    I was just wondering if the iPhone brightness level affects battery life drainage. My guess is that it would but do you guys know how much?

    Yeah, it does. Probably a noticeable amount if you are playing a game for 30 mins straight or something, but just checking your phone everyone once in a while probably not a big deal.

    I try to keep mine about 50-60% brightness which seems fine and you get used to it after a while and doesn't seem dim. I only turn it to max if I'm outside and it's really sunny.

    I keep mine on 100% brightness all the time, I don't care. I want a sharp bright picture. But, yes, it will certainly drain your battery faster.

    Haha. I have to squint if it's at 100%. You're crazy. 60% is good with me.

    Amazingly. I have tried many brightness settings and the battery drain is minimal. I am using memory program from itunes that gives battery info.

    I charging my iPhone every day. Does that will make the battery life shorter?

    I keep brightness at 50%. However when I watch movies, I bring it down to around 15%. It really makes a difference in battery life.

    Does that will?

    Apple recommends you drain your iPhone at least once a month. This recalibrates the charge measuring circuit, which "learns" battery capacity.

    For most people this happens in the normal course of use.

    It won't hurt your battery to top if off before its empty.

    In general, with the battery technology used in the iPhone, maintaining your battery at full charge (always on a dock) is not good for it. The battery likes to be exercised.

    Battery service life will be reduced when batteries are charged to the maximum. I'm sure Apple sets the cutoff charge at a reasonably conservative level, but never the less, if you always charge till the Plug Symbol shows full charge, you reduce over-all life span to gain very little run time.

    Yeah, having the brightness all the way up will for sure affect the battery. I usually keep mine just below 50% so around 45% with "auto-brightness" on. With that my battery lasts all day with minimal decreases.

    Just experiment with yours and see how it effects your battery life.

    Of course it does! Just like any other device with light like cellphone. But 60% is fine with me.

    Keep mine at 30-40%. Anything more than that is just overkill. At least to me, I'm all about saving battery life.

    Plus the screen auto dims when needed. 30-40% is really not that bad. :o

    Um, sure, sounds great. Squinting here, pulling out glasses. AND I don't have mine set for auto dim. No way. Want it BRIGHT.

    Give it a try for a day and see what you think. I have mine set the same way. Once you get used to it, it's fine. Now I think it looks awkward at even 50%.

    Yeah, the only time it may be a bit dim at that level is in direct sun light but even then you can still see the screen.

    Well.. had a change of heart and moved it down to 35-40%

    Going to deal with it if it gives me a better battery life.. although the battery has not been as bad as most non-iPhone users make it out to be

    *Most* of the people who spend time on the Crackberry forums are very biased if you haven't noticed. Even some that claim to like the iPhone!

    Yeah.. I've been spending a lot more time over here ever since my iPhone arrived.

    And I moved the battery down to 30-35 and decided to just live with it but if I don't notice a significant difference in the battery I'll probably bump it back up to about 50%
