The iPad mini has a benchmark of 261 single core and 493 multi core. That's exactly what I got on iOS 7. But since updating to iOS 8, benchmarks are significantly lower. The first time I ran it I got 256 and 484. I restarted and got 250 and 459. The worst i got was 201 and 366. The best was 260 and 492. Has this happened to anyone else?
