(Bare with me, this IS wm6 related)
Okay, so i got this qtek 9090 from a trade online, and the owner pointed out that he had used it for some time now and it worked without problems.
However that seems not to be my experience. At first I was a little worried that it did not came with a charger.. Only a USB cable. No worries i thought, I will just charge it through USB. Now I have had some experiences where phones wouldn't charge from some of my computers, apparently because of some boards that put out lower amps than others. However I knew atleast one computer should have no problem charge ordinary cell phones.
So i plugged it in, and to my worries the battery kept going down... Untill the phone was dried from power and everything got lost again.. and again.. and again.. It seemed a little odd that it apparently deleted everything each time, since the backup battery indicated 100%.
So at last it went into flightmode and I shut it down with the powerbutton and let it be connected.. The first many hours nothing happened.. But suddenly, when i did an occasional check, it said 3% battery. I went to sleep and the next morning it was fully charged. I used it all day in school and it held its power real fine.
Now I got the feeling that this probably was caused by the low amp output from the computer, making it unable of charging to the extend where the phone would still be able of running whilst charging. So i figured i would order a 220v (the powercurrent here in Denmark) -> 5v USB that outputs 700mA, to make a quicker charge.
Well, to day I was gonna receive that adapter, and since I'd read that the wm6 apparently draines the battery some bit, I waited untill today to upgrade to wm6.
I upgraded and everything truely runs quick and stable. But when i recieved the adapter and plugged it in, i was horrified. The power kept going down, as I had experienced when it was plugged into USB.
Now my girlfriend really wanted to play bejeweled on this thing, so she did and then shortly afterwards we took a few hours nap. I had her plug it in the new adapter to charge it. When i woke up i saw the screen blinking.
I could se it was rebooting over and over again, as it had done the first time it completely lost power..
Now besides that extremely annoying charging problem, I now had another concern....
The boot screen shows NONE next to the R and the G.
Next to the D is the wm version displayed.
Any help would be greatly appreciated.
red LED?
Hm.. By doing a hard reset it shows numbers next to R and G again.
It continuely reboots, display boot screen, shuts down, LED is red, reboots, displays boot screen, shuts down, LED is red again and again.
If i hard reset it some times it will at one point stay off, but the LED still lights red.
And now I question wether 700mA is even enough for charging the BA?
1. Higher power given by power supply does not mean, you will get faster charging
2. If you use WM5/WM6 and have Bluetooth turned on, device turns on every few minutes (bug/feature of the driver needed to keep Bluetooth running: look for BigMike's fix for more information). If your deivce is set up to turn off after long time (for ex. 5 mins), battery might drain out in half a day.
3. Check power settings (delays for device power down etc.)
4. In WM6 be sure, that audio manager is not running (prevents device from deep sleep, allows only screen shutdown)
5. If battery shows up 100% and after disconnecting device discharges in less than 2h being turned on all the time (wifi, bt, phone, screen all the time turned on) it means, that battery might be worn. Consider exchange.
R and G showing NONE is normal in WM5/WM6 because of bug (unfixable for now) in the device and it's incomatibility with this OS: after turning on from power down (taking battery out or total discharging) make soft reset just when R NONE G NONE shows up on the screen. Everything will be normal.

AFAIK the lower the mA output, the slower the charge period.
I have had wifi, bluetooth, beam off. I've set shutdown to 2 minutes. I've set it to low brightness and etc.
As i mentioned it had no problems going a whole day of usage in school.
Didn't know about the bug in wm6 that makes only the screen shut off, but at the momemt i can't even boot the device, apparently because it has no batterypower. And having it connected to the charger makes no real difference (other than it will display the bootscreen and perhaps even the Windows Mobile welcome screen thing, for a few seconds.. then go dead again.)
I've had it in the charger for about an hour or two, still not enough power to boot it up.
It feels like it's just not charging sometimes.. And other times it will charge just fine.
Found out about the reset to solve the NONE issue, but i still don't know what it means that its LED is red all the time?
Even 500mA is enough for sure, as charging from USB works fine.
Device will shut down soon after turning on if there is not enough power in battery, even it if is charging. Leave it charging (amber led on the right) for some time. RED led means low battery and no charging (AFAIR).

This is not a bug - thanks to this you can still listen to your music keeping device with screen turned off, when you don't need it to spare battery.

Red LED (right one) means low battery, no charging. To charge this led must be amber. Details - you must look for manual.

