I get at least double that on mine. Have you done a full discharge cycle? I'm on my 3 cycle and I seem to be averaging about 8 hours of normal usage.

Games, music and facebook. You were using your phone heavily. What did you expect? There is no nuclear battery.

Hey guys, I have a question...its kinda off-topic and...dumb. The GSM version is the "normal" Nexus or the 4G LTE Nexus?
Sent from my E15i using XDA App

3hrs 30min of screen on time, and your phone was awake like 90% of the battery cycle. That's pretty much normal...
You were actively heavily using your phone for hours at a time. What the hell did you expect?

I have no complaints. On this charge I did a bunch of reading with Aldiko, playing with Maps and Earth, and some Flick Golf and a bunch of text messages. I don't think I had a single phone call. Screen on time was just over 3 hours. At this rate I could get an entire 24 hours on a single charge.

Mine's the best I've had on an Android phone, my Optimus 3D used to last around 8 hours, my desire around 10, my G1 around 18 (this shows how I use it and what I have running).
The GN lasts around 24 hours, in fact, since I got it around 3 weeks ago I've only been in the red twice.
I went out for my sons 2nd birthday 2 weeks ago, from 10AM until 3PM I was filming a LOT (including using the light when indoors) as well as taking photos. by 4PM it was still at 50%
and I'm loving how quick it charges!

Also, takes me around 1-1.5 hours to full charge...but I am not using the bundled adapter though...
The battery is definitely way way way better than the Optimus 3D.

1.5 hours seems to be normal! take me that long from about 10% to 100% via AC

My last phone took me 2-3 hour for a FULL CHARGE. I think my GN cannot be charged completely.

I'd say the battery life is pretty normal and standard for an android phone. Nothing commendable but not horrible either. It serves the purpose as it should.

I've been reading this thread and I have the same issue on my Sensation (but I am also running a early alpha of 4.0). Last night it took me 2 hours to fully charge my battery, so there is a possibility that it is the software and not the Nexus itself.

3 hours of screen on time with basically zero other usage other than what appears to be a few minutes of some motorcycle game?
Are you just turning your screen timeout to infinite, turning the phone on, and letting it sit to see how long it goes?

Wow, that's pretty good. You could theoretically get ~6 hours screen time with the entire battery which was unheard of prior to 4.0.4. I believe it was generally accepted that approximately 4 hour screen time is usually the max.

THAT is the actual battery improvement, the phone itself uses like next to none to run now, only the screen draining. I went from around 25% Android OS to like 3-4% (as well as other core apps went down).
I use my phone extensively (although no games), and my screen % is like 75-80% (at 95% of the time being minimum brightness [5])

Android OS used 3-4% before the update as well. The ~25% was a bug in AOSP 4.0.2 and 4.0.3. It just showed high use, but wasn't actually draining that much.

No story here. Just a fixed bug.

I'd think that a lot of this power savings comes from not using the LTE modem and just using CDMA. But I'm probably wrong. Makes me wish the 4.0.4 update would arrive here.

Are u on the ota from the uploaded url, or the factory image from google? Iam on factory. Most people will say it dosnt make a diferance, but i am on factory wich will do a complete full wipe and will run 4.0.4 as if you got it out the box with a new nexus.

I'm seeing modest improvements:
autobrightness, 2h music, 4h 3g data, rest of wifi, stock kernel, interactive 350-1200
This is pretty good for stock kernel compared to 4.0.2 . It's slightly better than what I usually get with imo's kernel on 4.0.2

JuiceDefender Alternative

So I've been using Juice Defender for the past year or two now, and though there have been reviews somewhat negative or that it's only a placebo effect or something, it has helped my battery life extensively. There are times where I might accidentally disable it and forget to enable it, and my battery life gets worse enough that I notice almost right way and Juice Defender usually helps with that.
The feature I use the most is making sure that Data and Wifi and stuff are turned off when my phone is locked, but with a few exceptions for some applications like Pandora. Just looking for another application that can do something similar, and yeah, there's other things too, such as turning off the WiFi when there it can't connect after a certain interval, and not turning on both Data and Wifi when there's WiFi, for example.
Just looking for another battery application that does the same. Juice Defender has some small bugs on my phone such as messing with the bluetooth and they haven't upgraded their application in like two years now, so yeah, I'm just looking for a more updated application.

