I haven't ever had FANTASTIC battery life like I'm seeing from some folks around here... when I first started on Starburst (I didn't keep stock for more than about four hours), I was at around 70% at the same time. I'm currently on Calkulin's 2.0.0; about to revert to Starburst and see if it's ROM-related, now that I've given Calkulin's about a week with a calibration to no effect.
I'm currently undervolted by -75 on all steps, and this seems to have made it WORSE if anything, which I didn't think was possible for undervolting to do. I've been monitoring things fairly closely with Watchdog, and nothing jumps out at me. The phone signal in the pic doesn't look good, but I've been in all the same places as I was when I was getting much better life.
What interests me is that I'm seeing absolutely no usage-based change in battery life. Until that sudden dip you see up there, it was going down at the exact same rate whether I was using it or it was sitting on my desk doing absolutely nothing.
That dip started after I played Fieldrunners HD for about ten minutes during a break at work. After I stopped playing, battery life went into a continuous plummet.
I use Tasker (extensively) to keep things in check; generally speaking, nothing is active unless it needs to be, except for Wi-Fi which is always active as it's my primary method of detecting my locations.
Am I missing something simple-stupid here? If not, anyone got any ideas, assuming going back to Starburst doesn't magically fix it?
Not sure if this will help, but improved my battery.
(1) go to your email setting for each account and change sync update, I believe by default it's set up to check every 15 minutes. With 10 email accounts, it took a toll on my my battery. I changed all my accounts to 4 hours.
(2) best way to kill a task is by holding down home button, going to task manager and kill from there. Market task killers were making things worse for me.
Hope this helps.
Thanks for the thoughts! Sadly, neither of those really apply in my case. I stick with with the default Gmail app, which is all push, and I don't use task killers at all.
I'm running the stock rom with a custom kernel. I did notice that as soon as I went from stock to a different kernel I started to lose battery life. Maybe its something Samsung did? I am still a novice with Roms and what not, but nothing like this happened on my original Epic or my Hero. Maybe the yellow triangle isn't the only thing Samsung put in there.
Maybe the aggressive undervolt is causing your phone to ramp up to a higher state to perform the tasks? That drop is steep with how little screen on time you have

For as little as I know, that certainly sounds logical. I still wasn't getting as good as I would've expected even the UV, though.
I just flashed the EK02 modem with today's wonderful developments; I'm going to wait and see if that gets me better reception and thus better life. If not... now I'm not sure whether to try the new ROM first, or scale back the UVs. I want to try one thing at a time, since it's not urgent that I have good battery life ASAP. This gets me through my day, currently, more or less; I'd like to try and find my root cause so that I'm not just trying things wildly in the future.

Well, the good thing is that as of today, its possible to return back to bone stock and start again so you can mess with a few setups and see what works best for you. I have found that this is the first phone that uses the frequencies well. I haven't undervolted at all yet and I have had great battery life. I did the standard delete Sprint bloat, Social Hub and associated apps, Maps, etc. Also, get BetterBatteryStats. It may give you some insight into what's happening.

Then update to EK02
Got very slightly better today after flashing the EK02 kernel. 23% at the same time instead of 18%... anything could account for that 5%, though, so I don't really think EK02 had any effect on this. Zedomax kernel with stock voltages is next.
CPU boots pro
(From the market & assuming your rooted)
Settings
~Screen off profile max800 min200
~GPU to Conservative max1000 min800
~Nitrous Widget GPU to on demand max1400 min1000
What this should do is downclock your device when on standby by alot. Second for phone calls and daily stuff a clock of 1k will be silky smooth and be a small downclock. Third when you set up the nitrous widget and activate it you will overclock to 1.4k which is stoopid fast my quad score is at 1.4k I get 4500 scores at 1.6k oc but forget batt when I'm using the nitrous. I like too personally keep my phone at a clock of 800 for daily phone calls and web surfing... if I play a graphic intense game ill oc it with nitrous and not worry about burning up my phone because if I set the phone down it downclocks as soon as it stands by and will pick right back up when I'm ready.
Hope it helps here's pics.

