When it comes to the upcoming iPhone 8, the 2017 flagship iPhone, the rumor mill has covered just about every angle up to this point.
But the battery has been left off the chopping table, at least until now. As reported by AppleInsider, KGI Securities analyst Ming-Chi Kuo expects that Apple will make a key change for the upcoming iPhone 8, which, if it pans out, will probably make plenty of future owners quite happy.
According to the report, Apple plans on changing the logic board design for the iPhone 8, reportedly going with a “higher-cost stacked logic board” this time around, which will give the next flagship iPhone longer battery life. Specifically, Kuo says the new logic board design is a “substrate-like PCB (SLP) mainboard,” and, with it, Apple can pack in the battery capacity of the current iPhone 7 Plus, but put it inside a device with a 4.7-inch form factor.
“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.”
Going further, Kuo also states that he believes the iPhone 8’s battery life could be better than the current 5.5-inch iPhone 7 Plus, thanks to the adoption of an OLED display. That display technology is more energy-efficient, so Kuo’s expectations certainly seem possible.
