That's the only problem I've seen with my Nvidia shield K1, the battery goes down pretty fast! Or at least mine does, I've paid ALOT to get the Nvidia shield k1 charger which is 2.5 amp charge but it doesn't charge fast like you'd think it would and when it is charged and I'm flying the battery goes down to needing to be charged with the booster pack I carry for it! Does any or everyone else have the same issue??? Or just mine?? Because I've been considering calling Nvidia to ask if this was normal or not,
Mine goes down fast also!
