It doesn't get better...get used to it until its fixed in an update , along with the other big issues.

By about the 3rd day it seemed better. But it's also difficult to gauge because the first few days you're bound to toy with it constantly.
Until there is an empirical way to gauge usage, like an amp meter attached to the phone - it's all perception imo.

Do yourself a favor and try aokp milestone 1 from rootzwiki , and also download lean kernel 1.1.1 on xda. Use interactiveX governor for kernel. This is the exact setup I am using now, and have been for a few days and have been getting insane battery life. Hope everything works for you.

You really have no idea what you're talking about. First of all, it will get better, I won't bother explaining the science behind it considering you can do your own research, but it will, also, it can't be "fixed." Just like they can't make it an 8 mega pixel camera in an OTA. You can get it much better by doing custom roms and thigns of that nature.

It got better when I turned off vzw backup and google +.
Best I got is 16 hours bone stock just an extended battery. Worst I got was 4 hours(screen was on the whole time) watched 2 movies before I plugged in. I average around 12 hours from 100% to 20%.

First off, it's hard to tell by your screenshot how good or bad your battery life is. You're burning approximately 10%/hr, but maybe you had your screen on or were surfing the internet for a portion of that time. Anything that involves data transfer will kill your battery faster.
I got my Galaxy Nexus on Wednesday, and I've had great battery from the start. I calibrated it by letting the phone's initial charge die down to zero, and then charged it all the way up to 100%, and then used the Battery Calibration tool. I drain between 2-3% hour with light use, but can obviously drain much more depending on what I'm using the phone for.
That being said, for those on this board who think an OS upgrade is going to fix the problem, I highly doubt it. I have a reasonably poor cell signal (averages around -95 dbm), but still get solid battery life. Given that we were all issued phones with the same software, if you're experiencing incredibly bad battery life, I'm going to point my finger at the hardware. It just doesn't make sense that some of us with 4.0.2 get great battery life, and others do not. You probably have either a bad battery or a bad phone. Now, I'll probably get called out for saying this, but watch all the posts that follow when the update releases, when people still have poor battery life.
This is my 3rd Android phone (Incredible, Charge, GN), and every one of these phones has had poor battery life. On average, if I'm playing around with the screen on, I'm draining upwards of 10%/hr, if not more. But if you properly calibrate the battery - which is VERY important - you should easily be able to get a full day's charge out of your phone.
There is a post on XDA about the 13 steps to proper battery calibration. Once I followed it on my last phone, my battery life went up at least 50%. You have to let the battery drain to 100%, then bump charge a number of times, then use the battery calibrator.

Try running without JuiceDefender. Constantly toggling data on and off (or wifi on and off) actually hurts battery in almost all cases.

Your results may vary, but when I used Juice Defender or Green Power on my Droid Charge, I nearly doubled the battery life. I haven't put it on my GN yet because my battery life is much better than what I had with the Charge.
No using JD or anything like that. Just the the phone do its thing. I don't even open the multitask button unless I want to switch between apps.

Gotta be a software issue with the battery.
Just this past weekend in Wash DC. Very strong 4 G market.
I had it fully charged off charger. After 7 hours without touching the phone even with google plus sign out, the battery went from 100% to 54%. It's like the phone was active a lot without me even touching it. No SMS/mms either. No emails either.
Know. I did same thing and put it on airplane mode with it 100% charged. After 7 hours on airplane mode it was at 98%.
So it's gotta be an operating system issue.
I tried it on wifi instead of 4G mode. And battery drainage was down to 72% after no use overnight.

Out of interest, how many times have you charged your phone (0%-100%)?
Never drained it to zero and started using it right away without charging it. Its been charged to 100 twice already. My uptime is 73 hours and that's exactly how long I've had the phone.

Honest question, how many times are you more than 12 hours from sleeping or relaxing in your house?
12 hours is more than adequate for a normal user
This is mine after a fresh wipe and no apps installed. Just thought i`d see how it did with normal use.
Here's mine; at a point the phone got itself shut down for some reason, and I couldnt get it restarted at that moment, so I left it like that, and when I could turn it back on, it was quite warm around the camera unit, and also the battery was pretty much drained - thats what you can also see on the screenshot at the "20minutes" part of t he scale. After I've removed the battery and put it back, the phone was working for quite a while again, like 12 more hours.
I'm sure auto brightness helps as it keeps screen dim but during my use it was brighter especially outdoors. My whole point is there is no secret, you should use the phone as you would like it. One thing I could have done I'm sure to improve battery life is turn off wifi and bt when they weren't in use and possibly not have as many apps running but then what's the point in having the phone?: D

I get around 11-13 hours. Not too impressed. My iPhone 4S gets 20 easily. I'm really conservative on my Nexus too because doing anything intensive (games, video recording, youtube etc) really rapes the battery. I'm guessing some of you turn off auto sync or something.

It's simple really - the more you use the phone the worse battery life is but that's because you used the phone more! I never use the phone LESS just for battery life because then you're doing yourself and the phone injustice.

