I bought a Motorola Droid last night. Now, before all the naysayers enter in, I just want to say that the HTC Droid Incredible and the LG Ally weren't right for me. I have wanted a Motorola Droid for awhile and I am still happy about the purchase. My question is this, at night when I am not using the phone, is it best to turn the phone off to conserve battery or leave it in standby? Any thoughts?
