This is my first android phone and I'm wondering if I am doing anything wrong. Yesterday I charged my phone and it was at 83%. I unplugged the phone and went to sleep, when I woke up this morning the battery was completely drained.
This happens a lot. Even if I am not doing anything it still drains like crazy. I just text, make some phone calls and it barely makes it through the day. I don't play any games, no gps, no Bluetooth or anything. With my plan, I don't have a data connection so I can't connect to 3g/4g so that shouldn't drain anything.
What could I be doing wrong? When I'm done using the phone I tap the power button on top, the screen goes black - to sleep I presume and I put it away. I had an iphone before this and I did exactly the same thing and the battery lasted for 3-4 days on one charge.
Whenever I see what's using up the battery, the display tops the list. The display is using up 75-80% of the battery. If the phone is asleep for most of the time why is the display using up that much battery? Am I not putting the phone to sleep correctly?

If you cant connect to 3g/4g, you should turn it off in settings. Otherwise, Your phone will constantly look for a signal, draining your battery.
Battery life is all relative. Every single person will experience different battery life. The apps you have installed, the amount of time you spend on it and the time you spend on/in each app, distance from cell towers, distance from Wi-Fi sources, settings you have for every app and things like sync and what not.
The first thing to check is if your phone is being affected by the init or suspend bugs. The good news is the former has an easy fix, and the latter can be temporarily fixed by a reboot.
First, download & install Watchdog Lite from the market. Then open its preferences and check "include phone processes," "monitor phone processes," and "display all phone processes." Then just use your phone as normal. It may take a while before you get an alert from Watchdog (and maybe you never will and it ends up you have a different problem). But if you do, note the process that is the culprit.
If it is the init process, go to settings>applications>development> check "usb debugging."
If it is the suspend process, reboot the phone. It should keep it from happening again for a while.
I know the second answer isn't really an answer, but so far it's all we've got for that problem. There is more information on the 2 problems in these threads:

Good luck...I had both of the problems and my phone didn't last to dinner time. Now I get better battery life than the iphone 3GS I had before this...about a day and a half of moderate use.
EDIT: also you'll probably want to go to settings>wireless & networks>uncheck "mobile network" since you don't have a data plan. No reason to have that on since you don't have a data plan.

I installed this using the Moderate setting, and then selected those options as recommended in preferences.
Does Watchdog use a lot of system resources when running in this manner? Will it cause the battery to drain noticeably faster?

Completely unnoticeable, IMO.
I installed watchdog lite and I have had couple of alerts. I got suspended couple of times and I also got Android system once.
Android system - 50.1%
Foreground
Suspend - 54.4%
Linux Process
I turned off the data usage from the settings and it did help save battery. The display is not using so much battery life anymore. It went from using 70% to 35%.
Edit: Battsatt reported that the battery was at 93%. When I saw the two alerts above I rebooted the phone and Battsatt now starts reporting the phone is fully charged.
Make sure the GPS is turned Off, too...
All these answers and the easy ones were not mentioned..
Make sure you shut your AUTO SYNC off...
Make sure you lower your brightneess....
Make sure you turn off GPS(was stated above me)
Turn off your wifi if you are not using it.. make sure you are not transmitting your hot spot stuff...