So JuiceDefender works fine for you? I just read that alot of users had problems with ICS and JD. Would be great if it worked though!
Here's mine. Since I was at work all day I only got time to play Dillo Hills for about 20 mins but I've found the battery is REALLY good after flashing the Android Revolution ROM. MoDaCo causes too much drain IMHO.
Battery life isn't too bad on mine. I got mine on the 10th and I used it right out of the box. Battery life wasn't that great until I did a charge to 100%. The OTA update didn't change much for me in regards to battery. Currently at 21h uptime and I'm at 32%.
Hey all, I'm looking for some advice regarding the battery on my Verizon Nexus and I wanted to see if anyone else was having troubles too. It seems as though my battery is discharging very very quickly to the point of where I'll pull it off the charger at 100% and within 10 minutes I'm down to 90% with little to no usage. Again, this is the stock battery on the Verizon Nexus. Thanks all!

Stock ROM/Kernel? Try changing, see if the drainage issue changes. Even reflashing an updated stock image may help.
It looks like the problem is the screen using up the battery. Its using 66% of the battery right now and I'm down to 88% battery after about 25 minutes with brightness on 10%.
Sent from my Galaxy Nexus using Tapatalk
That's standard behavior for most phones. It damages the battery's long-term life to keep it charged to 100% for extended periods of time. It actually trickles down to 90% while on the charger after reaching 100%, but doesn't actually tell you so, because people would get confused if their phone sat at 90% while on the charger.
Lots of laptops do the same thing. E.g. my thinkpad never charges to more than 94-96%. Standard behavior to maintain the battery. The computer is just up front about it, and the phones do it more sneakily.

I had the same problem the first two days of owning the Nexus. I would go to work at 6am and the battery would be drained by 12. I did a few things that seemed to help.
1. Disabled 4G LTE
- My area is spotty when it comes to 4G, so the phone constantly searched for it.
2. Lowered Screen Resolution to 10%
3. Used a dark background.
- The screen will use less power if the background is dark (black is best)
Doing those three things made my phone last from 6am to 6:30pm, which is a noticeable improvement. This was done using the stock battery. I did order an Extended battery, but I have not received it yet.

My battery also drains very fast. I'm at 48% with screen using 33% and android os using 31%. My screen on time is only 58 minutes but android os has kept the device awake for over 2.5 hours
I have a Galaxy Nexus, I had a Droid Incredible 2 before that, and a Droid Incredible 1 before that, and *all* of them have exhibited this behavior.
My nexus was in and out of 4g tonight and I'm at 35% with 9 hours on battery. Used a lot of Google music in the car. FWIW I'm using set CPU . That's probably helping a bit.

Lithium Ion cells do not get better in any way after a few charges.
In fact the capacity goes down a wee tiny little bit with each and every charge, so your first charge was the "best" one.
Stop playing around with the thing for 5 hours non stop and you will get decent runtime.
Best thing to do with a new device is to charge it up fully as soon as you can. Then run it down until you get the low battery warning. Then charge it back up.
Battery life will likely be pretty poor for the first week or so, then it will normalize.
Deep discharging (to 0%) is about the worst thing you can do to a LiIon battery, because it "hurts" it much more than several shallow discharges.
Also, like I said before, battery capacity won't in any way rise or "normalize" over the first week.
Battery life is poor the first days because you use your shiny new device all the time (i.e. more than later). It's like that for all of us.
My battery life sucked the first few days, It got better though. It really only seems to suck it down if it is hunting for a signal constantly.

You also need to try this manual battery calibration:
http://myhtcdesire.com/tutorials/how-to-improve-your-battery-life-calibration-tutorial
After I did this, saw the battery reading 99% and 98% more often rather than straight to 96% after charged.
Originally, it was suggested by HTC tech support. I did that once every six months or so ... And my battery level is now improved. Screenshots will follow in the next post.
Not bad?
Sync is off btw. And this includes using Maps 2%.
At least with my usage pattern, I am more or less satisfied.

You need to remember the only thing relating to battery life is not just the battery, it's software as well, hence calibration. After about a week or so your phone gets a "feel" for your battery and gets more battery stats, so it's more accurate with it's readings. That is a proven fact, you need to think about all things.

It is quite easy to gauge a Lithium Ion battery. 4.20 V = full. 3.60 V = empty. Your phone can read the battery precise to 0.001 V. The curve isn't linear, but it's well known what voltage relates to the exact capacity left in the battery.
There's really no room to "feel" anything there, just simple math.

I consistently get 15-18 hours of use out of mine with the extended battery.
But to the OP, if your screen is taking up 60% of your battery, it's always on, your battery is gonna die, it happens. Your battery doesn't get "better" with time. It seems that way because you aren't glued to the device 24/7.
Mine was god awful when I first got it but after a week or so it got much, much better.
I have the GSM version though.

You do know to "remove bloat" all you had to do was go into the stock app manager in settings and disable anything you didn't want. That is actually a much better solution than "freezing" with TiBu or removing altogether. I'm not convinced root and mods are 100% stable yet. Most people reporting decreased battery life are those that have rooted or modded something. I'm still 100% stock with ATT stuff disabled and batt life is still 7+ hours.

