i might get violent if someone drop my n4...

got from Hotspot Lowyat...

ps: back then, google store out of stock, and digi not even selling yet... digi starts selling like 1 week after dat. i want this phone so much~

wow, that is 1 very extreme aggressive UV. it's like -200mv.

not agree...

Display S4 vs N4:

S4 is PenTile matrix. Nono for me. Many people hate it, including me.
S4 max brightness = 404, N4 max brightness = 608

CPU Snapdragon 600 vs Snapdragon S4 Pro:
- Only difference is 600 running at higher freq and larger memory bandwidth
- IMHO, larger memory bandwidth has neglectable effect for phone. My benchmark proven it (sort of).
- GPU is the same - adreno 320.
- From the benchmark, I can safely assume that if you push your S4 pro to 1.9ghz, you will get the same performance as S600... without any other optimization.
- My 1.7ghz with tweaked already at the same performance as S600 @ 1.9ghz.

agree. benchmark only tell 1 part of the story. and in this case, i m comparing specifically on S600 and S4 Pro.

ps: there are people who still care about benchmark.

agree. i like my ipad more than my transformer...

Google still have a lot to improve in the tablet front.

not arguing.. just making a point.

ok, about the display, i have not see the S4 in person yet, so, cannot compare. but generally, i like brighter display like Retina and IPS more than Amoled.

i compare my friend's note 2 and my nexus 4 side by side, both playing same video at highest brightness. everyone can tell n4 display is much better.

ps: about battery life... i can tell u specifically which CPU uses less power (s4 and s600) by checking the mV they use in the freq table when sammy release their kernel source. i suspect it's the same. but most battery benchmark are inclusive of all, screen, wifi, battery size, etc... that chapter, i think S4 with bigger battery will win...

Benchmark does not matter for those who choose to ignore it.

For example, no matter how many time you run Antutu, you will still get around 17k.

But if u recompile the memory routine and math functions of the OS with Krait specific instructions, your Antutu score will jump to 21k. That is not fake jump. All your memory copy operation and some math operation are really faster; thus you see improvement in benchmark.

Same phone, only some stuff are running faster due to better code.

Don't mistaken benchmark performance with smooth operations, which mostly depend on your CPU governor...

ps: if ur point is that 17k and 21k make no difference to u, you have a valid point. the difference may not be noticeable in your daily usage. you may see the difference when you do a memory search looking for some value in the phone (useful in cheating game )

i care about benchmark, that makes me iFag and/or samsungfag?

no one should "trust" benchmark. it is something for u to used as reference. and most benchmarking score measuring certain aspect of the hardware, for example, performance. that alone is not enough if u wanna look at the overall "experience".

unfortunately, there is no benchmarking program to date that can measure "experience" yet...

April's Fool...

based on the value in your screenshot, assuming you are on "Fast" cpu, you have already running at -100mv.

Oh you have other browser can you tell if the battery is better or less heat when using browser other than chrome? Asked because some user say phone get hot in browsing. Thanks.

interesting. thanks for sharing.

Kraits and bionic optimization speed up 2 things in your phone:

1. string / memory operation. these operation including string copy, memory copy, compare, etc. even a simply file copy uses these operation. all these implemented in a library known as bionic library in android. it's similar to libc in pc. this is the bionic optimization.

2. after Qualcomm introduce krait core (since S4), they release new code that allow you to use extended instructions that can only be found in Krait core to do some math operation. by implementing these new code, some math function such as sin(), cos(), etc will be faster. Many heavy graphic app uses math functions.

What custom ROM/kernel developer do is to get these code from Code Aurora, and implement in their ROM/kernel then recompile it. You may not notice performance improvement if you just swipe homescreen, etc but if you do benchmark, you will see a huge improvement.

For example, before any optimization, most N4 getting like 17k Antutu score. After Bionic optimization around you will get around 19k. You should see huge improvement in the RAM score, in this case 3274. Also check out the CPU floating point score, 2139, in this case, not optimized yet.



Now, if you optimize the math library with Krais extended instruction, you should see huge improvement in CPU floating point score, in this case 4182. With both optimized, you see a jump from 17k Antutu score to 21k, around 30% improvement at the same CPU speed.

this is 1 of the most severe drained i have ever seen.

mine mostly around 1-2% when sleep.

try switch to flight mode before you sleep if u really worry about battery drain during sleep.

me not much. i just UV. previously i prevented mpdecision to take control of my CPU speed. tested a little. not much battery improvement. so now, just UV. nothing else.

i dont worry about it's battery as it is enough for to get by in a day. typically i only charge once every 2 day.

so now, i want my phone to be as smooth as possible whenever i use it. mpdecision will auto push to 1ghz when i touch the screen. while others may see it as problem, i see it as feature.

and for someone to drain 27% during sleep, it's probably not problem with kernel wakelock. most likely some app.

instead of just flashing ROM, how about Battle Cats?!!!!

must play! free. no internet required. fun!

no internet is required.

stable and smooth? nothing beat stock ROM... i m still on stock rom.
