I'm having an issue with my Nexus 7 8GB that my wife primarily uses. We have a IP camera that we use as our baby monitor for our son and we use the app TinyCam Monitor PRO to monitor that all night with the Nexus set up on the nightstand plugged into the factory ASUS charger. Running this app, which keeps the screen on all the time and the WiFi flowing constantly, the Nexus will get shut off in the middle of the night when the battery eventually drains down to 0 - even while its plugged in and charging!
I've installed the latest version of Paranoid Android ROM so that we can fullscreen kid apps for my son to use and not easily escape to the rest of the OS. The "stock" PA kernel that comes with that ROM has this battery drain issue as well as Faux123's latest kernel. Both behave the same way. It did not have this issue running a stock 4.2.2 rooted ROM with a stock Google kernel.
Does anybody have any suggestions on what else to do about this? Obviously, using it as a baby monitor is more critical than being able to full screen select apps but I'd really like to be able to do both and don't see any reason why I logically should not be able to.
Are there any other ROMs I could try that allow the fullscreening of selective apps like Paranoid Android?
Come on people, has anyone ever had this problem before?

oddly enough, i think that has happened to me before (also using oem charger)
it happened when i was running an game that was "eating up" battery faster than what the charger can charge ....... if that made sense
Mine is doing this even with no apps running in the background. I thought it might have been my charger so went an bought a new oem nexus charger but it still drains unless I turn the tablet off to charge. As of now I have the second gen N7 but I still would like to make my original work right.
I've updated to Paranoid Android that's based off Android 4.3 and have tried out Franco's kernel with it. This battery drain is still happening but it's at least tolerable now. My wife will go to bed with the tablet plugged in and charging at 100% and wake up with it around 40%, still plugged in and charging. So at least it does not turn itself off over night. In my case at least it does seem to be software related.

Got a wierd problem. i am currently running cyangen 4.2.6 on a g1. Ever since i converted to 4.2.3.1 and updated to 426, my g1 will randomly crash and not come back up until i plug it into a charger. It will many crash when i launch any app. I constantly check battery levels and it will do this on a full charge or any level of charge. Is it the battery or the software?
I flashed original rom but my battery behavior is still like on 2.3.5 RC4. Charge to 99% and drains very fast. Did someone know how to get back it original life. I tried battery calibrators from the market and battery wipe from clockwork mod but no result
If your optimus is old it is normal that battery life will get worser and worser ... All you can do is get new battery of ebay like I did and now my battery life is normal ...
Mike
It's not old. Its younger than a year. Battery life was good and on swift it last long and charge to 100% but after last time i flashed 2.3.5 rc4 i calibrate it (to try it last longer like on other roms) and now even on stock it drains like on rc4 and not charged to 100%
Use spare parts to see is there app that drain battery.
install "batterycalibration" from market, charge to 100% and calibrate your battery for this rom
Yes i download two battery calibration programs but the problem is that it's not charging to 100% but to 99% and drains very fast after this. i'll calibrate it a few days hope to fix
yeah, that happens to most people.
unplug, use a few seconds or 1min or so and plugin and wait if its fully charged, it could be that you have to do that a few times (2-3x)

Your not alone on this, same thing with me.
I have ordered another battery from ebay but dont really know why all of a sudden this just began happening whilst using the same Rom which I think has something to do with it.
I use a program from Market called Android Booster to terminate running programs that start up or dont close once started, as sometimes if you use your camera, it will be still running, even if you close it up so hence battery life turns crap.
But also, if somebody phones me for 5 minutes this also nearly drains my battery, and I have everything also turned off. (WLAN, Blutooth, Data, GPS etc).
So dont know why this is suddenly heavy on the battery as it never seemed to do this when first installed.
There you have it, your not alone but think I will migrate to another or buy another phone as I think its pathetic to have to charge one's phone everyday, or twice a day if you chat to somebody for 5 minutes as it defeats the purpose.

Try charging through the wall charger instead of through the USB port on your pc. Worked for me then, recalibrate.

I got my brand new battery and even charged it up via Power Supply from the wall.
Have run the phone only on 2G network only box ticked and everything else turned off (and I mean nearly everything) and for whatever reason, the Battery new or old still does not last long.
Even after it charges to 99% says its charged, it discharges very fast, or if somebody phones you and you only talk for 2 minutes the battery drops to like near 30% which is pathetic.
Something is sucking the life out of the battery folks with these Rom's so can somebody exactly put the food on the table here and say, whats up?

