Edit: thanks to this post, my problem has been solved. Thanks!
So last night I went from stock motorola 2.2 to this wonderful-seeming version of CyanogenMod on my UK milestone - the install went flawlessly, but now I have a problem - my battery is not charging at ALL.
While the phone was on last night after I charged it, it was plugged in, first to my PC and then to the wall socket. In both cases, the battery indicator had a ? (question mark) on it.
I thought it might have been some weirdness with battery calibration so I left it and plugged the phone in from the wall to charge overnight. This morning, my phone was telling me to connect my charger (despite it being plugged in) and on removing the power cable, it died due to no battery power left within 10 minutes.
While plugged in from the wall, the battery indicator comes up but again just contains a ? on it. The little white light next to the power socket never lights up.
If I plug the phone in to my PC via USB then if the handset is OFF, the white light comes on and around 10 mins later it gets enough juice to boot up. The problem is that when the CM7 software starts, the little white light disappears, the phone stops charging despite the cable being present, and it then dies 2 minutes later.
I know the battery is fine because it was perfectly fine before I installed CM7.
Anyone else experienced this problem and/or know how to fix it?
One thing I did manage to do before it died was install a battery calibration app that I found on xda-developers - this told me that the battery was running at 3267 mV - any idea if that's good or bad?
(and yes, I'm using precisely the same cable/charger I was using before I put this version of CM7 on, so I know they are fine - they charge a friend's SGS with no problems)

Try plugging the phone into the wall charger, without the battery. Try and boot it up and let it boot. Once it's booted up, give it a bit and try and put the battery in and leave it to charge.
What happens if you turn off you phone and plug it in a wall charger? If the problem isn't in your battery it will charge fully.
When you phone comes up, try to disable the 1% battery steps in settings. I got a problem with it, and after disabled/enabled it worked fine for me.
Hope this helps.
On plugging it into a wall charger, the phone comes up with its special battery charging screen (i.e. a fullscreen battery level indicator) - no amount of pressing the power button seems to get it to boot properly (with or without the battery).
I'll see if I can get in and get rid of the 1% steps thing later, thanks for the suggestion

Dude, that was PERFECT.
Managed to get enough juice into the thing to get into the menu for a moment and was able to disable the 1% battery steps option - soon as I touch that tickbox, the battery indicator switches from a ? to the charging symbol and the phone starts charging. Thanks a million!
Nop dude, you are welcome
I leave my touch pad on the touchstone overnight and randomly the screen comes on and then times out and turns off, I use dock no op app to have no event when docking, any one else had this issue?? I'm using cm9 alpha 2.
IIRC it will wake when it hits 100%, then stop charging and discharge slightly, then charge back to 100% and wake. Rinse, repeat. That is how android phones generally charge. I have a case on mine so if it wakes during the night I don't know. I know CM7 did what you describe, because I didn't have my case then. My solution at the time was to not put it on the TouchStone unless it was lower than 70%. I also use the app dock nothingness to prevent the clock showing up when I put it in the charger.

I think its a problem how u put u'r touchpad on touchstone. If it is not stable it can happen. If the charging stops screen will on. It can happen if use a protecting cover. I don't have any problem with touchstone.
Thanks, I tried taking my HP folio case off and turning off wifi... so far it hasn't come on, although it is at 100% charge, I think it was turning on when emails were received.
I was wondering if anyone else was having this issue.
I've charged my Nexus7 overnight on three occasions. Plugging it in before I went to bed (~1AMish) and getting it on my way to work (~8:30AMish). Out of those three times, on two of them, when I went to get my tablet the unit was powered off. I know for a fact that when I plugged it in, it was on, and no one touched it in the meantime.
The most recent occasion was this morning.
On all three occasions, the unit still had 40-50% battery life left.
On two other occasions, I've charged it during the day for a few hours, and it was fine.
Additionally, I've never had the unit turn itself off overnight when it wasn't plugged in. And I'm using the charger/cable that came with it.
Lastly, the first occasion was on the stock kernel/rom, and the second was on the motley kernel (but stock ROM).
So it seems like something is causing the unit to power itself off if it's on the charger for too long. This is concerning, because the only thing I can think of is that it's overheating and shutting down as a protection mechanism.
Any thoughts or ideas?
Plugged mine in for the first time last night at 11:30. Slept till 8, hit the power button and everything was fine.
Basically, no issues here.
Was it fully charged when you switched it back on? I ask because I shut mine down for the overnight charge last night (plugged into a laptop, not the wall - there's only one socket near the bed and my battery-sucking phone gets that juice), and when I woke up it had only gone from ~30% battery to 55%.

