All,
One thing I noticed in reading these posts and seeing people's device information in their signature is that there are a few versions of the radio that people are running. Some have stayed on an older version, while others have upgraded to newer versions.
I am wondering if a particular version gives us the best overall coverage and battery life. I would appreciate it if you could respond with the version you are running. I would like to compile the responses and see which versions people are running. I am then going to test each version for a couple of days and see the implications of each version on battery life.
Thanks,
Steve
radio can influence battery. it all comes back to your dbms reading, the lower the better. try a few of the radios and see what happens.
9.01 now. Ran 7.28,4.08 and 5.06 before though. 4.08 wasn't bad.

This discussion is all over the place but a dedicated thread with battery results is good. we need to post our location as well as screen shots. im on long island and 04.08 does well with data speeds. im in a building heavily protected meaning they do well blocking reception and i am able to pull 3g in 99% of the time with an occasional drop to 1x.
I just flashed 09.01 from 04.08 and went from -84 dbm to -80 dbm sitting in the same spot.

From my experience the radio has a lot to do with battery life. The radio effects how your phone communicates with the local towers. The difference between radios are tweaks within the voltages. Your best best is to try them all and see which one gives you the best happy medium between reception, call quality, data speeds and battery life. I personally get slightly fast data speeds with the newer 4.08 and 5.06, however I did notice that my battery was draining faster while using data, so I went back to 9.01 which seemed like the happy medium for me. Just because 9.01 works well for me, doesn't mean that others will have similar results. Just like how the same type of phone can act differently with kernel voltage changes, the same goes for radios.
Remember when testing different radios to rule out any variables that may change your results. An example of this is when I was testing out the newest radio, I updated Dolphin HD also. After doing so, I ran into an issue with web pages stop loading half way. I originally blamed the radio for this, but then remembered that I had also update the browser. It turned out that the newest update had some bugs and this was one of them.
Hello everyone.
So I bought this phone this past Friday and been having a blast with it. I bought the 2100mah verizon/samsung extended battery yesterday to have a bit better battery life with it. I have patience with battery life, so I'm ready to try anything.
Here's part 1 of my post (radio): So I'm on 4.0.4. I have the radio that comes with it. I noticed I can only get 1-2 bars (rarely 3) of signal at times. I read that the best way to post about this is in dBm so here are mines: -100 to -120 80% of the time. This is on 3g/4g/wifi. And it's rarely on 4g, it is always jumping to 3g. My mom has a thunderbolt and to test, I saw the thunderbolt had better dBm and always had a 4g signal, 3-4 bars constant, rarely 3g. I'm in Miami, Florida if it matters, which is a strong 4g area. When it's on 3g it gets very good signal, 3-4 bars and -80 dBm. Though sometimes I noticed my wi-fi gets 4 bars for like 10 minutes and returns back to 2 bars.
Anything I can do as far as the Radio, some people have fixed it with a new sim card but before I go get one (are they free?) let's see what I can try? Perphaps a new radio?
Part 2: Alright now as for the battery life. Here are my phone "stats": (screenshots are posted at the bottom of post for battery)
-4.0.4 Stock ROM nothing changed, just an unlocked bootloader.
-WiFi on when at home, off when using 3g/4g.
-NFC On.
-No syncing, everything updates when I open app (twitter, weather)
-Gmail is set to push, atleast I think so. It notifies me of a new email every time.
-48% Screen Brightness
-Signed OFF from Google+
That's it I believe, if anything else is needed let me know.
I have the XDA version of BetteryBatteryStats, so I guess I have the tool to fix it just need to pinpoint what the problem is. I'm draining at 2%-3% per hour with wi-fi, and no usage, just idle. Again this is with 4.0.4 update. I'm seeing people's battery life becoming awesome with some tweaking, so would like assistance on that.
Here are my screenshots:
Day 1 with ext battery on 4.0.4:
Day 2 with ext battery on 4.0.4:
Have you confirmed that you have the new radios installed?
I515.09 V.FA02 / I515.FA02 (or could show as I515.10 V.FA02 / I515.FA02)
You probably did that, but just wanted to be sure.
I have: I515.09 V.FA02 / I5I5.FA02
I appreciate the help!
How far off are you on strength from the T-Bolt? I think it's the 4.0.4 radios and I'll get into why I think that. Note that the following isn't scientific and I haven't really tested it, so don't spread this like it's fact. I live in a really strong 4G area, so in general I haven't noticed a difference with any of the various modems (I've tried them all). I will say that I worked for a week once in an area with poor Verizon coverage, and I noticed that the 4.0.2 radios worked better for me than the 4.0.3. Like, no coverage with 4.0.3 after upgrading to it, so I whipped my laptop out and pushed the 4.0.2 radios and got from zero bars w/ coverage to 1 bar. I don't know how the 4.0.2 radios compare to 4.0.4, but you might give that a whirl.
In general, I think that radio hype is just that, hype, and there's a reason why a slew of radios never make the final cut, but with Verizon trying to patch 3G/4G connectivity, I do think it's worth trying some other radio's out to see what they do in your area.
I hesitate to say the following because I have NOT paid that much attention or done significant testing on our radios, which is something I've done with previous devices. So do NOT take this as gospel, rather with a healthy dose of salt.
In my limited observation with 4.0.4, at least in my neighborhood/area of Birmingham (I have an LTE tower practically in my back yard), the 4.0.4 radios ARE weaker. With 4.0.2 radios for example, I want to say I got -70dBm on CDMA/1X in the house and usually -72dBm to -75dBm on LTE in the house. Right now, typing this thread on 4.0.4 with the phone showing 5 bars, I just checked my strength on LTE and it was registering -94dBm here at the house when I rolled onto CDMA, it showed -75dBm. When I rolled back onto LTE, it showed -75dBm (displaying 5 bars the entire time) then went to -87dBm a few minutes later. This is with the phone sitting on it's normal spot on my desk.
Random, first thoughts with 4.0.4:
1) We know that Verizon requested "updated" display bars for 4.0.4
2) There could be an issue in 4.0.4 with dBm updating/display. I haven't been at the house all day, I have roamed around, but I doubt very seriously that my real signal strength on LTE was really -94dBm here at home. When I say I have an LTE tower in my backyard, I'm literally talking about 1/4 of a mile away, on top of a hill.
3) 4.0.4 is not always registering/reading signal strength correctly, which is causing devices in a weak area to fall off of 4G and onto 3G when the issue isn't really with the tower, physical hardware, or the modem package, but on the way 4.0.4 is interpreting the signal information it's pulling in (based SOLELY on watching the signal range I just observed on LTE). That said, it easily could just be the tower this afternoon. AGAIN, take it all with a grain of salt.
I recommend trying the 4.0.2 radios, at a minimum. I would list them, but I don't know our radios off the top of my head yet (too much Vibrant info is still in my brain). Search for them, they're easy to find. BE SURE to push the CDMA/LTE radios paired together. Like, the 4.0.2 radios together, 4.0.3 radios together. Do NOT mix and match.
Generally speaking for people in good LTE areas, I think the 4.0.4 radio package is GREAT. I've noticed zero slow down. Yeah, -87dBm (which is what I normally see here at the house) IS "weak" and it SUCKS to have wrong bars displayed but I haven't noticed any slow down on the network. I think slightly scaling down LTE strength is what has helped improve battery life. CDMA radio strength does not appear to have been affected, which is what you're gonna be on in rural areas anyway so unless you're on the fringe of LTE signal like the OP, I don't think this radio package is anything to complain or be worried about.

