Hey xda,
I'm curious as to what you all use for your screen brightness settings. For the duration of my ownership of the fascinate, I've kept it at the lowest possible setting. I'm wondering if that's really doing that much for my battery life. I'm contemplating turning it to auto.
What do you guys think about screen brightness as it compares to battery life. Is the screen not lit with LEDs? If I'm not mistaken, a typical LED could run for like 40 years on a single AA battery.
I am on auto with GPS, Data, and sync on all time. I use it pretty heavily I would say. Nothing like hours at a time but 15 min here, 5 there, 10 there. I get about 16 - 18 hours out of my phone.

Thanks for the reply. I was wondering if I should keep GPS on too. I mean as long as I'm not actively using it for navigation, is it really going to be draining any battery life?

Yep...but i'll sacrifice in favor of beauty for a loss of thirty min. Of use
how long an LED runs on a AA depends, some might run a day (not 40 years), others less than an hour, and the most powerful ones need multiple D batteries just to turn on. these phones have a SAMOLED screen, broken down into: Super Active Matrix Organic Light Emitting Diode. the important part here is the organic. instead of having a single, or a few LEDs behind or around the screen, the screen uses an organic (not organic like the meaningless buzzword, but no ****, it's organic cells) compound for each colour. these organic compounds produce light when electrically charged, and only when a colour is displayed. this gives you the possibility of a truly infinite contrast ratio, and brilliantly rich colours.
I leave mine on auto.
Was using the lowest setting, but I'm now using auto setting.
I normally have it at its lowest setting unless I'm outside. I used to have it on auto, but it didn't work exactly like I wanted. Now that the notification bar brightness feature was added with Froyo, I just use that to adjust the brightness without having to open up settings.
As long as you don't have the screen on for minutes at a time, the difference between automatic brightness and the lowest setting is minimal. I switch to automatic for days that I tend to be outside a lot, but I normally leave it on the lowest setting because I occasionally go on binges where I read the news when I'm bored. If I don't do that too much and don't have any phone calls that last over 15+ minutes then I get about 48 hours of battery life on JT's AOSP ROM.

What gives you better battery life - keeping it on Auto or setting it manually to a lower setting?
People say auto brightness affects battery life because it utilizes CPU power. I call shenanigans on that though because it will use very little CPU power... I vote AUTO.. cause if your out in the sun and your settings are set to low... You are just going to tweak them to accommodate your needs.

I have mine set on auto, but it doesnt dim or brighten up.
Bet it does! just when it needs to brighten and dim, you never notice. I thought the same thing until I played with it for a while thenI noticed it working.
auto eats more power, but it does what it needs to.

It uses more power to make the display brighter. Think of it like those 3-way light bulbs. The lowest setting is like 25 watts, the middle 50 watts and the brightest is 100 watts.
There is a widget that lets you change it manually between 33, 67, and 100% brightness with the touch of the button. I have that on my 2nd screen (along with WiFi, GPS, etc) and keep it at 33% most of the day every day.
I use auto due to ease and I easily get through the day without charging. I do use manual if I am in a dark room b/c auto just doesn't seem to dim the screen enough.
I like the 3 setting Brightness widget also. I like to set it where I prefer, didn't really care for auto. Don't know about battery savings with either one.
Is this a stock brightness widget or do I have to get it in the market?
I keep mine low...
24 hours later... 55% battery.
I use battery level its a small widget to change every 25% its great my battery is amazing Im at 58% after 12 hrs using 25% the brightness level and of course WiFi always on and turn in mobile network when I leave the house which saves me SO much battery
Sent from my PG86100 using XDA App
I always run mine at 100% brightness. I don't care about battery life. I prefer a bright screen.
Using a widget is probably no bad but I just auto , come on the phone was made with the sensor for it and it doesn't use much battery unless you have it a t 40% or lower all day long and struggle in the sun. I been using in auto since the iPhone I changed it for Android but i went back to auto cause it waste time just to change the setting everytime and annoying too

It's a stock HTC Widget, but they also put powerpanel in there. I just think the HTC widgets look nicer.
I wished the auto brightness function had user-defined options. I agree with it being way too bright at night.
I have been using the 3 setting brightness widget/button. Usually always leave it on medium till I'm at home with the wall charger then I use max brightness.

The best widget I've tried is Brightness Level made by Curvefish. You get easy access to preset levels, a slider to adjust brightness to any level, and enable or disable auto brightness.

it would be nice to find a widget that sets a daytime and nighttime level. i use tasker but i think it's just too big of a program for just this one little thing.
I shut off my auto brightness off yesterday after a few hours to see if it made a difference and set my level to 40%. I don't know if it was a fluke or not but after 13 hours when I plugged my phone back in to go to bed, I was at 63%.
That is a huge difference from what I have been seeing. I am going to see how it turns out today with the same setting but I must say it is looking pretty good so far. After 2.5 hours with some texts, a little web surfing, some theme changes and emails and I am at 93%.
I will post back my results later tonight. I am also using power control plus which has a brighness widget that you can set to a percentage for each hit. So in case I need fill brighness, one click and I am there. Another click I am back to 40%.
I'm not typically on the phone for long amounts of continuous time, just to text then i turn the screen off (the display is on auto brightness), and i'm getting half a days battery, and display is showing up as using about 70% of my battery at any given time. Any ideas on what could help or anything? Any help is much appreciated
I've had the same thing since day one. What I always do is turn the brightness down when ever I can. It actually helps a lot. You'll notice a difference

