Need more info, my guess is a background app. Looks like you are stock 100%? That's your problem, lol... Just messing. What is your screen time? Click on display to see that... You're in a 4g area so signal shouldn't be the culprit. Your media is #1 user, but why, were you using it?

More like an hour and a half close to 2..if you used it for like 20 to 25 minutes I would think it's common. Like dude said above me we need screen time, also data technically eats battery away faster than wifi just a thought. Brightness is important too maybe you can try power saving mode, don't expect much difference though. Darker wallpaper helps, but most importantly are you auto syncing and if so which apps it usually starts there. Every little bit helps, most powerful phones have average battery life. Unless you start undervolting voltages and cpu that's where you see the big difference.

also, when i try to flash ANYTHING it comes up with an error. any advice on that as well? i really want to try a new rom as well.

Has to be a rogue app. Try wiping the phone and reinstall everything with increments to get to the root of your problem.

What's your battery usage graph look like? You just say "draining fast" but we can't see what your usage, wake time, or network look like.
Some more info on what you're running would be nice? any custom kernels or roms we should take into account?
Dynamic IP routers will do this to you, which is what I'm assuming is happening.
You ARE on WiFi during this time, right?
If you can set a Static IP, try that.
If you can't...there isn't a known fix.

That's the first I hear about that, but it could be, especially if the lease time of the IP is set too low...
Well I'm on Cm9 with Cm9 kernel
It's not going deep sleep as you can see in the Android system screen shot and cpu spy

I'm not sure, but your phone sure is awake even off of Wifi...
Take a screenshot of the "Alarms" in your Battery Manager app.
You have an app/process (or a couple) keeping your phone awake 100% of the time. Track it down and you've fixed your issue. Whatever's running that "PowerManagerService" process.

And secril_fd_interface is fast dormancy. Your network may not support it.
I didn't realise the gnex had fast dormancy.

I'm not sure where to check that.
It has been a light to moderate day. But I'm pleased with this battery life even so.
What I am eager to see is if the back half suddenly drains faster. (i. e. This turns out not to be 'real')

100% awake time, horrible battery life.

Okay guys, I hope this phone gets better battery life than 8 hours, and I'm not hard on a phone at all. Any ideas on this? My wake locks are horrible for some reason and I'm running the synergy r71.

Install BetterBatteryStats. Great tool for identifying what's killing your battery. You may post some screenshots if need be.

Deep sleep battery will help alot as well your at 49% so if you think of it by the time you are drained to 10 youll probably have about 18+hrs of battery

Yeah alot of people freak out when tbe phone gets to about 50% they don't realize that thats half the day usually. ... and it also depends on how long your last flash was it takes a few days forvthe kernel to settle.

Heat issue / over heating

The heating / over heating people notice isn't the phone itself...
What the heat or hotness people feel coming from the back of the phone near the l.e.d is actually where the contact points are for the WiFi...
So its not the battery or CPU over heating its the WiFi actually pulling an excessive amount of juice while trying to either connect to a poor router signal or a heavy download...
Sent from my LG-LS970 using Tapatalk 4
Interesting.... Is this a fact? Cause I run wifi all the time at my place on lifeless and there's no heat, but on cm or dirty unicorns it heats up. The same spot you mentioned.

Yes I will post pic of were the contacts are located and where they meet the back of the phone...

Interesting.....
I never wouldn't thought it were the Wi-Fi but now this actually makes sense. A couple of times lately I've noticed my phone burning up just doing routine downloads. I knew it wasn't anything taxing the CPU too much...

That's interesting. I've noticed that it heats up pretty nicely while I make my daily back ups for Stock and AOSP.

If you look at the CPU or battery temperature, it's usually hot when the back feels hot. All that depends on the thermal driver in kernel. I haven't played around with that a ton, but usually show-p1984's from bricked kernel for the N4 works well for me.
Sent from my LG-LS970 using xda app-developers app
I turned off that thermal daemon monitor from a thread awhile back... figure it makes a good hand warmer. if he dies, he dies lol.

What is this little "eye" icon for?

Can anyone tell me what this little icon means? It doesn't have a corresponding item in the notification area.
Is it related to that feature that keeps the screen on when you're looking at it, maybe? Screen shot attached..
Thanks,

That's the smart eye feature built in with the phone on stock or the ROM you are using.. Basically if you're looking at your phone, it will stay on as long as you are looking at it and thus you will see the "eye".
If you want a further explanation let me know. That's pretty much the simplest easiest way to explain it.

One more question.. Any idea what impact the Smart Eye feature has on battery life? My battery life sucks since the 4.3 update so looking for any way to make it better. Do you think turning this feature off would help?

Turning it off could help a little bit. I found that ever since I have gone up to a 4.3+ ROM, my battery life has been atrocious.

Only in so far as not having your screen helps save battery.
Get better battery stats and check your Wake locks and deep sleep time
