My phone is draining its battery far too quick, I've had my phone a little over a year it heats up whilst charging, the battery power doesn't last at all, I've ran a diagnostics test and everything and nothing
I would first go to support in the samsung members and their is a function call diagnosistics would uses that check the battery to see if you need a new back secondly check to see if their are any apps that are driving down your phones battery 🔋 and also check to see if your have any updates too. Hope this will help
