Screen Time On Numbers

I'm starting to see that looking at battery life, we shouldn't be looking at any number but screen time on.
For me, no matter how long I use my phone. Let that be intense browsing to listening to music, my battery will not die until it reaches near the 2 hour screen on time.
I am trying to figure out if that is low compared to other users. If people can share that would be great.
thanks.

Hour and fourty five to two hours fifteen seem to be about the norm. Some users are getting ~3 hours of screen time with a lot of patience, kernel testing, fine tuning & tweaking as well as careful useage. I think we'll all get there sooner or later. In my opinion kernels can/will get MUCH better for this device. Only time can tell, but I'm not trying to put a show on. If I need my phone, I'm going to use it...whole point in having it.

Most GSM users get around 3 hours screen on time I believe.. I get three on a bad day

I have GSM with 2000mah extended and get average of five hours screen time and have Gmail accounts syncing Facebook weather and it lasts all day so I'm finally content with my phones battery life. Just don't need more

Actually both
1.standby
2.and actual phone usage
Standby can be sorted out via removing stupid apps or configs causing large amounts of wakelocks.
Actual screen on time AFAIK can only be done via lowering brightness, or maybe try reducing screen voltage(however, current may increase rendering this mute).
Having a lower dpi screen means less screen touch/input for scrolling so that also helps, it also looks great due to the high res screen (large ppi count).
obviously if you are doing battery intensive stuff like playing games or gps. Not much you can do there.

This is what I'm getting on average , GPS and bt is off everything else on. GSM 4.0.2

That's about my usage, I got two and a half hours yesterday. But I've since changed to Nitroz's Black Exodus so I hope to get more toward the 3-3.5 hour time.

I get between 2 and 2.5 hours with heavy usage on stock battery, GSM version, data on (2G screen off), sync on, AOKP M3 + franco kernel w/ turtle governor, 350/1000 UV. I'm trying gazelle with 700/1350 and I ordered the extended battery off eBay.
If you don't get at least 2 hours screen on with heavy usage (games, internet, etc.), research what is draining the battery.

On an average day I get over 4 hours screen time. A good day sees me hit 5 hours and a long time without charge can reduce this to around 3.5 hours.
I use the official extended GSM battery. Currently running AOKP 21 with Franco Kernel 14.4 undervolted by around -50mV. Auto-Brightness.
Here is an example of my last cycle.
Regards.

Stock everything GSM... Intermittent use of Skype. Wifi always on. Screen at 50%. Google calendar and mail sync.
4.0.1 just under 2 hours.
4.0.2 just over 2 hours and 2.5 hours max.
Average 16 hours without charge
I think it is just as important to post screen brightness as well as time on.
I've not yet tested a lower screen setting and I would be sacrificing its sexiness.

At least 4 hours screen time with:
Version: GSM GNex
ROM: AOKP Milestone 3 (power saver mode off)
Kernel: Lean Kernel
Battery: 2000 mAh
Frequency: 350/1350 InteractiveX
UV: -70 across all
3G/HSPA/LTE: 3G/HSPA and my network doesn't support 2G
What's off: BT, WiFi unless I'm home, Sync for Calender Contacts Browser and Photos.
Daily, I use: Netflix/Poweramp/Spotify/Reddit on my daily commute. Phone/Poweramp/Spotify/Reddit/Browser+ in between commute.
The WiFi is when I got home, and I didn't charge overnight, which explains the long straight line. My brightness is almost always at 40%, sometimes I go 100% if I get home and know I can waste the charge, sometimes it's at 0-10% if in very low light.

I charged it up during the day yesterday, but then hammered it syncing my emails, sms messages and other things.
So, last night was my first real charge. I took it off the charger at 6am this morning, and right now, at just a few minutes less than 5 hours, I'm at 83% with 70% use being cell standby.
I'm sticking with HSPA+ today, because I know that will drain the battery more than WiFi (at least that was the case on my Atrix) and I'm trying to get a feel for the battery life when away from WiFi.
Now, full disclosure, my phone has 6 email accounts setup for push. An Exchange account, two Gmail accounts and three Imap idle accounts using k9 mail. Still, I would say it's burning battery at a little higher rate than my Atrix with those same six push email accounts.

5 hours and down to 40%.
:-(

I'm seeing a significant increase in battery life whith the s3 over the s2

I'm a bit of a light user, but a little heavier than average given new phone.

7.5 hrs @ 57%.
I'll post screens when I can.

5 Hours, 45%, screen on 2 hr, 12 min.
Interesting thing: I have a Pandora Widget on my screen, have not used it at all, and 13% of my power, and show son for 22 min.

9.5 hrs @ 29%.
I am using the default juicedefender profile.

Cell standby hogs the battery more than other phones like US One X with same SoC. I think kernel devs can work on this since this is not normal.

To get a good idea on battery life, everyone needs to show their screen on time as it should be the biggest drain.

^^ I had power saving off for the first 3 hours of the day, and screen was set to 1/4 brightness. I changed screen to auto brightness, disabled wifi network scanning/notification, turned on power saving mode (all options), and it's been like that since about 3 hours into the day. I've done some driving with Slacker Radio streaming via bluetooth to my Jeep.
Seems like cellular standby eats juice. I am in an LTE area.

is the a way to turn off LTE?