What ROM are you using? It takes some time to charge up the battery and even if it says '99%' that doesn't always mean that it is. What is the capacity of the battery? I'd say charge it for about 6 hours and see then.
Thanks Johnny,
Problem at present seems to be solved now.
Yesterday and before I had been using Mur4ik's CM7 2.0 RC4.
I then uninstalled a stack of apps that I only used every so often and now its like back to normal so I guess it must have been those apps installed.
Folks here is a big tip. Uninstall Apps to test your battery to find out which one is the Energy Hog because even if you are not using them, they seem to be running due to either bad programming of the app or a system management issue related connection between the two.
Now, I have just updated to Mur4ik's CM7 2.0 RC5 and will certainly think twice prior to installing a bunch of things for the sake of installing apps.
Cheers people~!
I've been running cm-10.0.0-epicmtd.zip "Stable" since it was released. I wiped the phone and started from scratch before flashing it. I had been running various RandomRoms prior to CM10
I found CM 10 Stable to be buggy for me. It would often shut down applications I was running, most notably Waze navi and Torque OBD2 logging software. It would also sometimes leave me with a black screen on bootup, which required a battery pull. I also had an issue where GPS would never work after a reboot, unless I first turned GPS off then back on. To top it off, I found battery life to be pretty poor. Even if I turned off data when not using it, it would still suck a battery down in 12 hours of light use. I have 2 spare 1800 mAh batteries, so that was not a big deal for me. The final bug was that it some times would take a reboot to get it to download MMS pictures.
I flashed CM10.1 M2, from the CM auto-updater, a few days ago and have been very happy with it. I had to flash the latest GAPPS as well, and delete the clock data. The only other bug was that I had to uninstall and reinstall facebook last night, after it stopped working. Almost all of the complaints I had about CM10 have been addressed. The only one left is the MMS bug.
I also find everything to be smoother and snappier with CM10.1, except for opening texts, which is somewhat slower, but not too bad. Battery life is substantially improved, and I'm not even turning data off now. Power usage is reduced to the point where my battery actually charges when running navi with the screen on at 25%. Before, it would hardly charge with navi running and the screen off. That is with a 2A charger and an Apple type USB cable so the phone sees it as an AC charger.
At this point, I am so happy with my Epic 4G that I see no reason to upgrade it.

I've never tried that before, but just installed Bluetooth File Transfer and wasn't able to make it work. Not sure if the problem is my Apple computer though. My PC doesnt have BT.

Agreed I will use this build until the wheels fall off.
I wound up flashing the nitest kernel and Nexus S 4G modem and the experience gets even better.
I like it so much now, that I just picked up a new Epic on Ebay to replace my current one, which has over 2 years of battle scars on it and some button issues.
Hope someone can help me solve this issue.
The Setup
I recently went out of the country and before I left I unlocked my GS4 following from wonderhowto[dot]com
Arrived to my Carribean destination, bought a prepaid SIM, popped her in and everything worked great.
Problems started when I flew back into Miami. I removed my prepaid SIM and installed my old one, changed my APN name back
and rebooted the phone. Decided to plug it into my laptop (USB3.0) to get some extra juice before the next flight and I noticed that
the battery was actually going down and quite quickly too, about 1% every 3 minutes. The phone was also doing a lot of connecting and disconnecting from the laptop even though it was not being moved.
I use two batteries which I have an external charger for , so this didn't slow me down too much.
After a few days, I thought maybe by unlocking the phone I had left it in some "roaming" state where it was eating up battery looking for its signal, so I decided that I'd restore it to the nandroid backup ROM Manager created before I did the unlock procedure. OH NUGGETS!
Things got ugly , quick!. In the process of trying to restore got MD5 mismatch error, so I went back to 3 previous backups before all of which said either "MD5 mismatch" or unable to open .zip -None of them worked.
Thankfully I had saved a copy of the backup folder in clockworkmod to my PC and tried to load that, it started and then get to writing /data and said error writing data.
I rebooted. Bootloop.
After a few hours of attempts with KIES, and some well timed cold beer deliveries from my wife, I finally got the phone back to stock version.
Rooted it again, motochopper, And loaded GoldenEye Rom v 8.0 . Still slow to little or no charging.
Loaded PACMAN and noticed something that should be mentioned.
Pacman rom has its own little battery widget that sits in the top tray and shows the %. It glows green from bottom to top to show that it is charging. I noticed on every couple of cycles, the battery meter would flash red for a quick second before turning green and sweeping up.????
Went back to a backup of GoldenEye8.
The current status
The phone is currently plugged in to the stock charger (2A) and stock cable. It has charged up only about 3% in 20 minutes time. I have it in battery saving mode with wifi on , and EVERYTHING else turned off.
Battery info says:
Temp 87.3 F
Voltage 4033mV
Plugged True
Charging
Li-ion
Health:Good
Charge Type : AC
Battery use shows 62% of battery use coming from SCREEN (Yes I have auto-brightness set, and NO live wallpaper)
Anyone have some good input?
Maybe its a bad cord? Or bad USB port/connection on the phone it self...

