Al Dente didn‘t really work for me. I used it constantly for 1.5-2 years (capped at 60-80) and my battery still went to 88% of design capacity. My iPhone‘s battery on the other hand has been tortured for three years (always charging 100%, fast charging, getting very hot in the sun) and is still at 85%.

I feel like the batteries nowadays are just made to last 2-3 years to get to 85-80% capacity no matter how you treat them
