Do you happen to keep any Alexey's RR Nougat build? Can you share it on a mirror (e.g. Google Drive) with us? Download page in OP is dead, and I cannot find any other download link. Alexey's profile on AFH only contains Oreo builds.

[EDIT] Nevermind, found it!!

[Xiaomi Redmi Note 4 Guides, News, & Discussion] svbarbosa:
This may be the last preview. I am almost done!

Newly added kernels are Stormguard 5.0 and Velvet r6.7:

Right now I am benchmarking FrancoKernel r6.

Next Kernels will be Kudkernel latest build and Velvet newer build or test build, if there is no new official build when I get there. :p

Doing it right now. :cowboy:

Unfortunately Weeb failed to complete the test. If a new build comes I will try it again.
[Xiaomi Redmi Note 4 Guides, News, & Discussion] thapaavijeet:
Greatly appreciate you work.

It is not long before we start seeing the Oreos beat the Nougats in terms of battery life.

Check my phone's stats and they are during the use of mobile data and not Wi-Fi. (Those breaks are due to me restarting the phone)

I want to download in this link Stock/RRN - Alexey71's AFH.. but the link can't be found... Can u give me the available link.. please..
[Xiaomi Redmi Note 4 Guides, News, & Discussion] NTLinhHaHa:
I attached his link earlier. Try 1-2 previous pages of this thread, find my comment.
[Xiaomi Redmi Note 4 Guides, News, & Discussion] svbarbosa:
All Alexey´s RR builds are in his SourceForge. Link is in the OP, first line in rom list.

Noted, but next series will be for Treble roms.
[Xiaomi Redmi Note 4 Guides, News, & Discussion] NTLinhHaHa:
If you ever edit OP, please edit the link into this link. Your link eventually led to his sourceforge, but it gave an error because it led to a deleted folder on his repo.
[Xiaomi Redmi Note 4 Guides, News, & Discussion] svbarbosa:
Alexey has changed the folder name. Now the OP is pointing to his root folder as per your suggestion.

Thanks. :good:

Franco Kernel looks rather disappointing to me, although Franco claims that his kernel has "legendary battery life". Comparing to the other kernels - even stock Rom kernel performs better - it doesnt look so "legendary" anymore.

I used to use Franco, but will revert to stock as soon as LOS 15.1 becomes official.
[Xiaomi Redmi Note 4 Guides, News, & Discussion] razibrizal:
disable touchboost and it will save more battery, i too disable touchboost when using franco kernel
[Xiaomi Redmi Note 4 Guides, News, & Discussion] kira1011:
Where is it?
[Xiaomi Redmi Note 4 Guides, News, & Discussion] EvilMegaDroid:
You do understand that this benchmark test's device with screen on all time? Franco is definitly one of the best in term of battery life if the user knows what he's doing and don't fkes up the kernel settings.
[Xiaomi Redmi Note 4 Guides, News, & Discussion] svbarbosa:
Finally this kernel series is done!! :D

I will have to rework the OP. :p

In the meantime here are the final results:

Newly added kernels are FrancoKernel r6 and KudKernel r17.

Two kernels failed the benchmark: Weeb and Velvet t6.8 (test build - so it is no surprise it fails).

Next benchmark series will be treble roms. I am already benchmarking EndLess's RRO treble build.

To give easier comparison (or for people that prefer one over the other), here are the kernels sorted by score:

Here are the kernels sorted by SOT:

And here's a list giving the combined best result (SOT times SCORE):
[Xiaomi Redmi Note 4 Guides, News, & Discussion] svbarbosa:
Thanks for the tables.

What a coincidence, I am also working on a similar summary.

First I had to normalize the SOT/Performance scores and then took into considerations the standard deviations, because the higher they are the less stable the result you get from day to day.

My compound rank is similar to yours.

I should already have posted my table but real life responsibilities are taking almost all my time. :p

Hopefully I will post it before Sunday.

[MENTION=3342533]svbarbosa[/MENTION] Your contribution to mido community is immeasurable. Thank you for giving your precious time and efforts.

