Best kernel for battery life with Fresh 3.1.0.2?

I've never cared about battery life before because I'm typically near a charger however I'm going to the beach for a few days and will need my phone to last.
What's the best kernel/set up for me if I'm running Fresh 3.1.0.2? I don't care about performance, fps, mflops, etc for these few days as long as the battery lasts and the phone is stable. I have setcpu on my phone but don't really know how to use it.

The latest cfs kernels are supposed to focus more on battery life than performance. Do you underclock cuz that's a big help too.

At 998 max now, where should I be? Which cfs one?

I'm running Fresh and Netarchy's 4.1.8 kernel.Creating a set CPU profile for when the phones screen is off will increase your battery life quite a bit.My screen off profile has the CPU max at 245 ghz and the min at 128.You can also scale back your max from 998 mhz to around 500 mhz and save battery without your phone being so slow that its really noticeable during normal use.

Interesting. What kind of battery life do you get? I thought I read a while back that going below 245 was a bad idea. Guess not?

It's more stable with the newest kernels. I'm set at 245 min and max when the screen is off and I usually see a 1% loss every couple hours but I haven't paid a lot of attention to it lately cuz like you, I'm usually near a charger. Battery life while using the phone still isn't great but I kind of expect that from a phone like this. There are some good battery conditioning tutorials in the forum that help quite a bit too.

Here's my usage for the last week.I go off charger at around 7am and usually have about 70% charge remaining when I get home at 5.

[Q] Battery mA

Hi
Baterry usage
29/30ma in standby, isn't that too much? When IDLE
HD2- normaln/ idle 3-8mA
Normal for G2 is ??
Thanx
Virtuous v1.0.1 (HTC Sense 1.85.72.2)
1.85
T-mobile g2
usage only 2g (EDGE)

yeah thats fairly normal matey, mine is always on 30ma in idle and 250-300 in use.
my battery lasts a full day sooo i dont mind
my old hd2 lasted me a whole day as well.
i dont mind much difference in battery life between the two phones
just make sure you use setcpu and make a profile so that when the screen is off the cpu min is 256 and the cpu max is 256... you could set the max a little higher if you want but i have no problems using this setup.

Currently on miui and I have 3-8 on idle on average. I always check my ma usage with current widget.

Edit: Damn I feel like a retard. I didn't see that I was in the G2 forum. I got a G2 also. It was my nexus one which was clocking in at 3-8ma sorry. Still worth a shot to try it out.

cheers matey
quick question what is miui like?
im guessing from the looks of it its like android with a smoother interface like ios

What kind of idle consumption are other people getting?
I feel like mine is kind of high, but not sure. G2 stock OTA rom. Perm rooted and Oced, running SetCPU. Currentwidget says somewhere between 37-40mA in idle. That gets me something like 30-33 hours of pure idle on wifi calling.

My DZ (currently running stock rooted Sense 1.82) idles at about 28mA if I have Wi-fi/data off, 2G only, and SetCPU locking the CPU to minimum when the screen's off... about 32-35mA with Wi-fi/data on and 3G (SetCPU still locking the CPU to minimum when the screen's off)

Slow/Laggy CM9 Nightly Fix!

I'm not sure if anyone else was experiencing lag from the new CM9 Nightly like I was after I flashed it.. So I played around with the options and noticed that the CPU governor under "Performance" was set to "Interactive". I switched this to "On Demand" & checked "Set on Boot" and man this phone flies now! Also make sure that the min and max speeds are set correctly.

I dunno, maybe your battery life is going to suck now lol. Let us know how the drain is. If I weren't at work right now I'd be playing with the latest nightly myself.

CM9 is Great! Flashing LU6200 and used X2.

You have succesfully flashed CM9 on LU6200 ?

On demand governor draining more battery then interactive one?

Much snappier for me too. Can't report on how it affects battery life yet. With this phone and the newness of the ROM, definitely keep your charger handy.

thank you, I made these changes.
I did a bit of the google to try and find the difference between interactive and on-demand, the nomenclature sure seems similar, but could not find any descriptions of the 2, anybody know?

http://wiki.rootzwiki.com/CPU_Governors
Ondemand
Quickly scales up the CPU frequency once there is sufficient load, and then quickly scales down the frequency once the load is no longer present.
* Pro: Good performance, decent battery life.
* Con: CPU frequency can constantly shoot up and down, causing more power drain than staying at an "ideal" frequency.
Interactive
Quickly ramps up to the maximum allowed frequency, then slowly drops the frequency once no longer under load.
* Pro: Faster to ramp up and down means a snappier response from the device.
* Con: CPU will run quickly for a few moments after it is no longer needed to do so, resulting in longer periods of higher power consumption and heat generation.

