Well this is helpful, thanks. Sounds like you are getting better battery life than me. Although I would say I definitely am a "heavier" user than you. I used to make it to about 3pm with my GS1. I'm getting about the same with my GS2 if I leave the brightness on auto. That's if I don't use YouTube for more than a few min. I too would like to know what your screen on time is at the end of the day.

That use and that battery it is simply a lie.
[Galaxy S II General] sgstwo:
The screen is definitely a battery drainer. Don't set the screen to 100% brightness and record 1080p videos. Battery level will be at 0% in less than 2 hours.

Can we get back on OP's original topic of display brightness vs battery life discussion, this is a topic I'm interested in as well as I leave mine on auto-brightness and display is always #1 on my battery consumption list.

Maybe intruda can start a thread called "How my battery life is superior to everyone else's SGS2" and the dissenters can go there and call him out. Just sayin'.
[Galaxy S II General] Locster126:
This is my usage today with auto brightness. Mostly at 30%-40% brightness with 45minute gaming and rest browsing. Music. Youtube.

Im impressed.

It's been 16h20m since I unplugged my phone from the charger.

Battery is now at 18%.

The Screen has been on for 2h10m with auto brightness on.

Phone has gmail/twitter(every4hours)/weather(every2hours) in the background.

During those 2 hours that the screen was on, I did some browsing (45m), played some labyrinth (20m) and some twitter.

I didn't call/text message anyone today. Also no gps.

Hubs/Wifi sharing etc. has all been frozen with titanium backup.

I find this to be very light usage and still the battery is almost dead after only 2+ hours of really using it.

Idle time is great, can go 8h on about 2%, but when I actually start using it......
[Galaxy S II General] pulser_g2:
Had over 25 hours mixed usage here from about 80%. That includes

5 reboots

Wifi on most of the time

2 push gmail accounts (not much mail)

Push exchange account (no mail)

An hour or so of angry birds

Two hours of forum runner (like tapatalk)

A half minute call

Adb over wifi running most of the time

Brightness at zero, night mode via Chainfire 3D for a couple of hours

Fairly impressed and I've not even started to optimise it. Yes, I see android os usage, etc... But I find it amazing I can get a full day of over 24hrs out my second ever charge
[Galaxy S II General] chalid:
browsing the web and playing a game for 1h altogether isn't light usage. besides that another 1h display-time is quite a lot too.
[Galaxy S II General] king_dani:
in my experience with other phones, there are two battery eating processes.

1. reboots: it takes an amazing amount of effort to put everything back up, this dates back to WM5, where reboots was a fact of life, but even on N1, when things go really south, and a reboot is a must, then you easily lose 5% battery just for that.

2. cellular usage: I don't mean txt or calls, but 3G, it is a huge battery drain. but it is highly dependent on carrier. in my very short experience with US carriers, AT&T seems to be worse than T mo.

my 2cents, sorry if it does not address the issue raised by OP
[Galaxy S II General] virussnake:
lose 5% of battery on a reboot? are you nuts?
[Galaxy S II General] charnsingh_online:
It is due to the fact that LED/OLED/AMOLED are semicondutors. When we plot an I-V graph for them it is a rising curve so the voltage required to reach 0-40% is more than the voltage required to reach 40%-60% or even 40%to 100%. http://en.wikipedia.org/wiki/File:Diode-IV-Curve.svg as u can see here for the first current to flow the voltage has to be increase a lot and for the rest of the current the voltage increase is minimal. The place where the current starts flowing, take it as 0% and at Vd say its 20% of the current. u can see the voltage increase is too much for the small amount of current to flow and for the rest after the threshold voltage current increase is way more. So thats y the big difference
[Galaxy S II General] intruda119:
This is what I'm leaving today with. Forgot to charge overnight. Ill update post when I get home. Phone been off charger a little past 9 hours. But not a whole lot of use, only a couple torrents and youtube and a 20min call. Also 20-30 minutes of music in my magnum.