Also, in my experience as someone that travels all over for work, the only time that "weak" signal drains battery is when you're on the fringe of no connection and the OS is boosting power to the cell antenna's. On the old/real signal indicator, this was when you had a connection to Verizon with 0 bars and it was boosting you to 1 bar. I'm not comfortable stating a -dBm range because I can't remember what I observed and I didn't write it down. If you already have 1 or 2 bars (again, on the "old" signal indicator) you really don't see a boost given to the radios. By "boost", I mean you can click on the battery graph and see where signal strength went up and battery consumption did too, while your phone sat in the same place. I have a screen shot of this that I will try to find, and update this post with.
Looking at your screen shots, I don't see that affect. In general terms, your battery life looks "fine" "normal", whatever we want to call it. Bear in mind that our LTE GNex's don't get the same life as our GSM counterparts.
Edit:
Found the screen shot I was talking about. This was on stock 4.0.2 in my hotel room one night in a rural area. The night before I had data/sync on and noticed that when I woke up my battery was about dead. I knew it was due to signal strength since I was used to losing about 8% over night. So the following night I turned off data/sync and let it run over night, not wasting the opportunity to watch what would happen to battery life with and extra boost to the radio to get improved signal strength along with removing app/data activity from the battery consumption mix by keeping data/sync off. If I remember correctly, I went to bed @ 100% and woke up 7 hours 44 minutes later with something like 72% battery. Not only did the phone boost the power to the cellular antenna, but this activity also kept the phone from sleeping properly. I'm GLAD smart phone's can do this, but at a minimum, it turned a roughly 8% battery drain over X period of time into a 28% battery drain.
I hope my info/experiences haven't confused things further for you.
CDMA Input
So what have others found about CDMA battery life?? Mine is poor no matter what ROM or Kernel I seem to try to run. I also have attempted under voltages in SetCPU to see if that helps. Any feedback is greatly appreciated. Peace.

