just because yours can, doesnt mean that everyone elses can. and lowering the 384mhz steps voltage below 750mV can and will bring you issues, even though you wont know its caused by lowered voltage, like signal drops. most trinity users dont care as much about lowered voltages, as the battery life on trinity is just as good with or without lowering voltage.
[Nexus 4 Original Android Development] jonup:
What's the lowest voltage (equivalent to 750) for hh? I've been using 775 for a while and just lowered it to 765 wo an issue.

the lowest i tried on the nexus 5 is 725mV at 300mhz. but that was a while back, just to try it. i dont undervolt at all.
[Nexus 4 Original Android Development] albundy2010:
I wish DVFS was done in HW where it belongs and this entire undervolting crap would be away altogether,

Then overlocking / overvolting would too but I dont care. They was its done now on arm chips is just stupid.

I would love to see how much of a difference it would make on the current crop of SoC"s to be honest.

Once day Intel will eventually show the ARM armature hr how it should be done. There is a chance that nvidia might be able to do it too but I doubt it. The are too desperate for design wins to be able to lay the law down and do it right.

[Nexus 4 Original Android Development] jonup:
By default yes! Then again, you should be stuck at min freq when playing music. 2 vs 4 cores at min freq equals negligible difference in power consumption.

Is anyone else having problems with their Google account syncing lately? It's been giving me an error for the past few days on my phone and nexus 7. If I manually sync stuff it works just fine but I still have an error and I think it might be hurting my battery life.

Your wish might come soon. Rumormill about a week ago said Intel might have won the bid for the next N7 SoC.
[Nexus 4 Original Android Development] FuPete:
Please not. Stock Voltages are far too high. I dont want them to be fixed.

I would appreciate it if the kernel could go lower than 750mv. For those who have problems with it, they can easily fix it in their Kernel-App.

Using Faux atm with 687.5mv, and everything is fine. Battery life ist very good.
[Nexus 4 Original Android Development] jonup:
What's the real life battery life difference between 750mv and 687.5? Or you just want to less voltage for sake of having smaller than mine. ;)
[Nexus 4 Original Android Development] hypemanisus:
i saw trinity four branches have been updated today. may be that means something
[Nexus 4 Original Android Development] FuPete:
In fact it's 16% less power consumption when in idle (because it is V²). Im just trying to optimize my phone as good as possible :good:

My phone isn't that good to undervolt, I'm sure there are people who can reach much lower voltages ;)
[Nexus 4 Original Android Development] stark_br:
Realy?

I just saw 2013 in there.... :(
[Nexus 4 Original Android Development] simms22:
16% less power consumption says nothing, its theory. what is your actual battery life like, whats your screen on time?
[Nexus 4 Original Android Development] jonup:
Well that is V² not 2*V so it is like 17.5%. But we all know the formula and we can all do the math. What I asked you is whether you can actually measure real world difference. i.e lock the frequency at 384, and run the phone once at 687.5mv and once at 750mv. Report if you notice any difference. Even better run 384@687mv with faux and 384@750mv with Trinity. I am a bit prejudice, but I can only guess the results. I've ran lower V on other kernels. At a certain point reduction in V returns marginal results if any. This is why Morfic doesn't implement 192mhz and <750v. They add nothing to battery life but create buzz for other kernel. This is bs free kernel.

I thought the diference would be greater than it showed up...
[Nexus 4 Original Android Development] slaid480:
Nope,the quad version is a normal A15 CPU like the one on the Tegra 4(besides the big GPU revolution),that's why benchmarks are close to Tegra 4 specially on CPU side.

The dual 64Bits would be faster with ARMv8.
[Nexus 4 Original Android Development] simms22:
right.

which is why we are saying that lowering the voltage at that step is pointless.

the problem is that many are hoping for miracles when it comes to their battery life, and there are devs out there that keep the myth going.

And the majority of them (if not all) charge their phone several times a day so they don't actually need all that paranoia.

[Nexus 4 Original Android Development] albundy2010:
Irrelevant

Stock voltages are currently controlled by software. When done in hw it is not that way. Instead of four cpu bins like the nexus 4 with predetermined values for each, hw can have much more and actually provide the right amount for basically any chip.

Doing voltage in software is dumb. Doing clocks is dumb. Cpufreq period is dumb.

This is not about some nerds on xda adjusting voltage with apps or setting them in the source. It's about the fundamental design being flat out stupid. Wasting cpu cyles to do DVFS is just dumb.

You will get a far better experience both user and battery if this crap was done in hw than in software too.

