Problems charging battery

I think I may have a faulty battery (hoping it's not a problem with the phone itself). The battery seems to hold it's charge ok but when it has completely run out of charge or is close to running out, I have a lot of problems getting it to charge up.
If the phone is turned off, the orange light comes on but then goes off again after about 10 minutes and the battery still shows 0% when I turn the phone on to check progress. I have to remove the cable, then remove the battery for at least 5 mins, turn the phone on and while it is booting up, do a soft reset. I then insert the cable as the phone is booting up and after a while the orange light comes on and the phone starts to charge. It takes ages to charge and when it has got to about 20%, I then turn off the phone and it then charges the remaining % fairly quickly. It only gets to 99% though....
I am pretty sure (like 99.9%) that it is just the battery as my son has the same phone. We have swapped chargers - no difference. We then swapped batteries - my phone worked fine and his wouldn't charge! However, when I went in the Orange shop they were insistant that I had to send the phone back as well, which I really don't want to do as I haven't got a spare phone (even a brick).
Unfortunately, as I have just lost my job, I don't want to have to buy a new battery as they are about £25 but I guess I will have to.
What do people think - is it just a faulty battery? Has anyone else had this issue with their phone - i.e is it a known problem?? Hope someone can help...

I guess no-one bothers to answers questions from newbies then....

idd, i feel the same way..
but i think your battery is dead, don't have much experience about that subject but when you exchange the battery with someelse and then his phone acts weird to, look no further.

Let Andriod die now have a paper wheight

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

Sign of bad battery?

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.

X2 Charging problem

So the phone was really low, at 6% this morning. SO I put it on the wall charger. I saw the icon come up that it was charging and then put the phone down.
A while later I went back to the phone and saw that although the charger was plugged in to the wall and also plugged into the phone, it was NOT charging.
Using the phone I went to my contacts to check a phone number and then it turned off, due to no charge.
I plug it into the wall charger, the USB connected to the computer, as well as the car charger and here is what happens:
The top and bottom of the phone blink red for about 1-3 minutes.
Without pressing anything on the phone it automatically turns itself on, I see the Sony Ericsson boot screen, the Windows boot screen then my SPB Mobil Shell screen for about a second and then it turns off again showing and the blinking red light for about 1-3 minutes and then it starts the process all over again.
I think that a setting for Backlight/Power management was changed. As setting similar to "Only charge with usb", or "only charge when connected with ActiveSync" or somthing like that.
The problem is that I turned off the Active sync on the phone in order to conserve battery power so that I could look up the phone number from my contacts. And after I did that the phone shut off and I cannot change it, because it will not charge.
I do not have a different, charged, battery to try and do not think that I can find one easily.
Any suggestions?

Now when I see that the phone is re-booting(I see the SE logo), I use the stylus to to soft reset. It is obvious that there is some type of charge happening before it re-boots, , otherwise it would not re-boot. SO my theory is that by doing a soft rest between restarts, the battery will gain more of a charge each time. And possibly have enough of a charge so that I can go into my settings and see the backlight/ power settings have been changed.

So I took a battery from my old SE 902 phone and rigged it to work with my X2.
It booted up just fine. I was able to get into the menu for power settings. Nothig was changed however I did check the box "do not charge when connected to the computer" backed out of that screen and then went back into the screen and unchecked the box.
I powered down the phone and the screen went to the default charging battery meter.
I then put the proper battery in the phone and it was still blinking red. I saw it blink green for a few seconds, then I felt it vibrate, and then I saw the green battery meter. But after a few seconds it went back to blinking red and I could not see the battery meter again.
This seems to be happening intermittenly. As of right now there is a green blinking light and I see a dimmed battery meter.
Hopefully it will be fine, we shall see.

So it was charging for a while and now has stopped. I see the battery meeter, but there is no green bar moving up. and the light has stopped blinking.
I unplugged the usb and I still see the battery meter with no green bar moving. Installed the back cover and plugged the usb back in.
Now it is back to the red blinking again. . . ? ? ? ? ?

I think that it is a battery issue.
CAn anyone suggest why a battery would all of a sudden stop working?

Just ordered a new battery. $70.00!!! Ouch!!!
It does come with a battery charger for use with a Mini USB, but still, $70.00 is a lot of money!!
I will update with the results after i charge it up.

