I would get UAG case now since you will need a protection for your phone, and then wait until Zerolemon starts to ship their battery in a few weeks to find out if Defender could even be modified for it. Don't buy Defender yet. I can tell you that most likely I will be getting Zerolemon battery myself and I have Defender (fake) which I'm going to measure up to see if mod is even possible (which I seriously doubt).

Actually, the more I think about it, the more I consider Zerolemon as a specialty battery battery for watching movies during your commute or on a plane or when you are on a long trip, etc. For that occasion Zerolemon guys fine-tuning their TPU case to give you a good handling grip, lip protection, and basic case to hold it together. Having TPU case is convenient to switch between Zerolemon and regular battery w/UAG. No need to unlatch and remove multi-layer parts of the case. I also been told by Zerolemon team they are working on a rugged case which might be your everyday solution for their battery. Depending on that case, I might end up dropping all of my other cases and switching exclusively to it!!! It just so great to have this multi-day battery freedom :)

My point, don't invent into Defender yet, unless you already bought it and can't return it.
[Galaxy Note II Accessories] casualftw:
I bought the Defender case already but the ebay seller agreed to let me cancel the order. I'll be picking up the UAG case and wait on Zerolemon to release their battery. Thanks for the advice guys, and if you have anymore recommendations for accessories let me know:)
[Galaxy Note II Accessories] farfromovin:
I dont think the defender will be able to cover that monster. I mean, it bulges with a 6400... I guess we'll see around mid-late April when the zero lemon ships.
[Galaxy Note II Accessories] LittleRedDot:
I don't know about you guys, but if I were to buy a zerolemon I would probably never take it off. I would just get used to the 5+ days of charge and could never go back to stock battery.
[Galaxy Note II Q&A, Help & Troubleshooting] 4l3xXx:
Hi there! It's been 3 days I own a beautiful GT-N7100

I immediately rooted it, installed Perseus Kernel and started playing around with some undervolt - overclock.

From what I understood from my continuos benchmarking efforts, going over 533 MHZ for the gpu is useless, as it throttles immediately, and sometimes it even kills the performance.

So, regarding the GPU, this is the setting:

160 Mhz - 825 mV ---> MIN

266 Mhz - 875 mV

350 Mhz - 950 mV

440 Mhz - 1000 mV

533 Mhz - 1025 mV ---> MAX

It looks to be stable. Now, this is the CPU:

1800 Mhz - 1250 mV ---> MAX

1704 Mhz - 1225 mV

1600 Mhz - 1150 mV

1500 Mhz - 1125 mV

1400 Mhz - 1075 mV

1300 Mhz - 1025 mV

1200 Mhz - 1000 mV

1100 Mhz - 1000 mV

1000 Mhz - 975 mV

900 Mhz- 950 mV

800 Mhz - 925 mV

700 Mhz - 900 mV

600 Mhz - 875 mV

500 Mhz - 850 mV

400 Mhz - 825 mV

300 Mhz - 800 mV

200 Mhz - 775 mV ---> MIN

You may be wondering "Ok, so what's the problem?" As the title says, the CPU has the bad (or good, as it prevents itself from frying) habit of throttling all the way down to 800 mhz whenever its temp hits 80°C

This happens extremely fast @1,8 ghz, so fast that I wasn't even able to determine for sure the temp it hit before throttling.

@ 1,7 ghz it takes a bit more, but the end result is the same when it hits exactly 80° (it doesn't go over)

@ 1,6 ghz is stable, it never goes over 75°.

It looks that every 100 mhz I have a 5 ° increase in temp. It's not good for sure, and as far as I'm concerned is too much of an increase.

Should I further undervolt the top two frequency scales?

EDIT

Tried 1,8 ghz @ 1175 and 1,7 ghz @ 1175 and still the same s... you know what.

Or better said, it's a bit different:

1,8ghz @ 1175 takes more time to go to 80° C, but it still does.

1,7 ghz @1175 stays at 75° C, but the stupid pig throttles to 1 GHZ this time...

Any ideas?

[Galaxy Note II Q&A, Help & Troubleshooting] baileyjr:
Your experience is exactly the same as mine. Even with undervolting I still hit the throttle range at 1.7 and 1.8.

I concluded that overclocking only really gave me an advantage in the benchmarks and braging rights department. If I was playing a game it was pointless as after a while I hit the throttle limit. In end I went back to 1.6 ghz, and I'm more than happy with the performance. :good:
[Galaxy Note II Q&A, Help & Troubleshooting] 4l3xXx:
Hi there, thank you for being interested in my situation. After playing around with the values, recovering from bootloops, freezes and instabilities, I came to a strange conclusion, which I would like to share with all of you, in case someone is living in my very same situation.

