But i was on vacation this weekend and charged phone through my Mac and it lasts at least 36h after charging. I don’t know what should i do now. Seems like they make a phone what only you can charge from you pc for a longer use.
The phone doesn't know where the power is coming from. Electricity is electricity. It sounds more like there was a problem with the adapter you've been using. It's possible you were using one that didn't pull enough power or was defective. Newer iPhones require more powerful adapters.
I got my iPhone 15 Pro on launch day, and I don't think I've ever charged it from my computer. This is the adapter I've been using:
Anker 20 Watt
Note that it is a 20 Watt adapter.
