To get back on to the topic of CM10, I'm starting to see an improvement in battery life as the builds get closer and closer to completion. I went a little over a day with about 3 hours of screen on time and I still have 20% battery. I had at least an hour of 720p video streaming through Crunchyroll as part of that screen on time.

[Samsung Galaxy SL i9003] mowilfred:
My i9003 was half bricked!!!

So what I did was trying the root the phone by flashing ZHKPE-CFROOT-25-05-2012.tar through odin but it didn't go though and got stuck half way and I can't reboot the phone. So I tried to flash back to the ZHKPE stock rom using odin, but again it got stucked in Odin on system.rfs. Been trying for a few times but it's still stuck. So all I got now is the bricked screen, I can still get into download mode, so I was wondering if there is anyway I can revive my i9003.

PLEASE HELP someone!!!!
[Samsung Galaxy SL i9003] Rentaghost:
Ok.

Flash xxkpe with pit .

Then flash ZHKPE.

Then wipe and wipe cache through recovery.

Then you are good 2 go !!!

What is the difference in battery lifetime between the dual core and quad core versions of the S3? I currently have a quad core S3 right now. Would it be wiser if I sell the quad and get a dual core from the US instead?
[Galaxy S III Q&A, Help & Troubleshooting] kulisap:
what about keeping the quad-core and buy an extended battery if you worry about the battery life? ;)

Mugen do a 2300mah battery that fits the S3 with working NFC for £30

Selling a quad core to buy a dual core is a dumb idea
[Galaxy S III Q&A, Help & Troubleshooting] d4fseeker:
First off: note that there are lots of different versions with the same "S3" name, most of which probably are not and never will be compatible to your current carrier's network.

The i9300 uses hotplug technology to completely shut down cores when their processing power is not needed and re-awake them whenever you open a CPU-intensive application. So in the bottom line it does not drain more battery unless you actually need more power than the other one can deliver.
[Galaxy S III Q&A, Help & Troubleshooting] sebarkh:
It doesn't have to be CPU intensive application, it can be a normal application that will use all cores, each at not maximum frequency.

The only thing I like about the dual core versions is that they come with 2GB of ram, which should be standard for a Top End phone, specially with the amount of software that Samsung puts on their phones.

Of course, I know the dual cores are Cortex 15 which is a newer core but I don't value that as much as I do the 2GB ram.

Other than that, I'm really happy with my SGS 3 (international version, unlocked)

[Galaxy S III Q&A, Help & Troubleshooting] kevindd992002:
So you're saying that the quad-core is as good as the dual core in terms of battery lifetime?

But I thought all S3's are compatible for all 2G/3G networks around the world?
[Galaxy S III Q&A, Help & Troubleshooting] Edward Zhuang:
dual core has a longer battery life
[Galaxy S III Q&A, Help & Troubleshooting] Arsaw:
Not necessarily. Everyone is using their phone differently. Every battery produced in factory is also not 100% identical. So basically no point trying to compare between dual or quad.
[Galaxy S III Q&A, Help & Troubleshooting] MasterTB:
No, I'm saying that what I like most about the dual cores is the 2GB of ram they come with. I'm comfortable with the battery life of my quad so I don't complain about it, and don't even wonder about what the duals can do.

I had a SGS 2 (still do) and even with the pumped processor (and slightly bigger battery) this one still lasts more that a day of relatively heavy use so battery life is not a problem. Maybe the new duals cortex A15 have better battery life than this quads, maybe not so much BUT, they're not quads :laugh: and that was a good selling point (for me).

If Samsung had put the same 2GB of ram on the quads (like they did for the Korean version -envy-) then no one would want a dual, and no one would complain about battery life -or even wonder about it-, but they didn't.

If you ask me, the best phone to come will have 2GB ram (LG has announced already and Xiaomi too with the Mi2 coming October), then our quad SGS 3 will come short, that's my only complaint.
[Galaxy S III Q&A, Help & Troubleshooting] xTristinx:
Also to the point where the dual core has lte which destroys your battery. :D
[Galaxy S III Q&A, Help & Troubleshooting] crnkoj:
The dualcore one uses a qualcoomm krait cpu which is based upon cortex a15 unlike the quad exynos which is based upon the cortex a9 cores. The a15 architecture is by design depending on the task to do up to more than 100% faster as compared to the a9 in single core and single threaded tasks. So speed wise they are quite equal, while the exynos has a better gpu, the krait is made in 28nm, while the exynos is made in 32nm, so to make the story short: in theory the dualcore should be as fast as the quad, while using less power, assuming both have the same battery, the dual should last longer in theory, but i havent seen any thorough comparison tests of it until now.
[Galaxy S III Q&A, Help & Troubleshooting] MasterTB:
In theory is the most important thing here. And, for every app that can use all 4 cores the quad will have the upper hand. I've seen the reviews and the SGS III still manages to beat the duals (A15) in general performance tests.

