I use Arch/sxmo mainly, also Arch/phosh (See setup details here.)
In suspend mode get way more than 24 hours - would need to check Megi's pages but think he calculated 36 or so theoretically. I much prefer sxmo in general, but specifically to suspend you KNOW it is suspended when the LED stops flashing!
Active use (browsing, email, telegram, some mpv) maybe 3-4 hours

Note the default cpu governor in Danct12 Arch images is conservative: I change my default to schedutil as don't see the point of permanently doping my cpu. In theory bad for battery but what I get is still fine.
Hoping that I can improve my active use life if I can get Megi's DRAM scaling working.
