Hey all, so I just had a question about automatic brightness.
Does Automatic Brightness save that much battery compared to the level one brightness? I'm guessing that the proximity sensor consumes battery life to adjust the screen brightness, so if the lighting around you changes often, wouldn't the phone be using more battery?
So, I guess the real question is, what saves more battery life: automatic or regular?
Unless you are always on the phone, I would say that it is negligible.

I'm not so sure, this is only a theory & I'm no expert on this - but wouldn't it be dependent on the lighting conditions?
So if you're somewhere where you need your screen to be bright, that'd kill the battery quicker than in situations where your screen only needs to be dim.
But then there's also the sensor to think about, which has an effect on the battery, so if you're using auto-brightness, and your screen is dim for the life of the battery, it'd still use more power than if it was manually set to dim (no auto-brightness).
Yes!!!!

One day i was on auto brigthness and my on screen time was 2 hrs whereas next day under similar usage and brightness at lowest the on screen time was 2 hrs 35 min...
Extra 35 min by putting on lowest instead of auto

Auto brigthness always ate my battery, so now I never use it!
It does seem like auto brightness will kill your battery sooner. I used to use it all the time on my nexus one but once I found that information out I stopped.
For my sensation i just set the screen brightness for a low setting for which I could tolerate.
Although, I don't know how this happens but at times when my battery is dying faster than normal and I check the brightness setting, it is all the way up with no auto brightness checked. It has only happened a few times, but don't know what caused it, if it was my accident for which I am not aware.

I have never had an issue with auto-brightness, and have left it always on
I think it depends.
Auto Brightness will use up a little cpu but if it keeps your screen a lower brightness then if you didn't use it, it will probably save your battery life. If you find it keeps your screen brighter than usual it will probably kill your battery life.

I agree with you it all depends on the lighting conditions if you are in the sun all day your screen will auto adjust to max so you can see it better. If you are inside the screen will dim. I personalty keep mine on auto because I am always in drastic lighting conditions

This is a bug with the camera. Sometimes when you open the camera app it sets the brightness all the way up. sadly it's still not fixed even with the update.
Thanks for that information on the camera application, I thought I was losing my mind.

Just wondering, how many of you use it?
I've started using it today, and it seems good
I use it on Endymion, where there's an option to male the automatic to the lowest value, so it won't always be too high.
So is it better to use auto Brightness, or keep it locked?
I heard auto Brightness drains battery ad the proximity sensor is always alert... But that should be the same case as the Button keylights...
So, please share!

I use Auto Brightness all the time - my phone brightness button is set to toggle between Auto and 100%. The only reason I keep the 100% on there is because I use my phone as a satnav and switch the brightness to 100% when it's mounted on my car windscreen with the USB power plugged in.
Never had a problem with it, and still get reasonable battery usage from it.
I stopped caring about my battery life a long time ago. I just do whatever feels best. But that doesn't mean I leave my brightness at 100%! I like auto brightness because then I don't have to adjust my battery at night and then again when I go outside etc. etc.
Although I have heard a lot of people leaving their brightness at 40

Thanks for the replies fellas!
Yeah, i always keep mine locked at 46%, and in the night I have to crank it down when its too bright, which is a pain!
So far, so good for me!
Battery seems decent!
Would like to hear some more opinions from other guys too
Cheers

Hello guys,
I have a question.
If i turn on the automatic display light control, do i need more battery power?so, if is better to make a fixed size for light or better to turn on the automatic display light?
Thanks for help.

It depends, I have mine set on a specific level and change with a widget accordingly when needed, I've found that when you leave it set on auto it will be brighter than it needs to be and hence use more battery, but the trade off is that you dont have to worry about changing it all the time.
It's for sure if you keep brightness on auto will use more battery. I have tried it on my sensation generally I keep brightness in between 30-35% but if I keep it as auto it will use around 20% more during whole day usage. The reason is while u r in sunlight or in bright light ur screen will get more brighter to compensate difference ans use more battery.

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.
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...
