What's the battery life of the new iPad 4G with LTE disabled/enabled? I saw a video about the new iPad and it showed that you could disable LTE.

Apple had to increase the battery capacity in the new iPac because upgrades like LTE and the new display draw significantly more power.

  To put that in context, an iPad 2 with with this new battery, if such
  a device existed, would probably last close to 17 hours on Wi-Fi.
