Slightly worse, enough to notice, not enough to be a deal breaker. There's no guilty party evident in my battery history, or in BBS. I'm leaning toward weaker wifi at this point, next step is to compare my battery on data to what I expected on ICS. There has been much funky wifi activity for me the past several iterations of the wifi drivers. I'm lucky (or unlucky) enough to be around an accessible router 90% of the time and relied on that to get extremely good battery life on GB and ICS.
[Samsung Galaxy Nexus] ÜBER™:
Same here... I'm gun a try 3G all day tomorrow and see how it compares. I noticed jelly bean made my WiFi speeds normal and that I have much netter signal in my room. Where I was getting only around 16 Mbps I'm now getting my expected 30mbps.

I'm definitely gonna try turning off Google now and location services and see if there is a big difference.
[Samsung Galaxy Nexus] gogol:
Here is mine on stock JB 4.1.1.

32 hours stand by with 4 hours screen on time.

I think, it is not that bad.

Brightness is set to 15% most of the time, or AUTO when I am outside.

All sync off.

I played 5 levels of Xelorians.

Loads of web browsing, Facebook, G+.

Few checks on Y! mail and Gmail.

On ICS, I could get about 2 days in total, with around 3 and a half screen on time.
[Samsung Galaxy Nexus] splus:
My battery life on JB is also worse than on ICS. I tried only 3G or only WiFi but battery simply drains faster than on ICS.

I'm actually finding that phone sleeps better than on ICS, but battery drains faster when I'm using my phone. I've tried to compare with typical usage, same CPU clock, with few different apps, and in every case the battery goes down faster than it did on ICS.
[Samsung Galaxy Nexus] moe6:
1) Uncheck location history. Sign out of Latitude. Leave the top one as is. The important ones for Google Now is actually in Settings>Location Settings. Not that Latitude doesn't help Google Now but it's not required as it can, in my testing, get most if not all it's info just by the regular Location Settings (Google Location).

2) Leave wifi alwayson, it uses less battery. It goes into a low power Wifi state when the screen is off and your router is much closer to you than a cell tower will be :P. It also saves some battery if you use Google Now as it'll get location data from wifi AP names around you also instead of using GPS (more battery) and/or reduce it finding your position by cell towers.
[Samsung Galaxy Nexus] lorin_93:
Good.

That's definitely a good time. To be honest, I'm impressed by the battery life on stock JB Roms.
[Samsung Galaxy Nexus] Skurvy_Pirate:
I feel like they are about the same, maybe a little less on JB. But considering all the extra stuff JB is doing (Butter, Now) I am suprised it is holding up as well. I run with pretty much everything on because I need constant email syncing and am usually next to a charger.
[Samsung Galaxy Nexus] EP2008:
Using "Battery Monitor Widget" (rather than guessing), I can see jelly bean consuming about twice as much as ICS. Disappointing to say the least.
[Samsung Galaxy Nexus] jzero88:
Really? That's interesting. I'm going to load that up right now too. Do you know what is running more or killing the battery more?
[Samsung Galaxy Nexus] danimar1:
For me it's around 25% worse with JB (stock), no new apps installed since ICS or different usage patterns, so it has to be the OS... It's a shame because it looks even better than ICS
[Samsung Galaxy Nexus] Liquid_Cool:
Running vicious jb and have had no difference in battery life. I'm using faux kernel and everything has been smooth for me so far. Loaded rom from stock ics. Tc
[Samsung Galaxy Nexus] martindesu:
I'm finding JB to be more of a battery drainer due to Google Now I assume. With ICS I was getting insane battery life. I still easily make it through a day, but I imagine that Google Now syncing and location updates are sapping juice.
[Samsung Galaxy Nexus] msavic6:
First day with jellybean, auto brightness and wifi pretty much the whole time.
[Samsung Galaxy Nexus] NerdFurgison:
Aokp and air kernel giving me excellent battery life (jb)
[Samsung Galaxy Nexus] jzero88:
Went back to Stock ICS, all stock except rooted and busybox. Ya, THIS IS HARD. Can't believe how laggy this is?

Ya we are running a bunch of VM, and that is the root of all the problems. Too bad android wasn't built another way?

Will try ICS again, might add Trinity kernel since I bought the app :) we will see how long I can last and see how the battery holds up.
[Samsung Galaxy Nexus] Kookas:
Battery life is as good on JB as on ICS. And by that I mean it sucks, dead in 3-4 hours of screen time. I carry around an external battery for it when I will be using it extensively.

