I used to have between 20 to 30% wakelock rate with stock soft (2to3h screen). I'm now on faux kernel having an average of 10 to 15% (4to5h screen)

Carat changed from 21 J-score to 71.

I'm quite happy now with my battery life.

My settings:

Gnow OFF

G+ OFF

Cell Broadcast OFF

Less apps syncing

Increased time between syncs (mail, gmail, evernote, ...)

[Nexus 4 Q&A, Help & Troubleshooting] yokuyuki:
So basically, you crippled your phone for more battery life. That's not surprising.

So I tried an experiment yesterday where I idle overnight with airplane mode on and wifi on. I ended up reducing my kernel wakelock, but it also ended up causing G+ to keep my phone awake the whole time which is odd because it should be able to sync just fine over wifi.
[Nexus 4 Q&A, Help & Troubleshooting] Juduth:
Yup, I find the kernel to help just a little

Quite weird. Had a similiar issue some nights ago but with gTalk. It continued to produce wakelocks despite being disabled in app settings O_O

I've been without wifi for a few days and I started getting this bad. Like, zero deep sleep some times. I tried a few different kernels which helped a little bit, but then just on a hunch I decided to leave wifi on. Even with it not connected to anything, it reduced this wakelock to be pretty much nonexistent. Clearly a bug.
[Nexus 4 Q&A, Help & Troubleshooting] yokuyuki:
Seems like all different issues for us. I have wifi on overnight all the time and I still get a ton of wakelocks. Also have Google+ off.
[Nexus 4 Q&A, Help & Troubleshooting] calanizzle:
which wakelocks ?
[Nexus 4 Q&A, Help & Troubleshooting] remydlc:
im in a place with bad reception, seems i only get edge here, and that wakelock kill about 20% of my battery in 2 hours...! 30% of them, i turned off 3G so let's see.

update1: in just about 20 minutes, it has gone down from 30% to 28%, that is the wakelocks. I think this has something to do with phone radio and data transfer/communication.

update 2: down to 20 pecert about 80 minutes later. So i think this has something to do with the reception, if there is good reception, you wont get this much.
[Nexus 4 Q&A, Help & Troubleshooting] spinkick:
Remember, this is used every time your radio is used, so, it's gonna show up more if it's trying to make connection, sync data, etc. The problem. That the wake lock lasts much longer than it should, not that it occurs.
[Nexus 4 Q&A, Help & Troubleshooting] remydlc:
but if you have a bad conneciton, that means no data will be synced, and then the more wakelokcs are gonna be issued to get the device synced up.
[Nexus 4 Q&A, Help & Troubleshooting] spinkick:
Sure, but it's not the wakelock occurring that is wrong, just the bugged duration
[Nexus 4 Q&A, Help & Troubleshooting] calanizzle:
Again, wifi on decreases this wakelock..

This wakelock is ridiculous, Google really needs to issue an update to address this soon.
[Nexus 4 Q&A, Help & Troubleshooting] arvonn:
I still have this wake lock' but it no longer drains any battery before I could only get maybe six hours of total r run time. , by doing several things, turning off location updates, and google plus background sync, currents sync, getting rid of flipboard, and running faux 123 beta 2 build 8 kernel, rooted, otherwise stock. Now I have maybe 1% drain overnight, eg if I leave my phone on at 50 % when I go to sleep at 11 pm, it will be at 49% at 8 am.

So now I can get a full day of normal usage.

I do have T-Mobile as and a Cel-fi to boost signal, so I can leave Wi-Fi, and data sync on overnight and not have any problems.
[Nexus 4 Q&A, Help & Troubleshooting] Michealtbh:
I also have this wakelock, it usually shows as using 20-30% overnight. It doesn't seem to actually drain much battery though.
[Nexus 4 Q&A, Help & Troubleshooting] stevemw:
Thinking back to my multiprocessor programming days this could be an inherent factor in an operating system on a multicore device when job are spit up to run on more than one CPU. The job has to wait until all partipating cores have completed processing their subtask to put the various pieces of the job back together. The process used was called "waiting at the gate." When all pieces of the job have arrived, the gate opens and the next job can run. The impact may have been negligible on dual core systems but is multiplied on quad-core or more systems. Programs have to be tweaked to determine which jobs can be broken up and how best to schedule them so that the wait time at the gate is as close to zero as possible.

Apps add to the problem

Any apps that cause additional wakelocks, things that poll at a normal interval, facebook, twitter, words with friends etc make this issue much worse, I usually have a lot of apps installed and with everything I normally install I was losing 6 - 8% an hour when idle.

I recently rooted and haven't installed any apps yet and my drain while idle is 1 - 2% an hour when idle.

This device definitely needs to be patched, their shouldn't be as many wakelocks and they shouldn't consume the amount of battery they do.

