[Q] Which custom rom has the lowest battery drain?

Hello
Thread title says everything. Want to know whether a sense based or an asop rom has the lower battery drain. Maybe somebody who has already had both types of roms on his DHD could post here some informations.
Thanks in advance.

Usually an asop one uses less battery but its easy enough to have a sence based ROM and flash an undervolted and overclocked kernel to save battery.

Yeah but uv/ov kernels are still not available for 1.72 based roms.

They are all the same mate.

Display takes proportionally the most out of your battery, no ROM can quite compensate for this.

Kernals

Sorry guys if this is a bumped thread.. Couldn't find one that helped me at all.
Alright, I would like to know, What is a kernal. Ive flashed almost every rom possible but i havn't done anything with kernals.
Thanks

I've heard it stated as "a bridge between hardware and software." They control your processor speed for certain circumstances (screen off) and what voltage your processor gets at certain speeds. It can also come with different things like audio boost and enhanced multitouch capabilities (3+ finger input). Just remember to flash a sense kernel if you're on a sense or senseless ROM, or an aosp kernel for an aosp ROM. I always wipe dalvik cache and cache partition before installing a kernel, just to make sure theres going to be no problems.

So what your saying is , different kernals do different things twords performance ? And what is cm 7 rc2?

Correct, there are some overclocked kernels and some that are stock speeds, plus all of the different tweaks that can be applied. And CM7 RC2 is a ROM. CyanogenMod (ROM name) 7 (version) RC2 (release candidate). Its a pretty popular ROM.

Lmao no man, im running cm7, love it to death. What is CM7, aosp ? I know its senseless.

So not to jack your thread but its highly related to the question I've been asking today. I understand the description of a kernel above but then what would be the main differences between the kernel and the Rom of a device? Are kernels simply used to modify aspects of the phone such as processor speeds or do they also have something to do with the UI?
Sent from my ADR6300 using XDA App

I dont think they have any effect on the UI

So besides just processor speed,what else could a different kernel affect?
Sent from my ADR6300 using XDA App

CM7 is AOSP.
Kernels don't affect the UI, they control processor speed mainly, but they can also come with patches that boost audio levels and enable fast charging or trickle-charge (SBC [when you charge your phone normally, it gets to 100% then stops charging regardless of being plugged in and runs off of the battery power til about 90% ish resulting in the infamous dropping 10% battery in like 5 minutes scenario. This mod enables the phone to drop its charging current once it hits 100% instead of turning off completely, maintaining the battery at 100%.]). Pretty nifty stuff

I'm not exactly sure about the BEST, cause different things happen to people when using the same kernel, but I've been using chads incredikernel from 3/18/11. No problems with it so far.
Sent from my Droid Incredible running CM7 RC2.

I heard that kernel had smartsss governor ? What's that do .
Sent from my ADR6300 using XDA Premium App

Yep, it does. I'm not too familiar with what it does, but I've heard it basically favors lower CPU speeds, saving you some extra battery life. I've yet to notice any lag or slowness from running that governor. I get pretty good battery life with this kernel too, so I figured I'd stick with it.

Would calling a phone a car chassis, a ROM the motor and a kernal the driver be a good analogy?

Best custom ROM for LG Nitro?

In your opinion, what is the best ROM you've used?

HO!NO! Full Throttle but I'm still testing pA 2.35. Wish we had a oc/uv kernel for JB/CM10.

It would be nice. Tweaks are good for now but remember, nothing is impossible. It'll happen. Just give it time.

I use CM9 RC1. For some reason it works much better than RC2 and the stable version on my phone.

CyanogenMod 10 was just released as stable for us, I believe soon enough they will develop and overclock kernel and we'll be all set.
However, does anyone think that a downgrade to HONO Full Throttle is worth it for the ability to overclock? From what I understand, it is a small OC of about 20% to 1.86Ghz. Does it really make that big of a difference?

If you want try it then make a backup and test it out. Full throttle is a step back and I prefer the JB ROMs. But its worth a shot. Just watch your battery stats with OCing, Typically a higher CPU uses more battery.

