It will include 5G connectivity instead of 4G as seen in the iPhone SE (2020).
The upcoming iPhone is rumored to have 3GB of RAM and come with up to 128GB of storage space.
It will also have improved battery life.
My bad, 2023/2024 model would be 4th generation.
There is no official word on the upcoming iPhone SE models from Apple yet.
Keep watching this space for more updates!
