Now this battery life is more like it

-Wifi and Bluetooth on whole time
- Tons of texting, a lot
- Over 1 hour of phone calls on Bluetooth
- Over 3 hours of A2DP streaming
- Periods of no signal (subway)
- Screen on for 2 hours
- Google Reader and Web browsing
- Used the phone as I would normally without thinking about battery at all.
Very very happy. UPDATED with recent screenshots before I plugged it in.

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.

Wow! I wish mine was as good as that, seems to be getting better with each charge though, which is a positive.

Most I have got is 12,
Hopefully this will increase over time

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.

I'm currently on 1 day 1 hour, with 50% left. Although with light usage.

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.

43% - 14h.. screen taking up 48%

from what I can see, apart from the screen, the biggest battery hog is wifi/3g
I installed Juice Defender and I am getting fantastic battery life now:

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%.

AMAZING battery life!

I am completely amazed at the battery life I'm getting on this phone! Considering what a powerful device it is I would have been quite happy with getting about 12-15 hours out of it but ever since I loaded in the ROM and recent OTA update I have consistently got 2+ days of what I'd consider to be light use.
I'm running Calkulin's 2.0.1a ROM+included kernel, EK02 modem, and I also have Tiff's Nothin but the Honey v5.0 theme.
I attached an image of the battery stats page so y'all can see I aint lyin'!
Anyone else get this kinda battery life out of their E4GT?

Yeah I am getting pretty amazing battery life after calibrating properly and running blazer from 2.0. When i leave it on standby at 100 it only drops to like 80% after 24 hours. Love this phone!

This seemed to start after one time the phone got blazing hot while charging.
It was just sitting on my bed. It was so hot the processor was throttling and
everything was jerky.
It's never happened again, but now I never see > 99% on my battery. :-\

I agree. Running Calk's 2.0.1a with Rogue 1.3 kernel, I get great battery life
10 hours on extreme use during workday with tons of calls...GPS...tons of texts...lots of emails...on screen time of 3 hours+.
On light weekend use WiFi I get 30 hours easily.

If you think about it logically, the instant you being using your battery, its NOT 100% charged anymore.

That is the true battery life being displayed... It is impossible for the battery to be 100% full after pulling the battery out it would immediately drop to 99.9% it makes sense to me and is actually something I've wondered about on all of my other phones

I am getting amazing battery life with unnamed rom . still at 50%

EK and EL releases helped a ton IMO. Even if I didn't use my phone all day on EG I might end with 40%. On EL I can go with no use and still be above 80.

That isn't a clear indicator either. I could have Pandora and GPS running over BT in my car which uses a lot of battery and that wouldn't help.

You guys should post screen shots of the screen on time. That is what will decide whether you're getting great battery life or not using your phone.

I don't have her phone in front of me but on 3g and wifi (half and half but barely used it at home) yesterday at 16 hrs it was at 65% w 1.5 hours screen on. Completely ****s on her previous phone

I have been unimpressed with the battery life. it will "NOT" last 1 day. heck sometimes I have to charge it twice
I might have a bum battery?? I just ordered the samsung charger with extra battery brand new. will see how that goes.
for now I use the 3950mah extended battery (lasts a full day) that I got off ebay.
I tried to let it update over the air but it always fails at clock widget and won't install the update?

When did your battery life start to get better?

I have had the phone for 5 days and with fairly light usage, I am still not getting good battery life. I turn off all data and wifi when not using it and screen on time is below 2 hours.

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.

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.

How's your battery life with low-med usage?

I'm getting some really good battery life with light usage so far.
1d 3h 33m
Edit

I m getting similar results, light usage I unplug at 7am and plug back in at 1am with ~50% battery left.

This screenshot doesnt say much, tap at the graph - that the screen to show off

WIFI seems to be much better. With my LTE on I can barely charge the phone LOL. I wouldn't trade 20 Mbps down for bettery life.

I'd say my experience has been the opposite of what's been reported. With low to medium usage, I'm lucky to get 8 hours. I don't think I'm doing anything wrong. I use setCPU to put my phone in battery saving mode and underclocked all the way when the screen's off. I kill apps whenever I notice a lot are running. I dunno. Coming from an iphone, I'd say my battery life has been horrible.

