Is this true that when I turn on screen rotation option the phone will drain battery much faster?
Maybe not "much faster" but it definately drains. Any time you processor draws power for any task, or graphics redraw, it uses battery.

I like using the render effect night mode during nights because the screen is too bright in the dark even with the dimmest brightness.
will it have a bad effect to our phones when used for a long time?
Sent from my SGH-T959 using XDA App
Is render effect like screen filter?
If you are using the blue effect for an extended period of time then maybe. The blue subpixel has the shortest lifespan compared to the other subpixels colors so the brightness of your screen may decrease a little over time. This is in the case that you are using blue only for a few hours every day.
Red should be fine since the subpixel is theoretically supposed to last fairly long. It also consumes the least power after black, but makes the screen look pixelated due the pentile subpixel arrangement.
what about the night mode? It's a little brownish.

No dude!
It is recommended for battery savings. The red mode is the best for battery.

I use the app called screen filter and have it set at 25% for night time. Battery life appears to almost double it seems.

folks
can someone elaborate on this a bit more?
do these kinds of screen filters need root access? (my gsii is not rooted)
i ran in to some kind of torch light app on the market and it offers a red color cast for saving battery life too. is it the same as what is being used to save batt?
thanx in advacne
hi,
is there any ways to rectify my problem?
i have flashed arhd 1.1.8 rom with stock kernel and recommended radio.
But when i use currentwidget to monitor my battery consumption, i notice that it draws 400-500mA when i'm using, and 200-300 when idle.
is my battery miscalibrated? or is it because of faulty battery?
TIA

First things first I'd recommend that you fully charge and then recalibrate your battery, assuming that you're root there is an application called battery calibration
personally I'd also suggest that you drop current widget and start using battery monitor widget, I find it's more accurate and a better product.

The way to test phone battery consumption its to turn off wi fi, bt and gps, auto sync to off.
Leave it for a few hours with screen off and then review the log.
The screen will be the biggest consumer of battery so don't use auto brightness, you'll only need about one quarter brightness setting, only in direct sun light is a higher setting required.
When you use the phone expect the battery to fall.
You should really take the phone through a couple of full discharge and then full charge cycles before judging.

Ensure that the always on mobile internet setting is off (setting, wireless, mobile, always on.....) and that mobile data is only on when you're using it.

Does removing bloatware drain battery?

No.. helps battery life just freeze your the boat in your app settings.

disabling bloat helps keep less apps using cpu resources therefore less battery drain be careful on wat u freeze though

And why would you think it drains more battery?

Well because i froze a ton of samsung and att bloatware and ive seen no improvement on my weak short battery life. I mean 4:30 hrs on battery with 3:01 screen on and im at 15%.... maybe the system is looking for the disabled apps??? I dont know..
Sent from my SAMSUNG-SGH-I747 using xda premium
3 hours of on screen is why your battery drained. Doubtful it's removing system apps.
Sent from my SAMSUNG-SGH-I747 using xda app-developers app
I've seen really varied battery life. The screen is the number one battery drain on our phones so I use my brightness as low as I can get away with. Monitor your battery life day to day and see if screen percent battery usage even when used for 3-5 hours should start to show closer to show 20-30% of your battery usage vs the likely 50% or higher you may be seeing now. I use a third party app to lower brightness even below our normal GS3 brightness when I know I'll be surfing or using the phone an extended period of time.
Common battery conservation knowledge consists of simple things like disabling GPS, WiFi, and Bluetooth when possible. Limit or turn off sync when uneeded. Turn off led lit touch buttons if you get used to menu and back where they are. Turn off sprint network optimizer (sprint only) it seems to scan networks too often leading to too much battery discharge for me. Turn location services off if not used often certain ones not GPS effect battery too. Uninstall bloat which you did. Turn options in apps off not to sink.
Check battery usage during screen off and idle and make sure your phone is sleeping. If you have a sleep bug the phone is not shutting down cores and lowering speed while not used leading to multiple hours of battery life lost. I turn off vibrate and haptic feedback off except where I can. If your rooted take control of your cpu and when not needed clock it down yourself. If your browsing you may not need max frequency. 1ghz core or less is good to save power while just casually using the phone.
Just a rant on what I've had success with. No pic but I have had success getting 24 hours between charge with heavy use like 6+ hours screen on if I was really conservative. Most days of heavy use as long as I didn't use a giant overclock I get 9-10 hours between charge.

My favorite brightness widget for quick access and free on play store.
https:// play.google. com/store/apps/details?id=com.haxor
The great widget that's free on play store to adjust your brightness lower than current device brightness in a percent form. it can go 0-100% below your lowest brightness level or even below your highest brightness level if you prefer... as its based on your current set device brightness and is accomplished by using a screen overlay I believe. Adds a little lag when enabled but saves you the power when needed.
Remove extra space in address for Play store links. Admins hope link okay.