That's why the new top dogs will use 4 Cortex A15, and 2GB ram configurations, those will be unbeatable.

Still, LTE on the duals will kill all battery life differences.
[Galaxy S III Q&A, Help & Troubleshooting] kulisap:
I disagree. 2 cores process a task longer--longer time=longer battery usage. Shorter time for 4 cores--4 cores=high battery usage. Am i making sense?

[Galaxy S III Q&A, Help & Troubleshooting] nodstuff:
Wrong.

The krait is not pure a-15.

The exynos is not pure a-9.

If anything the both meet somewhere in the middle, the exynos is built on a smaller die than standard a-9's and a 128bit instruction set (a-15) and is fabricated using HKMG process (reduces power leakage by up to 50% if my memory serves me right)

The krait is still using the older, less efficient Lsion process and is nowhere near as good as HKMG.

Samsung have tweaked the sh*t out of the exynos 4412 and it has been around for a while, the krait is new tech, not nearly as much time to optimise it.

Now another point is that development on the US version is nowhere near the level of development for the international and has a lesser GPU and DAC.

I wouldn't trade for anything.

Well in saying that I'd like 2gb of ram, but with this SOC.
[Galaxy S III Q&A, Help & Troubleshooting] LiquidNarwhal:
*facepalm* I don't know how many people I've tried to tell this the I own both the dual and quad. the 2gb of RAM literally has zero effect on the end user experience, the quad core is much more zippy and has the better GPU. 1gb of RAM is plenty (same redraws exist on the 2gb, no difference in multi tasking)
[Galaxy S III Q&A, Help & Troubleshooting] AndreiLux:
The Exynos is pure A9, that 128bit instruction set claim floating around is bull**** and the only true thing that may have come from is that the internal bus might be 128bit wide, that's all.

Si-On is indeed worse off than HKMG and that is the main power advantage of the Exynos.

In the end without going into the technicalities for the n'th time, they are equal in battery life and none of them has the advantage. Peak load (All CPU cores 100%), both deplete in almost identical time. The Exynos is more friendly on light loads due to its manufacturing process, the Krait is more efficient in medium loads due to the architecture.

RAM is truly the only thing disparaging the two, and of course the rest of the on-device components. The Mali is still faster of course, even if it's showing it's age on polgyon heavy loads, but there's no real game out now except benchmarks which actually bring it down for the moment.
[Galaxy S III Q&A, Help & Troubleshooting] racerex:
Qualcomm's Krait cores are more advanced than the Exynos4 Cortex A9 cores. So for a given task the Krait cores will consume less energy. Yes the Exynos 4412 has a more powerful GPU but unless you're a harcore gamer I'd rather take the GS3 with more RAM because it's a better multi-tasker. The writing is on the wall as all the latest flagships using both Samsung and Qualcomm are shipping with 2GB of RAM...

I'm going to go ahead and defend Nodstuff on this one, he's correct about it not being pure a9, also as much as anyone will tell you they have the same processing power, I've found the user experience on the quad core significantly smoother, and no it's not a placebo I've done a direct comparison several times. Again the RAM has zero effect on the user experience in this case, stop acting like 2gb is the savior of all humanity inferior processor and GPU with 2gb of RAM doesn't solve anything. anyway hope this helped. :highfive:

[Galaxy S III Q&A, Help & Troubleshooting] AndreiLux:
How can you claim it's not a pure A9 just on user experience, that's the best definition of placebo and misinformation ever. The cores are instructionally identical to any other equivalent A9 chip.

The user experience has absolutely nothing to do with the CPU and even the S2 can do scrolling around through menus, I can cook you up a kernel and you will find it the most smooth and amazing experience ever yet it doesn't mean crap about how much of that actually comes because you have a faster device or because it it set up to be faster. The majority of the time the fourth core isn't even online so the argument that the quad cores bring a benefit is nonsense. That all doesn't mean squat though, it just means the S3 has a more smooth experience due to drivers and power scaling.
[Galaxy S III Q&A, Help & Troubleshooting] nodstuff:
Well you're the developer here so I'll take your word for it! :)

where did all of this talk of 128bit instruction set come from?

I did a bit of searching on Google to see if I could find the whitepaper for the 4412 but all I could find was articles saying it had a 128bit instruction set and as we all know online media outlets aren't exactly reliable, all it takes is one person to print that it has the 128bit instruction set and next thing they all run with that story.

If you don't mind me asking, where did you find out that it has 64 (presumably) instead of 128bit?

