Ive got the htc 2150 extended battery, im running cyanogenmod 7.1 with the latest incredikernel. People say 2 days with sense roms? I need to charge my phone every night?

It really depends on how you use your phone. I can go for up to three days on my phone with light use. I can also go for less than a day when I have the screen on all the time.
This is entirely subjective as Ralph0015 says. Factors like signal strength, wifi vs. 3g use, display brightness, and seemingly an endless list of factors may affect battery life. With the exception of significantly altering/limiting your use or purchasing the larger extended battery, I wouldn't focus on it too much.
Using the phone moderately and saving battery is tough unless you start messing with the CPU. Setcpu can help by setting profiles for certain states charge/screen off etc.
This is a decent write-up for underclocking the processor with setcpu. It is aittle dated but still helps

yeah it totally depends how you use it. Most of the time I'll end the day with ~50% left, but if I'm trying to save I've gone 4-5 days before (camping trip with no outlet).
This is with the 2150 battery.
Hi,
I have a GN extended battery, and I've noticed it's been draining much faster as of late. I used to get 2 hrs of screen time, now I get just over an hour. I'm thinking this is the battery itself, since I've switched kernels and ROMs several times, with the same result.
Is there any way to test the battery for quality? Other than my subjective opinion that it seems to be draining faster, is there a reliable way to test whether its lost its ability to properly drain?
Flash Stock Rom and enable automatic brightness. If you can get 3 hrs of screen on time everything is normal.

Ummm am I the only one with the simple answer here? Type BBS in the market. Perhaps u are getting wake locks. This is assuming you don't have it installed and are monitoring it of course

I've had my Verizon Galaxy Nexus since launch day. I've NEVER been able to get more than 3.5 hours of screen-on time with this thing. But lately it's been even worse. I'm seeing anywhere from an hour to two hours before I have to reach for a charger, usually right around 1.5 hours of screen-on time. It will sleep for a good long while (no wakelocks causing drain that I've found).
I keep sync on for some Google services, like Gmail, but not many. Battery life doesn't really seem to change regardless of using 3G or LTE, nor does wifi seem to improve. When the phone is awake, and the screen is on, the battery just drops like a rock. Literally every time I look at the battery percentage in the status bar, it's dropped another 1-2%, even if I'm not doing anything.
I've run everything from stock 4.0.2 to AOKP JB nightlies (which I'm currently running, with imo's kernel). I've tried practically every ROM/kernel combo out there and never seen an improvement. I've undervolted, underclocked, played with brightness settings, everything I can think of. It's been wiped, the battery has been occasionally cycled, etc, and nothing seems to improve the battery life--it's only gotten worse over time. I did, at one point, have an OEM extended battery, but it wasn't a significant improvement enough for me to get over losing "the hump" so I got rid of it (actually traded it for a Droid X, lol).
So I'm kind of at a loss with this thing. Does the battery really suck this much? The other day, a coworker with a Galaxy S III on Sprint used his phone for over 3 hours of screen-on time (I looked at his battery stats) leaving him at about 35% battery. Mine was also at 35%, with only 1 hour of screen on time. I understand the GS3 gets better battery life in general, but this is getting to the point of being unacceptable.
Not unusual. Big screen = big power requirement. Poor reception (i.e. bad coverage area) saps the battery the quickest, extended screen time on is a close second. Have you tried the extended battery? It adds enough to get well through a work day and commutes if you're not using the phone as a laptop. However if the phone is being used as a laptop, I'd suggest buying an actual laptop, or better yet a tablet. I get 10 hours of steady use out of my Xoom.

