(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.
Sorry for the bad english.
I had my xperia for like 2 weeks now and last night i plug the usb from the
computer to my phone and my phone just completely shuts off. there is a red
light once in a while when its being charged. i charged it for 6 hours now and
it still won't turn on!??! Somehow my phone vibrates ones every two minutes
when it is off or being charged...have and idea??
are you still charging from the computer or the wall outlet. if not doing so already, i recommend that you charge from the wall outlet instead of the computers usb.
it may take a while before the red light goes out. turn off the phone and recharge it overnight.
i'm charging it from the wall outlet. The red light doesnt turn on anymore.
and still i can't turn on my phone.
1. Remove the battery cover.
2. Remove the stylus.
3. Use your stylus to press in the small RESET hole which is along the slot where you just took your stylus out of. you will feel something click in as you press it, like a hidden button.
if that does't help, take out the battery and put it back in after a second or two or three. hehe.
then connect it to the wall charger.
I had this problem a few days ago... it didn't switch on even after a whole night's charge
you just have take the battery out, then put the usb cable in, then put the battery in... you'll notice the red light doesn't flash anymore... BUT!! don't try to switch on... i'd leave it for around 1 minute, before switching it back on. if you just leave it; the red light will start flashing again
WB,

I tried all of the following and it still doesnt work.
i put the usb cable in and it pops up the red light and my computer says it doesnt recognize the device. and my phone vibrates happends every 1 min or so..
but it still won't turn on
no, plug the usb cable directly into the power point. it's useless using a computer to charge the phone anyway, it doesn't supply enough power. just keep trying different combinations... mine ended up working after what i said before, although i did use the car charger in may car as after the charge in the night didn't work.
1 - take out battery
2 - insert usb cable to phone and power point
3 - insert battery
4 - wait 30 secs to 1 minute
5 - press power button for like 4 secs...
man this sucks i did that too and its still not working...
hmm i don't know what happen to it. it was still full battery when it suddenly
shuts down. could it be the battery?
tried manually booting SPL??? hold volume down button and press power and keep holding for 3-4 seconds..... see if that works
i did that too still no sign.
i know its not dead cause when charge it the phone vibrates every 1 min or so
and it stops after maybe 5 mins
I have problems with charging my X1 with my PC.
My X1 only charges when my PC is turned on, with my Elf (HTC Touch) it charges also when my PC was turned off.
So I thought X1 would charge too, when my PC is turned off.
But it seems it drains the battery out of my X1 :-s
So next morning, my X1's battery was empty (after 3 hrs charging on USB => then it was full, and let it connected with my pc in the night, when pc is turned off.
It was quite frustrating for me, but I really don't know why this happens to X1 and not with my Elf.
try taking out the battery, wait 5 mins, re- insert it.
Then start charging via wall socket. wait 5 mins again and then breifly press the power button, should vibrate once then turn on.
I´m on Paranoid Android, last version. I was whaching a movie with less than 4% battery, and It powered off. Problem is that It doesn´t boot and It doesn´t charge either.
Please please Help!!!
Sorry for my english
Hopefully your up by now after letting the device charge for a while. If not I'll throw this fix out in case it's a software problem. I have no idea, but: The Nexus 7 has a similar situation of not accepting charge after the battery runs dead. Maybe the same fix will work? With the charger plugged in, hold your power/vol button combo to boot into bootloader/recovery. From there select power off. Then the tablet "should" accept charge. It's the first idea I thought of, but I thought that was an Asus problem.

The problem is that you can´t boot into bootloader/recovery. Tablet doesn´t respond. When charger plugged in, It shows icon of battery when pressing power button but it dissappears in a second....
Hold power button 15-20 seconds until it vibrates & release. If no boot then, unplug and try it. I had this problem once also. Mine finally booted when unplugged for some reason (after being on a wall charger for a couple hours). Someone told me during my ordeal to first plug into a computer for the 1st hour, then go to the wall charger. I think holding until vibrate was the key for me, or so it seemed.

It seems to be charger´s fault. I can confirm it in one hour...

Ok my n10 is rooted and romed with CARBON rom, no problems nothing, but today I had an email come in I looked at it set It down left the screen on a second later it just died. so I plugged it in back on it comes. later same thing almost dead checked new email, set it down screen on then death.....plugged it in again, now nothing except a flashing battery charging symbol. been charging for 10 min. tried power, power volume down, nothing....got a different cable...nothing.....my computer wont pick it up either. what do I do?????
PLEASE HELP!!!
I just had this same problem with mine; because of the strange battery issue where my battery would read 90% when it was actually empty and slow charging once it was plugged in... The resolution for me was to plug it into the charger for 5 minutes and not touch it and then try a power on.

Thanks Ill give it a go!!
Plug it in to the wall charger, not a computer. Let it sit for 30 minutes and then hold all buttons down at the same time. This should let the tablet boot now and will bring you into fastboot mode. It defaults to "Start" so just hit the power button and the tablet will boot like normal. Once you verify the tablet will boot fine, shut it down and leave it plugged into the wall charger until the tablet is charged all the way.
Dont know if it is a coincidence or not but this is the 3rd time I have heard the same story and all people were using the Carbon ROM.
Thanks guys for the feedback, definitely will be switching roms and buy the pogo charger!

I don't know how many people are still using these, but I have a solution to this that doesn't involve opening up the tablet or anything else invasive.
The problem is that the screen stays on and drains the battery too quickly before android has a chance to fully boot, so it dies and then starts up again. So you want to let it charge as much as possible with the screen off, before finally letting it boot.
The way I do this is to plug the tablet into my laptop (for whatever reason this technique doesn't work with the wall charger), and then hold the power button down for like 5 minutes. Don't let go of the power button, just hold it down.
After the initial 30 seconds, the tablet will go into a boot loop of having the display on for about 2 seconds, and then off for about 10 seconds. The battery is charging during that 10 seconds, and the 2 seconds of display time isn't enough to fully drain it. Just keep holding that power button. After 5 or so minutes of this, once the display comes on just let the power button go. It should boot up completely into android and dim the screen (but hit the power button to turn off the display once it's fully booted up, just in case).
Android should now be slowly charging, and the lock screen will say it's at 0% or 1% and charging slowly. Just leave it alone and it will fully charge. After a minute it's usually got enough power to quickly switch from the laptop charger to the wall charger, if that's your preferred charging method.
