This might help if you hold the power for a long time it should power on, if you have warranty you could send it in? Good luck........

Leave it charging for a good couple hours. It sounds like you really run it dry. And when in bootloader... You can literally run it dry. Always charge around 5% I would say.

A lot of people are having a problem with the battery wire. Kind of a longshot , but if you open it up, the cord to the battery might be loose. I would look it up a bit more but a ton of users are having that issue.

Make sure your laptop is plugged in & charging as well, otherwise I don't think it will work.
Make sure you have the drivers installed as well. I read in the motorola site somewhere that the computer won't charge unless the drivers are installed. Also it charges much slower than the wall outlet does.

Usr USB 3.0 port if your laptop has one so it supplies more power. USB 3.0 will charge almost as fast as AC.

Just let it be. it won't turn on if the battery is below a certain level. Let it sit and charge and it will eventually turn on.
Here we go again.. Only the 1,500th time this has come up..
yes.. Have you been flashing ?
And if it stucked on bootloader you will need factory cable...
Or ..
You can buy a charge only cable just like me, from ebay.. Very cheap.. The phone can boot without even battery! That's why it can be charged if you stucked o bootloader!

This happened to me and you need to plug it in an AC wall charger I left mine on a usb for like 3 hours and it did nothing but on an AC wall charger it took 5-10 mins then it terned on. Hope this helps.

You returned it because of battery life?. What do you mean?.
I tought you returned the phone because of the locked bootloader and because its a bit easy to brick it.

I respect your work but don't give absurd reasons for returning your phone.

Battery drained out - not starting anymore

I was playing a game and my battery drain to the point where the device had to turn off.
I plugged it in after and it just wont start. Also once plugged in the battery charging animation dose not show.
I had similar thing happen to my nexus s when the battery drained out wile using the navigation and the way I resolved was to remove the battery and put it back in. But on the nexus 7 I don't have that option.
Anyone experienced this?
Try leaving it charging for a while, or try holding the power key for several seconds (like 60), sometime that will start a reboot.
Same problem for me
Hi
I have the exact same problem. I was playing Fruit Ninja and boom the nexus turned off with a warning that battery was completely drained. I left it uncharged for the night. When I tried charging the next morning, it wouldn't charge at all.
Not sure what to do. Have tried pressing the power button many times but still does not work.
Does anyone have a solution?
Thanks

[ Q ] not turning on

So my nexus had been unplugged and without charge for about 3 weeks or so, I've been very busy at work. I try and connect the tablet so that i can use again and the screen flickers for an instant and nothing happens, I don't see the white icon charging animation and no response after that. It's my tablet done or is there a solution for this. Thanks to anybody that can help.

Ok, I don't really know what exactly the problem is. But I think the battery seems to be dead. because if it is still good, at least it shows the indicator light when it's plugged with charger.. If u have a simple tool to test battery energy maybe u can find out. or maybe try another battery..
Leave it plugged into the charger for a good while and then hold down the power button hard, for about 30 seconds. See if that forces it on.
How long did you leave it plugged in for? It may take a few hours...

It was plugged for like an hour or so and no dice.

Not sure if it would help your specific problem, but my thread covers every fix known-to-man for issues such as yours. Check it out if you haven't yet.

Try leaving it plugged in overnight. I once had a laptop battery die on me, had to plug it in for like a week before it would turn on again.

Your device is hibernating to prevent further damaging the battery. Plug it in... boot to bootloader... select power off using the volume keys... the tablet will now charge normally

hi
My problem is solved, I have a friend who had the same problems with the tablet Nexus 7 16GB, the back of the unit opens easily with just a fingernail to open a case as remote and actually the battery plug is not fully inserted into the camera, a little bit of nail to reconnect the cable and now my tablet displays well 100% load.

Yup - there is a sticky that covers this method, and all the other methods as well. For anyone else suffering from similar N7 issues, be sure to check it out. Either go to stickies in this Troubleshooting section, or use this link.

How do I finally fix this instant battery drain problem?

i hope some of you have experienced this. i'm on carbon rom right now. sometimes when i'm in the middle of an app, it's just turn off and when i plug it in and turn it on the battery is at 0%. i've done a factory reset.
I have never had that happen before. Does your battery meter move? Like does it say sit at 50% for ages then all of a sudden your phone turns off.

no, but it does happen around 50% from my experience.

Try out another ROM to see whether the battery drain still happens. If no, then it's the ROM's kernel.
Yeah I would try another rom or hell even stock. Maybe your battery is defective if a new rom doesn't help

[Q] RED light of death? or battery

Ok so yesterday I had my nexus 4 in the charger at 46 percent and i was about to send a tweet when the screen froze. thinking it was a simple crash i pressed the home button and no visual response then it powered off. now whenever i try to power it on nothing happens. i tried pressing the power and volume buttons. whenever i try to turn it on and i plug it in the red light flashes. sometimes it flashes continiously sometimes it is a solid color. so what can i do it wont communicate with the computer. im not sure what the issue is. is it a battery issue or is it impossibly bricked. i already charged it overnight to no avail.
oh and im running stock cm11 with the stock cm kernel. i just installed it the night before.
It isn't bricked it's a battery issue.
Leave it in your computer or car charger for a few hours at least.
If still nothing report back.
Good luck!

Charging with the wall charger I guess? There have been reports of various members here on XDA that got their N4 running again after the RLOD issue by charging it with a car charger or with their computer.
Anyway, there are tutorials on YT how to take your N4 apart and fix the RLOD issue. There is also one on the Nexus 4 General section(can't post a link right now). Go to the N4 general section here on XDA, then it must be somewhere on the first page.
Good luck and let me know if you fixed it.
