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

Glados has great battery life.

For now, I've already tried out a few kernels and ROMs.
I flashed euroskank's ROM. it's based on CM10. This one is great. I eventually switched back to it.
Glazed is good, too. But the battery life is not as good as Euroskank in my case.
CM10 nightly, this one is strange to my unit. Because I have the randomly screen unresponsive issue in my nexus 7, the first time I flashed CM10 nightly, the screen got really strange and registered my one touch as two. It made me hard to even go through the initial setup so I gave it up. Still, this could be the problem of my unit, not the CM10 nightly.
Another strange thing. I saw a lot of people recommending trinity kernel. But when I flashed it over Euroskank Rom, I didn't know why but the battery drop 1% every minute. This was also an identical incident because I didn't see it anywhere in the forum that people had the same issue.
Anyway, as the result, I switched back to Euroskank and happy with it.
What if everybody post the ROM the kernel and make a benchmark with this https://play.google.com/store/apps/details?id=com.aurorasoftworks.quadrant.ui.standard&hl=en using the stock cpu and gpu speed?
I will post my results tonight
Stock Kernel Unless you really need a custom kernel, get one where you can lower the cpu voltage

yep. On stock I was getting 3-4 days battery. On Trinity I'm only getting 1-2 days and I've been using it less.
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.

I'm seriously considering flashing carbon. I love all the customization involved. However, I really want a stable ROM. Is carbon stable enough for everyday use?
Sent from my Nexus 4 using xda app-developers app
Best bet is to just read the thread. Yeah it sucks having to read a ton but by the time your done you will know if said ROM is stable enough for you
Sent From a Freaked out Nexus 4
Been running carbon for a few days now (with franco kernel) and I've been impressed. Battery life seems to be great especially when sleeping (very little battery drain) but that could be the kernel.
The customizations are great and offers just about everything I could ask for. I would recommend you take it for a spin for a couple days.
Its been a few hours; why haven't we heard from you? You asked a question, we responded, we, or at least me, expect a response.
This is important to the ROM developer if they're paying attention but more important to the end user.
Feed back please!!!!!
I tried Carbon also, but randomly the phone turned off and stopped working. When i tried turning it back on, it would get stuck on the Google logo, then it would move to a black screen. This happened spontaneously. After a few failed attempts i got into recovery and flashed a previous ROM, which fixed the boot problem. Therefore i wouldn't really recommend Carbon, but it did have all the features i was looking for, and quick boot up time also. Give liquid smooth a try, its been running great with the kernel it comes with. I've been getting over 4 hours screen on time, and usually its 100% brightness.
Alright appreciate the feedback. I'm trying xylon ROM currently and kinda hesitate on carbon now. Especially since reading the threads I've noticed people have little hiccups with the ROM. And dude sorry I'm not on xda every day.

experienced user told me that Stock(AOSP 4.2.2) is better than Custom (CM10.1, AOKP...) (in terms of Battery life.)
is this true? maybe someone test?
i have Nexus 7 3G (AOKP off + franco Kernel)
It's impossible to give you a truly correct answer because there's too many variants which can make battery life differ.
As things like apps, usage, ROMs, kernels, mods, the device, tweaks and many other things can all have different effects on battery life, it really is dependant on the specific situation.
So if I was to have the 3G model (as you have), be using the same ROM and kernel combination, have all settings exactly the same, have exactly the same apps installed, use the apps for exactly the same amount of time and have the same mods/tweaks installed, we could still quite easily have our battery life last a different amount of time.
Due to that, that's why it's always best to just test them out for yourself so then you'll know exactly how your battery will perform in regards to your usage

The ROM makes little to no difference whatsoever. Battery life is more affected by the kernel and your own individual settings.

But some ROMs claim to have better battery life than the others (CodenameBattery, SuperCharge Series). Are they talking nonsense?

Odp: [Q] Best Battery life. Stock or Custom?
I use stock 4.2.2 rooted in two weeks now, and the battery is very good. Try to stick to stock in one week or so.

Some could absolutely be talking nonsense but others could actually be telling the truth.
They could have certain tweaks in place that will indeed improve battery and could also have more power saving apps included. There's so many variables that without actually testing them out for yourself, there's no way of knowing whether it will have better battery life or not.
I use a custom ROM on my gnex simply for color control, but in my experience custom kernels never improve battery enough to make more than a very minimal difference. I stick to stock with my 7 for multiple reasons, one being certain EA games won't download data while using custom kernels. You'll see people claiming custom kernel's get them 9 hours display time ect... Well I've gotten that on stock depending on what I was doing with my 7. My average is usually more like 5-6 over 2-3 days as I use it more for gaming than anything.

Like previous members have stated, it's not possible to give you a definite answer as to which gives you better battery life. When I received my N7 I rooted and installed a ROM and a kernel. Ultimately I revert back to full stock android for many reasons. One, battery life was much better on stock kernel than a custom one. I didn't need a custom ROM either. Only on my N4 would I need custom software installed because recently my mother has been using my N7 a lot so my N4 is what I use most now.

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

yes i notice a difference in my battery life. nothing big but i can tell you theres a difference and every little ounce of juice helps im the type of person who always reups over night and im usually at around 35% by 10pm after a full day of use
I prefer bricked (note my signature) but Franco's is nice, probably the most popular one out there for either N4 or N7.
help ?
Sorry if this is a bit out of context, but Since I have less than 10 posts, I am unable to comment on the most suitable thread. Searched Q&A and other threads as suggested, found conflicting replies.
My problem: Flashed stock ROM on my Nexus 4,(jwr66y) but am unable to move past the boot screen ("android") while flashing franco's kernel for nexus 4 OSAP from franco's thread regarding the same.
Tried the boot image from franco's post as well as the boot image from the occam jwr66y post. Does not move past the boot screen. Help?!

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..
