WMLongLife is an application that installed in my HTC HD2 long time ago but not being used until now. My HTC HD2 battery runs out a little bit fast lately. Maybe due to frequent Internet surfing or battery quality degraded (after 4 months usage?) or poorer signal from my operator ~ Celcom. WMLongLife is an automatic 2G/3G band-switching solution. It will turn on 3G when application like Opera Mobile needs to access Internet. And turn back to 2G mode when no needed. Note – 2G uses much less battery and usually generates less radiation than 3G.
