Xiaomi 15 Ultra Lagging Issues: Why the ‘Divine Device’ Has Performance Problems & How to Fix
I eagerly purchased this device right after launch, but after a week of use, my excitement has turned to frustration. Despite splurging on the premium version with higher refresh rates and expanded memory, the phone keeps freezing inexplicably. I specifically chose this brand because I trusted Lei Jun’s reputation—otherwise, Huawei would have been my pick.
Coming from a flawless two-year experience with my OnePlus 11 (which never froze once), this has been particularly disappointing. At this point, returning it seems more trouble than it’s worth, but I can’t help wondering: how did such a promising device end up so problematic?
