This is the problem not that you have dual cores on a mobile, but the fact that battery live would be severy shortened, with that said new tegras I heard on the grapevine that they will be able to switch cores off that are not needed, so in case you need a second core then it kicks in....

Buts of course theres a but, I read this in a article where they mention this for Tablets and tegra3 quad core cpus...

Im pretty sure similar tech would be used on a phone otherwise you require a 6000mah battery taht would prolly be as long as the whole phone... lol

Dual-Core processors will help with that very extreme case of running a Playstation Emulator on a device connected through HDMI or streaming 1080P, but this is something that the masses won't do. Battery life seems to be the issue that is more important, and with the implementation of LTE this is looking like a bit of a problem. If you take a look at Verizon, you will notice that for some reason they haven't successfully paired the two as of yet.

Thunderbolt = LTE but no Dual-Core

Droid Charge= LTE but no Dual-Core (really good battery life by the way)

Moto Droidx2= No LTE but has a Dual-Core

Hopefully this will change in time but I feel it has to do with battery life being affected when combining the two. If there was somehow a way to poll the masses that own a smartphone I guarantee if gave them the choice of either having a faster device or better battery life they will choose the later.
[General Topics] vbetts:
The LTE radio might drain battery, but as it's been said before dual core setups are made to have about as much power draw as a single core, that plus the dye size and total tdp. That being said though, I wouldn't mind a better battery life.
[General Topics] wattnxt:
Does anyone else remember this arguement regarding higher clock speeds in smartphones, extra RAM for PCs, stepping PC dual core PC CPUs, etc...

It has and will continue to to proven that stepping up the processors for bursts gives us better battery life and MUCH faster response (remember how annoying lag is) than using a low Hz processor and let it churn away longer.

Combine that with only powering them up fully when needed, and one processor can close out your existing app, while the other opens up the next app at the same time. Same computations, half the time. Same battery consumption either way.

If you use your phone the same way, and power management is written properly, a dual core will give you better battery life AND smooth, fast response. IF; however, you use your newfound speed to run twice as much at one time the opposite will be true but that's not the fault of the dual cpu.

Remember the days when PC salesmen would say that you'll never use a dual core processor, or that dual cpus would make your laptop battery dead in 20 minutes? Not the case, and the batteries have gotten smaller.

Processing power doubles roughly every 15 months, moreso with phones. Going dual processor uses far less energy than a single 2 Ghz processor when used and managed properly, and is more fluid.

I, for one, look forward to tri and quad core phones. Imagine your launcher with a dedicated cpu...zero lag, uber smooth, and cpu throttled to min when screen off...you get the idea.

I'm all for duals and beyond...my 2c.

Now if only HTC could read my mind about unlocking the Inc2...

Well if you compare an old 3 ghz single core like a Pentium 4 that was I think 85-95nm to an i7 that's 32nm, easily the i7 uses less power due to the huge difference in dye size. But then look at current single core cpus now, single core celerons use 35w at 65nm, and 45nm Semprons use 45w. Dual cores and quad cores use almost near double, but it's still a lot less more heat and power compared to older single cores.
[General Topics] Haplodroid:
It is true that a more advanced multi core cpu can use less power than an older single core cpu. For reasons like it's smaller, can dynamically use less than all cores, and other advanced technology.

Performance wise, I don't think we'll see many multi threaded apps soon, however, big ones like browsers should see multi threaded versions soon.

I disagree, sorry.

Last PC I built 6 yeas ago had 2 gig of ram and everyone asked me why I wanted that much but it lasted me till last year.......so my present PC has quad core (8 with hyperthreading iirc) and 12 gig of ram......that should last a while.

In the same vein, my last phone was a Tosh TG01 (with the 1 gig snapdragon cpu) and that phone lasted me very well for over two years taking all the software I threw at it and running it silky smooth.

Now I'm on the Samsung Galaxy 2 which I know WILL last me till my two year contract is out because it's overkill at THIS point in time.

dual core versus single core

I have a my touch 4g and my brother just bought a G2x.My phone is rooted and if I overclock

it to 1800 ghz my benchmark final number scores are about the same as the G2x scores unrooted.The my touch processor seems to bottle neck when it gets in the graphics part of the benchmark test.The G2x graphics scores are almost triple of the my touch phone.I'm really happy with the my touch 4g but my next phone will be a dual core both phone's cost about the same price.We rooted the G2x and flashed the CyanogenMod 7 rom that phone is off the hook I believe two cores are better then one.
[General Topics] PlasticChicken:
Same thing happened to me except I'm the one with the g2x. I'm a true beleiver for dual cores on my phone now.

