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.

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:
Coming from AT&T and a carrier branded GSII (i777) followed by an international note (N7000), I'm evaluating Verizon and the galaxy note. If the service is better, I'll jump from AT&T... otherwise, I'll go back to AT&T and my note.
However, this isn't about the service - but about the phone. I understand that some of this stuff might be CDMA/LTE specific (hence the reason for the title)
The biggest thing I see as an issue with this phone (so far) is the (stock) battery life. It completely sucks. 6% battery drain an hour with the screen on only 3 minutes? That's beyond horrible. I don't have anything loaded on here thats a "known" wakelock issue (such as skype, facebook, etc.) As a matter of fact, it's configured (mostly) the same as my GSII and GNote, so it's easy to notice the horrid battery drain. In the same 1 hour period, syncing the exact same exchange server (push email) account, but with 10 minutes display on time, the gnote drained 1%. (I realize that the note has a much larger battery [and display to drain it], but it's useful to compare anyway.)
If I actually use the gnote (display on), the battery drops much faster. With actual light usage (such as for reading email), I get about 6-8 hours of battery life total. If I use it heavily, I'll be recharging so often I might as well hard wire to a wall outlet.
I'm using the AOKP (m4) firmware - first with the kernel it comes with, and I installed the latest STABLE "lean" kernel last night hoping to resolve the battery drain (so far, it's not.)
BetterBatteryStats isn't showing me anything unusual other than a "modem_usb_suspend_block" kernel wakelock (5 min of 1 hour)
Is this what verizon galaxy nexus users typically deal with? Is the battery life on this device really THAT horrible?
Did I miss a "FABQ" (frequently asked battery questions) thread somewhere? Surely the "google experience" isn't only a quickie...
Thanks
Gary
Battery drain while off should be between 1-5% per hour (From what I have noticed). Try enabling AOKP battery saver which will drop from 4G to 3G while the screen is off which should help with the screen off battery.
Sent from my Galaxy Nexus using XDA
disable LTE, and you'll watch your battery life double.
Or just return the Verizon version and buy the GSM version instead.

Drain should be 1-5/hr with 4G enabled or disabled?
I'm kind of in shock at the battery drain on this thing. I'm pretty fluent with android devices, and I generally avoid any of the normal battery blackholes (such as social networking, skype, etc) I also know how to PROPERLY configure exchange so it doesn't drain battery/data. (make sure the IP number of the exchange server doesn't change when switching to/from internal wifi networks.)
However, this is my first experience with using a verizon android device - and first with LTE. My SGSII (GSM) could get 2days on a charge (2%/hr was normal when not on wifi.) and the Note (international version) could go for 3 days on a single charge.
With the LTE GNexus, 6%/hr drain with nearly no usage would give me about 15 hours of usage before 10% turn off. If I actually want to read my email messages or make a phone call (it IS a phone, you know), I might drop to less than 12 hours. I can't imagine that this is normal - or that google, verizon and samsung would endorse something like that.
(Okay, maybe samsung would... they seem to be going downhill lately.)
Surely I'm doing something wrong and the phone doesn't suck this badly. (I really hope I'm doing something wrong, as it will completely destroy my opinion of google if a "google experience" is a phone that lasts only 15 hours/charge when just left in standby.)
Thanks

the problem with battery life is LTE... its a double edged sword: you get insane speeds at the cost of battery life. every CDMA phone takes a huge hit when LTE is enabled which i think is the reason that apple has been reluctant to release an LTE enabled iphone thus far until the tech matures. im using a GSM gnex (i9250) and i can use the phone all day and still be over 30-40% at the end of the day
even with franco kernel 121 on my miui gn, i still need to charge 3 times a day... this is android.

its not android, its LTE.. as you can see both of you are on verizon
my older HTC sensation actually got over 2 days of constant use easily (dual core snapdragon running ICS) since it was GSM.. my galaxy nexus while not getting 2 days, easily gets 1 day no problem on GSM
AFAIK there is no LTE iphone which is why you see on average the insane battery life on those devices

