KingX v Ziggy v Lou Kernel?

I'm lucky enough to have multiple Inc's I can compare side-by-side. This week, I took the time to test-drive a few Kernels.
My goal is to find the (1) most stable, (2) best performing w/good battery life. Basically undervolt kernel testing.
Unfortunately, I really can't find much difference between these popular variants.
The battery life seems to be roughly equal on all of them, as does the stability (barring IcrediKernel, which had some issues in my testing with SkyRaider).
I tested (all current versions as of 1/10/2011):
* Redemptive with Lou's included kernel
* SkyRaider Sense with Ziggy's kernel
* SkyRaider Sense with KingX kernel
* SkyRaider Sense with Incredi kernel
KingX #6 scores almost 100 better than the next best in Quadrant. However, outside of that, I cannot really discern a major difference.
KingX seems to have the most significant changes in his changelog. Ziggy also seems to be brilliant, and yet, I really don't see any real differences between the kernels once implemented on my phone.
Can anyone help me isolate the differences -- perhaps I'm looking in the wrong place? I've basically tried to use everything I can think of, on the phone -- using each kernel, and tested all of them in power-save mode, tethered, etc.
Thanks in advance for any additional points to review..

quadrant is useless.
lou's kernels are great for me.
each phone is different so you'll have to test whichever one works best for you

Sure, of course. I'm familiar with the stock answer to the "which kernel is better" post.
That being said, I was asking something a bit different. I've *been* testing the kernels. The point of my post was to suggest that I cannot discern the difference after spending several hours with them.
With that in mind, I was asking if there is something specific I should be looking for, since I haven't found it (not with battery life, performance, or stability -- not with what I'm testing presently anyway).
Although, in addition to my original question -- of where to look to seek differences ... you do bring up another good point -- why is it that different phones (assuming they are the *same* model/android/radio version -- eg OLED 2.2's), would perform differently with identical kernels?

A few hours is not enough testing time for kernels. You need atleast a full charge down to 0 with a kernel to see how good the battery life is. Also, to judge the performance, you'll need a little more time for that too. Each phone is different. Some processors can take lesser voltages, high clocks than others. I'm not sure why this is, but it is. Honestly, I'm sure all the kernels are very good because the devs are excellent. But, some just work well for others while the same one doesn't for someone else. As I said before, just test out a kernel for a day or two, see how you like each one, and stay with it. If you battery life is being affected greatly, or your phone runs too hot or something, then switch to a different one.

At this point, I have more than 3 days or more on the following kernels:
* Redemptive with Lou's included kernel (3 days)
* SkyRaider Sense with KingX kernel (3 days)
* SkyRaider Sense with Ziggy's kernel (14 days)
* SkyRaider Sense with Stock kernel (22 days)
(Incredi -- I only had about 4 hours over two tests/loads and re-flashed, due to problems)
I've never run my batteries down to zero as you've mentioned. I've run them down to 10-20% on rare occasion.
In essence, what you are saying is that there really is nothing specific to keep an eye out for? If I don't see an obvious difference somewhere, there is no significant difference between the 4 kernels I have listed above? And Quadrant is of no help ... so in short, if they all get the same battery life, I just just pick one randomly?
I just want to believe there must be a more scientific/objective way of evaluating these kernels relative of each other.

if they are all pretty much the same to you, pick the one that makes you happy and that feels like it has the best performance and battery life. Maybe ask one of the devs about some scientific way of how each kernel is different from each other.

The problem is that I've built an app that our company uses over 18 phones that get run 9 hours a day, and the DInc's were overheating.
I went to Skyraider w/stock kernel, and that seemed to address the problem, at least it appears to reboot much less than the stock DInc's.
However, since I've made the commitment/risk of rooting/flashing these phones, I'd like to find some systematic method to determine which is the most efficient kernel to use, considering I have 18 phones in-the-field.
As a software engineer/empiricist, I'm not good at accepting the logic of "if it works, it's good enough". And so my objective is to find someone that may have some additional perspectives beyond that.
If there is a developer who sees this, I'd very much appreciate any information you can provide on how your kernel differs from others. Or someone who has some additional information.
Thank you in advance,
RKM