Even bare stock I wasn't getting that much screen on time. So far I've only rooted and changed the kernel. Though today my battery life is starting off good. Yesterday I ticked the power saving option for the screen. I'll post an update tomorrow.
Today I was on for 5.5 hours, screen time of 2.2 and was at 54% with Power Saving On
So I went to bell and grabbed another battery
Time will tell if that helps
I could never reach 5 hours of screen time but could have the phone on for 30+ hours
I cant wait till we get more developer support, I used Francos Kernel with my galaxy nexus and it improved battery by 30 % and made my 8 hours overnight use only 2% battery. I was using 12-17% overnight with my note 2 asleep. Aside from kernels and roms I use this phone exactly the same as I did my Nexus. wifi off, bt off, gps on, push email on, auto brightness

Lithium Ion batteries actually do better if you don't charge it constantly. In other words let it run down a bit before charging. You don't want to always keep "topping it off". But in general these batteries are much more resilient than others.
Just do some research. There's lots of info out there.

Umm, no, it does not. You are stressing the battery out. Unless needed, dont keep the battery below 20%. Its healthier to charge the phone sporatically throughout the day.

Agreed. Full discharges are not necessary for lithium ion batteries. Full discharges were needed for NiCad or NiMH batteries as they suffered from memory effect. LithIon doesn't suffer from this. With that said, a lot of experts do suggest discharging a LithIon periodically, maybe once a month or every other month.
I'm not complaining about battery life bit I just fond this strange how with nothing running my phone went from 20% to dead that fast. Phone was locked and in my pocket. Anyone have any ideas? It's also not the first time this has happened either just the first time I thought to get a screen shot of battery usage right after
**Update**
Now my phone is dying at random :/ it does it from 50%, 30% etc. Any suggestions (i.e. battery calibration, full factory reset) or should I make it stock again and get a replacement?

Batteries are gauged by how much voltage they are pushing in most tests. Though from my hobbies of electric rc cars, I've learned that batteries can change their voltages simply from a temperature change. While these changes may not be significant, they do represent differences and used to play a big part in my fifteen minutes charge cycles. It's harder to receive a positive rating in a cell that is low on power than it is with one on max charge. So if I'm down to twenty percent or so, I use my phone very sparingly. Has been pretty trustworthy for me over the years.
Either way, suspicious battery drain is usually a rogue application sitting there eating resources as the phones we use do seem to monitor battery life pretty good compared to the old voltage meter methods.

Could be completely of base, but I know the htc loaded Facebook is slightly different.

charge it to 100 then bring it to down to 0. then back to 100 and youll probably be fine

I'm not complaining about battery life bit I just fond this strange how with nothing running my phone went from 20% to dead that fast. Phone was locked and in my pocket. Anyone have any ideas? It's also not the first time this has happened either just the first time I thought to get a screen shot of battery usage right after
**Update**
Now my phone is dying at random :/ it does it from 50%, 30% etc. Any suggestions (i.e. battery calibration, full factory reset) or should I make it stock again and get a replacement?

I assume you had a good signal everywhere you went? Nothing drains a battery faster than being in an area where there is very low or no signal. It constantly tries to connect and it will KILL your levels very fast. I see this quite a bit in my work place. Employees with Sprint and many times AT&T will complain about their battery dying at work only to find out the phone was constantly searching for a signal.

You know, I totally forgot about that. I used to have that issue with Sprint myself. Killing the data would eliminate TONS of battery usage when I was at work. Now that I'm on Verizon, there's never much problem. But he's completely right. If you're not getting a quality signal your phone may be searching and that can be an all day thing which just eats a battery alive.
I am in a near perfect signal. I'm pretty sure its has nothing to do with coverage. What's strange to me is the phone immediately dies. It will be at 50% and then the screen goes black and won't come back on. Once I plug it in the phone finally comes back on and is at zero.

Exchange it. My first One had weird reboot issues. It might a bad phone.

And another. Phone was right around 50% and then bam off

The battery is obviously defective. You need to get a replacement.

Alright. Time to start the relock process :/
Thanks for the help everyone

I'd have to search around, but taking these batteries all the way down actually reduces their effective life.

Basically, the more you drain the power before charging, the less charge cycles the battery will have. Someone who charges at 75% compared to someone who charges at 25% will have more cycles over the life of the battery. I can't remember the exact numbers, but there's been plenty of studies on the issue. And if I'm correct charging at those numbers, the 75% will have more than twice the charge cycles over the life of the battery. The biggest battery killers though are actually higher amperage charges. One study showed more than five times the life cycle at 3.7v per cell compared to 4.3v. And the charging required to power the higher voltages actually cause more damage over time than the extra mah output is worth. The HTC one has a decent setup and the stock charger doesn't over feed the cells. But in not sure if it will make it to the 700 charge cycle that a two year contract may leave a user with.
