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...

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.
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.

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.
Please help... I've searched for a resolution but to no avail. I took my Desire S for a replacement screen after being dropped and becoming very pixolated. After the initial screen racement the brightness level was stuck on the highest level, with the battery lasting maybe an hour max. I took the phone back, they replaced the screen again and now, the screen is stuck on the lowest level so in sunlight, you can't see a thing.
Does anyone know if this is possibly either software or hardware related, and if it's possible to fix?
Thanks in advance
The desire S has a brightness sensor on top of the screen, left from the htc logo (as well as a proximity sensor). it measures how bright it is (daylight, night, etc) and adjusts the brightness according to the measure. It looks like they changed your LCD but the sensor is still broken.

It measures how bright it is if your setting is automatic. Then the brightness would change

go into settings->display ant see if you're not on automatic or lowest brightness. you can configure it anyway you want
Hello. Has anyone encountered their screen going very bright when on automatic brightness? I have some instances where when I turn on the phone the screen will be bright and adjust itself or if I'm viewing something the screen will all of a sudden go to 100% brightness.

My light sensor is fubar too.
Yeah my light sensor sometimes tweeks out and cranks itself to like 100% in total darkness when it should be like 20% a reboot solves it though
I find it best to keep the brightness at a comfortable level and just leave it there. The auto brightness doesn't work too well.
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.
