That ' s less of a concern from the battery . Isolating the battery also helps in hot environments to a degree as well , as high ambient temperatures will not heat the battery as quickly . The battery really only generates any significant heat when charging , so in normal operation , you don ' t need the case acting as a heat sink for the battery . It ' s already doing that for the SoC , which generates heat anytime it ' s in use , charging or not , so you don ' t want to pass that heat to the battery too . <| sep |> Then why do he needs to sleep ? <| sep |> The old sailor uniforms .
