Why the default C-States are only ON for C0 and C3 and in this post you (hellsgod) recommend enabling all but C1? http://xdaforums.com/showpost.php?p=57601295&postcount=9650

What C-States should be ON?
[Nexus 4 General] hellsgod:
Because that's stock behaviour (all on except C1). If you're enabling C1 you could encounter flickering or other instabilities with most kernels.

[Nexus 4 General] dcop7:
So C0 and C3 should always be on. The C2 could be on or off? What do you recommend?

Hi, on CM12 do you have better battery life with hellCore or with Stock (CM) kernel? I can't identify it. THX

[Nexus 4 General] Aashuk Mehta:
I think it isn't wise to ask in a kernel thread that is your kernel better than blah kernel?

It's for you to decide which works for you.

That being said, any cm user here should kindly answer this question

Just want to say that music playing improved, still not bullet proof like other kernels but it's enough to renew my hopes on the kernel :)

It's for me conceivable, that someone writes, with CM kernel I have better battery life, but hellCore give me more and more features (like DT2W etc...)

Google Play Crashed

Hey guys! I've recently flashed Hellscore 68 and 69 in a mako with 5.0.1 with baseband lrx22c and Google Play crash right after open, and if a try several times it pop up every a few seconds the classic crash message.

I flashed b68 yesterday after updating to Lolipop. I found out that swipe2sleep and swipe2wake had been removed. Is there anyway to add these functions back? Doubletap seems not stable for me.
[Nexus 4 General] hellsgod:
No. You have to remove DT2W and add S2W/S2S by yourself in the sources and recompile the kernel.

Talking about maximum performance.

Which I/O scheduler is the best?
[Nexus 4 General] dcop7:
There isn't one. Try and see what I/O scheduler fits you best.

My favorites: ROW and FIOPS.
[Nexus 4 General] hellsgod:
Questions like "what is best for" are really hard to answer. FIOPS and ROW are both made with flash memory in mind. I prefered ZEN for a long time, but decided to change to FIOPS some time ago. Maybe ZEN is a little more battery friendly, because its much simpler than the others (like SIO and NOOP)

Try to upper the readahead to 2048 with FIOPS, thats a setup I've heard should be a very good one :)

[Nexus 4 General] khanhtrinh:
Could you pleased be more polite and open-minded? I had been using your kernel, version b45, for a long time, so I didn't know you removed that function on purpose or because it is difficult/impossible in Lollipop. I just asked, not demanded, and i would be more grateful if you could have answered that politely, not challenged me on recompiling the kernel on my own if I ever wanted to have some features.

Thanks for your awesome kernel. But I don't like your way of response. Oh yeah, that's my business. I know.

Actually you can answer this one. For maximum performance, use scheduler NOOP.

Keep in mind sometimes maximum performance isn't what you really want, though. For example, what do you want to happen with 2 apps getting maximum performance io, at the same time? This is the main reason io schedulers are used at all.

this keeps soft bricking my phone my setup was liquid smooth 3.2 milestone + this kernel and every time i load it up it ends up bricking
[Nexus 4 General] acejavelin:
Isn't LS 3.2 a CM KiKat based ROM? You have to use the older version for CM. Check OP.
[Nexus 4 General] Dasitmane:
i was using b64, it still bricked
[Nexus 4 General] acejavelin:
b64-CM? Odd... I used that combo a while back and it was fine. Are you coming from a different kernel or LS stock kernel?
[Nexus 4 General] Dasitmane:
stock
[Nexus 4 General] acejavelin:
Boot once on stock kernel and make sure everything comes up first, then flash kernel.

And I am questioning myself now, LS may need the AOSP kernel, the 3.2 thread makes no mention of CM base.

Anyone experiencing huge drain on 3g, btw on b68 with simple aosp rom
[Nexus 4 General] xXFiveSeveN57Xx:
That was pretty much the same question I wanted to ask! If I'm on WiFi all day, everything in the battery stats is fine and I get a SOT of more than 4 hours.

But if I'm on 3G in the morning, the drain is extremely high. Also in the battery stats most of the apps like "Play Services" "WhatsApp" "Chrome" etc are on the top of the list when I'm on 3G. The battery stats of all those apps show me that "mobile radio" is active for more than 1-2 hours even if I used the apps only a few minutes.

So, I thought that this was a baseband issue due to Lollipop not "liking" my "old" .98 KK-Baseband. I flashed the 5.0.1 factory image including the new bootloader and the new 1.05 baseband. Still facing the problem. Tried a few different custom roms. Still no luck.

My settings are totally equal to those I've been using for KK for a long time (only sync contacts & location on powersaving-mode). Is this a fixable issue? If so, can anybody link me to that fix? I've been searching the last few weeks and haven't found anything.

Has this anything to do with the kernel or the ROMs I am using? Or is this a common Lollipop issue?

I'm currently on latest Purity and the latest hC-b69-t3.

Danke dir hellsgod, and all you others contributing to this awesome kernel!
[Nexus 4 General] acejavelin:
No... Same setup, SimpleAOSP and b68, no huge drain issues at all. Well, no more than stock anyway, mobile data will take a lot more battery than WiFi and if your signal is less than excellent the "drain" can get quite large.

