Yes, I've tried it on both wifi, and cellular network, force shut all my apps, did a power down and power up of the iPhone, and it still lags from time to time quite noticeably. The thing that I have also noticed is the phone seems to heat up when the lag takes place. Sometimes, say when I'm the middle of a blitz or 5v5 game, if I pause the game for a while, it actually resumes normally, and sometimes the lag persists.
The issue is not exclusive to him, a large number of people have reported it on the NBA Live Mobile subreddit, I am encountering the same issue on an iPhone X so it's not an issue of device age.
