In his latest note, reputed analyst Ming-Chi Kuo says that Apple will further increase the battery capacity on the iPhones in 2019 and 2020. The company will be able to achieve this thanks to improvements in semiconductor manufacturing, SoCs and PCBs which would provide space for even larger batteries.
The company would continue to increase the battery capacity on its upcoming iPhones as 3D sensing and AR components and apps will consume more power. Additionally, iPhone variants released in 2019 and later will feature an upgraded TrueDepth camera system at the front which would also be more power hungry. Thus, to negate the extra power consumption, Apple would continue increasing the battery capacity on future iPhones until at least 2020.
While there have been rumors of Apple switching over to a flexible PCB design with its 2018 iPhone lineup, Kuo believes Apple will continue to use radio frequency printed circuit boards (RFPCB) batteries as they are superior to batteries featuring flexible PCBs. After the recent revelation of Apple slowing down iPhones as they get older due to their ageing batteries, it would be interesting to see if the Cupertino company takes some steps to help increase the lifespan of its batteries used in future iPhones.
The analyst reiterated that the 2018 iPhone X would feature a single-cell battery design thereby allowing for a 10 percent capacity increase. The bigger iPhone X Plus featuring a 6.5-inch OLED display will make use of a two-cell battery but the increased internal space would still allow Apple to fit in a 3,300 to 3,400mAh battery on the device.
Despite the inclusion of more power hungry components and the rise in augmented reality-powered apps, the 2018 iPhone lineup should still offer a notable improvement in the battery life department thanks to the use of higher capacity batteries.