I also updated to ke7 last night. Definitely not the same battery experience.
[Galaxy S II General] shorty083:
For me this is light usage.

With my sgs1 I could play around for almost 4.5h screen time before it died,

using it the exact same way as described in my earlier post.

Now I know this is a more advanced phone all together when you look at the hardware,

so comparing the 2 isn't all that great, but still with the way they promoted the new screen technology,

I don't feel the advantage yet when looking at battery life.

Till I get my hands on some decent spare batteries I just take the charger with me, no big deal.
[Galaxy S II General] DarkStone1337:
Now keep in mind that the graph above is heavily condensed due to the uptime of the phone.

That said, I'm running the phone on auto-brightness and have underclocked the phone to 800mhz and set it to use the conservative governor.

I'm also using power saving mode and Juice Defender. Also using advanced task killer to kill tasks while the phone screen is off.

Not automatically syncing the phone with Google servers either. A lot of the time used with the phone was spent listening to music. I probably spent 2-3 hours worth of web browsing and game playing.

EDIT: I'm using the latest firmware, KE7 ;)

EDIT2: I'll do some battery tests today. Charge to 100% and let the battery drain using SetCPU to stress test the CPU. I'll do this on different brightness settings and CPU at 800Mhz.

Will post the results in another thread.
[Galaxy S II General] SBS_:
I guess I can post some pictures as someone with stock KE7 firmware (no root, so no frozen apps), no power managment at all and screen at 100% brightness (all power saving features off there as well).

Here's how it looks after a day at work:

Wifi: 100% of the time

Screen: 41 min on 100% brightness

Android OS: 28 min CPU time

SKY.fm: 2hours 44 mins of streaming music

FM radio: 1 hour listening to radio

Syncing/update of twitter, facebook, cnn, engadget, news republic, gmail, beautiful widgets is on all the time, most of them at a 15 min interval.

The battery is now at 46%, so it's gone down on average about 5% an hour, which I find acceptable with my use and settings.
[Galaxy S II General] intruda119:
Im finally home and after a typical day im having decent battery life. My battery life has been worst since I updated from the last firmware. With the new ke7 update im getting lock screen lag, lock screen just auto rotate is screwed up, a couple freezes, lost a bar in 3g/h+ and some other little bugs. Ill probably use odin and reflash from scratch.

Battery was at 80% when I left at 8am(unplugged for almost 10hrs)

Started poweramp at 9:30am

About 30min of phone calls

Browsed my usual sites every 1-2hr

Refreshed xda app every 30min

10 text messages thru google voice

5 text thru regular app

20mins of logmein

20mins of live holdem poker

Phone brightness at 100% Browser at 50%

wifi stayed on but wasnt connnected

3g/H+ on all day

email accounts sync every 1hr

Ive lost 60% which I guess is about 6% average an hour. It was closer to 2-3% before the ke7 update. Not horrible but better then the reported under 6hrs of use. Im at 20% now if I charged over night I would be in the mid 40s.
[Galaxy S II General] aussiebum:
Just a note for those who wanna save battery or find the brightness control isn't fine-grained enough on Android phones (or wanna keep automatic brightness but find auto brightness itself too bright) - try Screen Filter -> http://www.appbrain.com/app/com.haxor

All it does is dim the entire display by a set percentage which you set WITHOUT changing the system brightness display setting. This means it's possible to have the phone on Auto Brightness but have each brightness level to be less bright than specified by default, for example.

I have it set to 72.5% in Screen Filter and Auto Brightness on in system settings, so whatever brightness level I get is further reduced by 28.5% by the app.
[Galaxy S II General] MiG123:
cool story bro...
[Galaxy S II General] DelLoce:
Damn, I can't believe the dis-belief in here.. So a dude tells you he gets great battery-life, and you're all so annoyed you don't, that you start bashing him for commenting?

I, for one, get great battery life, too.. Take a day like yesterday.

Unplugged at 7:30

Brightness at 100% all the time (I bought the phone mainly for the screen!)

