It takes 28" to do it with the RPN-15C emulator on my iPhone.
On a real HP-15C it takes probably much longer.
5 seconds on my outdated iPhone 4s with HP-15C emulator by HP:

Code:
001- f LBL A 002-   CHS 003-   y^x 004- g RTN

0 ENTER 1 f Integrate --> 1.291285997 (blinking, but that's another story)

Estimated +4 hours on a real HP-15C.

As a comparison the following return the same result (no blinking, of course!) in 13.7 and 13.4 seconds, respectively, on my 30-year old HP-15C:
Code:
 001- f LBL A            001- f LBL A 002-   0                002- f MATRIX 1 003-   STO 0            003-   8 004-   9                004-   STO I 005-   STO I            005- f LBL 0 006- f LBL 0            006-   RCL 1 007-   RCL I            007-   RCL+ I 008-   ENTER            008-   ENTER 009-   CHS              009-   CHS 010-   y^x              010-   y^x 011-   STO+ 0           011-   STO+ 0 012- f DSE I            012- f DSE I 013-   GTO 0            013-   GTO 0 014-   RCL 0            014-   RCL 0 015- g RTN              015- g RTN

Cheers,
