iPhone 8 Rumored to Feature Battery Capacity of 5.5-Inch Model in Smaller Form Factor

KGI Securities analyst Ming-Chi Kuo issued a note to clients this morning, obtained by MacRumors, in which he predicted that Apple’s upcoming iPhone 8 would manage to squeeze a Plus-sized battery into a smaller 4.7-inch form factor, possibly having even better battery life than a 5.5-inch LCD iPhone.

This will be achieved by utilizing a pricier stacked logic board design—also known as a substrate-like PCB (SLP) mainboard—that would create additional space inside the device to accommodate a significantly larger battery.
“As battery material tech isn’t likely to see major breakthroughs in the next 3-5 years, mainboard area can only be reduced via stacked SLP, which makes space for larger battery and extended usage time. Thanks to stacked SLP, we expect the OLED iPhone to have similar dimensions to a 4.7” TFT-LCD iPhone, and have comparable battery capacity (equipped with around 2,700 mAh L-shaped 2-cell battery pack) to a 5.5” TFT-LCD iPhone. The battery life of the OLED iPhone could be better than that of the 5.5” TFT-LCD model as OLED panels are more energy-efficient than their TFT-LCD counterparts.”
Were iPhone 8 to use a battery similar to that inside 5.5-inch iPhones, that’d be a 50 percent power boost versus a 4.7-inch device. In fact, iPhone 8 could have even better battery life compared to the 2,900 mAh battery inside 5.5-inch iPhone 7 Plus models.

That’s because the phone will switch to an OLED display which is significantly more energy efficient than its LCD counterpart as it doesn’t need a backlight. The stacked mainboard design could result in up to 80 percent higher manufacturing costs for the component, supporting thesis that iPhone 8 will have a premium price tag of $1,000+.