Hi! One thing that affects performance is SD Card Read Speeds. Ziggy and Incredi have an improved read speed, I just tested both and got 12mb/sec read with a class 4 card. Since HTC released FroYo Android 2.2 for our phone, they implemented a read speed limit of four MB/sec for the SD card. I just tested Lou and King and got read speeds of 4mb/sec from the SD card. All Fourkernels I got a write speed of 4 mb/sec.
Other major differences I think worth mentioning are that Ziggy includes a hosts file to block connections to advertising servers. But of course installing a different kernel leaves the new host file in place. Multi touch, I love the piano and playing games so this matters to me. Ziggy has had a 5 point multi touch enabled for some time. Lou & incredi have implemented in a different way. I am not the one to explain the differences. Lou turned it on for up to five multi touch points(but disabled it in his last build). Incredi had enabled all ten multi touch points but is now also at 5. Debugging. Lou disabled debugging so apps that rely on it will not work. Ex.... PDAnet. Lou did have wireless N disabled, he said he felt due to the minor network speed increase it was not worth the extra battery usage. But reading his change log I see it has since been re enabled.
Which one is best for you? It really does depend on too many factors to say outright. Depending on the apps you have installed, and apps you use the most. I listen to music a lot. Using one that lowers clock speed a bunchwhen the screen is off makes themusic skip. In theory you will get better battery life, but imo, its not worth sacrificing that usability.
Please correct me if I am wrong, mis informed, or steering peoples wrong. I hope this helps to understand some differences.
Overheating. It seems that the consensus is that the 9.01 radio works best for most people. Not me. The 9.01 version makes my phone get very hot. I use the 7.28 radio and it makes a big difference in my phone not getting hot.
What issues did you have with the incredi that made you have to abandon it so quickly?
~TheHoovie
Sent from my HTC Droid Incrediblel.
P.s. did you forget to include Chad/incredi in this threadstitle?

I've been wondering pretty much the same thing, and I have been reading the different changelogs from the respective kernels to find the differences between them. Thanks to you thehoovie for a good explaination, you put to light some things I have been wondering. Very good explaination!
With that said, what has worked best for me, is RR 2.1.3 with Ziggy's new kernel (BFS Jan 2 2011). I get great battery, I can control the freqs the proccessor is at all the way down to 128mhz, the system is very stable, and have had no problems what so ever. I get roughly 2 days out of a full charge with moderate use on a 1350 battery!

@TheHoovie -
Excellent, excellent information, thank you!
I did not include Incredi in the title, because I had problems with it (mentioned in first post). To answer your question, there were two things. One more subtle, that I don't remember off-hand -- and the other, was with downloading from the Internet. I had installed twice, on a SkyRaider ROM, and in both events, Incredi would hang when downloading.
I distribute all of our private, in-house software releases through our website. So not being able to download from the web in my testing .. was a deal killer!
Our users take roughly 900 photos a day, on average. Therefore, SD speed is extremely important, and I never would have tested the differences between kernels. This is exactly the type of feedback I was hoping to find -- in other words, I was not asking "which is best for me", but instead "can someone help me know where to look for differences in performance". Your comment on SD, is a perfect example of such a factor, thank you!
...Does anyone else have any suggestions, beyond SD performance and battery life, as to other factors for comparison/testing?
@m411b -
I cannot imagine getting two days on a 1350mah, this would be amazing! I'm running off to test your suggestion (RR + Ziggy's) now. Just one question: where do you set the CPU frequencies using that RR+Ziggy configuration?
EDIT: I just tested SkyRaider + Ziggy's #15, and it seems to be running very good. Ziggy's #15 also uses a low-power Bluetooth driver, which will be a huge help for us (we use BT to communicate between DInc's and gTablets in our app).
Thank you again for the great info!

One more related question...
Have people been moving away from these Sense ROM's to CM7/Gingerbread, and if so, any feedback on stability?
I keep reading about CM7 adoptions and it's starting to make me wonder if I should give the new Gingerbread version a try.
I have not tested CM since v6 about 45 days ago, but at that point, there were some issues on the DInc.

Suggestion:
1. turn off wifi.
2. turn on gps
Launch Last.fm or pandora - stream your favorite music station.
Launch navigation, Navigate somewhere.. (I actually do this.. I just use gps when I am out running errands for an hour or so)
See how long the following lasts:
1. Battery
2. Time without crashing
That's been my simple testing of kernels. This is not scientific.. its just real world testing IMO
I am currently playing with Lou's #4 vs #8 on the same rom.. I think testing on multiple roms would bring in more factors you cant control.
#4 crashes way too often when running navigation (its fine for day to day use though)

been using Lous #8 on SR3.5 and it blew me away with battery life as well as performance. I flashed #9 yesterday and am gonna give it a day or two before i judge it. I had previously used Chad's and Hydra. Chad's wasnt the best and hyrda was great for OC performance but not for battery life.

