Check in device care for battery usage. This will usually show which service or app is using more battery power. Also closing all apps and restarting device helps.

When a phones starts to overheat it becomes a dangerous device and there is some kind of battery issue. I would contact Samsung Customer service for assistance or if you have insurance with your phone carrier send it in and get it fixed or replaced.

I am sorry to hear your device is overheating and charging slowly as a result, and can understand the concern and frustration.

Whether you're using a phone, tablet, smartwatch, or earbuds, all Galaxy devices have a set temperature range, where they operate at their best. While they may feel warm under certain conditions, like charging, this does not affect the device's lifespan or performance. However, if your devices get too warm, it could cause some issues. Give this link a try: https://www.samsung.com/us/support/answer/ANS00076952/ You can also try clearing the cache partition of the phone.

  1. Turn off the device.
  2. Press and hold the Volume Up key, then press and hold the Side key.
  3. When the green Android logo displays, release all keys ('Installing system update' will show for about 30 - 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight wipe cache partition.
  5. Press Side key to select.
  6. Press the Volume down key to highlight yes, them and press the Side key to select.
  7. When the wipe cache partition is complete, Reboot system now is highlighted.
  8. Press the Side key to restart the device.
