I don't see how manually putting the phone to sleep really saves much battery. The min default setting is 15 seconds, but a minute seems reasonable to not have it accidentally shut off while reading a long email or web page. But I've gotten 12-13 hours of battery with the screen on ALL DAY (at min brightness, which is perfectly fine indoors), so those 20 minutes you're saving don't seem worth it to me as your phone should generally make it thru the day with no problems if it's always sleeping when not in use.
I'm still searching for what I consider to be the ideal set-up: Phone shuts off WiFi, GPS and Bluetooth and then sleeps when placed on a table. Phone turns on all that stuff and "wakes" - unlocked to my default home screen - simply by picking it up OR if I receive a text, email or call (in those cases, it wakes for a minute to let me check it out). This is how the phone SHOULD operate to maximize battery with minimum hassle. It needs an alternative or second "sleep" mode that doesn't require unlocking and/or hitting a button to wake. I understand the purpose for when you are on the go and/or it's in your pocket, but at home and the office I want the power savings of sleep mode without the hassle of waking and unlocking.
