Hello fellow listers,Does selecting a network mode affect the battery life on a mobile phone? My Nokia N91 has three network modes, dual mode , UMTS and GSM. I am on T-Mobile and I can use the dual mode and GSM, but when I select UMTS the phone goes off-line and I lose the network connection. When I select dual mode and check the network status, I sometimes hear 3G, so the phone must use this connection when available.
Can someone on the list please explain what these modes mean and how they affect battery life. As I use Talks this shortens the time between charges, and I know you can adjust the backlight and display settings. Any help most appreciated. Thanks in advance.
Best wishes, Clive pallett
