Well the first thing I would do is check for wakelocks using BetterBatteryStats, maybe set the sync for emails etc. higher.

You could also try using Hells Docotr without tardis, never heard that to be a battery killer though :p

Probably not the CPU Settings but if you want to have some extra juice you should check out [MENTION=4362467]gorilla p[/MENTION]s balance and battery profile - Mako Stuff
[Nexus 4 Android Development] nicknc:
Yeah, I'm not seeing anything in BBS that is abnormal. As far as android settings (sync, etc), I have it set up pretty much the same as I did with my old One S and the Sensation I had before that. Got 3+ hours SOT with both of those.

I'm using gorilla_P's balanced settings, as the battery profile yielded the same results.

Sitting here at 71%, with 6.5 hours on battery and 34 minutes SOT. Nowhere near the numbers I see on here.

I have a faster binned krait, so I've even kept the undervolt turned on.

Maybe it's my battery.
[Nexus 4 Android Development] kevinnol:
Weird, could be the battery but that's some unusual drain there I assume you haven't played games in these 6.5 hours.. ?

And I know it's a expected question but did you try a clean flash of your rom + kernel?
[Nexus 4 Android Development] nicknc:
I streamed a podcast for about an hour on my commute. Have a risk game, but that just uses gcm and a minute or so of SOT every 30-40 minutes.

BBS' report of deep sleep time matches up with how much I've used the phone.

And yeah, I clean wiped away from CM to stock AOSP in the hopes that it was a CM issue.

It apparently wasn't.
[Nexus 4 Android Development] kevinnol:
Since you did a clean flash and use BBS+Greenify.. I'm running out of ideas because that basically solves 95% of the problems out there

Sorry i couldnt contribute further to your battery problem :(
[Nexus 4 Android Development] nicknc:
No problem. Just ordered an Onite replacement battery off of Amazon.

I bet it's the battery.
[Nexus 4 Android Development] lazer155:
Has anyone had trouble with the latest release of Purity rom 8/29 and the TARDIS mod causing a bootloop when the qualcomm dalvik M8 AOSP optimization is selected? It doesn't cause a bootloop as long as you leave it as stock but if that is installed it bootloops. I've used that option before without issue since Purity is an AOSP rom. Could a change in a rom cause that to happen?
[Nexus 4 Android Development] Aaron_Knowles:
Try the CM one and see if that works.
[Nexus 4 Android Development] lazer155:
I tried all the options and each results in a bootloop. I also did a wipe and fresh install of the ROM and it still bootloops anytime you change the libs to one of the custom 3.
[Nexus 4 Android Development] buru898:
Hmm that is definitely weird, that shouldn't happen. You sure you're flashing on a nexus 4 :p.

Just don't flash it then, it doesn't give me any noticeable performance improvements so I stopped flashing it.
[Nexus 4 Android Development] veeholics:
Does anyone experience very long booting time? My boot time is around 6-7 minutes, and that's crazy long. Crdroid + HD R25
[Nexus 4 Android Development] lazer155:
Yeah it's definitely a nexus 4 :) I did just give up on installing TARDIS. I think something was changed in the rom with the update and it's just being weird with all 3 options for some reason. It works fine on other roms and the older versions of Purity. The kernel hells doctor kernel is the only thing I really needed working for improved battery life and it runs perfectly, so it's all fine. :D
[Nexus 4 Android Development] marcus6999:
I'm using Purity too, and got bootloops when flashing TARDIS with the M8 dalvik patches, just leave the stock option when it asks for the dalvik patches.
[Nexus 4 Android Development] johnb380:
Guys read Puritys Header it is built with Linaro now u can't flash other dalvik options anymore.
[Nexus 4 Android Development] apis10:
My experience lately is with phone calls.

Battery life takes a beating during phone calls. I lost 6% after a 10 minute phone call on one occasion and 9% after another 17 minute phone call!
[Nexus 4 Android Development] buru898:
Do you change any kernel settings? You really should.
[Nexus 4 Android Development] apis10:
Yeap. I should!
[Nexus 4 Android Development] nicknc:
Quick update: disabling Google Now is affording me substantially better idle battery life, but still getting poor screen-on time.

Before anyone jumps on the anti-GNow wagon, let me say that I am aware that it consumes battery, and have used it on several other phones since its initial release. It has affected battery life on those, but only to an incremental degree- hence the reason I did not initially disable it.