I've been using Deep Sleep Battery Saver Pro and GreenPower Premium. I have to say the first app is not as customisable as the second, but it's pretty smooth, effective, has a more logical interface and I've never experienced an issue with it. There's also a free version that also does the job. And to all of you sceptics, YES, IT HELPS.

you must try this app. battery doctor.
it saves my nexus 4's battery alot.

checkout tasker. its a little bit overwhelming at first, but once you get the hang of it. Boy your phone can do marvel.
My Tasker Config:
Data Off : when Screen Off
Data On : when Screen On
from 19:00 to 03:00 : Wifi On (when i'm at home)

Only problem here is the 2 day waiting period lol. I'm a flashaholic and its driving me mad lol.......5 hours remaining until learning mode completes. Really hope its worth it ?
I'm a firm believer in giving a ROM/kernel sufficient time before complaining about battery life ( thats why i never complain about battery) so I guess this is giving me that sufficient time to let my phone settle at least.

Using a combination of 2X Battery Saver, and Snapdragon Battery Guru. Works wonders.
Sent from my Nexus 4, the only phone approved by Patrick Star

I am currently using Battery Guru as well by Qualcomm, but I had a quick question. Like slymobi, I like to flash the latest update for whichever ROM I am using at the time. I have about 13 hours left until baterry guru is done learning. My question is, if I do a titanium backup of everything including battery guru and then after installing new rom restore the app with data would I need to redo the learning process or can I just let it run based on the original learning process? Hope this question makes sense.
Thanks!

Battery Guru for snapdragons

Have any of you used this app? I think it's worth at least trying out. I've been using it now for a few days and it seems to have helped increase my battery life. A lot of times before I would get about 2.5 hrs of screen time and now I've noticed I've been getting almost 3.5 hrs...almost, but still good improvement nonetheless.
*It goes into learning mode for about 2-3 days before actually starts helping save battery.
It's free in the playstore, you guys should check it out if you didn't know about it already
Sent from my SGH-T999 using xda premium

Been using it for two days, after initial 2 days learning, and for me it has increased my battery life by a ridiculous amount. I work in an area with little to no service and my phone is almost always searching. I would unplugmy found around 5 am and would be at 30-40% by noon. Apon checking my phone for the past two days its been at about 75%. So I love it!!
Sent from my SGH-T999 using xda app-developers app

Yeah usually I don't really believe in apps claiming to save battery now because none of them ever really worked for me. But this app is made for phones specifically using snapdragon processors and actually works, pretty damn good too.
Sent from my SGH-T999 using xda premium

It must have gotten better from when it first launched because it absolutely DECIMATED my battery life in the first versions! Maybe I'll try it again.
Admittedly, I'm running root66 MD5 and I'm getting the best battery life I've ever gotten without undervolting and the ROM has been extremely stable for me so I'm sticking with it for now... maybe my constant ROM flipping was messing up the app. I'll give it another shot.

I tried it for a week and it wasn't even doing anything at all...
Just get battery doctor from the market should do.

4 hours? I've been getting 5 hours of on screen time with MD5, WiFi on all the time, playing Metropolis and Simpsons: Tapped Out...
Auto brightness on or off? I have mine turned off (the screen is plenty bright at one tick above base).
All I know is that I never came close to 5 hours until upgrading to MD5...

To be honest, I haven't noticed really any difference. I'll get some screenshots later tonight if you'd like, but overall, if there were any battery savings, they have been minimal. Notice my screen-on time in the original screenshot. I really am not a power user. I only ever have to charge my battery during the day if I've been gaming on it or if I have a rogue app chewing up battery. I usually go 12-14 hours and have 25-30% left with less than 2 hours screen-on time. I don't use task killers, however I reboot my phone daily before I pull it off the charger.

Turn bluetooth off of course. Disable factory apps. Turn on power saving mode. The performance difference is non existent, and it disables a few things that drain the battery. Turn WiFi off when not at home/a place with WiFi, I've been doing this to get better battery life since I've had my HTC HD2. Do this stuff, be smart with screen brightness, and the battery life will be really good. Best I've gotten was 1 day and 4 hours on my battery.

Have you rooted your device by any chance? Have you tried disabling Android Device Manager yet?

Nope

I get incredible battery life on my AT&T Note 5. While you certainly may have a bad battery in your phone, I'd still be more suspicious of an app causing problems. The same app installed on different phones can still have different results. The "Held Awake" entry in your screenshot (post# 13) at 2hr+ seems that it might be high considering how long the battery lasts for you.
You should investigate your App Usage entry to see if you see anything abnormal.

Cool. What is that under?
