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?

Verizon user?

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.

Yes I am on Verizon
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.

Fantastic battery life on 4.2

Battery life is very good compared to the previous releases. I ran for forty minutes with Bluetooth turned on while listening to tune in radio and using endomondo app. Google now turned on. I lost fifteen percent compared to losing 35% with similar usage. Very satisfied.
What do you think?

Why would you make a thread linking to a post you made in another thread?
Bit unnecessary. To answer the question it's too early for me to thoroughly test battery life.

I would wait for at least 2 complete battery cycles to make a thread like this.

Ditto. My phone ran like a champ on a freshly flashed ROM. Then my phone realized it was born as a Verizon-Nexus mutt and had a psychological breakdown to the point of 1.75 hours of on-screen time the day after.
Twas a sad day

I'm reading my work email over the exchange service account. After upgrde to 4.2 the exchange service process eats my whole battery so I can't tell about any improvement.

When it comes to battery life (in general, though especially true with this newest release), it's crazy how many divergent opinions you get. Some people claim to get amazing battery life (exactly what quantifies for amazing?) and some people claim the battery life is crap. This is just to remind you that unless you have a good way of measuring battery life, your measurements can be plus/minus hour(s). Someone who just leaves their phone on a black screen with no wi-fi and cell may get 10 hours of screen-on time. Someone who is watching videos with cell/wi-fi might only get 2 hours of screen-on time.
In the future, I can make two recommendations:
Always report a complete cycle (from 100% to close to 0%). This is because the battery does not discharge at a constant rate.
Always report screen on time
Average for GNexus in previous builds was 2-4 hours. I've no idea about the plus/minus, but they tend not to be under 2 and over 4 with moderate usage. I think an average of 3-3.5 hours is what most people are happy to report.

And that is really sad because my old atrix used to get over 8 hours on Wi-Fi with over twelve hours of standby time. I wish they would make this phone but with a smaller screen size. The technology used on this phone is not battery efficient at all.

This tells us nothing....u don't show ur screen on time and uve been charging off and on..

Battery life in sleep mode is worse for me. I am losing 3% an hour with the screen off, I used to lose only 3% total overnight with the screen off not per hour. I tested this over the last 4 hours only waking the tablet up long enough to check the battery level and it has gone down by 3% each time. Nothing has changed with any apps or setting since I upgraded from 4.1.2 to 4.2. I got concerned when I noticed this morning that my battery was over 15% less then when I went to sleep. Anyone else notice this?

This is very good battery by my standards.

The screen on time is good but not much of an improvement. Also it appears you had WiFi off for most of the time.

Is my battery life normal?

Hi All I just got the Galaxy Note 2 like a month ago and I've been loving it the only thing that I've been question mean if the battery life right now I'm getting like 4 hours of screen time and that's basically what I use to get with my Galaxy Nexus.
I just wonder if this is normal because I hear people a lot saying that they get several days of battery in for me I just feel like I have to charge it every day I also been monitoring the apps that I have and the background usage of them and nothing seems to be draining it.
I'm using android HD 6.0 with Perseus kernel
posting a screenshot right now..

On really heavy use, that is pretty normal. But for normal use or moderate ones, certainly not. Based on your screenshots, you have a lot of wakelocks, these are the number 1 culprits for unexpected battery drain, go get better battery stats and use the phone exactly as how you used it when you took those screenshots, then after a day or two, checkout better battery stats and find which app was actually causing those wakelocks.

Is battery suppssed to be this bad?

This is my first tablet and I expected battery to be better than this. Day 3 with the tablet, stock unrooted.

Yes is it supposed to be better then that. Although, it is possible the battery power software has a bug in it. But it should not be dropping like that when idling.

Theres definitely something up with your unit. Have you let it cycle from a full charge to 0 a couple times?

This shows nothing without actual screen on time.
I dont think the op's battery is that far off. An hour of screen on time plus an hour of streaming music. Streaming uses a lot of battery.
If you kept at that rate it would be able 3 hours screen time and 3 hours music streaming.

Yeah, media server is a battery killer I've noticed.

67% with one hour screen time is a bad. Should be around 80% at the least with screen on time of one hour.
My battery isn't great either. But not as bad as op

Posted a thread about mine but I thought I may as well post here too...
My battery sometimes drops more than one percent at a time.. Is that unheard of... Is that just the battery "settling in"?

I don't have any issues with my battery.

I will try to charge today 2A charger maybe will be better..

If anyone rally thinks the battery is an issue try stock and try removing the apps that run all the time. This would at least tell you if it is your battery out just processes. It is tough these days to not have a bunch of crap running all the time. Many of the app devs add these things trying to find info, etc
Also.. Sometimes will run the battery down faster than others. Streaming media is a killer, video, gaming, etc.. Don't expect mega screen time doing that.
Also.. Check your brightness.

[Q] battery life isn't consistent ?

Hey guys so the title says it all really. When I first got this tablet ( a month ago ) I was getting 8,5 hours of screen on time and now I'm getting less?
I'm on 4.4 running art. With auto brightness and sync on and I'm at 32% with nearly 4 hours of screen on time
Has this happened to anyone else? Thinking about flashing a custom ROM and kernel

Battery life and sound both for me. They were a bit better on 4.3.

Try Franco kernel. Even the stock settings should give you far better results than you get with stock.

I just got mine a couple weeks ago and battery life has been real disappointing. I got down to 53% with only 2.5 hrs screen time earlier today. Mostly just browsing and maybe 10 minutes of light gaming. No wakelocks or anything. I've got it setup the exact same way as my N5 and my Moto X and I get stellar battery life out of both of them. I can more screen time on my Moto X than I do my N7 and that's downright sad.
