That may be the case with your already worn out battery. The fast
charger with 20 Watt recharges my Pixel from 20% to 80% in under 30 minutes.

But it can help you to keep a future phones or Li-batteries in general
at a healthy level for a much longer period of time. Most devices have
firmwares now, that allow to preprogram the charging cycles (Pixels with
Android 15 and up and iPhones 15 and up).

My iPhone 14 claims to be at a SOH of 97% after 2 3/4 years of daily
usage. The performance of my Pixel 7 is also still top notch after 3 years.
