So I charged my phone overnight (from 9:14 to 5:45) with the phone off. I used the Plantronics Bluetooth 230's wall charger (the free bluetooth that came with the EVO from BestBuy). It is almost 7 am right now and the phone is at 81% with very light usage (maybe 10 minutes of GPS and about 3-4 minutes of browsing over 4G). The other thing I noticed Sunday morning aftert I charged the phone with the same Plantronics wall charger over night with the phone on, was that, in the morning the LED on the EVO was still orange indicating that the battery is not fully charged. Also see my THREAD HERE about the phone lasting 24 hours after I have charged it with the wall charger of a Samsung Rant. My Conclusion : it looks like the charger of the Plantronics Bluetooth is not suitable to charge our phones. Anyone else have experienced with this yet?
