Safari - Using Significant Energy

Even when only one tab is opened on Safari browser, Safari shows as “Using Significant Energy”. Is this something to be concerned about? Not sure if this is normal?

Using Catalina 10.15.6 on a brand new MacBook Pro 13”.

Any advice would be appreciated.

In truth there is little you can do to fix this as its often the web page you’re viewing is forcing your system to run code which is looping and/or has a memory leak.

You still want to make sure you have a good antivirus, malware and spyware apps to reduce your risk of getting infected. Also make sure you don’t have any Safari plug-ins which is causing issues.

Any particular Malware and Spyware apps you would recommend @danj ? For antivirus, I use Bit Defender. Any thoughts?

When you state that a web page might be forcing the system to run looping code etc. - would just the Google home page also do this for example? I have no extensions and plug-ins installed at the moment. I notice that even if I simply have the google homepage open on a single Safari tab, it "uses significant energy". What could I do to resolve a memory leak, if that is indeed the problem?

MalwareBites is a good tool to have!

What happens if you just open a empty widow or Apples web site?

As far as looking for memory leaks you have Activity Monitor for that.

@danj Thanks will install MalwareBites. I think BitDefender Antivirus for Mac has been slowing down my system a little - or perhaps I am imagining things. Not sure.

Been noticing some strange behaviour with Safari:

Upon a reboot of the MacBook and when opening an empty window - No apps using significant energy.

When opening www.apple.com - Safari using significant energy.

When opening a blank window after a reboot and a minute or two of browsing - Safari using significant energy.

Posting some screenshots of the Activity Monitor.

@sz1809 - Well you have something lurking inside of Safari !!

Did you add any plug-ins? You do need to run MalwareBites to see if there is something in Safari.

You could also try creating a new user account to see if its reacting the same way.

@danj I ran a scan with Malwarebytes, no threats and PUPs detected. On Safari, I when I noticed this issue, no plugins and extensions were installed. The "Using significant Energy" issue started showing up from the time I used the MacBook when it was brand new last week. I recently installed Bitdefender AV so it has now installed three extensions in Safari which I have not enabled, but even when there were no extensions installed, I noticed this behaviour. I will crate a new user account and see if Safari is behaving the same way. Will update.
