Windows 10: battery draining fast.

Hi,

My question is that i bought new laptop acer brand , I replaced it because of battery issue becuse company claimed 12 hrs battery backup but it wasn't giving 6 hrs . when i replaced it in new one i faced same problem. i did some setting on windows and then battery was fine but again same problem then again i have to disabled some services after that for few days it was fine then again . In short please help me figure out why my laptop on windows 10 home single language version 2004 which is pre-installed consuming alot battery it is clearly windows fault . I tried everything disbled services which consuming more power and cpu usage i also tried turning off unnecessary background apps nothing works for long time .i want to use windows properly and also need battery backup. i only use brower google chrome and microsoft edge and one or to applications . please reply fast im fed up from this behaviour.
