Every modern android phone with good power bank knows how to negotiate exact power level, do bypass, start an stop at specific points etc.
Though it is hard to find a battery that is both magnetic and supports android-specific power negotiation protocols.
I have magnetic case on a S22 Ultra and magnetic rings attached to samsung original wireless batteries, as well as Anker magnetic battery/stand combo and they work perfectly with no wasted power.
Previously I tried orico, baseus, belkin, ugreen and a few local rebrands of chinese batteries and chargers and none worked properly. Some keep blasting after phone is charged, some flipflop between zero and full power every second causing unnecessary heat, some can't automatically turn on after turning off at full charge, or some combinations of the above issues.