I had this happen to me on the first unit I had... I was actually using stickmount to transfer some data and left the usb adapter plugged in for about an hour and when I picked it back up it was DEAD.... I could not get it to boot up at all until I did the recovery (power/volume) method and then everything was fine but I returned it anyways cause of a defective screen... I am now on my 3rd unit from Sam's Club and I think I might have a keeper...? (Knock on wood) :fingers-crossed:

Yes, it was at 100%.
Keep in mind that charging via computer's USB port takes much longer. Maybe your laptop went into sleep mode and shut down power to the USB port?

Nope, my fiance's phone was plugged into the same laptop and it was fully charged in the morning. And as a general rule, I've never known the computer to automatically sleep while on AC power, even when the screen is closed.
Thank god i'm not the only one experiencing this. My nexus 7 always seems to turn off after I leave it overnight plugged in for charging. I thought it was a kernel issue but i've switched kernels and i still experience it. Still unsure as to what is causing it.
Same here. Its odd it only seems to be for an extended period of time. Also my battery was indeed fully charged. Should I exchange at Sam's?

There is nothing else wrong with the tablet. I have a feeling it could be some sort of hardcoded feature where if it notices that you're plugged into the wall charger with 100% battery and the tablet is in deep sleep for a certain period of time, it automatically shuts down.

Ikr. First time it happened to me I was like wtf? It might to stop the 2 amp charger from overcharging? My unit is fine, I think the sound is just right. I might get that squaretrade warranty though.

Well, I feel a little better that I'm not the only one with this "problem".
The question is, is this a "problem" or a "feature". I guess we won't know unless we ask Google/Asus (good luck getting that answer) or enough people respond saying that it happens to them too. But if people start saying it does not happen to them, it makes it more likely to be a problem....
This happens to my phone due to overheating. The tablet does run hot when charging. See if there's a temperature logging app and run it overnight.

It would be nice if it would just cut off the battery charge and run directly on A/C. But I guess I would rather have it power off than explode.
isnt bad to charge it overnight like i believe from 1% to 100% chrge is like almost 3hrs fully chrged.. i just alarm myself for 3hrs to check if its fully chrged already then unplug it

True, it's not good to constantly charge the battery once it's full.
Most devices however have a built in charger kill switch once it reaches that point. Laptops for example will switch to A/C power and only start recharging the battery once the level drops to ~95%. I believe my phone does this as well (SGS2).
I guess I'm OK with it turning itself off, assuming that it really is a safety feature. My main concern was something was wrong. It would have been nice if they mentioned this in the 100pg Nexus Guide eBook though .

I want to add my own observation -- mine was almost fully charged, I plugged it to my computer's USB, turned the screen off, walked away. A couple hours later, the Nexus 7 was turned off. But I was shocked to find that, pressing the power button couldn't turn it on. The first thought came into my mind was that my computer did not charge the Nexus 7 and the battery ended up completely drained. So, I plugged it to the wall charger, left it on for a day. 1 day later, I tried to turn it on again. No, it didn't work. I was panic and decided to Google about how to reset and checked if I could wipe it and sent it back for a replacement. I found that pressing the power, vol up/down button at the same time can force a reboot. I tried that and bingo, it booted into the bootloader. Before I wiped, I decided to try to boot back to the Android OS. Surprisingly, that worked. I was happy and decided to ignore this incident. Then, today, it happened again. This time, I immediately used the power + vol up/down trick to reboot, and that booted me right back into Jelly Bean. I checked the battery status and it's fully charged, which meant my computer was charging it all along. For some reasons, the Nexus 7 would just turn off itself. And, in my case, pressing the power button alone would not reboot it.

