I haven't seen any calculations for battery life, and I'm not sure we have the data to do them. You could start adding things up from datasheet values, but that may not be very accurate. I suspect the main limitation will be the modem as it doesn't seem like Quectel have optimised their software for battery operation - but we could just be missing some power saving configuration options.
You can't suspend any phone when streaming a podcast because the CPU is required for streaming. At best you can shut down the subsystems that aren't in active use - depending on the CPU this may include shutting down some cores, clocking the used core down and/or shunting processes to a slower, lower power core. It may outwardly look suspended, but it isn't. Android usually shuts down wifi in actual suspend too - which breaks incoming SIP calls. When there was an option to keep it powered it had a large effect on battery life.
'All day battery life' always confuses me because it's so dependent on how you use the phone, and how much transmit power is needed to reach the phone mast.
