Hello - I have had my Surface 2 for a couple of weeks and overall am very impressed. I have one issue, this being poor battery life, typically draining by 20% per hour which seems poor to me I have the screen turned down to around 30%, Bluetooth turned off and close all of the apps after using them. I have a 32gb micro sd card within with many photos etc - could this be an issue? Other than this I am impressed but find the current battery life very limiting when compared to my iPad. Was there a recent update that seems to have worsened the battery life? This is my second unit as I returned the original due to a 'bruised' area on the screen, that unit had similar battery life also so it seems the norm for this unit? Any help would be appreciated.