Even the idea that one would have to get a custom kernel, and a app to change the voltage,, hotplugging etc. That alone shows you just how stupid it is doing it in software.
[Nexus 4 Original Android Development] Detailed:
What about heat? Doesn't undervolting help with heat especially for our phones? That's the main reason I undervolt. Battery life increases are not noticeable from what I've experienced. Also, sorry for this OT question that is upcoming, but does anyone get Artifacts from playing GTA 5 @ 487mhz on the GPU? (I'm using TF11 4.3 with DePRIMA) Do you think it's cause I need more voltage for the GPU? Or is it just the game?

[Nexus 4 Original Android Development] FuPete:
This Thread is in the Nexus S section. Quad core phones need much more power. When at home and wifi on, I get about 5h SOT and 24h with battery (with automatic brightness), but I also can fully discharge my phone in 2h, when playing GTA:SA with high clocks.

Undervolting definately helps at high clocks, to prevent thermal throttling. And you also save a lot of energy. -175mv is no problem for many Nexus 4's.

And everyone who overclocks his computer knows, that 175mv is a lot for a CPU.

I agree with you when you say, voltages under 750 wouldnt save much energy. At low clocks the power consumption of the CPU is very low. But why not optimizing your phone as good as you can? It is fun for me.

I never experienced issues because of low voltages on all of my last 4 smartphones.

Anyway, this is a great kernel. At the moment I use faux because of higher OC, and because there is no newer trinity version ;)
[Nexus 4 Original Android Development] albundy2010:
Quad core phones don't need much more power.

It is actually one of the least important factors. More important is the process node, the cpu architecture itself, along with entire SoC arch ( gpu and all the rest) how high they clock the chip and how much leakage you get at those clocks.

I am not a fan of quad core in a phone either. Not a fan of anything these SoC vendors have been doing actually. But they don't use much more power. And it's just a bad way of putting it. You could make a single core A15 SoC and use more power than a quad. Other things are more important than core count.
[Nexus 4 Original Android Development] FuPete:
They don't do in idle, but they definitely do at full load.

I never saw a spreadsheet about how much power the cpu needs (though it would be interesting) . But I'm pretty sure that the tdp is much higher than that of other phones.

On my previous phones I couldn't feel the heat like I can with my nexus 4. Except my Sensation, which was a bit warm when playing games

The nexus 4 gets really hot at full load, which is a indicator for a high tdp.

High tdp = high power consumption :)
[Nexus 4 Original Android Development] albundy2010:
That is just all wrong.

Your feel means absolutely nothing. Different materials will give off different feelings of temps.

So your feeling has absolutely no bearing what so ever on the TDP

The dual core chip in the nexus 10 can actually draw up to 8 watts before it realizes that and that it won't go past 4w

The SoC in the 4 is no different than any other s4 pro ( I don't want to type all the exact chip names and known the s4 pro badge is useless. If anything it actually runs cooler than the other devices SoC wise. Since the battery temp throttle will kick in and lower the clocks. While other devices don't do that as soon the SoC will actuality get warmer.

But oh I don't feel it. Again feel don't mean crap. Let's take two very popular phones over the last year. The HTC one and Qualcomm version gs4. Now we should know the s4 has a higher clocked / binned version of the same chip in the HTC device. Run the same workloads and see what feels hotter. The metal phone will. Even though the SoC doesn't have a higher TDP and doesn't even need to actually warmer than the gs4.

All modern high end devices essentially have the same TDP. What is different is the form factors and how they deal with heat. In larger devices like tablets you have more area to dissipate the heat. So the chip runs at what is really it's boost frequency longer.

In order devices that were single core, they were also pushed to that max. If you had a device like the nexus one you be surprised at just hot that got. The iPhone 3gs even had a issue were it would get so hot that it discolored on some units. Apple issued a update make it throttle sooner.

If Simms22 seen your post he probably already replied while I'm typing this. But your feel is completely irrelevant to how hot the cpu is and even more so to the TDP

---------- Post added at 09:35 AM ---------- Previous post was at 09:11 AM ----------

Edit. Keep in mind depending on who you ask, TDP can also mean different things. A look into the AMD Intel TDP crap from a years ago is the prime example.
[Nexus 4 Original Android Development] FuPete:
It makes no sense to discuss this here, unless someone got a official spreadsheet or something.

Anyway, I am convinced about the positive aspects of UV, especially at high clocks.

There is no doubt that it saves battery and helps to prevent throttling.
[Nexus 4 Original Android Development] jonup:
Man this is Trinity thread - discuss away. We all have something to gain from a discussion. There is no doubt that voltage has an effect on tpd and power consumption but it has limitations to how much lowering the voltage helps on certain scenarios.

