There have been many cases like these. I think you will get enough hits if you use the search button. I had it myself recently, though the solution seems not to be very solid.
The best way to get it to work is to try different cables/chargers (via PC/Wall Chargers etc) and let it charge for a half hour, and try to start it. If it doesn't start, try another combination. Rinse, repeat.
A stronger charger seems to work better most of the time (2A for example).
In the end I got it to work with the 2A charger of a colleague that he always carries with him. I am assuming that there is nothing wrong with your battery besides it being completely drained.

Im not really sure though. Is that what the flashing red light means?

Open the phone up, pop off the battery connection, put it back, then try to reboot (you can reboot with the cover off). I got the red light after my N4 crashed doing an Antutu test after OC'ing it to 1.9GHz (yeah...don't do that), and after "resetting" the battery, it booted up just fine.

I had ever occur this issue and tried any fix from internet, finally completely battery died, so just buy a new one of battery .

Your battery is discharged to a critical level (1-2%) and the phone performed a shutdown to save itself.
Connect your phone to the charger and press POWER + VOLUME DOWN, to enter recovery. Then reboot from recovery
I had the RED LIGHT flashing and this is how i fixed my problem. No need to buy a new battery

Ur phone can't boot up cuz there is not enough energy from ur battery, so just charge ur phone for a while then u can boot up ur phone again red light issue usually for low battery and the phone can't booting up

i doubt it if mine is power issue. I've charged for long periods several times, i've tried several things i could find on the internet, i used a working battery, still no show. light blinks for a while and goes off when plugged to electricity. I'm thinking this could be a different problem entirely

Charging problem ..

(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.

Flashing red led of death

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.

dead

It appears dead. It's late at night so i've yet to try googling about recovery through a pc of some such, truth be told while i can flash a rom with instructions, i'm no guru or anything. It was running CM 10.2? the latest stable release for N10, think that's the one.
I was just browsing a forum, and after posting, the disply started to stutter as i scrolled up, when i stopped scrolling, the stuttering decreased, and then as i scrolled and scrolled fasster, the stuttering increased until display turned black (stoned curiosity...) and now i can't get anything out of my N10. Holding power, trying to reboot into recovery. Nothing. No lights, sounds, vibrations. None of the normal stuff.
anyone got any ideas for me to awke up to? I think that if i can't get any life out of it, then would it be a case of trying to sideload or such with ADB? as i say, i'm a complete rookie, just a couple of flashes under my belt.
Second question, i probably have the answer to, but am i right in thinking custom roms void the warranty?
edit: Plugged it into the wall a few minutes ago. It had had about 40% remaining, but when i plugged it in, i got the battery simbol on the screen (big white battery charging in center) and any time i press or hold the power button, or with volume buttons, i get nothing but the icon. I'll keep it plugged in for now and see what happens. But by the look of i assume if it can do that when plugged into the wall i sohuld hpoefully be able to connect via my computer in some manner
If by stuttering you mean blinking, this has happened to me when my N10 was on charger with a dead battery and it drew more power than what the charger could provide. When you scroll, the CPU frequency gets bumped up and the tablet consumes more power. After a while it just turned off for me (when I changed to an other app I think), when there just wasn't enough power.
So I would suggest leaving it on charge for a few hours, then try holding all buttons and see if you can get into bootloader. I've had the battery levels not display correctly on some custom ROMs, (for example I would do a reboot at 60% battery and after it reboots it only said 13%) so just charging it a bit might solve the problem.

Thanks. As of 5 minutes ago it got back to life. All battery apps showed 40 odd. Strange.
i think your battery has gone/ on its way out, exact same happened to mine, you need a pogo charger and the original wall adapter to provide enough power to switch it on. Only thing which worked for me, hope it works for you.