Beside the fact, I am still struggling to get decent screen on time, which is causing me to suspect a bad battery.
[Nexus 4 Android Development] kevinnol:
Time to try the replacement you ordered :fingers-crossed: with hopefully promising results

--

In my case battery life is pretty decent, but I'm miles away from being an heavy user - Music, Whatsapp. Mails(not push) and some web browsing
[Nexus 4 Android Development] nicknc:
...if FedEx can get their act together and deliver it.
[Nexus 4 Android Development] nixie2121:
What are peoples experiences when using this kernel with and without TARDIS?

Thanks
[Nexus 4 Android Development] Aaron_Knowles:
Tardis isn't some special mod that is only available through HD kernel. Everything included can be found elsewhere, its just a convenient piece of kit.

There are obvious and subtle performance gains flashing an optimised dalvik and the latest GPU drivers. What puts most people off using tardis is they flash the wrong dalvik and end up in a bootloop and instantly blame it on the mod.

I'm not a benchmark fanatic or interested much in peoples benchmarks, but flashing dalvik and GPU updates is the difference between scoring 19k in antutu to scoring 26k.

My "philosophy" on the matter is "why not?" If its an improvement, there's no downside to flashing them.
[Nexus 4 Android Development] nixie2121:
thanks so much.
[Nexus 4 Android Development] buru898:
I keep coming back to this kernel, it's practically perfect.
[Nexus 4 Android Development] nicknc:
New battery is in. Still not getting more than 2-3 hours SOT. 12 hours on battery, 31% remaining with 2 hours SOT this time.

Oh well. It is a versatile kernel, though. Very happy with it.
[Nexus 4 Android Development] Aaron_Knowles:
Barome posted on his g+ HD #3 v1. Anyone tried it? Hoping we'll see a changelog and explanation as to why #2 is discontinued soon!
[Nexus 4 Android Development] kevinnol:
The obvious changes are that there is a new MPDecision (showps), new linux version, a different I/O scheduler and GPU governor - zen and interactive

Everything is smooth and no problems whatsoever can't report about battery life though :silly:

Oh and seems like not all MPD settings are available through synapse for example the boost settings are missing
[Nexus 4 Android Development] lazer155:
Do you know of an app like synapse that shows the other MPD options? Hopefully synapse is updated soon to support them.
[Nexus 4 Android Development] apb_axel:
Oh yes, next UKM version should include all missing MSM MPDecision tunables ;).
[Nexus 4 Android Development] lazer155:
Have you had any problems with synapse crashing after flashing the latest #31 HD? It was working okay until I tried to restore one of my profiles. After that each time, I open synapse it force closes. Maybe I need to get rid of my old profiles and remake them.

Edit:

When I deleted all my profiles along with the synapse folder on the sd, synapse still shows them as options to select inside the app. I tried deleting and reinstalling the entire app and those profiles still won't go away.
[Nexus 4 Android Development] apb_axel:
Try hitting the Clear Synapse Data button in tools section, should fix it after that.
[Nexus 4 Android Development] lazer155:
That removed it from the list but as soon as I restore the version 25 battery script, it still causes immediate force closes when I open synapse.
[Nexus 4 Android Development] apb_axel:
Most likely that profile doesn't work for version #31 anymore, you need to configure manually or find an updated profile.
[Nexus 4 Android Development] lazer155:
That fixed it. It's working fine with freshly made profiles. Thanks for the help :D
[Nexus 4 Android Development] lordvj:
Hey barome. We're itching to see the changelog for gen 3 r1 ?.. Btw I tried installing it but boot got stuck at the kernel logo.
[Nexus 4 Android Development] ralphreyes:
I had the same problem. I'm wondering if the new kernel has the kexec patch for multiboot and if it supports f2fs yet.
[Nexus 4 Android Development] masternothing:
I have same problem stuck on android... Logo. Allf2fs
[Nexus 4 Android Development] HarisA1:
I got r1 to work. Flash Uninstaller HD then flash the new r1, wipe cache and dalvik. Hope that helps.

-N4
[Nexus 4 Android Development] scoonie:
Is there a cm version to v3?
[Nexus 4 Android Development] johnb380:
You guys either have to flash the kernel with a clean flash of your ROM or flash the uninstaller then the new kernel.
[Nexus 4 Android Development] nibblet787:
I'm running MultiROM and all f2fs and nothing gets me past the "Android hells powered" boot logo. Running the uninstaller does nothing. Deleting the Frandom directory does nothing. Wiping dalvik and cache does nothing. I've posted on his G+ page, but have yet to see a reply.
[Nexus 4 Android Development] Aaron_Knowles:
Test builds are never CM. Barome only tests AOSP then when it goes live he releases CM version.
[Nexus 4 Android Development] cesarguaro:
Rom Liquid

Hi sorry for the question... but what library should i choose in tardis on liquid rom? :confused:
[Nexus 4 Android Development] Medel-Silver:
I think v3 don' have f2fs support, don't work for me with full f2fs
[Nexus 4 Android Development] robbieast:
Can we please get the change log for v3 #1.

