Hi everyone, After updating my Apple TV HD (model A1625) to tvOS 26, I’ve noticed a significant spike in CPU usage—up to 3× higher than before the update. Go from around 40% to 120%

Model: Apple TV HD (A1625) tvOS Version: 26 (stable release) and beta version of 26.1, App downgrade stream due to lack of cpu power

If anyone else is experiencing this, please share your findings or workarounds. Would love to hear from Apple engineers or other developers if this is a known regression or if there’s a recommended fix. Thanks!

I’d like to clarify some details of your post. Reading between the lines I believe that:

You have an app for tvOS.
It implements some some of media streaming.
You’re seeing higher CPU usage in your app on tvOS, which affects your stream quality.

Is that right?

If so, I can only presume that you’re streaming video. It’s hard to imagine audio streaming using this much CPU.

What Apple API are you using for this streaming?

Hi, yes your fully correct, its an app for tvOS We are media streaming VOD and live content. and only on the AppleTV A1625, we see thats there is an effect to the stream quality, and the only diffrent i can spot is the larger cpu usage(Other processes) and we have tried build on both the 26 and the 16.4. And we are using the AvPlayer to stream the content.
