Jelly Bean Battery Life

So obviously Jelly Bean so far has been a battery hog, I'm coming from AOKP. So what's the best kernel for battery life? Or what's the best ROM / Kernel combination? The opinions I'm looking for are from people with real world experiences, and that have tested all of the kernels available.
Thanks

leave everything stock for best battery life

IMO people think the battery life sucks because they're always on their phone. Atleast that's how I am, but however I'm on Vicious 4.1.1 V1 and I'm getting incredible battery life with the kernel that comes w/ it.

Another one of these threads.....

Do any custom ROMs have the same or better idle battery life?

I've tried CM9 and CM10 roms, but the idle for all of them is much worse than stock Kindle rom. I'm using Modaco custom Kindle rom, which is just as good (if not better) battery than pure stock, but I'm wondering if there's a non-Kindle looking rom (ICS or JB) that doesn't have poor battery life.
Thanks!

Nope... use cm7 it has excellent battery life ics and jelly bean will probably always suck like pigs when it comes to battery life..

That's a shame. Do you know why? Kernel issue I'm guessing?
My Galaxy Nexus is getting great battery with a custom kernel (Franco's), so it seems like other devices should be able to get good life with the right kernel. I wonder what's causing so much idle battery drain on the ICS/JB kernels.
Thanks for the info though! I might stick with Modaco since it opens up the market yet retains the good battery life.

Rom Question

Hey, im just wondering what rom has the best battery life? Im tired of having to have to worry about my phone dying 5 hours into the day, if that. i dont use any apps that are battery heavy, at least i dont think, just instagram twitter and messaging

Unfortunately, the best answer you're going to get are based of the devices performance which is individual. Sure, there are over all battery performance roms..
Sounds like you may have a defective battery if that is all you're getting.
My suggestion, if you're stock, invest in a new battery. Or if nothing else, take your current battery to the a Sprint store and have them replace it.
I would honestly run a stock build to test the battery life. Fi03 is giving people 3-5 hours on screen time...

Right now im running the JB Aosp and its dying so fast, back when i was running stock ics is was okay battery, 5 hours during school and it was at 20%. I think im just going to flash down to gingerbread because i had the best battery life then. I guess ill have to give up the features of Ics and Jelly Bean

Ah, well then you are definitely not alone in regards to battery life. Some are seeing great life, and others, like you, are seeing abysmal life.
Before you go all the way back to GB, why not try the Fi03 leak?

http://forum.xda-developers.com/showthread.php?t=1705569 Try this one... I have decent life.. Screen dim to lower setting, juice defender managing data, Sync time for data (email and stuff) set to longer durations.. currently 3 hrs 21 min, 89% battery life.

Am I the only one still using GB???

I have found that out of all the ROM's Ive tried, even the latest JB ones, that the ones with the best battery life and stability were Blazer and Calks 3.0. Those of which are on Gingerbread. So, am I the only one that thinks or agrees to this? I might not be "up to date" but my performance is damn good! =)

must be
What little extra battery life I'm not getting on FK23 & FL16 compared to GB is not worth all the extra goodies I would have to live without. For me GB is boring and the tradeoff is more than worth it.
Have you tried both the TW JB and the AOSP JB roms?

Haha, you're not the only one. After DD'ing Jellybean leaks for the past 25 days, I flashed back to my Calkulin nandroid backup for its awesome battery life. . I got the best Jellybean battery life on fl16 (3 hrs 45 mins) but it can't compare to the ~6 hrs on calkulin. I'm just gonna wait now for the ota Jellybean + source before I try it again.

Probably not the 'only' one. But in these parts XDA Developers you will certainly be in the minority.
By it's very nature these forums are for those looking for the latest greatest and bleeding edge technologies and tweaks.
The latest JB builds are awesome. Good battery, hotspot working natively (so far). Stable. Google Now natively. More responsiveness. Nicer looking and more customizable. I get about 14+ hours with fairyly heavy usage - my cell is my phone for work and home.
Yes these forums do provide some great stuff for the 'regular joe' but that's not what the forums are here for. We try to work together to get the most out of the devices as possible. That usually means functionalily and features 1st, performance 2nd and battery 3rd. I do know that there are some devs who may change those orders but that is usually the case.
I have always been amused by the 'how long does your battery last' crowd. While I think any phone should last at least a day with a good battery and reasonable usage I think it's silly to 'demand' more. It's 2012 get another battery (or external battery for emergencies) for backup, grab more chargers - I have one in all cars, home office work office and laptop bags.
Just my two cents.

Have you tried replacing your battery ? I just bought 2 new ones from Anker and my phone is getting better battery life and I'm running FL16 JB. I am delighted with the purchase and wish I had done it sooner. Here's link and read up on them as well.

Good luck

Personally I use CM10 on my phone, but on my mate's phone, it's running Blazer's 4.1 GB sheerly because of the WiMax speeds. If I didn't love flashing the latest and greatest, I would've stuck with GB too.

From my experience, nothing beats calkulin's 2.8.1. I wanted to like more current roms, but even with underclocking, ics and jb chug the battery. People can ask or claim that your battery is bad. If the battery is bad then why can I get about double the battery life out of calkulin when compared to more recent roms? Same battery, twice the run time, practically no lag or noticeable performance hit. I was halfway through my second extended life battery during a normal shift at work with ics and jb when going home when I'd be around 20% with calkulin gb on the first battery. I'm not saying everyone else is wrong in their preferences, but to me, battery efficiency without noticeable CPU hit means everything. Other builds seem sluggish and battery hogs to me. Don't get me wrong, there's some cool features with new builds but the trade off of battery isn't worth it to me. It's a damned shame calkulin moved onto other pastures. He definitely knew his $hit when it came to tweaking rooms and I like his choices he took in his earlier builds with this phone.
I think if calkulin and bugless beast Pete got together, their rom would be damned near bulletproof. Peter Alfonzo.

Pacman ROM has amazing battery life for being JB. Plenty of customization tweaks as well, I used to only rock blazer 4.1 as well but some of my apps got updated and now require to be on ICS or JB based ROM.

Current best known setup for battery life?

Currently I am on HO!NO!'s Full Throttle V9 (CM9 base) with a slight undervolt, an OC at 1.78Ghz, brightness on lowest, and LTE off. There is not a huge difference in battery life between HSPA+ and EDGE. The idle battery drain is about ~1%/hour which is pretty fair.
I've heard some people say they've gotten very good results on CM10.1 with Wind Kernel and I was was hoping that people could share what their setup is as far as achieving the battery life I've read about in some ROM threads. I feel outdated rocking CM9, when CM10.1 has alot of nice features I'd like to get in on.

imo the rom in my sig, but i haven't tested every one

for battery?
ICS: Liquid Nitro and HO!NO!'s v20f are probably the best, then HO!NO! CM9.
JB: I have no idea! Right now I'm running CM10.1M2+Wind, but it still drains too fast when in use, especially while using data/wifi, but it's getting better with incremental versions. I didn't have much luck with the CM10 variants I tried, but I might go back and try Quattrimus again.

Looks like my suspicions are confirmed so far, that no JB ROM can touch ICS as far as battery life goes. I have no clue why this is, although I know that 4.2.2 is much better than 4.1. However, as big of an improvement as 4.2.2 is over 4.1, it still doesn't come close to ICS battery life.

Screen off I can get 4.2.2 sleeping like a baby.
It's when the screen is on and data is being transferred that it becomes a bit of a hog.
Even so, I can usually get through a day of use without charging.
