Ever since Microsoft added "modern standby" it's not a problem anymore. Chips became power-efficient enough that we can just "fake sleep" now, which means disabling all but one core and downclocking it to the lowest possible frequency. My AMD laptop was 400mhz, draining about 15% per day.

Say what you will about Microsoft, but sometimes a strong leader can make good things happen (TPM2 and modern standby)
