OK ... thought I would try to set up standards so those that think they are getting poor battery life can compare. In case you didn't know you get a free movie with the nexus (I just found out myself). If you go into movies on the play store you will see "Transformers dark of the moon" is purchased ie free. So we all have an available starting point. I thought this would be the base for a test. For everyone else ... a free movie.

So I ran the movie over and over until it died. I got 5 hours and 25 min, till it died. I am running stock w/ 30 brightness. NFC and background locations turned off. Everything else turned on. I didn't want to use auto brightness as it creates an additional variable as it depends on your room brightness.

Anyone willing to take the test? Download the movie don't stream it as it will cause an additional variable.

Compared to my iPhone 4S with similar usage, the Nexus 4 drains about the same as a 1 year old iPhone 4S battery. Then again, it is needing to do more updates than the 4S, so I am fairly satisfied with the battery life.

Hi

Go to Settings - under Accounts click Google then click the first item at the top, then untick all items you do not wish to sync. The applications may still show as loaded and running, but they shouldn't be going on line and sync'ing any more.

About an hour of NFSMW and another thirty minutes of screen time with everything syncing in background, I'm down to 49% battery. I'd say its pretty good.

Auto brightness is on. I'm syncing Chrome, Drive, Gmail, Google photos, Google+ and Instant Upload. Still using the stock ROM and kernel, but I have rooted my N4.
[Nexus 4 General] Richieboy67:
Something I have not heard much is to go into your settings and into "running apps" .. This can show you what apps are putting a memory load on your phone.. This can at least help you figure out what to disable..

I use Titanium backup to disable. There is a sacrifice if you want really good battery life but by going in there and seeing what is running and by turning them off you can do pretty well.

I was surprised to see my new keyboard spp(swift key flow beta) using 64mbs of ram on a constant basis. I don't know what the CPU load is though.
[Nexus 4 General] undercover:
A lot. It is well heavy on battery, had to roll back to SwiftKey 3. But that's where you use it (actual process of swyping).

Re RAM. It won't be using that much power really. Let it just hang there.
[Nexus 4 General] eep2378:
Same here. I tried Swiftkey flow and that thing is HUGE. There surely is battery drain with it too. Honestly, the stock android keyboard gesture swiping works better. :D

I just got my N4 yesterday and I'm pretty impressed by the battery life so far. Just charged it for the first time to 100% yesterday and thats how it looks now (CM 10.1, franco kernel r14, a lot of whatsapp / facebook and fb messanger and some other things via wifi).

The New Facebook app does not battery drain at all
[Nexus 4 General] [hfm]:
I finally did a rundown to make sure I was still getting 4-5 hours. This is auto brightness, all location on, Wi-Fi when I can, Google now on, 1 gmail sync, 1 touchdown sync, etc... Also played quite a bit of spellwood and some Words with my wife as can be seen. also was listening to the hobbit soundtrack strangely that wasn't in the top battery guzzlers. So I wasn't babying it to try to stretch the battery time, screen on time had some good load.

Edit: ahh I see mediaserver did make it in there to put Google music in the top list. It was off screen not long before I took the shot.

The last 3-4 days I manage to squeeze 5+ hours on screen time from my battery life during the day. I am on franco latest kernels (r13, r14) and latest Cyanogenmod, wifi, auto brightness setting..

I can tell you now for sure that even if you use the same kernel different roms bring just different outcome on battery life. For example I am with PA now and I see not good battery life like in CM.

[Nexus 4 General] uEih:
I've been pretty happy with my battery life.. Usually goes a well 12-14 hours with constant email, texts, some games and the usual social media. I went from a phone with extended battery life which can last for 2 days before charge so it's not that great but tolerable.

I do wonder though if I keep it plugged in after its fully charged I'm not killing the battery am I? I don't see it saying "charging" when it's full so I wouldn't think it's killing my battery when it's full but I want to confirm this before I continue to leave it charged overnight.
[Nexus 4 General] cobyman7035:
i too wonder if its bad to 'overcharge'? just charge to 100% and take out?
[Nexus 4 General] DowntownJeffBrown:
Heavy usage and I think I'm standing OK not what I want but I'm getting there. I normally have my phone plugged in most of the day in my work truck as I'm in it all day so weekends are when I can wakeup and test my heavy usage periods.

[Nexus 4 General] @rbiter:
About an hour of YouTube, half an hour of music, a few short calls and 384/918 min/max CPU frequency, 384/810 screen off and auto brightness and about half an hour of broken sword. About 90% WiFi. Stock kernel on 4.2.1.

I voided my warranty.
[Nexus 4 General] [hfm]:
How is Wi-Fi using more battery than broken sword. That's ridiculous. Check out my post a few back where a ~ couple hours of spellwood is dominating my usage.
[Nexus 4 General] shotta35:
There is no such thing as overcharging a newer phone these days. All of them all have circuitry (phone and battery) that communicate when to stop charging. So even if the phone is plugged in for 2 weeks, the battery can tell the phone to stop sending current/amps till it's needed again (trickle charge).

Point is, other than your battery dying too fast, stop worrying about batteries these days as it's a non-issue. The phone with a smart OS and quad core CPUs and all that should be able to manage it just fine.