If you're talking about the page I think you are, it'll have to wait until at least morning. I just did a full charge.
To wit... I spent 43 minutes on a phone call, and lost almost the same as what I normally lose in that same time period. 6% for a 43 minute call; I'm averaging 5%/hr loss doing NOTHING.
@Dchibro, assuming that's true, what would it mean for me? Does it give me a solution?
So, doing a bit of my own detective work... I've had Watchdog installed for about three days, with aggressive monitoring. I was almost immediately getting a bunch of alerts for two processes:
I initially whitelisted them through Watchdog, dismissing them as system processes that unavoidably needed to run. However, the comment from Dchibro got me thinking and sent me back to those, and I started Googling around. Here's what I've turned up so far:
http://goo.gl/Hsvej (HUGE thread on the issue in SGS2 forums. Haven't had a chance to go through all this yet.)
http://goo.gl/kUcqx (SGS2 forums.)
http://goo.gl/mlWW4 (Nook Color forums.)
http://goo.gl/mNiId (My Google search results.)
Gonna try some of the suggestions on here and see what I turn up. For now, I'm returning to stock voltages, implementing a bunch of those changes and keeping everything else as it is now to see where I end up. Phone will be charged to 100% before bed tonight, and I'll post sometime tomorrow with my findings.
Wish me luck!
So, in stead of waking up to 50% this morning, I woke up to 86%! Which is the same I went to bed at. Six hours of sleep, not a single percent lost. If nothing else, I learned from all this that I can reboot the phone when this bug hits me and and get away from it.
As I suspected. Your Watchdog shot clearly shows that you are/were (sounds like a reboot solved your issue at least temporarily) suffering from the Android OS bug. This bug presents itself most prominently in the suspend and events/0 processes. Unfortunately, a conclusive solution has not been found, but there are some things you can do to hunt the problem down.

Definitely seeing a bit of an improvement, here.
Watchdog alerted me to the suspend and event/0 stuff again about an hour ago, but I quickly rebooted and nothing seems to have come of it. I'm going to try to make a Tasker profile to do this automatically, kinda like Viper's LoS script.
All in all, I'm considering this a mostly satisfactory alternative to draining 80% of my battery with almost no use in eight hours.
Hello Everyone,
Many times while searching the internet for Nexus information, the search keeps having me come to this forum so I decided to become a member. Just got for my G-Nexus the other day, its replacing a Droid 3. Nothing really wrong with the Droid (well), but it was my first physical keyboard phone and I wasn't feeling it, and I heard so many good things about the Nexus I knew I had to have one.
I've had it less then a week now, and so far I love it. Though the one thing I must say I am not crazy about, which seems to be a common complaint, is the battery. It drains WAY too fast. Today though seemed more then ridiculous. I left my house @ 8:45 am @ 100% (right off the charger). Made some use of it on the bus, but nothing much (no calls, no video, no music). Already by 11:30am, I was @ 39%! I mean come on, I didn't even use it that much. Yes, I did notice I left the WiFi on, but it should not have drained that fast. Tuesday I used the device moderately and I was able to go home after having the device on for 9 hours and still have around 40% to spare. Its a shame they cannot make a battery that can accommodate such a great phone.
So some questions: Is it really necessary for me to root this thing to get its full potential? I never rooted a phone before. When I bought the phone, I got a shiny gel case that Verizon sells for like $20 - if I did get the extended battery and door, would this case still fit? I am thinking no. Is the ext. battery even worth getting?
I have more questions, but I will peruse the forums and see what everyone else is saying. So in all I just wanted to intro myself and say I am happy to be part of the forum!
Your battery should definitely not be draining this fast. Install better battery stats(look around XDA) and look at what partial wakelocks you have. Try to remember any recent apps that might have been causing the drain
The 2100mah battery will fit. If you're looking at the 3900mah extended batteries, those have their own custom backplates and won't fit.
I've read that the 2100mah battery adds about an hour of juice.

Sorry to sound dumb, but what do you by "battery stats"..?
And I am not sure what a wakelock is either - if you could explain
Hey,
I got my Galaxy Nexus this week too. This is my third full day of using and I get good 10+ hrs of usage each day. I use it a lot too. At least 2-3 hrs of talking, about 50+ texts, synching 4 emails, and browsing/streaming an hour or two each day.
You should check what drains your battery the most and go from there.

