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 ^^

Conclusion

Green = undervolted / Orange = Stock
Nr60: Average: 397.58mA Total: 68.59mAh in 621Seconds
Nr61: Average: 405.05mA Total: 69.91mAh in 621Seconds

Nr63: Average: 401.14mA Total: 68.86mAh in 618Seconds
Nr64: Average: 403.00mA Total: 76.80mAh in 686Seconds
Nr65: Average: 402.65mA Total: 69.04mAh in 617Seconds
Nr66: Average: 414.53mA Total: 71.28mAh in 619Seconds

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

Longtime Tests

To test out Stock 413 Kernel VS Doomkernel v10 on Ultimate Pure Xz" v1.1 Rom i've made the Same "Normal" Benchmark test again.
The phone was fully charged and the Screen brightness set to Minmum.
Test was running from 100% to 50%
Stock test was made right after charging full, Doomkernel v10 test was made after charging full,then booting into recovery flashing doomkernel and THEN started testing. (You can see this in the Graph that the first few lines are higher.)

Stock 413 Kernel:
4hours 15 Minutes
Average power: 387.04mA Total 1'644.51mAh


(Screenshot was made long afterwards! thats why it' shows 38% but the green line stops at 50%!)


Doomkernel V10
4hours 11 Minutes
Average power: 395.37mA Total 1'652.45mAh


(Screenshot was made long afterwards! thats why it' shows 42% but the green line stops at 50%!)







Edit: Just for these People wondering.i've continued the Test from 32% to 1% Battery with Maximum Screen Brightness.
Average of 593mA Powerdrain.

There will be no tests with 2265mhz!
You wonder why ? Check out CPU Temperature on 1500mhz ! 73C and 52C Battery are horrible for a phone ! Thats the Absolute limit i want my phone to run for a longer time span.
And well, just take a quick look at the Benchmark after 6 Minutes! Battery is still cold, but the CPU is on 85C !


So the next test will be 2 Cores on 1500mhz! wonder how much longer it will last.
Edit coming soon.

Conclusion:
Screen on Time:
Total Idle: 19h 43min
300mhz load: 7h 50min
1036mhz load: 4h 14min
1497mhz load: 3h 7min
1497mhz 2cores: 5h 23min

going from 4 cores to 2 cores under 1500mhz full load gives a plus of 2hours and 15 minutes!
Now the question is: How does the "race to idle" affect this! will a "normal" Benchmark with only 2 cores also save battery, or is the extended time on the higher frequency going to be roughly the same Battery drain but the phone will just be slower ?

And the next thing i'll be testing will be undervolting 4 cores on 1497 mhz, undervolted to the maximum. will it save battery? how much ?

Hey Haldi,

Your thread is really great thank you!! Just I've got 2 questions because I don't have the Z2 yet. So first, does doomkernel v10 or stock kernel use more power with mp_decision and ondemand? And does Stamina Mode underlock or do any other improvements to the cpu to save power, if yes does it do it with doomkernel too or is it only supported by stock kernel?

Thanks

Doomkernel v10 and stock are roughly the same. but you can undervolt doomkernel and profit a lil bit.

Stamina mode does ONLY restrict internet access! but there is a "restricted performance" mode from Sony which underclocks the Smartphone.
But you can use FauxApp /noFrills/setCPU/KernelTuner or any other similar app to manually underclock the CPU and GPU as you like.

Thanks for your answer . There is something left I want to know, the "restricted performance" mode works only with the stock kernel or with doomkernel v10 too? I want to know it because its nice to have a setting for underclocking the cpu so I don't have to do it everytime maunually.

Undervolted the frequency 1497mhz from 850 mVolts to 742 mVotls thats 108mVolts less !

Conclusion:
The Batterylife increased from 3hours 7 minutes to 3hours 40 Minutes, this is a plus of 17%.
The end Temperature after the test sank from 73C CPU and 51.7C Battery to 66C CPU and 48.2C Battery.
All this just by undervolting 100mV.

It's a quiet thread but I just wanted to let you know I use it alot.

Appreciate your work.

BTW: Any opinion on intelli-thermal?

Nah.
Rarely use it. My phone doesn't really go over 70C CPU temperature. I don't have such demanding Tasks.
