Default Extremely Fast battery drain. . N9005

Hi.

Wondering if anyone had seen this before on there note 3. My battery was 100% when I woke up this morning. Within about 2 hours it drained down to about 6%.

When checking battery stats there is a system app that looks like it was the culprit.

My phone was red hot for ages before I noticed it. .

It looks like it's the camera or something to do with the camera.

See screenshot. Can anyone advise add to exactly what it is?
