you will be blown away I think.
I went from an s21fe to a s23+ and just the battery difference blew me away. I love the s23+, but liked the s21fe until I got the s23+ if that makes sense.
I had to run at the slower refresh rate on the s21 to even get close to the battery life I get out of the s23+. I run the S23+ with the 85% charge and it curb stomps any phone I’ve ever had. Even my one plus 6T. I for sure will be keeping the s23+ until it dies. The entire time I had the s21fe I knew I would be upgrading sooner rather than later. I was trying to hold out until the S24 came out but then samsung gave me 300 dollars trade in for the s21fe while having the s23+ on sale. I ended up getting the S23+ for 530 bucks shipped after trading in the s21.
Did I need a new phone? Nope
Am I glad I got the S23+? Yes
S23+ Damn good phone
