Q: Reduce motion and auto-brightness battery consumption

Hi, I would like to know some things.

 

First: does enabling reduce motion setting on iPhone save battery life since perspective wallpapers are being disabled when Low Power Mode is on?

 

Second: Does turning auto-brightness off and keeping the brightness about halfway use less power than having auto-brightness on, thus allowing the iPhone to constantly check our surroundings and adjust the brightness?

 

Thanks!

iPhone 5s, iOS 9.3.2

Yes but only a little as you said.

 

Also, the fact that it's constantly checking for the level of light in the room doesn't consume battery itself?

The light sensor usage would be minimal at most, lost in the "round off". The items that consume battery the most are in the link below.

    To the first question, while I cannot tell you with certainty, yes reducing motion should conserve some battery life.

     

    To the second question, it depends. If auto-brightness is keeping the phone on a setting higher than halfway then it would. If A-B is adjusting between a low and a high level, then likely not. I keep A-B on all the time and have no issue with battery life but if I am outside it would be a trade off between being able to read the screen and conserving battery.