You just summed it up right there. You are experiencing the 'suspend' issue, period. There is no app you can install to fix it. There is no app you can uninstall to fix it. There is no setting you can adjust to fix it. There is no fix for the 'suspend' issue, literally.
I started the following thread in an attempt to consolidate posts and hopefully work toward flushing out what the real issue is...
http://forum.xda-developers.com/showthread.php?t=872839
This is a real, legitimate issue with Android 2.2.x Froyo. As I linked in my post, this is Issue # 11126 on Google Code...
http://code.google.com/p/android/issues/detail?id=11126
If there was an app or setting that fixed the 'suspend' issue, we wouldn't even be discussing this right now. There are fixes/workarounds for a lot of things, but right now, the 'suspend' process issue truly is a mystery. No one, not a single person has yet to post, "this is the cause of the issue," let alone a fix for it.
I wish you had a fix man, I really do. My fiancee experiences this and there's only one way she's found to sort of workaround it, sort of - she reboots her phone every morning. This seems to keep it at bay, at least more so than when she doesn't reboot each morning, once she takes it off the charger. She still gets it though and she's just used to looking for Watchdog and checking her processes now.
This thread could go on and on forever but it comes down to this:
- The MT4G does not have insane battery drain and will give you about 12 hours of life, under normal>medium usage. If your battery is draining insanely quickly AND if you're seeing the suspend process jacked up so high, then there.is.no.fix.yet.
There might be a ton of other replies after this about uninstall this, install that, change this, don't use widgets, use widgets, etc. Those attempts will be futile.
Prior to ICS my tf101 would last a good 3-4 days on a fully charged battery with my normal usage during the week. Yesterday I installed ICS went to sleep with just over 50%, it had suffered some heavy usage yesterday, and woke up to a completely flat and switched off tablet this morning. This is very unusual performance for my tab.
When I installed ICS I did a factory reset to clean up my tab so only have a pinch of the apps I had previously installed. One thing I did notice is on the battery tab of system settings the tablet was awake 100% of the time were traditionally it would only have a blue mark were it was in use on the awake line. Battery usage data is unavailable, too, so cant see what is causing tablet not to sleep.
Any suggestions?
I would wait until it settles a bit more, plus wait for a custom rom. It probably has some bug, seeing as it is the first ICS for our device.
I also notice some battery drain last week
on HC and ICS
right now i reverted back to honeycomb
ill update you later
if anything changes to me
MyZine Widget
Got rid of the MyZine widget and my tablet now goes to sleep in standby. I noticed, when browsing the running apps list, that the app kept 'restarting' so it could buggy or at the least was having a problem with my tab.
Prior to ICS my battery drain was crazy, especially if I leave wifi on. Not anymore, it's back to normal consumption like I had before the last HC firmware update.
I had the same problem this morning.
take cpu spy to have a look if the tablet goes into depp sleep.
https://market.android.com/details?...251bGwsMSwxLDEsImNvbS5idmFsb3Nlay5jcHVzcHkiXQ..
i had to reboot and then everything was fine...
I've still got problems with my tab. Returned to it after a few hours non-use and it had shutdown itself. Battery Drain still seems an issue too. I'll install that app and see what it reports.
Check WiFi disconnection policy and if GPS is disbled.
Here I am trying to get answers to exactly the op's problem. Everything went smooth installing ics. Even wiped data.
Woke up this morning to a very dead battery. Went to sleep at 83%. Interestingly, the battery graph show nothing after about 80%. No indication on the graph of total discharge...and no app usage. Just straight from 80 to zero.
I can't determine if it's a hung app or what....I've installed almost nothing. And it looks like the tablet drained while it was OFF!

Sorry for the link....I could not get the damn picture posted for the life of me...despite 45 minutes worth of my time.
i also woke up to a dead battery this morning. it was 50%+ when i left it on standby, wifi & gps switched off. i would have expected minimal drain on HC.

Try this
Go to settings /WiFi /click three dots in upper right corner/Advanced/ uncheck keep wifi on during sleep.
go to recently used apps and close all ( swipe to right)
put tab to sleep for a while
Come back and turn on.
go to settings
battery
tap grey battery level graph to expand
check individual bars to see what was on and off.
Looks liks some apps are keepi9ng WiFi and GPS on and draining battery.
It would be really nice in future update to have a setting like below:
Setting
Sleep setting
On screen off close all apps except ( here you get to choose apps to leave open)
I'm glad I am not the only one with battery drain issues. I thought I was doing something wrong.
Several days ago I charged my dock and tablet fully. I then turned off the tablet, closed the lid and didn't use it for a few days, when I went to run it again it was totally dead. I would have expected it to at least hold something of a charge in a completely off state.
Yesterday I left the tablet and dock on but just turned the screen off and again this morning had a drained dock.
Just seems like no matter how I try to settle on a way I still see more of a drain than I would have expected.

I will have to take a look at that setting myself and see what is up with it.
Yes, it would nice to have a sleep setting button for some helpful settings.
Have there been any firmware updates for the dock itself, or is that not possible?
I'm having the same issue dock was at 80% last night get up this morning and it's at 6%. I set wifi to off during sleep to see if that helps any.