I've made the change mentioned in another reply (turn off LTE when the screen turns off.) I'm charging the phone back up and will see how things go then.
With both wifi and LTE disabled, I won't be happy with drain higher than 2%/hr (assuming the screen stays off and I don't get a massive influx of email.)
For the person who said that's just the android is, you are VERY wrong. As I mentioned earlier, I'd get 2 days on a AT&T branded galaxy SII (i777) and I get 3 days on my galaxy note (international version.)
I don't know, it has to be something with your apps or your signal. I mean, 6% is fairly high in my opinion, even on LTE. I never turn LTE off unless I'm out of town (which is hardly ever). I usually get anywhere between a total of 15-20 hours of total time, and 2-3 hours of screen-on time. This is with auto brightness enabled, no GPS, no BT, just LTE. All my notifications are push as well. Make sure your signal is always a light yellow-green color (in the battery settings menu), otherwise that will definitely be the big battery eater. May I suggest trying different radios, or flashing a 4.0.4 rom? I think the new radios/4.0.4 roms have substantially increased my total and screen on time.

Which kernel are you using? Which radios?
I just updated my radios to use the 4.0.2 for CDMA and 4.0.3 for LTE. Not sure if that will help battery life, but my LTE d/l speeds jumped from about 6mbps to 24mbps (as reported by the speedtest.net app.)

Imoseyon lean kernel 3.1.0 (I have used JameBond Kernel with similar results). I have the stock 4.0.4 radios (I515 V.FA02). Stock battery.
I also keep my screen brightness pretty low.

No reason to turn your GPS off. It only gets used when needed so will not hurt you battery.
On lte with everything else disabled, sync disabled, cm9 with lean kernel 3.1.0exp1, I get just about a day of usage with about 2 .5 hours of screen life, I think it is possible o get decent battery life on lte.

removing the "my verizon" app (and the associated "data usage" widget) seems to have helped the battery a bit. Now at about 4%/hr on LTE with BT/Wifi off, GPS on (but unused.) Perhaps changing the LTE radio to 4.0.3 also helped. Using that same "lean" kernel that seems to be popular in this thread... whatever he has flagged as "stable" as of this post.
The only thing that runs beyond exchange syncing is beautiful widgets (home screen with hourly weather and time.) No other widgets, weather turned off in AOKP.
Take care

Ok so this is pretty frustrating. When my nexus (sprint version, running CM10-0807-Skank with leanKernel 4.2, stock clock settings) has data enabled, it goes through battery like its nothing. Right now I'm at only 1hr 4min screen on time, 5 minutes of voice calls and the phone has been on for 8 hrs and 20 minutes. What's important to note is my reception is anywhere from 3-4 bars of 3G, I have the LTE radio disabled, and I have location services off as well as sync to try and save battery.
When I am on Wi-Fi on the other hand (and have data disabled when I can't get Wi-Fi), I can get pretty good battery. A couple days ago, I had 2hrs 30 minutes of screen on time, with 1 hour of voice calls and made it through an entire day (about 17hrs) with maybe 10% to spare. With 3G, its 3 in the afternoon, and I've used my phone a LOT less and its almost dead!
Does anyone have similar problems and/or does anyone have suggestions? I thought the Achilles heel of this phone was the screen on time, not having 3G on? FWIW, im using the 08-07 build with LeanKernel 4.2 cause it has been by far the most stable, fastest ROM/kernel i've used (and at least seemed to get the best battery life....).
... 5% more battery has gone since I started writing this post, with 3 bars of 3G..... :crying:

get better battery stats and see what is causing wakelocks on your phone. It will help you figure out what is draining your battery.
Have you tried trinity kernel? 3g will kill battery regardless what you do. it is always searching and updating the network.
Anyway to stop that? Lol

Would switching it to 2g only help battery like it does for GSM? If so how to do that
There is nothing to switch to 2g on sprint. It's different than GSM technology.
It's most likely that something is chewing on your 3g data. You need to use some kind of statistics app to see what's running and kill it.
I typically use the data limit build into android to limit 3g data use on individual apps. That cuts them off whenever I'm off WiFi.
any one you recommend?

