Hi,
I'm on latest ATT radio 1.54.07.00 and not happy with battery life, i did not try other RADIOs since I know how dangerous to flash it. I'm looking for opinions which other RADIO ROMs are best of ATT and for battery life.
If I can save on battery life and have the same good reception then I'm willing to take a risk of flashing. I don't care about 3G etc, only voice.
I've tried all of them, and I keep going back to 1.48. Works the best for me.

Yeah, that's what I heard. Where do I get it from? Is the 1.48 on this page is good (http://wiki.xda-developers.com/index.php?pagename=Hermes_ExtractedRadioRoms)?
I agree, 1.48 has given my the best results on the east coast.
1.48.10
I am in Michigan and get the best reception/batt life with 1.48.10
I am also however in a non 3G area as of yet, so I dont know how the reception is in a 3G area.

Your quote says you on 1.35. Anyway, where did you get 1.48.10?
Actually, you are not on the latest radio... 1.54.30.10 is the latest and I find that it works really well... I just have a lot of stuff going on, such as constant pulling of POP and Exchange email and Emoze, which monitors a different exchange account... Will all of that, I still get an easy 8 hours or so, before having to recharge.... I have gotten the best reception with this radio as well... And I am in NJ....

Can you install acbPowerMeter and see what is your average power consumption is with only voice and bluetooth enabled and phone in idle mode (screen is off etc)
I was getting around 50-60 mA on old radio and about 20-30 with newly "upgraded" 1.48 one.
1.48's good here in Hellaware. Good GSM signal, and full 3Gizzle signal in most places. I had 1.54 but couldn't stand the battery drain...
I'm using 1.54.30.10 as well. It seems like the same battery life, however I haven't tested with the above suggested software. I can say that I can pick up 3g in places the other radios couldn't. At least it is a lot quicker to detect and use 3g than 1.54 or 1.50. I don't recall if I used 1.48 or not. I'm also in NJ. Good luck.
1.48 works great for me down here in FL, and when I was visiting up in NJ.

The biggest question for me and others probably how battery life compared to newer version of Radio. I definetely saw improment (see my previous post) when downgraded to 1.48, was wondering if somebody with newer radio can run the same utility and see their power consumption.
In NJ, AT&T
I am running 1.50.00. Previously used 1.40.30 and 1.48. 1.48 seemed to be the best of the lot but 1.50 is nearly as good so I stick with it. I found that 1.48 had the best balance of signal strength and battery life. I think 1.50 has a slightly better signal strength, but somewhat lower battery life than 1.48.

Where can I find acbPowerMeter? I will load and compare for you.
I've been running 1.54.00.10 since the day it came out. It has been the best compromise of battery life and recepction for me. I live in NJ too.

Hey people,
following on from artisticcheese's thread about battery consumption Ive performed a few tests on some different radio versions to see what the actual difference in battery consumption is.
Right now (as of 16-01-2008) I recommend the following radios:
1.47.30.10 with an overall score of 1.22 (the highest in the test)
or
1.54.30.10 with an overall score of 1.21 (2nd place).
Remember people, if you are planning on changing your radio version, flash hardspl, and make sure nothing is running which will interrupt the flash process. The radio flash is still the most risky of all flash processes and it is possible to kill the device so be sure before you flash. In doing these tests I performed over 10 radio flashes in a day and i made usre nothing CPU intensive was running on the PC and that i wasnt going to unplug the USB by accident etc...
-------------------------------------
Test Run 16-10-08:
Before running these tests the phone was soft reset, ALL today plugins shut off (apart from x button), internet explorer for downloding and acbPowerMeter for power monitoring.
All tests again running on WM6 "V3 cabb'd III".
This set of tests is the following:
Test 1: GSM mode, backlight off, downloading for 5 minutes.
Test 2: UMTS mode, backlight off, downloading for 5 minutes.
The results vary and a pattern ive noticed is radio versions 1.47.30.10 and 1.54.30.10 seem to have the same behaviour in GSM modes, perhaps the extra ".30" in the version number denotes a particular tweak or feature??
Radio_Power_Tests_16012008.zip
Enjoy.
-------------------------------------
Inital test run:
Using a freshly flashed version of my "V3 cabb'd" ROM which is a tweaked version of pandora naked 6 3.60 ROM with nothing installed so a lean install and using acbPowerMeter I ran the following tests on each radio rom:
Test 1: Backlight off, automatic standby disabled, all processes stopped using start>settings>system>memory. GSM only and phone left on idle.
10 minutes and average current consumption recorded.
Test 2: Same as test 2 , UMTS only.
Ive taken a screenshot of the data with magicss and normalised the results so the earliest radio version tested is the baseline score.
The results of the first test are in the attached spreadsheet and screenshots.
Conclusions:
The results show that overall the differences are neglegable for these tests, however I still believe there is a major difference in practice. So the next load of tests I propose will test the power consumption with data connection attached. Somehow I want to test during a call or download since the HSDPA power consumption is likely to be a BIG number.
how comes you didnt test the latest radio versions? *waits for more results*
nice idea though
each test involves flashing a new radio (20 mins-ish) and two ten minute test runs...I need to use my Tytn today so can probably try the other radios later on, it takes a fair ammount of time for each one so i only went from the ground (1.43.00.00) to the one currently on my device (1.47.30.10) last night. I abandoned doing the later ones until ive figured out a worthwhile test to run for ALL versions. Ive presented my findings so far to show that essentially the 4 versions i tried are identical under idle conditions...not really a true to life test.
..big thanks to u bro! ..awesome work as usual..