SGS2 ROM Shoot-out and comparison

Hi All
We have decided to build a comparative list of Rom for comparison. ROM's will be measured by the testers on 5 categories and hopefully we could get a honest opinion from the testers and not just a 5/5 for everything because they are a fanboy ...
ROM's will also be divided into 3 specific categories. Stock (Stock ROM provided from Samsung via update in Kies), Custom Original (Original ROM's by Dev's), Kitchen (Custom Original ROM's cooked and tweaked to perfection by a other Dev)
When providing us feedback on the ROM's please do so in the format below so we could add them to the corresponding list and add them to the graph that will follow in the 3rd Post.
Please try to be as Objective as possible. No point in having everything score 5/5

Well no one else will put in the effort so I will at least try. If there is any suggestions or fields that should be added please feel free to comment.
I will not personally flash to all the roms at all but will rely solely on user feedback to at least get a basic comparison going in the start.

I see..
I was hoping that detailed comparison could be made.
Like themer roms, kanger roms, original dev roms.
Not just ppl with no clue making comments...
for instance, when jkay releases, numerous rom cooks just packages the framework-re.apk (maybe with png changes), plus add whatever other apk mods others have done, add someone's kernel, zip it up and call it a their rom.
or worse, mix and match apks between other releases and call it their own
Special mention needs to be done to differentiate all this between the good guys and the others.
For example, look at what hyperdroid v6 has done.
Without waiting for jkay, incorporated 14 toggles, added edt/ tsm tweaks, and make it play nice with the Hyperdroidparts to control it all.
Adding their own brand new red pill recovery and kernel, and even sharing the recovery with syah for a community collaboration effort.
Multidpi also came from hyperdroid.., smooth spinners tweaks,
updates to vrtheme via surgeons etc.
EDIT: You might want to remove quadrant as that only kills the credibility of the thread.

Well that's the whole thing. I want to list them but only the main players. Not the mix and match ones cause there are literally hundreds of them and they are all the same in 90% of all aspects.
I am editing the 2nd post a lot so refresh on occasion to see if there is something new.
I think I will stick with what we have now in the listed comparisons. If anyone has anything to add feel free and I will just add it to the list of Items.

Anyway ... I think this is what the OP of that thread was looking for.

Sensation 2.0 rom with his own sexy theme...looks all great..and functions buttery smooth....maybe u can add in the list with other ROMS...

Lol ... I am actually trying to find some of the ROM's and cant even find the original threads as there are so many of them for different things.
If someone could link some of the ROM's we need to list or have listed it would be appreciated.

But there's still nothing useful in here, just some vague statement about battery life on a "stock ROM" "Battery Life: 2 Days Moderate use to 5 Days minimal Use" seriously? Or was this part a joke? And no actual mention of which stock ROM the few random statements referred to (besides 2.3.4, which must be pretty old).
I'm actually against the idea of a compilation thread . Sure you might think it'll remove some of the clutter from these forums and daily "best ROM" threads (in all honesty, it won't, the people starting those threads don't read stickies or search), but it'd be quickly outdated and be full of the usual "I think x ROM is best with y kernel because of z".
For a user to get an idea of current ROMs, all it requires is an opening of the development forum(s), pressing CTRL+f, typing [ROM] and ticking "Highlight all" in whatever browser is used. Read first post for changelog/screenshots and making up own mind.

Valid points. Thanks for the reply. I am using this stock rom but i should have probably added that I have the extended original 2000mah battery.
I do agree to some extent that it might get dated but when someone does a update or does review a new rom it takes 3 min to give your opinion and do a quick bench and just wrote everything down. I know it will take commitment from the community and obviously Dev's would want to boast with the Roms. There is no better way that a shootout for devs to actually go back and work on their rom to get better performance or less bugs ect ect.
Ultimately Users get better roms and there is a little bit of competition between the Devs for brag rights ofc
All in good sport I have to add.

since only the quadrant advice was taken, how are you going to differentiate the level of development by the rom makers?

Hi All
Seeing as this tread was motivated by some other trolls in a other thread I decided to take it upon myself to build a comparison list of Rom's out there and add their information to it.
This will ofc be a community effort to eliminate noob threads as some call it so for the last time share your collective knowledge and then you can refer all the noobs to this thread every single time.
If you feel the information in this topic is incorrect then please don't throw a hissy fit. Rather just correct it in a post and I will update the 1st post. If you want your rom to feature in this tread also reffer me to your roms page with all the relevant information so that I could find it there to update the tread with.
Please use the following template to Provide information for the ROM's being tested. This would help in getting them all together and tweaking them where needed.

I like the effort. Here are my suggestions
1) Categorize ROMS into AOSP, Stock and Mix and compare ROMS within their respective groups. Everyone knows the limitations that AOSP has at the moment.
2) Battery life is highly subjective, your findings might be considered flawed. Rather do a control test on each ROM with a few fixed apps/push/sync that almost everone uses. Post Battery usage and graph for each. You will also have to worry about screen on time.
3) Bench marks are again dependant on kernel, governor, scheduler (Please correct me if im wrong here, but i know that using VR gives better benchmark scores). Unless they are again maintained, a comparison would not prove any point.
Again, please do correct me I am incorrect anywhere.

