Ever since i flashed francos kernel for the first time i failed to see any difference whatsoever in batterylife or performance. 4 versions of franco kernel later and still no change. Even bought his app and tried undervolting. I accidentaly uv'd by 100 in the 700 category and none of the side effects were happening so i tried undervolting all by 200 and even setting on boot. Nothing happened. I then flashed jame bond kernel and nothing happened. When i tried flashing glados kernel it just froze on boot. I experimented with all of them for at least a day and except glados which didn't work they all showed no difference than stock regarding battery life or performance. What could be the cause of this?

Kernels don't have the profound effect you might think on this phone. Not nearly as much as devices I have had in the past.
I'm aware of that, but still. No difference whatsoever? Even when i intentionally try and break it by undervolting by 200?
Sent from my Galaxy Nexus using Tapatalk
What did you undervolt by 200? Some speed steps can get away with that.
What ROM are you using?

Adrynalyne! Its good to see you here!
Yeah, on the Fascinate, Kernels had much more of a profound effect. I can't say the same for this phone. But the OP said that he purposely tried to Bork his phone to see if it worked and it didn't even touch it. That's really strange. I can purposely try to Bork mine and do a pretty damn good job of it.

Some kernels had broken UV interfaces that wouldn't undervolt the kernel and would allow you to undervolt by absurd amounts. (though it wasn't actually doing anything)

Well, are all the most popular kernels broken? Franco, glados, jame bond? I'm more inclined to think the problem is localized (either me or my phone).
And i'm running aokp 20, btw. Had 19 and milestone2 before those, which were all installed after full wipes (before anyone suggests that).

Your not the only one with this problem as I too have seen no change in battery performance on my gnex. I'm also using aokp 20 and Franco's (14.4). What I don't get however is that my buddy seems to see significant improvement in his phone while running the same rom/kernel combo
I've had some friends do some tests for me and run stock kernels for a while.
The differences in performance and battery life were menial between custom and stock.
What about all those people that claim seeing improved battery life? Not to mention those impresive screenshots of battery stats that show numbers i have yet to even come close to.

naturally. also, data calls are a huge battery drainer, even with excellent reception, when actually using the phone. the same with wifi.
to give the op an example, this last night i forgot wifi on. connected to my home network. the phone slept well (something woke it up in the middle but for a very short period of time, probably gmail), and i only lost 3%. i normally loose 1% in 7hrs approx., so it wasnt so bad.
on the other hand, if screenOn is true, it will obviously drain faster..

Tried a lot of combinations, but at the time of writing the original post i had been using aokp 20 with franco 14.4 for a while. I am currently trying aokp20 with trinity 384mhz gpu.
Also i lost about 2%/hour with franco in standby. I had mobile data connected and autosync only for google account + yahoo mail, all set to sync each hour.
Waiting on trinity now. Curious if i notice any difference besides the lack of franco's blueish tint.

My own or stock. I experiment a lot. Currently I am running a custom with a tweaked deadline scheduler, and a slightly different oc method for gpu and cpu than everyone is using to 1.35ghz. Stock voltages, tweaked ramdisk for filesystem mounts. Stock sleep profile of 350/700 on Interactive. Not using Setcpu to overclock at all. I set the power profile in fw-res to include the extra speed step.
So far so good, but its too early to tell. I went to bed and work up 9 hours off battery with 99% remaining. So its definitely deep sleeping fine I won't know for a couple days on whether it sucks battery dry or not.

exactly. I used to go crazy doing this and that, disabling this and that to try to get 20+ hours that people were getting on stock battery. Then I came to realize that the screenshots are probably mostly sleep time. Me being a very social person (text, IM, Facebook, and Tweet a lot) there is no way I was ever gonna get anywhere near 20 hours on stock. So I bought a couple of spare batteries, turned stuff back on, turn the screen back on brightly and enjoyed the phone and its great screen without worrying about battery life

Ill be as honest as I can. I just had two nexus and installed two different roms and and two different kernels....I believe they don't do anything as well..And I thinks its placebo effect when people are saying there battery's are better or the screen is smoother....I see not much of a difference even in stock...yes the benchmark may go up but that's means nothing really....