Okay.
It's odd still. When i connect the charger the right LED starts to light red.
If it means that its not charging, there must be something wrong, since it only happens when connecting the charger..
it can be amber or red. Those are different colors and meaning.
You can confirm it charges touching the battery - it becomes slightly warm after some time.

I KNOW that, but it is not going amber. It stays red all the time.
Found this thread that discusses a similar problem; http://forum.xda-developers.com/archive/index.php/t-233782.html
Apparently it shows RED light all the time if the battery is dead.. However i hardly doubt that the battery, which could power the phone just fine for and entire day, should be dead.
However, one suggestion in the thread was to take out the battery for some time and then try again. So I will do that for now.
Behavior has changed a bit now..
The LED is still red when i connect the charger. However, if i try to turn it on following happens:
Boot Screen shows for a couple of seconds...
Windows Mobile startup screen appears and the LED changes to orange/amber..
After a few seconds the screen turns black and the LED changes to red again...
And then after a few more seconds the boot screen appears again and everything is repeated, over and over.
If I disconnect the charger the boot screen appears, the wm startup screen appears, this time with a flashing red LED.. shortly after the phone turns off.

I've seen this problem before. The charger is not putting out enough power to both charge and boot the BA. So what happens is that it starts charging enough to start boot, but as soon as it has enough power to start the boot, it immediately drains it by starting to boot with screen at full brightness.
What I do in this case is to try to catch it just as it starts to boot and turn the backlight off by holding down the power button for 5 sec. This turns off the backlight so there is less drain and the thing can boot up and start charging.
All in all, its a pretty stupid bug but what the hell, there is a solution to it.
Good luck.

This seems to work atm. (just a few seconds since it successfully booted)..
Does this mean that the device really cant charge if its not "on" ?
(I can see its booted and the LED is now orange. If only it will stay this way untill it has been recharged further ))

It can charge when it is off. BUT... When its off, its not really off... It has to finish booting and then you can turn it off. Then it will charge faster as it only has minimum drain on the battery. As I said before, its a stupid design.

Well we can certainly agree on that
So does the phone also basicly use to much power to be used and charged at the same time? Which would explain why it seemed to lose power even though it was connected to the charger.
Although it still doesn't add up for me, as at one point i was playing a game on it, while charging and then it charged real fast, where you would expect it to use more power
Oh well, if only it keeps charging now i'll be glad

I have found that if you only use the USB cable to charge, it takes much longer (if at all) to charge if it is on. Thats why I bought cradles that have external power suppies as well as the USB sync cable. With this configuration, it gets to full charge in about 90 minutes.
Hm.. yeah.. I let it charge for some time, until it shut down and the LED changed to red again.. The same thing has happened about 3 times now.. If I try to navigate it with the brightness off it will shut down after a few clicks..
Seems like either the battery is completely dead or it's simply not charging.. :/
Think i have to buy a new battery and a cradle, although i didn't really want to spend money on this phone as i got it virtually for free (through a trade of a w810i)

Get it to orange and then push the power button (short push) to turn it off (not long push which only turns off the backlight). Then let it charge for an hour or 2 (or even all night). By then, it should work OK.

Yeah, i tried that. As soon as i press the power button it goes to red again.
Update..
A litte update (i might as well document everything I find out here, if anyone should run into a similar problem).
Now, I've had the device connected to the charge for some time now.
What happens is that the device boots up, automaticly dimms down to no light (since i once had hold down the power button, to dimm down light).
Then it boots up, and i can see everything running.
I can navigate to the battery status menu, which shows
Battery: 0% (charging)
Backup battery: 25%
After a few minutes the device shuts down, and the LED goes red again. But after about a half a minute it will try to boot up again, and it goes through everything again.
What I've noticed is that the backup battery slowly increases, and while im writing it has gone all the way to 75%. The good thing about this completely automatic procedure is that it apparently slowly charges, at least, the backup battery.
My theory is that the backup battery has first priority in the system, so that the regular battery wont charge untill the backup battery is up. And since the backup battery can't apparently be used for actualy powering the system, the system will continuesly reboot because of lack of power, theoreticly untill the backup battery reaches 100% and it starts to charge the regular battery.
The whole problem seems to be cause by some charging malfunction, so that both batteries has been completely discharged. I hope that by letting it continue to reboot, charge, reboot, charge, etc. it will revive the battery.
I will return with more info tomorrow.
Any suggestions are still greatly appreciated.
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.
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

Not everything my friend
Just charge the battery for some HOURS or over the night. All the described symptoms indicate a low battery to me.
cheers
UPDATE:
Just managed to unlock a bootloader in that short period of time i can get to fastboot. But still no change, phone wont stay in fastboot.