Some kernels may cause worse battery but I would suggest Franco's kernel for battery. I'm running Matr1x 3.0 and I'm getting even better battery than with Franco but a lot of people are having success with his kernel or francos But everyone's phone is different.

[Nexus 4 General] DowntownJeffBrown:
I'm gonna let someone else more technical explain the kernels to u more but I'll try to help. So check this out:

Think of the kernel as an interface layer between the hardware and software on your device. The kernel decides when things happen, such as the LED indicator gets lit. An application sends a request to the operating system to blink the LED. The operating system then sends the request to the kernel, which makes the light flash for the amount of time requested by the OS.

So basically by flashing a different kernel it can cause your smartphone to be more efficient by how your phone(the hardware) reacts to the software(your os or custom ROM). So Franco seems to have done a better job coding his kernel than the original. Hope this helps my brotha....

[Nexus 4 General] Ibsonic:
Thanks jeffery I know exactly what a kernel does.. Like hot plugging and finetuning ..etc, I was aiming more onto features ^^

[Nexus 4 General] Born_Immaculate88:
When I first got my Nexus 4 I used it without turning off anything but wifi for the first day and i got between 4-6 hours of battery life before it died from a full charge. Now that I have turned OFF wifi, GPS, NFC and set the screen brightness very low I'm getting between 14 and 16 hours of battery life each day with pretty heavy texting, youtube, streaming music (1-2 hours), several phone calls, GPS (only on when I used it) and 7 total accounts signed in to my phone (Twitter, Facebook, work email, personal email, Google account, GroupMe and Dropbox) all on push notifications and/or instant upload.

[Nexus 4 General] Lttlwing16:
I have found with all the tight Play services integration you HAVE to at least LAUNCH all the pre-installed Google applications (Currents, G+, Youtube, Play magazines, Music, Movies, Maps and Books) so the services can sign in. If not, they will eat system resources because of the Play services integration and their desire to sync.

After signing in you can turn off the sync in settings, but should probably leave them enabled, due to cross referencing in different apps.

Google should patch this in the setup wizard to walk you through all of the said apps. Its a major bug.

I would also disable Messenger and Hangouts in the G+ settings if your not using these.
[Nexus 4 General] drpepe:
Sorry but can you explain the reasons for this in a bit more detail? My addled brain can't quite get to grips with your post :confused::)
[Nexus 4 General] Lttlwing16:
The reasoning...on nexus devices pre-installed Google apps are system apps. These apps are trying to do their thing at start up, but the user hasn't allowed them to sync their data by not launching the app and allowing signing in with the Google account registered at initial set up . Thus they keep the system running. As I said, a major bug.

I noticed after having the same Android System/OS drain and trying to problem solve. I hadn't launched YouTube or play magazines since setting up the n4. After launching those apps, it signed in automatically and after, the problem went away.
[Nexus 4 General] kgeissler:
I think I found the cause of my battery drain.

It is called Ingress. That app will drain your battery so fast it will make your head spin.
[Nexus 4 General] hallucynogenyc:
This man right here might have solved the whole battery mistery. I had 0% deep sleep every day, and Google Services would usually appear as the battery drain cause. I just opened Google Movies and Google Books for the first time, selected my account and closed it. 10 mins later I have 8% deep sleep. Let's hope this stays!

Right. Me as well. I think it may have to do with USB hosting. Going to disable USB debugging and developer options and see if that is the culprit.

After my 2nd full day with the N4, I am a bit worried.

On a typical day, mostly on cell data, I have 2 hours screen time and 50% battery left with my GSM GNex.

That is with WiFi enabled, NFC disabled, Google Now enabled, location stuff disabled, Google sync only contacts and calendar, IMAP email every 15 minutes.

Now with the same apps/widgets/settings and same system settings, same screen time, same work location, I have only 25% battery left with my N4.

The N4 goes into deep sleep, but maybe only 80% of the unused time. For the GNex, it's much more.

The only thing I can see with BBS is that msm_hsic_host wakelock thing.

With the standard Android battery stats, I have high screen and 2nd place Android OS.

Yesterday, mostly on WiFi, I got 3 hours screen time. I think, the cell signal could be the problem. Maybe the N4 is not as efficient as the GNex there.

---------- Post added at 07:55 PM ---------- Previous post was at 07:33 PM ----------

Just did a quick GNex vs. N4 test with BBS.

Under wakelocks, the GNex does not have that msm_hsic_host AT ALL. And that is with the same OS version.

Someone posted on Google+, that this process has to do with the cell connection.

But, I was on WiFi while testing. And why does the GNex not have it?

So far I have to say, that the battery life is good enough for me.

Maybe this is the reason why our battery drains fast with stock kernel..

Our governor is not that efficient if you look at the CPU steps.. He skips the lower ones and uses 1000 right away... It's smooth as butter but a battery drainer. That's a fact.

I noticed, there is much battery drain when the device is awake but doing nothing. Such as screen on, but not working with it. Or connected via bluetooth to the car.

So, my current guess is, that it drains too much energy even at the lowest frequency (384 MHz).

This would also explain, why wakelocks have a huge effect on battery life, more than on the GNex for example, where I see no significant drain when connected to the car.