I've been experimenting with ROMs and kernels for the last 18 months, always looking for best battery life with regular to heavy use. A good custom kernel will sometimes give you an extra 10-15 %. Using setCPU or another app like systemtuner (my pref) to turn CPU down while screen off can also give you 5-10%. Far and away the best thing for my battery is to use an alternative launcher (ADW for me) and then use Titanium backup pro or systemtuner to freeze sense. you just find the two elements in the process list that start with "HTC sense" and freeze them. Night and day. FYI I run synergy and have always come back to Myn's ROMs cause they are good for battery from the start, but they also take well to pretty much any custom kernel, which isn't true for all ROMs. I like everything to work so I always ditch AOSP ROMs a few days after trying them.

Underclocking your CPU typically causes higher battery drain... unless you're overclocking. As long as nothing is really hammering the CPU in the background (which is the problem, not the CPU speed!), then it's better to let the CPU enter higher power states in order to finish the work quicker and return to low power sleep state. Intel calls this HUGI (Hurry Up and Get Idle). Overclocking can have bad effects with HUGI due to the higher voltage required to run at those frequencies. Lol'd at your AOSP comment though. I suppose some people are okay with subpar android, aka sense .
My Evo can last a week on a single charge. CM7.1, 1850 mAh aftermarket battery (slim, stock battery cover), Tiamat 4.1.0 kernel, aggressive undervolting and monitoring of wakelocks combined with 90% wifi usage (3g is the #1 source of battery drain!).

Underclocking is when you set the speed of the processor to a lower setting than the stock clocks where as undervolting is lowering the voltage needed to run it at a certain speed be it stock underclocked or overclocked. Simplest way I understand it.

Real culprit for batt issues
Has anyone ever bothered to understand that theres a pesty bug no one knew of.. Called CIQ "carrier IQ"
Ya this is one of the main reasons behind bad batt.. Sprint and other carriers allow a company to monitor and chart everything we do and it mirrors off txts and data sent and is designed to pick up on.key words... Basically an Invasive tracking monitor. It's a huge in noticed drain... And its been shown to be removed from system/app in many custom roms. But it never does cause its so strattled throughout the OS.

Bad battery life? Do some searching and read his kernel thread. Battery life has been amazing with his past releases. Build 7.1 are heavily exceptional builds.
Anything before that, yes the battery life hasn't been so good. But now his focus shifted onto the battery. Many people included screenshots of their battery graph.
Aokp also has a power saver mode, read into that as well

I did run AOKP build 12 for 1 day, and thats how long my battry lastet with nearly no usage at all. The same with eaglyblood all on latest fran kernel, with juicedefender ultimate on agressive setting.
So how can i test and post graphs for you?
What baseband are you on?
Is there any good taskiller i can use?
Dont know what is using so much battery except the screen and i have it on very low always.
I use stock 4.0.2, non rooted or unlocked bootoader, and I find the battery life better than most android phones i've used previously. However, occasionally, it gets low, then i plug it in, and later it's charged again!! As if by magic!! Also i noticed that if i turn it off completely, the battery life is aammmmaaaazzziinnngggg!!! *palms face*
sorry, these battery life threads really get my goat! On a serious note though, one nugget of knowedge that I have taken from messing with android for years is, that if you, like me in the past, have been one of these types that just cannot stop flashing roms left and right, then you will never get to see the full potential of your battery. It does depend of course more on individual usage than anything else, but, settling on a rom of choice and using it normally over the course of a week or so will see you gain an increase in capacity thereafter, just through simple calibration.
Im running AOKP v.13 with Franco's Kernel 9.2 and battery is really great, even on heavy usage. There's almost no batter drain in Sleep Mode (last night ~8 hours, the battery just dropped for 2%).
I've set up my syncs, set up AOKP's Powersave Mode to my wishes and made a ScreenOff Profile for franco's Kernel. That's all, and im still on my second battery loading cycle. Cant wait to see what will happen if it's callibrated well.
With AOKP Rom and its Powersave Mode, you dont even need Juice Defender anymore, its doing nearly the same.
Thank you, i will go back to AOKP in a few days and try build 13, i update you all
My battery holds 1 day 24hours, would say normal use with 2g on when screen of, 3g when screen on, i dont surf on it check facebook maybe 2 times on it, nothing more, text sms and few calls lasting maybe 40min total

How is your standby drain with that setup? 1% per hour? Or less?
I've used cm9 and aokp the past month and tried the stock Kernels that come with it and Franco's. One thing is for certain. No matter combination I get horrible battery life. If I run stock android with my extended battery including various Widgets I get 24 hours battery life pretty easily. Moderate usage and some heavy usage. With cm9 I'm getting maybe 15-16 hrs with aokp maybe 8-9 hers and I'm using Franco's kernel right now. I don't understand this. People talk about how much better the battery life is with various ROMS than stock but I'm not getting it. I'm getting like half the battery life I was before. Any ideas?

