> dead battery? mac wont start for 15 min on connecting power
replyHaving just received an M4 in the mail with a completely flat battery, I can confirm this is nearer 10 seconds on Apple silicon (you are correct it used to be this way on Intel Macs)
Having an M1 and an M2, no it isn't. Takes at least 5 minutes on the 65W charger to get bootable from a full drain. Maybe something changed with the newer models but it isn't a benefit across all Apple Silicon.
replyHave never tried the 65W charger, but have had no issues booting from fully discharged with the 96W brick