You need to define "poor". Everyone's use is different as are their apps. If you truly have poor battery life no matter what, look at the three things that are always probably the same. 1) Your physical battery. Is it defective? 2) The apps you use. Perhaps you have an app that is acting up and syncing like crazy or wasting CPU cycles. 3) The area you live in. Do you have poor signal strength?
The biggest drain on your battery is ALWAYS going to be your screen, and data/sync. In my personal use, my biggest drain is: Screen Brightness 100%, Netflix running, Audio 100% through the speaker. This equals about 30% per hour with the Verizon Extended Battery depending on what all else syncs in the background...with a live wallpaper.
Undervolting is a misleading thing. People will disagree with me, but when you look at power consumption tables, undervolting does very little. When our phones display battery % remaining, it's not based on the actual juice left in the battery. It's a calculation based on charts that the phone manufacturer (probably Google in our case) took from the hardware manufacturer and put into play that basically says that at this Processor Speed (X), this Level of Power Consumption Occurred (Y). It happened for this Amount of Time (Z) and then it compiles that data and solves for an amount of power used giving us a percentage of remaining battery life. In general, this is VERY accurate. However, there are no values programed in to account for undervolting...or OVER clocking for that matter. For example, if you're overclocked to 1350MHz, then Android is going to use the values for 1200MHz. If you put a timer on your battery life, you'll see a longer run if you run your phone until it shuts itself off. But it's not THAT big of a difference. All the while when your watching how quickly your battery bar drops with your use, you can't see a a measurable difference.
In my experience with undervolting, doing so got me maybe an extra 5% boost in battery life. I can't equate that to a time because again, usage is different. In general, a 5% swing in a charge cycle can be easily accounted for by other things. Does your processor use more juice @ 1200MHz with normal volting compared to 1200MHz undervolted? Absolutely, but undervolting isn't going to get someone hours of extra battery life, especially when our screens usually account for 60%+ of our battery consumption. All said and done, undervolting results in gaining us very few percentage points in terms of what percentage of battery life our processors consumed.
Seems like the kernel and rom do make some difference not just apps. I use AutoStarts to prevent a mess of them starting upon boot. I am sure the screen takes a ton of it. But I am convinced that it depends on voltages and kernels too. Since I notice differences.
I recommend trying the 4.0.2 radios, at a minimum. I would list them, but I don't know our radios off the top of my head yet (too much Vibrant info is still in my brain). Search for them, they're easy to find. BE SURE to push the CDMA/LTE radios paired together. Like, the 4.0.2 radios together, 4.0.3 radios together. Do NOT mix and match.
Generally speaking for people in good LTE areas, I think the 4.0.4 radio package is GREAT. I've noticed zero slow down. Yeah, -87dBm (which is what I normally see here at the house) IS "weak" and it SUCKS to have wrong bars displayed but I haven't noticed any slow down on the network.

