You should try PA if you haven't just so you can do your own personal tests. I suggest giving it three days before you begin seeing consistent results. Last thing, kernels are critical with battery life. More important than roms I believe. Correct me if I am wrong.
[Nexus 4 General] saniyal:
I have tried using PA for a week but I get worse battery life like around a hour with cm10.1 I get around 3 hours.
[Nexus 4 General] Zainiak:
try matr1x or franco kernel.
[Nexus 4 General] mcvigo:
I did man! Got the worst battery life ever with it and franco 116. I got pissed so I flashed stock images and now running 100% everything, right now im @ 2:40 SOT with 13 hours standby, with 39% left. Gonna discharge it to give it a full cycle.

---------- Post added at 07:26 PM ---------- Previous post was at 07:24 PM ----------

I really want to use PA cause it rocks, but battery life is too important.

I was getting good battery life with stock and franco and i started flashing different roms and kernels, starting by cm10.1 and battery got progressively worse.

Gonna use clockwork instead of touchwin recovery next time I flash, also what should I wipe, data, davlik, cache and system?
[Nexus 4 General] saniyal:
Yeah I took your advice and went to faux kernel I got 1 hour screen on time whit 15% thanks for your advice
[Nexus 4 General] ran495:
wait, so its really true no custom kernel can defeat stock in terms of 3g on all day??
[Nexus 4 General] razball:
Yea I rarely see 4 hr sot cause I'm 95% on data and no WiFi. And that's on any ROM and kernel average is 3 hrs sot by about 10% but that's also over 15-18 hrs of use too.

I got great battery with PA and franco kernel (r111) and BatteryGuru
[Nexus 4 General] clusterchuck:
It depends on what you mean by data all the time. The screen times I posted were from me in my home for most of the day where my signal constantly changes from h/3g to 2g, depending on where I'm at in the house, with wifi on and doing nothing on it but playing games, texting, and about 20 minutes of browsing. Lasted almost 5 hours.
[Nexus 4 General] bagou01:
have you guys at least tried with stock kernel ? i mean, i get 2.5 days easy on stok and normal use :-/
[Nexus 4 General] Tom540:
I usually get 4/5 hours screen on for about 14 hours on battery using CM 10.1 and Franco kernel which I think is pretty good

[Nexus 4 General] cupid412:
Have anyone ever experienced battery dropping like this?
[Nexus 4 General] saranyan:
Guess the phone had a random reboot. Did you uv the kernel voltages?
[Nexus 4 General] cupid412:
I restarted the phone myself. Btw, I have trickster mod but I leave its default value, didn't change anything.

I just tested 2 times again and the same thing happened.

Fully charged + reboot = 6-8% battery drop. (Less than 92-93% battery + reboot = normal)

I'm using PA rom + faux's kernel + PowerQi T-100 wireless charging.

Will post the results with another kernels.
[Nexus 4 General] jarjar124:
Was happening to me as well. A reboot during charge fixed it for me.
[Nexus 4 General] Fwosh:
15 minutes of Netflix streaming on hspa saw a 24% drop...
[Nexus 4 General] walkingmike:
Yes I just did yesterday. 4 Hours SOT with 3G all the time, still had ~15% battery left, normal usage, gmail, Whatsapp, Phone, some browsing.

The other 15% I turned on screen wakelock to see how far I could get with the SOT and scored 5++ hours. Keep in mind this 15 mins is just for testing, Airplane mode on and I just left the phone untouched.

Stock Rom, Franco r111, Undervolt by 100mV, Juice Defender and Greenify. Auto Brightness.

I'm undervolted 125mV with Franco's kernel on Paranoid Android. On average I can get 30 hours with 3 hours SOT. On days with heavier use I get around 16 hours and 4 - 5 hours SOT. I'm more than satisfied with my battery life.

My Nexus 4 is running stock android no root.

I never turn off my Wi-Fi or 3G. I used the phone all day texting and calling. My brightness is set to auto and vibrate only. I however did not play any type of game on my phone. Did some light browsing and Facebook and twitter other than that bit was mostly texting. This is what I got out of my battery. :)
[Nexus 4 General] Techguy18:
It is better to run all 4 cores (than only 2) at limited clocks.. eg:- set the max clock of each core to 1.2 Ghz.. because 2 cores will have to run at higher frequencies and consume more power..
[Nexus 4 General] walkingmike:
4 hours SOT again with spare battery left. This time I'm trying -150mV across the frequencies. Guys at the Undervolting thread suggests it's still pretty stable.

