For me also the same experience! Before the OneUI5 update, a single charge used to last more than a day( or almost 6 hours SOT) depending upon the usage. But now, it's the worst. Even if you charge 100% in the morning you have to connect the charger at around 7 PM(with just 20% battery remaining). SOT is just a bit over 4 hours. As per some other threads, I have cleared the Chache partition but no significant improvements. Any leads would be appreciated!
