I’m a battery/efficiency hobbyist - if you do it right with an automated custom charge optimization (smartplug + shortcut, or chargie usb dongle), there’s no effort/cost/hassle after initial set-up, and batts should last longer than Apple will support the OS. The built-in ‘optimizations’ are ok, but too dumbed-down to capture the best lowing hanging fruit (eg, idling/resting overnight at low SoC). However, the 80% limiter combined with a dumb light timer, or a morning charge routine, recaptures most of that.

My XR seems to be doing fine after 4yrs and I still use my 11/12yo iPhone5/iPad2 (w/ 5-6 SOT on original batts).

Curious what the purpose is? So it won’t ‘overcharge’; you want to limit the peak charge for batt care; or you want to minimize the time you’re waiting around for it hit 100%?

Without specific battery care, ~4yrs is beyond the batts useful life - just replace it.

My XR is ~1/2yr older with very similar usage pattern (8-9hrs Covid, 5-6now) and is 87% BH and ~50% cycling gets me through the day. But I’m a batt/efficiency hobbyist, and wait til ~v.3 on new iOS rollouts.

Do the 100-0-100 battery recalibration - it fixed my XR when it started shutting down at ~15%.

Don’t think raise to wake matters much unless you also turn-off the Health App (step counter) - either one turned on means the accelerometer runs 24/7 IMHO. I use a shortcut to toggle between wifi-calling/cellular when I’m home/out, so only 1 antenna runs at a time. GPS is huge as Apple uses as many phones as possible as crowdsource beacons. FWIW, I’m a battery/efficiency hobbyist that gets Apple’s ‘up to’ SOT spec for year.