Have to close apps that are keeping stuff on. Look at permissions. More and more are adding "prevent "Function X off during sleep."
As soon as I got the update installed I turned GPS off and set WiFi to never sleep, woke up this morning to only 4% battery drain. The tablet went 12 hours and went from 40% to 36%, i also had apps open...
apps open: engadget, camera, browser, gmail, market and settings..
no battery drain yet, updated yesterday and only 5% drain during the night with apps open
Help!
Same problem here. I noticed high battery drain yesterday and didn't think to leave it plugged in.
This morning, it wouldn't turn back on! I've left it plugged in in case the battery drained too far and will try to turn it on later on.
With HC, the power button was buggy (had to press really hard) and seemed that that went away with ICS (well except for now). Don't know if this is related.
Same issues with me. Except my tablet won't wake up when I push the power button. I have to hold and reset it. Here is the kicker: I will get a 20% power drain over 9 hours on top of it. So not only does my tablet not turn on after it being asleep, but I get a power drain as well!
My Settings: Stock ICS off a completely reformatted device, Keep Wi-Fi on only when plugged in, screen timeout is 1 minute and MobileDock Battery Saving mode is on. My battery usage indicator does not work... I have to get the very basic info from my battery widget.
Very disappointed! This was the one thing I wanted fixed the most. I hated using the airplane mode app. It severely affected performance.

Maybe we are all having the random reboot problem.
It makes sense if you think about it.. Mine would randomly go into reboot in sleep and the device would get stuck on the Asus loading screen. So when the device cycle through the loading screen for an entire night, you would find a dead tablet by the morning.
So far, I have encountered 2 random reboots, the only way to bring the device out of the boot screen is to hard reset it by holding down the power button.

balor you most likely got better battery due to custom rom
custom roms tweaked the battery for couple days use.. asus claimed like 9 hours on the tablet.. and like 19 with dock keyboard. custom ics roms inc
Every night, my battery is drained by 7-8% even though, GPS, WiFi, all radios are off and the phone is in airplane mode (done automatically via LLama scripts). I installed GSam Battery Monitor to try to figure out what was going on and it indicated that even though the screen was dark, it was draining the battery (and was the primary culprit). Is this accurate or is it a bug? Anyone else seeing something like this on their Nexus 4?
Mine shows 78% usage in dark.. I think that just means how much of battery total it was used while the phone screen was off. I'm taking a completely random guess here though.

So you reset the app right before going to bed and checked it first thing in the morning and in the 7 hours you slept, the main battery drain came from the screen?
I use the same app and I never noticed anything wrong. Still, battery readings are not always accurate... sometimes when I recharge my phone, it stays 100%for a few hours, then it drops 7-10% in a matter of an hour...and that's completely normal I say you shouldn't worry about it too much as long as you get satisfying usage times..

I'm not happy w/battery life and trying to track down what the culprit is. If all major services are off at night, 7-8% battery drain doesn't seem normal to me. Granted this is apples and oranges, but my iPad Gen 3 in the same configuration remains at 100% overnight.
If doing nothing drains nearly 10% over 6-7 hours, no surprise I've got issues during the day.
I've noticed the same thing, one time I didnt turn the screen on on my phone, then I went to screen and it showed 0% discharge while screen on, and 7% discharge while off. I'm running the latest version of Viper, I'm also confused and I wonder if theres some issue where maybe power is being sent to the screen even though it's not on.

After my 7 hours sleep.. Every morning my phone uses 2% battery drainage at MAX. i.e.: Wifi Edge Sync etc ALL OFF. And I am getting 4+ screen time on my phone with moderate usage. Pretty happy with the battery life so far.

Your phone probably isn't going into sleep. The Nexus 4 seems to be prone to insomnia caused by apps that don't cause a problem on other devices.
To check this download CPU Spy from the play store. Run it, reset timers to zero, and with the phone on battery (i.e. not on charge) let it rest for 30 minutes or so, then check the figures.
You should see Deep Sleep as > 90%, if not, or it is listed as an unused state, your phone isn't sleeping.
To fix this you either work forward or backwards!
Work forward:
Factory reset, install CPU Spy, run the test and see your phone is now deep sleeping.
Start installing applications one by one and after each install, run the app, then run the CPU Spy test again.
Eventually you will find the app causing the problem, all you can do is avoid that app. Note you may have more than one app causing a problem so keep checking after each install.
Work backwards:
Start by un-installing an app at a time restarting your phone in between then running a CPU Spy test. Start with any live wallpapers (even if not set to be used) you have installed, then any weather widgets. Note just un-installing is not enough, you must restart after each one.
Eventually your phone will start deep sleeping again so finding the problem app.
Hope that helps.