Also what's the kernel undervolt on v3? Is it still -100v
[Nexus 4 Android Development] nibblet787:
Barome just posted last night on his G+ page that the current version of R#3 v1 is NOT f2fs compatible.
[Nexus 4 Android Development] lazer155:
Does that mean if we currently use a rom like Purity which is f2fs compatible, we shouldn't use this version? I didn't know Purity was f2fs compatible until I just checked.
[Nexus 4 Android Development] johnb380:
Naw that just means if ur system is formatted to f2fs that u can't use the new kernel with it Purity is just compatible with f2fs its not only for it it works fine on ext4 also friend.
[Nexus 4 Android Development] barome:
New generation (the third, yeah I know) now available !

Big, BIG, B I G changelog, so read Hells latest one and mine ;)

You can use TARDIS too of course !

Enjoy !!!
[Nexus 4 Android Development] harsh.ea:
Too many crashes on startup here. Even the system crashed. Back to #2
[Nexus 4 Android Development] barome:
Many users test it without crash. Try this :

- Flash your ROM

- Restart

- Flash HD
[Nexus 4 Android Development] nibblet787:
I'm still getting stuck on the "Android hells powered" logo. Is f2fs still not included?
[Nexus 4 Android Development] harsh.ea:
On stock Rom so flashing Rom is not an option
[Nexus 4 Android Development] barome:
Do you read changelog ? no ;)

Thanks for your amability... Do you try HD uninstaller ?
[Nexus 4 Android Development] nibblet787:
Sorry, I did read the changelog, but I must have missed the part where it said f2fs was no longer supported. Thank you for your hard work! Sadly, it looks like I'll be stuck on the old kernel until I get time to reformat all my partitions. :(
[Nexus 4 Android Development] barome:
I'll add F2FS in the future, stay tuned. Just needed many many commits, and tired...
[Nexus 4 Android Development] nibblet787:
OK! However, can I ask your own opinion on whether you think f2fs is worth using at all? I always thought it was, but I've seen other kernel developers dropping support for it recently, too. It's been making me question whether any speed gains I've seen are real or not.
[Nexus 4 Android Development] nixie2121:
Thanks so much for the update. I am using without TARDIS. Is the default settings good for battery/performance mix? or does it tend to lean one way or another?

Thanks again. (which app do you use to change settings?)
[Nexus 4 Android Development] harsh.ea:
I'll do that and let u knw.

I just flashed HD uninstaller, and nothing happened. Or that's what appeared to my eyes.

Can u tell me the function of HD uninstaller?
[Nexus 4 Android Development] barome:
My opinion ? placebo effect and many bugs when you change ROM or kernel (I lose all my datas)

Stockdemand / ROW is a good idea I think. I use Synapse of course, what else ? (Yes, Barome is inside !!!)
[Nexus 4 Android Development] txuki2005:
nice to see you go back.

Welcome!!

Thanks for another update.

In this moment, i will stay on R25 because is the best combination (smarmax) wiht mahdi rom. I will wait to see your efficiente changes on future releases.

Miles thanks reall7
[Nexus 4 Android Development] kevinnol:
R1 is a pretty nice kernel but the new MPDecisions event boost doesn't like CPU1, the weird thing is it's only CPU1 neither of the other cores have problems. Using Mahdi

Can somebody relate to the problem? or is the problem on my end? (flashed R1 "on top" of the stock boot.img)
[Nexus 4 Android Development] johnb380:
You flash the HD uninstaller then you flash the new kernel friend and no more bootloops... The uninstaller I believe is meant to remove the ramdisk changes for the old HD kernel so that when flashing something else (another kernel) it doesn't bootloop after
[Nexus 4 Android Development] SeanInToronto:
If we flash the uninstaller, do we need to flash TARDIS again? Or only the kernel?

I have a few other questions:

Which governor is best for battery, other than conservative?

And can someone explain to me the difference between ondemand and stockdemand?
[Nexus 4 Android Development] kevinnol:
If you just care about the dalvik patch and the GPU drivers then no, you don't have to but if you want the init.d tweaks yea you should flash TARDIS again as the uninstaller deletes them.