Ok KWK, but there's a trade off here. If I try the 4.0.2 radios, that some people reported bad battery life on, it's just because it had a bad trade off for SOME
people right? So that means 4.0.2 radios could be good for me and result in better battery? Can I be on 4.0.4 and have the 4.0.2 radios?
Anyone know where to find these 4.0.2 radios and how to flash?
As for the battery life part of my post, what do you guys think I should try doing in betterbatterystats? A recent thread on here: http://forum.xda-developers.com/showthread.php?t=1483829&page=3 (Go to page 3 and last post) He got his life fixed. So that's nice to know there's tweaks that can be done. Any suggestions? Look at the http://forum.xda-developers.com/showthread.php?t=1488680&page=6 thread too. "draining at 1% per hour in sleep mode & how are you doing it?"
I disagee with your comment about old 4.0.2 radios since 4.0.4 (FA02) radios have improved signal reception. It is possible that maybe it affects battery, but I kind of doubt it. Based on all the research so far, seems mostly screen eats it a lot as well as how you use all the apps on the phone as mentioned above. I mean isnt this a matter of some electrical engineering info (ie voltages etc) and how to tweak such things? I have CS degree but admit my hardware knowledge is not greatest.
Ugh, I'm in a mess now, lol. I called Verizon yesterday and followed their usual "signal solution" got me to 4 bars of 4g. Turned on WiFi - 2 bars, turned it off, back to 1-2 bar 4g that last for 30 seconds.
I'm starting to think it's the sim card.
Any suggestions for battery life? Seems my phone can't sleep. It's down to 83% after 5 hours. And all I've done is send 2-3 text messages. Do I turn off NFC for a start?
edit: Now I'm at 4 bars wifi. Goddam radios, they are so random, we'll assume the phone is trolling and continue to the solution.
bump for the night scary how fast it got to page 2.
let's get these issues fixed!
If your phone is searching for signal, then your battery life is already sucking it up. A "stronger" radio that uses a little more juice won't cause more drain than your phone will cause by throwing everything it can at the phone antenna. Just look at my screen shot from before...28% battery drained in 8 hours...an additional 20% due to the phone trying to keep a signal.
Like I said about your original screen shots, your battery life doesn't seem to be that "off to me". Just push different radios, and try them for at least a day.
Okay will do. Where can I find these other radios and how do I flash them?
Lastly, anyone here an expert on fixing phone isn't sleeping? Seems to be my major idle battery drain.

You can find the radios here:
http://forum.xda-developers.com/showthread.php?t=1481095
If you have the 4.0.2 radios, you can flash that ZIP in Clockwork Recovery Mod.
It will take a few minutes so leave it be and don't do a battery pull.
Well I have the 4.0.4 radios, does that change anything?
edit: after looking at that link you provided, are those even radios only? Seems like a bootloader & radio update from 4.0.2 -> 4.0.4. And I'm already on 4.0.4. But with horrid signal.
I have had the best results with the 4.0.4 radios but you mention you are already on them.
You can try flashing some older radios but I am not sure that will help your signal issues.
As far as finding out why you are having deep sleep issues, you can use Better Battery Stats to narrow down wakelocks.
With that said, if the phone is constantly in an area with poor signal, that will cause unnecessary battery drain as well.
Where can I find these older radios?
edit: I'd like to try the 4.0.2 radio.
Update 1: So today I powered it on after having it off from 7:00 AM to 2:45 PM. It's been idle, checked email for replies on this post and this is my battery:
Something is eating up it's idle time.
I noticed on the way back to my House it picked up a strong 4G signal for 5 minutes or so. Still looking to find where the 4.0.2 radios are. Noticing a stronger WiFi signal though, and the usual 4bar 3g. All I can find is the post from adranalyne about the radios from 4.0.2 -> 4.0.4. Something I was thinking about: If I flash 4.0.2 radios, say they are bad and I need to go back to 4.0.4 would that require a whole new flash of 4.0.4 or are there seperate radios?
Here are the betterbattery screenshots: (I have for last unplugged and charged not sure where it needs to be)
I too have an LTE Galaxy Nexus and have been switching from franco's and lean kernel in an attempt to gain battery life. I have a feeling you're not going to get much better battery life with LTE turned on. I've turned off sync and LTE overnight and the best I've gotten in deep sleep is about 1-1.5% an hour. That's all after hunting down all my unnecessary wakelocks and shutting them down (GTALK_asnyc, etc) and keeping my running programs to a minimum (email, lightflow, and weather1 are the only ones ever running besides stock apps with sync on weather1 on a 6 hour cycle)
All of the two day battery life posts I've seen all seem to be GSM phones, and typically I've been getting a full day pretty comfortably...
8 hours while sleeping + 8-13 hours of light to moderate usage (1-3 hours of screen time generally)..all with about 10-25% remaining at the end of my long days
That's excellent. But one problems: (1) I can't even get a 4g signal, at most for 5 minutes in an area that I regularly get it. I have a thunderbolt next to me running 3-4 bars. I know the GNex has a bad radio, but sheesh I atleast want to have SOME 4g.
Been trying to find a radio, can't find one though, if you can link one that'd be appreciated.
Anything you see there in betterybatterystats I should shut down, and do they start backup after boot? I see the GTALK thing you were talking about on mines too, how do I get rid of it?
edit: just a few hours after my first post today:
I am on phantom hackers blazer rom 4.0 with the fb15 modem and when I first flashed I was getting a good 40 hours under moderate to heavy use now it seems like I struggle to make it through a whole day on one charge. What could be causing this deterioration? Seems like my idle battery use especially has gotten allot worse. I used to lose less than 1 %per hour now I seem to be losing around 4-5% per hour.
Probably the modem. Go back to the old one If you were getting good battery life with it.
Sent from my iPhone killer.
Well thats the reason i switched to fb15 from el29 is because i was getting horrible battery life on el29. Fb15 was good to me for a good while. Just for some reason the last couple days the battery life seems to be deteriorating. Should i try wiping battery stats?