The problem is most likely software related, I just checked my SGS2 (work) which is running one of the latest cynogenmod 10.1 builds and that phone sits idle almost all of the time. Android OS is currently similarly eating 52% of the battery, battery life has really tanked since I upgraded the device from ICS. It might be Android 4.2 itself that has the bug.

Out of 1d 1h 28 mins, Android OS has kept the phone awake 1h 48m and this phone lies idle 99% of the time.
[Nexus 4 Q&A, Help & Troubleshooting] Mindspin_311:
I dont think its a 4.2 thing. My LG Optimus on 4.0.4 has this as well. It is continually in the 10-20% range depending on how much time I spend OFF wifi and on 3G/4G.

So here's something to add:

I've been messing around with VoIP since I've been trying the T-Mobile $30 5gb plan this month.

I'm using gtalk and pbxes.org with csipsimple sip client.

I also created a tasker profile as recommended on the gnex group to turn on WiFi with airplane mode while connected to a good WiFi. Having the gsm radio off for most of the day is a huge improvement to battery life and the side effect is the the wake lock is reduced to 3% or so.

[GUIDE] Smartphone Service for just $30/month
[Nexus 4 Q&A, Help & Troubleshooting] Silverspitz:
How do you explain other S4 Pro devices having better battery performance?

I think it is good to note that the Nexus 4's twin device, which is LG Optimus G, doesn't suffer from the same battery drain issue, despite sporting the same Qualcomm APQ8064 Snapdragon S4 Pro. Battery endurance "idling" tests from gsmarena, may give us some more clues for this issue.

The Nexus 4's endurance test, while running Android 4.2.x, earned a 32h rating:

http://blog.gsmarena.com/google-nex...test-see-if-its-better-than-the-galaxy-nexus/

which is only marginally better than the Galaxy Nexus, which alleged has a poorer than average battery life among smartphones:

http://blog.gsmarena.com/samsung-ga...y-tested-results-come-out-disappointing-test/

Whereas the Optimus G, running Android 4.1.x, LG skinned with bloatware, and LCD screen, manages to earning a whopping 45h:

http://blog.gsmarena.com/lg-optimus-g-battery-tests-are-done-here-are-the-results/

Performing even better than SGS3, which brags the energy efficient Super AMOLED screen and efficient Exynos Quad, only getting 43h:

http://blog.gsmarena.com/samsung-galaxy-s-iii-battery-test-is-ready-does-very-well/

This leads me to think, that whether the msm_hsic_host wakelock is being reported by the battery stats, it may not necessarily be the cause of the actual drain. If it effectively just consume 1-1.5% drain per hour of screen-off idling, then it can be ignored.

Based from the bench marking of Nexus 4's battery performance with other S4 pro devices, such as Droid DNA (monstrous 49h endurance):

http://blog.gsmarena.com/htc-droid-dna-takes-battery-tests-heres-what-it-scored/

it leads me to suspect that Android 4.2 and all the bundled apps, this whole package, is the primary culprit. I mean, how can someone possible explain the efficient 28nm S4 Pro device running vanilla android to suffer horrible battery drain during idling as compared to other Android devices of lower version plus bloatware. The heck, even the aging HTC One X, which the 40nm Tegra 3 plus Sense UI heavy bloat earned 37h on the same endurance test, better than both Galaxy Nexus and Nexus 4, despite sporting only a 1800mAh battery:

[Nexus 4 Q&A, Help & Troubleshooting] sidamos77:
The battery drain idle is only high if you have weak signal.
[Nexus 4 Q&A, Help & Troubleshooting] Mindspin_311:
On my Sprint LG Optimus G, I observed 0.9%/hr drain idling overnight, connected to wifi 100% of the time. If I turned wifi off, or set wifi to off during sleep, I observed 1.2%/hr.

My wakelock % for msm_hsic_host is generally in the 10-20% range depending on how much time I spend on 3G/4G.

Harsh claims to have fixed this in the latest version of his kernel http://xdaforums.com/showthread.php?t=2048739
[Nexus 4 Q&A, Help & Troubleshooting] flx-grafix:
I can definitely say that this is software related!

Never had a problem with this wakelock, until three days ago. I tried different ROM - Kernel combos and was on CM 10.1 and Franco kernel. This combination is absolutely amazing and was running fine... until three days ago. All of a sudden, out of practically nowhere, AndroidOS was always first place in the stats with up to 40% bat usage. No new apps installed, system was like this for at least three days before the wakelocks started.

I wiped cache and dalvic cache, nothing changed. Wiped again and flashed CM10.1 over, still the same.

Today I was fed up with this, made a factory reset and a fresh, clean install of CM10.1... did not yet restore every app, only the ones that I truly need.

Phone rebooted after the installation, running about 1h20m now. Wakelock 1m29s! Problem gone. Gonna restore one app after another to see if it's an app that was waking up my N4.

