I don't know how many people are still using these, but I have a solution to this that doesn't involve opening up the tablet or anything else invasive.
The problem is that the screen stays on and drains the battery too quickly before android has a chance to fully boot, so it dies and then starts up again. So you want to let it charge as much as possible with the screen off, before finally letting it boot.
The way I do this is to plug the tablet into my laptop (for whatever reason this technique doesn't work with the wall charger), and then hold the power button down for like 5 minutes. Don't let go of the power button, just hold it down.
After the initial 30 seconds, the tablet will go into a boot loop of having the display on for about 2 seconds, and then off for about 10 seconds. The battery is charging during that 10 seconds, and the 2 seconds of display time isn't enough to fully drain it. Just keep holding that power button. After 5 or so minutes of this, once the display comes on just let the power button go. It should boot up completely into android and dim the screen (but hit the power button to turn off the display once it's fully booted up, just in case).
Android should now be slowly charging, and the lock screen will say it's at 0% or 1% and charging slowly. Just leave it alone and it will fully charge. After a minute it's usually got enough power to quickly switch from the laptop charger to the wall charger, if that's your preferred charging method.

Constant Rebooting?

Ok, so my Kindle Fire is rooted running an older version of CM9 (Late January) and since I don't use it very often it just sits there. Well, it ended up draining the battery and when I plug it into the wall to charge it just tries to turn on, gets to the FIREFIREFIRE bootloader logo and shuts off instantly. Over and over and over...
I've had it plugged in for about 20 minutes now and nothing is changing... How can I make it stop so it will just charge? I feel like its just booted and draining faster than its charging now.
Just let it sit for over an hour, came back and the screen was off with the light just flashing.
What now?! I unplugged it, and plugged it back in and it just resumed the screen flashing again...
I hope it didn't break because of the stupid battery
- plug it to the wall charger
- press and hold the power button for ~20sec till it turns off to allow it to charge
- let it charge for some hours (over night)

No dice, it won't turn off. I held it for over a minute while looking at the power light from an angle. It just kept on blinking green...
Btw, here is another thread for this

[Q] Charging Screen Hangs

Does anyone else have an issue where the Nexus 7 hangs on the charging screen? My son has a bad habit of letting the thing run down until Android shuts down. When I plug the charger in it'll boot to the charging screen and then hang. It doesn't do the typical charging animation I'm accustomed to on other devices and I have do the long press on the power button to get it to reboot.

It used to happen to me too but the thing is that Nexus & uses Li-Ion battery, which means a long life cycle will kill the battery in a shorter lifetime, like laptops. So don't let him play with it until it shuts down. recharge the battery before it hits 50%. Next time when it shuts down, plug it in and let it charge while off for 2 hours then you can turn it back on.

[Q] Random reboot and no longer booting

Hi, so I've been doing a fair bit of reading, but I've not really found anything thats exactly like my issue.
So I got the Nexus 4 yesterday, today I've been using it for probably 3 hours, it was charged overnight last night to 100% and was still at about 65% when the phone randomly rebooted, no force close or anything. So it attempted to boot back up, showed the Google logo and then the nexus X, before going to a black screen.
From here I can't turn it back on, I've tried:
Power - up to 60 seconds
Power + Vol Up - up to 30 seconds
Power + Both Vol - up to 60 seconds
I then plugged it in to the wall (using the charger provided), there is no sign of life still, no battery charging screen, no flashing red led.
If I hold down the power button, while the phone is on charge, I do get the flashing red led.
Is this a case of leaving it to charge and assuming the battery is completely drained, or should I be contacting Google to start an RMA?
Should probably say, as I've only had it a day, no root, no custom rom, everything stock and on 4.2.2
Thanks.

Nexus 10 won't boot after charging

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.

Help Pls. My Nexus 7 2013 wont turn on.

It won't turn on even the battery icon is absent when I try to charge it. Also when I hold the power button for 15 seconds it only blinks/pulse 3 times(notification light). I bought this tablet at Best buy...and it's over 15 days now.
Can I still return. This one or get a replacement from Bestbuy/Google? My tablet isn't rooted yet with locked boot loader too.
Thanks.
Hold the power button for longer, like 30-60 seconds.
If that doesn't work, connect to charger and let it sit for a while, then repeat.

Thanks...it works now...and the battery was so drained it didn't power up for a couple of minutes ... . I checked the battery section and it was mainly caused by Vonage app...I don't know why ...it should consume about 50% of the battery... I just used it once . :/
I'm having the same problem I am completely stock with a locked boot loader. I had just took my device off the charger and it powered on and I saw Google so I thought it was starting up, when I looked back the device was off I've tried holding power for 30 seconds and even tried putting it back on the charger,but its not even showing the charging indicator.
Edit:I got it to work, I left it off the charger for 5 minutes and then tried charging it again and It started charging. I turned it on and it said I had 65% battery so I find it kind of weird that it didn't start up.
