Screen flicker with Dell Inspiron 15 7000

Hello,

I bought a new Dell Inspiron 15 7000 core i7 with touch display about a week ago. I've noticed that on occasion, especially when running on battery power, the screen flickers slightly.

I've tried to ignore this issue, however it is starting to irritate me and I've looked all over the internet for a solution. 

If anyone has experienced this issue or knows how to fix it, please help!

Thanks!
