[Nexus 4 Q&A, Help & Troubleshooting] Chuck4197:
I usually make sure to reboot at least once every couple days, im always good about keeping the system clean and all that stuff.

When i looked things up about the 4.2.1 Android OS drain earlier i ran into a lot of people that were having the same issue where the phone doesnt deep sleep and has hours and hours of " keep awake" time. I just wonder why mine decided to start doing it this week when i never had a problem before.

Im assuming we just need to wait till 4.2.2 gets pushed for bugs to get fixed, which hopefully is soon. Still, It would be nice to know what the problem is.
[Nexus 4 Q&A, Help & Troubleshooting] yokuyuki:
It's probably an app causing it then.
[Nexus 4 Q&A, Help & Troubleshooting] Chuck4197:
When i go to settings>apps>running apps, there is no app running that i didnt have installed while i was home. Does it not necessarily need to be "running" for it to keep the phone awake?

i was under the impression it was a problem with the system (bug or something) that was causing the Android OS keep awake, and not a third party app. Seeing as how so many other people are having the problem too, but im not sure.

The hsic wakelock fixes don't seem to make any difference in battery life. Here's a comparison I did of motley's kernel b21 and b22.

b21: no 3g hsic wakelock fixes

b22: with 3g hsic wakelocks fixes

On 3g, the biggest drain is the radio. And unfortunately, an update/fix can only come from google or lg.

Don't think battery use is a good measure since it varies from person to person and I don't fully drain my battery. I get about 4 hours screen time and 20 hours of battery life on wifi.
[Nexus 4 Q&A, Help & Troubleshooting] exygenysys:
Bump. But note to all: when I select "Use 2g networks only," I got literally zero battery loss overnight over 6 hours. Once I wake up and disable that option, the wakelock and battery drain comes back.

Anyone else try this?

Edit: if, as someone suggested, this is caused by communication between the SOC and the radio, then maybe the complete lack of battery drain on EDGE/2G only is because that route isn't required for it? I'm just speculating.

Been on 2G only for the past hour, zero drain. Someone else should check and confirm; not a solution but will help with overnight drain at least.
[Nexus 4 Q&A, Help & Troubleshooting] crazygameofpoker:
The "college problem" is widespread. The WiFi Optimization option helped me greatly, but before that if I was on my university WiFi network Android OS would drain the battery. What is happening is that the device is constantly sending and receiving data via the WiFi network. If you take a look at your WiFi logo in the notification bar you will notice that the down arrow is almost always on. It's keeping the device awake.

I have no clue why this is and I'm sure it's not limited to university WiFi networks but rather networks with multiple routers (I don't know much about this stuff; these are educated guesses). But you are not the only one.

[Nexus 4 Q&A, Help & Troubleshooting] dcdttu:
I've been waiting for someone that uses LTE in Canada to chime in on this. So you're saying that on LTE the phone has better battery life than on 3G?

No phone ever should do that, unless something is wrong. Also, this is why the Optimus G, with identical hardware, gets so much better battery life - it is probably on LTE for most of the online tests where they post those amazing 20+ hours of battery life.
[Nexus 4 Q&A, Help & Troubleshooting] kaiser_tytnii:
Well, that's not 100% true because LAC is unknown so location reporting is not active; thus, leaving this an apple-orange comparison

