4 Increase Device Performance
Typically, beta releases of iOS are a bit laggy and can directly affect the performance of your device (they are beta versions, after all). Despite this, many users have reported that iOS 12 public beta actually improves the performance of their devices.
This shouldn’t come as a surprise — Apple highlighted performance as one of the key drivers of iOS 12. In fact, Apple stated that iOS 12 would also increase the performance in older iPhone models, too. Highlights include faster scrolling, quicker app launching, and better keyboard responsiveness.