I am actually very impressed with whats happening here.
Respect to all of you.

1. I could split it into the 3 groups and then categorize it accordingly. @s2d4 - would this help or do you think there should be better defined sections for them?
2. Agreed. There are a lot of variables that could make the test vary in results and it is very subjective. Could you give more detail as to what we should be seeing rather then Battery life.
3. If that is true we it could still be useful to the extent of determining if the rom is high in performance or rather a battery saver. I truly think if its the fastest out there it will consume the most battery doing so as well. Although that is subjective but could be relevant.

Thanks for the suggestions.
Sent a PM to toxicdust, hope the hatchet is well and truly buried (and not in anyone's cranial matter either...). But he's the boss - his idea AFAIC.
1 - Agree completely. I haven't and won't try any CM9/MIUI ROMs, and am not interested in ICS before an official release. Any help/reviews/feedback would be hugely appreciated here.
2 - Agree. Too subjective to bother with, IMO. Forgot to ask toxicdust about this. If you're there toxic, what do you think? Trouble with your suggestion is the subjectivity of "apps everyone uses". For example, I'm the only person on this planet who isn't on Facebook or Twitter, doesn't use Google Maps, and I don't use e-mail on my phone - I don't want to be available to all and sundry 24/7. I'm pretty sure I don't fit a "usual user" profile.. But hey! I'm special... Suggest a list of apps that you think the majority use, and we'll try to collate battery stats from there. Good?
3 - I want to drop benchmark scores completely. Individual use etc makes it too subjective for me, and the last thing a noob needs is seeing a score - "oooohhhh! 3045060604+3 on Quadrant! This must be the ROM for me, lolz"...
Keep the ideas coming.
Gotta swallow my pride - which I do gladly - and admit that this is a damn good idea - we've just got to do it properly.
I can't theme and I can't code - but this ensures I'm doing something for the community.
I can write though
OFF TOPIC
By the way - I've got no problem with the removal of many of my posts on this thread- would just like to know who's doing it?
I realise that I'm not owed an explanation, and I'm not asking for one either - this isn't a democracy, as I've posted myself at least 40606003 times.
I'm not sending a general PM to all mods, so can the mystery mod please PM me?
Once more, I'll stress that I have no problem with you guys deleting - just curious.
Thanks.

Kernel comparisons

I was wondering if anyone has done any actual testing between the different popular kernels available for the N4, or even a spread speed with a feature comparison.
With so man different options it hard to tell how they stack up, which have what fixes or what additions applied. I feel like someone should make a sticky that compares the kernels side by side so that newbies/people who are just not technical or great on following what has recently updated, can tell what each option offers.
I know that on the Nexus 7 forum there is a thread where a person applies the same device, ROM and settings to multiple kernels and test battery life in a few separate situations. I'd love to see someone do that for the Nexus 4 as well. I know there are many variables in play, but it can give people an idea of what each kernel provides.
That way people can more easily narrow down what kernels fit their needs/feature desires.

the problem is that different devices react differently to each kernel. one devices great, can be another devices horrible. i do understand your idea though, im not saying its bad, because it is a good idea. its just the results would be accurate(maybe, depends on how tested, for the tester. but could be very inaccurate for another device.

I know that, but at least a tracking spread sheet would be handy for comparisons, and the testing would let people know somewhat what what to expect.

What do you want the most out of a kernel? Battery life, speed, or oc?
I know im repeating another fellow member but not all chips are created equal. It all depends what kinda of use. You could try a kernel and run your tests on it. Then save pictures of the graphs if you can. Then flash a different kernel and make comparisons on them. A good place to start is Faux123 or Franco kernel. Both kernels are developed very well.

I don't think you are following me.
If you want to know what Kernels allow:
Color calibration
Ennhanced audio
built-in wifi fix
underclock to 192mhz
Would you rather read 12-15 threads or just look at a spreadsheet in a sticky on top of the forum, and know what 2-3 to choose from instead of reading all the descriptions and notes?

Just try some kernel`s out and keep the one you like most, is this again one of those disguised `best of` threads? Each user has a different setup (apps, widgets, syncing, roms, mods) so this would not be a test under similar conditions.

When I chose a kernel, I used to manually look through each kernel thread and then just try the kernel myself. Didn't need any fancy spreadsheet or comparison charts.
Plus I have a feeling it would... deter newer kernel developers and misguide newer users. A user sees "X" kernel not having a feature, when 5 other kernels have every feature, and they'll skip right over that kernel, regardless of what benefits it may offer.