I can relate to you. Was in CM9 and Franko's kernel and as you said, horrible battery life. I went back to stock but this time I did not install apps thar would require services running (well I have to run WhatsApp so that's the only one running besides default abdroid services).
I am seeing better battery life this way.
The next step would be to install CM9 and restore all my apps to see if I can replicate the same battery life.

Well, this has pretty much nothing to do with the ROMs/kernels, you flash to the device. If you use the device for heavy gaming, you use loads of apps etc. the battery life will obviously be bad, because the CPU needs the according CPU clock speed...
Underclock the CPU, or better: Get AnTuTu CPU Master pro, and set the profiles, underclock screen off, to 700 MHz, and every other proile, where you do not neccessarily need the device to that speed, not below, otherwise it will just crash... That way you have the best battery life, for your usage, so basically, every time you switch the device's screen off, it will save a hell of a load of battery
Under clocking doesn't do much for battery life contrary to popular belief. It just increases the time it takes to process a task. It might take 1s at 1.2ghz vs 1.8s at 800ghz to complete a given task for example. So yes the cpu will run at lower speed and voltage but it still also take longer to return to idle.

Well, I don't really mean to break this, because it is right, but not completely...
Underclocking & undervolting, when the device is not in use (Screen off) saves loads of battery...
And because it's a dual-core, it takes mostly just as long to open an app at 700 MHz, as when you're doing it at stock clock speed, or voltage or higher.. So, in that case...

Screen on time was roughly an hour and a half! What is the BEST ROM with the best Kernel even, for battery life and extensive use of data?
The max I could get waas 2 hours screen on time, 3G really hurts your battery, I don'think theres anything that can change that
stock is always best.

No I don't think so. Are you using the Verizon or GSM version. There must be something with your phone or the settings, possibly a wake lock issue. With the GSM version and 2000mAh battery I can pull 3-4 hours of on screen time, using roms like AOKP and Franco Kernel. I turn off data, wifi, gps and bluetooth until I need them.
Can you go into Settings -> Battery an take a screenshot. Then press on the "battery graph" to reveal the history details screen and take another screenshot.
Not sure if it work with stock, but holding the Power + Volume down button should take a screenshot.
Every bodies phone acts different with certain ROM and kernel combinations I have had good luck with lean kernel but that doesn't neccassarily mean you will

For your display brightness, you may want to install Screen Filter. Its in the market. Especially without having to tinker with the display settings it lets you dim it down even lower than the lowest setting. Also great for movie viewing in a low/no light setting.
I think this requires root, but you should try Better Battery Stats, select partial wake locks since charged, and see what the culprit is.
CPU spy would also be a good one to see what frequencies your cpu is running on the most.
I'm currently on liquid beta 1. It seems to hold battery quite well compared to cm10. I also use trinity kernel, and the TKT app.

Don't 100% believe her, but wouldn't hurt to try.
I personally am loving AOKP Black Jelly Bean ROM The battery life is pretty average though
Using android revolution HD 6.0.1 stock kernel, stock battery, brightness @20% get 25hr battery life with 4hr screen on time.

I'll just go back to CM10 JellyBro Nightly KANG and hope for the best. I hear both the Trinity and Franco kernels are good for battery life. Anyone confirm this?

I used Franco for a good 4 months but now I switched and I like Trinity a lot more. The colors are so much netter on the screen. But its up to you, do some testing to see which u like better

DroidTh3ory's Patient Zero V3. He's not on XDA anymore, though, he has his own website at droidhive.com. Battery life and speed is always phenomenal on all his ROMs.

Lovin it
Very minimal battery drain, will test overnight

I've got my first android device just a bit longer than a week ago so I haven't had the chance to test a lot of ROM+kernel setups.
I flashed Jellybean for my gnex this last weekend, and I've noticed a severely precipitous drop in battery life (15% in 90 min, 15 min screen on). I found this yesterday when my phone went completely dead after just 6 hours on idle, despite running some pretty severe power-saving options. I can literally see the battery draining as I took the screenshots to post.
Running 4.1.1 stock, Franco Kernel Version 5 (power save powermode), 2100 mAh battery - I tried to provide as much information as I can in the screenshots. The weird thing is that none of the information stands out as an obvious power-drain, its just falling for what I believe to be no good reason.
Please help!
First of all: congrats if providing such detailed information about your battery information! (I'm being serious, not sarcastic)
Secondly, have you tried running it with WiFi only to see if there's a difference? Also, you need to go through about 2-3 charge cycles before you have a good idea of our battery range.
Also, what kernel are you using?

