These phones so far all use roughly the same capacity battery, about 300 mah. The Moto 360 uses an outdated processor that consumes a lot more power than the newest ones. Apple is using a new custom processor and I'd hope it is as power-efficient as the best processor Samsung has. The Moto 360's battery life was improved a lot - like more than 2X - as the Motorola engineers finetuned the software (per DC Rainmaker test). How often the screen is on, how bright it is, how much the processor sleeps, how often it wakes to do things like take your pulse, how much work is offloaded from the main processor to much smaller and lower-power chips (e.g. sensor hubs monitor and store accelerometer data and pass it to the main processor when it awakens, so that the main processor can sleep more), all these make a big difference to battery life. Also how you use the watch makes a big difference, just like it does with smartphones.
My hope is that Apple is tuning power consumption, so that the battery life will be longer at launch than it is today, and that it can at least beat the Samsung.