If the kernel has benefits then they would just be listed. You're example doesn't make much sense to me, if a person wants a feature, they yes, they will use a kernel that has that feature. If a person wants to tune the color on their screen why would they NOT get a kernel with that control feature?

a few good kernels dont list "features". and some kernels make up names for features to make them sound more then they are, and make it a point to list "features" that really arent. really, its best to try a kernel, as these "feature" lists can be very misleading.

Better Battery Life Tips :
Disable GPS, 3G, Wifi, Sync when not in use
Disable auto sync of Google and / or other accounts
Set brightness level to automatic or minimum
Disable auto rotation
Close / disable useless background apps
*Also try Greenify from the app store, for more free ram and battery saving*
**THIS IS NOT MY WORK, SO REMEMBER TO THANK THE DEVELOPERS**

YOUR REVIEWS ARE IMPORTANT TO US ! ! !​
This is an amazing community of NS die-hards that are constantly looking for the best ways to keep the phone alive.
We need your input on ROMS, KERNELS, APPS, MODS and TWEAKS that can help improve our phone. As well
as tips on what doesn't work or what not to do.
If you try a rom,kernel,app,mod,tweak, please give your experience with it.
START WITH IT'S NAME AND DEVELOPER (LINKS ARE ALSO WELCOMED)
1. Performance
2. Battery life
3. Bugs or other issues
4. Favorite feature(s)
5. How you had it set up (cpu speeds, ect..)
6. Feel free to add any other relevant information
7. Would you recommend it
And remember, that these are opinions, be curtious, use the thanks button and ALWAYS thank your developers.​

Okay, this is a bit of script that is a revised version of Killjoy using some input from Supremacy along with anything else shiny that I had to pick up..
-This cannot be used with any other tweak/mod of this nature
-This should only be flashed on a clean install of a rom (minus any mods/tweaks)
-This modifies your build.prop (any other mods may cause undesired effects)
-I suggest rebooting after installation and entering codes into the terminal emulator
-If coming from the original Killjoy or one of my versions, do an uninstall of previous version before installing
Use the Operation Killjoy thread to turn on/ off features as the rest of the modified script works without terminal commands..
THIS IS NOT MY WORK
DO NOT COMPLAIN TO THE ORIGINAL DEVELOPERS WITH ISSUES AS THIS IS A MODIFICATION OF THEIR ORIGINAL DESIGN
DO NOT USE THIS TO TAKE OVER THE WORLD (unless I get free cookies)
I do not take responsibility in any issues you or your phone have before or after flashing, nor for world hunger..
FLASH AT YOUR OWN RISK!!

All rom's are great, but for different reasons.. I would hope that the comparison doesn't diminish from the developers work, but allow for a better idea of what a rom offers.

Which is the best DPI value in your opinion? Slim for example uses very low DPI value but it is still nice. What is the advantages and the disadvantages of using low DPI?

I use the stock 240 that most custom rom's use, other than issues with apps in the Playstore, I see no advantage nor disadvantage to dpi. It is helpful to lower it if you like having dual panels, but I like to be able to read the already small text on my screen and with my aging eyes there is no need to make it smaller..

Your (or anyone's) ROM review cannot be the absolute truth.
Truth #1: Custom ROM performance, stability, and overall smoothness are highly dependent on how a person prefers to use his particular device on a day-to-day basis.
Truth #2: The stability of a Custom ROM is entirely based on how a person uses the rom's features & system apps, and what kind of 3rd party apps s/he installs and uses the most. Apps found in the google playstore are mainly optimized for Official Android ROM's stability.
To further give users basis on how you do your rom reviews/guides:
1. What apps did you install and uninstall when you flashed the rom?
2. How old is your device?
3. What apps do you use most often? (including system apps)
4. What custom rom features do you use, and how often do you use them?
5. Why won't you use certain features, and what certain features causes instabilities and/or performance drops on certain ROM/s?
6. How long do you test the ROM before you make a conclusion with regards to its speed, smoothness, features, stability, and battery life?
You are not obliged to answer. This is your thread after all
ps. Mirage rom is created by des-franco. People might confuse this with franciscofranco.

"YOU WANT THE TRUTH,.. YOU CAN'T HANDLE THE TRUTH"... I may be too old for everyone to catch that reference..?
Phew, you made a list..
1. I let Google auto-update my rom(s) with my 100+ apps (too many to list)
2. My device is roughly 2 yrs old (but don't tell it how old it is, it's sensitive)
3. I use FB, Gmail, Yahoo, XDA, Youtube, ect... Some minor games and french lessons (as I should be practicing that instead of this... lol)
4. I use all of them to test, but I don't use most of them as daily drivers as I have no use in some of the features..
5. I think that certain features like Xposed framework and PA settings rob performance and are unstable.. I also don't like to run overclocked. Some rom's/ kernels can handle these features, but I find them pointless.
6. Two battery cycles.. The first is to install/test if it will be buggy, the other is to see how well it holds up to my normal day to day..
And I admit that my reviews are based on one phone (as all phones can vary) and personal usage that is subject to bias and change..

