Well, but auto brightness is too dim indoors.
I usually keep brightness on 50% indoors, but when i go outside, i set brightness on max.

You had 4 hours of screen on? Then your battery life is awesome. Otherwise provide a screenshot from that.
Btw, there's a dedicated topic for this.

That's good battery. Most of us reaching 4 hours of screen should have <= 20% battery left

I don't use auto brightness but my brightness is only at about 15-20% of the way along the slider and I get over 5 hours screen on time. I'm on li8 with siyah kernel.

Problem with temperature (Screen Dimming & Throtlling)

Hello, Im using LGOG Korean version
You already know that OG has thermal throtlling issue(also in N4) , and screen dimming to 67%~
Is it possible to fix with Custom ROM and Kernel?

Interesting problem:battery

Hi friends, I have a big problem.When I shut down my s3 and open it after 8 hours, my battery discharged about % 12 -15 t,that is, my S3 is discharging when it shut down. Now i ama using Turkbey rom v17 but i have the same problem with 4.0.4 and 4.1.1
What can you say about my problem?
Sent from my GT-I9300 using xda app-developers app
It doesn't discharge when off, it's a problem with battery calibration when on. Try to shut it off and on immediately and you'll see the same.

Wow, that's super weird... Is it possible that you have too many programs running in the background? I downloaded the battery saver app and it keeps my battery from going on the fritz, might help you too
İ have not a problem with my battery life only with discharging when off ...

Battery drain on stock

Hello. I have such a problem, namely my battery drains hard :S Using 3 g internet it can't survive more than 5 hours ( I admit that the screen us turned if for maximum 50% of this time... Is it normal??
Sent from my LT22i using xda app-developers app
Also on wifi 1 hour is like 20% baterry :S It sucks because even my LG l9 has better battery time with much larger screen
Sent from my LT22i using xda app-developers app
Obviousely screen and mediaserver consume most of it.
You were playing a game or watching a video?
By some tests I did a 2.5 hours HD movie on youtube wifi drained 51-56% battery. Screen brightness,adaptive power saving mode, indoors.
My standby drain is around 1% per hour with wifi on.(no data)
So I think it is normal.

try calibrating your battery https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=lv
or reset battery stats manually thru cwm recovery.

S4 vs note 2 brightness

Hello I just was wondering I just switched from the noteb2 to the s4 and for some reason it seems the note 2 screen was brighter than the a4 and easier to see in sunny conditions. Is it true? If so can I fix it somehow? I would of thought the newer phone to be brighter.
Sent from my SCH-I545 using xda app-developers app
The s4 is a lot

I thought the disply was the same not counting the size difference. Did youvtry adjusting the brightness in settings?
Sent from my SCH-I545 using XDA Premium 4 mobile app
The s4 is a lot brighter to me what are your display settings? I did the same switch.
Sent from my SCH-I545 using XDA Premium 4 mobile app
Auto adjust screen tone is checked and auto brightness. But even at 50% brightness it seems darker than note 2. Noteb2 I left on auto and in sunny spots could see fine. Hmm
Sent from my SCH-I545 using xda app-developers app
Also all power saving enabled
Sent from my SCH-I545 using xda app-developers app
To me the S4's screen gets much brighter than what the Note 2 could do... but more importantly it's a lot CLEARER which counts a lot more for my eyes. If your concern was brightness than you should have bought an HTC One or G2 honestly (anything with an LCD Display).
What are your settings? Do u have power saving mode enabled? Does kernel or ROM make a difference? I just like to use auto

Not sure if rom makes a difference, I've only been on Stock rooted ME7 so far. I use auto with adjust screen on and no power savings. If you want it to seem brighter you should turn off power savings and adjust screen tone... I actually like the warmer tones it adjusts whites to but I can see how some people would not. You shouldn't really need power saving because the battery on this thing is pretty good, but if you want to save battery the right way just root and use Greenify and you'll be set. I can go a day and a half easy with Greenify. I've also heard that the app Lux is really good for saving power, it basically replaces the auto brightness and gives you tons of more options, but I haven't tried it myself.
