> After several nights of losing all my free time after work only to wake up the next morning to a dead laptop battery, I treated myself to an m2 13” mbp.

LTT just did a video on something like this: https://www.youtube.com/watch?v=OHKKcd3sx2c

tl;dw: It may not be a OS problem, but rather a problem of which sleep states are supported by your firmware, which would explain why nothing you did helped. Possibly suspend never really worked and Ubuntu just got meaner on the battery. Getting a MBP is valid fix if you disable "Wake for network access" on it.