Fixed the links for you. Once you get 10 post you can link don't just spam for post tho.. at least attempt to add to the thread when you do those 5 other post.
I might just check this out as well. The built in SGS3 brightness thingy is garbage so I have it set on max *I still get 4hours of screen on for max brightness tho haha*
Edit: Those apps are not what I thought they are.. I thought it was a different auto brightness thingy but its not that still useful I guess if you want to go crazy on battery.
3 hours screen on = good

3 hours of battery life is still decent anything lower than that I would be a little worried about it.

Okay thank you kindly. I know much less than anyone here. I am new to this world and new to Android.
Those apps are not new brightness control as you have stated. ofirst one is a simple widget to change brightness from home screen so its just a shortcut. The second a screen overlay that doesn't get in the way of using apps and darkens the screen beyond minimum brightness that SG3 or any phone has. If a user does not need lower screen brightness than normal than the above apps are not going to be useful. Thank you for fixing links. I hope I can add to threads and around.
Like you I would love to see an app that creates a custom auto brIghtness function.

Thanks this looks great. that's what I was looking for in first place. Ill give it a try. That's definitely better yet.
A guy commented on app there and said useful info as follows which Ill try out myself just thought it was also interesting.
"On "automatic dynamic" mode- behaves buggy & erratic. USE: "automatic periodic" with updating at 5 sec intervals. Now works well. Set backlight zero to 10. Sample lux/% settings: 10/-55%, 100/10%, 500/35%, max/100%. Try it. Be nice if widget also showed Auto & %." -Heath
Edit: After trying the above app it easily replaces both apps I posted. Thanks jmorton10 for posting this great app.
Edit: After using all the apps. I found Lux can create lag in the touch interface and browsing etc just like the app"Screen Filter" I posted. On screen filter it causes lag when enabled and for some reason Lux also does this to my phone. Once I disabled and restarted the lag was gone again. I don't have to restart phone for Screen Filter just turning it off with a single button press fixes it. Lux has more features and actually makes a custom auto brightness profile. The free version is fairly limited but has enough to still make a fair brightness profile. Given the lag which is likely on just a few handsets is something most of us saving battery can deal with. Between all the apps I guess it depends on what you need. Lux is a top notch software but the free version is fairly limited vs the free brightness widget and screen filter but has no auto-brightness customization. The lag on Lux was not right away and was exactly like the lag in screen filter app so both must have issue in way the below normal brightness is overlayed over the screen. The paid version is likely very in depth.
Thanks for the app suggestion again.
Thanks for the input. I bought the onite 3800 mah extended battery, but im changing it for the qcell, or hyperion.

So, what exactly does Power Saving mode do? Have seen reports for the GS3 that it lowers clock speed, others that say it disables a core, so obviously there is no consensus as to what it does. It's not that I need it, this battery is beastly, but I am curious as to exactly what it does.
When you click power saving in the settings (instead of just switching it on) it tells you, but it dims the screen and changes the browser to a blue hue to reduce battery drain and also turns off haptic feedback, it also limits your processor speed to 1.1ghz instead of 1.6ghz

I use it at night alot because it dims the screen. i notice about 30% longer battery life...i just recently netted 50hrs of battery life with 7hrs screen on. still had 12% remaining!
Is it bad to turn the power save mode all the time? And what about turning it on while charging? And what is the best battery percentage to turn it on?
Any help would be appreciated.

When your battery's low. It usually turns itself on at 20%. Least on i737 is not going to hurt anything. Just cuts off cell data and such to save power

No problem to keep power saving mode always

The power saving mode only reduces brightness of your display slightly ...and turns off some of the radios that are inbuilt...also it reduces the cpu usage...these all contribute to saving battery...or at least allowing it to last till the last possible moment..
Having it on all the time...even while charging is no problem at all...it has no affect...
but since it does reduce cpu power... there is a chance of lag in some games and stuff like that...i say it with personal experience... also if you are always checking benchmark scores...it will reduce....so you can use the power saving mode wisely....once again..no harm in using it all the time hope this helps
Im always on power saving mode cause, well.. I don't notice any difference at all whether it's on or not.. Except it kinda improves battery life. I only disable it whenever I'm playing heavy games
Sent from my GT-N7100 using Tapatalk 2
ther is a difference when turning on/off the power saving mode..it limits your CPU frequency to 1200mhz rather than getting 1600mhz on your CPU..try installing Cool Tool from playstore so you can check..
