Dude you literally charged twice in between. Whatever you are showing is not the true battery backup. Fully charge it to 100%, use it until battery is very low then see what screen time you get, that is battery life. If you charge it upto 85-90% the charge cycle does not change and assumes that it is the same cycle. Using this trick I can even show 10 day battery life with 8 day SOT on my S22+.
