All three of the iPhones that were introduced in the year 2018 are going to pack much more powerful batteries. Apple is going to be bringing L shaped battery designs. This is going to allow for increased capacity as well as improved battery life. The iPhone X currently features an L shaped battery structure. KGI is predicting improvements as well as further refinement of the battery technology. Battery life has been a point of contention for iPhone users for a long time.
Thus far, KGI has said that Apple will introduce three new iPhones next year: two OLED models at 5.8-inches and 6.5-inches, alongside a 6.1-inch LCD model.