YES! Honestly I did not even think of that! In my house I am always getting 2 bars or less and sometimes I am even in roaming. I dont know about trying the new ICS modems though I have heard allot of reports of them making peoples phones really hot.
I struggled with the same problem, I moved into the lower level of my house and my battery life seemed to almost be cut in half. I usually get 1-2 bars down there vs. 4 upstairs. Now I know what the problem was. Thanks!
I'm at a loss here, but I know something is wrong for sure. I'm familiar with the low signal strength 'problem' on LTE networks as described at rootzwiki's thread entitled "This is why your Verizon Nexus signal "sucks" " I do not understand it inside and out, but I know enough to be at least 80% sure that this is not my issue. That thread describes a low signal strength, as in the dBm, but my problem is actual performance. I'm not comparing numbers (at least not on LTE networks), but results.
The problem is pretty bad, and pretty consistent. Without fail, my signal strength will be butchered, and with it data and even voice/text service will be unreliable or non existent inside any building. Not just some buildings, but any building. If I'm in a 4G area, I almost always lose the 4G, and it's switched to 3G with very poor performance (even for 3G standards). If I don't loose the 4G, the speed test results are horrid. I've had several cases where inside a building I still have 4G but the speeds might be 500-700 Kbps down/up or even worse, but when I step outside into the parking lot, 10-15 Mbps down 5-15 Mbps up. I realize structures absorb wireless signals and sometimes it can be pretty bad, but this is too much and too frequent to just be normal wireless signal degradation. It also doesn't seem to be the area because I've traveled through these areas before with my droid charge and I've never experienced issues anywhere close to this bad with my charge.
Some examples; the first time I noticed it was in the Greensboro, NC 4G area. Specifically at the Travel Centers of America about 10 miles east of the greensboro's border. When I first pulled into the truck stop (I drive a strait truck with a sleeper) I was pissed because my phone was on 3G, and I looked this area up before I came here on verizon's detailed 4G coverage map. This very truck stop was sitting in a dark maroon 4G area, NOT an extended 4G area. So I was angry, but I figured that there was an issue with the network, or the storm coming through was causing problems. Later the storm passed and I noticed (while walking back to my truck) that I was getting a strong 4G signal and good speeds, 5-10 Mbps down and 5 ish up. But as I sat back in even just the driver seat the signal strength dropped, and so did the speeds. I did a lot of tests later outside. I was performing speed tests at different locations all over the parking lot and I noticed the closer I got to the trucks, the poorer the performance. When I was inside my truck, and back in the sleeper, 4G was gone completely, taken over by a very poor 3G signal with slow speeds. I found that if I had my phone mounted on the windshield I was able to get reasonable 4G speeds, but still only a fraction of what I was able to get outside in the parking lot.
Another similar case happened in the Washington DC area at a walmart (Landover, MD). This time the 4G stuck even in the sleeper, but speeds were 2-3 Mbps down and about 700 Kbps up. While outside, however, 15 Mbps down and up.
Here I sit at another truck stop. This time, however, I'm in an extended 4G area (which of course means I have 3G) and I'm comparing my 3G signal strength to my Charge's signal strength. I know what I said earlier, but from what I understand about that "issue", gingerbread phones and earlier would give the CDMA signal strength because they couldn't read the 4G signal strength, but ICS and later can and so it displays the LTE signal strength. So wouldn't that mean that if you are in a 3G area, you can, in fact, accurately compare signal strength since they should both be displaying the CDMA signal strength? If that's the case, then what I'm getting is -100 dBm on my Galaxy Nexus and -87 dBm on my charge.
Something is most definitely wrong with my phone, but I don't know if it has anything to do with the Vicious JB stock rom I installed or not.
Vicious JellyBean 4.1 V5 is the version I installed, and I realize now that I did not install the latest (4.1.1 V1) but nonetheless I could not see it reported anywhere in the changelog, or any of the replies to the thread that there were very noticeable problems with the radio performance. I'm just at a loss and I really hope someone's reading this going "ah, I know exactly what that problem is". Although I'm never lucky enough to have a well known problem happen that there are fixes readily available for
Thanks very much for your time and help!

