Just anecdotal; I bought the previous gen x360 because reviews said it had good battery life. I find it a terrible machine; I get maybe 2 hours of battery out of it since I bought it; I went back many times and they say it is my usage (Chrome and Visual Studio) but other laptops do not have the same troubles. Also, it seems to have incredibly inefficient standby battery usage; again HP says it is normal ‘for my usage’. I would never buy again.