This is mine so far, don't really run any battery saving appsetc. Cell standby is a bit too much.

Battery Life for you Heavy Users

I know another battery life thread, but I want to know what battery life people get that are heavy users. What i mean by heavy is people that play games for an hour, watch videos, surf the web, music, download, calls, text. Things that would drain the battery quick and because the screen is on.
On a regular day I mostly text get about 1.5 hours of music and 2 hours of video/game. I don't play games all that much just watch videos during my breaks, surf the web allot and download small files. I have always kept WiFi and GPS enabled on all my android devices.
I had the SGS for 2 days and noticed it only lasts about 12 hours, my previous phone (hTC Raider) with the same usage would last about 14 - 16 hours.
What do you guys get? somewhat disappointed with the battery.

4 to 6 hrs screen time.

@ I_FLY_Z3R0
That's impressive I may have to check out that ROM. It funny how you guys get around 16 hours and i only get 12 I wonder what it is?
I'm starting to remove bloat and hopefully that will improve my battery, will post back at the end of the day.

Out of curiousity is everyone on a custom rom, is anyone on a stock rom and getting these numbers (I apologize if i missed this but i dont think i saw it). Im rooted but still stock on sprint and I am getting about 8 hours. I have about 4 gmail accounts sync, 4 groupme accounts sync, gps and wifi enabled. I typically lower my brightness unless im outside or in a hard to read area....any ideas? I was really ok with not trying custom roms but if i can double my battery life by doing so i might reconsider....I was on the OG Evo before and flashed like crazy to get better battery life but no matter what others said they got, I only got 5-6 hours on similar setup that i just mentioned.

I'm testing my phone to make sure it lasts me my heavy day. Coming from GNEX i have to make sure that it's worth $600 i just paid.
now i'm getting 5 hours of talk time + 3 hours screen time (auto) + 20-50 text/emails. this is with power saver setting without CPU max limit.
and at the end of day (8PM) i have around 18 hours on batt, and 20% left.
Hope that helps.

This was extreme usage. Audio constantly playing and tethering on most of the time.

Judging from the fact that he's on Blazer rom (I used to have a GSII), I'm assuming he's on sprint. Assuming he's on Sprint, I'm assuming he does not have LTE in his area yet. This could account for the huge difference in how long the phone lasts overall.
Being on AT&Ts LTE, I can get around 4 hours of on screen time and 15 hrs overall of medium use.

Here are mine. Mostly idle, lots of reading(Game of Thrones books, awweesome!), emails (all work related) and light gaming. 5% left after 20 hours, almost 4 1/2 hours screen time. I am running stock rom, rooted and I debloated a bit(few pre-installed apps, gmail, email, etc as I use other apps for those needs).
Uptime 5% left on battery.

[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.

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

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

Battery Life Problems

How's everyone's battery life? I get down to about 5% by the end of the night with light to moderate use and standby time seems to be pretty terrible (5% drain an hour or so).
I checked in the battery info and it shows Android OS at the top with 66% use and when I click on that, it shows Keep awake at 3 hours and 49 minutes.
Anyone else having this problem? I did a full wipe and that didn't fix anything. I'm also running the latest update.

I can usually last a day with moderate to heavy use. Haven't found it to be any shorter than that so far. Try turning on the processor eco mode

I wake up at about 7:00a.m. and go to sleep at around 12:00a.m. And I usually go to bed with about 30% and this is with moderate use, with full brightness and eco mode off.

My battery life is pretty atrocious as well compared to my Evo LTE.
I'm at 40% at the moment after 7.5 hours. That's mostly wifi and without 4G. Have tried keeping the screen at 40-50% brightness, eco mode on, quad control, on, etc.
Even tried cycling it a few times by letting it run all the way down and charging until 100% with phone off and it's there's been no improvement.

I have been surprised at the battery life of this phone. I was annoyed after I bought it because I didn't realize it didn't have a removable battery and I typically buy extra batteries. I gave it a try though and yesterday I used it moderately while at work for 12 hours, used it for streaming audio on the way home, and after a total of about 14 hours without charging it was only down to 70%. Eco mode was on, and screen set to 67%. Periods were with 3g, 4g, low signal, and wifi.

Dont know why you would have such bad battery life, i used my phone all day yesterday from 530am til i went to bed last night at 1115pm only 30% discharge at that point , i dl a rom on it for my gs3 when i was going to sleep 789mb and woke up this am to 36% bat left. I am truly pleased with the performance so far.

This morning I pulled her off the charger and browsed reddit for an hour with the screen at 63% and lost more than 20%.

At the time this was done it was at about 40ish%.
At the moment I am at 25% after using my phone about 16 hours. Android OS is at 51%, screen at 19% with about 3 hours clocked in.

By this point I expect a minimum of twelve hours on the battery with at least two hours of screen on time. Im very happy with that if I use the screen for more than two hours it'll last about eight hours which is still good. This phone idles very well I expect it improve with future updates as well.
