So my gf's Nexus 4 is having some issues with the phone - on idle it drains in 8 hours, and it seems to charge very very slowly.
I tried connecting to the computer to copy off settings and photos but Windows is telling me in device manager, "Device Descriptor Request Failed". It's actually draining faster than it's charging when on USB (but is fine on AC, still very slow though).
Was using ART.
Has anyone else had a similar problem?

Already done all that - underclocked and undervolt, still no improvement. BBS installed as system app with root, showing no wakelocks (highest one is 8 minutes).
1. drain: can be a kernel related or os problem, so flash a new kernel, or reflash your current one, or flash another customer rom or stock
2. slow charging: you should try another USB cable, on my old HTC cable my phone is charging about 33% slower!
.. or it is charging slow because of the drain.. hmm, think last one
3. what do your battery stats tell you?
keep calm and push the thanks button!
I restored my phone back to factory Kitkat last night, and overnight there was 3h of constant battery drain under Google Play services.
Might downgrade to 4.3 and see if it's still there.
Might be the battery is having some problem. Contact google if you still have warranty then ask for replacement.

It was bought on launch day - out of warranty now
I don't think it's a physical thing though.
Check system internal battery status, to see who uses battery. And also check if wifi, gps, etc are always on.
If RF, Android OS, etc uses most, and battery drain fast, try another ROM and Kernel also baseband firmware. If app uses a lot, uninstall it and have a try. Disable wifi, gps, etc.
If you can, try charge your phone from shutdown, where no app runs. It should be fast, otherwise, some hardware should be replaced.
Did a factory restore from the Nexus image, just left it idle with Wifi on and no other apps other than the default Google ones, and it still drained itself after 8 hours.

Ive recently installed jokerdroid4.2 and have suffered some crazy battery drain. Pretty much every night if it isnt charging and left on battery, by the time i wake up ~50% of the charge has gone - last night i left it at 97 and this morning it was 53. Is there anything i can do to sort this issue because i never had it on cm7 and actually had great battery life on that. Thanks
fix = uninstall task manager and when charged at 100% (still plugged in to charger) download battery calibration app from market and do battery calibration. after that give the battery few full charge/discharge cycles (charge it to 100% and dont charge until battery dies and phone turns off). do that after flashing any rom. if that doesnt work, its a hardware problem prolly.
hit thanks if i helped u.

How does that help ?
He is saying battery is drained quickly, not that battery values are wrong.
There are apps that shows which software has consumed battery and by how much. Check in one of those list. If you haven't started using any new heavy apps then problem is related to basic functions like Mobile Data Network or WiFi or Cell Tower Signal etc.
Fix for these problems should be listed out by devs, but choose to ignore.

Plus, you dont need additional apps, any "monitoring" app just drains battery. You can check in settings.

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~!
Hi all! I've had my note for about a month with no problems, but last night it went flat in 11 hours of no use.... The battery use screen shows that it was the OS with nothing else running!
I have this problem too, really need to know answers!
Do u leave ur wifi,packet data, gps and Bluetooth always on? This may be the problem,just use any battery saver tools and close unnecessary hardware

but i always have the same settings - why such a sudden drop in battery life?
Check if you are in 3G mode or 2G.... 2G save a lot battery

Installed anything just before the drain problem?
Pretty much all the problems I've had with battery drain have been traced to an app misbehaving. The battery stats info can be a bit misleading too - so don't trust that the OS itself is draining the juice... Its more likely to be some service app that doesn't show up a itself on the stats.
I've found Widget Locker a painful battery hog, for example, but it never shows up in my battery stats. Instead the Android OS, or whatever last write to the system log (log cat) show up as using all the power. Uninstalling WL always fixes the problem so I know its that app causing the drain.
Also, is that shield in your notifications bar some sort of battery saver?
If so it may be the cause not the saviour! I've read that the latest free version of Green Power tries to connect to ad-servers constantly and drains the battery double-quick. Apparently the premium version doesn't have this issue but you have to pay for it, obviously!
the issue is undoubtedly running services..you probably added an app or three that is high maintenance.
shut down and restart your phone and then without starting or using any apps, leave it overnight to get a better benchmark for battery life.
If still low, look at the running services, you may be staggered to see what amount of crap is running in the background..

how do we find what services are running?
Mine hasn't had any new apps installed and normally loses about 7 percent overnight. The shield in the pic is lookout which I've always used without a problem. I have restarted the phone so I'll see how it goes today. Its wierd because nothing has changed in use or apps so something must have hung and run it down.
I'll post any other findings!
Thanks

just done a hard restart
turned off wifi
removed weather widget
removed live wallpaper

some tips for better battery life.
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.
I'm using CM 11 (4.4.2) and MKernel.
As the title says,I am experiencing massive battery drains for no apparent reason.I charge my tablet at night (because it doesn't only discharge instantly,but also takes forever to charge - even if i'm not using it),at 12,I unplug it at 5-6 in the morning,and when I get back home at 2-3 it has 40-60% battery left.Not to mention how fast it discharges when I use it during the day.(like 1-2% per minute when I am just browsing)This shows in android: http://m.imgur.com/ZxxQZFu and this in gsam: http://m.imgur.com/UecetMU,BEa31nR,azM4kqq,DS5Ts3e,Sz5PQYv (i know,custom kernel,but the stock one was draining almost the same percent).I've disabled some gms services with android tuner but I dont't see a major change.FYI: my location ,location history,sync are always off and thre brightness is almost always at 0% and I don't have any rouge app. Any ideas what could it be?
BTW: Does anybody know what (wrong) service I disabled because no google app is able to connect to the internet anymore.

Those screen shots aren't the helpful ones. You need screens of held awake time, and times waking device from Gsam. The main Gsam screen is helpful too.
....and you need Gsam root companion installed to see those wake screens.