It looks like the voltage was not too high (causing the heat), it was rather too low. It looked, after some studies, that the cpu throttled not because its temp was too high (it sometimes throttled at 55°, and other times was not throttling at 80 ° :confused:). So this is what I understood:

- Voltage was so low that it not only caused random lag spikes, both in games and in the UI as well (as I was also wondering why in the hell NFS was running worse than before), it caused the cpu to throttle itself to the highest step with enough voltage to support the demand (800 mhz, or 1 GHZ, at first). So I tried putting very low voltages on all steps, except on 1.8 ghz (I was on performance) and default voltage on the 1,2 ghz step, and it soon throttled to 1,2.

- GPU voltage is OK.

- Yesterday the CPU was going all the way up to 75 and also 80 degrees not only because it was charging, also because it was near my laptop's vent, stupid me :angel:

I know this makes no sense, but it is known that very low voltages prove to be unstable, but I couldn't think they could prove SO MUCH unstable.

The results now are these:

- 19k in Antutu

- 8k in Quadrant

- 60 fps on Basemark Taijii.

- 20 minutes of stability test, with over 170 gpu passes and 45 cpu passes, and no throttling at all (always 1.8 ghz).

I'm trying to play some NFS:MW later this afternoon, just giving the phone some time to charge, it's been a hard day for it :D

Any comments will clearly be appreciated. I'll come soon with my current voltages to share with you :)

And, by the way, I love this phone, I'm having sex with it this night :D

[Galaxy Note II Q&A, Help & Troubleshooting] 4l3xXx:
Alright, I can tell you it was being throttled because I was running the System Tuner app. By the way, I thought I won too early. For some reason my phone still throttled, with voltage having been decreased only by 50 mV on all cpu steps and by 100 mV on all GPU steps. It also throttled on 1.6 ghz max. Stock voltages just made the process be slower. Stability test was perfect as I told you, but Nfs MW seems to be heavier than the test itself. I came to the conclusion it was time to switch from Perseus to Neak. So far so good, running at stock voltages and everything runs way smoother, the damn game as well. Battery isn't that good with stock voltages, also considering that kernel's voltages are way higher than sammy's defaults. I am trying undervolt again on this kernel, without touching the clocks, and will report back, starting with -150 mV on the gpu (the 160 mhz step is @ 950 LOL)

EDIT;

This phone is becoming extremely stupid and is starting to seriously piss me off. I can't do sh... because it throttles. Undervolted and throttlrs, downclocked and throttles, overvolted and throttles, someone please tell me what the HELL is going on before I throw it out of the window.
[Galaxy Note II Q&A, Help & Troubleshooting] K99:
hmm, I saw somewhere someone mentioned that battery temperature at 36 degrees is throttling down, but I don't know. I think its worth to try and monitor battery temp also.
[Galaxy Note II Q&A, Help & Troubleshooting] 4l3xXx:
That could be reason, I mean, undervolted throttles because of too low voltage, stock voltage throttles because of what? CPU temp? Hell no! 60 ° the max I reached with stock voltages and stock clocks, and still throttles? There HAS to be something else going on.

I also read something about the battery here on xda, from the thread I actually took my previous voltages from. It was saying 41° was the battery temp that once reached would throttle everything. The guy also said it is a "security" protocol that's present only on Sammy ROMS.

I actually think the temp is way lower than 41°, because I can tell for sure the battery doesn't reach 41° at ALL, so your 36° info may be totally right.

Changing ROM might be an idea I guess, if the "security protocol" stuff is right. I'm eventually switching to Omega ROM, I've seen a lot of people with it.

I'm actually monitoring the battery temp right now while I play that stupid NFS game. I'll report back as soon as something happens.

Keep in mind my actual voltages are as follows (NEAK defaults)

1600 @ 1313 mV

1500 @ 1263 mV

1400 @ 1225 mV

1300 @ 1175 mV

1200 @ 1138 mV

1100 @ 1100 mV

1000 @ 1075 mV

900 @ 1050 mV

800 @ 1013 mV

700 @ 988 mV

600 @ 963 mV

500 @ 950 mV

400 @ 938 mV

300 @ 925 mV

200 @ 913 mV

And GPU

160 @ 937 mV

266 @ 962 mV

350 @ 1012 mV

440 @ 1075 mV

533 @ 1137 mV

By the way, thanks everyone for your interest and for trying to help a poor noob :highfive:

EDIT

K99's point is absolutely CORRECT. Whenever the battery reaches 35-36°C the CPU is unable to go over 800 mhz, no matter how low the CPU temp is. The CPU temp can even be 30°C no matter. Now, any idea of a good ROM NOT based on Samsung's stock with 4.2 and s pen support? Will report back and tell you if that security protocol stuff is true.

