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?

So, I'm fairly certain it's a well-established fact that the constant switching from 4G to 3G drains a lot of battery on our phones since 4G isn't a widespread service yet. I have also heard that 4G is a more efficient antenna and if you have a constant 4G connection, the battery life isn't impacted much. I was wondering how much of this is true- I live in Atlanta, which was one of the first cities to get Verizon's LTE service, and as a result, I have a sold 3-4 bar signal of 4G at all times. I go to school downtown, work in the metro area, and live in the metro area. Since I got the phone, I've just left it on CDMA, as the speeds are fine for me and I typically get 30 hours or so of battery life with data and sync on (and WiFi, when available). Would switching to 4G change that number drastically?
Thanks!
Also, a side question: I leave GPS turned on as that only polls when an application calls for it, but I've left Google's Location Services off. Is there a real need to leave that on? With GPS only, I tend to get an immediate reading with wonderful accuracy.
I'm calling bs. Please post a screenshot of your battery life of 30+ with gps and 3g all day.

I'd be happy to post a screenshot the next time I run my phone down. As I said, GPS doesn't drain your battery at all unless you're using Maps constantly, so that isn't really a major factor for me. Also, I DO have the extended battery.
Also, I can't help but note how this doesn't really relate to the content of the thread at all.

Not at all what the topic was about but it's easily possible. I've gotten 30 hours on 3G no problem. Right now I'm at 20% after 20 hours with moderately heavy usage. Close to 4 hours of screen on time.
As for the topic, best way to find out is to try it. Couldn't tell you for certain one way or the other.

Right, I suppose that would be the easiest approach. I just fear starting my day out on 4G and then realizing that my battery is shot when I really need it. Though, I could always just turn data off if I see my battery draining super quick.
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.

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.
Sent from my Galaxy Nexus using XDA
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

Hi,
I'm sure this type of question has been posted here before - I've seen a lot of the posts. However, I'm having lots of trouble finding a good answer for my problem.
I'm using a Verizon Galaxy Nexus with a custom JB ROM and the latest radios. My problem seems to be that Cell Standby takes up a ton of my battery. This problem existed in ICS (stock and custom roms/kernels) and with JB (several custom roms/kernels). I've noticed if my WiFi is left on, the problem is immensely better. It's 3:20PM and I'm sitting at 87%. I'm on about 6 hours standby and that's all on WiFi, no use. If I'm on WiFi, that'll be about 60%.
It varies of course depending on what I'm doing. I've noticed that phone calls use a ton of juice and the screen obviously uses a bunch, too.
Also, it doesn't make too much of a difference if I'm running on 3G or 4G. I prefer 4G as it seems a lot more consistent in staying connected, but I've opted for 3G to keep my battery at a decent level.
OH! And the only thing I have running on my phone right now is an Exchange account, Gmail and Google Voice. Google Now is turned off.
Has anybody experienced this sort of thing? I just can't understand how the iPhone can sit idle for days and my phone can't make it past 24 hours unless it's on WiFi.
Thanks,
Jack
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.

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.
I left my LTE N7 last night on WiFi and i found that it lost 10% overnight.
Dont know is it normal or not,but i didnt find any apps awakening device.
So guyz whats your standby battery life on stock?
its been abt 18 hours since my last charge , the batter is now down to 15% (no sim inserted yet)
these are the stats -
wi-fi is constantly on, downloaded abt 1.5 - 2gb of apps/games.
saw a movie (abt 2 hours) .
read a few ebooks (abt an hour's worth).
played a few HD games (for abt 2 - 2.5 hours, not in a single run)
Chiming in with WiFi only battery results.
My best stock result is 7h40m screen on with 5 days of idle time as well.

My WIFI Nexus 7 is losing 4 or 5% overnight (~8 hours) with WIFI ON.
So... it makes sense that your LTE nexus 7 should be losing more because of the cellular connectivity.
However, I can't tell if 10% is normal or not

Somewhat i agree whit you.
But when MKBH stated that he left his N7 overnight it lost 1% that im pretty worried.

Maybe MKBH configure the wifi off on sleep !?
but I must say that I have a few apps with auto-update every hour or so (falcon-pro, rss feed, etc) so without these apps, maybe I could get a better result.