And yes I should have put in my post that both are the same battery wise at the end of the day, I was getting on a train and and my article got cut short! :D
[Galaxy S III Q&A, Help & Troubleshooting] AndreiLux:
You hit the nail on the head on that one, it was a single bull**** article from back in February taking some value out of context and then everybody started repeating it. I realized how retarded most of these websites are and almost none actually bother to check what they are writing and just regurgitate nonsense on a conveyor belt, I noticed this when all except a single website were talking about the GPU clocks and pissing values left and right repeating rumours from the forums, and yet only a single one (I forgot which one it was now) actually bothered to even Google it and actually found my own personal research which I posted on Beyond3D back last winter.

As for the instruction set, it makes absolutely no sense what-so-ever for it to have 128bit. And again, since people love throwing numbers around, this is supposed to be the SIMD width of the NEON units, which are in the Cortex A9's by default 64bit wide, again, something which has absolutely no effect on performance outside of video encoding and decoding on software, which is irrelevant in most uses as we're using the dedicated hardware unit. The 128bit bus is also somewhat confirmed by the fact that the internal bus frequencies are halved compared to the 4210, so they very well might have doubled the bus width to decrease the frequency, which in turn decreases power usage for the same memory bandwidth.
[Galaxy S III Q&A, Help & Troubleshooting] speedyjay:
Yawn!!!
[Galaxy S III Q&A, Help & Troubleshooting] nodstuff:
Ah so it was all a case of Chinese whispers!

Forgive my ignorance here but when you say the bus frequencies have been halved, but the width doubled, does that mean there is room to OC them?

Isn't that usually a bottleneck?

Would there be much to gain from OC'ing the bus?

I didn't mean to imply it was due to the actual cpu/gpu that the user experience was better albeit they are better. I'm just simply trying to say those who want to switch to the stateside version are mislead and misinformed that the 2gb of RAM makes a difference in overall usability, and end experience. In the end you are correct drivers are key, and seeing as how Exynos is Samsung's baby it will almost always be a slightly more smooth experience at least IMO. sorry again, if I seem out of line, I just word my statements poorly when I'm in a rush.

Interesting stuffs... i noticed too that the web is a conveyer belt of nonsense... i would love to one around on the Weiss for a couple weeks to see the difference... Korea seems to be the big winner here. One thing i notice and am curious about is when i am using my phone and sometimes i check the RAM it is close to a gig constantly. I wonder why that is, would a phone with 1g memory use this much to function also? Just because i have 2 gig memory does it use half of it for s#its and giggles? I came from an incredible with 512mb and ran the same software and it used less memory.. does the quad constantly use 859mb or so of ram like the dual? Please tell me if i make no sense... i find my battery life on the sch-i535 to be exceptional. And even more so after i unlocked my bootloader and tinkered with the kernel a bit... very interesting stuff y'all i will stay glued to this discussion as i poke around.

Well, quad cores split work using lower frequencies and save battery. Dual cores have to use higher frequencies to do the same work so they eat more. But quad cores have to feed 4 cores and dual only two... Also architectures influde but both have modified efficiency-oriented processors. Well I prefer exynos for graphics but the diference is not too remarkable.

You know what? I think in the end it all depends on what you use your phone for and the configuration you set up for your CPU and kernel but there's no true winner here.

The thing that does indeed make the difference IMO is ram. I've seen my launcher reboot after surfing the web with google chrome for a while due to memory shortage several times. 1GB will be insufficient soon if apps continue growing. Also we are having more and more services running in our devices and android is going to be bigger over time. I'm sure international S3 (which I own) will become obsolete sooner than US versión.

Important only to those that use Skype and are counting on that call to get through as opposed to making arrangements for certain time and launching app few minutes earlier and keeping app in foreground.

[Galaxy S III Q&A, Help & Troubleshooting] ArmorD:
There's not much difference in battery life because SGS3(just like any other quad core device) doesn't use all cores at the same time. It probably only uses two, and when you're in need of more torque, the two other cores will step in. However, if you have a kernel that supports some kinda tweaking app(I have SGS2 but I think there's ExTweaks for SGS3 too) you can disable cores and only use two if you like.

From that article one can see the tech specs and the performace (sadly it only compares to the sgs2 exynos but single core the sgs3 shouldn't be any faster than that). And than in term of someone elses logic here, the krait cpu can run at lower speeds and volts as its twice as powerful -> lowered power consumption. That said both come to a very similar end result.

"longer battery usage" vs "higher battery usage"? Not sure what you're trying to say.

According to an earlier poster, not only [on a per-core basis] is the dual core's design more advanced (more powerful) but it's also more efficient / produced using a lower power 28 nm chip fab process.

The quad-core does appear to be more powerful on most benchmarks I've seen though, so if you're willing to give up a little battery life for more performance go with the quad.

But, I would certainly not sell the quad to buy a dual if I already had it. I would instead put a custom kernel and tweak it for better battery life :) You could down-clock it, under-volt it. You could probably even disable a couple cores if you want, or, do that conditionally using something like Tasker.
