Notes on aspects of the Glass battery ...

When using the video camera for longer than about a minute or two the touchpad side of Glass becomes fairly warm. Not the behind the ear counterweight. Likewise when charging the same area becomes hot, while the behind the ear portion remains at room temperature as far as I know. 

I've heard mixed things about where the battery is. Some articles describe the behind the ear as a counterweight, others say it's the battery. Same with people I've talked to. So where is the Glass battery exactly?

I'm not about to hack my Glass so don't ask! But my belief is that it paradoxically is in the main body, not behind the ear. Otherwise it makes no sense that the body gets hot while the battery remains cool, unless there is some battery technology unknown to me that does not generate heat while charging and discharging. 

But then, if true, why in the heck would the Glass team NOT use that counterweight as a battery? Mysteries abound ...

On power usage and battery; without hitting Glass all day for demos, videos and pictures (as I've been doing) it will easily last a day. And if not then you can charge on-the-go with a right angle plus. However ... in the attached video I discuss some issues with the beautiful but problematic Glass USB cable. I'll post a picture of one I bought from Amazon that works better and why. 

On charging time it truly is quick - I haven't measured it but about an hour or so. Much quicker than your cell phone. 

Finally, the only question I have about the longevity of the device is the battery, will we be able to get it replaced? That will seem to become important down the road.