To begin with, I liked this Kernel the most, trying on hells-core and something feels off.

And then, I liked this thread because I see albundy a lot. (as well as learn stuff, since albundy's info is sometime faster(and probably more accurate?) than mainstream media. (like that gsmarena that loved to bias on the S(uck) brand. I hate their smartphone product line for a reason. )

GO TEAM BUNDY!
[Nexus 4 Original Android Development] jonup:
So it's not just me gsmarena is all over the S(uck).

I don't always agree with Bundy but it is a fortune having him here. His "in odds with the mainstream" attitude creates thoughtful discussions. As long as people understand that this is only discussion and they should not get offended, like some in the past, the community is much better off after one of his rants.
[Nexus 4 Original Android Development] stark_br:
+1 to not always agree with Bundy, but his last arguments are quite good in every away.

Why you guys dont like gsm arena? Sorry, but I did not understand....
[Nexus 4 Original Android Development] jonup:
It's not that I don't like gsmarena, I do, but their comparisons are always biased towards Samsung. I.e. note 3 vs 1520. There are 2 things that go note's way -size and being android. In person 1520 made me jealous. They made note 3 walk all over 1520. Another one, HTC One was the first phone that made Anand move away from iOS, and it was mostly the camera. Gsmarena concluded that S4 camera was better than One's. They also promote Samsung's bloat, no matter how useless PR shït it is. It's not that I don't like them, I just sometimes come up with different conclusions than them looking at the same data. Maybe it's my fault.
[Nexus 4 Original Android Development] KiD3991:
Well, in such topics a person can't be always accurate in the subject, and then there are also personal preferences, like the previous topic UV, I only do it to keep my phone cold(I don't like a hot phone and it might be a light trauma since my LGO4X era), and I underclock, so my phone is chilly most of the time(I get face freeze working at the mall if I pick up phonecalls). So its a personal preference.

GSMarena is one of the best place to check out information for a lot of phone models since its up to date, but if you look through their reviews, they are always biased towards the S(uck)amsung brand, in a lot of things, such as speed, camera(ESPECIALLY CAMERA), and even bloatwares like Jonup said.

Yes and no. Its not you, GSMarena is a bad reviewer, and probably paid to do so. If you look at their video and camera comparisons its extremely obvious they are biased towards Samsung. And they didn't even put in that one of the only reasons Samsung Phone Camera's picture looks better is that they are viewed in AMOLED.

I once worked in a camera that develops photo, 9/10 Samsung phone camera users complain about the outcome, especially the contrast and sharpness (and solidness?) of their photos. Our shop did colour enhancement(by hand), and its useless, with colour enhancement the pictures looked like it was taken by a camera which a 5 year old messed up all the settings.

On other hand, look at their big comparisons, all the results mostly have Samsung standing on top. Or have Samsung always within top and second so that it looked more "balanced".
[Nexus 4 Original Android Development] stark_br:
You both are rigth about gsmarena and samsung, it was my fault no to pay attention to that particulary detail (they use samsung too much).

As jonup said, Nokia 1510 nothing but great and they managed to make GN3, with all that samsung bloat, a better device.

[Nexus 4 Original Android Development] albundy2010:
I don't own one and only used one for 5 mins. Hard to do that based on that.

But some cons I see are not really unique to it but apply to the entire nexus line and play editions software wise and hw wise just industry trends really.

Software issues. It runs Google camera app and that is the biggest pile of crap there is. Then the launcher thing. I dont like the fact that its a nexus 5 thing only officially. I think that's stupid.

Hardware is a bit different. I dont like trend of making devices slimmer and slimmer, Add some bulk back and use a bigger battery. But thats more complicated with a device like %. Some if for design while some is made for cost. It is kind of disappointing that they did not use many of things the hw platform has to offer. Like screen off voice and camera crap. 1080p @ 30fps max on that platform....like come on man. And I don't like the design

The good, well everything that makes a nexus good. Plus a good screen, the radio platform /bands plus envelope tracking.

So mainly I like the phone, but like any device there is some annoyances for me. Like the protruding camera hump that I forget to mention.

Edit. I also like to look at things different that most on here. I see it from how I would use the device myself AND the out of box experience /default/stock/googles vision/ the shipping product or however you want to call it. They are mainstream consumer devices. On display in mall shops / best buy etc. That matters more now then ever.before with unlocked / no contract catching on more and more.

Nexus 5 camera being a bummer for most people is due to the fact that the device is provided at a price lesser to the its original variant LG G2.
