Core charges in two ways: power connector that attaches to the 3.5mm headphone jack, or via the attachable plate that allows wireless charging. Thus, you'll probably be able to attach a small external battery pack to make it run all day. That said, I'm more interested in figuring out how to get offline speech recognition running on Core with something like PocketSphinx and only relying on the 3g connection when needed. All this has got me thinking about what the smallest Android boards/devices out there are and how I could get a Raspberry Pi Zero connected to a cellular network. Need to do more research on this.