But for me, this shows, that this issue is software related.
[Nexus 4 Q&A, Help & Troubleshooting] rhoot:
I'm having somewhat the same issue, always after disconnecting the charger. However, if I reboot the phone battery use goes way down. It's only used 15% in 7 hours. This makes me think the issue is *not* with the timeouts (for me anyway) but rather just a software bug.

It's a pain having to restart the phone each morning, but I guess I'll do it until there's a solid fix.
[Nexus 4 Q&A, Help & Troubleshooting] Mindspin_311:
Just ran into these KWLs on my Optimus G. Installed a few camera apps, so I just uninstalled to see if those were the culprits.

sns_async_ev_wakelock - 25%

sns_partial_wakelock - 7%

This pushed msm down to about 6%, when it was in the 12% range earlier
[Nexus 4 Q&A, Help & Troubleshooting] Nuu~:
15% in 7 hours idle is a LOT. It should be at least half of it.
[Nexus 4 Q&A, Help & Troubleshooting] remydlc:
It really depends on what you have installed. I you have apps that use notifications suchlike Gmail, for, twitter, etc it will be more.
[Nexus 4 Q&A, Help & Troubleshooting] pedxing:
Do you have the instant upload feature turned on? That and other sns ( social networking services) activity will increase this lock. Often you shouldn't worry because this lock will increase even while the screen is on. G+ is not good about this.
[Nexus 4 Q&A, Help & Troubleshooting] rhoot:
Regardless it's a lot better than the previous 10% per hour. I'm now up to 30% used in 17 hours of occasional use. Note that I haven't disabled any notifications at all (though I already had NFC disabled), unlike what more or less everyone else in this thread seems to be doing. I've only rebooted.
[Nexus 4 Q&A, Help & Troubleshooting] Mindspin_311:
I have Dropbox set up auto upload photos when on wifi. I was messing with a new camera app while at work and took maybe 4 pictures that auto uploaded.

But, the wake lock on each was for an hour, not minutes. So it seems that maybe DB caused the wakelock? It doesnt quite make sense though because this is not the 1st time it has auto uploaded a photo. But, its the 1st time Ive noticed these KWLs.
[Nexus 4 Q&A, Help & Troubleshooting] yokuyuki:

Right now I'm at a wake lock of 9h 24m with an unplugged time of only 9h 30m. Android OS is at 80% usage and my battery is already down to 32%. Ridiculous.
[Nexus 4 Q&A, Help & Troubleshooting] pedxing:
I've done a couple of tests... maybe others can confirm.

Set a custom reference in BBS and let it sit for 45 minutes. Both Wi-Fi and cell radios on. Got the wake lock for about 15 minutes with no screen on time. OK that's the baseline. Next I did the same but with Wi-Fi off. Similar results. So it's not specific to Wi-Fi. Next repeated it in airplane mode. Still got the wakelock but this time for only 20 seconds. OK so definitely related to data usage.

So now I'm disabling sync services one by one.

I turned off the new alerting service under cell broadcasts and over a short period saw a much better wakelock ratio. I'm continuing to monitor but can others try this and let us know?
[Nexus 4 Q&A, Help & Troubleshooting] sarspants:
Where is that setting?

EDIT: Nevermind, the Optimus G doesn't have this setting
[Nexus 4 Q&A, Help & Troubleshooting] pedxing:
For the nexus 4 folks, it's settings, wireless section, more, cell broadcasts. Uncheck all.

Update: disabling this seems to help. Going from 25 - 30 % wakelock to 3-5%.
[Nexus 4 Q&A, Help & Troubleshooting] TehVeggie:
I disabled all cell broadcasts for an hour.. went down from your 15 minutes to 12. My awake time decreased from around 40% normally to 29% now. It made a difference, but not the drastic difference like you had.

Edit: 30 minutes wakelock in 3 hours now.
[Nexus 4 Q&A, Help & Troubleshooting] pedxing:
Yeah I think you're right. I was previously getting an unusually high number of emails fr my exchange client during the original time I mentioned. It went down at the same time I turned off the cell broadcasts. So after several hours it's looking like 10% is a more accurate number than 5.

I disabled exchange syncs as well as Google now and it got even lower.

So basically anything that communicates seems to trigger it and the effect is cumulative. The more syncs you have the more the wakelock is. So instead of waking up quickly and syncing and then going back to sleep, it appears to continue to stay awake for an unreasonable amount of time.

Compared to 4.1.2 on my galaxy nexus, this blows. I'm used to an awake time of only 5% higher than my screen on time. On this device with 4.2 the best I can do (while still having the features that I'm used to) is 12 to 15% more awake time than screen on time. That's only by disabling latitude and location tracking and most notifications and syncs with g+ and the Google account.
[Nexus 4 Q&A, Help & Troubleshooting] dwang:
Yeah this is disappointing. I don't understand how Google didn't catch this during testing.
