special in that it's less useful because you did not post screen time?
you probably didn't get much past 4 hours screen time if you even got that far so it's not like it's an achievement.

I see very little screen on time. I have done 18 hours stock with 3.5-4 hours screen on but it's on it's last leg at that point. Lol

Why is there so much awake time even though your screen is not on? And unless you got really high screen time, 24 hours isn't that all impressive.

I got 3 hours of streaming music over 3G with 30 minutes of screen time today until i hit 15%.........
Forgot to add, my tbolt with extended battery would take me from NY to Philly using navigation the entire way and streaming music and at the end of 3 hours drive with the screen on I was down to 75%......

It's extremely easy with Juice Defender: Ultimate and the Extended Battery..

GSM, Apex ROM, ORIGINAL 1750mah battery.
1 day 4hours
3hrs 13minutes screen ON time.
I forgot to screen cap the other pic of the huge graph.
This is only on WIFI though during the weekend when I was home all weekend long.
I can't get this high if I was using cell data/wifi during workdays.

Wow. I think I won. I took out the battery and waited 2 days and then I put it back in the phone. I got 2 days and 16 hours out of that.
Try to top that.

Some of us have corporate email, does juice put the device to sleep? I need push email.

I can get 3 days quite easily if im busy and dont get much use out of it.
This state was with about 3 hours screen time.
The main point to take about battery life is that you can make it use all during screen off with Franco kernal and AOKP for example but if your gonna be playing games/watching films the battery will hollow out in no time (notice the 2 big dips on the pic that was while playing GTA3 on full brightness)
So the best you can do is minimise the battery drain when you are not using it. Otherwise its all about screen-on time and a bit to do with how much junk you have running
Setup as detailed in my sig

Another "I get amazing battery life but barely use it" type of thread. Seriously we all know how long the battery can last based on the usage.

Yeah and I bet you had the screen on for about an hour.

I'm on lean kernel and quite frankly, I couldn't tell you the last time I didn't get at least a day. You want better battery life? That is the kernel you want to be using.

How much battery could i get?

Whit the following settings: screen turned all the way up 4g turned on few times just to check fb/xda and most of the time listening to music whit screen off about 50 texts a day ? Could the following leave me whit 50% battery at least ?

Guess you'll find out. There's no formula that you can just see what your battery would be with specific criteria.
There are soooo many more things that factor into your battery, down to where you live and the load on towers you're connected to.

Also make sure your Freeze the Maps app or remove it, it tends to open randomly in the background and drain battery. I get an extra hour or so since I did this.
I normally get 16.5 hours with 3G + Bluetooth on. I don't have anything syncing though (all manual updates, Tasker forces a sync every hour to check e-mails.
Screen on time is ~3 hours or so.
Music (Rdio/Ubuntu Music) kills battery more than anything else for me though. Even with sreen off I get at best 2.5 hours of music

Didn't see this before. I had an Amaze 4G and if one thing sucked, it was battery life. I make it longer on a standard batter in my GNex. I put an extended one in the Amaze just to get it to were the GNex is normally (albeit sense is probably to blame here).

Well people there reports 14 hours of battery whit 4 hours screen on time here barely 3 hours screen on time and 6 hours total im not a heavy user tho gonna get the xperia s coming for rogers next week! Thanks everyone for helping out though

T-Mo Note II Battery Life Thread: Post Screenies!

Figured I start a thread specifically for the T-Mobile variant. I will say that I'm pretty pleased with the battery life thus far. I hated having to give up the ease of some functionality just so my Samsung OG Epic 4G could make it through the day. Meaning, turning off bluetooth, live wallpaper, wifi, etc.
I feel like I haven't had to do that even though there is a battery saver mode already. I'm currently sitting at 54% and it's been a day since taking it off the charger.
I currently have all the bells and whistles going. Live wallpaper and facial recognition to unlock. S-Pen detection and the whole 9. Anyhow, just wanted to see what everyone else is getting.

I'd be happy with 6 hours screen on time

i had the galaxy s3 before the note 2 and i have noticed huge battery improvements

I was briefly reading through the manual and saw this:
Do not wait until your battery is completely depleted before
charging your device. Repeating this process of a complete
discharge and recharge can over time reduce the storage
capacity of any battery.
Pg 15
just thought I'd pass it along. I usually run my battery all the way down and let it die before recharging:

My guess wouod be your cell signal. Lot of yellow in there. Weaker signal means more battery drain

Good point. At work I'm on wifi but when it's not it is on edge

Unbelievable. Its DOUBLE what I get on my note 1. This is the first time i can remember in years not changing a battery during a day.
I have had WiFi on most of the time.
I never thought I would see 14 hours.
Sent from my SGH-T889 using xda app-developers app

The battery life on this is simply amazing. I am still shocked to see how good it is. I tried everything today to run it down. Barely even used WIFI today. Basically all 4G. Screen brightness was about 50% at least all day. Never below as well. Crazy awesome battery

My battery life is insane. Ive used my phone nonstop all day and its still going. I should easily get between 8-9 hours of onscreen time.

How to conserve battey life?

My battery is dying faster than ever. I am on stock rooted JellyBean. My battery dies within four hours and right now i am streaming pandora and the phone is hot.
Could it be that I have a ton of apps on my phone? This did not happen before. I have about 350 apps:what: installed. Lol please do not judge me lol

Jesus Christ 350? That's a lot of apps running in the "background"
Is that all you do is listen to pandora? Because I'm just purely stock JB (not rooted) and my phone last 2 days without being charged and I stream pandora as well.
I honestly get better life when my phone isn't rooted. Very weird I know but I think I do anyway
But I do know a lot of battery saving tips..

It could be all of those apps then. Lol i forgot they run in that background. Oh wow lol that explains it. Im gonna uninstall most of them then lol

Do you also have your 3G always on? I always turn mine off when I don't use it. Also conserves battery
But yes 350 is a crap ton.

As with most phones, apps in background will kill battery, Screen on/brightness.. Times of no signal. Things of that nature.. When rooted i usually set background processes to 1 or 2 running at most.. Sign outta Gtalk (It's an auto sign in), Notifications (FB, and such) off (unless you really want on) Sync durations to longer intervals (Emails and such) i usually set mine to 4 hours or more, weather sync as well.. Those things will help improve life some what as well. No i don't have the S3 yet, Currently on an S2 (S3 comes Sat) but these are common things across the realm that will help.

Everything he said is true. Limit your processes which also helps a lot but not with 350 apps.

If streaming Pandora gotta have that connection... I typically run Juice Defender to auto disables 3g with screen off, enables when screen on.
My phone is tethered to a motorcycle battery, so my battery life is great.. Iittle hard to carry around a times.. but gets the job done.

Try using WiFI when you can more often, it actually consumes less battery than 3G, also download advanced task killer and only allow important apps to stay active when not using the phone, my battery life is easily 8-hrs even playing Internet Radio most of the day.

What you need is better battery stats. That will help you find what's draining your battery. Also we don't know what apps you have or what's even draining your phone. Those screenshots don't really give us much to go on

just judging by your 2 screenshots its looking like your phone is constantly looking for a signal. That usually KILLS your battery.

I just posted 2 new ones, I always have service to my knowledge except for one turn in my town and its like 3 minutes, but my screenshots of betterybatterystats says different...

Go to settings/battery and touch the graph at the top. Take a screen shot of the screen that pops up and post it. Here is mine. Curious as to what yours looks like. Also GSAM battery has monitor that will tell you what % your phone's signal has been (second shot).

In better battery stats at the top drop down menu take a screen shot of kernel wake locks and partial wake locks. This will tell us what is draining you down.
