Undervolting is one of the famous tweaks for Android
If you are planning to test out the lowest voltage your device could probably stand, you have definitely come to the right place. This article is the part two of the first topic, The Complete Android Overvolting Guide. In the previous guide, you have learned generally on undervolting such as what is undervolting, advantages and disadvantages of undervolting. With that, I believe that you are ready for the next step which is performing the undervolt process. As usual, the disclaimer is I will not be responsible for your action in the case of your bricking or damaging your phone with this action. This article serve as a guideline for you and you should attempt this at your own risk. Remember to be safe and here we go!

If you have already grab yourself with either the free or paid copy of Voltage Control or SetCPU, you have done the first step. Great! Now, what you need to do to start off the undervolting are as below:

Know your device limit
Start with the highest figure which is 1200 Mhz. What you need now is to reduce the voltage by -50 and at an average, you can reduce it straight to 1200 mV. From here, you got to reduce -25 mV slowly to check what is the lowest point. If you are already scratching your head on what the heck I am talking about, I mean  -25 mV once, and use the phone normally for the next 1-3 hours. If there is no hang or sleep of death, you are save to -25 mV again. Well, what happens if your phone hangs in the midst of something you are doing? Just revert back to the last safe value and you will be fine. In this case, with the current value, add +25 mV and you have found the most stable voltage for your device.

This is a long process as you are going to perform these tests for every speed. Yes, this is tedious but you are bound to find the best battery life and performance once you have fully completed it. Now, if you are wondering if I could provide you a guideline as a head start, yes you are right! 

I know there are many who can't wait for me to throw in the exact details of the voltage setting. Therefore, I am going to list down below, voltage settings of the three most common kernels I used.

Siyah kernel and N.E.A.K. kernel
1200 Mhz - 1175 mV
1000 Mhz - 1150 mV
800 Mhz - 950 mV
500 Mhz - 875 mV
200 Mhz - 850 mV
100 Mhz - 825 mV

Red Pill kernel - I use -25 mV for all as the developer of the kernel had already modified the settings.

How to further test your device and undervolt settings?
There are two ways you can test your new undervolt settings. What you can do first is to install the latest stress tester from Android Market and if my memory doesn't lie to me, SetCPU app does comes with that. Once you start the stress test, do not touch it and the phone might get hot and not responsive. Try run it straight for a few hours (minimum is 1 hour) and if the phone is still on and functioning when you want to end the test, the settings are stable. If the setting are not stable, you will noticed that the phone might already in sleep of death status or even turned off. 

So what is the second way? The second way is use your smartphone as usual daily. If the setting is correct, you will not experience any issues with it whenever you are using the phone. As easy as that! Being said that, good luck and all the best with your undervolting process for your Android smartphone.