[Nexus 4 General] nextelbuddy:
people that have great results like this i have a questions..

how do you have your SYNCING setup? do you have AL syncing disabled so that the device only syncs aps when YOU want it too?

when i used battery GURU from snapdragon it literally disabled ALL my google syncing and when that happened I could get results close to that but with my normal syncing of browser, chrome, gmail, people, drive, sond search enabled then i cant really get very great battery life such as 16 hours with 2 hours screen time

Bought this phone on Wednesday.

I have unlocked and root, but stock recovery and rom on Thursday.

Until yesterday, the battery was lasting much less than the pics a I am uploading right now.

I don't know why.

The only different thing that I did yesterday was getting the nexus charging more then than the necessary..

I hope it keep this way. For me is enough.

All day long wifi connected, whatsapp and tapatalk a lot and reading gmail.

No nfc, Bluetooth, and GPS.

Syncing Gmail and dropbox.

[Nexus 4 General] simonali68:
I gotta say that, coming from a DHD, I'm more than happy with the battery life! I use my phone as a wifi hotspot for a tablet at work and had to leave the htc plugged in the mains all the time, as the battery would last around 1 hour whilst tethered. The N4 will last nearly an entire 12hr shift running on the battery alone and I just plug the charger in for the last hour of my shift to top it back up...
[Nexus 4 General] Ollie_17:
I normally get about 3 hours screen on time with browsing on internet on wi-fi and a few other things. With gaming just under 3hours
[Nexus 4 General] marshalex:
After 2 hours on battery, 50 mins of music streaming over bluetooth, wifi on, gps on and screen time of 6 mins down to 84%. Vanilla music rinsed my battery this morning much more than winamp usually does. looks like its time to find another music app. As long as battery lasts until the end of the day can't say I'm overly bothered but would have expected it to be a bit better than it is
[Nexus 4 General] Desvbo:
Sorry for causing confusion, these are not from the Nexus 4. These stats will only be possible with custom kernels / undervolting / modding ...
[Nexus 4 General] Stretlow:
Not sure whether its been mentioned in previous pages but one of the Main Kernel dudes Franco is now on the N4.

He's hasnt got the device at the moment but has still got a couple of versions, a kind sole from the forum has agreed to lend him an N4.

I rooted, flashed a custom rom and his kernel (there is another version since last night)

Had no issues, will report later

If you're serious about getting some extra juice (and performance) this is the way to go.

1st day, not too bad I'd say. Anyone else having high wake locks from the Phone app?
[Nexus 4 General] funkyblue04:
I do not understand WHY battery life is not the Number 1 focus now. Who cares about higher specs when you cannot get a day of high usage out of a smartphone?
[Nexus 4 General] marshalex:
I think the problem has to be in the kernel somewhere as it seems that the google background services are using a lot of CPU usage (maps being a key one and the media server, OS etc). With the other minor issues floating about hopefully an update will be out soon
[Nexus 4 General] Richieboy67:
How often are you really away from a charger?

They could make the phone an inch thick for you or they can have it light and thin and you either turn off all your running crap or you charge often...

If you turn off the maps and the auto syncs, keep your screen brightnes low, and avoid heavy, have usage meaning video, games, etc then a day is not an issue for most.

[Nexus 4 General] aubzaubz:
Can I ask what you had enabled / disabled? Eg. Auto sync, wireless, google now, GPS etc.

At the moment for me during idle periods i'm only seeing 85% deep sleep and about 15% at 384mhz. And that's with auto sync, google now, wifi, gps turned on.

Can someone comment whether 15% of the idle time at 384 mhz is irregular or not?
[Nexus 4 General] eep2378:
That makes sense. I had mostly everything off(auto sync, gps, wifi, google now). I just got the device last night, I havent even put my sim in it yet. If you have location settings enabled with location history and latitude enabled in maps then you'll see idle drain from those apps. That may be what your seeing. Try turning some stuff off and let it sit for a bit and see what kind of sleep % you get. That way you can have a reference point. :)
[Nexus 4 General] yfbc:
Mine seems to drain pretty quick whatever I do, wifi seems to help and switching to 2g when not using the Internet helps.

