(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.
Hi everyone, yesterday I took my G1 from my pocket (after using it normally for some hours) and it was turned off. I thought the battery was dead (I left it at about 20% charge) so I tried to turn it back on and surprise...no vital signs at all. The phone didn't turn on, and the led was dead. After losing half of my hair, I tried removing the battery and placing it back. Now the phone behaves like this; when I press the power button, as long as I keep it pressed the led flashes red and that's it. When I stop pressing the power button the led stops flashing. When I plug the usb cable, the led gives a solid red and stays like that forever.
Please someone tell me it's just a screwed up battery...please

Probably bad battery. It is certainly worth it to at least try another battery -- they're dirt cheap anyways, or better yet, BORROW one.
* Solid green (when connected to the power adapter): The battery is fully charged.
* Solid red (when connected to the power adapter): The battery is charging.
* Flashing red: The battery is low and needs to be charged.
* Flashing green: There is a new notification.

Leave it to charge for 30 minutes or so, then try to power on. should be okay
better to charge from ac power if u can
Its possible your charger could be faulty.
I have the same problem, has anyone found a solution?
Try leaving it charge for a good hour, or just go out and try a new battery, could just be dead.
Sent from my Xoom
sometimes if a battery gets to low it wont even charge... not just for phones but cameras too and so on..... iv had to do this to cell phones and cameras.... take a usb cord you dont care about and cut it and expose the red and black wires..... look for the positive on your battery and negative, usually its marked, how positive to positive and negative to negative for 30 seconds to a minute while its plugged into the computer then, pop the battery back into the phone and try to charge..... everytime iv had to do this for a freind or something of my own the battery has lasted over a year after with no problems.... just a suggestion
Thanks for the suggestions. I had already ordered a new battery and the phone boots up with it but it won't charge on or off and usb isn't recognized either. I tried wiggling the plug around to see if it was some kind of loose connection but it doesn't appear to be the case. I may take the phone apart and see if anything is loose but otherwise I'll just have to enjoy the last 30% battery of G1 time I have.
Found this on Desire Android Development forum ... http://forum.xda-developers.com/showthread.php?t=755903 ... MOD Edit: Link created.
Found this on another forum, I have done this a few times myself (do it whenever i flash a new rom because i always clear battery stats, can't hurt). Have found that it does top it up a fair bit. Before doing this i find my desire will drop to +-93% straight off the charger, however this keeps it 100% longer and i actually get to see the numbers 99-94%
Worth a go in my opinion because it only takes 5 mins of your time and can't hurt the phone... So any minor gain from this process is a win...
Hi *******, I understand your concern regarding battery life on your Nexus One device. The following steps should significantly extend the battery life on your phone. Please 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. If the issue of battery life on our phone persists, I recommend you contact our HTC accessory department directly.

From what I have read on there forums the whole procedure should go like this :
So combining the two bits of info we've compiled, the best way to calibrate your battery is as follows
1: Charge phone whilst on till LED is green.
2: Disconnect phone from charger, power it off.
3: Reconnect to charger with phone powered off and allow to charge till LED is green.
4: Disconnect the phone from charger, power it on. Once completely powered on, turn it off again and reconnect to charger until LED is green.
5: Reboot into recovery (back button held at same time as power button) and wipe battery stats.
Battery should now be calibrated.

So I am trying this right now as I type this but the problem I am running into is I charged my phone to full - green led . Problem comes when I power off phone and plug charger back in the phone automaticly boots into Clockwork Recovery ( Thats with the stock charger plugged into a wall socket not computer ) I tried to charge phone that way but led never turns green so I charged it all night that way. Powered phone back on fully , then turned off and charged again in clockwork recovery led never turning green . Cleared batt data in clockwork recovery and powered on . Battery life is unimproved drains fast if not faster than before lol . Hope someone can help . Main problem being how do I get phone to charge with power off and not booting into clockwork recovery when charger plugged in.
Now I have read else where
It seems the old battery icon was part of the original recovery, so there is no fix is on the horizon. Really, no functionality has been lost. The phone is never really off when charging anyway. Better to just leave the phone on and let the screen go off while charging.

