The standby power consumption of m4 except the cpu part is much higher than that of m3. How much is yours?

by Poster May 9, 2025 24

I recently bought the m4 max and found that compared with the m3 pro, in standby mode (when the cpu + gpu power consumption is within 1w), the total power consumption in normal mode is 8-9w, while the m3 pro is only 5w. When the power saving mode is turned on, the total power consumption of m4 max is 7-8w, and that of m3 pro can reach 3-4w. I know that the screen will account for part of the power consumption, but it seems that the rest of the m4 max still accounts for a lot of power consumption, including the total power consumption when the screen is not lit when the plug-in cover is closed. Is the rest memory or something? Can't mine leak electricity? cpu + gpu power consumption can be seen with sudo powermetrics or macmon The total power consumption can be viewed with macmon or aldente etc Here is the macmon screenshot https://i.imgur.com/cnump3Y.png

@ Anonymous3182 For example, this review [[Ozawa] 14-inch MacBook Pro review: Pro should look like Pro] [Accurately airborne to 17:34] https://www.bilibili.com/video/BV11v411u7Ch/?

@ Anonymous3182 The machine in this review is the m1 max 64G version, mentioned at the beginning

@ Anonymous6288 # 21 Okay, after looking at it, it's basically 0.5 w-1w, okay

The CPU part is more power-efficient, and the extra power consumption comes from the new high-frequency memory
