I have aspire a315-55g notebook, when I tried to install ubuntu 20.04 I had a lot of battery issues, battery don't last for 2 hours however it was last for almost 4-5 hours on windows 10. What may be the problem ? 
hint * I tried many solutions from the internet but it didn't work.

    this is because linux has poor support on switchable graphic. in your case, discrete video card is always on.

    I tried to turn off my Nvidia mx230 graphics card and still the same issue. After some research I found that the problem is because the CPU, it works 100% all time. But I can't find any reliable solution to this problem.

    if the cpu is on 100%, what is the process taking up the resources?  (System monitor)