'better battery stats' is an app. go look for it. there's an XDA version
your phone goes into 'deep sleep' to conserve power. wake locks are when something refuses to let it get to that state and locks it awake. This is major cause of battery drain.
Better battery stats is available on the Play Store (ugh hate that name) but the dev is nice enough to give it to xda members for free:
http://forum.xda-developers.com/showthread.php?t=1179809
Aside from looking at wakelocks, go to Settings>Battery, then look at the list of stuff (in descending order) that's eating your battery. I went to watch a movie once at 90%, when it was done the battery was at 18% and I never even touched my phone. I checked that list and apparently Facebook killed the battery. Try and look for apps that might be using up a lot and either uninstall them, replace them, or trun off features that might be causing the drain

Root it?
It's a Nexus man. They're fantastic for root users.
All the roms are AOSP...
And bug free (or...mostly. AS bug free as any google build, generally).

I agree with you that the Nexus is fantastic for root, but it's not necessary for all users. I rooted mine because I was use to with my old HTC HD2, but ,except for changing rom, it's useless when you just get your phone.
I think that you can keep the stock rom, and don't root it. One day you will maybe need it, but the stock rom is very nice, it's enough to start (that's what I did with mine).
I noticed you are on Verizon, bad cell reception can chew your battery for lunch too.
There's something floating around in the development section (sprint I think) called battery mod.
Of course, youd need to root and unlock your device to get it working (takes all of about 5 minutes).
I also had this battery draining problem, but installing a custom from with a power saver governor and the battery mod, it'll drain 1% every 30min-1hour. Its essentially in "deep sleep", as the CPU winds down to 0mhz, instead of the standard 350. With this comes a lower CPU voltage, so less energy is wasted.
All in all, this is a great phone once you tame it.
Look for Black Ice ROM. Its probably one of the best here because it let's you choose a stock look or a custom look

Well folks, I took time to study our G2 battery to really see what is killing it. After testing it on different roms i have come out with something that can save your battery for a while before you think of replacing it.
On a general scope these are the main factors that really drain your battery:
1.3G data connection
2.Screen brightness
3.Rom type(mostly sense roms)
On 3g, if the user has a wireless network nearby i suggest you connect to that for your browsing and all that, there is no need using hspa when you have a WI-fi network working great, 3g networks drains the battery faster than you think i tried it and i saw that the WI-fi use was very slow in draining the battery up to the point i switch to 3g. IF your thing is voice calls i still don't see how good and different 3g is from 2g "it's not like you are recording an album over the phone to need such voice clarity" remember a good battery life affects your phones performance in a great way. these photos tell the whole story..

i used the wi-fi for about 12 hours and when i switched to 3g it drained in 2 hours
For screen brightness you will notice that every time you check battery usage your screen always has the biggest share of the consumption. You have to reduce your screen brightness to 30% or lower or put it on auto-brightness that's about all you can do about it.
Also your rom and the kernel it comes with are a huge factor in battery consumption. On a general scale i have noticed that sense roms are the big killers of all just see
in 51 mins of no use at all just screen off the battery drops to 81% i have never had above 9 hours of use with any sense rom
Other things like gps also drain your battery, so if you are not on "MAPS" just switch it off to save your battery. Also keeping your cpu clock speed at high points drain the battery a lot try to use apps like setcpu to control the clock speed and set profile like screen off to keep your cpu down when you are not using it, and use cpu governors like smatass, ondemand, conservative etc
Also the trick of draining your battery completely and then recharging it in intervals of 3 months or more help enhance battery life,
do not leave lots of apps running in the back ground they also drain you battery alot :good:
Any body who knows something that can help pls add cos there are a lot of guys who still don't know these stuff....
and a lot of guys like me who still want to enjoy their G2 for a looooong time....so big boys...yes it's needed......
photos missing.......................................................................................................
About the sense roms, even though i agree it consumes more battery than AOSP, they are not as bad as u say (at least not all of them). I use a sense 3.5 rom and with regular use i get about a day and a half before it hits 20% (80% consumed) (This is on 2g, with wifi on... when with data on, i still get at least 22 hours). I know it comes down to settings and usage, but just saying, its possible to get a lot of battery endurance with sense.
If anyone is interested in more detalied information on my settings and usage, feel free to ask me (through pm if possible)
Nice review though, thanks for sharing!

