(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.
I've been told that charging the Titan while off is the best way - so the battery resets or something. I don't know if you have to do this everytime or just once and a while.
but i found that I turn my phone off, then while it's charging - it will mysteriously turn itself back on. The battery is not full yet, it just will randomly turn on.
So Is there a way to keep the phone off while charging? (I'm using a wall HTC adapter)
There is no reason to charge with the phone off. Also are you really turning the phone or or putting it in standby.
I hold the power button down till it says 'turn off , yes/no" and I push yes.
by the way what is standby?
push power button to turn phone screen off.
Some winmo phones turn on by itself, the titan and TP are 2.
I use S2U2 to lock the phone so the phone closes itself at a set time.
IMO, turning off your cell phone to charge ruins the point of having a cell phone for the time its off. Even if the phone's off, it'll still be draining a little energy.
Standby:
Phone is on. You press the power button breifly once. Phone screen turns off and phone goes into a low power mode.
Off:
Phone is on. You press and hold the power button and tap Yes when the dialog box asks if you want to turn off the phone. Phone then turns off completely.
If my phone is charging off a PC via USB it will sometimes awake from standby on its own. It doesn't do this when using just a charger. It does not turn on by itself though if fully turned off.
I only turn off my phone to charge if I want it to charge a little bit faster.
Sweet thanks for the replies.
I was just curious. But it turns out that my phone kept turning on, because my charger was on it's way out for some reason.
Tested it and it was only charging at a rate 50mA way less than the 1A label. And it was always super hot. So got a new one, problem solved, glad it didn't fry my phone

what you're referring to is calibrating the battery. to calibrate the battery, you need to charge your phone to 100%, let it die, then charge it to 100% while the phone is off. calibrating your battery resets the sensors inside which provide all the information about your battery, including remaining battery life. definitely a good thing to do every once and a while and you'll notice the difference
There aren't sensors inside the battery.
Hi all !
I have a serious problem when my Galaxy S responses nothing (completely sleep in silence) with any tries to power it on. This happened right after running out of battery, then I plug it to wall for about 1 hour charging, but from that time I can not power it on again (the screen is silently dark).
Please help me to solve this case, and any of your solutions would be highly appreciated.
I would take the battery out for a minute and put it again. Of course plug the powercord out too. Phone should start then.
Sent from my GT-I9000 using XDA App
I have tried such operations :
1. Take battery out; push it in again; then push VOLUMNE DOWN+HOME+ POWER: but nothing is happended.
2. Take battery out; push it in again; then push VOLUMNE UP+HOME+ POWER: but nothing is happended too.
3. Take battery out; push it in again; then push VOLUMNE DOWN+ POWER: but nothing is happended
So, what should i do now ? is my phone bricked after battery drained out ?
My ROM is stock ROM, and I have done LagFix by RyanZ, is there any problem related to the playing Logo at bootime causing it can't be on again ?
Very important: after about 10 minutes taking battery out, push battery again, then plug charger into phone, there is a circular loading symbol appear in one second, then it disappear. Is there anybody know what does this loading symbol mean ?
Had the same problem, simply plug the charger into the mains and your phone. Leave for 15 minutes until the battery thing comes on, then unplug, boot, and charge.
I have done this, but i see nothing when plug-in the charger. No big battery icon at the center of screen as normal. Still unable to turn it on.

Hi! My tablet has no battery, so I put the charger cable and lights flash, but it does it always, lights flash, all turn off and turn on again, and all process again.
I saw somewhere on internet to plugh charger without battery, wait 3 seconds and put battery again. I did that but, when I plug charger without battery it does the same (flash lights, turn off and back to flash light, appear huawei s7 on screen and turn off again). I put battery and nothing happens (still flashing and turn off)
And I can't turn on my device :S
Fault is on the battery... totally drained, and can´t start the charging process.
If you have other battery, test it and see.
If not, find and power supply, and input around 4.3v and 2.0mA... wait for the battery to have at least 3.5 or 3.8v... then I think you can start the normal charge process in the the tablet itself.
I've been sing moto x play for the past 10 months. but recently im facing this issue. my phone switches off at 15% itself. usually itll work till 4% but now it automatically switch off at 15%. any1 else facing this issue? is there any fix for this?

Last month i faced the same issue and this mostly happens when flashing/changing rom or kernel or could also happen when you dont charge your phone above 90℅. The battery stats file needs to be refreshed. Charge your phone to 100℅ and dont unplug it. When it reach 100℅, unplug and plug the power cord in and out a few times (wait a few minutes before unplug again) to make sure it reach 100℅. If everything goes well it will show the correct battery levels again.
Battery Calibration Problem
No need to worry man...this happened with me too..its just a battery calibration problem
If non-rooted
1.Discharge your phone fully until it turns itself off.
2. Turn it on again and let it turn itself off.
3. Plug your phone into a charger and, without turning it on, let it charge until the on-screen or LED indicator says 100 percent.
4. Unplug your charger.
5. Turn your phone on. It's likely that the battery indicator won't say 100 percent, so plug the charger back in (leave your phone on) and continue charging until it says 100 percent on-screen as well.
6. Unplug your phone and restart it. If it doesn't say 100 percent plug the charger back in until it says 100 percent on screen.
7. Repeat this cycle until it says 100 percent (or as close as you think it's going to get) when you start it up without being plugged in.
8. Now, let your battery discharge all the way down to 0 percent and let your phone turn off again.
9. Fully charge the battery one more time without interruption and you should have reset the Android system's battery percentage.
If rooted then just follow these steps:
1. Discharge your phone fully until it turns itself off.
2. Turn it on and let it turn off again.
3. Fully Charge the Switched off phone.
4. Unplug your charger.
5. Turn your phone on. It's likely that the battery indicator won't say 100 percent, so plug the charger back in and continue charging until it says 100 percent on the screen as well.
6. Unplug your phone and restart it. If it doesn't say 100 percent, plug the charger back in until it says 100 percent on screen.
7. You want to repeat this cycle until it says 100 percent (or as close as you think it's going to get) when you start it up without being plugged in.
8. Now, install the Battery Calibration app by IMobS Ltd(Available On PlayStore) and, before you launch it, make sure your battery is at 100 percent again, then restart.
9. Immediately launch the app and Re calibrate your battery.
10. Once you've calibrated your battery, discharge it all the way down to 0 percent and let your phone turn off again.
11. Fully charge the battery one more time without interruption while it's switched off, and the Android system's battery percentage will be reset.

IF above methods doesn't work. Take backup of important files and Reinstall rom
there is a xposwd mod called disablecriticalbatteryshutdown.maybe it will help..
Peace to all
my phone switched itself off once from 60% when I was testing the coffee kernel. I'm not saying the kernel caused it but I reflashed to optimus and never had similar issue.
