According to a feature from the folks at GamePro
, Xbox 360 owners can expect more gaming bang for their battery-life buck. Multiple tests on the Xbox 360 wireless controller, SIXAXIS and Wii Remote were conducted to see which one would last the longest. Scraping the bottom of the battery-life barrel was the PlayStation 3 SIXAXIS which only held out for 18 hours and 41 minutes; mainly due to the lack of auto-off functionality. Second place went to the Nintendo Wii remote, doubling Sony's time at 36 hours and 43 minutes. Xbox 360's wireless remote topped the list at 56 hours and 56 minutes. While the article states that the Xbox 360 dashboard battery indicator isn't as accurate as the PS3 or Wii, a single-day charge and play session always lasted longer on Xbox 360. In case you were wondering, the irony that anything associated with the Xbox 360 won a reliability
test was lost on no one.
