From what I remember from the initial reviews - the S22+ was the lemon of the family - you were better either just sticking to the standard S22 or going the whole hog and taking the Ultra as the battery life on the S22+ was pretty poor. Whether there's been any improvements since then I'm not sure.
I always liked the idea of the Sony Xperia phones but always felt disappointed both with their crazy soft launch/real launch schedule differences and the general support afterwards hasn't been great.
Mainly battery life was the main reason yes
If you're using the phone for photography then I really would recommend saving a bit longer for the S22 Ultra - the cameras on it as many will tell you in the S22 thread are awesome!