[Nexus 4 General] ceejay83:
The screen is a battery hog, while the idle time is great. I drained 1% over 5 hours on Wi-Fi with sync and gps on
[Nexus 4 General] mobilehavoc:
I will +1 this...this phone idles like nothing else I've seen. I think more than the screen burning battery I think Chrome kills battery a fair bit too. I switched to Firefox beta (get Flash that way too) and it seems a bit better than Chrome.
[Nexus 4 General] nyijedi:
I noticed my battery drop about 2% per hour for a total of 10% over 5 hours while idling on my first night with the phone. This was before I let the battery full drain and die. Is it reasonable to believe that not having yet calibrated the battery contributed to this? I had google services syncing via Wi-Fi, and that was pretty much it.

ALSO, do people think that setting WiFi to never sleep when home gives better battery life than letting it sleep, since when it sleeps, the phone switches to the mobile network? I'm talking about situations where there's strong, consistent WiFi - not just leaving WiFi on all the time in general.
[Nexus 4 General] Basil3:
Is the idle time legitimate, or is it like the one x where you only get 1% drain over a few hours, then it magically drops a few percent when you start using it?
[Nexus 4 General] ceejay83:
It was your first day with the phone, you need to let the battery settle for a few days. Wi-Fi drains less than 3g/hspa, except 2g
[Nexus 4 General] radeon962:
If Chrome on the N4 is the same as on other phones, turn off "Enable Tilt Scrolling" in Settings>Developer Tools> Uncheck Enable Tilt Scrolling. Need to close Chrome then and some people have re-booted the phone. Helped me with Chrome on my S3.
[Nexus 4 General] alpha beta gaga:
that improves battery drain?
[Nexus 4 General] DrunkFuX666:
OK I have 2 questions... Read different things in different places... Let's see what answers I get here...

1. What uses more power, using WiFi or using data...? I'm aware that the faster your data connection is apparently it uses more power, but unfortunately I only have a Edge connection (2.5g)... So what's more a hog... Edge or WiFi...??

2. I've read different places something about using a SLEEP button to turn off the screen or Lock the phone... This can be found in the shortcuts you can add to your notification shortcuts for those who arnt sure about what I'm talking about... (These are usually in custom roms, not stock)...

Question is, is this any different from just locking your screen with the normal power button, or is there really some basis behind this "sleep" button...??

[Nexus 4 General] davidsteele1975:
WiFi should use less power when using it to download. It (should) download the file quicker so the radio spends more time at idle.

When connected but otherwise idle, I suspect the practical difference is indeterminate, especially if you disable 3G. One may be more efficient than the other, but I suspect the difference is probably only a few minutes of screen on time if that - going on my evidence.

If anything, I've found modern GPRS / EDGE radios to be less efficient than 3G when
[Nexus 4 General] Ace42:
1. Data(assuming it's HSPA/LTE/etc). Due to the slowness of 2G I fear it'll use for power by spending more time downloading something that wifi could do quicker. Also depends on signal strength
[Nexus 4 General] user822:
Mine gets me through the average day quite well.

I usually have at least 40% battery left at the end of the workday.

On weekends when I use it more it needs a fresh charge in the early evening.

Most of the people with smartphones complain a lot more.
[Nexus 4 General] Karlo666:
Or make Tasker action to turn off mobile data when you are connected to WiFi.

The only thing that stinks about turning off mobile data completely is that you don't receive MMS... So I usually just force 2G.

i've only had the device for a few days so wasnt sure what to expect but i'm assuming the rom/kernel I am using has helped a lot. (revolt/franco)

I think my drain is my high 3G usage. It just drains faster when I'm using data, like streaming music, and the phone sometimes warms up. I used about 10 GB per month.

Those with good battery life, how much data do you use a month?
[Nexus 4 General] saniyal:
I use around 3 and a half GB but my screen isn't on most of the time because it is off streaming music or whatsapp
[Nexus 4 General] razball:
It might be the data usage because when in just read some sites and go on pulse and hardly use data my sot is almost double what it normally is.

I use about 15gb a month and get an average of 2 and a half on screen over 15-18 hours

That's about what I used to get! I installed PACman ROM, franco Milestone 1, undervolted by 100 mv, and installed Juice Defender with data off while screen off except during Spotify streaming, and wake up every 30 minutes. It's also managing my wifi.

My battery life improved a lot:

But I still have something keeping my phone awake for a long time. Better Battery Stats showed me the offending wake lock, but I had to reboot and after I did I lost the data.

The only downside to this is that Mighty Text does not work instantly and I also missed an MMS. It never downloaded properly because data was off.

I still was unable to get through a whole day of usage, and my Spotify streaming was much shorter today since I listened to a podcast on the drive to work this morning instead of my music.

I'll take any improvement though. My best screen time was around 1 hour before.
