Apple reportedly plans to pack a much bigger battery inside the new 4.7-inch iPhone set to be revealed later this year.

In his latest research report, Apple analyst Ming-Chi Kuo claims the smaller iPhone will be the first device to feature a stacked logic board design to bring better battery performance.

Kuo’s note to investors says battery life on the 4.7-inch iPhone 8 will be comparable to that of a 5.5-inch iPhone.

The new stacked logic board will provide more space for a larger battery. Switching to OLED displays will also help Apple eke out battery gains over traditional LED displays.

Here are the details from Kuo’s note:

“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.”

The iPhone 8 is expected to be announced at an event in this fall. Apple is reportedly already lining up production, having ordered 160 million OLED panels from Samsung.

Other new features on the 2017 iPhone could include retina scanning, a Touch ID fingerprint scanner embedded in the display, better cameras and more.
