A:Answer The stated 15 hour battery life sounds like a stretch if you ask me cuz that would imply only using 5 Wattd (battery size = 75 Wh divided by 15 hours = 5 W). The fine print says that test was done with a lower spec CPU than this one, playing a 1080p video at half screen brightnesd. Translating to this model, only one Efficiency core could be running to get as low as 5 Watts. But a light to medium-light load might be 2-6 Efficiency cores, so yeah, under those circumstances I could easy see a 12 to 10 hour battery life. Any AAA multithreaded game, though, might get you down to a 2-4 hour battery life - but with the efficient ARC-based iGPU built-in graphics, that probably lets you hame on battery longer than with an expensive graphics card.
