[Galaxy S 4 Mini Q&A, Help & Troubleshooting] PrinceGz:
I've been doing a bit undervolting, with some success in terms of lowering the voltage, but no discernible battery life improvement. The battery life must be better, but I can't really detect any difference.

Essential stuff:

Kernel: 3.4.0-f4ktion_lp_2.3.1-eur_lte (2015 Jun 20)

ROM: f4k's 5.1.1 CM12.1-20150620-UNOFFICIAL-serranoltexx

All voltages were changed in 25mV increments. Stability Test v2.7 was run for 30mins to establish a semi-stable safe minimum voltage (after I had established the highest voltage which either immediately froze or crashed in some way within a few seconds). It's worth noting that adding 25mV to the highest voltage which quickly crashed, allowed my device to pass the 30min test at that speed every time across all speeds.

1728MHz: 1175mV stock, 1025mV passed (-150mV)

1674MHz: 1150mV stock, 1000mV passed (-150mV)

1566MHz: 1125mV stock, 975mV passed (-150mV)

1458MHz: 1100mV stock, 925mV passed (-175mV)

1350MHz: 1075mV stock, 900mV passed (-175mV)

1242MHz: 1050mV stock, 875mV passed (-175mV)

1134MHz: 1025mV stock, 850mV passed (-175mV), this one crashed immediately at 825mV

1026MHz: 1000mV stock, 700mV passed (!)

This leads me to suspect the lowest voltage which can actually supplied by the hardware (at least with this kernel) is 800mV.

For a safety margin, I run my device with an extra 50mV above the voltage which passed the 30min test, and it seems rock solid as it is at stock voltages.

Overclocking has been pretty much a waste of time as the device temporarily throttles back from 1836MHz to 1728MHz within a few seconds of running anything very demanding with it locked at maximum speed (Performance governor). It never throttles below 1728, but with no way of forcing it to stay at a higher speed for the duration, it is impossible to check the stability.

It did crash immediately at 1050mV @ 1836MHz, and 1075mV seemed okay for as long as it would stay at that speed (the same voltage I use all the time at 1728MHz after adding my safety margin).

I did find that when I reduced the minimum speed below 384MHz, down to 270MHz and then 162MHz, that the device would spend an increasing amount of time jumping up to middle speeds (around 918-1242MHz) according to the "time in state" list, such that on overnight runs it seemed to use more battery power than at 384MHz-- as such I think Samsung/Qualcomm probably have set the minimum to 384MHz for a good reason.

I'll probably revisit 1836MHz and higher at some point; I'm sure one of those thermal related settings can force it to not throttle back so forcibly.
[Galaxy S 4 Mini Q&A, Help & Troubleshooting] martynas:
After some trials, decreased a bit more and stable with:

Up to 810Mhz - 700mV

918 - 750mV

1026 - 800mV

1134 - 850mV

1242 - 875mV

1350 - 925 mV

1458 - 950mV

1566 - 1000mV

1674 - 1025mV

1728 - 1050mV

With this setup have 2h+ SOT, 2h+ talk time, 2h WIFI or data, 2h non sleep Bluetooth connection - in 48 hours of standby and ~7h awake. 2g connection.
[Galaxy S 4 Mini Q&A, Help & Troubleshooting] xtspot:
Thank you for this information :

I am trying your value but I configure less voltage for high frequency :

Up to 810Mhz - 700mV

918 - 750mV

1026 - 800mV

1134 - 850mV

1242 - 875 mV

------ I change from here -------

1350 - 900 mV

1458 - 925mV

1566 - 950mV

1674 - 975mV

1728 - 1025mV -> Crash at 1000 mV when using with Waze and iCoyote at the same time.

----------------------------------------

For high frequencies I am testing them during 3 days. But low frequency under 1242, I am just now using your frequency.

Yes, i have to adapt my signature but i will do it after a longer test.

I bring here my result after some days ...

Is there a way to undervolt under 700 mV ?

I know that there is a way to overclock over 1728 Mhz. With this file : 90hardlimit_2.05GHz.zip. In the same way I am asking me if there is a way to unlock undervolting to go under 700 mV.

Any Idea ?

---------- 08:21 PM - 16th October 2016 ----------

Bad news I have some unwanted reboot ... I have to test each frequency speed. ...

---------- 09:00 PM ----------------------------------

I find it : 1242 Mhz crash at 875 mV. I need to set a bit higher at 900 mV. I hope it will resolve my problem.

I was using the program StabilityTest. Whit this tools it was very easy to find the problem.

I will publish a new update of the list of my voltage/frequency after I install the new Kernel from DarkFrenzy. He will give us the possibility to undervolt under 700 mV.
[Galaxy S 4 Mini Q&A, Help & Troubleshooting] PrinceGz:
It seems we are all pretty close on which voltages are stable on our devices. It goes without saying that every individual SoC in the phone is going to be different from any other and that its undervolting limits and overclocking performance will vary from someone else with the same model of phone.