I don't notice a major difference in battery drain yet. Still mediocre. But I am willing to sacrifice some life for the absence of lag. I almost reverted back to gingerbread before discovering this minor change fix lol.

Thanks Namuna

THANK YOU VERY MUCH FOR THIS
actually i have a much better battery right now and an almost lag free phone !

I do not recommend enabling KSM as posted above. I found out that ksmd process utilizes cpu by 3-5% for hours!!! It drain battery on my eyes!

Post a Screenshot of your battery drain in the settings and give details about your setup. And what is fast in your opinion? 1% /hour?
Maybe you should buy the extended battery kit?

try flashing different kernels and see which one suits u the best.every phone is different.u may also wanna underclock and undervolt. also change the rom may b if changing kernel doesnot work.ine suggestion.XenonHD rom with its stock kernel.

The stock battery is a joke at 1800 and the extended is 2100...I had both and both sucked although the 2100 was a lil better. I have the 3800 Seiko battery now and that will last me all day. Makes the phone thicker but its better then charging all day and worrying about what's killing your battery.

Turn off features when not being used like data NFC GPS.
Also avoid auto task killers

How much does it drain in one hour? Battery drain depends on many factors. The mains ones would be what kernel and ROM you are running as well as what "features" you have turned on. For example I am running CM10.1 with the stock CM kernel and I usually get around 16-18 hours of battery life with 1.5-2 hours of screen time.. that is with all of the features (gps, NFC, etc.) turned OFF.

How on earth can you drain a 3800mAh battery in one day? Nonstop internet radio AND 3d gaming on full display brightness?

I am currently using PA rom with franco kernel. Normal day = roughly 13-15 hours ish.
By normal day I mean around 30 minutes of talk time, about 1 hour ish web browsing and like what, 30 minutes ish of youtube? Of course, sometimes I am free and end up playing games on it for couple hours lol, but the stock battery seems to be plenty enough to me.

My battery makes it about 15-17 hours,with about 1 hour gaming,1 hour browsing and talk time around 1,5 hours...Xylon + Purity Kernel!

It is what it is. This is Wi-Fi only on this charge:

Turn data off when not using it. You can download a widget for that.
Keep screen brightness down low.
If rooted use setcpu and choose a screen off profile of 350mhz maximum - I find this a real benefit.

Battery drain on 4.2.2

Been having battery issues ever since I flashed a 4.2.2 ROM.. I think its the modem. Being on like over drive, draining my batt.
Or is it 4.2.2? I tried all the 4.2.2 Roms that there is for our phone. And its seems to drain at the same rate every time. I don't know of its just me or can my radio be the cause of it. Or android 4.2.2??

Battery Drain......?! Try Battery Not Holding Any Charge!
I've kind of got a similar problem. Can't quite figure out what is causing it though. Everything was fine until I updated to tha latest nightly last night. It slowly took a nose dive after that. It actually died all the way out on me while sitting plugged in. Now, as I stated in the title, it won't hold any sort of a charge whatsoever. Every once in a while I can get it to boot up but almost instantly it shuts right back own. Can't seem to boot into recovery either, but have gotten it into Download Mode pretty easily. That's where it'll remain on for the longest duration, but still not long enough to be able to reflash anything to it. The battery state check said the battery health was good all the way until it completely died on me the first time. There has been no moisture or other damage done to it in an kind of way either. Any ideas as to what exactly the issue at hand may be?

Sounds like it might be your battery...know anyone with an s3 that you can use there battery for a bit to see if it charges...if so then its your battery if not might be the ROM or phone.

I'm running the most recent PACman ROM, which is 4.2.2 and what I do is set my governor to interactive and my I/O Scheduler to SIO. Running stock kernel at the lowest min and highest max, I can get almost a day and a half out of a charge. My trick is to toggle things when I'm not using them. I mean all the time. Screen brightness never above halfway, no haptic feedback, no live wallpapers, and I'm always clearing my recent apps. I don't know if this'll help you any but that's my battery saving procedure.

I really don't know anyone with an s3. Seems Apple has everyone around here convinced they're better. HA HA! That's a great laugh! Seriously though, there is a used cell phone shop I'll go talk to though. As for my kernel settings go I run interactive, on demand, 648 & 2100, under volt everything 100, and either raise or lower all other settings within one point from the least or maximum it could be. Been running that since I got the phone in September without any problems battery wise whatsoever. I'll start with checking the battery though and see where that journey leads....... Thanks for the thoughts and suggestions.
