MBP 15" 2017 battery life issue.

[xlegion]

Hi, lately i feel my battery life going down quickly. Morning today i leave my house with 100%, after 2-3hours working on AI and AE without WIFI connect, laptop starting heat up more than usual about 65C. and my battery going down to 25%. It never happens before :/. Usually i can work like 4-5hours. Is it acceptable reason for RMA?. I think the problem started after the latest HSierra update.
BTW: i use Bluetooth mouse and keyboard aswell, is could burst battery life too?
Thanks for advice

You need to figure out what is causing the processor or GPU to work harder. Harder work means more cycles which takes more power. Use Activity monitor and check the CPU usage.