Try completely wiping your device through download mode and setting everything back up

The phone doesn't have amazing battery life but what you're describing sounds pretty abnormal. It may be a bad battery.
Yeah seeing as the battery is around 9 months old, I would first try and get another battery and see if that makes a difference. Most batteries dont go bad that quickly but wouldnt be surprised if it did. Worst case you would have an extra battery that you can also keep fully charged as it seems though you have tried most everything you could regarding any software issue.
My web browsing battery life is horrible. I turned off 4g and I still see my battery drop roughly 1% every minute. That means I don't even get 2 hours of screen on time. The battery drain also seems similar when on 4g so there really isn't a difference. My wifi battery life is a little better. I can maybe get 2.5- 3 hours screen on time. I switched my battery for a qcell 3800mah battery, yet the internet browsing battery life still seems to be the same. Roughly 1% drain every minute. With wifi and the new battery I get roughly 3.5-4 hours screen on time. I have used a number roms from CM10 to Aokp to Jelly Belly, and am currently using codename android and recently switched the kernel to air kernel. My screen brightness is usually 60% and everything like gps, nfc, and auto sync are normally turned off. Is there anything I can do the get better battery life such as using a different radio or is anyone having similar battery issues? Thank You
It is hard to get awesome battery life on the VZW version. I have been dealing with the same. I honestly think my issue is the newness of 4g. I cane from iPhone and inc2 which in my opinion had the best battery life of current phones.

Same issue with mine I've resorted to using my work issue iphone for browsing and the gnex for everything else

There's nothing wrong with that battery life/screen on time. There is no other Android phone that's going to perform a great deal better than that on 3G/4G with heavy web browsing. You're expecting more than what exists in the public technology and hardware at this point in time.

I appreciate the replies and feel a little better that I'm not the only one having problems with browsing over 3g. The weird thing is though, that I'm still getting less than two hours of screen on time of straight browsing with the extended 3800mah battery. Wouldn't the battery be at least at 3-4 hours cause its double the capacity. Also what are the temperatures of your phone after heavy use, because the top screen area of my phone gets extremely hot and the temperature can get to 120 degrees.

Try out SetCPU and if you like it, support it by buying it in Google Play.
I use Franco's nightly 241 with the GPU OC'd at 384 and the CPU underclocked at 1GHz. If I start seeing the phone get jittery, I bump it up as needed and the kernel supports up to 1.8 GHz. If I walk around with it at 1.0 GHz, I can get moderate to heavy use out of it from 7:30 to about 6:00 on the stock battery.
The versions of SetCPU that are up on that post are over a year old. If they don't work (which I haven't tried them on the gnex), just test one of the free ones on the market.
Running 4.2.2 I get 9h of standby and 1h screen on at the most on a HSPA+ Galaxy Nexus using a OEM 2000mAh extended battery.
I checked wakelocks and there was nothing out of the ordinary. Anyone else getting this bad battery life?
A phone that dies half through the day with light usage is pretty much useless. (I've had to use the 1750, 2000 and the 3800 battery to come through the day.)
Depends if you have any apps syncing a lot or using the radios a lot.
Signal strength plays a big role in battery life as well.

Only Gmail/whatsapp sync a bit, the rest is all turned of/ wifi only. Used gps maybe 20min for google maps ans public transport.
Signal strenght was mostly good with the occasional no signal, 10 min total.
Still, it shouldn't be this bad.

btw im using sprints galaxy nexus running the unofficial xylon, with ak diamond19 kernel, with lte off, and pie controls.
Same here. I'll charge my phone to 100% set it down pick it up 15 minutes later 8-11% battery gone. No GPS, screen turned down, underclocked. I don't get it. I have a Toro also.. Just have to make due I guess till I figure it out.

I just started using a Nexus this week. I came from a RAZR M. The first thing I noticed was the lack of battery life. I found a couple tweaks to help with this issue.
They are: disable network time and date sync, 3g only till you really need to charge through some web browsing, undervolt to 1GHz, and minimal to 383 or so. I flashed the Franco kernel and use the Wheatley governor. Auto brightness was on auto. I also have the 2100mah battery.
I can almost reach 3 hours screen time per charge. I didn't realize that's a feat so I haven't taken a screenshot. My M got around 5 hours screen time. Ugh.. But the Gnex has won me over.

