iPhone SE 2 Release Date Unknown
If you want a smaller iPhone and you want it in the near future, you'll have to upgrade to the iPhone SE.
Apple is reportedly working on a successor for the iPhone SE, but it's unclear when it'll arrive and what'll have on board if it does.
iPhone SE 2 release rumors in 2018 pointed to an arrival in three windows: Apple's spring window in March, the WWDC 2018 in the summer, and the company's fall release window. None of these panned out
We've also heard that the company might launch a new iPhone SE in late 2019, but the most reliable sources agree that Apple will only launch three iPhone models in the fall.
If an iPhone SE 2 does land it'll obviously usurp the iPhone SE as the go-to small screen iPhone option. Rumors have hinted at design improvements and performance upgrades.
If you're determined to wait, you'll probably have to wait until 2020. If nothing materializes, you might have to go with the iPhone SE or an alternative.