JB issues?
Soundfx,
I've noticed some strange data problems as well. I've only had my nexus for 3 days. The first thing I did was throw a JB ROM (actually, about 9 of them to try them all out) on the device. (Vicious was one of them) What I noticed was that pretty consistently, about 5-10 minutes after the flash, my phone would go from having 4 bars of LTE to no signal at all. My connection would drop completely. Although I didn't figure this out until the latter flashes, I did remember having connection issues when I tried going to the play store or the internet on all the ROMs. I'd have to switch of LTE, and then I'd start working again. At first I just figured that I'm in some sort of LTE dead zone or something. But it seemed strange that my connection would drop completely and I couldn't get it back for 30-60 seconds.
SO, this morning I took my device back to stock. Unrooted ICS from Verizon. And although I wasn't at home for more than a minute to do testing, it appears that my connection problems have gone away. So I'm wondering if it is a radio issue for JB roms. All that to say that I don't think your problem is just the vicious rom. If you wouldn't mind, I'd suggest you trying another ROM and seeing if you have the same issues.
I figure it could be a few things for my own issues, which could be similar to yours:
1. Toro JB roms just have radio issues. (Seems like more people would be clamoring on this forum though if that were true, and I haven't seen any other than you)
2. I have a bad piece of hardware. (Running my stock ICS rom should shake that out.)
3. I live in a verizon dead zone and will experience drops no matter what ROM I use. (Again, stock ICS should shake that out for me.)
4. Gnex has inferior radio hardware, and there is nothing to be done about it. (Doesn't seem likely.)
ALL that to say that, while I don't have an answer for you, I seem to be experiencing similar problems, and I'm trying to figure it out too.
I'll keep you updated as I hone in on a culprit of my problems. (IF I can)

I suggest you upgrade to the AOSP version that was released a couple of days ago. I have been running it for about 20 hours with very good results.

You say "the AOSP" version that was released, but what exactly does AOSP mean? I know what it stands for, Android Open Source Project, but every jelly bean rom I've seen (or most) has AOSP in it and I guess I don't grasp it's actual meaning.
The only thing I know for sure is that I want stock stock stockity stock stock! When devs build roms they tend to always have some sort of a bug or two, and I just never feel like they are stable enough. So I want as stock as I can get! Which is why I installed Vicious Stock JB.
I just really don't know though...I know the nexus apparently has radio problems anyway, but...I guess I can just try the latest roms and see what happens. Are there any radios that I can install maybe that would fix this? :\

Soundfx,
I've noticed some strange data problems as well. I've only had my nexus for 3 days. The first thing I did was throw a JB ROM (actually, about 9 of them to try them all out) on the device. (Vicious was one of them) What I noticed was that pretty consistently, about 5-10 minutes after the flash, my phone would go from having 4 bars of LTE to no signal at all. My connection would drop completely. Although I didn't figure this out until the latter flashes, I did remember having connection issues when I tried going to the play store or the internet on all the ROMs. I'd have to switch of LTE, and then I'd start working again. At first I just figured that I'm in some sort of LTE dead zone or something. But it seemed strange that my connection would drop completely and I couldn't get it back for 30-60 seconds.
SO, this morning I took my device back to stock. Unrooted ICS from Verizon. And although I wasn't at home for more than a minute to do testing, it appears that my connection problems have gone away. So I'm wondering if it is a radio issue for JB roms. All that to say that I don't think your problem is just the vicious rom. If you wouldn't mind, I'd suggest you trying another ROM and seeing if you have the same issues.
I figure it could be a few things for my own issues, which could be similar to yours:
1. Toro JB roms just have radio issues. (Seems like more people would be clamoring on this forum though if that were true, and I haven't seen any other than you)
2. I have a bad piece of hardware. (Running my stock ICS rom should shake that out.)
3. I live in a verizon dead zone and will experience drops no matter what ROM I use. (Again, stock ICS should shake that out for me.)
4. Gnex has inferior radio hardware, and there is nothing to be done about it. (Doesn't seem likely.)
ALL that to say that, while I don't have an answer for you, I seem to be experiencing similar problems, and I'm trying to figure it out too.
I'll keep you updated as I hone in on a culprit of my problems. (IF I can)

