In my case i described what i did during that time usage. A video footage is not possible...Those 8 hours could be 8 hours of listening to music, which wouldn't be impressive.
Which is why posting those screenshots is utterly useless.
Wow that's bad. BUT seeing how you have WiFi AND Bluetooth on, i can understand the battery drain especially if you've been using it continuously.
