I recently received a MacBook Pro which I am doing a little troubleshooting about the length of battery life with and wanted to reset the SMC. Is the procedure the same as for MacBook Pro's with the T2 chip? (left) ctrl + opt + (right) shift - 7 seconds, then add pwr button 7 seconds and release. Also, I was told that there is no NVRAM on these Macs. Is that true?
Thanks in advance.
MacBook Pro 13″, macOS 11.0
Hello jeffmr4
Thank you for contacting Apple Community
You can’t reset the SMC, because the M1 Mac doesn’t have a System
Management Controller. You can’t manually reset the NVRAM / PRAM because
your Mac does this automatically, if needed, during every startup.
Best regards,
John

I am unclear how the 1 True Recovery (1TR), Recovery Mode is related...
Since the M1 has no SMC—
M1 Macs similar to a SMC reset by shutting down the computer and leaving it turned off for at least 30 seconds before turning it on again.
If your M1 computer has a problem with the hardware of the kind that can usually be fixed with 'the old SMC reset,' the only solution is to put the computer in DFU mode and reinstall firmware with Apple Configurator 2 from another Mac. DFU is Device Firmware Update, see Apple’s ref guide:
