Well the first 2-3 days I was having Horrible battery usage. Yes I was using 4g, gps (Trapster app is AWESOME) and data background, sync, etc etc etc now I turn off 4g, wifi, gps, etc like everyone else here but I still have a few more questions about battery usage. Currently my Android system is 57% usage my 2 biggest usages is that and Cell standby now when i go to setting>app>running services I have the following running: Calender (Obexservices) - wtf is this, do I need it on? I dont use calenders Calender (ConnectivityService) - same as above, do I need it or forcestop? Voicemail (CM_Service) HTC DM (HTC DM services) - ??? HTC IQAgent - ??? com.smithmicro.com (DMServiceApp) - ??? Swype + Pocket Empire --------------- I have gone through every other settings and turned off most background data running stuff off, syncs off, roaming off, so what else can I do to tweak my baterry usage.