Full Throttle is my daily driver. It's a small OC but it's better than nothing. My Antutu score hit 7200 and my Quadrant averages 3750. I also OC the GPU even though its default is already OC'd. The battery on Full Throttle is FAR better than any JB ROM I've used, so far. On a normal day (txting, couple calls, browsing, ect) I get about 20+ hours w/ 3hrs of 'Screen On' time. It may be a downgrade, but it's best I've used. I also have my UV settings set to best battery life w/out causing reboots. Love Full Throttle! Patiently waiting for HO!NO! to commence dev work and see what else he has to offer.
EDIT: I just leave the OC stock @ 1728Mhz as well. I tried 1836 but after playing a game for a bit it overheats and reboots. Also doesn't pass a stability test @ 1836, but every phone seems different on what clock it can handle..

Okay, I've tried both.
From a very limited usage, I am going to conclude that CM10 stable is currently the better ROM. Being able to overclock ~20% on an older ROM does not actually match the performance boost of upgrading to a new, more efficient ROM. Now if only we had more developers for the Nitro.

Wait. So u asked today if it would be worth trying Full Throttle, and now you "have" and conclude cm10 stable is better simply b/c it's newer? JB is smoother, yes, but I seriously doubt you gave the Full Throttle ROM a proper run (2-3 days). My 4 days of cm10 "stable" was riddled with reboots and battery drain equal to about 7%/hr. Smooth, yes.
EDIT: If you haven't tried it, pA 2.5x is pretty cool. It's based on CM10 stable now. The battery life is horrible, but there wasn't any annoying reboots.

I beg to differ on the reboots... actually, no. I call them random shut-downs. Had 3 since flashing 2.55, but I'm still sticking with it. X0dus, I just don't understand how you get so much better battery life on FT than any of the CM10 variants. I'm not disputing it, I just don't get it. If anything, the experience I had as far as battery life goes was about equal. In fact, the best battery life I've gotten so far was on an earlier, buggier version of CM10.

About an hr and half screen on time w/ stock battery. Not a normal use day due to 10hr shift but still use

Mother of God... that's absolutely insane. Even with the Hyperion extended battery I couldn't get that kind of time... I don't do much calls or texting, no games, but I do a good bit of web browsing. Even on FT I couldn't pull those numbers.
Although I did pull something like 1 day 6 hours on that CM10 version I mentioned earlier... had about 3 hours screen on time.. but again, extended battery.

Nice. I love the performance of JB but I can't give this sort of battery life up. All JB ROMS drain is terrible for me. I swear it's the uv'n I do with FT that helps. If I go any lower with uv I get reboots.

Henry's one. I used his old one (the one build before current). It had no issues and worked great.

You Mean Cm 7.2 based
Sent from my Wildfire S A510e using xda app-developers app

I think MIUI v4 is the best, and the battery life is not so bad (MIUI roms' battery life is always a bit worse than other roms').
I tried the SnapSeries one too, and the battery life was very bad there, it just drained my battery (my phone almost discharged during the night from 100% battery, and I had no wifi or anything turned ot). But probably it's been fixed already, and then it's worth a try.
And although it's just a beta, you should also try the JB based MIUI 2.10...

[Q] Increasing Battery Life of CM10.1

Hey guys...
I'm currently trying out CM10.1 and I'm loving it.
As its better than any other cm based roms like PA, Pac man etc
I'm really disappointed from the battery life, it drains so quickly
I tried NEAK kernel but it didn't help, can some one help me out to get good battery life out of cm10.1?
Thanks in advance.

I use carbon rom and neak kernel and i get about 22 hours with 5 hours screen on that's the best aosp rom i have seen for the battery
Sent from my GT-N7100 using xda app-developers app

I got 10 hours on average(Which i guess is ok)when I was on Cm 10.1. I used to set CPU to about 400 MHz when I was just listening to music but 200mhz when it was sleep. It was a hassle to do but it did help.

Im curious aswell. Im running cleanrom ace 4.9 and im getting around 1day 12hrs with 4 hours screen on. I want to move away from stock again but can never get more than 16 17 hours on aosp.
Sent from my GT-N7105 using xda app-developers app

I heard devil kernel is pretty good with battery on AOSP, also try downloading greenify from the play store. It take apps that constantly run in the background that aren't in use and hibernates them. I'm a heavy user of youtube and radios and I get around 20-24 hrs. But on light days I get over a day. I'm currently using ProBAM

The most I could ever get was always 5hours screen time and thats after using Greenify, Droid wall and uv/uc with slimbean, carbon and pa. I've heard of some people getting upto 7 hours on aosp but they never seem to share the setup, most likely in airplane mode though. Ultimately battery life was always an important factor for me so I reverted back to tw roms. Sad.