And another question. How can I backup an ENTIRE app such as that stupid NFS game to just put it back on the new ROM without having to download it again? (I have monthly limits on my connection...)
[Galaxy Note II Q&A, Help & Troubleshooting] ahkiongkc:
For backing up app with data, use titanium backup.

Apparently Samsung can't supply enough of their Octa Core prcessors and are reserving them for non LTE countries in Asia and Africa.

70% of the first 10 million handsets will have the Qualcomm quad core.

UK, Europe, US and Australia will not recieve the Octa Core!

[Galaxy S 4 General] slapdaddy:
But is there really going to be that much development for the Exynos S4? I've been hearing horror stories about devs dropping support for the Exynos right and left.

Sent from my HTC Vivid.
[Galaxy S 4 General] r1sh12:
I have a feeling the octa will be in the note 3,

With the launch event, they have essentially marketed the wrong phone.

Im still torn, because all I usually do is root the phone and remove the bloatware.
[Galaxy S 4 General] Livebyte:
This is fantastic news.

S 4 Development will be thriving for most of the versions! :o

And if you guys were expecting newer versions with Exynos, don't put your hopes up too high, it'll likely be in the Note 3 as standard.

But it will be incredibly sad news to anyone who wants a thriving Exynos S 4 development,

this includes future Note 3 development if Exynos comes as standard.
[Galaxy S 4 General] Obagleyfreer:
I agree with you. I'm quite happy that the majority will have the Quad core, the dev scene will be great!

Most devs have sworn not to develop for Exynos devices as Samsung won't release sources.

And now that the same SOC will be used in US, Europe and Australia it can only be a good thing!
[Galaxy S 4 General] BarryH_GEG:
Let's deconstruct the story...

Link? Reports "out of South Korea" come in all degrees of accuracy.

Follow the link and it's to a story about Qualcomm officially announcing the S-600 will be used in the SGS4. At the bottom of the story it says Octa's on track for the SGS4's April 26th launch data. Not a single mention of where S-600 or Octa will be used.

Huh? We already knew LTE heavy countries would be receiving S-600. But 2/3 of the world aren't LTE- capable yet. So it's probably safe to assume the 1/3 of LTE counties have lots of wireless subscribers so they probably will make up half of the SGS4's sold. I'd find it hard to believe that 2/3 of the non-LTE world (Africa? Seriously?) make up 30% of smartphone purchasers as the story claims.

What report?

The link to Unwired they provided says the opposite and their coverage is less than a week old.

So, until the credibility of the "report" that's repeatedly quoted can be verified I'm taking this one with a grain of salt. I don't consider SamMobile a terribly reliable source but at least their S-600 vs. Octa deployment schedule had some detail attached.

P.S. - A gazillion sites quoting TechRadar's claim of "70%" doesn't make it any more credible unless the missing "report" itself turns up and is in fact credible. If there's any mobile device out there people are interested in right now it's the SGS4. How many clicks throughs do you think TechRadar's gotten off that story? ;)
[Galaxy S 4 General] Obagleyfreer:
Very valid points!

I need to stop believing everything I read on the internet, it's going to get me into trouble haha

That said, I still believe there is "some" truth to this.

And we all know that the majority of countries will get the Quad Core over the Octa Core, simply due to LTE.
[Galaxy S 4 General] SlimJ87D:
Well what's the percentage when we do our own numbers? I think we know a good amount that will be using the Snapdragon confirmed. What if we assumed that all the other versions are using Octa, what would the percentage be there?
[Galaxy S 4 General] AndreiLux:
Sometimes I think you're just arguing for the sake of arguing, and have some real contextual interpretation issues. Here's the original article to help out: http://www.etnews.com/news/device/device/2739089_1479.html#ystfuv It contains much more information than the English counterparts.

Is it really that hard to believe that a $650+ high end phone might not have a very high market-demand outside of first world countries?

