Cell phone gets extremely hot quickly?

My cell phone (Samsung Galaxy S5) has recently been getting extremely hot. I've had this thing for a few years, but the screen has been getting very hot for about a week, after a not too long time. When that happens, my phone always starts to lag a bit, but everywhere, including on the home screen or the app menu. I don't do a lot with it, I sometimes play a bit of Minecraft and I'm on the Internet or on YouTube, but otherwise it never got that hot so quickly. I only replaced the battery at the end of December. What is the problem and what can I do about it?

This is normal, I myself had the problem with both the S5 and the S10+, it doesn't matter
