5 months is too short a time frame to see benefit from battery management. Upgrading phones every 1-2 years also may not see a significant benefit (except perhaps the
12 series). 3+ yrs is where the batt mgt really pulls away, and I’m personally a ~6yr guy (‘08 iP3, ‘13 iP5, ‘19 iPXR). My 2.5yo XR is 96% health and can still probably hit
15-16hr Apple SOT spec, although I only have time/patience for ~half that per day.
A $69/1hr battery swap is another option of course, but a smartplug/shortcut-optimization is a fraction that cost, time, effort, and half the end-of-life ‘batt-sucks’ experience (for me, YMMV and all).
