The good news is that noted mobile analyst Ming-Chi Kuo, of KGI Securities fame, reckons that all three of the 2018 iPhones are going to get a boost in capacity across the board, thanks partly to a new L-shaped battery design. >That L-shape is actually going to be formed by two separate cells linked together, according to a memo written by Kuo and seen by AppleInsider. You'll apparently see that fitted to the 6.5-inch and 5.8-inch OLED iPhones, bumping the capacities as high as 3,400 mAh and 3,000 mAh respectively.
