It's a milliamp-hour. The processor draws about 220uA [1] so you have about 818 hours (=34 days) of CPU time, but you need to take display current out of that

It's a milliamp-hour. The processor draws about 220uA [1] so you have about 818 hours (=34 days) of CPU time, but you need to take display current out of that budget too, and an easy source for that probably exists, but I can't find easily.
