spare battery and the phone booted once, said low battery (was fully charged the day before) then did the same red light.
After much fiddling, it turned out that I had to leave it on charge for around 12 hours for the battery to kick back into life and boot the phone. Then it took a further few hours to charge it again!
Older devices could only be chared with a HTC stock charger (when having a dead battery), cause they delivered a little more power then custom AC chargers (like the one for your BT headset).

Charging new battery with NAND

Hello guys,
I'm buying a new standard battery because my current one is going bad. Meanwhile, MAGLDR is known of not charging battery correctly while the phone is off. What should I do know since I heard that new battery must be charged first while the phone is off. Thanks.
The new battery will come with some charge in it. It will not be empty. Lithium batteries do not have 'memories', you do not need to give it a full charge to get the best performance out of it as you used to have to do in the old days. Google for Lithium battery information if you are unsure.
Don't worry about it
Insert the battery, boot into Android and charge it.
Afterthought...
If you are worried however. Just backup your build, flash Windows Mobile back on to the phone. Turn the phone off and charge it with the phone off. Then flash MAGLDR again and recover your backup build.
thanks man, I heard about that too but what makes me doubtful is if that's correct then why almost all phone manuals instruct us to charge the battery until full before turning phone on for the first time.

From personal experience I can say it's pointless to charge full while the phone is off.
All i do everytime is use the charge the battery came with untill the phone turns off by itself, then turn on and plug the charger for 16 hours.
If you do this - full cicle - several times in the begining, the battery is working perfectly.
This way the cells are loaded to the maximum in the begining and the battery is "conditioned"
the use of HD2 with Android is quite a different issue...
Dont know bout all builds(I have nexusHD2 1.9a) but I charged my battery after my phone went comatose-just connect the phone to power with battery and -then- turn it on.If that doesnt work you can always buy el cheapo charger from Ebay.
I bought new battery from ebay,which works great.10$(M | less)for battery+charger.
Cheers
damn, so many different thoughts about li-ion battery i don't know which is the best one.
anyone else? before i receive my new battery tomorrow

[Q] After several cycles on WP7 HD2 won't charge

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...
Sent from my HTC HD2 using XDA App
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.

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'.

If you could do some pics that would be great...I have two, "My computer's broken," calls to deal with today. Visuals might help some...it's appreciated.
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.

Bricked

Need some help hope i post this in the right place. i have gingerbread on my HTC HD2 and was converting back to windows to sell on ebay and i started it was almost done when i relised before i started i forgot to charge the battery and it ran out before it was done know the phone what turn on at all. i plug it in the wall charger nothing, plug it into the computer nothing tried everything nothing. do you think that the battery is that dead and it was in the proccess that the chargers dont work on it no more. would it work maybe if i had a charged battery to put in it. it mite come back on. any help would be great thanks.

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.
well i tried to charge for the last 2 hours nothing tried to remove battery nothing. Iam going to try and find a charged battery to see if the phone mite turn on or something. ill post later to let yall know what happen tho. thanks for the help.

Just give it a try man and see for yourself whether it charges or not....
what are you guys fighting about man, they just updated the magldr v1.3 and yeah we can now charge the phone while its 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?

Find a way to charge your battery and everything it's going to be just fine.Your phone it is going to work.
Changing the battery should work.
I'm new here so basically with new 1.13 or later phone can't be charging if it's not turned on?

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.
Its found on one NAND thread and goals goes to g.lewarne
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.

stuck in bootloop. cannot get past magdlr

I didnt charge my phone for awhile. I recently plugged it back in and now I cant get past magdlr. After the 12345 GOGOGO it restarts endlessly. I can enter the magdlr bootmenu but cannot enter AD recovery. I heard magdlr doesnt allow charging when android isn't booted which is absolutely retarded. I dont have access to another phone to charge the battery or an external charger. Id prefer not to cut off any of my usb cables either. Are there any other solutions?
Or is the battery dead? I check the pins and they all look alright.
You could try to switch to clk but you will have to do it quickly in order to have some battery left and it's risky since it could interrupt the flashing etc.
Or you wait some time and retry after some hours and plug it on when you try next time.

