[Xperia Z2 General] Haldi4803:
Undervolting Tests!

6 Tests made! in a Stock/Undervolted/stock/undervolted/stock/undervolted sequence.

undervolted were the frequencies most used with onDemand governor:

300mhz - 631mV

960mhz - 696mV

1190mhz - 726mV

1574mhz - 776mV

2265mhz - 903mV

Stock Voltages for these frequencies are:

300mhz = 775mV

960mhz = 780mV

1190mhz = 810mV

1574mhz = 860mV

2265mhz = 975mV

fresh boot, let it rest for about 10 minutes, 10 minutes pre-heating and then benchmarking nr 60-65 in a row.

For testing purpose benchmark nr 66 is made with a global -72mV and not only these frequencies. results are worse ^^

Except Benchmark NR 62 which seem to be too high (guess something sync in the Background....) we don't really see a difference from undervolted or Stock Voltage !

Strangely benchmark nr 66 with Global undervolting of -72mV is worse off than the others ^^

As my battery was below 15% and i wanted to flash Stock kernel i could NOT repeat Benchmark nr 66 :(

As i switched to Stock Kernel (for Charchign Benchmarks...) i made a short Test of the exact same thing. As i went below 3% Battery i could not recreate this test! But as it looks i'll definitly have to, once it's fully charged. Seems way to high vs Doomkernel v10
