2018 IPhones to get more powerful batteries
Reputed iPhone analyst, Ming-Chi Kuo of KGI Securities writes that Apple is planning to increase battery capacity for next year's iPhones by borrowing the L-shaped battery unit last seen on the iPhone X.
Additionally, he predicts it will come to both the 5.8-inch OLED model and the 6.5-inch OLED variant.KGI predicts that the 5.8-inch iPhone introduced next year could have a battery capacity of between 2,900mAh and 3,000mAH. Currently, the iPhone X packs 2,716mAh of power, so that means we could see an increase of as much as 10 percent come next year.

In addition to the 5.8-inch and 6.5-inch OLED iPhones that Apple reportedly has planned for next year, there’s also a 6.1-inch LCD model on the table. This device will likely retain the rectangular battery design as a cost saving mechanism, though it too can expect an increase in overall capacity.The 6.1-inch LCD model is looking to be a budget-focused device, with Apple also reportedly reverting to a metal back design that will likely mean no support for wireless charging.
