@odh , while i feel diagnosing PP problems are off-topic here, i can report having good results using suspend with Mobian. PP reliably wakes up on power button and calls but not on WLAN, yet. Battery life with light use is greater than one and a half day, which is acceptable for me. I expect likely times for the L5 once suspend becomes available for it, and indeed, these were (very preliminarily) confirmed:

Status of Suspend for Librem 5

SMS, Calls, Vol + - , power button, all this wake up the L5. I used the terminal to put the L5 on Suspend, but also there is a button on posh to enable. @weirdnerd : I not tested yet the battery, but i believe it is 2% on suspended, compared to 8% per hours on inactive mode.