[Nexus 4 Q&A, Help & Troubleshooting] sona911:
Not solved

4.2.2 Here with the new base band and guess what? Not yet solved. This is a hardware issue maybe. And yeah, NFC is disabled. 23% battery lost for an "idle" phone for 3 hours is a pure fail obviously.
[Nexus 4 Q&A, Help & Troubleshooting] nyijedi:
Yup, not fixed. It drained 7% of my battery while idling over night without WiFi on (in an area with great cell reception). Really starting to be disappointed with Google.
[Nexus 4 Q&A, Help & Troubleshooting] yokuyuki:
Is that how much you were getting before 4.2.2? It's not going to go away, but the fix should be a reduction.
[Nexus 4 Q&A, Help & Troubleshooting] nyijedi:
Unfortunately, that's about what I was seeing before 4.2.2. Before the update, I'd see anywhere between about that and 12% when idling overnight. I'll check it a few more times, but it seems to be in line with what I was seeing. It's a shame - when on the same cellular network, my Galaxy Nexus only drops about 1-2% overnight when idling. This phone drops about 10%. Obviously I have the same configuration on both phones, otherwise I wouldn't be comparing them.
[Nexus 4 Q&A, Help & Troubleshooting] yokuyuki:
Haven't gotten around to idling it overnight as I just updated, but in the last 40 min, it's at 3% of kernel wakelocks in BBS which is a huge improvement to the 15% I normally get on 4.2.1 and Franco kernel.

Not sure how people are getting their update whether by OTA or adb but I did an adb sideload of 4.2.2 to an unrooted stock 4.2.1 N4 and have seen great improvements in wakelock times and battery. Used to have around 40 minutes by midday. I have 3G, WIFI, GPS, and NFC enabled if that matters.
[Nexus 4 Q&A, Help & Troubleshooting] dcdttu:
Updated my N4 to 4.2.2 and it fixed several issues, most importantly it seems to have really, really improved the battery life. I used to be at 75% or less by noon on a typical work day. Today, which was typical, I was holding strong above 90%.

Hooray! I always heard about Droid DNA's and Optimus G's going up to 20 hours with ease, and wondered how they could possibly do that with the same chipset. With the 3G wakelock or whatever was wrong with it, they seemed to have fixed the issue.

Also, I can connect to my work's wifi, which I've never been able to before. I'm sure that helps with battery life too.

Completely stock Nexus 4, update to 4.2.2 didn't fix anything, msim_hsic_host wakelock is at 1 hour with total time since unplugged is 4h as of now. Exactly what I was seeing before the update.

I can't quite get through the day without charging around 6pm when I get home, I'm usually at 10% by then.

Yep, that is stock, though on wifi. I turned wifi off this morning to test and since then, on hspa, the wakelock time has gone up by roughly 20 mins over 9 hours. A bit more than on wifi, but that makes sense since as I u der stand this wakelock is related to background network traffic, and obviously on a slower, higher latency connection, the phone is going to spend more time awake. I don't think 4% of time wakelocked for this is a problem really.

I used to get high figures like that on the stock 4.2.2 I believe the wakelock bug is only on 3G, WiFi and 2G seem to be OK, so it will depend on you usage patterns.

2. ROM of March 18 - Battery Drain in Deepsleep Mode 2-5% per hour

My device suffers from high battery drain since a few weeks now. I am currently on AOKP build 6, tested a few different kernels with no real success.

I bought BetterBatteryStats to have a deeper look too, but I have no clue what to do with the app's outputs... At kernel wakelocks there is almost everytime the msm_hsic_host on top, partial wakelocks leaded by PhoneApp and RILJ, Alarms com.android.phone,...

[Nexus 4 Q&A, Help & Troubleshooting] motoridersd:
I get the msim_hsic_host wakelock often and I don't know what it is that is causing it to keep my phone awake so much.

It must be an app, since my battery life has not changed. It's the same with 4.2.2 stock as it was with 4.2.1. I'm running PAC 22.1.0 and Franco r122.

Here are my BBS screen shots. My deep sleep is MUCH better with the latest PAC Rom and Franco, with versions from last week my deep sleep time was lower.

I've turned off background sync, google location, latitude, and turned them back on without much change. Right now Latitude is off, and everything else is on. I have 3 gmail accounts, 1 ActiveSync exchange account, Instagram, Twitter, Facebook and MightyText. These are the apps that will do the most push notifications and traffic in the background. I thought MightyText was the cuprit, but removing it didn't make much difference.

The only thing I have not tried is running my phone without ANY of these apps, but if I do that, what's the point of having a smartphone? :P
