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.

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.

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.

Hi.
I've got a strange problem on my gio. The battery is draining quite fast and when there is only one percent left it switches off. If I plug in the charger now I see, that there is more than half of the battery left. What can I do to use this battery time as well?
I already wiped battery stats and made a battery calibration but there was no change after that.

Same problem here.
I've tried some ROMs and since then, the battery is a disaster.
Charges really quick and drains even faster. I am talking about 15 min with wifi or 3g before it dies.
Help please!!

In my opinion it could be a dead battery.
If you couldn't solve your problems with the other links, buy a new battery.
In my case that helped.

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.
I don't have many applications installed. I installed the battery app just now, so now what do I do with it? How do I use this information?

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.

The cell standby percentage is, in fact, greater than 3%
hence battery drain.

Put your phone in airplane mode for 3-5mins, then take it off. Check and see if battery still drains.

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?

Hello;
I've been an owner for galaxy ace 2 for 4 months now. My battery would last me 5 days until reaching 40%, then I would recharge fully without letting it go under 40% any time. My problem now is since 2 weeks my battery is only lasting me for 2 days (reaching 40%), the phone is still on stock and no applications were downloaded. I am just using it for frequent phone calls and maybe 5 minutes wifi for the whole day using "what's up". So what do you think going on?, I tried shutting off the phone and removing the battery, but that didn't help.
Thanks in advance for your help.
Regards.
5days is a dream me for example have to recharge battery every evening and many others too i think it's not that big problem just recharge evey ssncond day over night and no problems

Why does everyone still complain about battery life?
Every battery is different and how much it lasts depends on how you use the phone. Nowadays you shouldn't expect more than 24 full hours of usage from 1500mAh batteries, even on lower power-hungry devices like ours (not really, dual core).
It all depends on how you use the phone and how you recharge it: remember that Li-Ion batteries lower their capacity if discharged really deep and prefer being recharged frequently.
Very often, battery drain are caused by wakelock or triggers.
I'm using wakelock detector and cpu spy to diagnose.
With Cpu Spy you can see if your phone is realy going to deep sleep.
With Wakelock detector (or better battery stats) you can see what app is causing wakelock (preventing going to deep sleep) or triggers (events that wake up the phone to often).
Big consumers are some widgets, facebook app, Google Hangout, Google Now... some parameters in google maps...
Even if you don't install something new, you can received an update on something old, update that change the behavior of an app...
EDIT: 5 days ! a dream for me. Two days and I'm happy
Dude if i use my ace 2 for just browsing the internet 4 hours and my battery would reach 30% and i find that very reasonable.
And i read somewhere that not letting the battery discharge to at least 20% will make the battery forget its full capacity. And yes Batteries have a memory too.

NiMH and NiCd batteries suffer from the so called memory effect. Li-Ion and LiPo cells lose capacity if you deep-discharge them.

My ace 2 lasts a day of full use (wifi on, max brightness, occasional games, using facebook) and I just charge it when i get home. I never charge through the night, that would destroy the battery life completely.
Why should charging throw night destroy battery life ?