Might be the battery, might be glitchy software. Plugged it in via USB and it worked sometime later. Will be keeping an eye on it.
It will probably be fine. I thought I had a bricked N10 but turns out the battery was dead. It is fine now. THought I had a bricked N7 also, turned out the battery plug got loose, (screen would flash every 2 seconds with static on the screen) popped it open and oushed the plug in and that is fine now too.
If it continues to die around the 40-50% mark, you'll need to send it in for repairs. Make sure they don't just try replacing the USB port on it, the battery itself is the culprit.

[Q] N4 only turns on when charging

Couldn't find any response or anyone with the same problem here. If it's the right place. Please, let me now.
I only can use it when it's plugged at the wall charger. And sometimes I can enter fastboot and recovery using the laptop. When I take out the cable, it dies again.
Tryed all stock versions (4.2, 4.3, 4.4 and 4.4.2) and all the same.
Tryed three new batteries and then go from 0 to 100% in one minute the go back to 0 and starts charging again.
I noticed that every time I try a new battery, it show the red led, and to start charging, I must hold power 10-15 sec then i can see the battery icon with the flashlight then charging. But when I press power after 15 hours of charging, the red light appears again. So i keep pressing and it turns on, but with the same result.
Any idea?
PD. Sorry about my english.

I am curious, how are you able to so easily swap out the batteries?
Has it always behaved like this (from new), randomly one day or after you changed something for example ROM, Kernel, some hardware etc?

After the first one, you are able to open and close it in 2 min.
One day it turned off and never woke up again. :crying:
Nobody? I'm about to put it in the garbage.
I've got a similar issue to the OP, I can force my phone to start, and have left it to "charge", but as soon as i disconnect the charger, the battery percentage goes down about 20%. if i then turn the phone off, I get a solid red notification light for about a second. to get the phone to turn on, i hold down the power and volume down buttons. If i hold down the power and volume up buttons, it appears to start charging, but never actually does. Any suggestions on how to get it to charge?

[Q] N4 doesnt turn on. Red Light blinks once.

Hello.
When I try to turn on my N4, I hold power button, and after about 10 seconds Red light blinks (just once, if it's connected to USB that 1 blink last for 3 seconds, if connected to wall, it's just quick 1 blink. If it not connected anywhere there is no action at all, it just stays dead, no blinks, nothing). Same if I try to go in bootloader by holding volume down+power.
This happened after I successfully installed CM12, with no errors. Then I rebooted my phone, and it just stayed black as it is now. Battery was around 25~30% that time, and phone was connected to USB.
Did I bricked my phone totally? I am now trying to charge it up already for 1 hour... but it nothing changes.
I have searched here for similar problems, but couldn't find solution...
Edit: Charging already for 10h+ , still same..
Edit2: I removed battery, reconnected after a while, still same problem.
So I tested it with multimeter, it says 2.6V, but fully charged must be 3.8V. Could this be a problem? I was charging it for whole night.
Edit3: I just got new battery . But it looks the same.. phone doesn't boot up.. same red light blinks once.. so.. its my phone is dead? I can't believe that...
When I connect to PC usb, there are unrecognized deviced called "QHSUSB_DLOAD".
easy fix
Hold down the power button and the volume down button at the same time until phone reboots. If you see the little android no need to worry just let go and wait for your device to reboot on its own. This is not a factory reset it's just like restarting your device. :good:

I have tried that many times. Nothing. It's bootloader screen, but I can't get there. Nothing happens. If I keep holding volume down+power it just keep blinking once every ~10 seconds, same if I hold just power button. If phone is not connected to charger, there are no blinks at all.
I removed battery, reconnected after a while, still same problem.