This is impossible if you havent got a problem with the rom. I have been using all kinds of roms with my Desire Z. The battery life is not that much different on sense and aosp roms.
I am using GenY Beta5 right now for example. On standby mode (only gps is disabled) it can go more than 2 days! A stock optimized 2.1 Sense rom can go even more than that.
For battery life problems I suggest using an app like Better Battery Stats and see what is causing your phone to stay awake. It is easy to see what eats your battery.
Other than that as you said, whatever rom you use Screen will eat your battery the most. Overclocking will obviously eat more battery too. Using 3G instead of 2G will use more battery. COnstant Wi-fi activity and gps are battery killers too as you may guess.
The rest is how the user uses his/her phone.

All you are saying are basic stuff everyone knows about power consumption, and all that you have been testing are YOUR results, what you are saying now are absolutely no facts, and some are wrong. You're saying sense takes more juice? Well since IceCreamSandwich it doesn't really matter. Are you sure your battery is properly calibrated?
After installing a rom you shouldn't put the phone on a charger, but just use/leave it till the battery has 10% left. then charge till its full. By prefer you should do it another time and then it should be calibrated.
Also you forgot to add the radio. The radio is also important, if you got a proper radio for your provider/rom, you can easily get more power out of your phone. If you have the wrong one, drains can be high. The extremest example I can take is my old HD2. Which had a radio not compatible with the version of android and the battery drained from 100 - 10 in 3 hours.
Now look at my stats of my DesireZ, running Gen.Y RC1(Which seems to be using more battery then the B5). I attached a screenshot. The battery is totally stock and not an extended one. I used it yesterday at home when I was busy with my car(whatsapp, mail, google), at the evening I played some games. Before I went to bed my battery stats was 60%, when I got out of bed this morning it was 59%.
Also I think the topic should be in "general" since its talking about everything, and I can't see how this is rom development.
Thanks for adding up guys,but I am sure your batteries are quite fresh that's why you have very good batteries,people like me with aging ones who still want to use it for a while. I had to wipe my battery stats a few times to calibrate it. And if your read things very well this was meant for guys who really don't know the does and donts about battery usage yes it's basic but people still ask these questions in dev sections. I did not add radio because that thing does not work well for everyone and it's still an easy way to brick your phone most of these radios were made with USA service providers in mind ,people have complained about having serious issues with battery and connectivity when they Change their radio and if any one is even reading this then I don't think that person even knows what the radio is so why not do the basics than brick your phone in an attempt to go high .....to the big boys who know all.... you have to know that there are still guys out there without rooted phones facing these problems so radio is the last option......

If their phone is not rooted, how can they have a custom rom then lol. I think if you want to use a custom rom on your phone you should read everything and not blindly start everything. Also flashing a radio has risks, but not really something to worry about if you do it right. Its quite easy and as long as you stay on the right path you are fine. If you want to make a proper thread about battery consumption you should include the radio thing. And also post it in a place where it belongs. You are right that newbies don't know everything, but if we should do everything for them, you get even more newbie questions. They need to put some effort in it like we do.
also you have not added the tricks like changing the advanced wifi to always wifi when screen off....

