Galaxy Nexus Battery Life

I have been having bad battery life for my Galaxy Nexus. I got an extended battery and it helps a bit. Any suggestions on how to extend battery life.

You should give us some details on your usage. How about some screenshots of your battery stats page after a full days use?

install betterbatterystats as it can help you find what's hogging your battery. It's on play store but also available for free for xda people. Google it and the free version should be the first link.

i hope you are not using stock kernel ... sometimes it helps alot to change it (to replace stock kernel).. i haven't tried on my galaxy nexus yet .. but on my htc wildfire .. it was clearly noticeable ...

Franco kernel, it takes very much longer battery life.
There are also programs like Jucie Defender, ...
Often there is a program that takes a lot of power, just look under "Battery" ...

Stock kernel is fine. I get 4½ hours display time with auto sync with auto brightness on rooted stock 4.1.1. I got the same using various kernel/ROM combos on ICS. So no, there's nothing wrong with stock kernel.
Did I mention that's in a 20 hour day with stock battery!? And there's already like 20 of these threads.

Yes, in 4.1.1 the battery consumption is much less.
Easy 24 hours on one battery charge ...

Jelly Bean battery life is awful

Which ROM are you running? I'm using ViciousV5 and the battery life is awful, I have a 3800ma battery but I really need a car battery with this ROM. On 4.0.4 the phone would run for 30 hours, now it's good for 10 hours.

Post your tips for battery life.

Most people in this forum are far more tech savy when it comes to cell phones.
Post your personal tips for battery conservation. Include specific apps if you'd like.

I don't worry about battery life, brightness all the way up, sync on, widgets on every screen, Wi-Fi always on. I usually get about 14 hours

I'm very conservative. WiFi off, data off when not using it, brightness depends, auto sync off, no battery sucking apps like facebook

I get phenomenal battery life out of my S3 (stock).
I had an Epic 4G and was afraid to leave my desk because of the battery drain. With moderate usage (30-60 mins talk time, texting, chat, some web, exchange, ect) I can easily get 16-20 hours. Signal quality in your area will impact it more than anything. Also, wifi is vastly easier on the battery.
PS Facebook app SUCKS. Just bookmark the webpage and use that. Works better and doesn't ruin your phone.

Here how it looks like ! Lovin this screen on time..

I think it depends on how its configured. I've seen it eat the battery but also not use it much at all. Been a bit since I messed with it though so don't remember what settings made the difference.

i have betterbatterystats too but have no idea what the wakelocks affect and how to get rid of them.

Post a screen shot and I'll tell ya what could be happening.

You can improve battery life by switching to custom roms with less bloatware, and updating to more efficient kernels. (This is on a Rom/Kernel level)
Software wise, just figure out what apps are causing wake times and try not to use them. Basically whenever an app/widget refreshes/updates content, it may cause phone to wake (like weather/clock widgets for example).

I have been using cpusleep and it seems to have helped my battery life ... also using a custom rom without the bloatware is key for me.
my current setup is freegs3 release 6 with the latest trinity kernel...even though its overclocked my battery has been amazing and phone has worked flawless.
Im also using system tuner which has given me the ability to manage the cpu with on demand and other customizable settings
The only thing I synch is my k9 mail account
I also have frozen several samsung apps which helped...
Im now getting over 20 hours of basic use between charges...I dont use games/videos so might be a little skewed . I use this phone for business calls/internet/messaging/photos/navi...pretty basic

4500mah stock

I have been using Gigajoule lately by feckmu and it has given me the best battery life out of all the custom roms I have tried. Even with GPS, WIFI, and screen at full brightness I can make it through the entire day with 30-40% battery left. If your looking for a rom-based solution to your battery life, check it out!

The latest version implemented fast charge something to try.
If you just flashed it you will go through your battery considerably faster until you do a full charge.
Besides battery usage is dependant on each phone and individual user.

What sort of battery drain are you seeing? Curious as I used to use Task's ROM as well and never did get the same battery life as others were reporting...I know everyone uses their phones differently and have different app, but even with limited apps and usage, never really got great battery life.

Ok so far i have left the wifi and internet off and the battery is hardly at 80% since 8am. Huge difference!
But as soon as I turn it on either 4g or wifi it drains very quick.

4G is one of the known biggest battery drainers. This isn't just for my rom. It's for all roms on all devices. Battery life is also users dependent. There are so many variables like location, apps, settings, the way you use your phone, ect... the list can go on and on. With that said. I always get around 22-25 hours and 3-4 hours screen on time on a single charge. That can vary depending upon my usage.

3 reasons: You either have Google Now setup, You sync too much stuff and/or you have location access/GPS turned on.
And as Task mentioned, 4G is a big battery drain. If you feel it's too high, drop to 3G/H while you don't need high internet speed.

Ok I checked and I made sure to always kill all running apps.
Definitely the wifi and the 4g drain battery to quick, very quick.
But what really pisses me more than all is how slow it takes to recharge...
I tried FAST CHARGE but all that do is to charge from usb ports like if it was your wall electricity socket.
The only option i have left is the Kernel you guys keep suggesting.

