Comment on Is Fast Charging Killing the Battery? A 2-Year Test on 40 Phones

I always find the same study referenced, which was good science but also almost 30 years old. I wonder if this is still true for modern batteries?

Correct me if I’m wrong, but as far as I know there haven’t been significant changes in Li-Ion and LiPo batteries aside from extra density - which would only increase the effect. But it seems like solid-state batteries are starting to hit the real world now

  I bet thats wrong, but I know ….
  
  There’ve been usage changes
  
  iPhone has “Optimized Charging” where it predicts usage and tries to keep about 80% charge until it expects you to use it
  
  iPhone has “Adaptive Performance “. Maybe not charging but tries to gradually ramp to “low power mode” to be gentler on the battery
  
  all phones likely have refined charging curves to match battery technology