A long time ago in a galaxy far, far away...
Recently i installed ICJ. Since my Battery started decreasing quiet fast, i remembered a guide from the good old Desire days. It was a really good, indepth view on how to determin
what burns your Battery and how to set up your phone perfectly.
In the last view days i tried applying some of these tips and found them more or less usefull.
Since HOX is a Tegra device some things are handled differently. So i thought it might be time to update this a bit and let you participate in my hunt for the best battery performance.
First of: I couldn't find the original guide. So no link here (sorry). I will correct this if i find the right thread. This is all my own work! I don't use any part of another post.
By now this is nowhere near complete, but i'm constantly adding. If you wan't to contribute, PM me and i will consider adding your content (with credit ofc).
Since a lot of testing and time intensive tasks are included here, it may take some time to come to some "final" results. Please bare with me because my phone is my daily driver to.
Introduction
To final start of, i think i should determin the goal of this guide. I hope that this will grow to be a reference for general Powersaving on HOX and finding what is wrong (or could
be improved) with your phone. To be clear:
This is not done in 10 minutes! You need time to test different things.So you won't be able to read a short post, change three settings, deinstall an app and double your Batterylife! Period! This is a approach of finetuning and getting the most
out of your phone. I don't want 24h Battery life with a laggy non useable phone. which leads to:
Setting your goals
It is crucial to determin what you expect from your phone. Remember: this is a quadcore phone with high-end-graphics. You won't be playing Shadowgun and get 10h of "Playtime"
My personal goals are as following
I plug of charger at 05:10 and come back home around 19:00. I would like to have 15% left when coming home (already done with ARHD)
Usage per day:
3h Music
4h forum reading
some browsing and reading webpages
4-5 phonecalls
a bit of texting (SMS/What'sApp)
a bit of playing with settings and homescreen settings
nearly no gaming and if so then no tegra games
a bit of lag is no problem, but i don't want to wait for my phone to load anything
flawless music playback while screen off
Video playback up to 1080p
no Radio issues (to low voltages can make radio instable at times...)
So all in all no great things, but i'm using my phone a lot and have high screen on times. But i'm not pushing the tegra chip to it's limits (not nearly ) I think my goal is
realistic. Remember that your goal should be doable. Just think of what you expect, and you will see relativly fast what can be done and what can't. So what are we working wwith?
My Setup
Just to give you some insight, and to make values comparable, i give you all the relevant information about my setup. You might skip this paragraph if you're just after the tools
and techniques.
My Phone
HTC One X (Obviously)
Black one
Vodaphone Germany Branded
not on JB hBoot
Unlocked
TWRP
No obvious Hardware faults
I got mine relatively early and have one of the first badges...
My Software
atm (16.10.12) IceColdJelly 3.0
Android 4.1.2
Nova Launcher (No theme)
BB10 Lockscreen Mod
NCX Kernel (comes with ICJ)
Apps (most recent used, Basic Setup. The Core i use. Others come and go ):
Airdroid
DB Navigator
ES Explorer
Noom
S-Finanzstatus
Tapatalk
Titanium Backup
YouTube
Gapps 20120726
Rest is stock and preinstalled
Other things relevant
I Use HTC standard charger with original HTC USB-Cable
most of the time i don't use a case, nut now and then i have a HTC Flipcase installed
No other accesoirs (No Bluetooth things, no BlingBling or dock or anything like this!)
...
General idea
The idea is, to determin how much current is drawn on a fresh install without apps and only google account entered. After that i want to determin what apps/accounts/settings draw
how much power. I will start from my current setup (see above) and not with a clean install. Reason for that is, that i want to give you a guideline to follow. I think most of
you have your phone setup ready and need more batterytime now.
Atm i'm not on Sense and until there is no universal JB Sense for all CID's i won't go back. So right now, you Sense user might be able to follow parts of this guide but settings
may vary. So you might have to get your head around that for yourself.
Preparation
No, finaly, we dive into geting our hands dirty.
You will need some tools and apps to measure different things. I highly recommend using the apps i use, because they are on the market for a long time, they don't draw aditional
power while in background and i use them for nearly 4 years now without problems. Also no adds, which is great because adds are one of the things that rape your battery like mad!
Things you'll need
A wallcharger (USB on a PC will work, but increases the time you need for this process alot)
Apps
BetterBatteryStats (free Version on XDA. Link will be added later)
CPU Spy
Current Widget
What the apps are for
BetterBatteryStats gives you an overview of what is using your Battery/CPU. Not as clearly labeld as the System option, but much more in depth and highly usefull to
determin which part of certain apps draw your power. Also you can see if your phone goes to deepsleep.
CPU Spy lists all CPU Frequency steps and how long they have been used. Again, seeing if your devices goes to deepsleep and if an app keeps using the CPU more
then it should be.
Current Widget is probably the most usefull app to date. It shows how much current is drawn from your Battery and writes it into a log. So you can directly see
if a change affected your Batterytime. And you don't have to have your screen on to measure (great plus here )
Reseting battery stats
To start of clean i highly recommend wiping your battery stats. Do do this, fully charge your phone (100% and then wait till charging light goes green, but minimum 30 min).
plug of charger and shutdown your phone. Replug charger and again wait till charging light goes green. Plug of charger and reboot phone. Now your Battery history should
be clear and we're good to go.
The rest follows as i proceed. I'm currently in the process of investigating and testing on my phone. If you think this guide might help you or others, give a thanks.
If something like this is already done stop me now, before i spend 100h writing this Suggestions or tips for improvement are welcome and highly appreciated. If i made a mistake or have given wrong information, tell me and i'll correct asap.
Please bare with my english and my spelling since i'm from germany and english is not my primary language.
Other than that, bye for now. Enjoy reading.
Thanks to all XDA-Members, Devs and Content creators. I've had 4 awesome years in this forum till now and enjoy giving back a bit to the community.

