Heating chipset is actually normal for phone especially for flagship phone. Upto 45°C of temperature of chipset is normal for flagship phone nowadays due to its higher and faster performance as a result more heat it can cause. However, the Exynos chipset is hotter compare to other and if heat up the performance of phone became slower, if playing games frame rate heavily drops and too laggy which make it unplayable. So here's my tips for you for this heat issue base on my personal preferences and experience.
Environment temperature can affect your phone temperature also, so keep your phone to colder environment as much as possible. Don't keep it in a close area such us under your pillow, it can cause heat.
If your playing heavy games, phone cooler or playing in front of your fan can lessen your phone temperature so you can prevent overheat and lag.
If you have aircon in your house using it inside your air-conditioned room/house will surely help your phone to not overheat. I play Genshin Impact in my phone, the highest temperature it reach is 45°C and yes the graphics is set to high and max fps is set to 60. So far the highest fps I reach in this game is 44. Not bad for Exynos 990 chipset. This happen only while playing inside my room with turn on aircon, otherwise it will overheat my phone which would cause very lag.
Using your phone while charging can cause more heat to your phone, so a heavy usage of phone while charging (such as watching video, playing games, video call etc.) will heat up your phone, especially if use in warm environment.
Its too hot here in the Philippines therefore it can affect our phone's temperature. A hot environment can cause heat to our phone so the tips above help you lessen the heat.
Hey there, Shinra! Amazing afternoon! Yes, there are waaaay many factors that may affect your device when we talk about heat up. It is pretty normal, and it may depend on the usage of such device. Your user experiences and tips HIGHLY HELPS fellow members as well to shed some light with the issue and to help somehow alleviate it. Thank you for your support to Samsung. Stay safe and hydrated (our body overheats as well you know, even though we're not equipped with snapdragon or exynos. 😁😉)
Would like to add.. If you wan't your batteries to degrade less over time, refrain using your phone on extended periods especially when the device gets too hot. Heat kills battery faster. This applies to any phone really.
Props to Samsung's battery tech though. I've been tracking my S10+' battery health using AccuBattery Pro, and since launch, I've only lost 13% of my battery capacity.
Same problem having a exynos and not snapdragon. Seems like exynos are prone to heating issue. Even in light use or even charging while the data connection is on.
