Problem with MacBook Air overheating and battery draining

Try and boot the Mac in the safe mode to see if the issues persist

If the issues don't persist in the safe mode they're most of the times caused by an external piece of software

Start up your Mac with Apple silicon in safe mode

3. Press and hold the power button on your Mac until “Loading startup options” appears.
4. Select a volume.
5. Press and hold the Shift key, then click Continue in Safe Mode.
6. The computer restarts automatically. When the login window appears, you should see “Safe Boot” in the menu bar.
