I don't trust their battery run-times. I was looking for a laptop and finally settled down for a Lenovo Thinkpad 13.
Thinkpad's battery is 42 Wh with a wifi surfing run-time of almost 7 hours [0], although it being sold as a 11 hours run-time. It hasn't a dedicated graphics chip.
Xiaomi's battery is 40 Wh and it sports dedicated graphics. Macbook Air's battery is 58 Wh and it has integrated graphics, lasting around 10 hours [1].
Assuming a similar consumption, Xiaomi's would last less than 7 hours for surfing. But it has dedicated graphics (NVidia 940M) with a consumption (30W) that doubles integrated options (Intel HD in Lenovo and Apple laptops). So, probably it will last 5 or 6 hours of just wifi surfing, even less.

- rsynnott 10y agoThe battery claim may be for the smaller model, which uses a Core M (similar to the new Macbook). That wouldn't be comparable to the Thinkpad or Macbook Air at all.
- im_dario 10y ago9 hours is for the 13.3 inches model. The smaller model is claimed to last 11 hours.
- nojderle 10y agoI don't know anything about electrical engineering, but could it be possible to optimise that ?
- pcr0 10y agoIt uses Windows though, which should support Optimus and allow it to switch to integrated graphics.
- fulafel 10y agoLaptops with discrete GPUs tend to have an integrated GPU as well, and keep the discrete GPU powered off most of the time. The 30W you quoted is the maximum power consumption for the discrete GPU, when it is active and running at full tilt.
- naspinski 10y agoMy Razerblade can run for 6-8 hours on battery and it has dedicated graphics. When I am actually running a game, that approaches more around 1 hour.
