Are 4k and 8k videos too much for the iPhone X to handle? I've watched a few 8k videos on YouTube, not time lapses, just a regular demo video, which I think there's only one with the game of thrones scene. Anyway, it plays insanely great! But after a while I noticed some stutter towards the end. Like it's having trouble keeping up. I know it could be a number of things but I'm pretty sure it's not an isolated issue as I can replicate the stutter on my friends iPhone X. Maybe it's buffering?? I notice it more towards the end of the iPhone's battery.
