Ran a quick test focused on iPhone heat generated while using the Roon App compared to Rose App. Phone sat on a 77F wood table during test. Started same song on both apps and allowed the apps to continue playing related content no physical interaction. Used an IR thermometer for testing.
Closed all apps and took starting temp: 86.1F
Ran Rose App and played music for 30 minutes: 86.3F
Ran Rose App with Roon App open in the background (unused) for 15 minutes: 92.4F
Closed all apps and ran Roon App only for 15 minutes: 105.4F Switched Roon App from light to dark theme
Ran Roon App for 15 minutes: 109.5F
Closed Roon App
Ran Rose App for 5 minutes: 96.7F
After another 15 minutes: 86.4F
Temp was taken in the same location on the phone screen each time. Shown in photo.
Curious what’s causing this heat when the phone is “just” controlling a Nucleus that should be doing all the heavy lifting.
Makes sense. Just wondering the cause considering the Rose App creates almost no heat. Maybe apples and oranges, but if running the Roon App on my phone is processor intensive I’d like to know why. Shouldn’t it just be an interface for the nucleus?
Additionally, I’ve been monitoring battery power while using the Roon App only. At this point, on this phone, using dark theme, battery consumption is 5% every 10 minutes. Having just had COVID for 10 days and surfing the web ALOT, I know that web surfing, watching YouTube, streaming YouTube to my TV all day leave me with more than 50% battery after 15 hours of extra intense use.
Yes, I did a delete/re-install on the phone and deleted the only other instance of the Roon App on the network - running on my MacBook Pro. So the only device running Roon and connected to the core at the time of the test was the iPhone 13 Pro. Force quits have made no difference. I’ve read posts showing others have experienced the heat issue, but I didn’t read any conclusions about it. I imagine a lot of the Roon Community are in a food coma right now.
