    Hi

    I have a 2015 MBP 15" and the 'energy impact' of Safari is relatively high around 30. Sometimes it spikes even further to 90. All I'm doing is browsing a few pages and watching YT.

    Tried SMC and NVRAM reset, but no avail.

    Any ideas?

    You can expand the safari line in Activity Monitor and see energy impact per process / web page. That should give you an indication of what is going on. This is what my 15" shows with only MR open:

    So yeah, I have no idea why it's taking so much or if that's normal (new to Mac)

    Safari hovers around 26 - 30 on my 13" tMBP. It was relatively the same on my 2015 15" MBP as well. Chrome is just as bad, or worse. I think this is just the cost of doing business with browsers these days.

    Energy impact is relative. So doing the same task in Safari with nothing open should give a higher figure than with out her CPU intensive tasks going on. The number itself in isolation is not hugely relevant.

    I'd advise trying another browser and compare the energy usage.

    I do know that Safari runs really poorly on my MacBook Pro while Chrome runs really well, especially when it comes to YouTube video playback.
