The iPhone XI will have a 5.8-inch display, with its larger counterpart, the iPhone XI Max, to have a screen of 6.5 inches.
But the most noticeable change to the updated smartphone is its camera.
Taiwan-based TF International Securities Apple analyst Ming-Chi Kuo said in a briefing note last week both the 5.8-inch and 6.5-inch models would have the 12 Megapixel, triple lens rear cameras.
He said it would be “one of the new 2H19 iPhone’s major selling points”.
The camera will allow ultra-wide angles and enhanced zoom.
Images also show the new device may have a round mute button that slides down the phone, replacing the original horizontal one.
The lightning port will be making a comeback and, with its bigger battery, the phone will be slightly thicker than the X.
The new leaked images come days after case mouldings of the phone were leaked.
