In an ideal world, yes, but I'm not going to do a fresh flash (although I may have to if it 'borks' my phone up ), and I'm not about to buy a new battery just yet.

I haven't used the patch yet, so if I do it on my device and graph the differences, over the 4 days (I'll come to that in a sec), then as long as the same conditions are kept over the 4 days, a comparison can be made of the patch only with on my device. Ok the battery will be 3 days older at the end, but I think the difference would be negligible. Oh, no updates or new software must be installed after the control test has been run.

After further thought Day 4 would be a second control test, with no media playing, but with the patches applied.

If other people ran the same test over 4 days then the comparison can be made only with their own data.
