best combination of ROM/kernal for battery life - Nexus 7 (2013) General

Post your results here. Also if you could say what CPU governor you are using, that would be great.

Running vanir with Jassy kernel oced at 1.9 ghz governor ondemand. Runs great so far

Personal opinion. I can tell you what I get with mine

Not another thread like this again. Everyone's device will yield different results. We all use our devices differently. A particular ROM/kernel combo on my device will not yield the same results for someone else. There is no best ROM/kernel combo that is best for battery life. Try out a bunch and find what works for "you".

Best kernel for stock rom?

I prefer balanced battery and peformance. Please advice. Thanks
All kernels work differently for different people. Try a bunch and see what works.
-Brought to you by Marino's Nexus 7-
Franco kernel lets you overclock the gpu to what ever you want (416-750 and anything in between) so with that in mind you can create your own balance of battery vs performnce.
You cant overclock cpu but honestly it isnt needed.
Also with his latest release r25 th whol devive is much more responsive. Touchscreen etc.

i'd say go franco or trinity.

Good battery life kernel?

Currently running the sabre tooth kernel, runs very quick - but device seems to die rather quickly. Any other kernel that people can reccomend for the WiFi nexus7 that offers better battery life with minimal lag? Current ROM is also the sabre tooth latest build.

Try Franco.
http://forum.xda-developers.com/showthread.php?p=29990763
I'm using M-Kernel and I would say that this is a very good kernel in terms of battery life and performance, although this is not geared for performance per se, but this kernel is more of a balance between the two. Other users reportedly are happy with the Omega Kernel, its still relatively new, but the reviews are good. Go try them out.
I like franco and lean kernels. To be honest, I cannot really decide between these two. The best is to try them both. They are very well tuned, so there's absolutely no need to overclock - this is very important to preserve battery.
Anyone able to post a link to the Franco kernel? The one in his thread is not loading the webpage where it is housed.

There's also a thread in one of the subforums that lists most of the current kernels and runs each one through the same tests to rank them by speed and battery life.
M and Franco seem to consistently be the top two for battery, but I wonder if that will change if Clemsyn's is ever updated.

I've been using Matr1x kernel for quite some time now. It's the best I've used. I've tried Faux and Franco and those didn't work too well for me. Try them all out though and see what works best for you.
Sent from my Nexus 7 using xda premium
Franco's latest kernels have been very battery friendly. They're amazing. You do kinda sacrifice (albeit super tiny) performance though.
If you care about performance more, try Motley's. His kernels are reasonably battery friendly, but doesn't sacrifice any performance.
Trinity and Matr1x are my preferred kernels due to their speed and overall stability.
Battery go for Franco.
Hmm. I think I'm gonna try out Franco. I'm on the go a lot and battery life is a bit more important to me than performance. I wish the nexus 4 was more than a 2100 battery...

Yes to be honest Franco's kernel is the only kernel I'm confident with when I go out LOL
must say though the hunt for kernels has been remedied by google, for me at least. their 4.2.2 is insane. im getting 21.800 in antutu without touching the clocking frequencies. im getting 1-2 days of use and still 4-5 hours screen on. its reliable, it wont crash or screw up otherwise and best of all i dont worry about it, at all, its enough for me to settle and think of kernels no more. only thing that really bugged me on this plattform were the colors. but thats solved now. if you wanna try: http://goo.im/devs/paranoidandroid/roms/mako/ start with contrasty and see if you can live with the brightness, that one has probably the nicest colors that can be possible with this panel.

4.3 reduced antutu score or its just me..

K guys.. I am not sure if its 4.3 or something else.. Can someone confirm.. I used to get 18000+ on my 4.2 n4 and over 24000 with faux overclocking kernels for 4.2
Now i am getting 14000 - 16000.. With 4.3..

Try the S4 dalvik patch that's floating around here. Boosted my score to 20k+ on PA 3.99 with stock PA kernel at 1512/1512.
Using this combo as my daily driver since a week and no problems so far.

