MacBook Pro 2021 M1 Max: Power Consumption – Low And High Power Mode

Even the first M1 notebooks could claim to be true battery life wonders, but Apple did not want to abandon these ideals for the much more powerful models with M1 Pro and M1 Max either. According to practical experiences so far, the MacBook Pro 14" and MacBook Pro 16" actually last much longer without a power plug than it was the case with their direct Intel predecessors. Apple itself speaks of up to 14 hours of web surfing in the case of the 16" model. This value can definitely be achieved in everyday use, although it naturally depends heavily on the respective field of use. Embedded video content via YouTube is naturally more energy-intensive than websites without such content.

Accurately measured: Power consumption MacBook Pro M1 Max.
A new test cycle now looks at how many watts the MacBook Pro with M1 Max requires under various conditions - measuring what the charger pulls. The built-in battery has a capacity of 100 Wh, so power consumption and battery lif can be put into relation well. Some interesting key figures of the test series, the display was always set to 50 percent brightness:

  • YouTube videos: 17 watts
  • Normal website browsing: 10 watts
  • Final Cut Pro, normal operation: 18 watts (peaks up to 60 watts)
  • Full load (benchmark tests): up to 110 watts
  • Full load in High Power Mode: Also up to 110 watts
  • Full load in low power mode: Up to 76 watts



Some findings
Since no differences between normal and high power mode could be seen, the MacBook Pro apparently switches directly to the maximum level under full load. It can also be clearly seen that the power consumption is significantly reduced in Low Power Mode, as the wattmeter's reading never rose to more than 76 watts.

The value mentioned regarding Final Cut concerns usual workflows when editing a project, but not rendering a video file. As the tester states, one battery charge is enough for about six hours in this scenario. As soon as it comes to export, on the other hand, you are more likely to find yourself at the test's power requirement under full load.
