The app make heating iOS devices

[congcoi123]

Hi folks,

I am using the Libgdx framework to develop an application that contains network processing. There are no issues with the Android app version, however, when users use the iOS version, their devices significantly get hot after 10 minutes.
I tried to debug and profiler the app in Android Studio but did not find any potential problems, then I carried on to check the iOS version by using the Xcode tool Instruments, however, I had no idea how to check all other info but the thermal data.
As I am not sure which might be the root cause for it, I would like to ask if any of you were struggling with the same issues, or is there any workaround to catch the bugs or resolve the current problem?

Thank you so much for your time. Any feedback is appreciated.

From the screen above it seems like CPU usage is low. What about GPU usage ? Probably it causes the heat

Hi @dkimitsa, thanks for your comment, I am attaching another screenshot that indicates the CPU usage.

and it show same almost no CPU usage. Can you check GPU (not CPU)

Hi, thanks. I was trying to look for a way to record the GPU usage but was not able to find anything. Could you please let me know how to record that kind of information?
