From your first picture, your phone is not entering in sleep mode (100% of time awake). It happens to me as well when I play music through bluetooth speaker, even after stopping music and closing bluetooth (I can notice the phone overheating due to high CPU frequency).
ou can use the Wakelook detector app to find who is causing the issue. To me, it seems to be related with bluetooth (or perhaps my music player, Rocket Player). Once I manually kill the "Media" service, phone gets back to normal. My hope is getting that fixed in future versions, when they finally show up.
Good luck!