What kind of numbers did you get before the mod?
Sent from my Nexus 4 using xda app-developers app
Around 16-17k if I remember correctly. Also don't forget that heat throttling is pretty aggressive on the N4. So make sure your device has cooled down before the next run.
Pro tip: put your N4 onto a cold ceran stove when benchmarking. They're made to conduct heat efficiently and will keep your device cool
Well I wouldn't give those numbers too much credit...
they represent more the settings that you enter, than device performance.
I for instance use the latest franco Kernel. With the settings I use every day (interactive governor, default clocks), I get arount 15-18k in antutu. But the device feels as snappy as hell in normal usage and gaming.
If I switch to performance governor, ramping the minimal and maximal cpu clock up to 1512MHZ while raising the cpu throttling from 65 to 90° I reach antutu scores in the range of 20-22k.
But I obviously would never ever use these settings every day.
That beeing said, these numbers do not really represent how the devices behaves in every day usage, which is much more important to me than any number, a benchmark puts out.

I have a couple of questions:
It's your phone still working like it should?
Do you really care about the scores you get to be able to enjoy your N4?
Do you think the scores of benchmark really say everything about your phone?
If you compare a S4 or M7 with a N4, and in one test (by chance) you get the same scores, do you think your N4 has the same power as a S4 or M7?
Stop worrying about benchmark scores, I used to be like that bench-marking all the time, at the end I just got tired of it!!!
Now I just enjoy my phone the way it is.
Good luck!!!
CM-10.2 and CM kernel got 20728

[DISCUSSION]Governors and Schelduers

Okay,so i made this thread so that development thread become less spammed with your questions.
Please,share your opinions here and ask questions,someone will answer you,and share your screenshots of battery life.
I personally use PegasusQ+VR,it gives great performance and good battery life.
My second choice would be Abyssplug+SIO,especcialy for the hotplug feature.
(In case you dont know what Hotplug is,its the feature that turns off the second core when your phone is not in use.)
I cant decide wich is better,tommorow ill test Hotplug+sio,and ill post screenshots of both tommorow.
Please,ask any questions here,dont spam Benz's threads.
Thank you

Hi, can you tell me the best combination of governors to use. I'm using latest cm
10.1 maclaw build with hotplug and noop, but i think CPU its not sleeping cause i loose about 5% battery in 2hours withought using my fone at all. Thanks
Sent from my GT-I8190 using xda app-developers app ?
Hotplug governor is indeed a joke, at least in Maclaw's CM (not surprised). There is no way to set it up for low battery drain /and/ reasonably smooth functionality. Right now I am using Ondemand + CFQ while playing with the powersave bias and up threshold parameters. The only thing I wish I had from Maclaw/Benz's kernel is the vr/sio schedulers.
You have VR and sio schelduer in Benz's kernel,and Abyssplug governor with real hotpulg feature,when you dont use the phone cpu shuts down one core and the remaining core runs on 200Mhz and 1% usage.

I would gladly use that kernel if it didn't have the dirty flickering fix. And if it didn't require CM10.1 reboot edition.
Also, when I was on CM i ran a logcat with hotplug activated. The second core would often reactivate even if the phone wasn't doing anything, with the screen turned off, then soon turn off and after a few seconds repeat the process. Maybe this phone really needs the core.
What flicketing fix? I got no flickering on the latest Maclaws cm and benzs kernel..and it shuts down the core,you can see with system monitor when your screen is on..dunno for screen off,but i get like 1% drained for a hour with screen off

The 63 fps refresh rate, which "fixes" the UI flickering.
And yes, I saw the second core turning off myself. However, I am not sure if it keeps being off enough time.
Well in maclaws rom i dont have flickering,but in olivers i had. I dont know,i got decent battery life. Not good as stock,but its ok

And what exactly is so wrong with 63 fps refresh rate? Will your screen fry because of it? No it won't because it can't. Will your phone explode while being used? No it won't because it can't. What's the issue here then? Tell me.

Have you considered the battery drain implications? The battery is weak enough as it is, a higher than normal refresh rate only wastes more GPU power thus more battery.