I can see where the op is talking about but I think he's making the wrong comparison. Overkill would be the i7 six cores with 16GB of ram. I can Max out my Quad core i7 with 8gb ram and a 580 gtx quite easily. The g2x is a vast improvement over the single core phones. Just try one out and you'll realize how sluggish your phone is.

After buying my first Android phone a week ago, i feel the battery usage is a bit depressing coming from a Nokia symbian device. My phone is a 1ghz LG and it's plenty fast and snappy, but even with a 1500mah battery, i don't see much more then 2 days of light use.

So for me, a light to average user, i'd hate to have a dual core device that eats even more battery then what i have now.

Dual cores..

Lets start by saying I am no expert on anything but please if I am wrong let me know and if I am right back me up with facts.

As I remember I have had dual cores for a while, just call it "specialized" cores.

remember your graphic card with the independent processor even before we had our multi core processors.

Well our advance communication (smart phones sounds wrong to me now day) devices don't have the luxury or room to have those independent processors, so that work rest on the processor. I like my hd video, I want the 3d enhanced graphics.

Also correct me if I am wrong but having dual core reduces heat, due to the ability to turn task to one processor or the other, and even more when it comes if one processor can turn off and on as needed. Heat is the number 1 enemy for microchips so less heat = better performance.

Last I do not like to carry a lap top my phone is my laptop I am just waiting for a greater integration with peripherals which I know is coming and I will be happy. GO GO 4 core, 6 8.

And yes batteries in my point of view are one of the biggest barriers for many technologies from my point of view.

Edit: ohh yes also to rub it on ihpone users face

I think dual core is really good improvment. But im afraid of battery life.
[General Topics] PharmCAT:
Overkill for now maybe, but when it becomes the minimum standard, like the Core2Duo for computers, then I think we will truly see most of the benefit. Simply put, we need the iPhone 5 to include a dual core processor, not because it's an iPhone, but because they can effectively push the demand for for dual-core processors to be put on android and as a result pricing will become more competitive.

As of right now dual-cores phones are still a luxury.

Well, actually, I think more smaller cores would be an effective way of battery saving and temperature reduction. If the phone needs power, it uses all the cores spreading and sharing the charge not overcharging one single core; if the phone is on standby it only needs one of those small cores having essentials on.

[General Topics] kthung:
Here's what I think. I don't think that the OP was trying to state that we should stop developing next gen processors, but that this shouldn't be the biggest focus for smartphone development and marketing. With this, I AGREE ENTIRELY. Many people already stated this earlier, but I feel like the biggest hindrance to smartphones on the market today is battery life. Current smartphone processors are PLENTY fast, so how about we try and make the next processor just as fast but maybe cut the power consumption in half?

I kind of equate the smartphone market to the high-end digital camera market (scratch that, make it any digital camera market). All of the biggest camera companies have been participating in the "megapixel race" for several years now. Each year, trying to cram more and more pixels into the same size (tiny) sensor. While this sounds all well and good on paper, in practice having such high pixel density actually degrades picture quality, especially for low-light photography. But each year without fail, consumers just pick up the camera with the most megapixels thinking it will take the best photographs so the camera companies continue to follow this trend. In this sense, smartphones are similar where most consumers just look at processor specs and pick their phones based on that. Seriously how often do you see battery capacities listed in ads? I think if consumers were more educated (Im talking general populace, not xda :P) then companies will start making phones that perform better and are more practical. just my $.02

Unfortunately, multi-cores make it easy for developers to continue to be sloppy, lazy, and inefficient. I am not against progress... but I think for now we would be better served with more cores AND / OR higher speed with less power consumption.

Guys,let's face it,we don't buy expensive smartphones to have a better battery life than the typical dumbphone.And it's not processors that are the main cause of battery drain.Hell,it's not even the second cause.The biggest battery drainer is the big screens these phones carry.Combine that with baseband radios etc,the CPUs get a third or fourth place in battery consumption.

