Four Ways to Make Your iPhone Battery Last Longer

A good friend of mine had been complaining that her iPhone 3GS battery was holding less and less of a charge. When we got together at 5 p.m. one recent day, it was at 5 percent full - and it had been fully charged that morning. She had barely used it all day. The phone was apparently running itself dry simply by being turned on.

The single biggest battery consumer is the screen brightness. But it wasn't especially bright on this phone.

So I suggested that she take the phone to an Apple store to get the $60 battery replacement service. In fact, there was an Apple store only two blocks away, so I accompanied her - and found out, upon arrival, that there is no $60 battery replacement service! There's one for iPods, but apparently not for the iPhone. the rest image
