6 hours screen on?

Sure sure it's with light use, but just the fact that it can hit 6+ hours screen time after more than a day and a half... sits pretty well with me.
No games, 30% screen brightness, 74 mins of calls, quite a bit of texting & whatsapp, 30 odd mins browsing, wifi 100%, sync on, only 1 widget.
aokp, lean kernel, undervolted, K6, extended battery.
Loving this phone!!!

Not bad at all! Especially considering 74min of phone calls.

NICE!!! Can't wait till my extended battery comes in.

Nice. I've had my extended battery for 2 days now and I am seriously impresses ed with it. It on my drive home I'm at 65% instead of 30%. I really think the extended battery should of come stock.

I got a similar 6 hour in airplane mode. I was watching a movie while roaming on vacation.
Verizon stock rom. stock battery.

Even stock SGN makes wonders with battery on Wi-Fi But still your stats are truly amazing

OP did charge the phone for a bit....like 3 times don't know for how long....but nonetheless amazing stats...

No, he didn't? Look closer on first screenshot. There is no sign of charging on those lines below the graph. Those places where graph line goes up are pretty normal and that doesn't mean device war charging.

There's no charging there.
Line is going up for a little, but that's normal and it often happens in my phone too.

Nah I didn't charge it at all, as the other guys pointed out. I remember my battery dropping to 4%, I then put down my phone and when I came back later on, it was reading 5%. I thought I was going crazy, but looking at the graph now I see it really did happen. It raised from 4% to 5% and stayed there for a bit before dropping to 4% again.
Anyway, I hope this wasn't a one off... it's not doing as well today with the same usage. We'll see...

Actually, the phone calls don't do much damage... You should be able to talk 11hours on this phone apparently...

I am very jealous. I am lucky to get 3-3.5 of web surfing.

With standard battery, you can get almost 11 hours screen on time (by doing nothing):
http://forum.xda-developers.com/showthread.php?t=1366878&highlight=max+battery
So, that's the limit
My experience with extended battery, 2000 mAH, GSM, I could get 4 and a half screen on time with 61 hours stand by time. For sure, it can go down to 6 hours or more screen on time if I down the standby time. All with stock ROM, stok kernel, un-locked
It is not difficult to achieve that knowing the limit, all depends on how you set it up and how do you use your phone.

New galaxy nexus user

I got new GN and it is very good but one thing is ruin it and it is battery life example an hour ago I took phone from charger and it was 95 and kept it in my pocket for half an hour and just loses 3 % and then played scramble with friend 4 games and now battery is 77%.
Even my old galaxy s would use less than that
Sent from my Galaxy Nexus

i dont know if this will work, but test this and then let me know if it makes a difference (you'll need to spend a whole day testing this) not just an hour
go to settings -> developer options -> in the apps section at the bottom put a checkmark on "don't keep activities"
then do a comparison
one day with it with normal phone use, and one day without it with normal phone use

I will try it tomorrow
Can you take a look at this and compare it with yours cuz screen is consuming so much
Screen is on manual and lowest brightness and wireless is off and GPS off

Pictures aren't showing up for me but the battery life is horrid on this thing. The screen is gigantic and beautiful its the trade off we all took
Edit they loaded. Looks like my usage more or less.
Sent from my Galaxy Nexus using XDA

why don't you go a few days and post your usage with normal full-day stats? You can't look at a couple of hours of usage and say it sucks. Also, why are you on EDGE? You're gonna burn more screen sitting waiting for things to load on EDGE than just using HSPA+.
But battery life is a well known "issue". The screen eats battery. Turn off live wallpapers and turn down brightness. Do all of your general battery saving things (turn off WiFi, BT, etc. when not in use) and you'll see battery life improve.
The most you can expect with "normal" (which is suggestive) usage is probably 18 hours total with 3.5hrs screen on. More than likely something like 13-15 hours.

Roms aren't going to affect battery life as much as kernel will. As far as kernels I love Franco kernel. I used to use faux with a good experience.

The battery? Yeah... They're sold from plenty of Korean eBay sellers. Official branded Samsung batteries.
And since you're on GSM, its 2000mAh (instead of stock 1750mAh). The Verizon one is 2100mAh (instead of stock 1850mAh). They are NOT compatible.

I've been using mine for a month or so.. Theoretically you should get about 20% more battery.
Tbh I don't notice much difference. But always nice to have a spare battery.

I have been using the original extended battery kit and i get easily an extra of 1 hour of screen time. It's just perfect.

Only one hour ?????
Sent from my GT-I9100 using XDA Premium App

not much different for me.. 10%-20% xtra.. heavy user here..

I've been using my 2000MAh batter for the last week and it's awesome.
On light days where I don't do much on my phone, I get about just over 2 days of battery.
On heavy days, I usually get enough to carry me to the evening with about 20% left, which is better than the previous 5% with the stock.
People must get crazy battery with 3500MAh batteries, but it probably ruins the aesthetics of the phone.

i am using official 2000mah battery kit and using wanamlite 10.7 rom with siyah kernel 3.0.1. all day i use 3g and bt for headset and battery drains about 35-40 hours...

unpossible more than 24hours.

Ok guys..so today morning i have recieved my 2000mh official battery by samsung.. I charged it for 2 hours i pluged in at 1 pm and it was fully charged within 2 hours as it was already 58% charged when i unpacked it...so finally 3 pm to 12 Am till now i am still left with 10% battery which is another 1 hour..all i can say is overall good performance as compare to 1650mh battery..so mate dont think twice go for it as the backcover is also very fit to the device ..you won't feel much bulk at the back as it has been slightly increased by samsung and it goes with the design. ..for pictures upload and further details please feel free to reply to this message...