Don't get me wrong,processors can play a part in bettering battery lives of our devices.Bigger(meaning with better tech,not larger in dimensions) batteries with capacities comparable to those of today's laptops would suffice I think... :cool:

I don't really see the difference between dual core and single (having used both). The only difference is that sometimes (rarely though), the web pages appear faster. IMO, having a dual core processor isn't the only thing that would win me over in a device.
[General Topics] vbetts:
If the app is multithreaded, then there will be a performance gain and the app should be able to handle more and retain its smoothness as well. Dual cores most likely seeing the pricing are about a little bit more to manufacture than a single core these days, but this could easily change as smaller dye sizes come.
[General Topics] wtfnoob:
is,NT the point of "dual core" about less strain on the device, less heat, less battery power, all while running more apps like HD video games whilst still receiving email texts phone calls etc, 1 core running full speed at 1ghz will produce more heat and strain than 2 cores running at 528mhz each, someone please quote me if I'm wrong.

[General Topics] TheDub:
That would be correct. However Android doesn't properly utilize these two cores at this time, at least not efficiently. Applications will not benefit from dual core unless they are written to do so. They need to be multi-threaded. If they are not then it won't split the load up to 528mhz per core. It will do Core 1 with 100% load and Core 2 will sit Idle.

Same goes for the Operating System, if it doesn't know how to properly handle that other core it will not be utilized efficiently. In some cases performance can actually suffer from using a Dual Core processor in an environment that doesn't know how to handle it.

It took a while before Dual Cores in the x86 world outperformed their Single core siblings in real world usage... once Windows and applications started handling it more effectively only then did it start to run circles around Single Core.

It's overkill now, it might be for quite some time, but eventually it will be the standard and utilized properly.

The real question is when will Android and Applications evolve to a point of actually needing that much power...
[General Topics] vbetts:
The actual OS does not technically need to be multi core optimized, it just at least needs to see the two or multiple cores there. Now if the OS is optimized for multiple core, it will give better allocation to apps that are only single threaded. Hopefully HTC, Samsung, Motorola, and LG all have written some type of multithread optimization for Android. That, or at least for Tegra 2 devices, Nvidia has sources for an Androidy ready multi core optimization.

The big problem with first gen dual cores is they weren't real dual cores. Netburst cores stacked on top of each other, so apps that did have some kind of multithreaded support on Pentium D's were not that much faster, and Netburst was terrible.

[General Topics] sony3127:
Dual-core processors in both PC's and smart phones are absolutely worth it. They certainly improve the device's ability to handle multiple threads (even if the specific app isn't made for multi-threading) because the OS alone uses processing power, then of course there are the background apps, and of course whatever it is that you are running. There most certainly is a noticeable difference for power users. (and the typical "power user" is becoming more and more common) I have worked in IT for 11 years now and my Samsung Epic is the BEST piece of technology that I have owned to date. It is incredibly capable and useful! However, I just got a Galaxy Tab 10.1 and the dual cores in it have noticeable impact on multi-tasking; which I do quite often. I'm downloading things, while opening other apps, and saving things, copying from one app, going to home screen, and then pasting in other apps without closing the original, all while playing music, ect. IT'S FANTASTIC. No, it's not perfect, but dam it's fun! Now quad-cores, those start to be come questionable for me...

The argument isn't whether or not dual core is faster, we all agree it is on paper. The main argument I see is do phones, or more specifically android demand enough power to utilize it at this time?

But back on topic, I have an X and an X2. I can hardly tell a difference between the two.

So, I don't think these extra cores are needed. They might be nice to have, and I would take a dual over a single, but it really doesn't matter to me.

Well I'm using the ROM of which you've listed in the second link. Here are some tips and see if they help:

1. Make sure you have the latest SE firmware (2.1.1.A.0.6 and baseband version: 53404015) Do this by checking software updates with SEUS (Sony Ericsson Update Service)

2. Ensure you've got the right Xrecovery version. Download and unpack and flash THE ONE BUILT FOR THE MINI PRO or else some features in xrecovery may not work or even brick your device.

3.Remember to wipe Dalvik Cache and do a factory reset in xrecovery BEFORE you install any of these ROMs.

4. You may also wipe battery stats before you install the ROM, but I don't think this is essential.

The install should be flawless if you follow every of the steps listed by the devs who developed the ROM, and take these steps above only as an advice...I'm not responsable for bricking your lovely phone...
