19 hours battery life
My Lenovo Yoga C940 has a big advert on the front page of the website advertising 18 hours battery life .....
At best it gets 3-1/2 .... and it even runs down with the laptop completely switched off so if you've not used it in a week you have to charge it again.
Large pinch of salt and all that.
Oh, and no thunderbolt 3. Really ...
