Apple

So i purchased an iphone 13 a year ago and it has been super laggy since the last few months!
Scrolling through app drawer, search bar not loading, app crashes, camera app laggy especially in low light when it has to adjust timer, reddit scrolls, and even while switching tabs in safari!
Also, how can i forget, the most irritating experience of typing! oh god it is irritatingly laggy af!

My current storate is 120gb full out of 128 (even tried cleaning it, was lagging equally at some 50gb full as well), battery health is 87%. Please suggest me something, i am already loosing iphone vs pixel battle with my friends, the only thing i could stand for apart from video, is user experience but even it is lagging.
