First of all, I want to thanks every developer whom make ours Evos looks like a new phone.
I have been using mikg since I rooted my 2 Evos. I tried cm7 and I went back to mikg because the sence. I used cm9 for 2 days and is so amazing. I do like it way more, even without 4g. It is so smooth, just the best ROM I ever tried. But, there is always a but, since cm9 is an AOSP I expect better battery life. In 2 hrs went from 95% to 15%. Today in the morning went from 100% to 75% in half Hour. So I had to went back to mikg cuz I have more than 24 hrs w/o charging. I tried to find some trick or any scrip or something to get better battery life but I did not find anything.
Please I will really appreciate any help on this.
Thanks!!!

Have you tried to flash the Mason SBC kernel with it? I think the cm9 port has a mason kernel baked in but it doesn't have SBC. I've been running the Mason I .15rc3 kernel with it and battery life has been great. Also, give the rom+kernel a few days to settle in before passing judgement on battery life. I've found that after giving a fresh install of a rom/kernel a few days the battery life will improve.

Yea try it out and let us know. Just remember, with SBC kernels, you want to let the phone charge for about another hour or so after it reports that it is fully charged in order to get the full SBC effect.

I get your advise and I have to tell you that I notice the difference in just 10 mins. Now we are talking about. I was off today so I decide to play with my Evo to test this kernel, I spend almost 5 hrs(straight) between playing with settings, browsing the internet, setting some apps and watching videos from the internet(2 hrs maybe) and I'm on 20% right now. I think that's pretty good. Thank you for the advice!!!
I don't know about u guys but on my evo using stock battery which is 1500mah will last more then 24hrs using cm9.

I have the 1500 mah stock batery too and with cm9-stock kernel I had a poor bat-life, Yesterday I flash the Mason I .15rc3 kernel and so far I'm impressed.
My set up is;
Evo 003 stock battery
cm9 nighties 05/10
Mason I .15rc3 kernel, Wheatley governor (min cpu 245mhz - max cpu 1075mhz)

CM9 comes with a MANSON kernel, but in not the same one. The one that I flashed is the "I 15r3", means that is the 3rd released candidate so is not a final version yet. I'm not sure whats the one that comes with cm9, but I think is a basic version of Manson Kernel made for cm9.
Remember this are electronic devices, maybe whats works for me don't work for you and vice versa. This is a great example. The cm9 stock kernel works great for you, I didn't get the same as you, but I get it with another kernel.

Well curiously I get lost Today when I was driving and I was scared cuz I haven't tested before and it worked great for me. I used it with a voice command and responded very quick and very well.
I think that's pretty cool.
So my N7 arrived two days ago, and I immediately unlocked, rooted, and flashed some things. Currently running Codename Android with Trinity Kernel.
My battery is absolute crap now though. Its been two days so I thought the battery more but have settled by now. All auto sync off, brightness at lowest setting, apps sync every 4 hours, still bad! Does calibrating still work? I read somewhere that it was debunked and it didn't work. I would appreciate any help. I mean, my Maxx is getting better battery life.
I uploaded some screenshots of the battery after only 1 and a half hours.

Go to the motley kernel thread in Original Development. He provides a mirror link for the stock kernel
I loved Trinity and the TKT app but for some reason im getting much better battery life with motley kernel. I originally did some troubleshooting and fixed some apps that were causing wakelocks. My battery life got a little better but not by enough (could only get 3 or 4 hrs screen on) so i switched kernels.
If you feel like experimenting do this:
Nandroid
Wipe Cache + Dalvik
Wipe System
Factory Reset
Flash CM10 nightly (any rom of your choice)
Flash GApps
Flash motley kernel (i used the 484 GPU version)
Fix permissions
Reboot
I get awesome battery life now and performance is great.
Your title should be something like this: "After rooting and installing battery draining rom and kernel I get bad battery life on my N7"
Stock JB and kernel should yield decent batter life.
With the proper rom and kernel the Nexus 7 easily match or better the googles battery life claim.
FYI the latest Trinity kernel is a battery hog.

