Apple is expected to launch the iPhone 13 series next month with a boatload of new additions on the inside as well as outside. Today, a Taiwanese research firm has highlighted what it expects from Apple's upcoming flagship smartphones.

There is a bevy of changes coming to the iPhone 13 series that did not make it through last year with the iPhone 12. For instance, a higher 120Hz refresh rate. This time around, Apple will potentially incorporate a panel with variable refresh rates ranging from 1Hz to 120Hz in order to save battery life. TrendForce's investigations coin that the iPhone 13 series will feature a more powerful 5nm+ chipset which will presumably be called the A15 Bionic. It will boast mmWave 5G in the US as well as other countries.
