With this it has revived a mid-market brand that the company had discontinued in 2018.
It resembles the form of 2016’s iPhone 7 with a 4.7 inch screen, and a fingerprint ID sensor but not a depth camera for facial recognition, according to reports.
It is powered by the same processor as the flagship iPhone 11 Pro, but lacks multiple rear cameras.
The handset costs the same as the original SE in the US, but is more expensive in other markets.
The iPhone SE is priced at $399 in the US and £419 in the UK.
According to experts, this mid-range phone again could help Apple compete for new customers against rivals such as Samsung and Google, which have a strong presence in that market sector.
The device supports wireless charging.
Its rear-facing camera’s resolution is 12 megapixels and can still create background blur in portrait photos, despite lacking a second lens.
The selfie camera is of seven megapixels.
The iPhone SE goes on sale on 24 April.