Normal battery troubleshooting applies here, find out what's keeping it from deep sleeping or waking it all the time and stop it.

BTW, kernel would have very little effect on high battery use on mobile data, or anything else for that matter...

---------- Post added at 08:08 AM ---------- Previous post was at 07:50 AM ----------

Your "issues" are the same as previous poster... Mobile data will suck battery more than WiFi, and WhatsApp and Play Services are big parts in this, thanks in many ways to location services (probably) since when your on mobile data your often moving and these, and many apps that use Play Services (most do actually) are following your movement, thus keeping the device awake and location services uses data.

Install something like GSAM and Wakelock Detector and see what's really using the battery.
[Nexus 4 General] xXFiveSeveN57Xx:
Hello and thanks for your reply.

I have WakelockDetector installed since my first days with the N4. And the problems aren't wakelocks. This is what confuses me! My device is - according to WLD - 95% in deep sleep. This is the same value I got with Purity 4.4.2 the last 10 months. It seems like a Lollipop issue for me because I've been using location services for a long time now and it never sucked so much juice out of my battery as it now does on Lollipop. When you google "mobile radio active Lollipop" you'll see that many users complain about this problem. And all of them have it since Lollipop.

Greetings
[Nexus 4 General] acejavelin:
I don't see it I guess... But then again I don't use WhatsApp (gasp!) or really any other realtime messaging apps except Hangouts on my N4. My deep sleep times are about 80%-85%, how you get 95% is amazing. I get about 4 hours SOT on WiFi and 2-3.5 hours on mobile data but it varies a lot based on signal strength. Its normal and not kernel related.

In WLD, go to settings and turn on Advanced Mode, it is disabled by default to not show system apps, it might show a different story, and GSAM always shows very different results than Battery in settings.

I'm not saying your wrong, but in order to stop battery drain, you have to find the real culprit.

I had problem only with dt2w feature. All other features worked. After couple of hours found it is problem in rom, i think, because when I disable ambient display, dt2w works without any problems... I'm on simple AOSP, build 11.
[Nexus 4 General] acejavelin:
Yeah... BaNkS says the issue with DT2W not working is purely kernel related, not SimpleAOSP ROM related at all. Funny thing is it worked fine up until build 11 and then only fails when Ambient Display active, yet worked fine on build 10. I respect the devs over there but each build is such a mixed bag, thing get better and worse at the same time, I really liked SimpleAOSP, but I dunno, might be time to start looking elsewhere.
[Nexus 4 General] flocke000:
Working fine for me on the newest SimpleAOSP. They cleaned up the code a little and removed their broken init.d implementation completely.

hells-Core installs its own init.d support if none is present when you flash it and it seems to work fine so far.

Try to flash your ROM. If that doesn't work, try to flash the attachment. It sets the selinux mode to enforce

sdcard0 not found after flashing kernel

I just installed b69 using HellsCore U2D. Everything is working fine except /storage/sdcard0 is "not found". The folder is visible in ES File Explorer and Root Explorer but it is not accessible. I'm running stock lollipop 5.0.1. I was using Franco Kernel #215 without issue before flashing Hells-Core. I did a quick search, but came up empty. Any ideas? I assume I missed something obvious.

EDIT: I found everything mounted as /data/media/0. Is this normal for the sdcard mount point to change?

EDIT: I'm getting a "no sdcard" toast error when trying to download from AFH in Chrome. Looks like there is no way to change the default download location in chrome.

EDIT: Finally figured it out. Had to flash stock 5.0.1 boot.img before flashing Hells-Core since Franco modifies the ramdisk.

Do you think it's a problem with kernel or something else?

I was using latest Rastapop as secondary rom with HC b69t3 and everything was working fine till the moment that I changed by accident the selinux mode.

From that moment, Rastapop gets into bootloop.

I already reflashed Rastapop and HC and nothing changed.

Also, I tried selinux.zip which changes selinux to permissive and flash it through Multirom TWRP, but also nothing changed.

Any ideas?
[Nexus 4 General] deani77:
Yes, using that combination right now...
[Nexus 4 General] hellsgod:
I'm not that much into the whole selinux thing, thats why I don't change anything in that matter. The kernel uses the default mode your ramdisk is shipped with. Maybe it has something todo with MultiROM? I haven't changed the selinux mode by myself, and because I don't use MultiROM atm I don't know how the system reacts if you change it on your second ROM.

[Nexus 4 General] sykopompos:
I've noticed some screwy behavior with multirom and selinux myself when k was trying to figure out why frank wouldn't load as a secondary and basically everything in the sepolicy was getting denied causing all kind of failures.

I'm not sure if multirom somehow redirects the policy or maybe throws it into a piggy back permissive mode somehow and that would have been the cause of it but this is the only case I have heard by changing it to permissive

If you have touch to wake disabled, and dt2w enabled, it's almost impossible to accidently turn the screen on, because you have to tap fast, 2 times on 2x2 cm square in the middle of the screen...
