1. A portable electronic device comprising:
a display; and
an enclosure at least partially surrounding the display and including a cover glass that is chemically strengthened, positioned over the display, and comprises:
a first portion defining:
a first front surface and a first rear surface;
a first thickness between the first front and the first rear surfaces; and
a first stress pattern along the first thickness and comprising a first front compressive stress layer that extends to a first depth from the first front surface; and
a second portion defining:
a second front surface, a second rear surface that protrudes with respect to the first rear surface, and a side surface;
a second thickness, greater than the first thickness, between the second front and the second rear surfaces; and
a second stress pattern, different from the first stress pattern, along the second thickness, wherein the second stress pattern is asymmetric and comprises a second front compressive stress layer that extends to a second depth from the second front surface that is greater than the first depth.

8. A portable electronic device comprising:
a display; and
an enclosure at least partially surrounding the display and including a cover glass comprising:
a first chemically strengthened portion defining:
a first thickness between an exterior surface and an interior surface of the first chemically strengthened portion; and
an asymmetric first stress pattern along the first thickness, the asymmetric first stress pattern comprising a first exterior compressive stress layer extending to a first depth from the exterior surface of the first chemically strengthened portion; and
a second chemically strengthened portion defining:
a second thickness, greater than the first thickness, between an exterior surface and an interior surface of the second chemically strengthened portion, the interior surface of the second chemically strengthened portion protruding with respect to the interior surface of the first chemically strengthened portion; and
a second stress pattern, different from the asymmetric first stress pattern, along the second thickness and comprising a second exterior compressive stress layer extending to a second depth from the exterior surface of the second chemically strengthened portion, the second depth greater than the first depth.

15. A mobile phone comprising:
an enclosure defining an internal cavity, the enclosure including a chemically strengthened glass enclosure member comprising:
a first portion defining a first stress pattern along a first thickness of the first portion, the first stress pattern comprising:
a first exterior compressive stress layer extending from an exterior surface of the first portion to a first depth; and
a first interior compressive stress layer extending from an interior surface of the first portion to a third depth; and
a second portion defining a second stress pattern along a second thickness of the second portion, the second thickness greater than the first thickness and the second stress pattern comprising:
a second exterior compressive stress layer extending from an exterior surface of the second portion to a second depth that is greater than the first depth; and
a second interior compressive stress layer extending from an interior surface of the second portion to a fourth depth that is less than the second depth, the interior surface of the first portion recessed with respect to the interior surface of the second portion; and
a display positioned within the internal cavity.
