Extend Your Cell Phone's Battery Life-3

by Ian Rowan on February 11, 2008 at 03:01 AM



Turn off Wi-Fi and Bluetooth
Wireless features such as Wi-Fi and Bluetooth may let you get your e-mail faster and free you of cords, but they're also slurping down lots of juice while they're on. The radio frequency that Bluetooth works on doesn't take too much power, but it will cut into your battery time if you leave your phone settings to 'discoverable' all the time. So, if you aren't planning on using a wireless headset or speakers, turn off Bluetooth on your phone when you don't need it. The same goes for Wi-Fi, particularly in a moving car or walking around, since your phone will use up precious battery power as it scans for everchanging Wi-Fi hotspots. Wi-Fi is best used if you're in a fixed location and plan to use your phone for surfing the Web, checking e-mail or downloading files. If you must use the data connection and are either low on battery or happen to be moving around, then use the cell phone's mobile data network (EV-DO, HDSPA, EDGE, or GPRS), which uses less power and is available over wider areas.
