(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.
i just got the phone nad first charge i charged it whe ni got it and now its dead im charging it battery is very weak compared to nexus one i had.... but is it true that if u discharge it completley and then charge it completey and repeat 3-4 times battery gets good? i also heard over a little time that battery gets way better? any one can relate to this?
Sounds like you could benefit from re-calibrating your battery. It can be done manually through recovery by resetting battery stats, or easily through an app like this one (you must be rooted).
how u do it without rooted and i heard discharging 3 times and fully charging works? any update on that
There's lots of different "methods" floating around about how to calibrate your battery, many of which actually don't make much sense. The ones that do make sense to me involve deleting the batterystats.bin file. That app TeeJay3800 linked to pretty much does just that. For rooted devices, all the ClockworkMod recoveries have an option to delete battery stats in the Advanced menu.
I think this file is located somewhere in /data but I don't know off the top of my head. I also don't know if root is required to delete this file. Maybe try finding it with Terminal Emulator and attempt to delete it. If that doesnt work, then you'll probably have to root the device (or maybe just temproot it).
yea i did it yesturday nad today its still bad about to attept 3rd charge and im waiting till it dies it went from 39% to 19% within an hour wtf is this??? im waitign till ti dies then recharge to fully
i also did this wthich is good but will it mess anything up if the phone is brand new and is charging fine
Connect the phone to the charger with the phone powered on, and allow the phone to charge until the notification LED is green, indicating the device is fully charged.
Disconnect the phone from the charger, and power it off.
Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the notification LED is green.
Disconnect the phone from the charger and power it on.
Once the phone is powered completely on, power it off again and reconnect it to the charger until the notification LED is green.
Disconnect the phone, power it on, and use it. You need to use this sequence only once.

This is "bump charging" and all it does is try to fill up your battery as much as possible. It's like topping off at the gas station. It won't do much as far as battery calibration. You may see a minor improvement in battery life after a bump charge, but you'll have to do it each time you charge.
Keep in mind that battery life is dependent on many factors, including your usage pattern. Improving battery life is a matter of being mindful and selective about what connections you leave open (bluetooth, GPS, WiFi, account sync) and what apps you let run. Screen usage plays a role as well. Network signal strength also plays a part, but that's not something you can control. Don't use taskillers, they cause more problems than they solve.
I'm assuming you're still on the stock ROM. If that's the case, you should be aware that there's lots of extra stuff on there that runs in the background to support the HTC Sense overlay. The biggest improvement in battery for me was (a) flashing a custom ROM without all that junk on it and (b) flashing a custom kernel which both underclocks the CPU and uses lower voltage settings.
If after all these considerations you still think your battery is borked, head over to a T-Mobile store. They may give just you a new one, otherwise it'll probably cost you not very much.
Hello everyone, I'll tell you the ultimate experience even if it is not the first time that happens.
2 days ago I left the nexus to 46% of battery, the next day I found it turned off and the device would not turn on.
by trying to connect to the power turns on but the display flickers constantly and makes a sound as if he were about to explode.
if I leave a little in office and try to turn it on, it lights up with difficulty and then it shuts down suddenly emitting sound louder and have vertical lines and horizontal time.
I'll post a video to make you understand better.
the problem is not to download the battery or something more serious?
sorry for my enghlis, it's made by google!
video:
https://www.youtube.com/watch?v=HLmB8oYIZDQ&list=UUzN7W_39t1nVjuznllixPIg&index=1
If you leave it plugged in and don't touch it for a while, does it eventually do anything? Just sounds like the battery is dead to me, although not sure about the weirdness with screen etc.
Leave it plugged in for a while on the original charger/cable and if it doesn't boot up right after 30-60 minutes of charging, you might have to warranty exchange it.
if I leave the tablet plugged into the power outlet for a few minutes (maybe 10) everything is back to normal.
the strange thing is that this problem occurs when the battery drops below 20%

Good to hear! My guess is that it didn't have enough power to really power on, which I don't like in various ways.. First it might mean the battery was overly discharged (when your battery is at 0%, it's still well above minimum LiPoly minimum voltage, but I question that in your case for example) or that something else is kooky.
I'd say charge it to 100% and use it normally, and let it get down to 5-10%, lower if you like... If it continues to behave okay, maybe just a fluke. If it freaks out below 15% or something, warranty it.
After watching that video I would say return it. That looks bad man! Also, what is on the end of your power cable? Looks like a piece of wire or tape or something?