Thank you kindly sir, and I will give a few other roms a shot just to see what I can find out and report back!
I tried flashing a few different roms; Liquid TORO Alpha 6, Vicious CM10 Toro, and Vicious JB 4.1.1 v1. All three of them as soon as the phone booted up showed the exact same poor 3G signal quality in the back sleeper while I'm in a dark maroon 4G area. Although I don't think I did a proper rom installation. They roms definitely installed, but it upgraded and installed over what I had...which I didn't realize it would do at all. I'll try doing it properly rom installation with a JB toro rom and then I'm going back to stock ICS to see what it looks like. I'm actually, right now, back at the truck stop that I originally noticed this problem. I'll post back.
I tried flashing back to stock 4.0.4 ICS build with the most recent radios, then I tried EK06 EK05 radios. It was the same across the board. No matter what rom/radios i use, the signal quality was the same. I lost service completely inside the building and in the sleeper it drops to 3G with incredibly poor signal quality :\ -100 dBm -120 dBm I'm going to try and get a new SIM card. if that doesn't solve it...then I guess it's time to look for a new phone :\
It seems like the developers are in a holding pattern until new radios are leaked. If it's that bad, there's no real harm in sticking w/ ICS until we get radios. Some really sweet things have been done by the community in the meantime.

well I already had vicious 4.1 installed with my apps and all that stuff and it's the same across the board. So I'll be sticking with this until something pops up I guess :\ I'm still definitely going to check about getting a new SIM card; it's the only option, short of another phone, that I can try at this poing. -shrugs- :\
I see these questions/statements a lot here and just wondering if they are fact or just a myth.
1. Do AOSP ROMs get worse reception (in terms of dbm NOT "bars") than TouchWiz ROMs?
2. Leaving GPS on drains your battery.
3. Leaving LTE on drains your battery.
4. The latest firmware is the best.
If you can think of anymore, post em!
1. True. If you want 100% functional AOSP, get a Google device. Devs have to hack it to get AOSP on devices that arent officially supported so it wont ever interface with the radios/modem as well as it should.
2. Yes and no. On a completely stripped down ROM with no Google apps and AOSP, it shouldnt be very noticeable. The thing is that apps like to keep track of your location just cuz, or to cache it in case you need directions (example: Google maps and Play store). They keep pinging your location and thats what causes battery drain. So theoretically, if you have no apps that access your GPS or Google Apps installed, you WILL see drain, but not very noticeable drain. This is the case with turning on any radio really (3G, 4G, Wifi, GPS, etc)
3. True, but to an extent. Having any sort of data connection will drain battery. But having experienced both LTE and WiMax 4G in my area, I can definitely say that LTE is a HUGE improvement. WiMax would cause drain similar to being in areas with little 3G coverage (huge drain because your phone keeps looking for towers to connect to). With LTE the drain is still there, but much much less and much more battery-friendly.
4. Definitely false. It all depends on your area, I know that with the MB1 update, most people were getting vastly improved speeds, but then there were a couple others who saw a HUGE drop in coverage and data speeds. I even know some people who are still using ICS modems because none of the newer modems perform better for the places they visit and/or frequent.

1: Not necessarily. Depends on many factors. My service on AOSP 4.1.2 is excellent. But it is also the same on touchwiz, but aosp downloads stuff faster. On 4.2.2 my service wasn't great, in the same area.
2: I have heard that too, I don't see why it would.
3.2: No clue. Elaborate. Do you mean leaving it on where no 4G is or where you get 4G?
4. That is all opinion.
Edit: Dang it nexus! You beat me!
But your answers were more descriptive.

1. I used to use TouchWiz (back before I rooted my phone; and it was stock) and I honestly haven't had a MAJOR difference in reception. Matter of fact the latest firmware (MD4) I'm getting very nice speeds (3G).Although I can admit, TouchWiz I RARELY EVER had a dropped call and once in a while it'll happen on AOSP.
2. I've heard that GPS drain is so minimal and you can barely (if at all) notice it?
4. While I agree with you, the latest firmware (MD4) as I stated above, I am getting very nice reception and on MB1 it was better than previous as well.