One spare
And another one (have something in mind for this one )
I'm going to keep my eye on this thread for any unexpected results – I get the feeling it's not going to be this or that etc. I might start using JuiceDefender again, quite an innovative app. Either that or just switch to 2g periodically.

It's not about finding the one app that eats up all our batterylife. It's more of a guideline to determin which specific apps and habbits burn your battery.
For me Juice Defender always used more battery running in background than it saved, but it's up to you to test it, and give me some feedback. Surprise me and i'll add it to the guide

Sorry I missed that point – it's to discover your own personal usuage habits that tie in with (excessive) battery drain. If you want me to run it seperately as like, a comparison then yeah of course. I will reset my battery stats and use JuiceDefender. For how long though?

I think 1 hour of the same activity should be enough to determin a percentage of gain or loss in batterylife.
Well, I have recently installed a new ROM (ViperX) and installed Google Now which has battery drain issues. In the hour tested I've received 10 emails, four texts (sent three) two facebook notifications, downloaded a 4mb app and listened to approximately 16 mins worth of music. I suppose that counts as moderate to high usage. With Juice Defender I am on 89% I was loosing much more than 10% per hour before now.
Hopefully this helps?
Yeah, I have a drainage of 547mA after fresh reboot which is crazy... Google location service is one of the suspects. I'm investigating in that now, which would respond to you saying Google now is draining. I dropped 10% in 3h of screen off which would mean 30h of standby. Sounds somewhat low to me.
I'm in the testing today, and tomorrow I will write part two. Let's see what's to find there...
One thing. What settings did you use with juice defender?

Just had it on 'Balanced' – there is a fix for the battery drain issue with Google Now combined with Sense roms. But the apk decompiling process is a little out of my comfort zone!

Good luck with this man. I was thinking of doing something like this once Faux's kernel 12 comes out of beta, but I don't think I need to anymore
ATM I'm struggling to get consistend results. I have hours where my battery is sucked with over 600 mA idle. And then everything is fine with around 190 mA. All without changes in the last days. Really strange...
Gesendet von meinem HTC One X mit Tapatalk 2
190mA is really high for idle
I just installed Current Widget, it doesn't seem to record idle screen-off usage. Battery Monitor Widget is waaay better for recording mAh used. Even works with screen off.
I've had the Galaxy Nexus LTE for nearly 11 months on Verizon. I've done what I can to stem battery drain. At some point, I just gave up diagnosing the problem and started carrying 5-6 spare batteries with me. Some people claim one day's use; others report the same problems. I think it all depends on how we use our phones--eg do you take a lot of pictures--and what apps we have installed. I use the phone hard but not that hard. Sometimes the phone will burn the battery just being in the pocket.
I don't want this to be another Galaxy Nexus battery life sucks thread. What I want to know is whether the battery drain problem will be solved before we consider moving onto phones running 4.2.
Some of the drain is due to the terrible LTE radio. Phones with integrated chips have much less hardware drain.
But about the software drain? When I run GSam Battery Monitor, the number culprits seem to be Media Scanner (Server?), acore processes--contacts, user dictionary.
I've dialed down or turned off syncs as far as I reasonably can; are rogue apps causing problems or is the OS too easy to trip up?
If you search http://code.google.com/p/android/issues/list for "media battery," you see a lot of bug reports about the problem.
The Google Android team doesn't seem to care about these problems.
http://code.google.com/p/android/issues/detail?id=11731#c5
"I'm only posting this here for my own amusement. My track record with Android bug reports is that Google ignores them for 2 years and then closes them without taking any corrective action. Good luck everyone."
Here's a typical bug report from mid-2011, that is still labeled new and unassigned:
http://code.google.com/p/android/issues/detail?id=18115
4.1.2 has the os drain:
http://code.google.com/p/android/issues/detail?id=38720
Going into 4.2, how do we track these issues and see if they are getting fixed? I'm not a dev... The only way we can see the 4.2 source and commits is to clone the repo using git? Is there a friendly web interact through which we can see the changes?
Do we wait until 4.2 is released and see what defects are reported on the issue tracker?
Please don't let this be a typical battery life sucks thread, where people will
1) complain that they also have bad battery life
2) complaint that they have great battery life and don't see these problems
3) suggest debugging these problems with CPU SPY, BetterBatteryStats, etc
4) suggest fixing these problems with .nomedia
I want to know how we as users can track what Google is doing or has done to fix these problems in 4.2, so we, as Android devotees, can have faith in migrating to those devices.

