Galaxy s7 edge battery graph

Right thank you but I've never seen white spaces in between the bars. Just usually a graph descending based on my usage. Now I have white spaces. Plz help
 
Likes the empty space? If you power off the device during that period, it will show the empty space.
 
Do you have a screen capture you can post here? I don't think I've ever seen a white gap unless the phone was rebooted. Any chance your phone is spontaneously rebooting without you realizing it?