SlimBean 3.1, HellyBean, CM 10 (which you already have), and other popular ones. Particularly because I am trying to find a good 4.1.2 ROM that is smooth and has great battery life. Currently on Slimbean with marmite, and I'm not liking the battery life (Usually get around 20% screen time usage which is on for 1-1.5 hours only)
Edit: SlimBean 3.1 - it is PACKED with features, 10/10 on that (I have everything I could possibly want). Performance is really great too, little lag sometimes only. The only downside is the battery life as I stated above.

just to say that with my device and with my user experience on the roms you've tested: i agree with a lot of what you say in your rom guide!
nice work!

I ran Hellybean 4.1.2 for about two weeks and it was great, I did change kernels on it and increased battery life immensely.. Have you tried the newest Marmite with your Slim rom, it should be compatible and would help your battery life.. Also try Greenify and hibernate all your apps minus the launcher and greenify itself.. you will see an improvement.. I also would suggest to limit the apps that want to auto sync and shut down google maps unless you are using it..

Hey setting out, I'm pretty sure that rasbean jelly is 4.2.2 now. Rusty
Jay has been updating it recently

much needed thread
thank you very much OP
this is a much needed thread. i think all devices should have a thread like this.
its very useful to people new to a certain device and to those like me who dont have the time to test all roms available.
i have tested slim and thinkbridge extensively and gamerz, cm, xylon only for short time. settled with slim because it had best battery life in my device and was devoid of unnecessary stuff i wouldnt use.
i think you can expand your comparison to include some prominent/differentiating/special feature of each rom. it would be easier for the readers to get better idea about which rom would fit his/hers needs. for example, i like slim because,
1. i like the "dark slim"
2. it doesnt have all the wall papers or live wall papers that i wouldnt have used anyway, thus, freeing more memory.
thanks. keep up the good work.

[Updated 11-Dec-2018][oxygen] Battery Life / Performance Benchmarks - AOSP Roms

[22-Nov] NEW: ArrowOS v8 with alternative cpu governors. Check it out in post #127.
Here is my first series of PC Mark Battery Life Benchmarks for the Xiaomi Mi Max 2.
Let me first say that this is not a "best rom" thread. There is no absolute best rom. What is best for one user may not be best for another. To give a simple example, battery life is very important for some users while performance is priority for others.
Benchmark results are usually misleading, but PC Mark battery life benchmark shines by using day to day tasks to measure phone performance and battery drain. It repeats for many hours, until battery drops below 20%, a series of tasks including web browsing, photo and video editing, text editing and data manipulation. Then it extrapolates the SOT that would be obtained with 95% of the battery charge.
For each rom I made a clean install and a simple setup with basic settings and a added a few apps necessary to monitor/admin the runs.
The tests are run with the screen brightness calibrated at 200 lumens as required by PC Mark and all sound levels set to zero, so results are better suited for comparison.
Each benchmark run takes between 9 and 11 hours. So this test is also a stability test. Some rom/kernel combinations simply fail to complete the benchmark.
If you want to learn more about PC Mark take a look at the site: PC Mark for Android.
These are the roms included so far:
AospExtended-v4.6-oxygen-20180425-0949-UNOFFICIAL by @eva0034 - [ROM][7.1.2_r29][UNOFFICIAL] AospExtended ROM V4.6 [OMS/DUI]

Lineage 14.1 (30.10.2017) by @xuefer - LineageOS 14.1 for MI MAX 2 (oxygen)
XenonHD-180329-Unofficial-oxygen by @Jay_B - [UNOFFICIAL] XenonHD_Oxygen 7.1.2 With Substratum Support Final
RR-N-v5.8.5-20180412-oxygen-Unofficial by @iscle - [ROM][FINAL][7.1.2][2018-04-12] ResurrectionRemix 5.8.5 [UNOFFICIAL]
RR-N-v5.8.5-20180321-oxygen-Unofficial by @kenzolo - [21March][ROM][UNOFFICIAL] Resurrection Remix v5.8.5 [7.1.2][Nougat]
Some might be wondering why it took so long for me to add first results.
I have already run literally hundreds of benchmarks, mainly for the Samsung Galaxy Note 3 and the Xiaomi Redmi Note 4. I had very few situations where a benchmark would not finish.
With the Mi Max 2 I had to spend almost a month testing a few roms and modifying my test environment so that a benchmark would finish. It was happening with every rom I tried. Very frustrating.
Eventually I reduced the number of apps I use during tests from 22 to 8 and was able to start completing benchmarks. Failures still happen, but now at least I have an around 60% success rate.
I added a line with the number of failures for each rom in my results table. Keep in mind that failing the benchmark does not indicate that the rom is unstable and not suited to be a daily driver. These roms may never fail in normal day to day use.
I also noticed that battery SOT varied a lot between my two Mi Max 2, so I had to give up using both. All tests were run on the same phone.
Anyway now, even with only one phone, progress will be faster.
Enough talk. Now Let's see the results:
{