I have been using CM10 for awhile and usually find it to be great. However recently I have noticed my phone doesn't seem to last a full day anymore and this is minimal screen time. I updated to CM10.1 (RC2) when it was released, I'm not sure if that contributed or if there's something else I'm missing. I have found the best performance by disabling LTE and using WiFi whenever possible. Still though it lasts 9 hours with about 1h30m screen time. If I use it anymore the battery may only last 5 or 6 hours, and this is just using it for occasional web browsing and some texting.
My service provider is Koodo (Telus) and I live in Burnaby BC, so I usually have a pretty good cell signal.
I have attached some screenshots of my battery usage. This was on a day with only light usage and no music or media used; LTE was disabled and WiFi was on.
Any ideas as to what could be causing this, or if this is normal would be appreciated.
Thanks!

Did you update your bootloaders? If so, you probably have the LK4 modem, I'd try flashing the LL1.
Also, you can download BBS (BetterBatteryStats) from here to help narrow down what drains your battery.
It has been known that CM10.1 has been giving poor battery life ever since the Linux 3.4 kernel rebase. I'm not sure if there is a fix, or if the CM guys are working on it at all... It has been 7 days since the last kernel commit for d2.

I can support this, I am getting about the same battery life as you. Ever since updating to RC2 I have noticed that my battery life has diminished. I have a spare samsung battery, and normally I wake up, boot and go to school and use my phone a fair amount for texting, researching, and music. A full charge will usually support this until around 10-12 hours later, then I change batteries in the evening play more music and web browse. I took a screenshot of my battery history a few days ago, you'll notice that the graph increases without the phone ever being connected to a power source.
Has anyone checked their "Cell Standby" to see if there is any time without signal showing?
If you haven't toggled your LTE off, have a look sometime and let me know. If it is showing a percentage of time without signal, go back to your battery life graph and see if there is any RED in your Mobile Network Signal. If you see time without signal but no red in the bar let me know.
I've got some ideas on why battery life isn't great and I'm trying to build a case for it. Guys who frequent locations with poor LTE (4G) signals are who I'm mostly looking to get data from.
Any information that you guys might have would be very helpful to me. Screen captures are welcome. I've uploaded a couple of myself to show what I am talking about.
Cheers.

Poor signal is one hell of a battery drainer. I would suggest trying different modems to find one that works better in your area.

No no. Modems do not affect this issue at all and with the new phones now a days modems don't play as big of a role as they used to with signal strength. Anyway this issue is bigger than that. CM10.1 isn't reporting 4G low signal strenght correctly. It jumps from -115 at one bar to 0dBm no bars instead of switching over to a 3G signal or showing a value that is accurate like -117dBm.
Flashing back to the M1 release of CM10.1 or even to stock and the handoff from 4G to 3G is seamless. We aren't seeing that anymore with the later released even as early as RC1.
Here is my JIRA report.
https://jira.cyanogenmod.org/browse/CYAN-1209
You can see I've put some work into it. Trust me, this isn't a flash a different modem, change network preferences or anything type of issue. I've tried all that before finally starting to gather some screen captures and information on the way the phone is handling it's network signals.
I've also talked about it extensively in the CM10.1 Nightlies thread in the dev section over the last week or two.
http://forum.xda-developers.com/showthread.php?p=41931891#post41931891
Also my original post was asking for anyone who has seen a time with signal recorded under cell standby BUT NOT showing any red in the mobile network status graph. Different than just no signal at all and red showing meaning you have no connection to the carrier at all.