Yeah, I think it will be the 3G call and HSDPA tests where the benefit of testing will be found.
My own tests show little difference in the idle power consumption.
I made very good experience with 1.41.00.10.
Good signal and low power consumption!
I've changed from 1.54 to 1.48 and I can honestly say my phone goes another day or two without charging!!!!!!!
Im gonna do some more tests tonight on the new format probably with some sort of download running (web n walk is usefull hehe).
So i'll post some more results later on if i can.
The best radio rom I've ever used
I tried many different radio roms for my Jasjam, believe me the best radio rom I've used regarding to power usage and signal is 1.46.00.11.
Even when using UMTS and 3G, in other radio roms; when connecting to internet with my laptop, I mean using Jasjam as access point to internet , the battery drains fast even if the Jasjam is connected to charger. but in this radio rom, when the charger is on, the battery stays stable and the Imate can also get charged. I know that this radio rom is designed for Trinity which is GPS enabled, but I am telling my experience. THANKS
For your testing goodness, here are pretty much all the radio roms I have ever come across.
http://www.crc.id.au/files/xda/Radio_Roms/
They are in .nb format - so you'll need to use Duttys tool to get them into .nbh files.
The power consumption is definately related to voice call usage.
My normal usage in a day means I use about 50 - 80% of my battery.
Whilst away in Tenerife I used my phone exactly the same but without making voice calls and I only used 50% after 3 -4 days.
This is certainly true. I was away in a place with no mobile coverage (no GSM or UTMS) and using the device for GPS navigation only I was able to get 2-3 full days out of the standard battery.
What is necessary to detect the correct battery consumption?
Something like this: http://www.vandenmuyzenberg.nl/PowerGuard/ ???
Should I use this tool?

Experienced exactly the same thing when I was in Majorca. Even though I did use the phone a lot for sending as MMS (as that was free for me) I still got more usage out of the phone in Majorca if I had done pretty much the same usage pattern over here (UK) and that is because I suspect there transmitters put out a stronger signal, which means the phone has to 'work' less to get a stronger signal.

Sorry for double posting, but I read that those tools doesn't show the correct consumption because they needs power themselves and therefore distort the result... Maybe somebody can confirm this? Thank You.
A very good point. I've known the radio kicks up the power when you have a low signal, and if it's lost - I turn off the radio until I get back to a good area or it really kills the battery fast.
Just thinking here, but to add another level of complexity to the testing - while statically measuring power drain without moving the device will give repeatable results, could a radio power draw "react" differently to signal strength variations, and not be as "efficient" compared to others while on the move (typical usage)?
For example, if the signal goes above 50db (no idea if I'm even using the correct scale here ) it incrementally increases power by 20% for 10 seconds each until an "acceptable" signal level is reached. Once this is achieved, will it reduce back down - say you came around a building an now have a better signal? How long will that take? Will some radios respond more rapidly than others - optimizing power usage vs signal strength?
Dammit Matt! Now you've really got me thinking
In a bit of the background on this, the GSM/UTMS protocol allows the base station to tell the mobile to increase or decrease the transmit power of the phone. This allows it to tune the performance of the phones radio to get the optimum signal level at the cell site. It also helps a heap in deciding what cell towers to jump between and all the critical handoff levels and names.
Much more info can be found:
http://www.patentstorm.us/patents/5357513-description.html
There's a lovely paper about it all here - but I don't want to pay for it
http://www.actapress.com/PaperInfo.aspx?PaperID=18185&reason=500
power useage is down to lots of different factors, one of the main culprits is use of HSDPA/3G and it bounsing up and down between it and GSM when the local Cell doesnt support it or has a weak signal.
I can't believe the statement made above about the battery being used quicker when you talk, of course its going to drain quicker, its permanently transmitting for gods sake
It also depends on how strong the signal to the nearest cell/Base Station is, if its a week signal then the radio/phone will bounce around to find a stronger one, I believe typically a phone will register with up to 3 base stations to enable you to auto switch between cells when you move.
if you're really bored and want to dig into how GSM works heres a starter for 10
http://www.fci-cu.edu.eg/INFOS2005/presentation/GSM_Concepts.pdf
If you want to test weak signals stick your phone in a tin box, assuming this doesnt kill the signal totally then the phone should start ramping up its power output and sucking the battery dry quicker.
My point was made in reference to the testing of the phone to see what uses the most battery and indicating that we should direct our testing at the phone application over any others.
There are way too many thread where this is relevant and I think it is important enough to warrant its' own thread. I can confidently confirm the 26.06.02.27 is the source of many battery drain issues. I'd been battling battery drain on standby using CM7 for the past week and narrowed it down to the radio.
If you are using Virtuous or CM7 (I obviously use both), I recommend using either 26.04.02.17 or 26.03.02.26. Both radios are offered here:
http://files.virtuousrom.com/vision/radio/
Please do not discuss HOW to flash radios in this thread. There are many guides on that subject. Mods, if you think this should be part of the other threads, I understand. There's just so much misinformation out there I wanted to make sure to get my findings out there.
Finally some common sense! I too arrived at the conclusion that the radio was the cause of the dramatic battery drain, but only after pulling my hair out and removing most every app and turning off all syncing. I've been on the .26 radio since yesterday and battery is back to normal.
How did you determine that? I've been using this radio for two weeks now and I have not notice any drain. Just last night, I charged my phone at around 30% after two days of use.