I just wanted to throw some light on reduction of li-ion battery capacity over increasing number of charge cycles.

Judging by your data on battery test i can fairly conclude that your device's battery has undergone pretty hefty number of charge cycles, even when you have two devices. This would decrease the SOT of the phone by some amount. and continuing this might even produce more inaccurate results.So i would like to propose a new alternative which utilizes voluntary people to use your method of evaluation on their mido and sending the results over to you for compilation and results. This method also has flaws because you cant ensure every volunteer to have same battery capacity which can be eliminated by taking avg of multiple data on same Rom/kernel.

This would speed up the process , give fairly accurate results and distribute your workload among other contributors.

Again thanks for your hardwork. REally appretiate it.
[Xiaomi Redmi Note 4 Guides, News, & Discussion] runeupo:
Yes you're right, but small time.

Assume 50 cycles of charging to 85%. But from 20%, see

post #4

, so it's 65%-cycle

Read this one:

http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries

Figure 1 Decrease of 10-15% capacity @ 250 cycles (full 100% cycles)

Well, I'm no mathematician or number wizard. So although you're right, I think you're just small time right, the mere ~1 percent of lesser battery capacity shouldn't influence overall scores significantly.

Anyway, back to real life issues here :)

Hint for your own battery : I'm using magic charging switch, it's a magisk module developed by VR25, to increase overall battery life

[Xiaomi Redmi Note 4 Guides, News, & Discussion] iKrautDroid:
I also have to express my thanks to [MENTION=3342533]svbarbosa[/MENTION], this whole project has been incredibly helpful.

If I may, I would suggest one more benchmark run: Test a high scoring kernel (such as Velvet, etc.) together with an official build of Resurrection Remix instead of the EndLess build.

I believe this would be useful as it would let us see how much of a difference the modifications made by rom builders really make vs. the fact that they just include a different kernel.

Using the same kernel would remove this variable and show us the merits of each rom.

Tl;dr: Official RR with Velvet kernel vs. EndLess RR with Velvet kernel
[Xiaomi Redmi Note 4 Guides, News, & Discussion] svbarbosa:
Yes, the battery wear is negligible, specially because, since the kernel benchmarks, I am starting PC Mark with the battery exactly at 80%.

I use the following app to stop charging at 80%:

[APP][ROOT][4.0+]Battery Charge Limit

.

Anyway, if anyone wants to post benchmark results that are comparable to mine, try to follow closely these requirements:

- Clean install the rom

- Do not install any apps unnecessary for the test, specially apps that run in background

- Use rom basic settings (no optimizations - no kernel tweaks)

- Set sound levels to zero

- Set brightness to 200 lx using a light meter (as required by PC Mark)

- Disable all auto brightness settings

- Wifi always on and connected with internet available

- Bluetooth always on but not connected

- Set Location to High Accuracy

- Benchmark always start with battery at 80%

- Reboot phone before each test

- Install Global Developer firmware (I usually update firmware before each series - never in the middle of a series)

- Phone has to stay still in the same place during test

- Phone has to be fairly new, with a battery that did not suffer many charging recycles

I know. It is a lot. :p

A normal test run takes about 7-9 hours, then one hour to recharge the battery to run next test. :p :p

And remember that the phone can not be used while the test is running. Even an unanswered incoming call aborts the test. :p :p :p

Interesting idea. This may be my next series after the treble roms series is done. :good:
[Xiaomi Redmi Note 4 Guides, News, & Discussion] Mahdigh08:
Thanks for your hard work, is it possible to add one or two official stock rom, such as miui 8.2.10 and miui 9.5.8 to compare custom rom to them
[Xiaomi Redmi Note 4 Guides, News, & Discussion] jayjaymowmow:
So what is the best kernel for you?
[Xiaomi Redmi Note 4 Guides, News, & Discussion] svbarbosa:
I did some math work with the kernel series results to produce more meaningful rankings.

First I produced a normalized score for SOT and performance.

