Which ROM performs the best in terms of battery performance. If you are using any Governor and I/O setting please do mention them.
PA rom...Franco kernel...ondemand settings...
I'm also curious on what you guys experienced.
I'm currently testing Franco R15 with Stock JB on my Nexus 4. It's the first day and I'm running for 9 hours with 1h 46M of screen time.
So I'm expecting about 3h 30m of screen time.
Will give it a fews days and report back. Then I'll try out Matr1x.
Please use search next time because there are threads with the same exact title. No such thing as a best kernel. It is subjective such as if you were to ask the question, what is the best car for conserving gas usage.

My first cycle (settings on signature) gave me almost 4hs of screen time.
Trying second cycle today.

your sig is wrong, unless you are running 4.1.2?

I'm going to give francos kernel a run to see if I can squeeze a little more out the battery

I'm on Stock rooted using Franco's R15 kernel since a couple of days. Every charge cycle brings a slight improvement. Will test the kernel for a week and then flash Matrix's kernel and compare.
Thanks for letting us know.

So ~5 hours screen time. And you got 1.4 days on WiFi with hardly any awake time. That's not really a good measure of battery life.
I don't know about everyone else, but I find the Nexus 4 gets really good battery life. Maybe not as good as the GSIII or the H1X+, but those have tremendously aggressive power-saving features.
Using faux kernel with Snake Charmer (caps max freq on all 4 cores) and Eco Mode (only allows 2 cores to be simultaneously active) provides adequate performance with very good battery life; even better if you undervolt. You will definitely beat the GS3 or H1X+ with those faux kernel settings. I don't use Eco Mode, because my phone lasts nearly a day, and I can charge it mid-day. I should probably be more conservative so I won't have to replace the battery as soon, buttphuckit, I do what I want.
I've used faux, Franco, motley, and Matr1x a lot. As of now, the best battery with performance goes to Matr1x by Mathkid. Version 2.5 undervolts by 150, which my phone runs fine. However, a few people had instability because it was too low for their devices. Enter v3.0, which undervolts by 100 (and you can uv even more using System Tuner or perhaps Faux app). Either way, great battery life (I routinely get 5 hours screen time with 16 hours battery time, or 4 hours screen with 24 hours total, etc).
Absolute best battery life is probably faux with his battery optimized settings (1.35 max speed, snake charmer, eco mode, and some undervolt by 100 or so). It runs fairly well, but it's not as quick and smooth as stock because it sacrifices some of that for battery (fair trade off if you need it because it's still a damn fast phone). People have gotten 6 and even 7 hours screen time. Obviously this won't happen playing games but it's possible with light browsing and texting and whatnot.
Motley's kernel also gets good battery and excellent performance. Franco's kernel does too, but not quite as good of battery because it doesn't support undervolting YET. When it does, it might be the best battery for performance of all (likely).
I use Matr1x daily and am happy with it. Some people, even smart devs, will sometimes tell you undervolt battery gain is negligible. However, at least with this device, it can make a huge difference because it handles such a big undervolt while remaining stable. It also stays much cooler and will run at high clocks longer before reaching the thermal throttling limit.
Anyway, some people might disagree, but these are my experiences. Franco has a huge following and for good reasons. His kernels are awesome. I just don't think the battery life will compete until he adds undervolting. He has said this will come when he feels it is stable and good overall. I'll probably switch then unless Mathkid adds more features to his like gamma control, etc.
Hope this is helpful. Btw, another thing I really like about Matr1x kernel is that he uses the older touchscreen driver which increases screen sensitivity. Many people complain about the nexus 4 screen sensitivity, and if that applies to you, this will fix that.

^^ A good write up, deserved its thanks. Am on latest rasbean & matr1x, never experienced smoothness & battery life like this. Screenshots at the Matr1x thread later today.
However, all users are different. Battery life WILL differ, that's the only certain thing.

I dont care much about customization. I just want great perfomance and good battery life. It is really hard to choose a rom because all of them feel almost the same? Thanks
I use rasbeanjelly with trinity kernel currently at 71% with nine hours on and two hours fourteen minutes of screen time I've gotten two days with five hours screen time before and still had about 25% battery left. That's with wifi on off while tablet is asleep, location services on, and two email accounts on sync. I got some slightly better time on Franco's kernel but I had to disable location services to stop SoDs I read that a voltage bump might fix that. Making it worth another look. As always try around and see what works for you not all of these tablets are created equal.

...Who seems to be getting worse battery life since I've rooted and installed CM10 and Franco Kernel than stock.
Before with stock I was only losing about 1% every two hours on standby (sometimes even better I've no idea how)
Now I'm losing about 3% an hour on standby and also about 30% an hour screen time with just basic browsing (Screen brightness set to auto).
Also Media server is hammering my battery. Like I lost 3% battery in 15 mins without the screen on just playing music (not streaming) is that normal, I've come from an iphone 4s which didn't lose that in an hour :S
have i flashed it badly is there something else maybe i should try or are these stats about right ????
thanks guys
That's just the way it is just custom roms. When flashing, put your head between your legs and pray for the best. You can spend hours trying to figure out what's gone wrong, but you might never get an answer.
You can try underclocking your N4. Currently my dual-core Snapdragon S3 T-Mo Galaxy S2 is underclocked to 810MHz from 1.5GHz and performance is still great. I'm guessing you can UC your N4 to at least 1.2-1GHz and performance will still be great because of the quad-core Snapdragon S4 Pro CPU. Also, what governor and i/o are you using?