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Score is a performance index - the higher the better.
SOT (Screen On Time) is an estimate of the number of hours the device may be used until battery drops almost dead (from 100% to 5%). It's a very good estimate because the test starts with the battery at 80% and ends when the battery drops below 20%.
There is no clear advantage comparing the roms tested so far. They all offer similar performance and battery drain.
So any of these roms will serve you well and you should pick one based mainly on features you want the most.
11-Jun-2018 Update:
Added three more roms to the results table.
I was so wrong when I predicted next results would come faster.
Lost about 10 day trying every possible way to benchmark ashwin´s LA15.1, but benchmarks would simply not finish.
Also had big variances between runs for Jay_B´s XenonHD and iscle´s RR-N. So I ran extra benchmarks to have more meaningful averages.
With more Oreo roms showing up my plan is to focus on Oreo roms for the next benchmarks.

I use PC Mark for Android - Battery Life Benchmark.
Benchmark results are usually misleading, but PC Mark battery life benchmark shines by using day to day tasks to measure phone performance and battery drain. It repeats a series of tasks including web browsing, photo and video editing, text editing and data manipulation.
I am predicting each test run on the Mi Max 2 will take 10-12 hours. During all time the phone has to remain untouched. Receiving a call or SMS makes the test stop.
For more info take a look at their site: PC Mark for Android.

I am a little paranoid with the benchmarks. I try my best to have comparable results by doing the following:
- Clean install the rom
- Install always the same 20 apps, mainly support utilities, using Titanium Backup to restore them
- Use the same basic settings (no optimizations - no kernel tweaks)
- Sound always set to zero
- Brightness always set to 200 lx using the same meter (as required by PC Mark)
- All auto brightness settings disabled
- Wifi on and always connected to the same router
- Bluetooth always on but not connected to any device
- Location set to High Accuracy
- Benchmark always start with battery at 80%
- Reboot phone before each test
- Phone stays still always in the same place in my home office

Nice to know that my name is mentioned there.
You are doing great work on that OP, keep it up.
And yes, i have slowed down for now.

And what is the meaning of these synthetic tests? They do not give information in full. There are so many other factors. I know 3 Roms, where there are problems with voice communication. On 2 other "departing" applications. Sense in such tests? For example, we see one of the highest scores in these tests. But there will be problems with communication and other things. What is the point then? Only because of the greatest number of points in the test? For daily use, they are not suitable. Everyone has their own personal preferences. I tested all the roms for this device. For me personally, the best of them - crDroid and AOSP Extended from pranavaryans. Now I use AOSP Extended from pranavaryans
Excellent rum. But why is it not in the survey. All this is my personal opinion. Personally for me, such a waste of time. Everyone is very individual. The test is just numbers. They do not give complete information.
But ... maybe someone will be interested. Good luck

this thread isnt supposed to be an "end all discussion" solution concerning the "best" rom. u said it yourself, everyone has their own personal preferences! so what if someone doesnt care about those "departing apps" because hes using different apps, but really cares about cpu / gpu performance due to gaming?
this data doesnt give you an excuse not to do your due diligence, so ALWAYS read the respective rom threads to find out what kind of bugs / functionality they have.
BUT
it helps you make a more informed choice when, say, youre stuck between 2-3 roms which might be very similar in mods and functionality / design. having more information at your disposal is always good, so this is far from being a "waste of time"
I dont get this negative vibe from a lot of users here. trying to shoot down threads, discourage devs or criticize projects such like this which take a LOT of time and work for their initiators to complete. And all that because "they personally" are not interested in it and think its "a waste of time"? Well guess what: not everyone shares your opinion / your everyday usage cases / your preferences concerning ROMs, Apps, settings, design choices, etc. And thats totally fine! Everyone has different requirements, so lets just collect all the info we can so that everyone can make his/her own choice.
What would you get if everything was shut down just because we have different requirements? Well then there wouldnt be ANY choices left. Congratz, youve just made XDA superfluous

this thread isnt supposed to be an "end all discussion" solution concerning the "best" rom. u said it yourself, everyone has their own personal preferences! so what if someone doesnt care about those "departing apps" because hes using different apps, but really cares about cpu / gpu performance due to gaming?
this data doesnt give you an excuse not to do your due diligence, so ALWAYS read the respective rom threads to find out what kind of bugs / functionality they have.

