Please help me with my Nexus

How do I get this phone to hold a charge for a day? Right now I get about 6 hours of battery life if I am lucky on decent use.
It is rooted on a black ice rom, running that Franco kernel. Is there something that I am not doing? Do I have to overclock it or?
I seriously almost traded it it for an iPhone just because of the battery issue. Like, it drives me insane and it takes away my freedom lol
Any help would be great

if you're only getting 6 hours, then you're a heavy user. Not much you can do about that, except use your phone less or charge it more.

Run stock for a while...

I'm on sprint and out of the box it was bad bad battery life. I'm sticking with it though hoping someone comes up with a way to get better life out of it.

Use an app like CPUSpy to see if your CPU is ever going into Deep Sleep mode, and an app like BetterBatteryStats to figure out why not. You can also look at Settings > Battery to see what's using up your battery. Tapping the graph at the top may give you more details.

I really am not a heavy user.
So switch it back to stock?

Usage varies man .. i have decent battery life so far with Franco 185 linaro with AOKP linaro rom. I keep the governor set to conservative . And I do overclock as much as I can ...might even be better if I didn't do that . But I get around 10- 14 hours on that setup . I text a good bit and twitter occasionally but spend most of my time on flud news reader. If you stream music all day or Netflix or something then you aren't going to get great battery life .
Make sure your screen brightness isn't high when you don't need it to be ..since the screen is generally what uses the most battery .
My best battery was with lean kernel and slim rom 4 ...but since I went to this new linaro I will forfeit a little battery for fluidity.
The key is just to experiment. There are lots of combos out there and they all work differently for us. There isn't exactly a one stop solution . Just tinker and you will find the light
Ps: I have the 2200 extended battery from Verizon . It is a necessity if you wanna get normal usage. They are listed at forty bucks or something through Verizon ...but if you go to the store they sell them for 20.

Best solution would be to get an extended battery to last you the whole day or an extra cheap one to swap with at the middle of the day

What is your screen on time?

Yes, do this before blaming the phone. Also pay attention to the apps you install and see if any of them are causing the problem. Stock roms are usually less buggy than custom roms.

You would also get more help with your Question in the actual Q&A section.

And how do I check my on screen time?
And I just noticed that my brightness was half way lol.
And that battery idea is good. I will just get an extra one and keep it in my wallet.

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 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

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!

Battery Life

I recently bought a GSM galaxy nexus (NTT DoCoMo version) and I use it on T-Mobile's prepaid network. The original battery that it came with was terrible.. Literally only lasted 7 hours regardless of screen on time. So I bought a stock Samsung battery off eBay thinking maybe it was a bad battery. No help whatsoever. I've flashed different ROMs, radios, and different kernels. Can anyone help me figure out what's going on? I had a Sprint Galaxy Nexus and I could get up to a day on the battery with 2.5 hours of screen on time so I know the Galaxy Nexus can last a long time. What's the deal?

Could you post some info on battery drain statistics from battery settings tab or preferably gsam monitor over a full drain? I could probably help you out, just need some more info. Also try flashing fancy kernel if you haven't already. This is a newer kernel that gives the best battery life you'll find freshly flashed.
Before discharging toget battery stats I would try charging to 100% and using "battery calibration" by NeMa to clean your phone's batterystats file and then drain to zero with a screen flashlight or running gallery slideshow. This can always be a problem no matter how healthy your battery is.

This is what I have showing for my battery so far. I flashed the newest radio last night and that seems to have helped a little bit with the battery. I have tried the battery calibration and it didn't really seem to help much.

I have flashed a stock 4.2.2 ROM a week or so ago and I was still having this issue. I bought a new battery too and its still happening. Flashed the fancy kernel today and it seems to be helping a lot actually.
Sent from my Galaxy Nexus using xda app-developers app

The stock kernel performs way better then what you are experiencing. A custom kernel may help a bit, but it's not magic. I'd recommend using the app BetterBatteryStats in order to find out what's going on.

Do any of you think that me restoring apps would have anything to do with the battery drain? I'm not seeing anything out of the ordinary in the GSAM battery stats but the battery drains way too quickly. 10% per hour even when I'm not using it..

Glad to hear that fancy kernel is helping. It's probably the closest thing to magic you'll find. I agree that 1 hour of screen time and under 12 hours is under par, but I was having these same issues 2 months ago and could not believe how crappy battery life was. It really got better though trying a bunch of different radios to find the right ones, using minimal gapps/resource hogging apps as possible, finding the right build.prop tweaks to use, and most helpful flashing some good reliable kernels like fancy and AK/anarkia that have incredibly useful customizations that stock just doesn't have, I.e., contrast and color settings, battery friendly governors and frequency profiles, optimized smart-reflex, and custom regulator voltages for display.

Well, didn't feel like it lasted too long. Fell asleep with my battery at 33%, woke up 3 hours later and it's dead. I'm ready to throw this phone out the window.

I've tried to find a rom and kerneI that would help with battery too, nothing made that much of a difference though. I use the 2x battery saver app now. I get at least double the battery life sometimes more.

I see you got the app. Good. Now a few minutes isn't enough time to gather reliable stats. Review the results after a full drain cycle of the battery. Check partial wakelocks and alarms for suspicious activity.

Here's what was listed on BBS after a full drain. Do you see anything unusual? I turned my data on and kept it on 2G to prevent the no or unknown signal from eating more battery but that was the only change. Battery life still looks terrible.

No need for the snake oil app, as simply unplugging the phone after a full charge wipes battery stats. Wiping battery stats and draining to zero aren't going to have any bearing whatsoever on this issue and would needlessly shorten the battery's serviceable lifespan.

Whoops.. I forgot to screenshot those. I'll get those later today. So I put my phone in airplane mode to see if maybe it was the reception... Phone kept draining. I will try to wipe everything off the phone later and not install any apps and see if that helps.

According to these stats, it looks like Google talk and the calendar are my biggest wake locks? I disabled Google talk, turned off location history for Google maps last night, what should I do about the calendar? I feel like my phone is becoming useless because I have disabled so many things.

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.

Need iPhone-like battery life

I'm sick and tired of all of my iPhone friends having their batteries going strong after heavy usage and I'm struggling to keep up.
I know, I know, it must be an app or some process, but the battery indicator in the settings shows nothing irregular and I have no idea how to interpret Better Battery Stats.
Hell, I'm even on a Mophie Battery Case to get me through the day, but it makes the phone hotter, heavier, thicker, and slippier.
I've tried so many ROMs and kernels and nothing has been able to get me from 6:00 AM to 6:00 PM with moderate usage (mainly sometimes using Internet browsing apps such as Reddit or Dolphin, and playing some on device music).
I need your input. I love this phone but the battery is really giving me buyer's remorse regarding my contract that ends December 2014.
I'm currently rooted on 4.3 SlimBean and its stock kernel.
I need suggestions, any and all!
Most importantly, I would like your absolute best combination of ROM and/or kernel in terms of battery life. Thanks in advance.

Dunno if it will help u but there's this app on Google play called setcpu for root users. Basically it let's u control your CPU power. you can over clock or under clock your phone with it. So if u wanna save battery life through the day. U can limit the amount of power or phone uses. Hope it helps. If not then u might need to buy a new battery. Good luck.