HTC Aria - Unrevoked3 Root Method - Attn1's ROM: Liberated_Aria_b005
Hope I made sense I am noob to all this
Ok so here is what I am doing right now - My Calibration Breakdown
1: Did cjperone's !!!!Battery Saver Fix? hit fix permissions in ROM Manager app ( Don't know if this is needed but said what the hell go for the gusto )
2: Rebooted phone per ROM manager app telling me to
3: Charge phone while on till LED is green. Battery was at 4137v ( From what I have read 4137v is opptimal full charge )
4: Disconnect phone from charger, power it off.
5: Reconnect to charger with phone in Clockwork Recovery and allowed to charge for 4 hours . (Since Led Will Not Turn Green )
6: Disconnect the phone from charger, power it on. Once completely powered on, turn it off again and reconnect to charger with phone in Clockwork Recovery and allowed to charge for 4 hours . (Since Led Will Not Turn Green )
7: Since I was already in Clockwork Recovery I wiped battery stats and rebooted phone.
I will use my phone normally today and will see what happens. I will post back results later on tonight.
Well first try not so good with method above I rebooted my phone and within 30 minutes of normal use charge was already at 86% honestly I think froyo 2.2 has a lott too do with the results people are getting. So I installed the newest version for the aria on the forums and gonna try again. I'll keep you updated.

if u did a nandroid from the beginning before u rooted ur phone u can do the original method then flash ur most recent nandroidd back up
Hi mate, glad to run across your post I was wondering what was up too. I have the same setup, but so far mine charges in a normal off status but still doesn't hit green. If I turn it on it is at 100% but not for long. It's definitely draining quicker than the 2.1 setup I had before. Not sure what to do exactly.
Update4: (14.01.2012 1244): This method didn't work. I sent my Defy back to Amazon and they repaired it under warranty
They will send it back to me next week. It seems that it was a production failure.
Anyway, thank you very much for your help cengiran!
Hi Guys!
I do have a big problem with my Defy.
I updated the CM9 onto the newest version and had to activate my google-acc. I didnt finish the smartphone registration and put my Defy to the side. Today morning the battery was empty and I reloaded the battery. After that I turned the device on but the only thing it shows is a black screen with stripes (even in cwm and bootloader). Does anyone know how to fix my Defy??? The Defy boots completely but the screen remains crappy ;(
Please help me!!!
With best regards
HT
Edit1: (27.12. 1421): New day, same problem ;( Still found nothing helpful...
Update: (27.12. 1736): Flashed a new fixed sbf with RSD Lite. Still the same problem. Could it be a hardware problem??? LCD-Display broken or stuff like that? Didnt throw the phone through the room like others (^^);
Update2: (29.12. 0801): Error still remains... Is their anyone who had the same problem or who can help me? Do I have to replace my Defy? Might there be problems with Amazon (warranty) because of root and stuff like that?
Update3: (30.12. 2217): Now trying the tip by cengiran:

