All about Samsung Galaxy S4

Do you have a source to back up what you're saying?

There's still a lot of battery confusion because what people think they know is related to the older nickel batteries. Don't deplete lithium batteries. Charge them when you can.

Specifically Nickel Cadmium batteries too. Nickel Metal Hydrides also don't have the memory effect and rechargeables have been those for years now.

It's interesting how these things get entrenched.

Quite a confusing source.

Anyway the Exynos 5 Octa is a much better processor than the Snapdragon 600.

Benchmarks confirm this.

You have a very interesting definition of "much better" when both is neck-to-neck while the 600 has better battery life and LTE:

That is a 1.6 ghz vs a 1.9 ghz snapdragon

find that same review with the korean version that is clocked at 1.8 or better yet a review that has them both clocked the same and you will see how bad the exynos 5 blows the snapdragon away.

a 300 mhz handicap is no joke and even with that it still beats the snapdragon in this review.looking at this review the snapdragon needs to be clocked at 2.0 to evenly match the 1.6 exynos soc.

Going by this review the snapdragon clock for clock is about 20% slower and going by 20% the snapdragon would need 1980 MHz to match the 1.6 GHz exynos and if you clocked the exynos at that speed it would blow the doors off the s600 soc

That is a dumb comparison. Clock for clock is never a good comparison. Different CPU's have different clock speeds. Remember the old P4's? That is a perfect example of why clock for clock is a useless comparison.

I'm not even saying the Exynos isn't faster.... it quite possibly is.

It's sammobile so take it with a huge grain of salt:

Seems a plausible explanation of why most of the S4s ship with the S600. After the Note 2, most of the noise/news was that all the S4s would ship with the Exynos Octo and it gradually got backed down to the situation currently where only a few markets get the Exynos.

No one doubts the raw performance of the A15 core, but the power consumption problems loom larger over it. Now reports that the Note 3 will ship globally with the S800.

 

[Germanic]

The Galaxy Note 3 will be such an awesome smartphone.

But for those of you who don't believe that the Exynos 5 outperforms the Snapdragon 600:

The Octa is generally a little bit faster than the Snapdragon in CPU benchmarks. But it's a pretty small difference.

Per Clock performance really doesn't matter in this case. We're a tech forum, we should know better. But the Exynos makes up enough ground that it's slightly faster. Samsung clearly chose clocks to make sure it was close.



Keep in mind most benchmarks being shown are done without any analysis and are pretty useless numbers. Exynos has much higher memory bandwidth but its actual CPU crunching performance ends up only a bit better. The GPU is also faster for some loads (i.e., OpenGL ES levels 2.0 or lower, Adreno 320 has advantage in 3.0).

So for example, the stock Antutu score of the Octa is around 30k vs 25k for the Snapdragon but bandwidth is 2000 points higher and GPU is also 2000 higher, which inflates the score despite it not contributing to computing performance. CPU scores end up within 10% or even close to tied!



Power consumption though is a huge issue. The Octa can stem the tide by relying on the A7 but then performance is lower than a 1GHz Krait. So far, battery tests have mostly been in favor of the Snapdragon depending on load (the more heavy the test, the more it leans towards Snapdragon).

I'm going to be honest guys,I have the gs4 on Verizon and I've had the nexus and gs3 and a few droids before that so I'm not a fan boy or anything but I am being 100% honest that my gs4 LAGS and feels slower then my gs3.I'm not even talking about regular tasks,even the web browser loading pages seems slow and its like the GPU can't push the1080p display.I get nothing but stuttering loading and zooming on pages like this one and they are a lot smother on the gs3.

I have also shut off all of the extra features the phone has

From all the things I've read about the exynos 5 not even the 1.6ghz version has these issues so benchmarks a side my gs4 doesn't feel as fast as it benches

You're experience pretty much echos what I've experienced with mine. Feels slower than my gnex did in some regards.

Where is "WatchON" on the Verizon version?
There is no icon but it's listed as a running process.

You don't see the purple WatchON app in your apps? There are two actual apps for it in the app manager, so make sure one isn't disabled.

 

[olds]

No icon and it's not disabled.
Doubt I'll use it but wanted to check it out.

DOH. I guess there is two ways to hide/disable apps. I was hidden.

Thanks.

 

[trmiv]

Weird. Its a cool app. I like it better for controlling my DirecTV than the actual remote.

Had issues with lag on my AT&T S4 until they pushed out the ota update and its been great since. Now I've rooted the phone and froze/removed most bloat and disabled Touch Wiz since I use Nova and its butter now. Devs are starting to release ROMs but I really don't have a desire to flash anything really. Gonna try Task650's AOKP build later today just to give it a spin.

I actually do like some of the Air Gesture stuff and do use the WatchON app so I really don't want to give up a stock ROM. I hope that with the Google Edition coming out they will build AOSP drivers for the IR blaster so it can be built into a CM10/AOKP ROM.

 

[ChronoReverse]

The first OTA made a huge difference for a lot of people. I'm using a ROM I slimmed down myself along with a custom kernel so it's been great even on Touchwiz.

 

[s44]

Beans (AOSP-themed TW) is out for Verizon. I understand people have been able to cross-flash VZ ROMs just with an appropriate kernel and APN.

Any TW-based ROMs from the GSM side worth trying?

 

[grkM3]

I'm about to order a Korean version and spent all night trying to figure out if I can get into a hidden menu to open up Verizon's bands.

Does anyone know if someone got an exynos 5 running on Verizon yet?

 

[s44]

Why would you want to? I don't think there's a single non-Verizon carrier/device that has LTE band 13. And I don't think foreign CDMA devices will work with Verizon's 3G.

Not to mention that Exynos Octo seems to have all the flaws of early silicon and is dev-unfriendly.

 

[rcpratt]

Still very unhappy with my battery life. Rarely get more than 2-2.5 hr screen time on a charge. Typical usage and usually on WiFi. Screen brightness is nearly intolerable low.

Guess I might just flash some ROM soon. It's already rooted...

You got something wrong there. I get 5-6 hours easy on a mix of WiFi and 4g

 

[s44]

I'm getting 4-5 with literally no attempt to save battery, Wi-Fi always on but never connected, lots of syncing...

same.

You guys are getting 4-5 hours?
