Screen Brightness and battery - HTC Desire S

hi all, I want to find out whether having the screen brightness on 10% really saves battery or is it better to have it on auto.

It would be easy to test this yourself.
Set it to auto for a couple of days, make records.
Set it to 10% for a couple of days, make records.
You could also try a battery monitoring widget which shows mA consumed. These are great for this kinda thing.
To your question, I'd say it depends on ambient light. If you're somewhere where auto would set the brightness higher than 10% (read bright light situations), it will consume more battery. If you're somewhere dark, it could be that it will use the same. I keep mine set to 10%, and adjust as needed. I've found that auto often sets the brightness higher than I'd like to have it (I've got an SGS2, but I'm also very battery conscious).

I've found that the auto-brightness keeps the display much brighter than it really needs to be during operation in low ambient light (e.g. indoors), so I generally leave mine switched to manual and turned down.
Subjectively, keeping the display dimmer like this seems to make the battery last much longer, although naturally you'd need to do tests to have proof! Certainly well worth trying.

can change in roms eg cm7.1 for auto brightness

I use Lux. Works very well on my stock TM-UK ROM.
Possibly the more effective software I used to increase battery life

i made the same experience with the auto-brightness. I also use a widget which lets me change the brightness on my homescreen, it's quick and very useful.

Who Uses Auto Brightness?

Who here uses the auto brightness on the captivate? I noticed that when i have it checked off, it makes the screen dimmer than it used to be. When the screen is dimmed too far, i realized that we're not taking advantage of the super amoled. The colors just look average when the screen is dark. I checked the auto brightness off and the difference is night and day. I have the brightness around 40 percent. my only question is, will my battery take a HUGE hit from this?
btw, what exactly is power saving mode? i originally thought it was the same as the auto brightness but im guessing im wrong.
I don't use auto brightness on mine. I usually keep it all the way dim and my batter lasts wonderfully long. And when Im trying to look at something that i think needs to be brighter i just slide my finger across the notification bar to the right. To me power saving mode i think just adjusts the brightness based on the colors of the image it is displaying. I've had it on since I've had the device though so i don't know exactly how it works.

I keep mine on the dimmest setting since it still looks great, and even downloaded the screen dimmer app recently. I've never used anything higher though... I take public transit and actually feel conscious about how insanely bright and vibrant the screen can be to people near me and never turn it up.
When I'm outdoors during daylight hours, the only way to discern anything on the display is at full bright. Yes, there is a big hit on the battery. I get about 4 hours, but I have a spare battery at the ready.

Auto brightness or set to specific on Skyrocket...

...curious, I set my brightness to at about 30% or so. Some people use auto brightness.
But, do you think auto brightness uses more power (since it is forced to monitor the device) to use this feature?
yes I believe it does, on gb it was constantly flickering bright and dim. If u want custom auto brightness levels, I recommend the "lux auto brightness" app. I use it, and its amazing
Thanks for the suggestion. I'll look into it...
I do hate that when I'm outside, if my brightness is set to 30% or so, I can't see anything on the screen. It is those little things that I miss from iOS from time to time. And of course you can't set the device to 100% or so brightness, because then the battery most certainly would not last all day.
Unless I'm in total darkness I use 100% brightness all day every day. But in the dark it hurts my eyes so I gotta turn her down a little. Battery is still pretty kick ass too:thumbup:

It is funny how in BestBuy they have all the devices on 100% brightness. They do look nice; then again they are connected to power all day
Even yesterday I was playing with the Note. Yes it is impressive. But the size; imagine holding it to your ear while on a call. Exactly...
I have not had any Android phone that I liked the auto-brightness setting on. My wife's Inspire works the best out of all the Android phones we have had.
On the SkyRocket the auto setting always seems to bright for me.
I like Brightness Profiles. You can set what ever levels you want (or quickly turn on auto-brightness). I have mine set up at 4%, 8%, 12 %, 25%, 50%, 75%, and 90%. I have a shortcut on my home screen for quick access.
How much the screen brightness hurts your battery life depends on how much your screen is on, in addition to the brightness level.
Just turn off auto brightness. When you need to adjust it just slide your finger across the notification bar at the top of the screen ..side left dimmer, right brighter that's what I do.
Ya its seems like a lot of people don't know about that trick

I find it cumbersome honestly, I find lux waaaay better
I keep mine @ 100% unless it's way dark. Still get a full day of battery life under normal use too. It's really user preference.
I use juice defenders auto brightness feature. Its better then the one in the settings because it can go way under the min. brightness so at night it saves a LOT of battery since the display wastes the most battery..

I have mine set to 100% all day. I paid for this thing and I want to see it in its glory EVERY time I look at it. Why should I punish myself? That way I'll never have to post a thread such as this one.

That doesn't work for me with the second ICS leak. It did in the first leak.
I agree, it doesn't appear to work with the second ICS leak.

Does auto brightness really use up more battery?

