I personally think it's the latest UBUBMF3, something weird is definitely going on. When your phone doesn't go into deep sleep, it's very noticeable as that battery just drains like a leaky pipe... more people would definitely be reporting it! :silly:
[Galaxy S 4 i9500 Original Android Development] mw86:
Well before we have a giant one on one conversation in the thread lol, yes I agree seems its latest UBUBMF3 as im on same kernel without the issues, so it is in those details the answer will eventually be found. Im sure buddy, if i was seeing no deep sleep i know I'd be seeing battery dropping like a rocket. I mean the i9500 one big attraction is the unbelievable idle battery life it gets.
[Galaxy S 4 i9500 Original Android Development] Jimmy34742:
I'm on UBUBMF3, updated modem, camera fix, with Perseus 3.1, and I don't see any evidence of unusual battery drain.
[Galaxy S 4 i9500 Original Android Development] skivnit:
My i9500 is giving me a lot of deep sleep troubles. Both my s4 and Note 2 are on same wifi and same GSM network. After a 5 hours idle my gn2 lost 0 prct while the s4 7 prct. BBS shows wlan_rx_wake as culprit and I have no idea why

[Galaxy S 4 i9500 Original Android Development] jlevy73:
Have you updated to the newest UBUMF3 FW and modem? Seems that people on that are having issues in conjunction with the latest perseus kernel. I'm still on MEA and deep sleep with this kernel is fantastic with no unusual wakelocks in BBS or GSAM.

but the heat always with me

on whats app and 3g

the degree up to 34 c

when it is locked but 3g open , degree up to 30

when i am tethering the degree up to 38 !

when playing asphalt 7 the degree up to 42 !!!!

when i have s3 i wasn't feel heat like s4 at all

but degree on s3 maybe the same on s4

but thickness of s4 less than s3

so i am afraid the problem from hardware not software

maybe i am not sure

[Galaxy S 4 i9500 Original Android Development] bala_gamer:
those are pretty normal temperature, your mobile is safe, dont bother about the temps if the data you posted is true.
[Galaxy S 4 i9500 Original Android Development] mw86:
As Bala_gamer has pointed out those temps are normal. Clearly you are referring to battery temperature. Idle you may see 17-30c battery based on ambient temps. Combine high brightness from screen, a15 cpu usage, triple core gpu usage and radio usage (3g,hsdpa,wifi) you will see 30c at start and easy rise to even as high as 44c my guess, especially if gaming. The S3 didn't get as hot but close and the GS4 hotter as the total power draw from the battery is even higher. More power drawer equals more excess battery heat.

If you see close to 50 then I'd say you have a massive overheat issue. Cpu temps have an even broader range like 17c-106c which i have hit testing cpu heat limits under high stress of benches.

As Bala_gamer has described, based on your post ypu should not even monitor or worry about the temps you have hit so far. If you want to lower heat its simple. Lower power draw. Choose from any of the following. Use wifi over mobile data, use lower brightness settings, limit max cpu speed for extended gaming such as 1.2-1.4ghz vs above. Touchwiz power savings has a cpu limiter option, but just as easy to use an overclock app like stweaks. I had an extended battery on gs3 which under stress and mobile data high usage easily reached the 42c battery temp you mentioned.

Absolutely agree 100%

[Galaxy S 4 i9500 Original Android Development] cmd512:
3.2 fixed the deep sleep bug for sure, thanks Andrei. And, the audio settings are fantastic, with equalizer enabled and headphone volume amplification, I can't stop listening!

One tiny bug I noticed: If you take the equalizer settings beyond 12, they auto disable. In other words, for the low frequency / bands (bass), if you set it to 16 for example, it'll be the same as setting it to 0. The highest it can be set and have effect is 12.

(Not sure if this is a known fact already, my apologies if it is!)

Does anyone have a good middle suggestion on what to set the voltage and speed settings on Stweaks to get good performance and great battery life? I have set the upper limit to 1.4 while the lower to 1.1 and I have definitely noticed a difference in temp.but haven't messed with the voltage settings because I don't know what I'm doing. Just asking for a generalized answer.I use my device for a little bit of everything so I don't need it for one particular setting just a middle route.btw thanks andre for the great kernel.

[Galaxy S 4 i9500 Original Android Development] Simoleon23:
The kernel works fine but sometimes when trying to launch S-Tweaks, the phone freezes and I have to pull my battery out and reboot and sometimes it restarts itself. It doesn't happen all the time, but more probably when I have edited the earphone values in Audio play a song in Music player, launch STweaks. Its probably just me, but another thing is, when I checked 'enable registry hook' and 'enable master sequence', my screen's colors looked washed out. It'd be great if anyone could put up a guide on how to calibrate the screen and I wanted to know if it is possible to get rid of the tinting/ghosting effect using the settings in STweaks.

