What’s wrong with the 🔋?

I’ve been feeling that the iPhone 16 pro doesn’t have the capacity that’s designed for. I’ve been having some battery issues, only have 5h screen time max without using it that much. Did a reset and also a battery rebalance (0-100%) and nothing. I used the phone this morning for like 10 min max and I have 6% off. I have the iPhone since it came out. I don’t feel like it’s still indexing.
