[Discussion][Perseus Kernel][GT-I9500]

To keep Andrei from going crazy with non-development related questions, I've opened the following thread. That way we keep the development thread for development topics and this for general discussion.

Good deal.
First feature request: Fading in/out LEDs! I've pinged the dev for LightFlow, and while he can implement it on a software level, it would be supremely inefficient and probably drain the battery like crazy.

Actually that's something which belongs in the dev thread. If anything you can just post on the issue tracker on Github, I've grown vary of XDA.
There's a new TI LED controller so I can't port the old Philips controls from the old phones. I'll rewrite it eventually but I got other things to do now.

Done, posted on Github!

just got my s4 one day ago. rooted immediately, flashed omega7.0 and the latest perseus. did not touch anything on the u/v in stweak. no o/c as well. but the antutu score is so low 21000+, i thought it at least supposed to be 27000+?
i tried adam kernel, had the same result. is that normal? did i miss anything?

thanks for you response. as i mentioned i got it only one day, without touching anything on u/v & o/c. i guess this is considered lower score than the stock one? i merely care about bench mark, i just want to know is this normal? or i need few days to let it settle down? fyi, i tried more than 10 times and it only score between 20k-21k. perhaps you can be kind enough to give me some idea rather than congrats me.

It is normal for benchmark to be lower than on stock kernel all devices differ. Following the development of this kernel it has been stated that the kernel is not intended for high benchmarks but more for overall stability, smoothness and better battery life.
Benchmarks is just a number and a high benchmark does not always mean your phone is smooth and performs very well under normal user conditions.
Hope this answers your question and should I be mistaken about anything anyone welcome to rectify me on those points.

i never meant that perseus is running low on benchmark, in fact, it's the highest between chainfire's cfroot, wanam's adam. i tried all these 3 kernel, all score only between 19k-21k. i just wonder if i have accidentally limited my cpu speed? i will do a factory reset and re-test it.
again, i dont or merely care about benchmark, i just care if my s4 is running normally.

I have kanged Andrei's response with respect to benchmarks.

Benchmark freaks can enable the boost mode manually: /sys/class/thermal/thermal_zone0/boost_mode .
The first throttling speed is 1400MHz and that's why it spends a lot of time there during benchmarking.
Effectively, overclocking on this device makes very little sense unless you can achieve more thermal headroom with undervolting. I personally couldn't get over 1.8GHz on random loads, and couldn't get over 1.7GHz on benchmarking (Antutu 31300).
Nevertheless, the option is there for people who want to stick their phones into their freezers. For everybody else, stop being concerned about numbers.
This seems to affect only a rare number of people and I still don't know the cause. Just cycle the screen once and be done with it.

did you guys note the download link for perseus alpha 4 rc1 on andrei github? , dont flash it unless you know whats in there
edit: just flashed it (couldnt resist). based on the newer sources it seems, camera works fine with latest cam firmware

lets wait for Andrei release......build seems to be a release candidate....so its should not be for long....

@Power, What rom are you running? I suspect it's rom related.
I'm using omega 7, one of the user experienced the same as mine. Going to flash new rom.

Low benchmark scores after franco kernel r33

i used to get around 32k in antutu and around 18k in quadrant before franco kernel r33 but now i am getting around 24k and 11k respectively i highlt doubt this is due to kernel (i didnt screw up anything (no custom roms nothing...)) can some confirm this ?? plzz

Why does it matter? Does the phone still run good? Can you notice any difference while using your phone normally?

in practical sense the phone works perfect apps run smoothly and battery life is awesome (5-6hrs)...but theoritical sense why did the scores become less ?? did franco limit the processor speed or something??

This bit is the only thing you should be caring about...
The 'score' is meaningless. Let it go, uninstall any benchmark apps and don't bother running a test ever again.
Put it this way...if you suddenly scored 234069823987693827469823764 after flashing a new kernel, but performance and battery actually got worse, which one would you prefer?

Hi,
Franciso explained that he had decreased the CPU temp limit before thermal throttling, that could explain your lower score (earlier thermal throttle)... Check also your max CPU freq.
Let cool down your phone before you run Antutu and see, or play with the thermal settings (raise a bit the CPU temp before thermal throttling, core also).
The user is in its right to know why he have a lower score in benches between two different version of a kernel, whatever if a bench is useful or useless... Obviously if all is smooth and run perfectly for you, it's the principal.

nexus 5 is high end device, benchmark score doesn't effect the performance of device using any kernel.
i never experience any lag on my nexus, i always get different score in antutu.

r32 I got around 32k with antutu now I get around 29k on r33 but battery life is so incredible I'm willing to sacrifice benchmark points useless in day to day use .... isn't benchmarking moslty about bragging?

thank you very much

Post your Antutu Benchmark Scores

Its simple...I've made this Thread to whoever wants to share their Antutu Benchmark scores, also please share any modification you've done to the device, thanks:fingers-crossed:

Remember this benchmark runs better when phone is cold, Can you share some screenshots?

That's pretty low, as the note 4 with the right rom will do 52,000, anyone have a quadrant score to report? One stock and maybe one with xposed installed?

Got about 52,800. I didn't expect this phone to perform. It works fantastic in day-to-day use. I don't 3D game. Can't ask for much more from it (except more battery life - but removable battery is its saving grace).

For a 6 cores phone basically 2 high performance cores, these results are not bad, im coming from a Note 4 with Exynos Octa Core, this phone is much smoother, also after rooting and freezing some apps with Titanium Backup, I was able to get 27 hours and 4+ SOT, I say, once developers gets their hand on this phone, it only will get better :fingers-crossed:

Why don't you run a successive antutu a second and then a third time back to back and post the scores.
Nobody runs a phone cold, its already warm and then they want to do more stuff.
Lets see how this thing does.
An 808 should not drop below 45k. The 810 throttles much more.

What ROM/kernel should i flash if i want the best possible battery life?

So far i have tested RR, Nuclear, Omni and Sultan... Anything else i should test? Thanks for the help.

Just flash darkobas n feel the change in your battery life

I can get about 5 hours of SoT on those ROMS which is pretty good, but some guys have said thay can get over 6 so i want try and achieve that. My daily usage is mostly scrolling through social media, i hardly play any games on my phone.

Thank you. My usage is almost the same as yours except no game and almost on wifi. And I have the same battery life on Omni and Darkobas.

NucleaROM + UKM. I can get around 8 hours SoT (or 5 playing with a DS emulator). Highly optimized for our devices and the kernel is as close to AK as it gets. I can get a smooth experience with 2 cores hovering between 883MHz and 1.5GHz which definitely helps. With DraStic, my phone hardly goes above 3 cores at 1GHz. Scrolling is silky smooth even at single core 1.5GHz.

It's the flashable zip that allows kernel tuning via Synapse. Should be somewhere in the OP.

Yup. That is so true. I have a friend whom I gave my pixel 2 XL when I got my Op6. The pixel 2xl with the last gen processor has a weird silky smoothness in it's UI. I can't explain it. Just use one P2XL on Android P DP2 to understand what I mean.
Benchmarks died with Snapdragon 820±
