Those new thermal‑throttling tricks are a mixed bag. On paper, a smart duty cycle that steps back once the charger hits a certain temperature sounds great for keeping the battery in a safe zone. In practice it’s a dance between protection and performance. When the spec kicks in early, you’re losing peak power before the cell can even heat up, which means longer charge times and a less efficient use of the cable’s capabilities. But if the throttling starts too late, the battery sits at high temps, and that’s a recipe for accelerated calendar aging and a drop in cycle life. Manufacturers that market “zero‑degradation” throttling usually set a conservative threshold. They’re protecting the battery but also masking the fact that the charger can’t push the full spec. I’ve seen some folks tweak their chargers to push a little further, but that opens a can of worms: you get the immediate benefit of faster charging, but you’re also running the cells into a hotter, less stable regime. Over the long haul, that can shave off a percent or two of capacity per year more than the spec’s baseline. Bottom line: the thermal‑throttling tricks are a useful safety net, but they’re not a silver bullet for battery longevity. If you’re in it for the long haul, it’s better to stay on the spec’s recommended limits or use a charger that offers a stable, lower‑temperature charging profile. That way you keep the battery happy and the charging curve predictable.
