I had a pristine s8 as well. I bought a new battery. Still slow to charge and fast to run dry. Within months the s23 came out and I bought the s23+. I love it for not going dead before the end of my day. Now my s8 sits on my bedside table with plug in ear phones so I can listen to podcasts at night. My s23+ is my daytime full function phone and internet connection. Yes it was worth upgrading!
