> but, well, compare battery life on an ARM Mac to a related x86 Mac; it is night and day. If I turn the screen all the way down so nothing can be seen, I can peg the processor constantly at 100% of my Intel Mac and still get 10 hours of battery life. The only caveat is that it's a 2010 Core 2 Duo, and what it does in 10 hours an M1 can probably do in 10 minutes.