Just one more thing, there is no 'Interactive' governor in Perseus? The only governors I see is 'On-Demand', 'Performance', and 'Userspace'.
[Galaxy S 4 i9500 Original Android Development] mw86:
For the screen please go here to the screen calibration thread for this kernel.

http://xdaforums.com/showthread.php?p=42496874

If you're using the calibrated values by setting register hook and master sequence, and you feel the color is bland and washed out go to Stweaks and slide chroma value up slightly and apply and check a photo or something. Only raise the value as high as you need to have a pleasant looking color to the screen. :Cheers:

I suggest getting your eq set as you like and may run into the freezing when figuring that out but then when done leave those values and dont mess with those settings on a regular basis.

Can't say too much about this, but this is probably because our speakers are bad.
[Galaxy S 4 i9500 Original Android Development] REVERSiN:
Actually its not because they are bad its because they are tuned higher than theuly should which cuts the frequencies and disorts..... choose either quality or loudness cause this isnt a car AMP ;)

[Galaxy S 4 i9500 Original Android Development] bala_gamer:
with the current pretuned settings for speaker tuning the midrange dominates the rest of the sound resulting in audio quality which is kinda flat.. the best for now would be just increase the external speaker amplifier by say 4 or 5db, for me its personally more than enough. :):)
[Galaxy S 4 i9500 Original Android Development] mw86:
Do you have the speaker amplifier over 0? I noticed the new tuning makes the speaker louder based on the adjustments and whereas i would set 6 db increase before it now has been too excessive when the tuned eq boost for speaker is enabled. Since a speaker equalizer on each frequency is basically when raised is like increasing volume. So on certain frequency they are already boosted and applying a amplifier boost would likely push to distorted levels. So what you could do is set the amplifier volume boost to 0 or even use negative values to equal out the overall volume max that gets to the speaker. You may notice checking the tuned option the sound gets louder. I'd play your favorite music, max out volume and go to stweaks and drop the amplifier value in db one by one till volume is loud, speaker sounds clear and it still benefits from the tuned eq to the loudspeaker. :)

As was said above crackling is a sign the given frequency attempting to be reproduced was to much for the speaker in most cases its a given volume of a given frequency but by dropping the whole volume only one decibel a time the boost on the equalizer can be balanced to not cause distortion.

Any news for a 9505 version of this?

Sent from my GT-I9505
[Galaxy S 4 i9500 Original Android Development] jlevy73:
No because the I9500 uses a Wolfson DAC whereas the I9505 uses Yamaha. From my experience (albeit limited) Andrei only develops for devices he owns.

I saw a couple of sound mods in the I9505 section but the bottom line is Perseus + Wolfson will deliver a better audio quality

The new speaker tuning does make the volume louder, but i noticed something. When i reboot my phone, it becomes extremely loud. The solution is you have to simply change the speaker amplification(main speaker volume) to any value then change back to the previous value which you set before. Same db and the extremely loud problem is fixed. The quality is amazing!!!!!! Play games, watch movie and everything!!!!!! Good Job!!:good:

I have gain_1 set to 6, gain_3 set to 5, and gain_5 set to 3 (per your recommendation)... all with speaker amplification set to -3. This seems to be the perfect mix of volume + sound quality without any distortion.
[Galaxy S 4 i9500 Original Android Development] cmd512:
Hi Andrei,

Just flashed alpha3.4, reporting back that the new reduced speaker DAC volume (-3.5dB offset) causes overall volume to be too low in my honest opinion. If I try to set the speaker amplification above -3, I still get distortion / static on certain ringtones. So, -3 is still the sweet spot, but overall volume is definitely lower.

Anyway to toggle off this auto DAC volume offset?

[Galaxy S 4 i9500 Original Android Development] jlevy73:
+1, you read my mind.
[Galaxy S 4 i9500 Original Android Development] AndreiLux:
The point of the speaker tuning is to improve the quality of the sound on the speaker, the only thing I did wrong on the first settings was that I didn't take into account a wide enough dynamic range while testing.

The new setting should have no difference in overall volume compared to the tuning disabled.

If you want it louder again, then just raise the volume to counteract the offset and play with the gains.

As long as there is no distortion on the default settings (I hope not), it fulfilled its purpose.

It would have been good to have a proper higher quality measuring mic, but I had to do with what I have.

I'll keep an eye on how it goes.

If anybody has some other practical requests (other than what I mentioned already) regarding audio, I'm all ear.
[Galaxy S 4 i9500 Original Android Development] cmd512:
Could be some of the hokey ringtones I'm using then. I have to lower the gains quite a bit, and lower the speaker amplification to -3 to ensure there is no static / distortion.

Will keep messing with the gains and report back, cheers.
[Galaxy S 4 i9500 Original Android Development] AndreiLux:
Any distortion you would have can only come from band 1 as that's the only other positive band, and band 3's +4dB is counteracted by the -3.5dB on the general volume. Everything else are adjustments to spikes in the frequency response. If it weren't for the distortions on this ****ty little speaker, band 3 should have been much higher.
[Galaxy S 4 i9500 Original Android Development] cmd512:
Yep, good catch, was just about to report that reducing gain_1 to 5 allows me to raise the speaker amplification to -1, which brings the volume back. Anything higher, and I get static on several of my ringtones.

5 / 4 / 3 for gains 1-3-5 @ -1 speaker amplification seem to work best across the board on the latest alpha3.4.
