This morning my HD2(7) was totaly empty. The power button did not do anything and the phone won't start up. When I hooked it up to the charger, the red led did not come up and the phone was not charged at all.
I tried to do a soft reset, but nothing happend. Some posts on this forum suggested a hard reset, but I did not want to loose all content on my phone.
It seems that the real solution is very simple. Just connect the phone to a charger, remove the battery completly and then place the battery back in the phone. The HTC will now start up and begin to charge.
So, just a waring, do not hard reset when you phone stops charging...

Funnily enough I put my phone on charge last night, forgetting that I'd also switched it off... Came to it this morning and remembered about the charging issue when switched off. Tried to switch the phone on and nothing... So I went to change the battery with the wife's HD2, but managed to mix up the batteries and found that my phone would switch on afterall and it was also fully charged. The wife had her's on charge overnight as well, so both batteries were showing as being full...
Charging issue has been fix up in the MAGLDR 1.13 version

There is no doubt that this is sensible advice, but there may be an overlap with another issue here.
I have noticed - and it could just be specific to my phone - that if the phone gets to the point where it shuts itself down to conserve power, it will often not restart from the power on button and only pulling the battery will wake it up. This seems to be a 'feature' of WP7 on HD2.
Interestingly, on several occasions where the battery has been fully charged (and still plugged in) the phone will not start from power on if I do a shut down - I tried it less than an hour ago after making a couple registry tweaks and only pulling the battery would persuade a fully charged phone to restart. It would be interesting to know if others are finding the same.
Where the battery is seriously discharged, it can take several cycles of pull battery - boot phone - phone decides it has insufficient battery and shuts down - pull battery - boot phone...before WP7 decides it has had enough juice trickled back into it to be able to charge - sounds crazy, but there you go.
MAGLDR v1.12 doesn't support charging, which doesn't help. I'm going to try v1.13 to see if agarp is correct - here's hoping.
Update: I don't think MAGLDR113 supports charging directly but I believe it has something built in to prevent a plugged in phone running down the battery. Not sure about exactly what, but it suggests something about booting the phone if plugged in and battery is at critical levels.

Does anyone know if the Wizard is capable of charging its battery in a completely powered down state?
The battery on my Wizard (G4 Qtek 9100) was low today, but I just ignored it, the battery ended up running down completely to the point that the phone powered off, and would not turn back on when I tried to repower it. I connected the charger and left it sit for about half an hour, the charging light did not light, but I left it to charge. After the half hour I figured it should have gained enough charge to power on, so I tried and no luck. Luckily I have a charged spare battery, so I left the dead battery in the phone and wedged thin wires in between the dead battery contacts, and the phone's spring loaded contacts. I connected the + of the dead battery to the + of the spare, and the - of the dead to the - of the spare. Now both batteries are connected to the phone in parallel. This allowed me to power the phone up and boot it all the way up, where the charging indicator LED lit. I disconnected the spare battery, so that the dead battery can charge on its own. Sofar it looks like it is taking the charge.
I'm wondering if some of the people that have "bricked" phones might have run into the same problem that I have. If you have a "bricked" phone, try using another battery that you know has a charge.
go in registry with totalcommander or something similar to this key:
HKLM\Drivers\BuiltIn\usbfndrv
and change : EnableUsbCharging to '1'
press reset after u done this.
i had this several times with death battery and wouldnt charge on usb on the
computer but it did with the original charger.
Thanks, i'll give that a try. Just curious, do you know anything about how that works? I'm wondering how a registry key can controll a piece of hardware that has been completely powered down, and that windows mobile hasn't yet booted on.
Hey guys.
I'm experiencing some problems with my Touch HD. When I get it to start I'm really happy with it and every program runs as it should.
My problem is the battery or something like that. I can have the battery power at 70% one second and the next the phone is telling me to either charge the battery or the device will shut down. I try to start it again but at the start screen it says Battery level to low, your device will shut down.
When I try to charge it the LED under the power button will show a solid amber light, telling me that it's charging, for about 7-9 seconds and after that it will either start flashing between amber and green light or just turn off.
I've tried having it like that over night and try to start the phone in the morning and the same message appear on screen, "Warning! Battery level to low! Your device will shut down!"
Read in some other post about someone who had a similar problem, but not quite the same, and that was resolved by removing the battery, plug in the USB cable for a few seconds, disconnect everything and then put the battery back in and start the phone. This works for me about 30% of the time. When it works the battery shows about 60-80% power.
I've tried a hard reset and I've tried to contact HTC without any success. Any suggestions from you guys, you seem to know almost everything there is to know about these phones.
Thanks.

