Liquid glass is one thing, but I want my 13 mini to go back to not being janky and glitchy and not suddenly dropping dead when the battery hits 5% again. These are new problems since the update.
I updated my old/spare phone - an iPhone SE3, which I think has a similar processor and memory (A15 and 4GB). It became a lot more sluggish. I learned my lesson not to upgrade my main phone, also an iPhone 13 mini.
I also noticed a disappointing slow down on a 9th gen iPad, which has even older internals. Actually, perhaps I should be quickly looking into downgrading that if it's possible.
