Following is link to my effort for Android (free), that might help. It runs my most demanding JavaDraw test, measuring CPU MHz and graphics FPS, as these might change as battery loses power.

It runs 60 passes for duration via typed input, with testing time, MHz and FPS displayed as the tests are running, then all results at the end, if it gets there. The results are also saved to the internal drive (probably not a good idea when losing power). On restarting, the last saved results are displayed.
Following are results on a Nexus 7, where power went off after nearly 4 hours (38 x 6 minutes). This identifies a problem, where the display turns off after a period (pass 17 low FPS - zero for some of the time) and needs the power button pressing to continue.
