Give BubbleWrap HMP kernel a try, flash it, then download Spectrum app from store, it lets you control battery saving/performance with presets

---------- Post added at 03:52 PM ---------- Previous post was at 03:51 PM ----------

I tried nameless kernel too yesterday, device was too slow, i switched to bubblewrap hmp kernel and everything is going smooth on balance preset
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] mcalistri:
Don't know how eventually proceed to use MTweaks, in any case my observation is not related to speed up notification but the starting of apps which are more "RAM hungry", as Facebook, Twitter, WhatsApp and LinkedIn, wherein when you click on one of these you need to wait some seconds before be able to use the app, which is being loaded noticeably more slowly than when you use default kernel.

Did you tested F1XY kernel?

If I don't remember wrong, it was one of the first EAS kernel I saw around.

(Don't know if I wrote the name correctly nor if it is available for 4.4 kernel)

Honestly I don't like current EAS 4.4 Nameless snapshot I flashed, it is too slow IMHO. I would like to find a more balanced kernel among snappiness and battery duration.

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Dokken2x:
I haven't tested F1XY, and I don't plan to, its been discontinued I think. I'm happy with BubbleWrap HMP kernel, its smooth and has spectrum support too. You should try it.

I'm on AEX 6.6 + bubblewrap kernel, every time I reboot my phone my screen settings (hue, saturation, contrast...) are not applied, so i have to manually adjust them every time, is this normal? any way to apply the settings automatically?

EDIT: Found a solution, download latest release, open zip and edit the file located at "/patch/init.qcom.power.rc" (I used Notepad++) and delete the following lines:

# Kcal Configuration

write /sys/devices/platform/kcal_ctrl.0/kcal_min 35

I just flashed BW kernel and spectrum app. Is the spectrum app simple and best for tweaking the kernel? Because the last updated date is showing 17th May 2017. What about Kernel Aduitor, L speed,... etc?
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Dokken2x:
Spectrum its just the app that let the kernel dev create different presets, so it doesn't matter when spectrum was updated.

If you want to tweak go ahead and use kernel audiutor

Thanks ?. I set the preset to 'Battery' and I'm now getting ~2-3 hours of screen on time. Before it was just an hour, thanks for suggesting BW Kernel. But there's one issue that the charging speed is too low now. Not sure if it is related to kernel. Lemme do some trials and errors. ?

Most of the roms don't use QC3.0 as it is known to burn the charging port,not only this even the stock OS don't support QC3.0 and the QC3.0 was just an advertisement thing.

Don't know about how the others check theirs but I use Accubattery for it, it's an amazing free app to know almost everything about your battery.

Guys is this a common issue with ROMS, that every new version seems to bring about or revive old bugs? I had been using custom roms since the days of Eclair, but there are some issues that don't seems to settle once and for all on this device. Especially the Adaptive brightness issue. In one version of ROM it seems fine, in another it seems unreasonably aggressive so much so that its glaringly bright even indoors all the time. Is there any ROM without this issue?

Thanks!

---------- Post added at 06:28 PM ---------- Previous post was at 06:27 PM ----------

LOS is better as in it feels like a stock OEM (Motorola?) firmware without the customizations. Does not have the basic navbar back button disable feature.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] frozenfirevr:
As the name suggests, it is supposed to adapt to your preferences over time. Try teaching it what brightness you want in different lighting conditions.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] glasseffects:
Let's not reiterate Google's statements, we aren't here on XDA for that. In real world, this doesn't work as described. I have tried LOS, and it works great right out of the box. This issue resurfaces in ever other AEX version. So its a bug and should be treated as such.

Teaching AI, is that what mankind is supposed to do leaving all the real world issues at bay? It's auto-brightness, nothing more. There's no point romanticizing about it.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] frozenfirevr:
Who's romanticizing anything?! It works perfectly fine for me. What you want isn't necessarily what everything should be. You don't like how AEX does it? Do stick to LOS. Choice is where XDA comes in. Your words are just noob talk, take away Android, its statements or discussions or whatever and there's no XDA.

Gee... *smh* Your attitude really drives me off. I wish I'd be able to avoid attempting to help such people.

Well, I knew this was coming. If you don't know how to fix a problem, there no point beating the dead horse. Anyway, I made a request to the Devs, and I use AEX since I have developed a preference for it since past few years. It's a good ROM to begin with, but this is a bug and requires attention. My original post was to the Devs, my previous post was certainly not at you, but your reply shys away from being a genuine advice. Didn't it occour to you that was something anyone who knows Android would've tried? Or is everyone a 'noob' to you? Is that how you surf the web or forums with that stratification in mind?

