I am very impressed with how long the iPhone battery holds a charge. But, I am always trying to tweak things and extending the battery life of mobile electronics is something I do often. Here is a little trick that will really extend the life of your iPhone battery.

This might seem logical and basic, but you’d be surprised to discover the number of people who didn’t think of this. From your iPhone home screen, click settings, brightness, and then turn off auto brightness. From there, scroll the brightness all the way to the left. Doing this makes your screen much darker. However, it really isn’t too dark. You’d be surprised how it looks once your eyes adjust a little bit. The only time I increase the brightness of my screen is when I am using my phone in direct sunlight.

Here is a screen shot to show you how to make the brightness adjustment.
