So if I am reading correctly it seems both cores are not on all the time? That could be a reason why it feels choppier compared to epic touch
Both cores run when needed. Trolls dont bother me....

The problem is the fact the htc sense is one resource hogging *****.
You know, if both cores ran at once your phone would drain like there was a hole in the battery.
The second core kicks in only when it's needed, being that, there really isn't much of a need doing basic tasks.
Also, I haven't really noticed any choppyness in my phone whatsoever.
I run both cores and battery drain is no prob if set up right. Check other posts on topic and most are positive. My experience has been awesome

One of the reasons that the evo is so great is due to its processor. The second core runs only when it needs to, and/or runs at half the speed of the first until you need more power. This is done to conserve power and heat like others have mentioned. This feature isn't a bane but a boon for the device. Other devices don't have this method of processing (like the photon 4g). The photon 4g has two active cores all the time but during benchmarks it only out preforms the evo on certain marks, where the photon was designed to excel, like video viewing

Anyone's EVO get super hot after a little web browsing? I mean literally after about 5 minutes this thing is on fire. I'm rooted running viper's 1.2.1.
I haven't noticed it getting hot when browsing but definitely catches fire if using the camera for more than a few minutes.

I haven't used the camera that much yet. I didn't realize there was another thread that addressed this issue, and when reading some of the comments, I guess we do need to consider that this is a device running a dual core 1.5Ghz processor, so it's gonna generate heat. I'm using an app to monitor the phone temp. I guess I'll wait and see.
experience this on my gnex... was quite abnormal coming from a my epic... where there as no heat generated unless i Overclocked. Its just how these dual cores work especially at such a high frequency. You could try changing governors though. What is is your gov anyways? I switched from interactive to Ondemand and the heat instantly vanished. Can even use while on the charger and it barely gets warm.

I was running newts rls1 and getting 3600 quadrant and 6500+ antutu. When I switched to rls3 everything went down...so back to rls1 for me.
Other people have pointed out and I find this to work, that if you use setcpu and check "enable profiles", the 2nd core is turned on. I went ahead and set a screen off profile of 192/192 (max/min). I"m experimenting with these values, though. It seems I can knock down my mA use (per Battery Monitor Widget) by using the profile. The cpu does appear to be scaling properly. Many people have said not to use any of these cpu things and I did have some trouble with setcpu previously but it seems to be doing its thing with RLS1 anyway.

Programs probably just are't reading it right.
Speaking generally, the 2nd core will sit idle until needed, so it may be 'offline' when those apps check.
Until we get custom kernels/kernel source, there isn't much that can be done about it.

http://forum.xda-developers.com/showthread.php?t=1496934 If you read through this thread the OP talks about the mpdecision not working properly. Basically it's the file that governs when both cores are on etc. It is something that can affect synthetic benches, but not real world performance. Probably why current ****s given by HTC = 0. Quadrant = trash and benches are for jerking off to numbers which generally is not an indicative to device performance. But whatever floats your boat I suppose .

So I've been struggling with battery life on this rezound since I purchased it. It does get hot every now and then sometimes for no reason. I was waiting for aosp to come along to determine if it was just sense or the phone itself but since its not fully operational and makes my rezound hot as hell, I've stuck with sense roms for my day to day. The following screen shots are venom Rom desensed by me, including no weather, or facebook. The only thing syncing manually is gmail. That's it. No gaming here either. Downloaded a 7mb song, listened to mp3s with headphones and cruised the web a bunch.

That's about what I had using viperrez, although it seems your phone is discharging quickly when screen is off. I'd recommend under clocking when screen off to about 500mhz that works for me. Doesn't help with the screen on time though

1.) sense 4 is a MAJOR battery hog. id advise not to use ut unless your showing off
2.) i usually get 2hrs screen on, so id say NOT defective
3.) if you want like an extra 30-60 mins, try aosp. its fast and good on battery
hope this helps
Thanks for the replies guys I appreciate it. I did forget to mention something though... This is with the extended battery I know 2 hours would be about right on standard but I would think the extended should yield more no?