I wouldnt go as far as saying its a battery hog, but i ran the kernel at stock clocks and while performance was much better than stock i still had tons of drain that i now dont have with a different kernel.
Ran Trinity kernel at 1150mhz and had awful battery. Back on stock ROM and kernel and seems to have improved a lot.

I feel like the battery is pretty decent...
Get off those custom Roms and kernels until you understand how the device is meant to perform.
You appear to have 87% after 1.5 hours, that equals about 10 hours, how is that bad? I get about 8 hours if I am intensely playing with screens, apps and games, 2 days if I'm not doing much. Loses 2% at night with wifi off. No root.
trinity kernel and the pure aosp rom, at 1150mhz. id say not bad at all..
Trinity Kernel is a good kernel. I went overboard by saying it was a battery hog. I did have it overclocked up to 1500hz on-demand and it ate up battery faster then I would like. But this is with the newest one, a few of the older ones worked out better for me though.

I have some problems with *wakelock*
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.

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.
Hi Im an user from nexus 4 since 2 months ago .
since the first day i rooted and change my rom.
i used to use cyanogenmod 10.1 RC2 + Franco Kernel M2 or 134 these days.
when i updated the franco kernel my battery began to drain too much even when the phone was idle. so my battery died in less than 10 h!!!
so i come back with CM kernel and right now my battery is during like 1 day!
im thinking in use rasbean + trinity kernel but i dont know if i should to use faux, semaphore or other one.
i just want my phone to use social apps,calls and i wanna take care of my battery.
what do you recommend me?
Thank You!
Use whatever you like. Find what's best for you.

You won't get a proper answer to this because the question is completely subjective and experiences vary from user to user. It's the same as asking someone what the best colour is, there simply isn't any correct answer. I'm sure if 10 different people replied you'd receive at least 4 different suggestions.
I too was trying to only get the best battery solution for a couple of months. I ended up using PA with stock PA kernel because the performance was much more efficient, with improved battery life over stock.
okay thanks guys!
In all honesty I used to drive myself crazy with this question, then I realized that there are simply to many variables that are constantly changing from day to day. Now a days I just rock out and charge when I need too.....call me weird lol

So I got a Nexus 4 last week, and I couldn't be happier. Coming from the Galaxy Nexus, this phone is essentially everything I loved about the Samsung, but on steroids. I was a HUGE crack-flasher with my Samsung, but the fluidity of the stock Nexus 4 is impeccable. Which brings me to my question --
I'm getting around 3.5 hours screen on time if only on HSPA+, and 4.5 hours if on mostly WiFi. Would the battery life be improved significantly if I flashed, say, Franco's Milestone-2? Or is it generally not a big difference if you flash a custom kernel on a stock ROM?

It depends on your usage. Personally I get the same amount of screen time on a custom ROM or on stock ROM with Franco.kernel. You also have to manage your apps according as well and having a good signal is an important to a longer battery life as well. Doing light tasks will increase screen time as well. Gaming will deplete the battery by a lot. So it really just depends on your usage.

I appreciate the response. Question for you: does fluidity remain just as beautifully magnificent if using Franco's?
Sent from my Nexus 4 using Tapatalk 4 Beta
stock with franco is my current set up. i ALWAYS end up going back to stock because i find it alot more fluid out of the box state than any custom rom.
battery life for me theres a marginal bump up. but i keep the kernel as is no tweaking besides color calibration.
and of course that part depends on many variables in your particular situation. apps,managing apps, how much you use the phone etc.
i am no app hoarder just the basic essential apps that get my through the day.
i can honestly say this is my perfect set up for my N4. Stock with root and francos nightly kernel color tweaked

Did that before flashing anyway. And after restoring stock system.img and several times in between.. dalvik and cache both.
Might have to download a toolkit to install it.. Don't know if it will make a difference or not
Tried the milestone boot.img also. Does not even move past "Google" in this case..