Any Tom, ****, or Harry can post issues. Most of the time they don't have the technical knowledge to even know what a bug is. Don't confuse Google not caring vs. Google not willing to accept a ticket caused by something out of their control.
As for your case, you have a Verizon Nexus. They ALL suck on battery compared to other devices.
You say you don't want this to devolve into a typical battery thread but it will.

no lte in the nexus 4, sounds like they chased off the battery sucker to me.
I'd you're using your phone as a laptop, it's time to buy a laptop. Otherwise, the turn if syncing for things you use once a day. Actively using data (especially over LTE) with a large screen burns battery on any device. If you are burning battery in your pocket, you either need to sync less or identify the rogue app that is doing the work. And Google does use the bug reports to make improvements. A recent bug in Chrome removed names from the shortcuts in the bookmarks bar and it was fixed within a week. Android rakes longer due to the wide spectrum of devices and overall update process. Bugs in an OS are a different beast than bugs in a browser.
From the sounds of things, you will have battery issues on any device.

Go by the evidence. The Media Server / Scanner drain problem still exists in 4.1.2
Complaining about battery life on an LTE device is like dropping a 600HP engine in your car and complaining about your gas mileage going down.
So lets say an LTE phone has an enormous battery in it, this might give you "respectable" battery life... but take that same huge battery and put it in a GSM phone and watch the battery life go from "respectable" to "incredible".
If battery life is what you need... you might consider going GSM. With heavy use I usually end up at about 30-40% at the end of the day...
Of course, as stated above, the media scanner bug is still there... but from my experience, LTE is the biggest "battery vampire" by a landslide.
I can't wait to see how many "battery life sucks on N4" threads are created.

Oh it's coming... It's coming... Best believe it! Lol.
Honestly, it's just the way it is so ppl need to get over it. If they buy the Nexus and complain about the non-removable battery, then they should have gotten a different phone instead. Like an S3.

That's 4 days of actual on time (I turn it off at night, ~15 hours a day). That's closing in on what my old Nokia and Sony feature phones clocked in at.

First, turning it off at night, makes your "4 days" statement entirely false, automatically. Second, 1 hour 20 minutes screen on time is terrible, even for a known battery sucker like the gnex. Third, the only thing might slightly warrant a pardon for that screen on time, would be the fact that you did get over 2 days on it, if not for Fourth (and finally) the fact that your phone clearly shows that your didn't use it at all.

4 days of my use, where is there false information? Still on the same charge, 1 hour 41 mins now. 61 hours with real world use is not bad, especially since despite you seemingly knowing how I use my phone, I was using it for texting, a few calls, I used google maps, updated some stuff and other random crap. A lot can be done in an hour and a half.
And finally, the entire point of this thread is the android process sucking up battery, which is why I posted a picture showing the contrary. How about you find something credible to ***** about.
Maybe if you stop using that ugly, bloated, stupid ROM your Android process usage will be reduced.