Have you tried keeping the battery out for a day?
When I got my phone, the first 7 charges I turned the phone off and charged it all the the way up (to get the calibration accurate). Now the battery life is excellent, I can use it for couple of days without charging.
You should try returning the phone, seems it is fine software wise. Can you use the phone with the charger in? If yes, then there is probably something wrong with the battery or the hardware that is interacting with the charging.
I've tried keeping the battery out for about 24 hours but it didn't help. I can't start the phone when I have it plugged to the charger. I'm going to return it today and see if they can just exchange the phone in store or if they need to ship it somewhere to be repaired
Thanks anyway.
Sounds like a defective battery to me...
That's a good idea, better to get a new one.

switch off wifi, install Advanced Config, select all power management enabled
and try again. i also had the situation that my hd took 1550 mA. so the battery was sucked empty within several hours. now everything runs perfect...
Have exactly the same problem
I have exactly the same problem. One moment the phone works and charges fine and the next it shows irratic battery levels and eventually needs to be shut down. Following the shutdown you get the 'Battery level too low' message on startup, right after the Smart Mobility screen. In my case I think the problem mostly started when the phone was either just connected to a PC using the sync cable or when trying to top-up the charge using the wall charger. I also noticed that when the problem appears the plug symbol would appear (indicating it is charging) or sometimes not and then when checking the battery level, the indicators would actually go down sometimes losing 2 or 3 at a time until there is only 1 left and the phone says it needs to shut down. Pluging in the wall charger does not help as the LED indicating the phone is charging only stays on for a few seconds.
Now, I had many trials with removing battery, sim card, memory card or any of those in combination and sometimes these seem to work, but I think the key is the temperature of the phone. Every time I went to the car to drive home, where it was cold, the phone would start charging again, when just before that it would not react to anything all the time I was in the warm office.
I have now contacted HTC and am sending it to their repair centre tomorrow. Hopefully this is recognised as a fault and I will get a replacement. BTW, they arranged for a free courier pickup. Not bad, but the key for me is that the phone is being replaced as I really like the phone.
Update: Got a replacement after 1 week
Got my replacement phone today and hope that this time I have no further problems. I also had to return my previous one with a screen problem (see my post here http://forum.xda-developers.com/showthread.php?t=439410&page=2).
Everything went quite smootly and I liked the offer of a free of charge UPS pickup, so the only complaint I really have is that HTC send me a new phone but no replacement screen protector. Just the original screen sticker (the one with some writing on it) had been stuck on. It was in a bit of state like it had been taken off and put back on several times. I just called them to send me a replacement screen protector, but I don't hold my breath to get one. Probably end up buying it from the website.
Has anyone ever had an issue where by their battery life is at say 59% and when i plug it in to charge rather than the blue charging icon appearing it just showing the battery being 100% and the LED doing successive double flashing as opposed to a static LED like i should be if it was charging?
I've not installed anything, flashed a new rom etc, was fine yesterday.
All i did was have a little play with CHTEditor.
somethings not right, it must be something to do with me messing about with CHTEditor
out of the blue my lock screen had gone, and it says i have a voice mail waiting when i dont. haha
Hard reset i think
update...
hard reset not worked...uhoh
Same problem here
I was in a phone call an al of a sudden everything just went black and rebooted. Turns out the phone stopped charging and flasing green and red. Battery ran out of power and the phone shut down. After the reboot the phone charged normally again
Another situation:
Phone started acting up again and endend in a reboot. Battery was empty and i made a phone call on the charger. during the phonecall the same problem happend again, but the battery was at 9%. I intended to unplug the charger and plug it back in, but after the unplug the battery jumped to 0% and shut down.
So, i think the battery is acting up. Having to charge the thing every damn day is finally taking it's toll.