North America, Japan, Korea, Australia, and basically every relevant European country is getting the LTE variant. In terms of market size that only leaves out China, India, SE Asia, and maybe South America, and as I stated, even if they outnumber the first-class countries 3:1 in population, that doesn't even nearly make up for the income inequality and the simple fact that a high-end smartphone is a luxury item there.
[Galaxy S 4 General] Livebyte:
The only countries that matter in Asia are Singapore, Hong Kong, South Korea, Taiwan & Japan.

Others are still emerging markets which means high-end smartphones like the S 4 has little relevance there.

Deal with it people, Qualcomm versions are definitely going to be the majority of the S 4's.

One year later, you won't regret it.

Mark my words.
[Galaxy S 4 General] AndreiLux:
Correct, and those markets combined are still only half the size of the US market.

To have a bit of scale:

And that's only what fits the smart-phone definition, high-end expensive smart-phones like the S4 is again drastically skewed.

I can't find the quote anymore but I remember that Europe alone consisted for like 50% of the last S series sales, worldwide. Now count the fact that Europe is getting the LTE version in the biggest markets...

Don't be so sure about that. The only reason this situation even came to be is because of Samsung's manufacturing problems. Once they have sorted that out do you still think they'll willing to pay $30 per phone in components to Qualcomm when they could have sourced it cheaper or have that money returned back internally into the company? You might very well see the numbers going belly up in favor of the Exynos later in the year.
[Galaxy S 4 General] FinancialWar:
Kinda true, you'll be worrying about what's in the S5 in 2014
[Galaxy S 4 General] Livebyte:
Hah. Try to find someone here in Singapore that doesn't own an high-end smartphone, I'll give you a dollar for that.

If you don't have one, you'll basically be an outcast here.

I'm still hanging in the middle about that.

It could either go both ways.

I'm hoping it will stick cause it will hinder development for sure.

But one thing I'm sure, if they have sorted all of this out, Exynos will definitely be standardized across all versions of the Note 3.
[Galaxy S 4 General] BarryH_GEG:
It's almost impossible really. Some Asian countries have large numbers of mobile users but low percentages of them can afford high-end smartphones. Some have tons of high-end smartphone users but their populations aren't all that large. For example, VZW in the U.S. has almost as many subscribers as all of Japan.

Unless something's gone horribly wrong, Octa would be the SoC Samsung would push wherever they could. It should cost them no more than S-600 to produce (if it does, they screwed up) and rather than giving the mark-up to Qualcomm they'd keep it in the Samsung empire. So the rumors could be true and Octa's going to late, there are heat and power consumption issues, it's only meant to be used in Africa, and it's useless because 70% of end-users are on LTE. Or they might not.

With launch (theoretically) a month away and very little coming out about Octa itself or where it's being used I'd guess something's up. On the bright side maybe performance and battery life is so much better than S-600 their struggling with how to position two such different devices as "the same."

I guess we'll know soon from the horse's mouth. ;)

---------- Post added at 06:36 PM ---------- Previous post was at 06:30 PM ----------

Samsung sold 60MM "smartphones" in Q4 2012. Of those, only 15MM were SGS3-class or higher. The closest you'll come to markets rich in high-end smartphone users is to use Apple as a comparative as they only sell high-end devices and are who Samsung's aiming for on the high-end. Here's a sobering stat. 60% of devices sold in 2012 were "dumb phones."
[Galaxy S 4 General] Brendo:
So, there is still no proof about which processors supports lte (however I'm pretty sure it's actually separate to the cpu these days?). Initially the thought was snapdragon for the us lte bands and exynos for other lte bands. The htc one snapdragon supports main lte bands (800/1800/2600. Missing 1700/2100/2300), so in that basis could be sold all over, but then wether the exynos supports lte or not, what's stopping it from being sold all over as a 3g phone?
[Galaxy S 4 General] AndreiLux:
Both processors in this case don't have integrated LTE and both in support LTE via a separate modem. The whole story basically has nothing to do with LTE itself. It's just Samsung keeping two designs instead of three out in the market (for the moment).
[Galaxy S 4 General] BarryH_GEG:
And I think you're pissed off at me because you weren't happy with my reply to someone asking about black crush in another thread. And my contextual interpretation abilities are fine.

[Galaxy S 4 General] Obagleyfreer:
I didn't think it would be down to LTE 100% afterall the i9305 has a Exynos SOC and LTE.

I think I might just wait a few months and see if Samsung release the Exynos version with a Qualcomm LTE modem like they did on the S3 :)

@AndreiLux, as a long time Perseus user and huge fan of your work I was wondering if you will be getting the S4 and developing a Kernel for it?

If so which one, Exynos or Qualcomm? :)
