@Murdoa it is a little bit hot. Do you have any problems when you're gaming though? Also, do you have an Exynos or Snapdragon variant? If you aren't having issues, I wouldn't worry too much about it. If the processor gets too hot there are automatic cutoff safeguards.
I have a snapdragon version. It doesnt feel slow when playing most of the time. No warnings for temperature was been seen and i still have 100% health. So is there something wrong with the phone or i just have an unreliable temp checker app
My Note 10 temperature is around 30°C when I am using the apps like Youtube and Whatsapp. At most 35°C.
But its jumps to 42 to 43°C while I am Playing PUBG. I haven't seen it reach 45°C on my phone ever. 50°C and 70°C are too high. That is not normal at all. During normal use your phone should be in low 30s and during gaming it should low 40s. Nothing above 45 is ok or normal. Also, I think my phone should be around 38 to 39°C while playing PUBG, but because I have this one option on "Disable HW Overlays", it is causing my phone to get hotter than usual while gaming. I have that option on for PUBG because a Samsung's software update messed up the PUBG on my phone locking it to only 40 FPS. But turning that option on gives me 60 FPS again. I shouldn't have to turn that option on to get 60 FPS. Samsung needs to fix this.
I dont use any external app from playstore. I downloaded "Game Plugins" from Galaxy store. Once you open game plugins, there are couple of things to download; Game Booster Plus and Perf Z. I downloaded them both. Game Booster Plus let's you choose how much fps do you want for a game etc. While Perf Z shows you the temperature, CPU and GPU usage, and # of FPS while gaming. So once I have downloaded these and enabled them from within the Game Plugins, then I am able to check device temperature whenever I open any game.
