iPhone 13 mini - Battery short-life even with 100% health?

I’ve been noticing that my iPhone 13 Mini rarely endures a full day even being less than 6 months old and with 100% battery health.

also, i only do light tasks as social media browsing, web surfing and rarely music or video streaming. I do not play any games on mobile.

here’s a screenshot. 2h of screentime and less than 30% of battery left.

many reviews in the internet mentions that the battery for this model should endure 5h of screentime…anu thoughts?
