no one answered you in 3 pages lol so... check this out, maybe someone else would have this question as well but didn't dare to ask

when doing game tests along with the cpu freqs and temperatures, it gives a certain level of good information if you don't trust your eyes to decide whether the game "lags"

for human eyes, 16 fps is the threshold where the most of us think a dynamic graphics playback shows noticeable stutter, so enjoy reviewing games :laugh:

1026 should be 875mV, since it's already -75mV as default.
[Nexus 4 Original Android Development] yoyoz808:
Hey franco, i know you mentioned a few builds back that there was a patch that dropped the voltage on the 4g like 3mv or something. Is there any way to UV it more? Just curious because that's a major battery killer since I'm on the go alot.
[Nexus 4 Original Android Development] :
Are you guys sure 1000mhz is still undervolted by default? Because if it I run it with - 225mv and it's stable oO.

Anyway. Battery life is still awesome, as usual. Didn't really see any decrease in battery life now that the 4 cores are on all the time to be honest. Great work!
[Nexus 4 Original Android Development] superleeds27:
UV'ing based on this. First time I tried at 1026 it crashed. hve just gone for the -25mv on that frequency for now. 150mv on everything else

1026 at 925mv on a fast chip..

Edit: Using Conservative, with the CFQ settings Franco posted this morning. Will see how this goes. Glad the UV has finally come :)
[Nexus 4 Original Android Development] franciscofranco:
Unbelievable! 5 hours screen on time with all cores always online (minus screen off ofc) its a good proof than hotplugging this **** isn't THAT helpful. Thank you so much. With UV you should save a little bit more, maybe extra 30m screen on time (just an estimate).

My bad. I have this bug on Chrome Canary that doesn't let me see picture attachments correctly. I didn't know there were pictures in the post you quoted (I had seen it previously). I assumed you were the one achieving 5 hours of screen on time.

On another note, I'm using conservative right now. My idle battery consumption is pretty good. I'm not quite sure about on screen battery since I've only had the screen on for about 35 minutes and I'm at 87%. Granted I played Temple Run 2 for 15 minutes, but hey.
[Nexus 4 Original Android Development] Testraindrop:

uv setting after reboot

thanks franco for the amazing kernel.

i've been with #61 for a few hours, every things seem smoother, and the phone does not generate much heat. the battery drain is as good as previous versions.

trying to optimize the uv setting for my n4, with #61 on stock.

so far, i've had to do a couple of recoveries.

the phone rebooted when i set the voltage a little bit too low for sure. then the phone kept rebooting, i had a chance to enter the franco app and i saw that the app kept those too low voltage settings, even i did not check the "set voltage on boot".

just got a try, the voltages come back to default if the reboot is manual/normal.

i've not noticed this kinda issue with other cpu apps or kernels.

Also will I have to keep running the echo 80 > etc etc etc command to reduce the sensitivity of the vibrator after every update or are those settings persistent between updates.

extreme undervolting will make your device unstable and some times even end up with a boot loop, that is all.

If your device is stable and not boot looping with the voltages that you have set then your not using extreme undervolting

Re: [KERNEL][GPL][N4] franco.Kernel - r53

Too low voltage, even if it doesn't make your device bootloop, can be unstable.

The CPU will do more mistake and will have to correct them, but you don't see this. Kind of hard to say how much we should UV

With a few words the things, which caught my attention, are:

1. don't expect too much battery saving because of undervolting. A figure of 2% is mentioned

2. do stability test when your battery is nearly empty, not only with full charge.

3. extreme UV could use more power because of correcting errors, as Bluewall said above. Here's a quote from there (values from different device):

The points are for a different phone but still seem strong and plausible?

[Nexus 4 Original Android Development] j.llorente:
Yes but...are you sure? How you can know if the A15-Cortex L2 are configured for support ECC? We're using A15 not A8. I think that we need too more benchmarks with the power results to confirm that

ARM:

The L2 cache can be configured to support ECC. Some memories within the L2 memory system support ECC when configured. For core instruction and data accesses resulting in an L2 cache hit, where a single-bit error is detected on the data array, the L2 memory system supports in-line ECC correction. Uncorrected data is forwarded to the requesting unit, and in parallel, the ECC circuitry checks for accuracy. If a single-bit error is detected, any uncorrected data returned within two cycles before the error indicator must be discarded. The L2 memory system begins to stream corrected data to the requestor.

After it is determined that no data is being transferred, the L2 memory system shifts back to return uncorrected data until the next single-bit error is detected.

For all other single-bit ECC errors detected, the request is flushed from the L2 pipeline and is forced to reissue. The tag bank where the single-bit error occurred, performs a read-modify-write sequence to correct the single-bit error in the array. The request is then reissued.

Hey guys, I had something odd happen today. I noticed at the end of my work day that my battery was at 11% when it is usually somewhere around 35 to 40%. When i went into the battery stats screen I saw that maps and phone where unusually high. It looks like my phone thought the GPS was enabled and running for hours (I used it for roughly 20 minutes and disabled it when through) and the phone app kept the phone awake for 5+ hours after a 2 minute phone call. The only thing I've done is install cm 1/27 nightly (updated from a few nightlies back) and update Franco's kernel from 34 to the newest 53. I posted in the cm thread as well to see if i can find any help there too. Can anyone think of a reason why these two apps would be acting like this?

Re: [KERNEL][GPL][N4] franco.Kernel - r53

I believe some of my UVs are more than 250s compared to stock voltages. I don't do it globally, I do each frequency separately. Start with the lowest frequency and use the stability test app from market to test to see if it is stable. While you test the stability make sure to set your min and max to that specific frequency. Once you have your best voltages then test globally with heavy usage, such as gaming, gps and phone calls all at the same time. Once you find the a sweet spot then you can increase the voltage by a notch to ensure stability. This could take a long time, just may sure to not click on set values on start up unless you are sure of the stability.