Well, i actaully tried to leave it plugged over night. But i think it stops charging right after the red light dissapears, which happens after 15mins or so after plugging. Btw, i mentioned earlier that battery shows 3.7V when measured with multimeter, so the battery doesn't seem to be the culprit... or does it...?

your battery is drained below safe line....to 0%. They warn you NOT to update it with less than 60% battery FOR A REASON!!
Friends case she managed to charge ger asus 7 memopad with non-removable bat to 60% after 8 HOURS, because of a bloatware wakelock drainage to 0% after a factory reset....
If that doesn't work you have to either recharge the battery manually (something like car batteries, you have to unsolder the battery connector because the battery doesnt have 2 gold squares that touch the gold pins like the removable ones, or get a new battery.
Li-Po batteries should never be discharged to 0%, and can make problems if they are not removable (Nexus 4)

If that doesn't work you have to either recharge the battery manually (something like car batteries, you have to unsolder the battery connector because the battery doesnt have 2 gold squares that touch the gold pins like the removable ones, or get a new battery.
Li-Po batteries should never be discharged to 0%, and can make problems if they are not removable (Nexus 4)

I did manage to charge it manually with two small wires and an old Nokia charger, when checking battery with multimeter after a few minutes of charging seems to increase voltage. But i guess if the chip on battery is fried there is nothing more i can do.
I will try to leave the phone on charger all night once again, see if that makes a difference, and update if anything changes.
take off the back, disconnect the battery connector wire and connect it again, put it on charger and see if things change
UPDATE:
Leaving it to charge overnight didn't have any effect. Any other suggestions than changing a battery?
Nah, sorry, but i am out of ideas. You basically tried it all :/

I know there is a lot of threads about bricked N4's, and i can assure you that I have viewed each and every one of them, but i still can't resolve my broblem.
This whole brick situation happened after trying to update to Android 4.3 OTA update, the phone didn't complete the process and turned off, where red light of death happened.
So the scenario goes like this:
If i hold POWER button for ~30s when phone is off charger i only get a Google logo for 2 sec, and phone instantly restarts
Holding PWR+VOL-DOWN buttons when phone is off charger doesn't do anything
Plugging phone to charge (socket or PC) results in solid red light
Holding PWR+VOL-DOWN or PWR+VOL-DOWN+VOL-UP for ~15s makes the red light blink at a steady rate
While continuing to hold the respective buttons and pluging the charger off, and on again gets me to bootloader or download mode (depending on button combo) for ~2s and phone restarts.
I tried removing and inserting the battery 3 times. One time i got blinking red light when plugged the charger in. Second time i got solid red light and third time got solid red light again
I tried charging the battery directly for 15 minutes with old Nokia charger, and it resulted in something different(when i assembled the phone and tried to turn it on with PWR+VOL-DOWN buttons when charger was plugged off, i got to bootloader for 2seconds before phone restarted, i tried to boot second time and the same thing happened, but when i tried it third time i got nothing, just like before) so this was the first time i got into bootloader while not charging a phone.
*My PC seems to pick up the phone for a brief moment when it is in bootloader and starts installing the drivers. Drivers gets installed when i'm in download mode for that brief moment too.
**Phone doesn't get to the white or red battery icon while plugged to charge.
***Solid red light dissapears after charging for ~10mins, but phone won't do anything.
****When measured with a multimeter battery shows 3.7V
I hope someone will be able to help me with this, as it is frustrating as f*ck. I don't have a working warranty, so fixing the N4 isn't an option, and where i live phone repair prices are over the roof (ex. motherboard change for N4 costs ~270$ ).

I had the same problem. Kept it on the charger for a whole day and still only the Red Light.
Took it to a local shop and they said there is a short circuit in the antenna
Took it to the LG Service center and they said my motherboard is gone.
Both were costing a bomb to repair and still there was no guarantee.
IMHO, get a new phone.
Sorry
Have you tried charging it with a wireless charging pad? I got mine to boot after I did that. Your battery is drained and it doesn't have enough juice to charge itself.

Don't fall for the motherboard dead trick. Just a way to steal your money.... change the battery and never let it go to 1%
