There's something afoot, because Motorola has marketed the Moto 360 as having a 320 mAh capacity battery, but the battery is clearly marked as 300 mAh.

Update: Ars got a response from Motorola: "For Moto 360 we only had room for one figure and choose to list the minimal capacity of the battery. We see how this can be confusing and we will look into ways to add the typical capacity as well in the future."
