For all of its UX problems, I must say I am very impressed with Small Childs battery life. The low power shutdown does tend to be very noisy though.

Yeah the low battery warning is extremely obnoxious and not dismissable at all. I don't know who thought this was a good decision!

What's even more crazy is that often when I attempt to silence the low battery warning by placing the Small Child in the charger, it often refuses to begin charging until the battery has been entirely depleted, so along with not being dismissable, even attempting to charge the Small Child does not stop the low battery warning consistently! I believe this is likely a bug, but I haven't yet been able to consistently replicate it to file a bug report despite experimenting with various charging and usage schedules.

Mine evidently felt in need of a recharge last night and used its optional fuel intake valve to ingest some of my espresso, finding it not 100% compatible with its system it ejected the espresso and made an error sound, after which it walked around the room, came back and went for the espresso again. Prevented second time by manual intervention.

I've found that, while the smaller model's battery life seems boundless, what really drives the appearance is their remarkable ability to recharge quickly. I can wipe out the battery of both of of the smaller models I'm currently in charge of and within 2 hours they have resumed normal levels of activity.
