There's been some hubbub in the past few hours over the Moto 360 not having the size battery it claimed — iFixit's teardown showed 300 mAh versus 320 mAh claimed on the spec sheet. Perhaps not a huge difference, but every little bit of juice counts in a smartwatch, particularly since the 360 has proven to be a little finicky.
Motorola has responded to inquiries about the matter, and they gave a statement to ComputerWorld.
Here's the deal:
The typical battery capacity for Moto 360 is 320 mAh and the minimum is 300 mAh. In the mobile industry, sometimes both the minimum and typical capacity is listed on the battery, with the typical capacity quoted as the official battery size. Both figures are included on the batteries of our Moto X, Moto E and Moto G devices. In the case of smaller devices, we aren't always able to list both figures. 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.
So, it's not that the batteries are smaller than Motorola advertised, it's that Motorola decided to put the lower of the two numbers on the component so as to avoid people screaming and calling them liars if that particular battery wasn't actually the full 320mAh it says on the side. Batteries fluctuate in actual usable charging capacity the way hard drives and flash drives do.
So, put the pitchforks down, and let's all get back to seeing if that battery — which is what Moto advertised after all — is actually enough for most users wrists, because the multitude of early complaints about battery should be by and large ignored. Devices get played with more and battery life needs breaking in, just like every other part of a device.
