Apple is reportedly planning to launch a new 4-inch smartphone, referred by some as the "iPhone 5se", in March, and the latest schematics leaked online reveal the design of the handset early. The diagrams leaked by popular mobile tipster Steve Hemmerstoffer aka @OnLeaks on Twitter show similarities between the upcoming iPhone 5se and the company's recent iPhone 6 and 6s series.

Hemmerstoffer leaked two schematics of the iPhone 5se — termed the oldest and newest versions — both of which he said were prototypes tested by Apple. There are slight changes in both versions, but a 4-inch screen, the relocated power button, the main Home button and 7.6mm thickness were constant.

The rounded corners and flat edges shown in the leaked schematics along with the speaker grille placed at the bottom of the device resemble the iPhone 6 and 6s series' design. On the rear side of the device, the "oldest" version of the schematics shows a round True Tone flash as seen in the iPhone 6 series while the "newest" version has the old pill-shaped design, Apple Insider reported.

Rumours of the 4-inch iPhone have been steady in recent months, with reports suggesting a launch alongside iPad Air 3 and new Apple Watch bands on March 15. In terms of specifications, the iPhone 5se will reportedly feature an 8MP primary camera with support for Live features, a 1.2MP front-snapper, Bluetooth 4.2, VoLTE, Wi-Fi 802.11ac and an A9 processor.

The Home button will have a fingerprint sensor and the antenna stripes will be seen on the rear side of the device, much like current flagship smartphones. The company is expected to launch a Rose Gold version for the iPhone 5se, which will come with 16GB and 64GB storage options. As for the pricing, it will either be same as the iPhone 5s or a tad more.