You misunderstood what I wanted to say. I'm not against flows, quite the opposite. I expressed only a personal opinion about such tests. If it helps someone, that's fine. The results of daily use will differ from the test results. That's what I wanted to say

yes, totally agree on that. battery life is extremely dependant on personal usage cases. still, since your own usage pattern basically stays the same no matter which rom ure using, it makes sense to compare the roms with one and the same strategy.
lets say testing shows that ROM A provides 2h more SOT than ROM B, with a total of 14h SOT on A vs. 12h SOT on B.
With your usage pattern you might only get 10h SOT on ROM A due to heavy usage of GPS and LTE mobile data. Still, due to overall higher system energy consumption on ROM B, you know based on the given testing data above that your own usage pattern will most likely net less SOT on ROM B than on ROM A. So in your case, you already know that you might get 8h SOT on ROM B just by looking at the 14h vs. 12h data from testing

When you start to test roms?did you wait for specific vote number?I'm just doesn't unlock my device because of your test
I'm waiting to see the results then compare them to stock miui and then decide what to do because I can't see the big devlepors(with respect to all of them) or teams for this device(like leedroid or viper or eliminator purefusion for htc)
So I make a choice totally base on your tests
Thank you so much for your time spending for community

i can tell you right now that it will not make sense for you to wait for his tests to be complete this will take weeks if not months, i doubt ull wait that long

I thought he starts soon(for example this week or next) and test roms with some scripts and then test another one
So I thought test will take at most two weeks
Am I wrong?he doesn't use script for test?or benchmark app?like gsmarena or others

And what is the meaning of these synthetic tests? They do not give information in full. There are so many other factors. I know 3 Roms, where there are problems with voice communication. On 2 other "departing" applications. Sense in such tests? For example, we see one of the highest scores in these tests. But there will be problems with communication and other things. What is the point then? Only because of the greatest number of points in the test? For daily use, they are not suitable. Everyone has their own personal preferences. I tested all the roms for this device. For me personally, the best of them - crDroid and AOSP Extended from pranavaryans. Now I use AOSP Extended from pranavaryans
Excellent rum. But why is it not in the survey. All this is my personal opinion. Personally for me, such a waste of time. Everyone is very individual. The test is just numbers. They do not give complete information.
But ... maybe someone will be interested. Good luck

Yes, benchmarks are misleading most of the times. I never liked benchmarks myself. Real life usage is affected by so many factors.
But PC Mark Battery Life is not the usual benchmark. You should visit their site to better understand what it does.
PC Mark for Androd - A Better Benchmark for Android Devices
In a few words, this benchmark runs a series of simulations of day-to-day tasks , including web browsing, video watching, text writing and photo editing. The series is repeated until the battery drops below 20% and then you get an extrapolated SOT and a performance index.
I start the test with the battery precisely at 80%, so it uses about 60% of the battery charge, and the extrapolated SOT is very meaningful. The phone has to remain still during all time. If you run any app or receive a call/SMS while the benchmark is running, PC Mark simply aborts the test.
Since the benchmark runs for hours it is also a stability test. If the rom has, for example, memory leaks, it fails the test. I had it happening a few times with the two other devices I tested.
I truly believe my work produces useful info to help users make a more educated rom choice.
Of course there are many other important points that should be checked when choosing a custom rom, like customization features, active development/support, user base, etc... and the info I provide should never be the only basis for a decision.

Tests will start this weekend. I am having an unusualy tough work week, with long hours.
The votes will only help me defining a test sequence and have a feeling of how much people are really interested.
Running these benchmarks is a very time consuming task. The phones remain unusable for days/weeks.
The more people interested, the more motivation I have to keep benchmarking roms and kernels (yes, kernels eventually will appear for the Mi Max 2).
Right now I am benchmarking all important kernels for the mido (Redmi Note 4). There are 10+ kernels available.
The Mi Max 2 will be the third device I run benchmarks.
It all started for my main device, the venerable Samsung Galaxy Note 3, because its SOT is usually 3-4 hours, and battery life is a really important factor when choosing a rom. For the Note 3 I made a few scattered XDA posts. No dedicated thread.
Then I got my midos and decided to open a thread for my benchmarks. It was very welcome by the mido community, including developers, because the results helped them adjusting roms to better achieve their goals.
Now here I am with two Mi Max 2. Let´s see how it goes....
