About this wifi chip (AX210/AX211/AX411), one last issue I have with it is when I go to batteries, it burns a lot of power: > The battery reports a discharge rate of 36.8 W > The power consumed was 772 J > The estimated remaining time is 1 hours, 56 minutes > > Summary: 1657.3 wakeups/second, 0.0 GPU ops/seconds, 0.0 VFS ops/sec and 121.5% CPU use > > Power est.