Phil
I tried your advice, and my phone is going into deep sleep around 90% of the time, so I don't think that it's a rogue app. I keep my phone on the dimmest setting at all times, and I only get 2.5 hours of screen on time. I have an anker battery.

So, yesterday I noticed a sudden battery drain on my nexus 4. After checking battery it showed that AndroidOS takes over about 50% of the battery usage. It also showed that time awake was pretty much the same as the amount of time since I unplugged the phone, even though I kept my phone in sleep mode for the most of the day. After some research I downloaded better battery stats and it showed that from the moment I turn the screen off a process called suspend_backoff runs pretty much the entire time. Eventually I got it down to wifi. If I turn off wifi there are no processes running after the screen is turned off (or if there are they are 30 seconds tops), but the moment I turn wifi on suspend_backoff runs pretty much the entire time screen is off. I tried removing all of my apps, as well as doing factory reset but nothing helps. The moment I turn wifi ON this suspend_backoff consumes pretty much all the time during screen off period. Is anyone experiencing anything like this ? I have 4.2.2 on the phone and I havent' seen this extreme drain until just yesterday.
I experience the samething. Android OS would drain as much as the screen time.
I narrowed it down to the suspend_backoff. But the weird thing is that when i'm at home on my home wifi, suspend_backoff doesn't seem to drain anything at all. But when I'm at school, suspend_backoff kicks in.
Anyone help?

how did you narrow it down? Im having the same problem!
This is caused by a kernel wakelock. A bad mobile connection make battery drain worse... using WLAN nearly fixes this problem.
Thought this problem has got fixed in 4.2.2, at least battery life got improved and the wakelock reduced.
If it is appearing since yesterday, it is triggered by a app often waking the phone up using mobile data (that's why fixed with WLAN) and prevent the phone from getting into deep sleep as fast as it should.
hope i could help.
I use Greenify to hibernate every single user installed apps, then I release them one by one to see which one cause suspend backoff. But suspend backoff still occurs. So I think it's the kernel itself.

Yeah, definitely not user apps. I did full reset on the phone to factory settings, no user apps. Even tried disabling Google Play and Google store after the reset. Still the same. The only thing that gets rid of it is disabling WiFi.

Yeah, it's clear that it's the wakelock. What's not clear is why. Also it's not the msm_hsic_host that the forum link you sent refers to. I don't have a problem with msm_hsic, that one barely takes any time during the day (maybe 30 seconds during several hours of standby). The wakelock causing this particular issue is "suspend_backoff" wakelock which supposedly happens when there is a sequence of sleep/wake calls too close together so the system decides to keep it awake. I was unable to find what exactly is causing the issue, even after restoring to the factory settings I kept seeing the same problem.
Anyway, I was able to "resolve" it by installing JuiceGuard app and setting it so it disables wifi when the screen is off. wakelock is gone now and my battery usage is back to normal.
I only get the suspend backoff wake lock when I'm connected to the university Wifi. When I'm at home, everything is fine, no suspend backoff. So my guess is that the Wifi encryption at university is different and causing a succession of close "awake" and cause wake lock.
I did factory reset like 3 times and it still there.
I'll try disable Wifi on Monday and see how it goes.
Same here, when wifi disabled the wakelock doesn't occur.
I have tried almost all of the kernels and non of them seem to help.

Interesting... Maybe it is encryption. One thing with my Wifi is that it doesn't use password, but MAC list instead. It may indeed be an issue with different wifi encryption types.
OP do you have maps 6.14 on your phone? Mine kept switching on location reporting for a while and it woke my phone 344 times last night. I've been struggling with the same wake lock issues. I'm going to recharge (again) with maps disabled and see if that helps.