I don't mean that in terms of how bright it sets the screen, but in terms of polling the light sensor?
Eg if I set my auto brightness to always stay at 50% brightness (as an example), would it use up more battery than just putting the phone on 50% fixed (light sensor disabled) ?

The drain will almost all be down to the screen, not the light sensor, so in your example I would expect near equal battery use. The problem with auto brightness is more that the values are a bit on the high side for each light level. As an example, if the phone sets it to 50% based on the light, it could easily be say 40%.
I have the subjective impression that the OTA to 4.0.4 also decreased the autobrightness levels a bit...
Before I always managed brightness manuallly to get a screentime over 4 hours. Since the update it is possible to get over 4 hours with autobrightness...

Battery life horrible? Try this!!

For all you guys who need the edge on battery, and dont need alot of screen brightness, like me, then try out this app on the play store called screen filter. (I am not affiliated with this in any way, I just like the way it works). What it does is apply a "film" over your screen going even lower than android screen brightness. Perfect for office setting (like me), at night when brightness is too much (laying in bed playing a game), or where bright lights might not be wanted (movie theater, work, etc...). I personally love it, I use it usually at 75% with the android brightness off, and everything is still visible, just that extra kick of brightness is gone. Sometimes I go down to 50%, but that gets me seeing my reflection just as well as the screen itself...
It also helps to keep out them creepers that try to look at your screen while sending private texts, pics, etc... Helps keep wandering eyes off of the fancy 4.8 super AMOLED display!
You can add widgets to custom brightness settings to suit yourself, I have 4 right on one of my screens that I use frequently!
I recommend this app to anyone and everyone!
It wont let me post links, but if you search "screen filter" it should be the first app. The logo has a white rectangle outlined in orange with a grey circle in the corner. Not too hard to find at all.
I'm almost positive that screen filter won't increase battery life. I think the phone basically "thinks" its still at a higher brightness than what you see, so it really doesn't improve battery life. I may be wrong though but I remember seeing that when I used it on my droid x.

OLED pixels produce their own light (that is, without a separate backlight). Colors are made darker by dimming pixels. If the app makes what's being displayed on the screen darker, it should be helping battery life. The same reasoning applies to saving juice with dark backgrounds and inverted apps. It just only works on OLED screens and not backlit screen types.
Okay. I wasn't sure if I remembered correctly. Thanks!

Lux Auto Brightness works a little better, in my opinion. It can go less than the screen's brightness without the filter look.
Hi guys,
A friends uses auto brightness, and only speaks ~ 20 minutes / day. A few browsing, reading e-mails, games, just got him at 2 days of usage. Not bad in my oppinion, but certainly they should have improved the battery.
To me it seems like the battery life is longer. My first week of use around 9 or so it would be in the red, but using it throughout the day, at 9 tonight it sits at 37%. Yes it will vary depending on use, but mine has been on battery 15h 30m and screen is only 18%. Cell standby is 30%, and chrome and facebook are each 11%. Everything else is quite small compared to those main apps used.
It seems to me it is helping, but it may not idk. I will continue to use it unless I run into a major issue with it.

+1 to Lux. Set your own brightness levels for various light levels. It can make the brightness very low, almost not visible.

Anyone have some good values for the automatic brightness settings? I just want to go dimmer across the board compared to stock but I'm confused with all the options so far lol

Lol two days of usage and you think the battery needs to be "improved"??
How good does it have to be before people don't complain about it??

I would be happy to get 2 days of usage... I probably could get 1 and a quarter, but I charge mine every night to be safe. Really varies on how much I use it during the day. Some nights I plug it in with 10% others with 50%... I know its not the best for the battery, but I just plan on getting a new one when this one takes a crap. I have a feeling this phone will be around long enough that the option will still be available

That won't hurt the battery, I plug mine in every night also.
Thanks!

What I would like is for my battery to last just *ONE* day. It doesn't do that. I don't mind charging it every night, but I'd prefer it last the day without me having to either charge it or switch batteries.

nice find
nice find on this. i use inverted apps, and i like the way this works

Recommended brightness setting - balance of brightness and battery life

Out of curiosity, what brightness are people using for their phones. I remember reading some test on older phones where there there was a definite cutoff where reducing brightness didn't equate to major increase in battery life. I'm currently at 40%, without adaptive brightness (it started to annoy me as it seemed to be a little unstable at times...noticeable shifting that it looks like others have experienced) , but curious if going slightly lower (30% or 35%) is worth it to maintain a nice display while improving battery life. I love a clear bright screen but also value battery life so interested in good balance. Thanks.
I'm curious about this as well. I run mine at 25% but do keep all radios on.

I use adaptive and just set the brightness to whatever I'm comfortable with. That usually means somewhere around 26-30%, sometimes turned up a bit in dim rooms as it can auto-dim a bit too much. This isn't about battery though, I'm just more comfortable with this brightness than with higher. Not studied the effect on battery life.
I keep mine at 25% with adaptive brightness turned on. It gets dark enough at night and bright enough during the day to be comfortable on my eyes in both situations. I have no idea how it affects battery though.