With my experience of overclocking, and the limits of undervolting, what I would say is that the starting point for all of this should be the clockspeeds the CPU tends to spend most of its time at. In my case it is 384MHz (the normal lowest speed), 918-1242MHz (usual speed it increases to in normal use), and 1728MHz (maximum). You can check which speeds the CPU spends most time at in any decent tweaking tool, and it should be critical to undervolting.

I've read elsewhere that reducing the CPU speed below 384MHz is actually counter-productive, due to the SoC design (it is very efficient at that speed, and it is the best balance between running at lower speeds for longer periods or partially shutting down). Besides, at speeds as low as that, it is already well beyond the lowest speed where it can work with a lower voltage. There is an absolute lowest voltage limit regardless of how slow a processor is clocked, and for this device it is well above 384MHz, probably at least 702MHz. It doesn't matter how slow you clock a digital circuit, there will be a fixed minimum voltage required for it to work correctly.

The top speed is where most of the power will be used by the SoC, and is where most attention should be paid. The three of us seem to have found that 1075mV @ 1728MHz seems to be about the lowest which works reliably. That's a useful reduction from the default of 1175mV. I passed a 30min stress-test at 1025mV (xtspot crashed at 1000mV like I did), martynas mentions 1050mV as good.

The intermediate speeds are the interesting ones. 918-1242MHz. 875mV @ 1242MHz seems to be the lowest voltage for all three of us at that speed.

Those voltages are fine for a piece of kit you are playing about with, but for stability in regular usage, I'd throw 50mV on top of the minimums to be safe, much like with my PC. It's not much fun if your phone crashes just when you want to use it on a night out!

Hi pal,

Have you tried with another cpu governor, like SmartMax or another one??

Thanks for sharing this info :good:
[Galaxy S 4 Mini Q&A, Help & Troubleshooting] xtspot:
With the new kernel from DarkFrenzy, It is now possible to undervolt under the 700 mv

Here are the list of the value that I am using, I am made a Stability Test during 10 minutes, on the low voltage : I will perform a longuer test and I will update those value if necessary.

Freq Voltage

162 mhz - 400 mv

270 mhz - 400 mv -> 450 mv

378 mhz - 400 mv -> 450 mv

384 mhz - 500 mv

486 mhz - 550 mv

594 mhz - 550 mv -> 575 mv

702 mhz - 550 mv -> 575 mv

810 mhz - 600 mv

918 mhz - 750 mv

1026 mhz - 800 mv

1134 mhz - 850 mv

1242 mhz - 900 mv

1350 mhz - 900 mv

1458 mhz - 925 mv

1566 mhz - 950 mv

1674 mhz - 1000mv

1728 mhz - 1025 mv

1836 mhz - 1050 mv

1890 mhz - 1100 mv

1944 mhz - 1100 mv

1998 mhz - 1125 mv

2052 mhz- 1150 mv

------- update 18/02/2016 at 05:00 pm --------------

Take care I got a crash after 1h30 of testing with program StabilityTest, but when the message was shown I didn't push on the right button, and the message go away, thus I don't know at wish frequency the crash append. I will start another test, and I will give the result. But during the day, in normal use, I didn't get any unwanted reboot.

------- update 18/02/2016 at 11:15 pm --------------

I try a second test with StabilityTest. It hung at 594 Mhz. I increased the voltage for that frequency and the next one.

------- update 19/02/2016 at 10:30 Am --------------

Again unwanted shutdown at 270 Mhz -> increased at 450 mv and the next one also.

Hi,

The long awaited 4.4 is rolling out.

Can I update via OTA or PCC if I have an UNlocked bootloader? If not, how can I update my device?

I unlocked it through Sony's official website on 4.3.

Thanks.
[Xperia Z1 Q&A, Help & Troubleshooting] HellRoot:
Wait until an ftf comes and then flash it

If you don't know what you are doing then don't unlock your bootloader
[Xperia Z1 Q&A, Help & Troubleshooting] KarimSalloum:
What makes you think I don't know what I'm doing? because I don't know if OTA still works when you unlock the bootloader?

This isnt a device out of Cupertino, if Sony wants to lock the bootloader and make it a headache to get root, this isn't Android's philosophy.
[Xperia Z1 Q&A, Help & Troubleshooting] gregbradley:
No,

The only way would be to relock the boot and then OTA or PCCompanion.

Trying an OTA with an unlocked boot can lead to a brick (As mentioned on the warnings on the Sony website) and PCCompanion updates will fail once it sees the "Modified" software of an unlocked bootloader.

As said above, if you want to keep an unlocked boot, you need to flash a FTF when they appear, or relock, update and unlock again.

If you didn't install Diagnosis before installing the Samsung update that comes with GDR3 (it's not GDR3 itself that's the problem, it's the Samsung firmware update), then you will need to roll back to an older ROM.