Something is definitely wrong bro... I have the same gsm model with the stock battery. With light usage I can easily go about 36 hours off the charger with 3 hours screen time. Sync with Gapps, Facebook, Keep, Drop box, Google +
Something is Jacked up somewhere...

Use trickster mod to see if your device is deep sleeping. I've had deep sleep issues on 4.2.2

And if you undervolt too much it will actually destroy your battery life

My device is deep sleeping fine, it is really a 3G/data issue. On wifi I can get 4h screen on and days of standby, no problem. But on mobile data my battery just evaporates in thin air.
I think the real problem is the 3G radio power management, that was excellent on 4.0 or 4.1 (never had issues) but on 4.2 it is outrageous.
The thing is, on wifi (home/work/...) I have the possibility to charge my phone. If I'm on HSPA+, I haven't.
My stats on wifi at the moment: 2h standby, 35min screen on 89% left.
Select 2G only if you do not really need 3G or LTE for phone and data! For simple phone calls or texting, the quality is not much different between 2G, 3G or LTE. In fact, in my city, there is more 2G than 3G and LTE transmissions.
It will at lease save you 30% battery.
I can put my phone on 2G only, but than I can't search something when I'm on a call, get delayed sms (really noticable). Not mentioning 2G is a pain in the ass, even for IM and email.
And constantly switching between 2G and 3G is also not a good option for battery life. Turning LTE off on a maguro won't do anything.
It doesn't matter how many features you turn off, battery life will not improve. Your phone will become a dumbphone and it will still die on you. I recommend to stop turning on the screen constantly and use it lightly. The screen used on this device is not efficient at all. I hope the next Nexus greatly improves on battery life or I'm switching to something else.

Android OS is high, BBS will tell you what it is, it's usually a kernel wakelock. Also if you don't use Maps, disable it, because since they brought the offline prefetching, it starts services like mad and runs in BG. Android AOSP has it's own location services and MapView, so you won't loose that.
My phone has become almost unusable after receiving the 4.2.2 update (on Verizon, totally stock phone). Battery has gotten as hot as 113F at times, and I can watch it decrease 1% at a time very quickly...
BBS keeps pointing to Exchange. I removed the account the first day and added it back in and that seemed to have helped initially but now is no longer the case. I haven't wiped the phone in over a year plus so this is my next step.
Is there any way to see what apps were recently updated?
Same battery problems for me (maguro). Not long ago I could use the phone for around 48 hours without charging, and suddenly one day to another it all changed and is drained within 9 - 10 hours. I have tried everything:
- monitoring with betterbatterystats (nothing out of the ordinary),
- tried different roms (including stock 4.0, 4.1),
- tried monitoring with betterbatterystats without any apps installed (disbled google apps to prevent syncing), without wifi / 3g / location services / NFC etcetera, even without sim card. --> No big battery draining wakelocks.
- tried different kernels
- tried new battery
- checked if phone was going into deep sleep (did that fine)
All without any impact, the battery life is still very bad (easily draining 5+ % per hour, if it is on standby all the time).
I'm starting to think it might be a hardware problem, I don't know what to do anymore without sending it back for warranty.
3 initial things I always look for when diagnosing somebody's battery woes:
1) Have you loaded (adb then fastboot) the totally stock nexus images from Google's website? At least for 3 days and no additional apps installed
2) How old and what is the usage of your OEM battery? If you're using a 3rd party battery who knows what will happen
3) What's your signal strength like in your daily travels? Bad signal will eat your battery almost as much as screen time
If you still have bad battery after thinking about those 3 questions then you have a unique situation. Otherwise, your problem might be simpler than it seems
IMO, turning off gps/wifi etc doesn't really help with battery life, at most 1-2%. Usually what causes battery to drain faster is when apps prevent the phone from sleeping, or if they're constantly running in the background.
