Epic battery life! :D

Ive been trying to get my battery life to 24 hours! i am so close
anyone getting over 24 hours of battery life? share how ya did it!
what kernels are you using? Different Roms? are you over clocked or under-volting?
lets see some screen shots!

There are so many battery threads already out there..

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.

Post your battery life

I don't see a thread like this for the T-mobile variant so I figured we can have our own. It would be nice if you included the following with your posts:
screenshots including on screen time, information about your rom, kernel, etc. and estimated talk, text, browsing, and gaming time, and what brightness you had your screen on (auto, full, etc.). If you use something like SetCpu with profiles list your profiles and settings here too.
I'll start:
This is only my second cycle charge on this device. I only got it 2 days ago now which means it still has room for improvement
My sig has my rom info and I basically did a lot of twitter browsing, about 100 texts a few short minute phone calls including an hour long call when it was at around 10%, a lot of XDA reading, and no gaming today.
I have the device overclocked to 1.89ghz with this kernel with min set at 384mhz ondemand governor. I have a profile that clocks down to 1.5ghz at 50% battery life and another that clocks down to 1ghz at less than 10%.
I've never had a device give me 4h on screen time especially with the abuse I give this device. I can't wait to try out other kernels and roms to see these numbers rise.

I could get a day and a half with no tweaking and low usage, on an average day I'm getting ~15 hours before it starts whining about the battery

Yeah but what's your on screen time?

Right?! That's what it comes down to. It doesn't matter if your battery life is amazing if the reason why is because you barely if ever use your phone...

I'll post tonight just got my new anker battery.

Considering your screen was barely on during those 18 hours I can see you didn't use the device much. This is barely average.

Throwing bricks since 2008.....and proud of it.

I could make it 24 hours easily with light usage. With moderate to heavy usage, probably around 20 hours. It really depends on how long the screen is on though. This phone has amazing battery life. My HTC Amaze probably only lasted half as long.

I agree, best battery life I have had out of all of my previous smartphones. I am still testing roms and kernel combinations to figure out what works best for how I use my device. I'm in the middle of testing FSG3 rom with trinity kernel. Will post up battery usage within the next 2 days to compare to my previous Stock rom with Adama 003 kernel battery life.

My Screen
Pretty Good so far, Stock Rom - Rooted - Still 40% left.

This is with the fsg3 rom and trinity kernel. First and only cycle so far. Brightness 100% wifi on most of the time, and data and gps always on. Played music for about half an hour and browsed xda for half an hour.
Edit: screen on time was just over 4 hours deleted the ss by accident.
Will post up the 2nd cycle when it's done.

New screen shots after a few cycles. Again fsg3 rom with trinity alpha 36 kernel. Brightness 100% wifi on most of the time, and and auto sync also on.
Look at screen time on not just total battery time. This is what determines good battery life not letting your device sleep on your desk for 2 days and saying you get amazing battery life.

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:

dam thanks i was about to do a few full discharge and full charge again, thanks for the info.

I'm not getting great battery life yet and have had the phone for over 24 hours since I picked it up yesterday morning. Can't pinpoint wjat could be draining it.
What do you guys think?

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.

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.

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?

Bit unnecessary. To answer the question it's too early for me to thoroughly test battery life.

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.

Is battery suppssed to be this bad?

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.

67% with one hour screen time is a bad. Should be around 80% at the least with screen on time of one hour.

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.
