If your like me, you check your email or have it pushed to your cell phone/mobile device pretty often. However, - If you're in a movie, an airplane, sleeping, or somewhere else you know you can't be reached, why not power off your phone completely? Just keeping it on vibrate uses its battery when you don't need it. Your voicemails and texts will arrive later when your ready to re-connect with the network.
Also please remember to keep those chargers, stereos, and flat screen TV's on a power strip. They use a fair amount of power even in standby mode. The power strip makes it easy to turn on and off without the hassle of plugging/unplugging.
