I'll post it now so that I can refer to it later on. Battery life greatly varies between usage, signal strength, apps wakelocking (or not), display brightness and what not. I've set it up to save power as much as possible, but there are parts of the equation that I don't control. So be wary of that before you say X or Y wastes more or less battery life (or the usual erhmagherd no deep sleep as if I removed it... lol). I don't have any numbers about the improvements I've made, but they are pretty much in line with every device I've worked on. If you have my app the Power-Saving perf profile is a winner and helps tremendously if you really need the extra screen on time.
