I have a bay trail asus T200 which is a similar, albeit low-end, device.
The problem for me, under Windows 8.1, has been getting the machine to enter a true low power sleep state. If the machine enters the true low power state than it can work like a tablet, and if you use it lightly (say an hour a night) you can get a week's worth of use without recharging.
Unfortunately if any of the hardware components doesn't go to the low power state, the device will likely be dead or close to it if you don't use it for a day. Microsoft has a utility which tells you which component is keeping device from powering down, but doesn't tell you what software is causing this behavior. Windows 10 is supposed to improve this, but you can't turn off windows update so you lose one way to fight the battery drain.
One way you can fight this, besides plugging it in every night, is powering it down when you are finished, which isn't as bad as it seems because the device boots cold in about 5 seconds.