I got the new battery and put it into the charger. As I mentioned in an earlier post the new battery came with a separate charger for use with a mini usb. At first I had problems. The charger would not charge the new battery. I was using a wall connected mini usb to power the charger. So I went to the computer and tried the mini usb from there. It still would not charge. So I took the battery out of the charger and put it into then phone and went back to the wall charger and it was charging. I could feel the phone vibrate and then saw the battery meter slowly fill with green and back to empty and then fill green again.
So I decided to do a few other chores around the house and went to check the charging status after about 10 minutes. I noticed that the phone was on!! I did not turn the phone on. No one else was in the house to turn it on. It was just on. Weird.
So I took the battery out of the phone and decided to try the new charger again with the computer mini USB. It WAS charging this time!! I charged the new battery on this charger using the computer mini USB until the red light(charging) turned green (finished charging) and then put it in the phone. It works fine.
I then decided to put the defective battery into this charger and it was actually charging!! I left it overnight and it was green this morning: identifying it as a full charge.
When the new battery is down to 10% or less I will take it out and put the defective battery in and see what happens.

So I put the original battery back in after the green light came on identifying a full charge on the accessory charger.
It showed 1% and a message came up identifying that "the battery is low, please charge asap", something like that.
So, in my unprofessional opinion , the original battery is toast.
The new battery worked great after its initial charge using the included accessory charger.
When I decided to charge it using the phone itself with the wall charger I noticed some really weird things happening.
First of all you should know that I downloaded and installed Spoon Charge. Look it up here on the forums, free and works great. It basically tells you what charge level you have, temperature of the battery, what voltage is coming in to charge it and also type of charge the battery is doing: trickle, fast, very fast and on battery.You can set it to read reading at specific time intervals: I have it set to read at every second.
I noticed that the charge kept bouncing between very fast and trickle. At one point it went to on battery, then to trickle then to on battery then to fast.
Ok. Weird. . . I thought to myself.
So I let it continue to charge overnight.
The next day I "tried" to use the phone. it was as slow as it was at it's factory installed settings before I did the memory card fix, accelerator settings, and other fixes that I forgot now have forgotten that I have installed.
At this point I decided to drain the battery as fast as I could by turning on WiFi, Bluetooth, and play a movie at the loudest volume possible. As soon as it reached 10% I took the battery out and charged it with the accessory charger. The next morning I saw that the indicator light was green showing full charge and installed the battery in the phone. It booted up and I immediately received a message that the battery was low, saw 1%.
Knowing that this was a BRAND NEW BATTERY, I turned off the phone and took the battery out and waited a few seconds until I put it back in and rebooted the phone.
This time it said 86% charge!!!!!!
WTF!!!!
So I tried to use the phone and it was as sluggish as before. After about 25 minutes it was starting to be a bit faster but nothing like it was before.
I am really confused now. Since I have a new battery I have ruled out that as a problem. So now is it the phone itself? Could it be the wall charger that is faulty?
Any other suggestions would be greatly appreciated.

Another update.
I put the original battery in the phone and now it works!!!! The old battery that would not charge now charges and works!!!
The phone is not the same. Still really slow, can't get it out of the "LOCKED" position when I want to answer a phone call. Opera is sliggish then fast then sluggish. Not what I had the phone at before all of this started. It actually WAS stable. It WAS useable. Now I want to throw it into the drink!!!!!!
Not sure what to think anymore.

well bro go into the system help of ur mobile press as i say
2ce the end button one time call button, 2ce the end button one time call button,one time end button and u will find the problem it is in the charging port the same issue with me

Dell venue pro not turning on?

Hey guys, just wanted to see if anyone else was having this problem, or if possibly my girlfriend has a defective unit. Like i said, my gf has a dvp but when it dies and i connect it to a charger (1 amp) it'll sit for 10-15 minutes and still wont turn on. I was able today to take the battery out, let it sit for a minute, then put it back in and turn it on, and it did just that. And then it showed that the phone was charging. then after a few minutes it turned off.
Anyone else have this problem? Because i know as is, the phone is supposed to turn on automatically because the phone has to be on to charge (a wp7 "feature")
anyone think i have a defective unit? By the way...today when it happened it was the 2nd time its happened to her so far.

It's happened a couple times on mine since I got it in late December.

I am currently having this same problem. This is distinctly different from the other crashes (Marketplace/wifi kindof thing), which is often resolved by quickly removing and replacing the battery, which many are waiting for the April 18 Dell firmware fix to resolve. (Better to hold the power button down for 5 secs than constantly remove the back and battery.)
This is different. The phone is quite dead. The power button is completely unresponsive. The battery must be left out for at least a minute. The phone doesn't even charge when in this state, as I left it on the charger overnight. It does recur as well, but I haven't had time to fully investigate. I have had the nodo update for a week prior to this occuring, so that may not be related.

Having the same problem, and as the guy above stated, THIS IS COMPLETELY DIFFERENT FROM THE NORMAL CRASHES. This has started for me since the NoDo update. Pulling the battery does nothing. I just have to leave it sit and come back. Sometimes it restarts on it's own after 5 minutes and sometimes 2 hours. Either way, I am sick of this lemon.

Same here
Hey i am having the same problem also. I thought it was just because my phone completely died. It turned on eventually and then i had it charging overnight and now its doing the same thing. Seriously thinking about going back to android. So many problems.