How often you sync your emails? every 15mins?
Also try UC , UV and turn your screen brightness to as low as you can.
I hardly ever sync my emails, i have it to auto-sync but i never open it. and whats a good kernel that allows me to do that?

if you never change your email sync setting, it is sync every 15 minutes I believe and that sure use a lot of juice.
Really you should try UV and UC and don't use force dual core if battery life is most important to you.
do you know what kernel would allow me to do this?
I take it most of you run manual w/ the screen fairly dim. I have had it on automatic. Im curious at about what percent auto hovers at. I know it auto adjusts but it probably has a general range it stays at - just curious if its like 35% or 55%.
What Percentage do you guys keep the brightness on for the best combination of battery life and visibility?

I thought we've been over this. A high screen on percentage doesn't mean youre screen is killing the battery. It means its using the most amount of overall power. Technically that's a good thing. It means the rest of your phone (syncing, android processes, games, etc. Etc.) Aren't running wild in the background while the phone is asleep.
I'd be more worried if your display was only using 40% of the battery!
Turn auto brightness off.... It's too simple to pull down quick settings to change it that way,
Find an app to see running processes and services,might see stuff listed you have no idea was running.... Don't force close anything or mess with anything just use it as a refrence and find out if u really need the app or not, I use titanium back up to keep apps that I use just not to often and just restore them quickly use it and delete it.... I've seen a lot of games running in the background to give notifications and stuff, could be a lot of things... Best soulution to save batttery.... Buy a spare lol

I had installed battery monitor and noticed, that when using phone in internet plussed in usb for charging - BM shows -430mA!!! Is usb port so weak? why phone consume so many power?
The screen dims and changes brightness by itself so much I am contemplating just turning it up and leaving it.
Any thoughts to this, and does it drain your battery super quick?

If you plan on disabling brightness just keep in mind if your an outdoors user or indoors user, the lighting around you will play a key roll on what levels of lighting you decide to have.
Personally I have the Automatic setting enabled, but I keep a widget (via widgetsoid) handy so I can disable it when I want and how I want on the fly.

Max brightness will definitely have an adverse effect on batt life. I personally keep mine at about 40% which is fine except when im in direct sunlight.

I know what you mean, I tried doing the same because I got sick of the brightness changes all the time, but after a couple of days having to adjust it myself or compromise on batt life, I decided to go back to Automatic settings... In my life I go to much outdoors as I can spend hole days indoors its what ever happens, happens so I decided to stick with the annoying setting other than being annoyed by having to set it myself.
Screen brightness is the biggest contributor to battery drain. I keep mine as dim as possible at all times. I've unfortunately become quite OCD about it.

I'm the same way. But the problem I have with this phone is that the more dimmer I make it, the more uglier the whites become (which I have become OCD about).
So I have double OCD working against each other and my brain is going to explode. That is all. Carry on.
Ok; the phone has been out a few months. Anyone's opinions changed?
I generally keep screen auto-brightness OFF, and set it to about 60% to 70% brightness static. When plugged into power to watch video, I go to 100%.

+1 for Auto and a widget. Most of my use happens at the extremes - OFF or 100%, so this provides easy switching.
I keep mine down around 10%, and only use autobrightness when outdoors

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.

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.

Screen is great in full sunlight. You get max brightness if you turn off auto brightness and push the slider all the way to 100%. Guarantee you won't have an issue with that.

I do sometimes miss the AMOLED screen from the S4 only for the Blacks though.

I'm coming from an HTC One M8 and idk, I'm just not sold on the display yet. Maybe just my eyes. I do find that auto brightness is always too dark for me inside.
+1 for LUX app, I have it in every phone and tablet in my stable, but...
I find the LUX auto setting to be much too aggressive in dimming the screen under most conditions. I often have to force it to add 30% or more to the auto.
Agree with post above about missing the inky blacks of an AMOLED screen. The blacks are the only complaint I would make about this beautiful display.
I like it @ 70 no Auto, with color correction on and the circle covering just a smidge south of center on the camera icon on the screen that you use to calibrate the color correction.
50% and auto.
For me, anything less that 80% looks awful. Yes, downright awful! At 80%, it looks great. On my G2 it was 70%, but the G3 needs more to look clean and bright. I'd rather have to charge the phone 20 times a day than suffer with dimly lit screens. Sometimes people spend more time trying to figure out how to save battery life than they do using their phones. Enjoy your phones people, and stop suffering over battery life!
That said, I do get a tiny blip of dimming when switching apps or screens. At a solid 80% it seems to auto dim a tiny bit during normal use. I think this is some sort of throttling function that is normal with the G3, but it is minor annoying. Some people had done some overrides to this but I can live with it.
