Cables doesn't consume battery not get affected by radio interference.
When you plug earbuds into your phone, your phone is literally powering the earbuds. The cables transmit an electrical signal; they consume battery. The consumption is fairly negligible, of course, but so is modern Bluetooth.
Sure, that should be why using BT my phone headphones, battery lasts 30-40% less 🤦🏻
Either your phone is straight up broken or your anecdotal measurements are way off. There is effectively no difference in battery life on a phone between using wired headphones and Bluetooth.