By the way, I've been using the Pebble 5000mAh external battery which is pretty good. Upgrading to a PowerGen 8000mAh soon, though.

[Samsung Galaxy Nexus] bgdxv:
8000 mAh ?? damn, can you carry that thing in a pocket or you need a backpack?
[Samsung Galaxy Nexus] Kookas:
Haha, it's only supposed to be the size of a pack of cards though so it isn't that bad. This is what happens when OEMs obsess over making their phones too thin.

[Samsung Galaxy Nexus] CMNein:
Ironically my JB battery life miraculously started equaling that of ICS a few days ago. Nothing "changed", except a new nightly, but I've yet to find any commits that would have directly affected it. No settings changed at that point.

Got a further boost when autobacklight levels were cherry picked so I could apply my custom screen levels.

Back to 0.25% drain/hour while on wifi through the night and ~4min screen on time per % while I'm doing my average thing(s).
[Samsung Galaxy Nexus] jzero88:
Wow that's nice percentages. What's your setup?
[Samsung Galaxy Nexus] CMNein:
Euroskank CM10 + Trinity 35 384-1190, G+, + gmail + exchange accts (1 native app, 1 Moxier) checking at 1/2 hour intervals. Sync on from 08:00 to 15:00 daily. Wifi helps tremendously. I do have Google Now enabled, but not location based services. I was just thinking yesterday that it would be nice to have the option to set a static location in Google Now.

Sitting at 1 hour display and a few hundred MB of DL over 21 hours (9 hours of that time I was sleeping) and at 77% battery right now. For MY use, this is good, albeit "light weekend use". All I'm really concerned about is having minimal drain with screen off. Similar to what I saw on ICS.
[Samsung Galaxy Nexus] numb_:
With JellyBean I have an amazing batt life! With ICS only 2 ½ hours of screen on, but now i reached this wonderful results! :victory:

Always with 3g or wifi..
[Samsung Galaxy Nexus] msavic6:
Over the past week I've been using jellybean and my battery life is a lot better. Having 3G on, auto brightness and gmail syncing I can get 3 hours screen a on time and 16-19 hours standby. When I'm only on wifi and auto brightness and gmail syncing I can get 4 hours screen on time, if I was too lower my brightness I could maybe get 4:30 screen on time. I'm on stock 4.1.1 with unlocked boot loader.
[Samsung Galaxy Nexus] DualDark:
For me is so far the same battery life.. I think it most depends on which apps you had installed.

[Samsung Galaxy Nexus] androo45:
This is it. I'm done. I'm back on ICS 4.0.4 (Rascream + Franco kernel)

I have tried many JB roms; stock, bigxie, jellybelly, CM, AOKP, XenonHD, ... with different kernels, etc. Every time I have good batterylife on wifi, but terrible on 3g. It drains at 8 to 9%/h. All the google now stuff is of, no excessive wakelocks.

At the end of the day I have 1h20min screen on and a dead battery (2000mAh)

Back on ICS I get 3,5h screen on at the end of the day (on 3g) and a couple days of standby with very light use.

Google you messed this up bigtime!

This thread is depressing me lol....

I think I need to warranty my battery, I have never hit 3 hours of screen-on time yet...

That was me before. On 4.0.1 I could barely hit 3 hours now its quite easy.

[Samsung Galaxy Nexus] tekkdrone:
Subjectively, it seems shorter. CDMA/LTE/VZW, AOSP 4.1.1

I'm still collecting data on mine, as my usage has been abnormal from ROM testing. Battery usage while idle seems normal. Battery usage while using seems to have increased by at least 15-20%. (Rough guess)

My wife's gnex seems to display roughly the same delta in battery consumption, and her usage patterns have been pretty consistent since I flashed her device.
[Samsung Galaxy Nexus] maliceomalice:
I got a gsm nexus on JB. My battery life ia kinda great i think coz i never have experience with ICS (just bought it). I got 4 hours+ on screen time with 3g 90% of all the time...

[Samsung Galaxy Nexus] Neo3D:
Installed CNA Jelly Bean 4.1.1 on my gf's Verizon Galaxy Nexus and battery life took a very severe hit. She went for 2.5hrs screen time to <1hr.

However, I installed the same ROM on my Sprint Nexus S and battery life is noticeably better than when I was running ICS on it. It's MUCH smoother as well!

