Apple's upcoming anniversary iPhone will pack a lot of battery power. And this has a lot to do with its size.
The iPhone 8 will reportedly utilize a larger battery that will allow it to have longer battery life. According to Apple Insider, the iPhone 8 or possibly the iPhone X will likely sport a 2,700 mAh L-shaped 2-cell battery pack. What makes this even more impressive is that the upcoming Apple flagship smartphone will be almost as small as the iPhone 7 which measures 4.7 inches but will have a battery almost as big as the one used by the iPhone 7 Plus. The iPhone 7 uses a 1,960 mAh battery while the iPhone 7 Plus has a 2,900 mAh battery.
As well-known Apple analyst Ming-Chi Kuo explained, the large battery in the rather small package is supposedly made possible by the fact that the components inside the device are smaller than what its predecessors used. The smaller components mean there is more space to use a bigger battery thus giving the new iPhone better battery life. BGR noted that the iPhone 8 will use a substrate-like PCB mainboard or a stacked logic board design allowing such feat to be possible.
Kuo also noted that there will likely be no major breakthrough regarding battery technology in the next 3 to 5 years. With the stacked logic board design, however, Apple will be able to put as much battery inside a device. So far, however, the stacked SLP will only be used on the iPhone 8.
The battery life of the iPhone 8 will also be better because of the use of an OLED display. As a matter of fact, Kuo predicts that the new Apple handset's battery life will be better than that of a 5.5-inch phone that has a traditional LCD display. All these details plus the rumor that Apple is finally introducing wireless charging will certainly make the iPhone 8 perform great when on the road.