yep, using the original battery, it seems to be ok now, charging as it should.
ahh well. cheers for the reply
one last this, how the hell to i get the lock screen back, i think im being dim.
edit
sorted
I have a program BsB Tweaks that has a setting for the lockscreen. Try that.
My phone is also charging fine when turned off, also it functions fine at the moment. i think it has something to do with overloading the device when the battery is low. Based on that its not possible to turn on any phone when the battery is in attached but the power is, i think everything is drained from the battery while charging it and that when overloading the battery just doesn't pull it anymore.
i don't have a alternative battery, mine is original.
What are the symtoms when the battery is at the end of it's life? does it do this, or is it supposed to give a warning or something?
edit: i am unable to find a manual page describing the different modes the LED could be blinking. I'm curious what is says about the red and green blinking mode. Does such a page exist?
ok here is the problem.
4 nights ago i forgot to plug in my hd2 while android was running and the battery died.
the next morning i went to turn it on and the screen no longer turns on but the phone does boot. the battery doesnt charge, status light doesnt either, end key doesnt work, when i answer calls no noise can be heard or made.
any hope?
Im guessing you cant run bootloader?
Maybe this is a warrenty jobby
If you know someone with another HD2, Try swapping the battery.

Hi Chris,
Please eleborate/clarify your OP, because I don't think anyone gets this... At least i don't! You say the screen doesn't turn on but the phone boots?! How do you figure that? Your device is actually on because you can receive/answer calls!?! :S
Sounds like your device has just BSOD (Black Screen of Death) which is discussed quite a lot here. Just press reset button or pull the battery (please tell me you have tried that before...).
If your device IS NOT powered on, please try this:
Does the device vibrate shortly when pressing the End-button? If so you should leave it connected to the charger for longer. If battery has drained too much it takes a while for the device to allow it to power itself up (prevention of overdrainage, which Lithium-batteries don't like very much).
Do you charge through USB, or with the supplied charger? I've had this before trying to charge it with a (different brand) microUSB charger. Turned out most chargers only give out 500mAh, whilst my normal charger (and car-charger) give out 1000mAh i believe. That might help.
You can order a cheap replacement battery from China (i got mine with dockingstation), which is already charged about 60% (for storage purposes).
BTW if your problem is fixed, please add the prefix [FIXED] or [SOLVED] to your topics title.

i have restarted many times.
i use the wall charger.
but why would the phone boot but not turn on the screen or have the mic work?
remove your sd card and the battery. you may have to hit the rest button on the back after you plug the battery back in as well, but as long as you have the sd card out it should come back on. try plugging the phone into a charger and then remove the battery as well sometimes it'll wake it up so to speak. it's just a matter of playing with it. mine did the exact same thing and i freaked out for a little bit.
now if after all this it doesn't work and you've played with it for a while then yeah, best of luck to you =\. but whatever you do in playing with the battery and the charger, keep the sd card out until you can boot into winmo.
EDIT: never mind, i thought the phone wasn't booting. i misunderstood, but i went back and reread the original post. try reflashing your rom if you're in winmo and experiencing those issues. or take the sd card out and reboot.
i would suggest making an backup, as your phone turns on you should be able to estaplish a remote-connection with some (3rd-party-)software and do a hardreset.
if this wont work i would recommend setting it back to factory default (revert hspl if you have one and install stock rom) and send it in for warranty.
seems to be some major problem...
All this steps should be possible without screen turning on (working touchscreen may be needed for backup, but flashing doent need screen input)
if drive-mode is default for your usb connection and holding you from flashing you can do a hardreset and afterwards active sync will be default again and you can establish an active sync connection and flash
check if any of the pins that contact the battery are bended or broken, try to avoid removing the battery when you have to reset your hd2 because the pins are fragile
similar thing happened to me just last night!
I tried the jmz dual boot last night and I was nearly out of battery. I didnt look at any instructions I just installed it and restarted the phone to check out the new toy. it finally got done loading I chose android right away and I was walking towards the bedroom. when I went to see if android had fully booted and plug in the phone I had nothing! It was off. I decided that the battery must have died so I tried to turn it on and all that happened was the tmobile flash screen came up for a second and then it went right off, I got so desperate that I was going to do a hard reset but that wouldnt even work! the boot loader screen would just shut right off. I was suggested to try another battery we had at the house and bang it fired right up I took a wiff of my other battery and I dont know what happened but I think I let the magic smoke out cuz it is fried!