Without changing any other configuration, I've done tests over the past few nights with the phone on standby the entire duration without being touched. Using the .27 radio, I was seeing 5-6% drain per hour, versus 1-2% with the .17 and .26 radios. Nothing else changed and my usage was constant.
If you're having success with the .27 radio, you're probably an exception. I suspect most people are going to have problems with it.

I had the exact same issues with the 26.06.02.27 radio as well, excessive battery drain.

You need to take into consideration that these radios perform differently depending on the location of the user which is why it's impossible to determine which radio is actually the "best".

That's not true either, WWE are the "generic" radios that have decent performance in all areas. It's the provider specific radios that generally have the issues.
I do kind of notice more than usual normal drain when I use my phone but when it is on standby it is awesome. I can keep it on standby for 4 hours and the battery will still read 100%. I have flashed the lib files associated with this radio also.

I have been running the .27 radio for a couple weeks and see no excessive drain. I had drain issues a couple times before using the .27 radio but those were determined to be from a stray app and market updating issues.

Oh snap. I just changed to that radio last night. I did notice a bit of battery drain but not as much this morning. I'll continue to use it and see what happens. I've heard that the reception with this radio is apparently really good which is why I'm trying it.
We'll see what happens. Thanks for letting us know, rmk40! Hopefully I fluke out and it doesn't cause excessive battery drain though

Of course but keep in mind this radio was released for the Australia market. No where else yet. So it's not that surprising it's causing drain for most people.
Didn't change much for me. I was hoping for improved reception but didn't get that either
I have to agree with the OP. I flashed the Aus radio to fix my GPS in which it did but having using my phone for like 3 hrs lastnight and draining down to 9% left I had to flash the TMO OTA radio back. After flashing the .26 back and running fix_permissions my GPS is working and my battery life is better.
can anyone make a recovery for this?
.26
for some reason flashing through computer wont work for me -___-
thank you in advance.
I havent noticed a drain using SenseGinger 1.0.1
I updated hoping it would solve gps with newest nightlies but no bueno. My battery has actually improved. I'm on 26 hours with 22% life left on moderate use

Let's put it this way. The .27 does in fact give off a serious battery drain, in certain areas. Seems like us on the west get significant battery drain while those on the east like it more. Maybe?

i live on the west and i do notice a battery drain.
but .27 is the best radio with the fast 4g speeds for me
.26 was horrible when it came to that
going to try .17 and will report back
Update :
4g speed is good. Not as great as .27
Battery so great far is great so I'm happy
Reception is the same so far as well.
Will report back in a few days.

Tell me how .17 goes.
Maybe in a few months, .27 will be good for all of us. Just im tired of killing myself over this damned .27 radio. im back on .26 and i dont think im going to leave it.

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.
---------- Post added at 03:17 PM ---------- Previous post was at 03:06 PM ----------
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. 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.

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 just got upgraded to LG8 (finally), and while I am experiencing faster data speeds (usually 3x faster than previously), I have some other issues.
1) Music Hub doesn't work, unlike what the log says on sprint.com
and
2) Battery life is terrible!! It drops 6% battery life in one hour, completely idle!
Is anyone else having similar issues? I called Sprint, and they said that they have never heard of either of these issues for the GSIII and told me to take it to a Sprint Store (conveniently, it is $35). Anyone that has issues with the LG8 update needs to call Sprint. That way that can't simply tell us that there is no solution and that no one else is reporting an issue.
I am unrooted and completely stock.
Yes, I did notice after LG8 my battery life was worse... and the phone was a lot more laggy...
I live in Central Jersey and My 3G speeds have always been garbage so I havent notice anything with that.
It seems like everyone has different results with the different radios. If you don't have a good signal in your area, then the two lg radios can drain more battery. If you need more battery life then you could try going back to lfn.

Everyone has different results with radios because everyone attributes everything to the latest thing they installed. Further, almost no one is willing to do any kind of even remotely scientific testing. They just use the phone, check it, science.
Which is why everytime anything is released, you get this huge range of things that, in most cases, can't even occur.
I flashed and had trouble with all 4 radios, lg8 seems imo, to be the most stable, less loss of data connection to my Airvana for sure.