The difference is that we were running Franco on her phone. So, I replaced it with Trinity. If that doesn't help, I'm going back to the stock kernel.

You must have the GSM model. I never seen the LTE model with such high screen on time.
[Samsung Galaxy Nexus] Neo3D:
This is depressing.

For the past 3 days, we've tried 3 different kernels:

Franco

Trinity

Stock kernel on CNA JB ROM

None of them will run her phone for more than 4-5hrs. She used to get triple that runtime before.

It's frustrating beyond belief. The phone is able to go into DEEP SLEEP:

The phone was unplugged probably around 7:30am this morning.

Any ideas? Anyone else getting this?

I'm at a loss, it's not a wake lock issue.

From ICS to JB I went down from around 4hrs screen on time to 2.5.

Standby time also decreased considerably.

Ander Settings -> Battery "Android OS" used to have only 5 minutes keep awake time during my average 8hrs of sleep time. Now it's around 45 minutes keep awake.

I am on the Verizon "Unofficial" 4.1.1 that released about 3 weeks ago. My battery life is worse then ICS, but.......I have alot more stuff turned on with JB then I did with ICS. I have been messing around a lot with Google now and everything it has to offer......which is a huge battery drain. All the sync services and location services that it needs on is probably what is draining my battery. I have around 400+ wakelocks just from Google maps each day.....but I know what that is from.....location history. I haven't bothered to turn it off just yet.

On ICS I was getting around 17 hours a day with 2-3+ hours of screen time, 2+ hours of phone calls.....no wifi just 3G/4G. Now on JB I am lucky if I make it to 15 hours with 2 hours of screen time and under 30 minutes of phone calls. I did notice that radios are a lot stronger in JB, but that also hurts the battery life. I am on 4G more now then I ever was with ICS, and on phone calls now I am almost constantly on 4G.....the drawback though is it eats the battery big time!!!

I am happy now with my setup, but I know I can turn off stuff to get more battery life. I did a dirty flash at first, and I was getting horrible battery life with JB......like 7 hours with doing nothing, just letting it sit there. I did a wipe and a clean install and now I am at the 12-15ish hours depending on use. I can live with that.
[Samsung Galaxy Nexus] Fire n mage:
I feel like I made a mistake after not running stock when i received the phone, I always feel like my battery was subpar compared to my epic 4g, maybe I'll hit up the stock JB ROM.
[Samsung Galaxy Nexus] Ratlegion:
Guys, normally I don't say much on XDA, but my wife's Nexus has always had horrid battery life since we got it. I'd been following the thread before I got Jelly Bean installed on her phone, because she prefers stock. I only rooted it so I could used Titanium Backup for her. I'm doing the first run down on the calibration, and at 4 percent battery left, I have18 hours, 19 minutes, with 3 hours and 12 minutes of screen time. The screen has used 72 percent of the battery, 65 percent of which was set for 100%. All syncing was left on. In the past, she would struggle to get through 12 hours on AIRPLANE MODE. All I did was sign out of Latitude, and turn off location history. I think Jelly Bean looks to be a lot more promising than ICS was, and she has always been stock.
[Samsung Galaxy Nexus] :
This is my personal opinion from galaxy nexus paranoid android jb using franco milestone 5, the main difference between the two is one, project butter imho don't consume anything, or drain less than ics for simple reason about gpu and cpu governor, now is better management

The battery drain causes is 4

Display ,always use auto brightness and u are ok?

Apps too apps with auto sync induce a little sleep time for a phone, more battery

Kernel and governor, use cpu speed for what you want do, 1200 mhz is enough sufficient for anything, over clock consume more battery only, 1000 mhz is good for anything except 3d game I use

Interactive 300mhz-1000mhz now I'm 65 with 16 hours unplugged 3 hours screen on, 3g wireless always on with juice defender tasks best governor I see modded is interactive from fugukernel, smooth like good, using only 172mhz and 300 mhz, 1-5% max speed only, franco too but franco use 700 mhz instead 300, it's not good, my device's smart reflex using same power for 700 and 1000, it's not good for me

Brain, use brain is useless using 3g when u are under wireless, 2g consume less, same thing for data, is useless using 3g 4G connection only for what's app stay with 2g is better, what's app working too

Today's usage. Don't be fooled by the WiFi showing as on. I was on 3G from 11am till 5:30pm and completely forgot to turn WiFi off when I left for work. I actually would've figured forgetting WiFi on would have impacted battery more considering it scans at intervals looking for networks.