I'm having a very similar problem to the one described above. Earlier this evening I unboxed a completely new Dell Venue Pro. It was carrier locked to T-Mobile, but I have subsequently unlocked it with the code provided to me from Dell directly. My plan is to use the phone on the Rogers network in Canada, and right now there is no SIM card in it.
Anyway, the phone refuses to charge properly. When it has the battery in it, and I try plugging it into the wall, the phone shows a full screen icon of a battery with a AC plug on it (I assume this means the phone is fully charged.) However the moment I unplug it the screen goes dark and there is no way of turning it back on. I've tried holding the power button, I've tried pulling the battery, putting it back in, and then holding the power button. Nothing seems to work.
If I plug in the phone into the wall with no battery in it. I can get into the OS. If I then put the battery back into the phone while it is still charging, it'll show that the battery has no charge. After a few minutes (in the ball park of 5-10) it'll again show the full screen icon of a battery with a AC plug on it.
I've compared this to my friend's Samsung Focus which was plugged in when it has no charge. The Samsung focus will show a full screen critically low battery icon when first plugged in, then as it charges we'll get a full screen low battery icon, and then the Windows Phone 7 OS itself will load. (It is still not fully charged, so I do not know if we ultimately get the full screen icon of the battery with plug.)
Both phones (Samsung Focus and Dell Venue Pro) have been charging for over 2 hours now. The Samsung Focus is in the WP7 OS and shows an increasingly charged battery. The Dell Venue Pro still has that full screen battery+plug icon.
The only way I can access the WP7 OS on the Dell Venue Pro is to take out the battery and plug it directly into a wall, or directly into the computer. I have succeeding at carrier unlocking it and upgrading the OS all the way to Mango using this approach. However the phone just refuses to run on battery power.
Has anyone else run into this problem? Do you think it is the phone, or the battery itself? Any advice would be appreciated.
P.S. Sorry to bump such an old thread, but I'm a n00b, and the video said to find a thread related to my problem, and post there.
Edit: So the Samsung Focus finished charging. It lets me interact with the WP7 OS, and does not have the full screen battery with AC plug icon. Although it does have a much smaller version of the icon on the top of the screen where the remaining battery icon is.

Sounds like something my phone did a few months ago. I was able to resolve the issue by following the steps in the post below.
http://forum.xda-developers.com/showpost.php?p=11699369&postcount=10
The issue hasn't happened since. Not sure if it's the same issue but give it a try and see if it helps

THANKS, it worked!
I know I tried those steps (from the same post) before upgrading to Mango and it didn't seem to work. After upgrading to Mango, it did work. The only variation I made to the steps was that when you try to shut down the phone (while holding the power button) I also swiped downward, as that is now needed with Mango.

Hi demondo, im having the same exact problem as you and im also with mango, can you please explain a little better what you did ? Until now nothing had sucess for me
Thanks

Hi Mauriciovsky,
I do not know what the minimum number of steps is to get rid of the problem. Here's what I did, but probably some of it isn't needed:
Charge the phone (with battery in it) using the AC adapter for a few hours with the bettery + plug icon. (I charged it until a Samsung Focus was fully charged.)
Unplug the charger.
Take out the battery.
Plug in phone to computer over USB.
Update the phone all the way to Mango. (You know you're in Mango when holding the back button brings you to the tile view of your running applications.)
With phone still plugged in to USB, plug in the battery.
(MAYBE) unplug the phone from USB. I can't recall if I did this step or now, I don't think so, but maybe.
Either way, turn off the phone. This is done by holding the power button for two seconds and then swiping downward when instructed to do so.
Unplug the phone if you haven't done so earlier.
Hold the power button for two seconds, then let go. The Dell logo should appear, and the phone should boot.
Sorry I can't give you a more concise explanation. However, the phone has been working great in the few hours since the problem went away. Hopefully it'll work for you too.

Hi Mauriciovsky,
I do not know what the minimum number of steps is to get rid of the problem. Here's what I did, but probably some of it isn't needed:
Charge the phone (with battery in it) using the AC adapter for a few hours with the bettery + plug icon. (I charged it until a Samsung Focus was fully charged.)
Unplug the charger.
Take out the battery.
Plug in phone to computer over USB.
Update the phone all the way to Mango. (You know you're in Mango when holding the back button brings you to the tile view of your running applications.)

Thanks a lot for the help demondo and the other guys

I had the same problem: my DVP's, running WP7.5 "Mango", battery got drained and when I tried to turn it back on it would not boot, not even when I hooked it to a power outlet. I finally got it running again, here's what I did:
1. Take out the battery.
2. Turn it on (you should see the Dell logo by now).
3. Put the battery back. (It will alert you that the battery is critically low).
4. Charge it.
*Hope this helps*