62% screen usage is normal, I sometimes see over 70% with my brightness all the way up.
Make sure apps aren't keeping it from going idle and staying active.
Battery temp. seems a bit high. General causes of that are a faulty cable.
Download greenify and hibernate any apps that may be running unnoticeably in the background.
If your kernel allows fast charging (disables access to phone storage while fast charging is on) enable it while charging if you're not using the phone.
Play with CPU and GPU governors in your kernel to save battery life. I.E: I put my CPU governor on "powersave" while idle and not using the phone for anything extensive.

Tried two other cords,but they just made it worse. They actually caused it to look like its charging but the battery level was going down.
Your second suggestion is probably right, but i'd like to exhaust my options first before having to restore and send to creator. I do find that with the stock cable and no external case on it stays plugged in well and doesn't make any "interrupted connection" noises.
With stock charger and cable and minimal functions running its charging about 1% every 4 minutes. ( Approx 6.5 hrs to full charge )
I feel like the hardware must be working in order to do that, and that the software is putting some kind of excessive strain on it. Possibly?
The battery use still shows, screen as the major contributor at 61% , so I switched from a really high resolution static background to a low res one. ( results to follow)
Downloading WanamLite now and going to try that out, also going to try performing the unlock procedure I did in reverse order and see what that does. Keep you posted. Open to suggestions.

Thanks for the advise, I'm running greenify and its really only showing facebook and my sms app, I hibernated facebook anyways just to test it, but I know out of the box , on a car adapter this thing was charging 1%/min , maybe I have a bad ROM/Kernel mix?

Doubt it, but maybe you can try going from touchwiz to aosp. Very much more lightweight, though you'll lose some s4 features. If it is faulty hardware/battery I'd just save yourself the trouble and swap it for a new one; or try another battery. I guess you can try doing a compete wipe and flashing a fresh ROM with a kernel you know will definitely run smooth with it.

Already tried the second battery, no luck. Any suggestion on the rom/kernel combo?
I use task650 with kt's kernel and it's excellent. Though it's all opinion, there is many great combinations. Some ROMs come packaged with their own kernel or a custom one.

IMO: those temps are pretty normal.
Why you don't try a bone stock rom and see how it respond for a few hours, if the stock rom behaves the same, probably you will need to send it for warranty.
Hello to all!
Since I don't have honor to post on main development page I need to post here in question!
I can't find nowhere something about battery life, I installed without problem ROM on my SIV and battery life is very poor. Yesterday I watched on YouTube MKBHD Hangout with Motorola CEO Dennis Woodside which have length of 39 minutes I think. My battery was at star 98% and at the time of ending video vas 45%. Battery can't last full day of normal usage. (it last from 07:00 to 18:00). At beginning I noticed this problem and I installed One Power Guard and its always on powersave or standby mode.
This anyone facing with this problem?
Yes mine is exactly the same. Running v4.0 and battery life is terrible now. Camera app force closes every now and then and sometimes maybe twice a week it reboots.
Plus I can't charge it switched off - everytime I plug it in it starts up.
Hi,
My battery is a little poor too, but it was because I was with my cellphone screen on almost the whole day... When it was an extreme case (when I was in 4.3 AOSP ROM and it didn't last even some hours, like you), I recalibrated it (I used to do it with my Xoom and X10 Mini Pro, it may be a placebo, but looks like it worked...
To recalibrate simply let your battery run completely out, then plug to the charger and let it charger completely while turned off (the white battery icon appears), then turn it on and let it run out again, then charge fully again. Remember that plugging and unplugging your device from the charger is bad for your battery, and remember to keep the screen brightness very low, turn off WiFi, Bluetooth and SPECIALLY 3G when you're not using.
Hope this helps,
~Lord

You need to flash v.6.0 which mostly correct FC camera app. I notec when i was runinng on ART reboots was more common.
My solution was to flash MK9 stock rom, this is the most stable and reliably by me so far.

Thank you for advice. I was using battery calibration on my Galaxy SI GT-i9000 and Xperia X8 and it was uselles. Know i didn't se enyware that i need to recalibrate battery so i didnt do that.