Played Angry Birds for about 45 minutes

Played Construct X for approximately 2 hours

While playing Construct X, I watched maybe ½ hour of Youtube (damn that game getting the best of me!)

Phone calls for about 40 minutes

Browsing about 30 minutes

WiFi on all the time

Auto Sync on all the time (Facebook, Twitter, Samsung, Accuweather and Google)

A small amount of texting (maybe 10 texts send and received)

Playing with Kies AIR for about 1 hour (maybe 50 minutes, maybe 70.. ;) )

Plugged back in at 00:30 - battery at 18%

This is on KE2 (KE7 isn't available yet here! ;) )

Now, I haven't done any graphs or anything. I rely solely on usage experience.. And for me, this is great as hell :) I don't mind having to plug in my phone every night - the charger is right there next to my bed anyways! ;)
[Galaxy S II General] logey18:
Batteries will always be a problem untill manufacturers produce batteries that keep pace with surging smartphones Untill then grin and bear it
[Galaxy S II General] Phytrax:
Forgive the disbelief but there is no way I could get 4 hours of screen time with 100% brightness. I may even do a little test today just to see. It's a little difficult since I'm working and use my phone but I'll have to give it a shot.

Please check your screen on time for us at the end of the day though and let us know what it says. I'm getting around 3 hours with autobright, but that's using Juice Defender and reducing the brightness curve quite a bit.
[Galaxy S II General] ph00ny:
i'm glad you guys have moved away from using % figures because it was driving me nuts since it doesn't give you a correct usage since it's a relative figure

My usage is similar to SBS_. I use mine for pandora (high quality) over 3g
[Galaxy S II General] Cooky75:
This sounds ideal, can you tell me how to configure my GS2 to get the same battery life? Ive been using Push mail, 6 hour updates of Twitter, Facebook etc, WiFi on sporadically (when i have WiFi to connect to) GPS off. Screen on auto. Im getting about 8 hours with nothing like the level of use you describe.

My initial charge (out of the box) was more like your experience as were the first couple of recharges (which i did following advice from Samsung support).

Any advice would be appreciated as your battery seems to be lasting much longer than mine?
[Galaxy S II General] DelLoce:
Sure, I will do that.. Won't be before tomorrow though, as I haven't used my phone at all today, and won't really be using it either (got soccer-practice and a trip to the movies with the better half :) )..

I really wouldn't know which advice to give.. I have, as described, WiFi on all the time and brightness at 100%, Background Effect at Movie (don't quite know if that's the right description in English, as my unit is set to Danish :) ), No Animations, 15 sec timeout and the auto screen-power turned on (I guess it's the setting powering of individual pixels and such :) )..

I have no movement-controls enabled (quite rubbish anyway, I think :) ), WiFi-sleep-policy set at "Never" and then I set the Flash in the browser to "When Needed" (this was a big deal on SGS I, don't know about SGS II)..

I haven't flashed any magic kernels or such.. :)
[Galaxy S II General] intruda119:
I've had horrible/ worst battery life with ke7. But my last test had 5hr 41mins of screen on before dying.
[Galaxy S II General] Cooky75:
Thanks, sounds like maybe i should just turn everything on.

I dont understand the difference in performance that people are having. Some with heavy use and good performance. Others (such as myself) with light use and poor performance.and
[Galaxy S II General] Phytrax:
Yes, this has me confused too. There seem to be some wild variations here. I know I watched some video using Skyfire browser today for 45min on minimum brightness and it used 31% of my battery.