Hey mate, the best bet for you now is to flash a WM ROM. If you already have one in your PC, then you are in good shape to recover your HD2. If not, i suggest you download a suitable one(preferably stock) real quick.I hope your battery level is at least at 40%. Anyway, even if your battery is dead, all is not over. Just find someone with a HD2 or concoct some bull**** to tell your local smartphone repair dealer and get your batt charged. Dont worry,your HD2 will definitely breathe again and you can run Android in it again.All the best
Cheers

Not true. When put in charging the HD2 starts.
You need to go back to stock or install clk. The 50% battery is not a must when flashing. Clk will charge your phone when turned off. Magldr will not. You need to do something quickly to get your battery charged, then you can decide on a from or something else.

could be simply not enough charge to start booting, since there is a large current draw after magldr boots,,,id give the bare wire usb lead a try before reflashing, , if you have a spare usb cable you dont mind destroying. cut the end off, (any uab cable, deosnt have to be for this phone, standard, mini, micro, doesnt matter, ) bare teh red and black and hold red to + and black to - on teh battery for about a minute, , should have enough power to get into booting, and charging starts about halfway through booting.
(course, it might not be that problem, but if you have a spare cable it cant hurt to try)

true, and since you're so full of criticism, how come YOU dint hack a winmo device to load up a custom bootloader into the space where a splashscreen goes to allow all kinds of things to be done to the hd2 , ****ing retard. Hope its bricked.
First, install CLK or flash a WM ROM. Then you can do a full clean installation of Task 29 onwards, including reflashing Magldr. And son, you cannot expect all features to be integrated into Magldr. Most probably, a simple reflash of Magldr should solve your problem, but for now, get your batt charged.

your first part of your post is helpful mate...but lets not start a keyboard fight here...chill...
Or just go into the bootloader (tricolor) and stay there and charge the battery from there. no need to boot into Android
lol, and the years old argument 'does it charge when in bootloader?' resurfaces once more,,,

yes, it does
no, it doesn't, and so it goes on. Hehe.
(Not that I expect to convince you, of course, you've been around near on 3 yrs or so, so you've seen the numerous "yes it does no it doesn't mine does bet it doesn't your wrong no I'm not" threads about this, , but consider this,,, if it were really that simple, would we not have a deffinitive answer by now?

well, i guess you have to try it, then you will be convinced i wouldnt post it if i did not try that procedure before it takes a little longer to charge due to the display. its on during charge. I mean guy has nothing to lose, for me this works.
hehe, i DID try it, lots of people have, and the outcome? some say it does, some say it doesn't.
My own theory is that it does allow some residual charge to build up, by warming the battery if nothing else, making it seem that a flat battery is no longer flat, in the same way that leaving any almost-flat battery for a while,warming it in your hands and such, makes it work a little more, but from the test i ran (admittedly about two years ago), i started with 10% power and left it two hours, when i booted winmo it read 8%.
But as i said, i don't have any delusions that i will convince you (or anyone else, for that matter), its one of those questions that are best left to the individual to try it out.

hmm i know you are one of the guys, whose know what they talk about. It really seems, that for some it works and for some not.
Yesterday i tested it that way:
battery was at 63%, booted into bootloader, waited 45mins, unplugged the cable, and booted into android (cable still unplugged), battery at 74%.
A bit strange, if the heat would add 11% of charge to the battery. But hey, its HD2, never say never and everything is possible (well not really) D
i will test it once again now.. conditions: 75%, connected via usb to pc, not to the charger. I give it 2h. (poor display :/)
after 2 hours of charging in bootloader, my battery is 98% charged. I guess i am one of the lucky guys
@greg17477
With standard charger, works for me too. Maybe if you have an inappropriate charger and display drain all charging current did not work.
hmm interesting, if a water pipe hadn't just burst this morning (i'm on a break, covered in wet plaster and sawdust) id retest it myself, , perhaps i tried it in the pc or something.
I shall certainly start advising people to give it a go from here on out.
well i stand corrected. just shows how things you take for granted aren't always so.

respect, you have some balls
btw. as long as it doesnt hurt our hd2, people can try this method. nothing to lose there.
