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.
By default, Windows Mobile HTC HD2 will have auto selection on the network band ~ 2G (GSM) and 3G (WCDMS/UMTS). However, I don’t have a strong 3G HSDPA signal at my place. And it will switch back to EDGE or GPRS whenever 3G signal dropped below 1 bar. This is really annoying. Is there a way to make it stay at 3G HSDPA permanently? Yes, here is the step by step guide to fix it.
