Yes, it took me some hours to adjust the LED strip to minimize the effect, but the LED artifacts s are still faintly recognizable in the bottom 5mm of the screen if I'm in a dark room and the screen is mainly white in this area. However, I usually use this laptop as my daily coding workhorse within a terminal with a dark background, where the effect is not present.

Regarding the battery, I use this one: https://www.laptopbatteryexpress.com/Lenovo-long-life-ThinkP...

Battery life is around 7-8 hours when I am coding with 100% screen brightness, using a basically vanilla Ubuntu 16.04. It was close to 9 hours when the battery was new.
