Everything perfect, just battery life underground

I have the version with the NVIDIA Geforce 2GB, 4GB RAM.
The unit is super fast, great fabrication, super display (reflects only slightly higher), great sound of boxes, illuminated keyboard.
The weight is right, sits comfortably in the hand and on the lap.
I am a student and have bought the Lenovo for the university especially for editing PDFs and Word documents.
I have emphasis on a good processor and a good graphics card, because the laptop is to keep for several years and is not completely slow. At the same time I was still important that the battery gets me through the day. According to manufacturer the battery should last for up to 7hrs.
With 6 hours I could have lived, but I have to say use after 4 days that I, no matter how hard I try to save energy, do not get over 4 hours of battery life - A very bad for me result that the use of laptops in the University not only difficult, but actually does not make possible. For this and only for this reason, the unit will be returned.

Conclusion: For those who do not rely on a long battery life, the Lenovo Flex 2-14 NVIDIA GEFORCE 2GB is definitely the first choice. Price / performance voices to the above point defect. For students like me, who sometimes have to sit on the Laptop 6 hours without outlet nearby, this device should not be an option. Who does not want to ascend to the next higher price class, which actually remain only the Chromebooks. All other laptops with 13-14 inches have either other very thick quirks, are priceless or get only average reviews.
