Screen power saving mode? - Galaxy Note 3 Q&A, Help & Troubleshooting

Can anyone explain to me what happens when screen power saving mode is enabled in settings so far I always keep it enabled and all it seems to do is dim the display a bit and increase the battery life massively. Can anyone tell me if it's doing anything like slowing down my phone slightly with animations or something cause I don't want to be missing out, but so far that's all I can see.

it seems to dim my display quite a bit.. :/
I ended up disabling it.

If you click on power saving mode in settings it should show what you want and give you further options. It's that way on the Note 2.

Ive only checked this option in my power saving settings. Ive turned off power saving for both cpu and haptic feedback. Ive noticed it only dims the display a bit. Is there anything else that this setting does?

Looks to me like it lowers the Gamma value of the screen.
You can just as easily set the brightness to 80% yourself... Same effect

I've read somewhere when i was using note 2 that the cpu is reduce to two core only. I dont know is it true or not.

I turned it on and off with brightness at 90% and there was no difference between the two. So it just lowers the maximum brightness by about 10%.

That's the CPU setting in the power saving menu. We're talking about the screen mode setting.

Screen brightness-throttling....

Hey guys
Something that's really annoying me is my phone still changes the display brightness level with everything turned off/manual
No power saving mod
Manual brightness
Screen mod standard
Stock browser is on manual
WTF is going on. Surely others have experienced this?
How do we turn it off
If your note 3 gets too hot it will reduce the screen brightness.....
Display Settings
Automatic contrast off!

I have never seen this on any other device
It happens only 10min into use with just general browsing
Automatic contrast is already off
So is everyone happy that this is happening?
I cant believe no one else is bothered by it!!

It was bothering me A LOT but now something worse took over, the phone keeps rebooting and I've had to reset and start all over again and it's still happening. So the dimming is annoying but not nearly as annoying as not being able to use the phone at all!
I wrote about this throttling a few times here during the last days, search for my recent posts! in short: this throttling also happens when all auto brightness functions are turned off, and even if you manually set the lowest brightness! it depends on CPU load, thermal envelope and/or power-draw! I personally find it very annoying, especially because it happens also on lowest levels...

Does it happen with a full battery or plugged in?

Note 3 Low Battery Precautions - battery brightness missing

Hey, i just wanted to let you guys know about Note 3 low battery precautions.
I was using my phone as usual, as i noticed there was brightness slider missing from notification pull-down menu. I immediately checked under: settings-> device -> notification panel ->Brighteness adjustment and setting was checked!
As i became furious, i unchecked and checked that option but it was still missing. At that point i was really upset as this feature is VERY IMPORTANT for me (quick access to brightness). So i rebooted my phone and tryed again, no success. In panic i started checking every thing on my phone, all processes i deactivated (all share play and stuff like that i don't need etc etc...) all defaults than i tought some third party app was to blame for that (many apps can not be removed from notification pull down menu (unfortunately))...
Than i checked if i can adjust brighteness manually in display settings and when i saw that that function was gray (unusable) it hit me... i saw my battery was very low, 3% so i figured this is the reason.
Phone disables the ability to change brightness. Furthermore i couldn't use camera and my music app shuted down at 1% level...
So next time you see brightness slider missing from notification pull down meni, check your battery level... it sure made my heart beat a litle faster...
Cheers

Trick I use to save battery

I know some people won't want to do this, but it's something I do that I personally find helps with battery life. Nothing revolutionary, and some people won't want to but... different strokes for different folks. It's very tempting with this beautiful screen of ours to blast the brightness and get the most out of the Super AMOLED (or whatever they're calling it these days) but I've found if I'm in the same environment reading/watching videos/whatever to turn the brightness ALL the way down. Struggle with that for a few minutes while your eyes try to adjust, then turning the brightness up just a tiny bit will be (or at least seem) plenty bright. Anyway, combining that along with having rooted with Scott's CleanROM (I'm on Verizon) and my battery life has been golden! [emoji2]
Here's a screenshot of where I'll often have my brightness after doing this.

Seems really low, but I have no problem reading or doing anything at this brightness, unless I'm out in direct sunlight or something. Anyway, just my .02

This is not a trick.
Suggestion then
I use the slider on the left to turn down the brightness in mxplayer which is my de facto movie watching app.... Turn it to 15 in bright day time environments and down to 5 indoors or in dark scenarios. Otherwise the system wide default is +5 on the notification slider and auto. Able to cross 5.5 SOT easily with this much.
I have a trick to open the phone. I use the power button on the side or the home button on the front of the phone.

I've been wondering how to open the phone, thanks!
You should try out adaway! It's much more powerful than adblockplus, it actually modifies the host file. Also, try out lux if you haven't. It's seriously my favorite and most essential app. I don't know how I survived without it all these years.

[Q] Any good *working* CPU profile apps like Set CPU?

I'm on lollipop so I just noticed but SetCPU hasn't been working for a while.
I need a program where I can say
When screen goes off -> underclock to X, importance 5
When battery at 50% underclock to Y, importance 1
When battery at 35% underclock to Z, importance 2
etc.
I only want it for underclocking. The build in battery control doesn't do much and my battery life is pretty terrible when I use the phone (screen on) a lot. I've tried CPU control pro and it would only allow me to set single profile, not have it changing interactively. If anyone has any good apps they've been using let me know, I need to do something about this.
Thanks!

Since over/underclocking requires root the answer is there is no such thing for lollipop

I am rooted, on JasmineROM 5.1 (LP 5.0). I just followed the instructions avoiding the OTA and retained root. The CPU control programs I've found work for one setting, just not with profiles.
Let me widen the question out. Does anyone have any good CPU control utilities for LP or KK?
I know there is no going back one you're unrooted on LP although I've heard if you go back to 4.4.4 there is a method.

Auto Brightness Will Not Dim

I cannot get my screen to dim when in a dark environment when on auto brightness. When I go into a bright environment it will get brighter, but once I return to a darker environment it will not dim. Only way it will dim is if I uncheck the auto box in the notification shade and then recheck it or if I turn the screen off and then back on. I've waited for up to a minute for it to dim and nadda! I've tried disabling auto brightness and rebooting/powering off & on without success. Any ideas before I try a FDR?
(I'm on the T-Mobile variant and only disabled some apps with the built-in application manager ...)
FYI - I am well aware of Lux and similar apps that "are better" than the built in setting, however, I am trying to figure out why mine will not work with the stock setting.
Thanks!

Safe mode resulted in same results ... looks like I am FDR bound ?

I am experiencing this as well. I drive a lot in the dark and this is a daily annoyance.
After doing further research I found that this might be as Samsung intended it to be. I found a thread here on xda (sorry, can't find it again) where someone looked at the code for the S6 (I think) and saw it had something to do with the devices orientation. If it's flat, the device would dim if not it wouldn't - as if Sammy doesn't want it to dim while you're holding it (I assume so if your hands accidentally cover the sensor while gaming/video watching it would not dim??). Sure enough I laid my S7E on the counter and turned off the light it dims fine. Turn on the light, pick up the device, turn the light off and nadda ... screen won't dim until it's cycled off/on or the auto box is unchecked/checked. Quite a stupid "feature" IMO

Samsung just like doing stupid things to tick its users off. So many little things with this device that are stupid.
Glad I found this thread. Lux is nice, never used it before. Much better than samsung auto brightness.
Lux is great. Once you start linking the brightness to your reference, it just works.

No reason why we can't have a working auto bright built in. My damn S4 and Note 4 works flawlessly.

I agree... while I like Lux the default auto brightness should function normally