I switched my Z2 from AEX to LOS yesterday to test if heating is related to the ROM or phone itself. Because I can't even touch my phone even it was used for just texting and browsing in AEX. I tried BubbleWrap both and Nameless, the heat issue gone but there was another issue with charging.

Now on LOS I didn't find any heating issue expect when the photos are taken with GCam 6. Also I'm seeing the charging speed above 1500 mA for the first time since AEX 6 versions. But I can't find the easy usability like AEX in LOS. But the above mentioned issue is pushing me away from AEX. At the same time none of other users tell whether there is any issue like I said before. I request Davide to check the ROM again to remove the heating issue from the ROM.

On AEX it took more than 3 hours to charge my phone to 100% in On state (screen was off) and normal time in Off state. Also the phone was heating too much in On state. If I took the phone for checking any notification it heated like a frying pan. This charging issue happened with stock, BubbleWrap and Nameless kernels.

Hi niyonsv,

I'm using AEX ROM since lot of time and I have not faced overheating or charging issues as the ones you have noticed. I would be careful to affirm that they could be ROM related.

So far I found on this forum a plenty of different users experience, regarding the performances of this ROM running on same hardware and this obviously indicates that the variables can be the device and eventually the firmware used with it, I'm propensed to exclude the ROM.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] niyonsv:
Thanks for the reply bro. I too has been using this ROM since AEX 4, if I am correct I remember it had a lot of customizations. I never changed to any other since then coz I really loved this ROM because of it's fast and stable updates, lots of users (one of the few ROMs with a very large discussion), and especially our developer Davide bro. I never even thought of changing to any other ROM. But now I can't use the phone even for a very little casual use. My phone usage was reduced to just calling, WhatsApp, XDA and FB on chrome. But for that too I can't use the phone for more than a few minutes because of the heating issue. For the third photo which I taken with any GCam my phone rebooted because of unable to handle the heat.

My phone's battery is also replaced with a genuine Lenovo one (from Lenovo service center). The charger, the cables, the 300+ apps I installed,.. everything is same while my Z2 was on AEX and now on LOS.

I too want to return to AEX and sure will clean flash the next build and test. I'm still confused if this is because of the ROM because no other user have complained about it.

Thanks again bro..
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] mcalistri:
You're welcome buddy.

The fact that you have replaced the battery leaves me to have some doubts regarding the job made by Lenovo service center, because it is an important detail to take care of in relation to the abnormal heating.

But if, as you say, by using a different ROM such heating phenomenon doesn't appear, it could be caused by a series of factors involving the software environment: ROM + GAPPS + Kernel.

Good luck,

3 hrs to charge and heats like a frying pan, those are the issues I faced before I changed my battery. Check your battery. I'm running AEX 6.6 on latest magisk and latest bubblewrap hmp kernel underclocked to 1.5 . My experience is butter smooth. I can hold my phone and barely feel the heat. My sot is like 5 to 6 hrs on this ROM.

I got only 1 hour of SOT on AEX before changing the battery and barely 2 after changing. But the heat issue was there before and after. I tried BubbleWrap both and Nameless and the heat gone completely. But another issue appeared that the phone doesn't charge properly. It was taking around 3+ hours for getting to 100%. Tried underclocking the CPU too. Tried underclocking the CPU too. In short,

With AEX kernel - heat issue - but no charging issue

With custom kernels - no heating issue - but charging issue

On LOS I am not facing any issue with SOT, charging or heating issues. So I think there's no problem with the new battery.

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] sodacrusher:
You do you buddy.

I see people here and there getting different performance & SoT so, my advice to you is try different things. Don't always stick to something. If it is troubling you, let it go. Never listen to anyone and everyone (there are some times where you should listen) because the way that they use their phones is different from that of yours.

You also have to keep in mind that their phone is some year old or they have changed something in their phone (that is an error that you have to take into account).

I'll tell you my experience. To me 6.6 is perfect but I wanted a kernel (there is nothing wrong with stock or is there? I don't know. You tell me.). Someone, don't want to hurt anyone's feelings, so I am not taking any names, said nameless kernel gave 6 hrs of SoT with 2 days of standby. I got the link from said person, flashed it. It was good until I opened Clash Royal. In the middle of the match it would get stuck (the screen). So I immediately changed to latest Bubblewrap hmp kernel. And now I'm totally cool.

XDA is a community. We try to help one and other out here. I know we have trouble here, like people getting angry and all (some posts back). But in the end we should all try and understand that we all are humans, we all make mistakes ,we all have troubles. We should understand (what maybe going through their minds) others feelings and learn to say sorry. You may say that I'm being spiritual or whatever I don't care much but it's appreciated. I end with this quote "United We stand, divided We fall".