I have same problem, 1750 stock battery only lasts about 3 hours....
AOKP JB B 1 and franco

Kernel
I'm hoping its just running it a few charge cycles fixes the problem, because my battery meter is like a countdown clock right now.
I'm running 3.0.41-franco.Kernel-Milestone5.

I reccommend getting cpu sleeper. Its brillant and saves me tons of battery

CPU Sleep
Thanks! However, I'm already running on only one core, from a setting in Franco's app.
My problem is that there doesn't seem to be anything glaring that is draining my battery. Awake time is slightly more than I'd like, but not nearly enough to drain the battery at 10% an hour with the screen off.
And for the above poster, I have not tried running it with wifi only and no mobile data - wifi at my office is spotty, and I'd like the conditions I am testing it at to try to mirror how I would normally use my phone.

hmmm... did u try replacing the battery?
Battery
No - the battery worked just fine on ICS as of last Friday (28 hours standby charge). I would hope that flashing ROMs/Kernels would not actually damage it.
Thanks for trying to help - I'm really confused since all the ratios look comparable to people who get great battery life, but for some reason, just seem to suck about 5x more battery for me, so its impossible to pinpoint one specific culprit. I thought it was a mis-calibration, but apparently that is just a myth.

Let me start by saying that I am not an expert, but the following tips helped me. I agree with the WiFi and the detail you provided was great. I see that you are running 4G, this will eat up the battery. Your ROM may have a toggle for the 4G (LTE) and 3G (CDMA). If you have WiFi available I would use that. You may want to turn off the NFC (system setting>Wireless & Networks More....) unless you use google wallet or share screen alot. Also, I had horrible results with the Facebook app running in the background, which I have taken off my phone. I set a bookmark in dolphin browser instead of using the app.
If you are not seeing any improvements with in the next few battery cycles you may try wiping the battery stats in Recovery. The first ROM I flashed from stock my battery life was all over the map and wiping battery stats helped. I ran the same Franco Kernel and was getting 2.5 -3 hrs of screen time. Hope this helps.
also, get CpuSpy from the market, and see which speeds your cpu is using (or not using).
Not that this will help software issues but Sprint is giving away a free 2100Mah extended battery with the door. You just have to pay for the shipping. No scam at all, I think they know that they have a glitchy piece of product and need to help calm us down. Just call telesales and tell them you own a Gnex.
CPU Speeds
Almost exclusively at 384 or 729 mHz, capped at 1026.

So that means that the CPU isn't going into deep sleep, which is an issue.
All I can suggest is reflash with a full wipe, and reinstall the apps you can, and slowly weed out any rogue apps that could be causing said issue.

Deep Sleep
Sorry, I meant that when awake, the vast majority of the clock speeds are 384 and 729. I am in deep sleep approximately 75% of the time.
If no solution comes up in this thread, I will try re-flashing to stock JB/stock JB kernel tomorrow night to see if it just needed a few recharge cycles to stabilize, and if not, if wiping/reinstalling helps.

I'm getting the complete opposite of u op
Sent from my Galaxy Nexus using xda premium
Yeah, that seems to be the general experience here. My phone is down to ~28% since the OP. Again, the proportions in which things are draining power are correct, they are just doing it too quickly (1% per minute of screen time).
I'm going to completely wipe and re-flash JB tonight, keeping the stock kernel this time, unless someone can help me out.

Did u flash francos kernel yet ?
Sent from my Galaxy Nexus using xda premium
Yes - every process/screen is drawing the typical percentage of power use (~50% screen, 8% Phone Idle, 8% cell standby), but the battery is draining 4x faster than it should. Francos app shows me running at completely standard voltage, and I'm on the powersave mode. I think it must be a battery indicator/stats issue, otherwise the proportions would be all off.

Try wiping ur battery stats in cwm

I know that is supposedly a placebo, but in this case, something is clearly wrong. I'll give it a try.
