The battery of the S10e becomes worryingly warm even when the phone is on power saving mode and is not being excessively used. This only started being an issue since I updated the phone when the Samsung OneUI 2.1 rolled out. I haven't checked if this happens while the phone is on charge.
A warm battery could be due to environmental changes and power intense apps running in the background. Try clearing the system cache and monitor battery performance. Battery can also be tested in the Samsung members app. Doubt there is a problem with the battery. Could be a corrupt file after the update.
