Device overheating issues - Video Calls

[bhavinb98]

Device overheats during video calls. Problem noted in both Android and iPhone devices.

The video quality is already set to low :- Resolution: 320 × 180; frame rate: 15 fps; bitrate: 140 Kbps No other video enhancements are being used.

Agora version being used :- agora_rtc_engine: ^5.3.0

Edit - Maximum 4 people in video calls.

Noticed this as well, although mainly on the 6.0.0-beta versions

Which device you are using? media encoding/decoding naturally costs more than normal mobile activities. The impact of low-end mobile phones will be more obvious.

iPhone 8, One plus 6, One plus Nord are the devices on which the problem was noted without doubt. Will include more devices if they experience the same problem.

Also, only 4 people are in a video call at a time. I believe these devices should have no problem processing video calls with such small number of participants.

For me it's Samsung Galaxy S10E (Exynos 9820 CPU) which I use for debugging via USB tethering.

I also use iPhone XS, and I never see it heat anywhere as much, even though the 2 devices have comparable CPUs from the same generation, which might indicate the problem may be Android-specific.

I mostly work with 6.0.0, and at one point while running a test call on 6.0.0-beta.1, I got a notification in the Android tray saying something like "charging stopped because your device is too hot".

I didn't get that specific message since then, and later versions of 6.0.0 seem to do better, but there are other indications that the 6.0.0 isn't as efficient as 5.x.x yet:

1. CPU usage with 6.0.0 is consistently 25—29%, whereas with 5.x.x it is mostly stays within 15—22% range, on the same codebase and same device.
2. I get 30% less FPS on the same device on 6.0.0 than on 5.3.0 (I already opened a ticket CUS-26828 about it).

I think it's better to raise a ticket to the agora support, cause you may need to share some sentence data so that we can analyze it further.
