不光要延长待机时间，我们要怎么样延长手机电池的寿命呢？

Hi I'm Ben from the Cellphone Broker in San Jose, California. Today I'm going to show you the best ways to extend the life of your cellphone battery. The main thing that you want to do is make sure that you don't overcharge it. A lot of people will plug their cellphone into the charger at night, and the next morning they'll unplug it. This is not really a good idea, because you are overcharging your battery. You are putting more energy into the battery than the battery was designed for. A lot of cellphones today do have little circuit switches that keep the battery from getting overcharged, but at some point those switches, you know, won't last very long. So just make sure you charge your cell phone for, I'd say, maybe eight hours at the most. Don't plug it in at six o'clock at night and then nine o'clock the next morning unplug it and go about your business.  

The next thing you need to do in make sure you're not using your cellphone battery until it wears all the way down. If you're making a lot of phone calls, make sure that you're charging the phone in-between, because if the battery keeps dying over and over and over again, eventually it will run out of active electrons in there that keep it going. So you need to make sure that you don't overcharge it and don't undercharge it. So, I'm Ben from the Cellphone Broker in San Jose, California. Check us out online,
