The battery life is obviously dependent upon what services are enabled. For such a versatile device, MSFT should have a table for battery life for different usage cases. For example, for Joe the jogger who wants to use it a purely health gadget companion, he may not want the microphone, UV sensor and ambient light sensor on, but for Jane the office worker who wants to take her steps around the office and have some office notification, the GPS and gyro is turned off. These two use cases could have vastly different battery life.
