After prolonged intensive use ...

I use the Lenovo Yoga 11s now been just over a month, and also intensely in university life.
My version is the i5 / 256GB SSD / 8GB Ram.

To be fair, I must say that I am satisfied on the whole, and enjoy working with the yoga 11s.
It moves thanks to the SSD really pleasantly fast high, is so quick to deploy and is from a performance point of really top.
Since most of the advantages and disadvantages, as well as technical facts found already in other reviews on sufficient mention, I would like to mention two small things that personally tarnish me the joy of my device repeatedly sustained.

1)
The battery life of 8 hours typical described I have not yet been successful in everyday life in the Fachhochschule. I surf every day with the device on the Internet and compose written documents and when the battery for about 6 hours operation / working life, by holding, then the maximum is about which I reach. The display brightness then also constant in the lower third and the power saving mode is always active.
The advertised 8 hours are I have not yet succeeded. Maybe they succeed when I turn the screen brightness to the lowest setting and the Wireless disable.
How is imagines that in the context of Lenovo Energy Management allegedly possible 13 hours operating time without power at Lenovo beyond me. I suspect that this notebook just simply does not remain really usable. But well I have never given up the illusion that value in the FH-daily reach.

2)
The second thing that really bothers me is the fact that relatively quickly caused ghosting on my display. This means that if I have eg the browser over 20 minutes open to surf, the address bar, which all the time is indeed shown on static at the top of burning into the screen and is after closing the browser still clearly on my desktop, or Also the Metro interface of Win8.1 to recognize. Stop anywhere where you have a slightly darker background. So it is also with the constantly displayed Windows bar at the bottom of the screen. When displayed for hours static images I could well understand but unfortunately this effect is relatively fast with me on.
After a company (notebook for a few minutes of) these ghost images disappear, but are just as quickly reproducibly

Of course I do not know whether the one described "problems" with other occur, I could only watch with me.
Otherwise, however, I come super clear with the yoga 11s and use it very much. When it comes to mobility and performance, it is really great.

It is worth mentioning briefly that I have not bought the 11s Yoga on Amazon. In addition, I have a Scandinavian design with a German language pack and QWERTY keyboard, but this is no problem for me, because I have very rarely look at the keyboard to write anyway.