I've never been an iPhone fan, but since the iPhone 4 the battery has been phenomenal. Battery life is constantly improving on Android phones, but it seems like every time something new is introduced it gets significantly worse. The 720p screen and LTE radio don't seem to be helping the battery cause. In the Nitro's defense, I haven't carried it an entire day to see how it works out for me. My Inspire could charge completely in about 2 hours, this phone will have changed less than 50%. But I have 20 Mbps download!!!

This is interesting since I don't kill apps, I don't use setcpu, and have only done minimal debloating. I do have pretty decent signal at my workplace (which is 4G, not LTE) which does make a big difference.

I wonder if it's the point? Maybe codeaurora just knows better how to undervolt SoC than setcpu does, just maybe? If Malnilion only tried to stop using setcpu could it made any difference?

Well, I'll be damned. setCPU was the problem. My battery life is lasting much longer now. With medium usage I'm at about 15 hours on a charge and have 7% left. If anybody is having a problem and is using setCPU, don't take my word for it, uninstall setCPU and see for yourself.

my experience has been the same using setcpu on my nitro. not sure if there was a sw conflict or if the stock sw simply does the job better but this phone runs much better without setcpu.

If you're using a USB port to charge that could be why it's so slow.
Edit: I am too, I'd say it's around 3 hours or so per full charge. Maybe slightly longer.

Good point. Now that you mention it, it does appear to charge faster when plugged into the wall. Well that kind of sucks. This thing takes forever to charge. I'll try with a wall adapter when I am home again and let you know what I find out.
It's kind of hard to always have a wall charger with me though.

It is not blackberry crazy short timing charges but I can charge it less than 2 hours from around 20% left using stock 1.5 amp wall charger. It definitely does not charge long.

Am I correct to assume that the 2.1amp car charger would charge better/faster than the 1.5amp wall charger? I ask because with the wall charger I still consume power faster than the charger can keep up while watching SlingPlayer mobile.

Probably so, this phone is a battery draining beast. Every review I've read says LTE phones have terrible battery life. LG should have had an option to disable it and 3G. Oh well, I'll live with it while streaming on my 22 Mbps DL connection.
Sent from my LG-P930 using xda premium

That's just it though... I'm not on LTE while using SlingPlayer. I'm on 4G out in the field. My car charger doesn't say what it is, but I assume it's 1.5amp. I download "Advanced Task Killer" app, but everything I "kill" comes right back up. I think there's too much crap running and sucking down the battery. I really need to figure out how to root and freeze bloatware crap.

Same here. Battery life was a concern for me when I was first considering the phone. But I found that I can go a full day on a single charge. so I don't even worry about it anymore.

Limit the Note 2 from 1.6Ghz to 1.1Ghz with build in feature to save battery

I know most of you already notice this but if you don't:
In Setting/ Power saving mode, check the "CPU power saving" then your phone will be limit to 1.1GHz max from 1.6Ghz.
I would suggest to tick on the "Screen power saving", "background color" and "turn off haptic feedback" to save some extra juice.

LTE on. 24h unplugged. 75% screen brightness. Full heavy haptic feedback. Heavy gaming and Internet use. Phone calls. Texting. 3D live wallpaper. Still 7h screen on time before the phone finally had to be plugged in.
I don't know what you use your phone for but I'm going crazy on mine and can't kill the battery. If you need more juice, then more power to ya. I can't fathom why.

Try a day without charging your phone at your desk. Yesterday I pulled in about 7 hours of on-screen time. That's with LTE and anything else internet intensive you could imagine. The only way you'll overcome that worry you have is to test it out yourself. I'm sure you won't be disappointed.

I would understand this philosophy if the Note 2 didn't have an easily replaceable battery, but in a years time you could replace a poor battery for cheap. Just recently the stand with extra battery and charger was $30 on the Samsung site (it may still be that price)

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

I'm still suffering from battery OCD after coming from the iphone 4S. Now I feel like plugging in my note 2 whenever I'm at my desk at work.... So you guys don't think I need to?

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.
These aren't nickel batteries...they dont need to be trained or "cycled"

I'm a battery test engineer so I have played around with Li-ion batts.
If you can keep the phone at cool temperature and charge at 40% and stop at 80% then keep doing 40-80, your battery will last double long

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.
