Battery drains fast and gets too hot (even after reset)

[FeleK]

After few weeks my s7 edge began to draw faster battery and get hot. I deleted and resetted the phone. I turned power save mode on. Nfc of. Wifi off when screen closed etc... i even didnt install much apps .still i get too much battery drain. Screen on time is mostly around 3 hours or less. It was not like this and I don't know what to do. Warranty is probably not going to accept it. Because they just don't want to change it. I got pictures of phone heating and gsam battety drain.
