Battery Life on CM7 (AOSP versus Sense)

I've been running the latest nightly (20120722) for a few days now with less than stellar battery life. It seems that everytime I run an AOSP rom the main battery culprits appear to be cell and phone idle, where's with a Sense rom, it' the screen. I have a relatively new battery. I'd say moderate use, typically.
Anyone have suggestions on getting better battery life with CM7? I'm running the stock kernel at 245/800, ondemand, deadline. Also running V6 supercharger at 5.
Any advice is greatly appreciated. Thanks!

I've gotten 12+ hours today of cm7.2 7/15 nightly and barely at 50%
Did lots of recordings and such.
Dunno
I don't use the v6 script, or do any mods at all.
Just run it as is.
Stock battery too.

Yeah I've gone back to 7/15 to see if it's any better. I seem to remember it being better; I'll report back later today. Still curious why cell standby is the main battery eater on CM7 (or AOSP ROMs in general) as compared with say, SSX or newSENSE, which was the display...

Aosp shows true signal where Sense won't. So AOSP having a cell standy over display sounds about right. Sense always thinks it has signal and AOSP has no signal thanks to sprint. In my area Sprint blows, so that's what I *think

This is better.. I went back to the previous nightly (20120715) for a few days now. Still moderate use.
I'm currently running the stock kernel at 245/1.21, ondemand, deadline. Without V6 supercharger and I didn't flash the ICS theme either.
Perhaps the 20120722 nightly did not play well with my device.

That is a lot better! Glad it's working better for you now.

If V6 SuperCharger is not setup correctly, or the setting is to high. Your Battery life can take a hit.

Best ROM / KERNEL

Hey guys I just got my second nexus 7 (dropped/shattered my first one) and I have been away from the forum since.
I just wondered what everyone thought as far as which ROM and kernel was best for daily use.
Honestly the most important feature for me in a ROM is the kill app feature (aokp or long press back).
As for a kernel, im looking for a well balanced performance/ battery life.
Thanks guys for your input.

If you know that already why did you start this thread?

I like Team EOS's nightlies. I'm using faux's latest beta kernel too with the new CPU driver. Can't comment on battery life personally (although faux's new kernel has reports of better battery life), but performance is quite nice.
May or may not be the best combination though, it's just what I'm using now.

I'm a big fan of Paranoid Android. It allows you to choose between phone, tablet, or phablet mode for every app. Also, it allows you to choose between small tablet, large tablet, phablet, and phone workspace.

These threads always turn into bickering fests and drama which is never good. Nothing against you OP but I have to close this one as nothing good ever comes of them unfortunately...
Just search around and read all the threads and its pretty easy to get an idea of whats best or used by the majority.

[Q] franco kernel, matrix kernel, ???????

Hi to you all,
Have you done any benchmark quadrant type with modified kernel?
For my part in stock kernel I was running about 5050, which is very promising when the capabilities of the beast!
I look forward to the first kernel in flashable zip Franco associable with a rom type aokp
This association did wonders on my old galaxy nexus!

Not massive on bechmarks and a big fan of Franco.
I cant tell any day to day difference in the performance between any of the kernels currently out however Matrix is giving me more batter life, (more screen on time) than the others.

ok, i wait and see when franco kernel will done !!!

I just flashed franco kernel myself with paranoid android. Going to see how it runs for a few days.
For those who have used matrix and franco extensively care to share your thoughts, pros/cons for each?

However, if you put any trust in Quadrant scores you could use them to prove that dancing naked for 5 minutes in your garden affects device performance

I am using Trinity. Love it so far.
Tried faux123, found it undesirable with current my settings.
Didn't want to commit to non-stock ROM for franco. Would love to try it though.

I'm on xylon ROM and matrix 3.0 kernel

Running franco kernel and using my phone as I normally would during the day. I don't see any particular battery life savings. I think I will flash matrix tonight and see how it goes tomorrow.

Yes sir, franco also uses stock rom.

I have gotten the best battery from matr1x compared to Franco. I got 2 1/2 hr on stock, 3 hr 40 min on Franco and 4hr 40 min on Matr1x I'm still running stock otherwise but I think I'm gonna try experimenting with Roms tonight. Any suggestions I want to stay as close to a stock look as possible but I'm willing to bend for battery.

Are you using interactive as the governor? It is more tweaked than ondemand on Franco.

Yes I was using interactive but I only gave it about 2 days. I needed to probably give it more time. But I'm loving Matr1x at the moment. Thank u for your suggestions they are much appreciated

You must wait at least 1 week, in order to get the kernel settle in your phone..

That is outstanding. But how in the world is it possible that you have a "screen on" state without being awake?
I have been fighting battery issues for so long now, I'd really like to get to something as good as what you get...

i get 5 hours on heavy use until i hit 10 % well my setup is in my signature on light use i am sure i can stretch it to 6 hours with brightness on auto and wifi is on most of the time

battery life is never going to be better for me unless i uv. the previous setup, i used cm 10.1.2 stable with matr1x kernel. i uv and set the max cpu to 1350. it was really really good. i can use the phone from 8am to 9pm.
now currently using aosp 4.3, the default setup battery life has improved a bit compared to 4.2.2 stock, but after semaphore kernel installed and uv a bit, even with max cpu at default which is 1.5ghz, battery life has been really great.

I've terrible battery usage after 4.3 update. I never had any issues before but now I get 20 to 30 percent drop during the night when before it was under 10 in the same scenario.
Android os Showing 6h usage...
Any help on sorting this out highly appreciated.

Battery life has increased a lot for me.
No heavy usage, I know. But still awesome compared to the stats I had when I bought my nexus 4

Just out of curiosity, are in you the US/North America?
I had the same issue of losing tons of battery to the OS overnight. I reflashed to an older version of the modem. Most of the people I have seen so far with these symptoms have been in France and India. Must be something about the cell services and how they interact with the phone.

@Calebz: I'm in Ireland.
I've restarted the phone since and the battery usage is back to normal, will see for how long.

Buying a Nexus 4, What should I know?

Buying a Nexus 4 after sticking with the Samsung Vibrant for so long. Anything I should know about the Nexus before making this upgrade?

You should be the one telling us what you want to know, hehe.
Get the 16gb variant as it doesn't have a micro SD slot and I find 8gb is not sufficient.

Sometimes the battery life SUXX
Today i got 2h 40m screen on time with some 3G and some Wi-Fi.
On wi-fi only i get 5hours max with custom kernel, under-clock to 1.2ghz and under-voltage.

Just get the Nexus 5. The N4 is almost 2 years old.

No SD card slot, its pure android; don't expect fancy ui design. Not a lot of customization like touchwiz or sense; its simple.

Stock rom 4.4.2, Xposed module and franco kernel r204

If you don't want to get a cover I recommend getting a screen protector for the front and back. This phone is awfully slippery.

I personally have great battery life from my Nexus 4. Stock, Xposed and Franco just like the previous poster. Had a vibrant long ago. If you're upgrading, you will be very happy. Of course, price would be the only reason to take a Nexus 4 over the 5, but you won't be disappointed with either.

Audio mods is a must for N4. And for battery life it isn't perfect, but still pretty good. I've usually get 3 days with 2.5 SoT (moderate usage).

Just sharing my thoughts between Nexus 4 and Galaxy Nexus... I'll still prefer the battery life and screen of the Nexus 4..... But the fact that my Nexus 4 had approximity sensor is really unnerving sometimes.
