How Power Usage & Power Usage Trend Work in Task Manager?
If you see that the power used is high in power usage tab don’t worry. Just have a look into trend option as well, if it shows low, then you must be okay and need not do anything. The reason is, for the time being the app, it might use high power but the overall trend could be low. If you get the overall trend power usage high, then you certainly need to close that process if it’s not important.
Note: While closing any particular process or task, make sure that there isn’t any “Windows” word included in the description. If it’s a process or task related to Windows, the system might end up being unstable if you stop, disable or end the task.
