Hi... I'm sure Samsung will make it as much as possible. But when you use a large amount of processing power and while you charging the device, heating is a normal thing. Here are a few tips to reduce the extra heat and save the battery.
First, if you have any unwanted apps or apps that are not used regularly, put into deep sleep or just uninstall them. So it won't take background processing and the battery power. Result will be less heating and increasing the battery.
Second, update all of your system apps from play store and Galaxy store. (Better you could update all the apps)
Third, try not to use the device while it charging.
Hi 👋, Don't worry about battery problem but worry about heating problems cause mainly it based on your usage pattern and chipset 😃 , so heating means battery drains very fast 🔋⏩ so try to limit your device heating issue then it will fix battery issue 😊
