I think the battery performance is due to the difference between process nodes. I believe Exynos is on 32nm node and snapdragon is on a 28nm node.
One thing that should me worthy of the mention is that it's very likely that the Exynos version of the S4 will never reach the same level of development as the Snapdragon variant because Samsung aren't willing to play ball with the documentation for the chipset.
Everyone seems to forget that PRIOR to an update AFTER release, the i9505 had a closer rating to that of the i9500.
TALK TIME went from 13:53 to 18:03 (i9500 is 11:01)
WEB BROWSING went from 8:42 to 7:24 (i9500 is 6:58)
VIDEO PLAYBACK WENT FROM 10:16 to 12:30 (i9500 is 11:29)
So its not the end of the world.
Can most likely be improved with a software update.
Ronny, 28 May 2013Well, most tech geeks would probably opt for i9500 rather than i9505 mainly because appreciati... moreIn Hong Kong, most people preferred S600 version, due to the LTE speed advantage...

As I used to visit a Chinese market that dedicated in phone, that a person I met there told me every korean version machine they got are just phones that purchased by people in korea and then they feel unsatisfied or for other reason so they send their phone back to carrier and as those phone are used sothey ccan't sell them again and therefore dump them to other country...I don't know if korean version phone in other country sourced same as those in China, but I had never buy any more of these since then...
Have owned both phones and the i9500 is noticeably snappier in real world usage. Had to swap from my i9505 due to significant audio distortion with low impedance headphones, which many high end headphones are.
Yuriy Samorodov, 29 May 2013Yes, it is if you don't mind to use higher impedance headphones.Why do you say that?
BTW, as someone mentioned below, 3G talk time comparison is very shocking.......
Could you leverage what Modem processor has been used with Exynos?
It is about the Modem isn't it?
Yes, it is if you don't mind to use higher impedance headphones.
the snapdragon version has similar performance - but has better battery usage and has LTE. so this is the better version!
what is the link where can i download the wallpaper of the galaxy s 4 the white one
adam christian, 28 May 2013Korean Version S4 (SHV-E300) - available in the Philippines....really? if so, where/what site ... morecan't find it using google?
then try Sulit.ph ^_^
the legit seller is in Greenhills
search for S4 32GB shv-e300.
planning to buy one tomorrow for myself ^_^
I could've sworn in all other tests the Octa actually had notable difference in benchmark. Especially GPU. This doesn't make sense.
Looking at the results (performance and battery) there isn't any reason to get the octa core SGS4 yet.
I still think the concept has merit and further software updates may deliver improved battery life.
That said both phones are still right up there on both fronts.
Look guys...I am sure that siyah will make a custom kernel for 9500 and then u can check the real performance of a15...on s3 and s2 siyaj made a mod that we can choose how mant cores we want to use and this will be on the 9500...we can choose cortex a15 only or cortex a7 and different mode like 2 cores of a15 and 2 cores of a7 then u can see much better perfomance or if u don't like that overclock at 1.9 ghz the a15 and then compare it with the 1.9 snapdragon...and remember for the gpu...if u overclock sgx544mp3 to 600mhz+ like on s3 with mali 400 u will see REAL PERFORMANCE
Samsung just conned a lot of people into buying "Octa Core". It's just two quad cores people! And it's not even efficient!
bob, 28 May 2013Yeah i have 9505!Read the comment that's over/after your comment.
I'm sure that Samsung on purpose, didn't optimize the battery life of S4 Octa version, so to sell good S4 Snapdragon 600 version now, until they catch up with the production of Exinos Octa.
If you don't believe me read about big.LITTLE Processing, battery management.
When Samsung is ready with the supply of Exinos Octa, one update will do the miracle.
