[unboggling]

This battery discussion applies to all devices (phones, tablets, computers) that use lithium-based batteries. I've never troubled to do this before, but I'll plan to start calibrating the battery (fully drain, leave off a half hour, then fully charge) for my notebooks and devices about once a month. (Edit: Specifically, devices that are plugged into power most of the time, the others should be okay without regular calibrating.)

I haven't checked lately, but probably the iPhone in my car has a permanently dead battery because of leaving it there baking in the heat, not using it for months. Sigh. Guess I'll have to remember to carry the phone around rather than leave it in the car.

Edit: brain implants will be a lot more convenient—if they don't need messing with the battery...
