Hello guys.I have been here 3 months ago and did not solve battery drain problem.So i sent my laptop to acer services.I live in Turkiye,but i bought laptop in Dubai.I had international warranty,but nobody accepted my laptop in Turkiye,so I had to send my laptop to dubai,where i bought it.After 3 months,i finally got it and problem still remained.In acer services they said that problem was with battery,so they changed the battery,but I knew problem wasnt the battery.So I tried undervolting my GPU and CPU and it SOLVED the problem.So guys if you have this problem,download MSI afterburner and find a video on the internet how to undervolt on THIS LAPTOP AND THIS GPU.AND BE CAREFUL WITH IT ,PLEASE!!!You cant undervolt cpu on this laptop,so i downloaded Intel Extreme Tuning Utility and turned off Turbo Boost Mode.After 6 months,I solved this problem for me and I decided to write this here if it helps you
