Among current phones, the Mudita Kompakt (3300 mAh + E-ink) leads for active use, while budget flips like the BLU Tank Flip lead for pure standby.
›Why do dumbphones last so long on a charge?
Tiny low-power screens, no background apps, and radios that idle most of the day. There is simply very little drawing power.
