[Q] Brightness Usage Question - Galaxy S II Q&A, Help & Troubleshooting

Am wondering if any of you know whether auto brightness is more battery efficient than having the brightness set continually on something like a 1/4 setting??
Sent from my GT-I9100 using XDA Premium App

I personally think it uses more up so i have it set to quite low.

I set mine to the absolute minimum when I am indoors (most of the day), and Auto when I am outside.
"Auto" indoors is too bright for me. [maybe I should take off my Petzl headlamp]

It depends on YOU. If you set it to brighter than what auto brightness would set it too, then you'd drain more battery.

Umm can somone help me w/Set CPU?

So I love Set CPU and it was working for a bit, but now for some reason my profiles refuse to work. I have them enabled, but it always has "Main Profile" activated, which kills my batter. Below are my set profiles:
Screen Off 245/245
Priority: 100 Ondemand
Charging/Full 806/806
Priority: 85 Ondemand
Battery < 50 748/710
Priority: 75 Ondemand
Battery < 1 710/604
Priority: 65 Ondemand
I'm using KaosFroyo v23, but I haven't seen anything about bugs with SetCPU in it.. so anyone have any other ideas? It seems the problem is the 'Main Profile' over riding my profiles.
those are some pretty high profiles......... what are you OC to?

You mean how high can I OC to? Umm, 824 is the highest I've gone too.
Holy **** 824, lucky bastard.
Anyway, I have the same exact problem. If you want it to work you have to go into set cpu and tap the "enable" button under profiles and disable and re-enable and then hit the back button to exit. This'll keep it working on your profiles until you reboot, so just do this once as soon as you reboot.

Yeah, guess I lucked out on my phone. It's kind of a beast lol. Anyway, I tried that but it still doesn't seem to work. In the notification in the status bar, it always says "Main Profile" rather than "Charging/Full" or whatever. My "screen off" one out does work, though. The widget will show my screen off settings for a sec when I unlock the phone.
It may just be an issue with the notification bar updating.
Oh and does that say battery < 1% ? or is it supposed to be 100%?
Just so you know here's an example of how profile priority should be done
When under 50% battery, 90 priority
when under 100% battery, 80 priority
You see how lower battery needs a higher priority? This is because when you're under 50, you're also under 100. This may be your problem. Make sure that lower battery gets HIGHER priority.
I also suggest you set a temperature priority, especially with your killer speeds.

I think this was the problem. I messed up the priorities, it's a tad confusing.. oh well, this should fix it. When I did the fix in your last post, I realized that both my screen off AND my charging one did. Just not my battery.
Thanks for the help man. And for the tip about the temperature, I didn't take that into account, being that I wasn't aware my OCing was that crazy!
EDIT: Yep, that fixed it! One more question, I'm assuming that my screen off/charging/temperature profile should be set at 100% Priority? Or should it go temp profile > screen off > charging > lower battery > higher battery?
EDIT AGAIN: Okay, I think the proper set up is: temp profile > charging/full > screen off > 25% battery > 50% battery. Correct? The temp should be the highest priority so it can override the others, then charging should be able screen off, since it's pointless to lower the overclock while charging, then screen off since it is important to battery life, then lower battery, followed by higher battery for the reason you explained.
Wewf. It's worth the set up, I suppose.. and btw I CAN overclock to 844, but it's not stable in the slightest.
824? nice....... thats why I was mentioning the high profiles......... most people cap out at about 768 on this phone......I just initially set mine there and havent really tried for more
as for the profile priority goes...... IMO the temp needs highest priority.... this is the one that does the damage if not obeyed ........
I personally have all my profiles (other than main of course) set to 480/245 so priority doesnt really matter
in your last post you mentioned it being pointless to lower OC while charging..... depending on your temp profile and charging method, this theory doesnt much matter..... since on wall charger I always exceed my temp profile anyhow (which I have set to the specs in the manual 40°C/104°F)

Yeah, I just realized something pretty bad when I charged it over night.. being that charging (the 824 one) was set to a high priority that the screen off, it was literally on 824 ALL night long.. I woke up and the battery tempt was 145 D: It was fine, my temp profile saved it from going too high, thank God.
Any ideas for a good temp to set that profile at, though? It's at like 130 now, but I think that's a bit too high as well.
specs list an upper limit of 40C/104F....
specs are usually conservative (my profile is set to spec).....but I wouldnt go too far over if I were you

Alright, I kicked it down a notch to 40C.
Thanks for the help guys.
I have mine at 41.7 degrees since I can hit 40 easy.
Quick Question -
Running Kaos v23 now - since upgrading from v21, I have lost the icon at the top of the menu home screen. Also, when I go into task killer, it is not shown as an active application. Any ideas???
Thanks

Um, have you tried OPENING the app? Go to your app drawer, click on it, then check mark "Notifications" under "Profiles."
And yeah I changed the temp profile, cause it overheated during a phonecall..
Make sure it's installed. If none of your superuser permissions are working reflash an old superuser.
Does anybody have ANY good info on the Advanced settings for setcpu
sampling rate
power save bias and what not for our phones
or where we can find them ?

[Q] Minimum frequency for smooth wake up

When is the minimum frequency for smooth waking up?
When I set the minimum frequency at 128MHz, the phone take very long to response when ring up. The LCD is on, then the ringtone and when I try to answer the phone, sometimes it just not response when I slide the answer key.
And also when I wake up the phone, it react very slow at first.
What tweaking can I do to make it more smooth (and have balance of battery life)
Use setcpu and go to profile make a new one for screen off and set max/min to 500mhz it is quite good and so is battery life...
Sent from my X10i using xda premium
I suppose you are asking profiles in set cpu. For a good battery saving response set a profile for screen off to min 128 max 245mhz and on demand governor. Just press button once. You will get slight delay.
For now,I just use one profile.I set it to 245/1190 and using smartassV2
It still have a bit lag, but a lease it much better than 128/1190
Does two profiles will do better?

True Maximum Brightness on Auto-Brightness (higher than 100% manual)

For a lot of phones, auto-brightness can maximally output a higher brightness than the 100% brightness setting available to the user. Auto-brightness can sometimes output 600 nits vs. only 400 nits at 100% manual brightness.
I know this is the case for some phones (samsung Galaxy S5 for sure), but is LG G2 one of them? If so, is it possible to mod the LG G2 so that manual brightness does output the true maximum amount at 100%?
It could be risky and cause overheating, although the G2 already limits the maximum manual brightness when it overheats.

Pixel Experience Max Brightness?

I have just flashed Pixel Experience ROM to my Poco. I notice one thing immediately: brightness seems to be scaled lower. When I was in MIUI, 20% brightness seems to be enough for indoor use. Eversince I use the custom ROM, for indoor use, it takes 50% to 60% of the brightness. I wonder if it'll impact the maximum brightness by half.
please try changing kernel!

Question Sunlight mode still works after disabling

When I disable sunlight mode, the brightness still increase when in direct sunlight...
Fix?
Edit: It seems sunlight mode is activated when I manual turn brightness up to 100%. If I adjust to lower manual brightness sunlight mode don't work.
For me it is the opposite, my Sunlight mode does not work at all. My Xiaomi 11 Lite 5G NE is from 2021.10 and I cannot read the screen at all in direct sunlight.
Plus it overheats like hell also, the phone is for me not usable outdoors.
