Thanks! Looking at my 4, which is always at "full power", compared to the 6 at full power, I see no difference. Can't compare AOD mode however.No difference on the AOD between the 6 and 5. My son has both. He prefers the SS 5 over his aluminum 6. That’s what caused me to pick up the5 even tho i have a 6 and had the 4 before. Charging and battery time is about the same as well. You just miss out on the BO which we never use anyways.