Hello everyone my brother's Ph-1 keeps shutting down right after powering up, I have tried everything from factory resetting to trying a different charger, nothing seems to work. This happened after he didn't use the phone for almost a month, it worked perfectly before.
It powers off even when on charge or connected to the laptop.
The phone doesn't stay on for more than a minute or two which means i cannot use ADB to side load an update
The phone is running Android P and the April security update patch.
Please do help me out
Thanking you

It could be corrupted though it sounds a bit like a battery issue, to me. If battery discharges too much eg it didn't shut down itself properly when battery was at a low level (they retain more charge than shown to user so it can shut down with proper procedure) & the battery ran down past it's reserve the battery may not be able to be recharged with a normal charger even though you charge it. (Thought a battery specialist could possibly revive it with a boost charge, though I've only seen these used with industrial batteries)
with a "dead battery bootloop" sometimes you can get it going by booting when connected to the charger, but you'll probably need a new battery. Maybe also try boot into safe or recovery mode when connected to Essential charger. (I'm assuming your phone not corrupted, though as you haven't given us much info about exactly what happens & what you are seeing)

The phone shuts down even when in recovery or safe mode whilst connected to the charger.
It does sometimes fully boot up and then shutdowns, but mostly shuts down while still on the essential logo.
If I may ask what do you mean by the phone might be corrupt?
Can one month of non usage cause the battery to die out?

The phone shuts down even when in recovery or safe mode whilst connected to the charger.
It does sometimes fully boot up and then shutdowns, but mostly shuts down while still on the essential logo.
If I may ask what do you mean by the phone might be corrupt?

by corrupt I mean some data that is part of the boot process causes bootloop so it shuts down, but as your phone is shutting down at different points in boot cycle I think it's probably battery
Leaving the phone turned off unused for longish periods should not be a problem normally even with a few % left in battery. And even if left turned on it should shut itself down when battery low & be able to boot up again after a month due to the battery "reserve" capacity (but possibly a month was too long). And if it was not recharged straight away and/or rebooted multiple times the battery "reserve" could fall too low and not have enough power to start/shutdown properly (possibly causing data corruption ... though l don't know if there is some sort of fail-safe boot procedure ) Then there is a possibility there is a hardware fault with battery/phone that meant battery lost too much power.
There were some tricks ie "boost charge" you could do with removable batteries that were in "deep sleep" as shown here for example

But they don't really work without taking your battery out (for us we might as well get a new battery when opening phone up, & there would be some risk that you damage battery as we do not know the exact charge to apply on this battery, which could cause unsafe battery) I wouldn't want to freeze my phone even though it should survive OK, as I'd be alittle concerned about long term effect on our screens small pixels (I remember the guys at popular mechanics put an old flip phone with little LCD screen in liquid nitrogen & it still worked after being warmed up!).

firmware issues do not cause the issue you are describing
you have a hardware problem
sounds like a bad battery to me
good news is the battery is not difficult to replace (don't listen to ifixit I am not sure what they where smoking when they did there tear down)

don't bother with silly and wrong tricks like trying to hack the battery back to life its the wrong way todo
if the battery ever gets to that point then the battery is bad enough said

So true! )) As much as I respect the guys from iFixit, they screwed this one up pretty badly - basically, made a tutorial on how to destroy your phone. Fixez.com did much better.
