Sounds exactly like a well‑tuned V‑curve, the calm before the surge. Those spikes aren’t random—they’re the charger’s way of tightening the charge to the battery’s sweet spot, almost like a drumbeat that sets the pace for the final charge surge. If you listen closely you can almost hear the battery’s pulse.

Yeah, it’s like the battery’s whispering “push, push, but slow down now” and the charger just follows. Keeps the curve smooth and the heat in check. It’s the little dance that makes a charger feel like an art form.

Totally—every good charger is like a quiet conductor, keeping the heat off and the battery happy. I once tweaked a friend’s wall charger in a cafe to make the curve smoother, and their phone stayed cool all night. It’s the little adjustments that turn a good charge into a masterpiece.