Sounds like to me that it's hard locking, not "powering off", and you're forcing a reboot. Long-press of the Power button should do the same thing.
I can't say I have much to offer in regards to this issue, but am I correct with my observation that everybody experiencing this issue has experienced it while their N7 was plugged into a computer of some sort for an extended period of time? Has anybody had this happen when plugged straight into the wall outlet?
Here's another update with an interesting 'twist' since my last post.
I've charged it twice in the meantime. Once was, again, overnight, and I woke up to find it powered off. A simple "on" press brought it back on.
However, on Saturday, I used it heavily and was down to about 40%, so I plugged it in around 11AM. I meant to grab it around 3PM when I went out, but forgot about it. Got home late, and went to look at it at about 11PM (12 hours later). It was charged to 100%, running off the A/C power, and still on.
This is weird, because if I leave it plugged in "overnight" for 8 hours, it will almost always turn off sometime before I grab it. But when left plugged in during the day for 12 hours, it stayed on. I wonder if it handled the situation different based on the time of the day???
I charged my battery. Took it off the charger and turned off the screen. When I woke up the phone was off and I dead. I am on cm12.1 fairly recent update. I updated a couple days ago. I just want to know if anyone else had this issue?
Only time thats ever happened to me is when I was camping in the woods. Like it was searching for a signal all night and killed the battery.
I had something similar happen to me over the weekend. I mostly use a Choetech Qi charger, and pulled it off the charger Saturday morning before heading out for a day of motorcycle riding. After the ride...~6hrs later my phone still showed 100% battery. As I was catching up on emails etc..the phone just shut itself down. I rebooted...then it shut down again within 30 secs of use.
While it was still off, a quick press on the power button popped up a battery image showing 0% battery. Within 2 seconds of plugging in a charger...it jumped to 100% again. But the phone would not stay on, unplugged at all. I tried wiping the cache hoping that would clear out the battery monitor, but not luck there. The only that worked was turning the phone off, plugging in the OEM Turbo Charger, and letting it charge over night.
Do you have any app monitoring battery usage like betterbatterystats or gsm battery monitor?
sometime obviously kept your usage on while you slept. not normal. either searching for a signal all night, or a misbehaving app, etc. y
I do not have currently have any 3rd party monitoring app. But it's probably not a bad idea. I just think that something with the wireless charging eventually whacks out the battery calibration. As long as I can "reset" everything with a night on the Turbo charger, I can deal.

Radon,
I'm seeing nearly the same problem, but mine is at 80% not 100%. I tried doing a full charge on a standard (non-Turbo) charger overnight, and it changed things, but still not in an acceptable state. Did you try using a standard charger? Or did you only try the Turbo charger?
Verizon and Motorola are telling me I need to do a factory reset and/or get a new phone, but I'm trying to do my research first.
Clear the app cache (Go to Settings->Storage then click on Cached data and hit OK). Then reboot into recovery to wipe the cache there (note it'll take upwards to half and hour so don't freak out if it looks frozen). Then turn the phone off and leave it on the factory charger overnight (or for a while after it reads 100%) with the phone still off. This clears the cruft to fix misbehaving apps, then calibrates the phones understanding of what a full charge is. You also might want to delete any apps you no longer use, especially ad-ridden games, system hook apps like keyboards, and things that track location or status which might keep the phone awake.
After I shattered my screen on my last turbo and got a replacement I've been having issues with my battery. It would randomly die and wouldn't respond or let me turn it on without connecting to a charging cable. Sometimes it goes from a good charge to 39% and turns itself off but often, like I observed today, when I looked at my battery trend it actually went from 75% to 8% in an instant. Not sure what the cause is. Could the battery be discharging somehow??