Solved the problem at least for charging.
I bought an used Galaxy s3 and apparently the guy kept the original charger or lost it and the one I was using wasn't good at all.
So I had another charger of the HTC one x and this one works perfectly!
But still, now I need to find out why it drains battery so quick when I'm on wither 4g or wifi.
Does the Kernel do that much difference?
Well if that is a yes then I have a few questions:
Do I have to wipe my memory so I must do another back up?
Will this Kernel be compatible with Galaxy s3 i747?
Any step by step guide that I can do this easily without any warning or danger?
Link please?
Thanks.

All you need to do is read the OP of the kernel thread that you want to flash. That would be your step by step. 4G will always be a battery drainer. There's nothing you can do about it.

I also run task 650 but I don't believe that the slow charge is ROM related. My phone seems to take forever to charge since I upgraded to jb. I'm thinking there was an issue with my battery because my wife's gs3 charges much faster. Only way I was able to work around this was to charge while powered off. This happened on every ROM I have flashed in the last couple of months whether aosp or twiz.

[Q] Batter draining too fast..

Just got a replacement Epic from Sprint about a day ago. Looks new, probably refurbished. They replaced my old one because it started having some problems along with fast battery drain and inconsistent battery level readings on the device.
So I have my new device along with a new battery from sprint, and I thought all would be well but my new epic and new batter is still draining about 10% every 20 minutes with light use (internet browsing over wifi w/ lowest screen brightness setting). Also, when the phone gets to about 30 or so percent battery life it starts lagging and when I pull the battery or reboot it, the batter meter will read real low (like under 10%) once it powers back up.
I am rooted, I installed The Peoples Rom all according to the instructions from qbking77 on youtube just as I had with my last phone without problem.
I have calibrated the battery twice, and wiped the battery stats in recovery.
I was having these same problems with my last epic which is why I had it replaced. Now I have a new one and new battery and the same problems. How can I fix it?

Also not using GPS, Bluetooth, etc
Just wifi and web

Sounds like an application you are installing is the culprit. Search XDA for "better battery stats" and download/install that application. It will tell you what wakelock is your problem.
Wiping battery stats has been stated to do nothing to benefit the phone/battery/user. It's a placebo. (http://www.androidcentral.com/wiping-battery-stats-doesnt-improve-battery-life-says-google-engineer)

GPS and Bluetooth being enabled is fine. They remain inactive until a process calls that action; such as opening Facebook or Maps.

Play with the settings in the middle and last drop down menus to pick a duration of time and then toggle the top menu to see what's keeping your phone awake. usually "partial wakelocks".
Also, if you have a virgin install, then you can very well have a battery on its' last leg. We have an old phone, so it is very possible you have an old battery. Yes, even from Sprint.
If you don't see any outliers in BetterBatteryStats, then I'd suggest just spending the $12 or $20 on an Epic 4G Touch battery. That one is a 1800mAh battery, compared to our phone's 1500mAh and fits in our phone.

The only thing that seems to stand out is No or unknown connection (something like that) screen (which is always on lowest setting) and wifi (which I'm mostly connected to indoors) the battery that sprint sent me for the replacement is from the GS2 (that 1800mah that u were talking about)

Here's a screenshot of the battery stats I just took. Its been about 20 minutes since I unplugged that phone, when I unplugged it, it was at 98%... I believe it was at 87% in that pic.

Toggle the "other" drop down menu and select "partial wakelock".
Also, check your time without signal in: settings > battery > cell standby menu on your phone. Anything greater than 3% will be a battery drain.

So I pulled out my old battery last night and put it in the phone, and allowed it to charge overnight. This morning I put my phone through its normal use. I've been on my old battery for a little over 30 minutes and have on dropped about 8% in this time. I still feel like that's a lot, but its better than 10% every 20 minutes on the "new" battery they sent. So I'm guessing this would mean it is the battery that sprint sent that's causing the problem?

Oops wrong forum

My battery is bad too but not as bad as yours even after I delete a whole bunch of apps I don't use ,turn off LTE (my area don't have it yet),
turn off Location scan in google map (betterbatterystats showing it checking my location every 2-5 minutes). Lets see how today goes.

Battery life has been amazing for me! I'm averaging about 13 hours of of juice from 4.5 hours of screen, in other words very heavy usage. I've been showing off to all the iPhone users at work, They now want a GS4.

I knew it. I freaking knew it was going to happen. Some arse buys a quad core "super" smartphone and then starts a thread crying about battery life. really? REALLY?!
well that's okay, i suppose. you can always post on XDA and beg for a dev to cook a kernel just for you that will miraculously give amazing battery life to your quad core super phone.
okay.... rant over. now time for a more tactful response.
IT'S A QUAD CORE SNAPDRAGON. i wouldn't get too bent out of shape on battery life. And I most certainly would not compare it to another device short of the HTC One.

Battery life is great for me. I only disabled some apps, kept most of the Samsung apps, but also disable all those Air/Smart gestures. I can go 2 days without charging with moderate use.

My battery has been alright, but I don't know why "google services" is showing such a high battery usage. I had the screen off for the last hour and google services is showing a 43 percent battery usage. That seems unusually high, no?
I did some investigating with "gsam battery monitor" and it showed that "networklocationlocator" has been causing wakelocks.