I had the same problem a year ago, I tried to remove the battery, charging all night, and other solutions that I found online and no one worked.
Finally I found here in XDA a user with the same problem and his solution was charger the phone with a wireless charger, a friend of mine has one and I put the phone to charge and after a few minutes the screen goes on and the phone was charged, then I press power button and the nexus run again.
Hope this works.
Sorry for my bad English, I'm from Spain.
Good luck.
(I bought a wireless charger in case it happen again)
I don't know anyone with wireless charger. I already ordered a new battery, and then I probably will get wireless charger also. Ty.
But this problem is very weird if you think so.. I think it happened because of many aspects together:
1) Battery was already below 30%
2) I pretty regularly charge phone with USB (won't do it again)
3) It was connected to PC USB in same time.
4) I installed CM12 ROM in same time
So main reason I think is USB, that I restarted phone while it was on pretty low battery and with USB connected.. phone restarted and got invalid voltages and couldn't even boot up or charge phone. I also found an article which says, minimum voltage, when phone battery has 0%, it's 3.0V, so I was below that.. it just screwed everything and battery died. Well, I am not sure for 100% that it's battery fault, but I hope so, I really love my N4 and still wanna use it for long time, I hope it's not dead phone, just a dead battery. Lets see! I will update this thread , when I get my new battery (less than month probably).
Sorry, my english is also not perfect. I am from Latvia.
I was playing when it happened to me. The phone was very very hot and the battery was around 70%. When I put in the wireless charged and I can reboot the phone the battery was at 65%, so it had charge but the phone won't boot.
I charge my phone almost every day, sometimes with AC, others with USB (plugging to PC) or wireless that depends of my needs
I hope you can fix it. Good luck.
Btw. Do you know if battery charges with wireless charger, if it's removed from the phone?
Don't think it does, since the receiving coils for wireless charging are located just behind the glass back.

The battery will charge with a NCF Charger
Major Issue Google
This "Nexus SOD" issue is showing up on many sites across the Internet. I have multiple "Nexus" devices including 2 Nexus 4, 1 Nexus 5, 2 "Nexus 7 2013". It suddenly started out of the blue with one of my Nexus 4 phones. Symptoms included rapid battery discharge. I am using Lollipop 5.1 on all devices. There are many claims as to the cause, Hardware Motherboard, Power Button etc. Others claim it is "Software Related" or App Related. The problem effects Nexus 4 and Nexus 5 phones. I have ordered a new motherboard for my nexus 4 device and see if that makes a difference.
This problem should warrant a "Major Android Lollipop Crisis Team" by Google to investigate the cause and let us know what it is and what Google is doing to solve the problem before moving to announce "Android M". This issue needs to brought up and actively pursued at the upcoming "Google I/O Conference" by the strong Android Developers Groups to press for "Formal Action"

I have tried that many times. Nothing. It's bootloader screen, but I can't get there. Nothing happens. If I keep holding volume down+power it just keep blinking once every ~10 seconds, same if I hold just power button. If phone is not connected to charger, there are no blinks at all.

I had this problem a long time ago and my fix worked for me after doing a little research it seems like this is a case called battery total discharge. The fix was simply to charge your phone using the wall adapter that came with your phone (I still use my old apple cube wall thing) and to wait for the red light to appear then wait about ten minutes before trying to reboot.
I just got new battery . But it looks the same.. phone doesn't boot up.. same red light blinks once.. so.. its my phone is dead? I can't believe that...
When I connect to PC usb, there are unrecognized deviced called "QHSUSB_DLOAD".
Maybe this video will help you: Oh I´m not allowed to post links until now.
Just search for: - Nexus 4 "red light of death" fix - at youtube.
Hope it will help

I have checked all kind of videos there. Also that one. Most of these cases are related to battery, but it seems in my case it isn't. I just searched for QHSUSB_DLOAD unrecognized device, all posts says it means phone is bricked... But cmon, how? I installed CM12, successfully, without any errors, then just restarted phone, and its dead...

Did u try booting the phone without battery by connecting to wall charger and what about flashing stock ROM via PC
Also check that the power button works
This case should be solved

Just tried booting without battery, and connecting to wall. Same - red light blinks once, after I hold Power button or Power+Volume down for about 15 seconds. If I keep buttons pressed, it just repeats every ~15 seconds.
Power buttons works fine.
After I checked that Device manager thing in google.. it looks very bad.. phone is dead.. probably need to change motherboard. I am just shocked, how this could happen... I didn't receive any errors during CM12 installation. Phone just instantly died after restart.
