I'm experiencing lower than expected battery life on my 2015 Macbook Pro. I believe that part of the problem is that the High Performance GPU is being activated when not needed by some tab in Safari: Activity Monitor Energy Pane

This is NOT a CPU related problem, as the CPU tab in Activity Monitor shows little activity: Activity Monitor CPU pane

How can I tell which tab is requiring the high-performance GPU?


After closing all tabs, Safari is still requiring the high-performance GPU.

  • Close each tab in turn, watch for changes.

  • @SolarMike yes, that is an option, but I use the tabs to remind me of what I need to go back and review. I'd prefer to not have to close them.

  • So bookmark them...

  • Surely there must be a more definitive way.

  • There may be, but how long are you prepared to suffer / wait or do you want to find out sooner?
