I have recently been VERY frustrated with the charging of the phone. I have done some testing and would like to report my results. First of all I have the 2.01 update installed because I believe that makes a difference. Before the update, the phone would charge, though slowly, connected to my computer via usb. It wouldn't even have to be on the back of the computer. It would charge connected to my monitor hub. Any ways...here are my test results. There are several variables that seem to effect charging effectiveness. 1. CableCF - Factory CO - Other 2. Source SDD - Desktop Direct SDH - Desktop thru some sort of hub SL1 - Laptop #1 Direct (my home laptop W7) SL2 - Laptop #2 Direct (my office laptop XP) SWF - Wall charge unit SWO - Wall Other unit (after market wall chargers are plentiful). SCO - Car Other (after market car charger) Keep in mind these are estimates, but empirical. CF - SWF : + 1% / minute CO - SWF : + 1% / minute CF - SL1 : +1% / 10 minutes CF - SDD : -1% / minute CO - SDD : -1% / minute CO - SCO : +1% / minute CF - SL2 : 0% I will continue to update my results. But the bottom line so far is....connect to the Factory Wall Charger or Any Car Charger if you want to charge your phone. Update 12/23/2009: I've been experiencing some mixed results with charging. For a week or so the phone was charging beautifully...actually charging thru my USB at work thru a Hub even.... CO- SDH... But today it actually DISCHARGED and pretty rapidly while connected to the same USB port. My suspicion is there is an application that is running (perhaps a widget) that is pulling too much power. I have a suspicion...and will report back.