Also, I made an edit to the original post. Is anyone noticing any difference in battery life or screen efficiency from black themes/wallpaper, etc??
[Galaxy S II General] Phytrax:
I think this would be a big improvement for me. Last time I checked I didn't get much over 3 hrs of screen on time before my battery died around 6pm.
[Galaxy S II General] intruda119:
That was with ke4 and prior firmware releases.
[Galaxy S II General] Phytrax:
Just to be clear, which firmware gave you the best battery life?
[Galaxy S II General] intruda119:
Ke4 gave me the best battery life. I havent had problems before ke7.
[Galaxy S II General] curiousGeorge:
So much for SAMOLED. Samsung always overhypes (or downright lies) about this tech. ("BETTER COLORS" = oversaturation with a tint + turned off black pixels). Everything else is crock -- you pretty much have to use a BLACK THEME in everything you do so as many pixels can be turned off as possible. Yeah, the screen uses a heck of a lot more than LCD to display white, so...

Also make sure the system isn't lying to you and the processor/radios aren't really taking up the juice.
[Galaxy S II General] firekyo_90:
I think that some people here are lying because with a not very heavy usage i have around 3 hours of battery life.

Anyone knows what is shared wifi or somwthing like that?it drained about 10%

If you can.get it so longer post the screenshots, here go mines.
[Galaxy S II General] dirran:
auto adjust screen power?

What is everyone's opinion on the display setting 'auto adjust screen power - save power by analysing image and adjusting lcd brightness'. It is at the bottom of the display settings.

Does this make much difference in power usage?

Apparently it was a feature on the original galaxy as well? I have also read in other forums that this setting can make the contrast funny though I can't really tell when it's on or off.
[Galaxy S II General] Locster126:
I turned it off straight away..i noticed when activated whites (e.g. browser) look more grey-ish, once turned off its nice and white again! I can get easily 5 hours screen on time with the sgs2 with it deactivated so I doubt it has a big effect on battery life!
[Galaxy S II General] leedavis:
I notice you're using JuiceDefender. Is that contributing a lot to your great battery life? Is it as good as it sounds?
[Galaxy S II General] leedavis:
Bringing this thread back on track, I'm intrigued by the question about battery used by the screen in auto brightness vs minimum. I keep mine on minimum ALL the time to get as much life as possible, but all the folks getting great battery life are using auto or higher. Is it plausible that the SGS2 is using more juice at minimum due to some defect?
[Galaxy S II General] FRLinux:
that is a very good question
[Galaxy S II General] nhat2991:
Wifi sharing is the culprit that eats your battery. If i leave it on, it would take about 10% per half an hour of web browsing. Try to freeze or uninstall it using tiatanium backup and see if it improves your batteru life.
[Galaxy S II General] leedavis:
yeah, already froze that one
[Galaxy S II General] nhat2991:
Here's my screen, the screen is on for 2.5 hrs. About an hour of watching a dvd rip avi files and browsing/downloading stuffs the rest of the time. I set my screen on auto brightness all the time as well.
[Galaxy S I9000 Q&A, Help & Troubleshooting] Joel Sjögren:
My phone has been "broken" for the past 7 days, and I'm having troubles uploading any factoryfs.rfs containing the stock /app and /media folders.

A possible workaround would be flashing as much as needed(sh executable; ls, mv etc) to be able to push the rest through adb.

Pushing the /media folder seemed to be working at first. Here's the issue: when I reboot and execute ls trough adb the /media folder is missing.

I also tried replacing the push command with "mkdir test.d". That folder was also lost on reboot.

When creating the "test.d"-folder in /mnt/sdcard it stayed.

Any suggestions are appreciated.

Another quick question that's too simple to find by googling: does your ClockWorkMod show the option to mount /system at recovery boot? I'm a bit worried since mine does. It could be related to the topic.
[General Questions and Answers] woshiweili:
I rooted my EVO a while back, wiped everything and flashed MIUI.

I am able to download FREE apps from Market perfectly fine and can update them too when needed. However, when I try to make a PURCHASE, after I click "OK" it would just give me the error message "A server error has occurred. Retry, or cancel and return to the previous screen."

I made sure my Google Checkout is all setup. I have tried searching for this issue and while many have seen the same error message, but none have the exact same problem I am having as most can't even download free apps or update as I could.

I have tried wiping cache, rebooting, you name it.

Please advise, thank you in advance :)
