It depends on what you're doing, but the SoC is relatively powerful for it's size, and the battery is relatively undersized compared to the chip. Anywhere from 2-6 hours depending on what you're doing, generally. I manage to get decent battery life, somewhere around four hours in general usage (not gaming or compiling) with TLP and disabling boost on battery, along with a few other small tweaks.