I use the stock 2000mah battery. I can get about 4hrs on average of screen on time with CM9 or stock ICS(mostly using wifi, but 3g is on when I go out). If i don't use it much, easy 1.5 days with about 1.5 hrs screen on time. This battery provide enough power for me to get through one day. I have a habit of charging before I go sleep. So after I use this 2000mah, I no longer worry about battery in the evening.

Cool! thanks for the photos....u guys are really tempting me to get the battery too...its worth my consideration

Thanks for the pictures !

Thank you guys for good explanation and nice pictures. Now i know what i'm going to buy

I think it's almost mandatory to have the original 2000mAh battery of this phone.
With it on and a good value for the rom got a good life.

Post your battery times

I bought an extended 4800 mAh battery and cover on Ebay and I love it I currently have over 15hrs on the battery and it still has 31% left awesome, considering I am running overclocked at 1809 Mhz.
34% screen
29% cell standby
8% maps
8% internet
8% GPS tuner
5% Android OS
4% Android System
3% Device idle
2% Media server
I keep it in a steel locker at work I think that is the reason for the high cell standby #
My problem is I destroy everything delicate or expensive, and this phone is both. I have been looking for a silicone case but havent had any luck anyone see one?
This phone is going to go shotting out of my hand like a wet watermelon seed any minute now I know it :cyclops:

i get 15hrs on the stock battery?

Cell standby attributing to high battery usage is due to a glitch. It reports incorrect usage because of a miscalculation. You can find the fix for that here

What's your screen on time? 15hrs isn't outstanding, especially for a battery twice the OEM size.
Sent from my SGH-I747M using xda premium

Just search ebay for a silicon case. There are literally hundreds. I personally would go with tpu as it is more durable and less flimsy. Also less likely to be a lint magnet.

I am definitely getting better battery life with the stock battery, with 3-4 hours of screen time. I'm not using power saver feature either. Stock, non-rooted. Wifi on at home, VZ LTE elsewhere.

Heh, i was just interested what other were getting.
My GF has yet to have to charge her SGS3 except for when she puts it on the charger for the night, and has yet to run out of battery.
I've been quite impressed with the battery performance so far.
SGS3 is rooted stock ROM.

Thanks for the link missed that somehow.
Flashed the file and my screen went to 56% and the cell standby droped to 5% ? Is the miscalculation just in how it calculates the percentages? Will have to do some more reading on the subject.
Screen time was 7 hrs 54min
Only 3hrs commando........lite weight.
Lol just yanking your chain

I took these screen caps recently, but this isn't out of the normal for me. Running a version of kyanROM that I modified with kt kernel.

Remove it and replace it with the original before you take it to the Verizon store. It all depends on the store and or the clerk, better safe than sorry:fingers-crossed:

[Q] Battery life for Note 2

This is a question for the new owners of the galaxy note 2. Have you noted the "screen-on" time for battery to go from fully charged to drop dead? One of the biggest problem with the Super AMOLED devices is the (relatively) abysmal battery life when web browsing as they do quite well when playing video. Let's say if you were to primarily browse the web on the device how much screen-on time would you get?

im on my 3rd day now without a charge with heavy use.

Sorry! I don't believe Note 2 can do like that. How about your heavy meaning?

On my original Note1, I got 4 hours max of screen-on time while browsing/facebooking.
Hopefully the note2 will be an improvement over that!

I got my Note 2 today, brand new and box-fresh. At 09:30 this morning I fired it up and it had 55% battery, so I logged into my Google account, did what you do with a new Android smartphone, downloaded a bunch of Apps, really put it under some heavy load, made a few calls, SMS, plenty of multi-tasking etc. At 15:30 it was showing 6% battery life including 2h50m of screen time.
For a fresh battery and heavy use, I think that's pretty good going.

My stats at this moment:

Sent from my GT-N7100 using xda app-developers app

So about 6 hours of screen on time per full charge. Not bad, actually, its about a 50% improvement over the 4 hours of the note1.
I might still consider investing in an extra battery for those long days...

Moved To Q&A​
Please post questions in the Q&A section.​

thats odd as phone arena tried a battery test and found they would get around 9 hours continous video playback at full brightness and they say with half brightness they would come close to razor maxx at 14 hours screen time?
but still ill wait till others have tested it properly
http://www.phonearena.com/reviews/Samsung-Galaxy-Note-II-vs-Galaxy-Note_id3136/page/4

Video playback doesn't consume much battery on AMOLEDs, web browsing is more battery-consuming due to white backgrounds. Also, phone Arena said clearly that the phone was on airplane mode.
Sent from my GT-N7100 using xda app-developers app

very good battery life... for almost 2 days (I used S3, S2 before and this is a very good phone)

The mains adaptor that comes as standard with the Note II has a 5 Volt 2 Amp output that should be good at charging the battery as many existing power supplies are 1 Amp or less.
If you plan on using a car adaptor, don't buy a cheap low current one - most are only 500mAh or 750mAh.

looks like battery looking good so far from you guys..i say give it a week of cycles. still needs braking in...does the back get really warm when charging? is charge time fast?

After few more cycles the battery life is just CRAZY
And I wasn't even using battery-saver mode !

Second day
The night before charged from 3% to 100% with my Note II power on for around 9 hours. Then unplugged and heavy using from 100% to 10%, it stayed more than 14 hours. I am saying this is pretty good juice. Screenshot attached.

How long are you guys putting this on the charger? Normally put my phone on charge when I go to bed and when I wake up it is fully charged. This phone was on the charger for 7.5 hours and went from 7%-63%. WTH????

Yesterday I charged it from 10% to 100% in about 2h30