hi there,
i have the same issue but not due to CM9 installation but due to hardware issue. judging by your writing, this has nothing to do with software and so hopefully this helps.
My screen is also black at boot with some part of it are stripes (and some bad white and blue square w/ noise) and looks like a broken LCD monitor.
This is due to hardware malfunction (probably your battery went bad) in my defy the battery have some water damage and somehow it screws up the voltage regulator or the grounding part, but does boot with the correct screen using some techniques on every boot.
Try this solutions:
1. completely discharge your battery, take it off, hold the phone power button for 30 seconds to make sure every power stored in phone is out. Put the battery back on and connect the charger while the phone is still off. DO NOT turn the phone on. Your screen will look all mess up when showing the green battery, wait until 3hours and take a look at your screen again. In my case, the screen showing the the battery charging image is clear again after i did this. - this is to make sure that your screen is actually okay. Try turning your phone now and see...if its still bad then go to step 2.
2. turn phone off, open the battery case. Connect phone to charger again without turning it on. The phone will do its regular boot up until showing you the battery icon again. when the battery icon is there, PULL the BATTERY out of the phone (the charger cable is still connected to the phone). the phone will reboot itself with the correct screen usually, if it doesnt boot itself, quickly pull charger cable and reconect it again (with the battery still detached from your phone).
mind you if you get to the okay screen, this will not boot your phone, this will bring you as far to the battery icon with a question mark (we know for sure is just battery issue now). regardless screen is okay or not, proceed to step 3.
3. turn off phone, battery out of the phone, and press the power button for 30 seconds. release power button and re-insert battery and boot. (usually still bad but this is to ground any left voltage in there). after it boots (with the bad screen, if the screen is okay then proceed to using your phone like usual) before the LED lights blinks (the 2nd.init lights) pull out battery, press the power button for 2 seconds, re- insert, and boot. repeat this as necessary until it boots with an okay screen.
tips:
battery empty is for step 1 only, steps 2 and 3 needs power form the battery.
You can actually go to step 3 if you wishes, but my experience is by using step 2, it will talke less retry until i boot with the okay screen (i need to do this everytime i restart the phone mind you, so its a daily thing) .
the LAST tip: there no rules of thumb on how many retries it needs, if you have been retrying for 20 minutes on step 3 with no avail, revert back to step 1 or 2 and retry step 3. If this is sill fails, then you might need to consider purchasing a new battery, or take it for a repair!
Im still waiting for my new battery, but now it only takes me 5-6 tries before it boots correctly, in the apst it took me 15 minutes of constantly retrying so be patient, but still need to set a line when to give up!
Hope this helps and good luck
how does it go?
to completely discharge your battery is tricky...and actually not recommended because i heard our kind of battery should never went completely gone, it can mess up the battery capacity. i suggested it because thays what i did and in this case, battery cost much less then actual repair,,call it collateral if you will.
heres what i did to completly discharge it...after the phonse turned off automatically due to battery running out, it still have around 2% in it so reboot and enter 2ndinit/boot loader. let it stay there until the phone turned off on its own again. in 2nd init, the phone wont turn off screen so it will continue using whatever is left in the battery. keep n mind that even at very small amount of juice left, this process can takes up 2hrs or more.