To translate the math into words, the normalization takes the score average to correspond to a 1000 score value. So if a kernel score is exactly the average its normalized score will be 1000. If a kernel normalized score is 1100 this means this kernel score is 10% above average. If its score is 10% below average its normalized score is 900.

I also took into consideration the standard deviation. This number represents the kernel stability. If the deviation is zero, then every time you run the benchmark the outcome is the same. What I did was to take the standard deviation percentage and reduce the normalized score by this percentage as a penalty. So if a kernel standard deviation is 1% and it normalized score was 1000. The adjusted normalized score becomes 990.

Then I produced three rank tables with averages of the normalized SOT and Performance scores:

- One for those who are looking for a balance of SOT and performance, with the final score as a simple average of normalized SOT and performance scores.

- One for those who favor battery over performance, with a weighted average of the normalized SOT score times 2 and the normalized performance score.

- One for those who want performance, even with some SOT sacrifice, with a weighted average of the normalized performance score times 2 and the normalized SOT score.

In all three tables you will have the normalized SOT and Performance scores and a simple rank for each normalized score.

Here are the tables. A few comments will follow.

Simple SOT/Performance Average​

Battery Weighted Average​

Performance Weighted Average​

The real winner is Inferno kernel, with a fantastic balance of battery and performance. It tops the three tables!

Stock kernel gets two fourth positions and a fifth position. As expected its performance is average in all cases, which is good.

The legendary battery performance of Franco kernel is not so legendary here. Its performance is better than its SOT. Anyway it is a great choice. I see its r6 build as the second best kernel in this series.

And, for those who value SOT above everything else, Velvet is the choice. The only one to reach a 12 hours SOT. The downside is the worst performance score in the series. Still its performance is a little less than 10% of average performance. Not so bad. And Velvet is the oldest build tested here. I tried its test build but it would not complete the benchmark. Probably a new build will be released soon and it should improve scores, as happened with Franco and Kud.

A final word is that all scores are not that far apart. So the truth is any of these kernels will serve you well.

All kernel benchmark results are in

[Xiaomi Redmi Note 4 Guides, News, & Discussion] JosVermeulen:
I've noticed benchmarks and real life have quite a difference. ZPX looked very promising so I tried it, but for now it seems to do worse than FK r6 if you're a light user. I'll test ZPX for a week to see if anything changes, but it's not unthinkable to have benchmarks give another story than real life. For heavy users it will probably be more correct.
[Xiaomi Redmi Note 4 Guides, News, & Discussion] razibrizal:
try kudkernel, better for battery
[Xiaomi Redmi Note 4 Guides, News, & Discussion] svbarbosa:
I am already working on the "Treble ROMs Series"

Will post first preview maybe tomorrow.

So far I have done:

- RRO EndLess 2018-0513

- LA 15.1 Extended Alexey 2018-0515

- Cardinal 2018-0519

- RRO Official 2018-0514

Next will be crDroid.

There is still time to make suggestions. :)

I may go back to benchmark newer builds of some kernels. As always no promises. :p

The truth is each user has a different usage pattern and actual results may vary to a great extent.

Out of curiosity, when you say ZPX seems worse than FK, you mean in terms of performance or battery drain?
[Xiaomi Redmi Note 4 Guides, News, & Discussion] svnhvn:
Yes, i felt the same way. Not only for light using, even for gaming.

Please do AEX too. For me, ZPX feel a bit laggy and often throttling. Overall my experience with ZPX not quite as fun with FK. Not to mention ZPX makes GCam (on my device) crashed, in every versions.
[Xiaomi Redmi Note 4 Guides, News, & Discussion] anon1135:
he probably meant battery that is what I noticed when I tried zpx. it felt about the same as fk or slightly better outside of games at the cost of some battery, during games it was noticeably smoother.

if a user was someone who doesn't play games at all, imo it felt like fk would have noticeably better battery to them with about the same performance.

another kernel i tried but didn't give much of a chance yet and might get back to is kud. performance on it didn't seem as smooth as fk though I'm hearing battery on it is better so its probably more of an all battery kernel. I guess it comes down to which kind of balance is preferred between performance, battery or both

---------- Post added at 03:51 AM ---------- Previous post was at 03:48 AM ----------

u should try serjo version of gcam with settings shared by zile its great no crashes and also improves low light shots. best I tried so far on fk no bugs yet but maybe some can show up later. not sure how it will work on zpx though
[Xiaomi Redmi Note 4 Guides, News, & Discussion] Zile995:
If you modify ZPX settings in AROMA, then gcam will crash. Use default settings.

