[Q] Battery won't charge - Nexus 7 Q&A, Help & Troubleshooting

My N7 died for the first time last night so i plugged it in. The next day it won't turn on. So I plugged it back it and got it to power on, but it only gets to the homescreen before shutting down and the screen flickers. That's with the cable plugged in. If I do it on battery it gets to the homescreen then gives me a low battery warning and shuts down. The recovery menu loads and freezes instantly with our without the cable.
Any ideas on a fix? The only thing I did to it was root it a few weeks ago.
TIA,
Mike

Plugged it in last night again, it apparently took a charge and seems ok now.

[Q] [NAND] Turns on and dies.

On my TMOUS HD2 I am running a build of Desire 2.2
Its been working great for the better part of a week.
The only kind of problem I have been having with it is when it dies, I would sometimes need to pull out the battery before it would once more charge.
But that really wasnt a big deal for me, my thinking was, well i'll just start charging it before it dies.
Last night I was up playing angry birds and the battery became pretty low, so I called it a night and I pluged it in to my Chome Notebook for an over night charge.
When I woke up this morning my phone will no longer turn on.
My first thought was my notebook lost power and in turn the phone never charged, but that wasnt it.
The I thought maybe the notebook didnt send out enough power to charge the phone ( I have charged it through this notebook before ) so I plugged it into the wall and the charge light just blinked... almost as if it had a full charge.
I went to boot it up and it only flashed my boot screen before shutting off again.
After I repeated this I would eventually get to the MAGLDR, but right after it would shut off.
I took the battery out for about a minute this next time and I was able to boot all the way to the DFT screen, but it shut off yet again.
I checked to see if I could get into the bootloader screen, and I could, but it still shuts off when I get in there.
So currently.... I have it with the battery out for another half hour before I try booting again.
Ok, its been 1 hour now I put the battery back in. When I pushed the power button it didnt do anything. But when I pluged it in, it turned on to the boot screen and once more turned off.
But a few seconds after that the charging light came on.
I am going to leave it like that for a bit and see where it gets me.
Right now, I have it charging from the wall. I will leave it there for an hour or 2.
haha, any ideas?
atm you can't charge the phone with magldr installed when the phone is off.
hope it helps
I don't believe that is the actually problem.
I had left the phone on the charger for the past hour and a half and just started it up, and to my surprise it loaded all the way back into android and showed that it was actually charging.
I guess.... maybe it was slowly dieing over night because it was not getting enough charge from the notebook.
And when I woke up and check my phone it was so drained it couldn't even boot past the boot screen.

[Q] Phone suddenly went dead (latest MIUI 2.6.35 kernel)

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).

[Q] When turning off, a fully charged battery has 0%

Finally receieved my Nexus 4 after almost 2 months waiting, but not really enjoying it right now.
Received it yesterday, unpacked it and I couldn't turn on the phone. So I've connected the cable into the charger and a light showed up.. After 30 min I saw a battery icon and after 1 hour I could turn up the phone.
When turned on, it showed 3% battery, so I let it charge for about 5 hours. While charging I've noticed something strange.. it was charging very slow. After 4h of charging it was showing just 16% battery and 1h later it was suddenly at 70%. After it got till 99% I unplugged the charger and tried to use the phone.
Everything worked till I wanted to restart it. The phone doesn't want to start up! Pressing the powerbutton for 20-30 seconds.. nothing happens. Tried the volume button combination.. nothing. Plugged it into my PC and after 10 min the battery icon showed up?! The battery was at 0%! The battery went from 99% to 0% just by turning it off!
I've let the phone charge again, this time the whole night (7 hours).. It was fully charged at 100%. I disconnected the charger and turned off the phone.. and again: a black screen.
I've Googled and searched everywhere but couldn't find 1 thing.. what could be the problem of this? How can my phone go from 100% to 0% by turning it off?
I have no idea what is going on but you need to contact google asap, they'll send a replacement and hopefully the new one isn't a dud.
If you want to try playing with it, plug the phone into a different charger with a different cable, let it charge overnight/12hrs and give it another shot it could be a bad cable/charger (to be honest I think this is a long shot.)
Really sounds like a hardware problem.
Your only option is RMA.

[SOLVED] Phone problems.

This morning I picked up my phone and the screen wasn't powering on. I figured the battery died since it had been off charge a few days, however when I plugged it in all I saw the was green notification LED show up. After trying power + vol down the green light disappeared and quickly reappeared. Not sure what to do from here. Plugged it into my pc as well, PC didn't see it so I can't use ADB. I am using CM10.
edit: yep, battery died.
Erm.. maybe the battery was dead. After a bit being plugged in the CM10 loading screen showed up. My bad, went panic mode.

Complete shutdown while charging

Last night I had my AT&T GS4 charging. I woke up in the middle of the night, and since I am addicted to my phone, decided to check to see if I had any messages. However, my phone had shut completely off in the middle of the night while charging. When I pressed the power I didn't get the green battery either. I unplugged it and held the power down for about 10 seconds and it came back on. Has anyone else had a problem like this? It makes me nervous now since I use my phone as my alarm clock.