Most likely yes, isn't the extended battery 1.5x? Either way, battery consumption is hard to perfect. Like I said maybe underclock or find a battery saving build. Prop script to try I know system tuner pro has one built in.

Loving the DNA so far but I've noticed my kernel usage has been high. I don't think It's almost never been below 30%, at one point it was at 50%. From my understanding this is not normal and is creating bad battery drain. If anyone has any suggestions or advice it would be appreciated. Maybe I should try a different kernel? Here's some screenshots from a few minutes ago.

You can try a different kernel there are two different ones in this forum: http://forum.xda-developers.com/forumdisplay.php?f=1967 . However, the kernel is (are) the piece(s) of software that basically runs everything, so having the most battery usage out of the kernel is to be expected. The kernels on the form I gave may have better battery usage for multiple reasons (optimized resource usage, bloat removed, etc.) but it will (probably) still be the biggest battery eater.

Thanks. I was kinda thinking that. It makes sense that the kernel will be higher in percentage the less the screen is used and vice versa. Just seemed like my battery drain was excessive and since the kernel usage percentage was the highest I assumed that it was the problem. I'll give a different kernel a go and see what happens. Thanks again.

You think it's comparable to the Evo LTE? I would assume it's much worse, as the LTE has a larger battery and doesn't have that screen size or quality.

Well if it has the name "Evo" anywhere near it I ain't paying for it.
But then again I said that about the 3D and even this phone >.<
The s4pro chipset is more efficient then the s4 chipset. Just like how the s4 chipset is more efficient then the s3 chipset.
The OG evo uses more power and only one core(sloowww),the evo lte uses less power with more cores and a higher clock speed, I would assume the quad core chipset s4pro which is also 28-nm would have even better battery life because of the efficiency of multiple cores turning on only when needed.
However, the adreno 320 + a 440+ppi screen will take a toll on the battery, so playing HD games or using the camera would surely use a bit of power but not relative to the OG evo battery drain

PROOF?
S4 and S4 PRO uses the same krait cpu cores, both are fabricated at the same node(28 mm).
S4 pro is NOT more efficient but rather more powerful(2 cores vs 4 cores; adreno 225 vs adreno 320).
It should infact consume considerably more power especially if the apps you're running is multi threaded optimzed.

Whenever we talk about extra processing power or graphics resolution we have to flip the coin over and talk about the implications they have on battery life. One would think that, generally speaking, the more powerful the CPU/GPU, the more power it consumes. Too bad you’re wrong.
As processor technology advances a few interesting things happen. Circuit paths get smaller so power requirements drop. Less heat is produced so there’s less resistance which also contributes to a reduction in power demands.
As graphics processors get better they can take more load off the CPU which can not only make things look a whole lot nicer, it can also help reduce power consumption as well. It sounds crazy, I know.
I don’t think we’ll see batteries get any smaller (in capacity) any time soon, but looking at how much extra power is harnessed inside the the processors, the battery required to power them is a lot smaller than you might have imagined.
http://pocketnow.com/2012/10/26/snapdragon-s4-pro
Just a source,I am not looking for an argument as I did not create the s4pro,I have no say of how well it works as they intended.
My guess is that it has better battery life when using not so demanding apps ,gaming on the other hand probably uses more battery life but at a much better performance factor

How about you stop posting misinformation.
You clearly do not understand what you're talking about as all you did was copy paste.
As a said, Qualcomm S4 and Qualcomm S4 pro both use the same cpu architecture while the latter has more cores.
Both are also using the same node(28nm), so the stuff you posted about smaller circuitry as a reason it is more efficient then S4 doesn't make sense.
well obviously one says pro and one doesnt .....obviously the pro one is better becuase it says pro.
LoL
Well let's try it this way,the droid DNA has better battery life then the EVO 4g LTE even though it has to render more pixels,power a bigger screen & 4 cores instead of 2.
I do not know if the s4pro/prime is more efficient then the s4. And if I am wrong then I'm wrong and completely sorry if I came off hard on anyone. But I do know the droid DNA has stupendous battery life for its battery size.