Also i think that ZPX modifies system partition (changing thermal config).
[Xiaomi Redmi Note 4 Guides, News, & Discussion] kira1011:
Btw if you really gonna bench new kernel, I hope you wait until revolt 30 out.it will be out soon after more test is done.that way no kernel miss the game. Well it your call.just suggestion. Thank your for you contribution for mido community
[Xiaomi Redmi Note 4 Guides, News, & Discussion] JosVermeulen:
Battery drain by the looks of it. I regularly get 3-4 days of usage per charging cycle as I'm a light user. But I'm testing ZPX for at least a week to give it a fair chance.
[Xiaomi Redmi Note 4 Guides, News, & Discussion] Hammad1029:
Is abishek's Lineage OS in the queue? If so, how far down the line? I'd like to know because, after 3 months of buying the phone, i need to finally settle down and setup one ROM completely :)
[Xiaomi Redmi Note 4 Guides, News, & Discussion] thapaavijeet:
Could you check whether the governor is set to interactive or performance. The benchmarks by [MENTION=3342533]svbarbosa[/MENTION] appear to have done on interactive. However, when I flash ZPX with the default settings or by using custom ones through aroma, the settings don't seem to persist and I end up with the performance governor by default. This is not only limited to the governor selection and tunables but to others like CPU scheduler parameters as well. If this is the case then this kernel would not perform as expected.
[Xiaomi Redmi Note 4 Guides, News, & Discussion] JosVermeulen:
It's on interactive for me. Always has been, as I haven't noticed any governor profile jumps.
[Xiaomi Redmi Note 4 Guides, News, & Discussion] svnhvn:

Which is best rom to try with zpx kernel

And which version is good 1.8 or recently added 1.9

And on which android 7.0 or oreo if oreo then treble or non treble?
[Xiaomi Redmi Note 4 Guides, News, & Discussion] talhamk58:
Alexey's Lineage Extended treble.

Been using Alexey for 3 days now. I would say I'm a moderate to heavy user and I got great battery life. I also used around half hour of hotspot which I think consumed around 4-5%. LTE on for all day except 7 hours I sleep and brightness 50% @ auto. I used the balance profile in the performance app by Alexey (I use the same settings for all ROM just to be clear). Also the ROM has just enough customizations not to be cluttered atleast for me.
[Xiaomi Redmi Note 4 Guides, News, & Discussion] iKrautDroid:
Does Alexey's Rom have all the Resurrection Remix features, or is it more like LineageOS?
[Xiaomi Redmi Note 4 Guides, News, & Discussion] razibrizal:

[Xiaomi Redmi Note 4 Guides, News, & Discussion] InfectedMushROM:
As the post above you said, it has just enough not to be cluttered like RR, which was the reason I dislike it. Lineage on the other hand is quite bare feature-wise. I really like Lineage's Privacy Guard though, so Alexey's ROM hits a sweet balance, at least for me. He also adds new stuff almost daily. Look at the change log for yourself.
[Xiaomi Redmi Note 4 Guides, News, & Discussion] svbarbosa:
Time for the second preview of the Oreo Treble Roms Series:

Note that I removed the CPU Governor / Hotplug information from my tables.

For our mido all roms / kernels I have benchmarked so far have exactly the same settings: Interactive CPU governor and MSM Performance hotplug.

I added the Android Security Patch Level and the Selinux Mode in their place. I believe this is more useful, but Security Patch is the same in all roms. :p

Next in bench is LineageOS 15.1 Official.