hello friend...i have a problem similar to this. basically when my phone is in android which i use alot if it dies in android, when i reboot it it will turn on for about a second to see my splash screen then turn itself off (the battery is obviously flat). so i plug my charger in and it stays on now but doesnt indicate charging....i boot it into windows mobile and the batt just stays at 0% but its still working. however once i unplug it it will die.....its like the battery is not in the phone. luckily i have two batteries and a dock which charges batteries, so i replaced the battery and everything works fine. once the battery that died in android was fully charged i tried it again and it was fine.................im guesing the moral to this story is dont let your phone die in android mode
I do notice my HD2 runs hotter while in android than while it runs in Windows.
I am not sure if that's an issue to this, which is why I never mentioned about it being hotter. Although my HD2 is noticeable hotter, it never gets to a point that I think I should unplug the USB due to overheating concern...
Just a few inputs from passed experience
I use TMOUS Stock 2.13.531.1 WWE ROM
2.12.50.2_2 radio (not stock)
k going to tmobile today to see if they have any extra batteries i can try.
then ill update
i went to tmobile. and while i was there i noticed the screen was turning on but very dim without backlight (barely noticable). but the rep helping me did not notice and i let it stay that way because tmobile is sending me a new refurbished phone as long as i send the old one (and the rep was totally cool he uses xda also and said they wont check my software and if they do they wont ask for the phone back). he also let me get insurance in case this happens again, instead i will just say its lost. so i basically killed 2 birds with one stone
Have a TMOUS purchased in May. Latest stock rom/radio. When the battery is super low it goes through the process of shutting down - but when I plug it into the charger the phone will boot instead of staying shut down and charge. Will attempt to boot then go into Sense then shut down again and do the same process all over again. The only way to stop it is to quickly power down and it will stay down and charge. In any of the situations the phone appears to be charging.
Is this a problem with the ROM/Hardware or is something going on with the battery? Have an 8GB SD card with Android (no boot loader) and thats pretty much it.
Any advice would be appreciated.
I doubt that your battery is gone bad, but there are chances, try to condition your battery
Its just a little strange that the when the supposedly dead phone is plugged into a charger it boots up without pressing the power button. Don't think thats normal. Also when plugged into a charger when the battery is "dead" or near dead it should boot up and charge. This one doesn't - it boots - shows an LED charge light and then powers down and reboots. For some reason the battery with such a low charge can't power the phone and charge at the same time.
Will attempt to do a hard reset - maybe HD2 Tweak or something else did something to the registry and try it again. Since its under warranty will request another battery and take it from there. Don't think anything is wrong with the phone's hardware because it functions flawlessly.

If the battery drains and shuts off because it's out of juice, it WILL turn back on as soon as you plug it in, but it shouldn't keep rebooting after that...
Also if it's just shutting down on you in Android without warning when it's low, you need to condition your battery in Android so that it has the correct batterystats info.
No something is wrong. Ran it out of juice in WM this afternoon. Got the error message let it go. Went down and shut off. Plugged it into a car charger USB/cig adapter. Powered up go to tmobile screen/radio code then animation - rebooted did the same thing without touching it a few times then shut off - light led for charging did not appear.
Pulled battery - when charger disconnected - plugged charger - red light no reboot. Tried it again - same results with a hitch - it froze when it was charging - accessed internet explorer then it did a hard freeze - had to press reset button.
Don't know whats going on at this point - it shouldn't have done the freeze. So I'm going to experiement - pull the SD card (has Android on it) and try it again without the card. Try another card, try another charger and see - if I get the same results its either the phone or battery. When I have a charge greater than 5% there are never any problems. Only when battery level 0-1%.

Your battery pins aren't bent are they? (The little guys on the phone side that smash down when you insert the battery)
No, they are fine. I did call T-Mobile this afternoon and spoke to a level 2 tech - they think the battery is bad. Under warranty and have to call HTC tomorrow morning.
The phone does charge and does get to 100%. Drain in Windows seems fine and uniform but it does drop quickly once I get to about 20%.
Because of the reboot issue I think one of the cells is bad. Doesn't seem to want to trickle charge when the battery is that low. Tries to reboot - but can't get enough juice to sustain itself. Should just bypass through the battery as its charging. Either its the battery or somehow the charging circuitry is bad - who knows - with a new battery if it still does it then is the phone's hardware.
Will stop using Android for a while until this gets worked out - although I prefer the browser over WM 6.5.

Def sounds like a battery issue then, if the pins aren't bent because that is the biggest symptom of bent pins.