Hi Gents
Thanks for the reply, yeah it does seem a bit of a hit and miss kinda situation, I'm not masively bothered, im hoping eventually someone will stumple across a fix for the way the screen murders the battery life but im not holding my breath. Still love the phone, really getting used to it now, have tried (and failed) many times to switch to android, must be honest, this is the closest I've come so far to waving bye bye to ios, android is really really fantastic as an os, it's also super pretty to look at these days, stock apps like contacts, calender and the phone app itself are beautiful.
Let the phone and battery have several cycles, it will improve, eventually
thanks mate !!

Under clocking your phone isn't a viable situation. It's a phone, what's the point in it if you're not going to use it to your fullest when my phone lasts through the whole day going from 384-1500?
Some battery tips for op:
- download better battery stats (Google it for a xda version) use this to debug wakelock and ensure your phone is deep sleeping under cpu states. You can also use cpu spy to check cpu stats. Better battery stats is a must need.
- disable Google latitude in maps. Disable the automatic reporting and any other checked marks
- disable Google now cards that you have no use for
- disable gps (some apps use gps and drains battery when it keeps using gps when it isn't necessary)
- ensure your governor is interactive and on latest version of Franco (r20 is very good)

Just stick with the stock kernel that comes with cm10.

Highly advise doing that. Other kernels are way more optimized whereas CM is focused on the ROM itself and not optimizing the stock kernel.
I believe CM10 uses stock Google kernel anyways (could be wrong).
Use Franco Kernel or anybody elses kernel that you choose to.
Mine definitely improved after rooting and flashing custom ROM. Battery life when I was still stock was horrible.

A ROM has very minimal battery life improvements, it isn't as significant as a kernel. Hence the definition of "better"
i don't care about gpu or overclocking my device.. all i want is to unplugged the n4 form charger and go working in the morning and at night before bad to put it back in the charger - without it dieing on my before..
i had htc sensation and it last all day for me, i'm now 2 days with the nexus 4 , and after 12 hours the battery is dead.
i'm currently using Cyanogenmod 10.1 18/2/13 nightly . turn off locations, and Facebook sync. using only automatic brightness (witch my the way is very low), WiFi and gps and Bluetooth always off . 3g on.
thank you!
Usage varies across any ROM/kernel combo. No one can really say what's best, because everyone's usage varies. But, I can and will say, I'm having best battery life so far using asylum nightlies with matr1x 7.0 kernel. I have a very strict setup which I'm not getting into, but I am in no way limiting the function of this powerhouse. If that makes any sense. Currently sitting at 63% with almost 3 hours screen time. 50/50 3g/wifi and heavy use. think streaming, gaming, downloads. It would take me a very long time to describe what I do to get this battery life, but I would be willing to explain if needed.

I recommend AOKP build mr3, and Harsh's kernel. No need to tweak anything, everything is done for you and you get great battery life. Just my experience from it.

I'm using paranoidandriod with Franco kernel. I get great battery life all the time every time. Download the kernel and leave the settings as is and let it do it's thing.
Note: This has been asked too many times. You can search up the old ones and you'll pretty much get the same answers that it all depends on what you do. Battery life is subjective. It depends on the user. If someone only uses their phone for calls and text they will get awesome battery life. If another person has the same setup as the first they did play lots of game and play videos and such, battery life would not be so great. Thus, both users will tell you different answers.
Just try them out and see for yourself.

Anyone got any good r65 kernel settings for battery optimized? I love the Franco Kernel but my battery life is lacking. Especially when its in standby mode with the cover closed.
BTW, Im running PA 3.65 and downloading 3.67 as I type this..
The default settings are actually about as good as it gets, short of underclocking. You might consider trying another ROM to see if your battery problem improves at all. I liked PA a lot, but even without HALO my battery life was terrible.

Use better battery stats to see what is keeping your device awake, it should use very little power in sleep.
May try using one of many apps that can turn off wifi in sleep and check out greenify.
This may not be exactly what you want to hear, but I switched over to Aospal, a linaro version of PA. I have had significantly better performance and battery, both of which vanilla pa failed to deliver. I also am using m kernel, and I lowered the CPU frequency cap to 1200 MHz. I am using otherwise its default settings. My battery life is more than doubled from when I was using vanilla pa. So if you are interested in switching, (it still has everything from pa!) this is working for me.

Currently using r65 and coudnt complain about the battery.
While checking out roms, you could also look at apps you install. Some very poorly coded apps (especially facebook) would just eat up your battery, and use a lot of memory.
Hello.
I'm looking for a kernel for the Nexus 4 of course with the best battery life.
I almost don't play games, I just need a kernel with gamma control, sound control, and one that would not cause stutter to the device with battery life.
I used Franco r203 and I had only 1:30hr screen time, now I'm trying Franco r203 Plus but it cause stutter and pretty much the same battery.
Any suggestions?
Thanks!
I'm currently using hells-Core and have 2 hours of screen-on with 40% battery left.
(Maybe there are better battery-friendly kernels out there, but HC performs pretty well.)
I enjoy Faux Kernel and undervolt 50 and under clock to 1.2 I can make it through a day no worries but this will depend in your usage as well. I do probably medium of everything such as social networking, internet browsing, emails and some games. I usually end the day with above 20%

As you would have already known by know battery usage depends upon ROM build and apps and your usage patterns. To extend the battery a bit more you can Hellscore,Matr1x,Piasek kernels...they gave the best battery life for me. Try and let know

Both are best but Matr1x retains smoothness for me as compared to hellscore.Flash both and test for yourself
