Like someone else said, 11 mins after being taken off the charger, it will show 90% but it's really more like 91-99%. Motorola only shows 10% increments. (Circle Battery Widget fixes that though). So I don't think your battery is discharging too quickly..
You can try turning off the "Use Wifi to find location" or whatever it's called, in your settings (and GPS off too). That saves my battery a ton, if I don't allow it to use wifi to find me all the time (and I can just turn it back on only when I want it). I notice a huge improvement the next day after turning it off. However, could just be in my head, like a placebo effect sort of deal.