The clowns may have left you a lovely gift there without telling you or asking any kind of permission.
The latest Maps was giving me horrible battery drain, on WiFi. I'd sleep for six hours with a fully charged phone and wake up with 10% left. it even enabled itself when. I disabled it in settings. I converted it to a user app by moving it to /data/app and greenified it. Seemed to have solved all of my issues with the suspend back off wake lock.

For some weird reason, I was also having serious battery drain suddenly since yesterday.
Turned out it was maps, and disabling Google network locations hugely increased battery life

For a month or more I'm facing totally unexplainable battery drain.
As seen on the screens below, the phone is awake, but it is not detected anywhere - not by android nor by GSam. In any case the battery draws faster.
I have one observation tho - this happens after I make phone calls. Not every time, but once per 2,3 days.
Any ideas?

I have one observation tho - this happens after I make phone calls. Not every time, but once per 2,3 days.
Any ideas?

You have this problem

I'm pretty sure that I don't have this issue. Yes, the percentage in GSam maybe high, but I don't believe this reflects what is happening.
First of all - I don't have bad battery life. Usually my over night drain is less than 1%/1h.
Second - the issue appears sporadically.
Third - in the provided thread I don't see the issue appearing in stock battery monitor, while mine appear.
At last - my battery drains faster only while the issue is present and before I restart. After that it is back to normal ...
@Spo0f
Just some suggestions maybe you're using 3g I always have that turned off and switch it on when I use it my guess is that some apps are causing your drain after a call maybe like you said if you're not fimiliar with greenify I suggest you use it to stop all those apps and system apps also uninstall all those bloatware you don't need or at least freeze them if you don't mind lower the resolution to 1080p with nomone app use power save or disable dvfs and use an app to lower and raise the CPU to save juice when not needed....
Thanks for the suggestions, but as I said - this problem appear sporadically - home when using WiFi as well as outside when using 3G.
All of the rest is done - I'm no newby

Oh sorry mate well I don't use much 3g so I can't help you there but if you're having drainage when you're using WiFi in general then maybe you should reconsider investigating the post above with the link I don't have so much drainage on connectivity with 3g or WiFi....viewing the pics you uploaded it seems suspicious.... Maybe an app? I don't know...
Use wakelock detector

My overnight drain was also very low, but that was because the faulty device on the network was asleep at night too (my desktop).
If you're not rooted, use the PC version of Wakelock Detector at the end of your day and post screenshots of your highest drainers for the various categories. In my case, the device was being woken up by something on the network and it showed.
Bear in mind that actively downloading something in the time period will also raise wifi power used but more stats will help.
The fact that you're still experiencing a lot of drain even when outside suggests it might be a rogue app
One phone call today and after it the phone stayed awake.
Because I had issue with the PC WLD the screen shots are from 11 minutes after one of the disconnects. The device was awake all of them.

I also checked out my battery behaviour this night and was very disappointed. Although my phone was in flight mode and every peripherals and services shut down, today morning my phone was crying for energy. So I made a quick investigation in my power diagram and found out, that "Android OS" requested a wakelock during the whole power-on time. So I installed "CPU Spy" to check in which states the phone was really over the whole charging period. I couldn't believe my eyes. Although the kernel should do it's job good, cause most of the CPU times are in lower freqeuncy states, the deep sleep mode was never activated.
Therefore I installed an app called "Wakelock Detector" to check out which apps could cause that. I found out, that S Health had a big amount of wakelocks and also active-time, so the first thing was to disable S Health. After some minutes I checked back, but nevertheless still no deep sleep time in "CPU Spy".
So I searched around and found another one arguing about the wakelocks and that they could be the products of some programming issues concerning WiFi. The should be gone, after turning off WiFi and rebooting yout phone. And it seems that he was right. I waited some time and hooray, "CPU Spy" listed the phone state "Deep Sleep" the first time as an active state and also with the major active-time. So at least that was some step ahead. (I have to remark, that S Health was already unfrozen at this time, so S Health should not be responsible in any way.)
The next step was to reactivate WiFi, leave it on and set the phone on standby. After some time I checked back again the phone showed even more deep sleep time. So that was an improvement. I reactivated everything and waited some time... Deep Sleep all over the time. Can't figure out for now, if it was S Health, WiFi, or anything else that caused the wakelock for sure. At least the reboot helped. I'll check that out on a long-term test, maybe I get some further conclusions.