Your screen will look all mess up when showing the green battery, wait until 3hours and take a look at your screen again. In my case, the screen showing the the battery charging image is clear again after i did this. - this is to make sure that your screen is actually okay. Try turning your phone now and see...if its still bad then go to step 2.
2. turn phone off, open the battery case. Connect phone to charger again without turning it on. The phone will do its regular boot up until showing you the battery icon again. when the battery icon is there, PULL the BATTERY out of the phone (the charger cable is still connected to the phone). the phone will reboot itself with the correct screen usually, if it doesnt boot itself, quickly pull charger cable and reconect it again (with the battery still detached from your phone).
mind you if you get to the okay screen, this will not boot your phone, this will bring you as far to the battery icon with a question mark (we know for sure is just battery issue now). regardless screen is okay or not, proceed to step 3.
3. turn off phone, battery out of the phone, and press the power button for 30 seconds. release power button and re-insert battery and boot. (usually still bad but this is to ground any left voltage in there). after it boots (with the bad screen, if the screen is okay then proceed to using your phone like usual) before the LED lights blinks (the 2nd.init lights) pull out battery, press the power button for 2 seconds, re- insert, and boot. repeat this as necessary until it boots with an okay screen.
tips:
battery empty is for step 1 only, steps 2 and 3 needs power form the battery.
You can actually go to step 3 if you wishes, but my experience is by using step 2, it will talke less retry until i boot with the okay screen (i need to do this everytime i restart the phone mind you, so its a daily thing) .
the LAST tip: there no rules of thumb on how many retries it needs, if you have been retrying for 20 minutes on step 3 with no avail, revert back to step 1 or 2 and retry step 3. If this is sill fails, then you might need to consider purchasing a new battery, or take it for a repair!
Im still waiting for my new battery, but now it only takes me 5-6 tries before it boots correctly, in the apst it took me 15 minutes of constantly retrying so be patient, but still need to set a line when to give up!
Hope this helps and good luck
Hi cengiran,
thank you very much for your help. I will try this immediately. The only problem I do have that my battery doesn't want to go empty XD
There are so many people who want their battery to last as long as possible and now I want to get it empty a quick as possible XD Irony
Since 26th December 1004 pm my Defy runs with one single battery charge XD I think thats a pretty good battery life for a smartphone ;D
If your tips don't work I will sent it back to Amazon and hopefully they send me a new one or repair my old one.
Thanks again and I will post if your method works.
With best regards
HT
P.S. Amazing that this thread is the 1st Google search result for this problem XD
how does it go?
to completely discharge your battery is tricky...and actually not recommended because i heard our kind of battery should never went completely gone, it can mess up the battery capacity. i suggested it because thays what i did and in this case, battery cost much less then actual repair,,call it collateral if you will.
heres what i did to completly discharge it...after the phonse turned off automatically due to battery running out, it still have around 2% in it so reboot and enter 2ndinit/boot loader. let it stay there until the phone turned off on its own again. in 2nd init, the phone wont turn off screen so it will continue using whatever is left in the battery. keep n mind that even at very small amount of juice left, this process can takes up 2hrs or more.
Finally! My battery is empty
Now I try your method and see what happens
This method didn't work. I sent my Defy back to Amazon and they repaired it under warranty
They will send it back to me next week. It seems that it was a production failure.
Thanks anyway!
With best regards

Thanks a lot, a mix of these two works for me !
My problem arise after a month that I switched off defy for replacing it with a new smartphone (Xiaomi M2S).
I removed battery to force it to switch off, because I couldn't see anything.
I replaced the battery, I connected the phone to charger and after ten seconds (more or less) I removed the battery.
At this point I can see the Motorola logo. I've re-inserted the battery and it shows that it is at 97%.
For sure, the lcd is working
Hi guys,
My battery went completely dead, left it to charge over night, now wont boot at all. If its plugged into the charger and I hold the power button the full battery symbol (black and white) shows for about 2 seconds and then goes off for about the same time then reapers. Any ideas?
Device status:
- Stock rom
- boot loader unlocked
- non-rooted
I've tried :
- Hold power for 30 seconds to a minute
- Hold power + volume buttons for 30 seconds to a minute
- no response form my computer when its plugged in
- no response when trying to boot into fast boot
I am aware this has already been asked. I've tried the other threads but no luck
EDIT
I got mine to boot. I have literally no idea how, I just tried the power button again and it burst into life, although the battery was empty.
I think this could be due to not letting the battery die enough. I normally let my phone (HTC One) so completely flat every month or so but i've never done it for the Nexus 10.
The same problem please help
Serious bump. Ive tried all of these methods, but it just shows the charge icon when plugged in. This is the first time for me that it wouldnt just turn on after going into that sleep state. Charged over night.

I think this is the same issue that many (or a few) people are having. Mine, for example, will be at 100% charge. Then, sometime in the day (without using it) it will die. It will not power on. When I plug it into a charger, it will show the charge indicator on the screen, and I can get it to power on 50% of the time right away by holding down the power button for about 5-10 seconds.
When it boots up, the android tells me it is at 0% battery. If I leave it plugged in it will usually show 100% again after a short period of time, but until then, if i unplug it, the tablet powers right off.

Here is a pretty good thread to see the issue.

Here's a question for you:
Watch your battery life. At any point, does it begin NOT draining? Such as remaining at 60% for 2-3 hours during usage? If so, you may have a defective motherboard and require warranty replacement, as that was one of my symptoms.