I can probably come up with some data, when I'm at work I generally get a low signal, I never toggle LTE, though I live in a town of ~8000 people, far from major centres. I believe we have HSPA+, but I'm generally connected to 3G. Right now, I've had normal battery life, (no increasing), and 0% time without signal, should I ever have <0% I'll message you some data. Thanks for your work!
I can confirm that I'm having this issue as well. I live in a 4G city (Boston), but my high school has practically no 4G reception. I noticed that unless airplane mode is enabled in the school, I have a battery drain of about ~1 per 5 minutes. The battery stats shows certain red areas when the signal is close to 0.
I'm running the latest nightly (5/29), but I'm flashing back to the M1 ROM until this is fixed. If I encounter any issues with this ROM, I'm probably going to flash back to stock.
Hopefully the devs can get on this when they have time.

Battery life has actually improved quite a bit since rc2, but when I'm at school, where the signal is bad (most of the time I get "emergency calls only"), I see faster than usual battery drain as well. I think that this is normal though, because even my old dumbphone drained battery quickly when there was no signal.

Emergency Calls Only and Red in the mobile network history aren't what I'm referring too with my issue.
Those two things would indicate you phone had no cell signal at all to your carrier. I'm talking about being on such a poor 4G signal but still being connected to the Roger's network. It's hard to explain.
Anyway I appreciate your input.
There has been a lot of discussion on this in the CM10 Nightlies thread in the dev section if anyone is interested in reading or check out the JIRA report linked on the first page of this thread.

I'm still connected to the AT&T network, but it's a very weak signal when I'm at school.
Just flashed back to stock, and the draining issue disappeared. I guess there's still some issue regarding cell signal that's draining the battery.
I've got the same issue, I thought it was just me. I'm on Rogers
I even lose battery (about 1% every 30 minutes) while plugged in and charging, if I'm listening to music, and checking my phone once every half hour for texts or emails.
The other day at the gym while listening to music and using 1 note taking app, it went from 95% to 15%. When I checked, it said the phone was active for 1 hour and 5 minutes even though I never used the phone.
I'm going to install that bettery battery status app now.
Since I have updated on nougat, my battery quickly goes empty.
I reach a maximum of 2 hours SOT.
According to "BetterBatteryStats", the operating system consumes the most energy.
No matter whether Stock Rom or currently with "PureNexus" and ElementalX Kernel with GhostPepper profile, the battery is still very fast empty.
I also wonder what the Wakelock *job delay* and *job deadline* mean.
Now is the question, do you have the problems since nougat, too.
And is the problem the operating system or rather the battery, what do you have for experiences?
With marshmallow I had up to 5 hours SOT, therefore I will downgrade.
Whether it will be better, I will report.
im finding that when my WLAN is off then my drain is negligible. Whilst with it on i see a steady drain overnight.
That might be how i have my phone setup, but not sure.
I now have tasker setup to disable wifi, location, data and swap to 2g at night (i have terrible 3g/4g reception in my bedroom). it seems to help for overnight drain but not daily usage.
I have never had good battery life with this phone, by the end of the day it is usually almost dead with only about 1.5 hours of actual use.
I have the same feeling.
If you confirm that downgrading solve the problem, I will try the same.
Thanks!
Battery has been fine for me. Your phone is never idling properly from the looks of it, despite not being show an awake. Not sure what that means though.
Is there some issue with your WiFi or data signal? I've not seen the WiFi X myself.

I have not changed my settings so far, only slight improvements, which I have since I own the smartphone.
Mobile Data always to max 3g (have no LTE contract), GPS always on (only device), Wifi also always on and could reach thereby also up to 5 hours SOT.
Then I moved from the Google Stock Rom to PureNexus hoping it would help, well, wrongly thought.
And I have always done a clean installation. :silly:
I've been back for a day now on the last Marshmallow Rom (MTC20K) and I do not want to be too rash, but it seems to improve. :laugh:
I will continue to observe and report.
