So my phone ran out of juice 4 days ago, it was left uncharged till 2 days ago when i decided to charge it. I plugged it into the nexus 7 2012 charger (which i use to charge many other devices and none had problems including my nexus 5) and the LG logo showed up. After 3 hours i went to check on it and it was just dead and warm. It's completely unresponsive, won't boot into recovery or download, won't show LG logo no matter what button combinations i press. It's not recognized by my PC.
I opened the back case, pulled the battery cable and reinserted it and tried but still dead. When i connect the phone to any charger it warms up but is still completely dead. I tried booting it with the battery unplugged and still dead. What might have gone wrong?
Check voltage of battery (Should not be below 3.7v).
I had issue with mine when battery corrupted. Led was blinking red on charge/pc/power on
I don't think it's the battery, I've already tried booting without it and it won't boot or get recognized by the PC.
You saying about booting without battery, was it "test point" procedure?
I'm not really sure what you mean. I unplugged the battery connector and plugged it in the charger and attempted to boot it up. I was trying to test if the battery was the source of failure but I think it's not since it should have booted up if it was just the battery that failed.
Same with me. I bought a new battery and the same thing happens. Blinking red light. It shows some life for about 3 seconds with the logo coming up but then dies. anyone know whats going on?

Several times when my HD2 had very low power it would go through a reset-reboot cycle which eventually resulted in a power off-> charge (I couldnt get it to merely remain powered off whilst charging as it would always start up and attempt a boot whenever I either put the bat in or pluged it in)
Last time this happened, however, it stopped charging altogther. I have two batteries, neither of which charge. Ive tried several roms and have now even returned to winmo 6.5!
BTW the roms flash ok, but in all cases, the phone restarts at some stage during boot.
The phone behaves as if Ive pulled the battery when I pull the usb cable, hence why it feels to me as if its an issue related to the battery not charging.
Any ideas? Anyone successfully charged up a battery without it being in the phone?
Thanks!
sorry *facepalm* just noticed one of the power pins was bent! Fixed!!
My phone just went dead yesterday, while playing tiny tower. Suddenly turned off, and would not turn back on. When I connect the charger, the led in in the speaker blinks. When the charger is not connected, the phone is completely dead. And it does not respond to anything either way. I don't know if this is rom related. Probably not? I'm thinking returning it to the shop, and hoping for the best is my only option, unless someone here has a better idea.
Update: I tried turning it on, connected to the charger, but without the battery in. It starts. So I guess the battery died? Suddenly and completely?
What happens if you turn it on without battery in and then insert battery?
Mine did a similar odd thing when I first wiped battery stats. Was playing angry birds to drain battery right down and it turned off, but would not start. LED just blinked when power was in. I just had to plug it in and unplug it a bunch of times and it finally started charging.
I did wipe battery stats last week, but have been through a few drain/recharge cycles since then. When I start with the charger connected and insert battery it gets past the boot animation and then shuts off. I tried with a different battery yesterday, and it worked fine. When you say plug it in and unplug, do you mean connecting and disconnecting charger, just repeatedly?
yeah, was just plugging and unplugging a lot and it finally worked. If another battery worked then that would seem to be the fix.
Will try that. Thanks!
Managed to get it to start by putting the battery in after starting with just the charger first. Had to try a bunch of times before it worked. Been charging now for 5 hours, but it never gets past 10% charge on the battery? Do I just let it keep charging or is there some other way to fix it?
That happened to me in the day I bought my phone. It only started with the charger plugged in (and with no battery).
I thought the problem was in the battery, but in the store they tried with a new battery and the phone did not connect. So they replaced and everything is fine (since September).
Noticed my E900 was unexpectedly powered off. Tried to switch on and got the LG logo for 3-4 seconds, then... nothing. Seems to power off. Failed to boot?
Subsequently, power button did nothnig. After removing/replacing battery and powering on, I get the same LG logo for a few seconds, then nothing.
The LG logo tells me it isn't a dead screen. Connected to PC/Zune and nothing seen.
Are there any button combinations to do a reset?
I have ordered a new battery, but I think that's unlikely to help.
Any thoughts?
Thanks.

I had already tried charging the phone of course, and had left it plugged in for several hours. No change, still as dead as ever.
But later I connected to a PC. No sign of life from there, but I happened to leave it connected. An hour or so later I noticed it was displaying the almost-full-screen picture of a battery, with a small fraction of green at the bottom.
So it seems the battery had been totally drained to the point it was (almost) unrecoverable. Perhaps it was the low-current trickle from USB that got it going again.
Back up and running now. Glad I didn't panic and buy a new phone!
About a month ago, my nexus 4 battery was acting weird. The device would just turn off and when i looked at the battery app, it would just show the battery being drained then showing it at the regular percent when it booted back up. Eventually it just died and wouldnt turn back on and when i plugged it in it showed the solid red light. Nothing I did made it change from a solid red light so i ordered a new battery for it. So now I order a battery and switch them out. It shows the charging animation and when I go to turn it on it says google for a second then the red light flashes once then shows the charging animation. No matter how long i have it plugged in, it will not turn on. I can hold the volume down button while turning it on and it goes to that menu and doesnt die/restart, but if i choose any of the options then it will do it for a second then die, showing the charging animation. I had stock everything and never rooted it. Any help would be super awesome and thank you for your time in trying to help me out.
Send it back to LG for warranty. You don't mention if the old battery was tested or not. My girlfriend's old Galaxy S1 stopped charging. We ordered a 2nd battery and external charger for it for under $20. My guess was that something in the circuitry of the USB port was shot since it also would no longer sync through USB. But she was out of warranty.
Since the N4 hasn't been out for a year yet then it is still under warranty - I'd say this is the time to use it.
I recently acquired a Defy and immediately installed CM11 on it. My main phone is a Nexus 4 and one of its best features is that even if the battery is completely drained, if plugged into the wall charger it will immediately boot up. The iPhone I had before would show a low battery screen until it reached around 10%, at which point it would finally boot.
It seems that when the Defy battery drops below 15-20%, it will not boot at all - pressing the power button does nothing. I plug it into the mains and the usual white light does not show. It still seems to charge and I can eventually boot into recovery to see that power has reached around 20%. At this point if I disconnect from the charger the phone usually boots up. I haven't had it long enough to troubleshoot extensively but I think that while plugged into the wall it is less likely to boot successfully. An unsuccessful boot starts with the Motorola logo, then the screen goes black and the buttons flash once, at which point the boot fails.
Is this at all similar to the experiences of anyone else, or could it be a battery / firmware problem?
Thanks
Have you tried to remove battery, insert it again and then try to boot?
I had the same problem once, I'm on cm10.2. Maybe we should replace the battery, I always charge it before reaches 30%
