Thanks for posting. Lower than expected scores can be caused by running a benchmark while your device is in low-power mode, or while there are substantial processes running in the background. Lower than expected scores can also be caused by hardware or software issues, which we cannot diagnose.
If you suspect that hardware or software issues could be responsible for your scores being lower than expected, we recommend running a CPU Benchmark 3-4 times over several days. If your scores are consistently lower than expected, we recommend taking your device to a local Apple Store for inspection and potential servicing.