Best governor for battery hmm.. if you have event boost activated the governor doesnt matters that much. I would say with the right settings intelliactive(?)

stockdemand is googles default governor while ondemand is stratosks custom one
[Nexus 4 Android Development] SeanInToronto:
Thanks for the info, I appreciate it!

What settings would you change with intelliactive? I got such good performance with that governor, I always thought it would be poor with battery.

And between ondemand and stockdemand, which is better with battery life?
[Nexus 4 Android Development] robbieast:
Is undervolt still -100 by default?
[Nexus 4 Android Development] SeanInToronto:
I'd also like to know about the undervolt, I don't think it's -100 mV anymore.
[Nexus 4 Android Development] kevinnol:
̶d̶̶e̶̶f̶̶a̶̶u̶̶l̶̶t̶̶ ̶̶i̶̶s̶̶ ̶-̶2̶̶5̶̶.̶

-----

The good performance is because you jump directly from the event boost freq to the highspeed freq wich default is 1512 mhz :p

between ondemand and stockdemand... don't know I think it's more of personal factor if you like stratosks or googles ondemand but I may be wrong someone with more knoledge should be able to answer

If you just care about battery life use conservative, you could also change some hotplug settings for example... lower the event boost freq or change the hotplug threshold
[Nexus 4 Android Development] robbieast:
How do you know its -25?
[Nexus 4 Android Development] kevinnol:
Im sorry I checked on a CPU table I believed is correct... :crying:

So to make sure I flashed the stock kernel to check the voltages and apparently R1 uses stock voltages
[Nexus 4 Android Development] robbieast:
Any synapse profiles on the way for R3 #1 [MENTION=4362467]gorilla p[/MENTION]
[Nexus 4 Android Development] Aaron_Knowles:
Haven't seen him around in a while. Beginning to think he switched phones!
[Nexus 4 Android Development] gorilla p:
Dude, don't get me started. The place that fixed the screen on my phone did a crap job and I brought it back to have them fix it. I'll have it back this weekend.

On another note, I'm using my OLD Samsung Gravity Smart

which I had to get really creative with to get it working reasonably smooth and have more than like 4 apps on it.

There was one single custom ROM made for it and root. I got that on there with Link2SD and Smart Launcher and it's running pretty well.

So anyways, I had totally forgot that this thing had T-Mobile Wi-Fi calling. T-Mobile is rolling out their Wi-Fi calling hard now and are distributing routers like they did the first time for people to use. The ones they have to customers before (Linksys WRT54G-TM) were probably the best Wireless-G router ever made and the ones they're giving out now are really good Asus routers.

They're also looking at making current phones compatible via software/firmware updates. I would LOVE to see the Wi-Fi calling app pushed out via the app store, but I may be getting too hopeful.

Let me know if anyone thinks they could use anything from this phone to adapt the Wi-Fi calling feature to another phone.
[Nexus 4 Android Development] buru898:
I've used F2FS since it was available for our devices. There are NO bugs, I have never lost any data changing roms or kernels. I have no idea how you can be messing that up, but that's entirely user error.
[Nexus 4 Android Development] lembang:
[MENTION=2923435]barome[/MENTION]

placebo effect..hmm i will say i dont really agree with this. I feel a significant improvement with f2fs. I hope you will add that feature back to the R3..but its all your call [MENTION=2923435]barome[/MENTION] your are the boss ^_^V im still stick with R25..I do love your kernel since the dark chocolate era :good:
[Nexus 4 Android Development] Sblast:
[MENTION=2923435]barome[/MENTION]

Hi barome,awesome kernel.

Any chance to add support to Wake Gestures?

Cheers
[Nexus 4 Android Development] Medel-Silver:
And F2FS is under constant development, it means constants improvements, I use F2FS since the begining, and don't go back to ext4

Why did u switch the toolchain from Linaro to GCC ??? isn't Linaro more optimized as compared to GCC ??
[Nexus 4 Android Development] jimyiak:
if it's the same as roms..gcc is more stable than linaro..linaro breaks some apps and the gain of speed isn't worth it..dario also change his toolchain to purity rom from linaro to gcc and the rom is running great..can i ask something..if i'm in sabermod franco kernel do i need to dirty flash rom to come to this kernel?? thanks...
[Nexus 4 Android Development] fr3quency:
I don't think so. I've never ran into such things, unless I had to install another kernel(coming from Hell's Doctor, that is) which I would had to flash the Uninstaller.zip for this specific kernel.

Plus, if I recall correctly, I had flashed Sabermod Franco, switched to ak, and then Hell's Doctor without any problems. :eek:

[Nexus 4 Android Development] gorilla p:
I don't like the way that looks at all. What ROM are you using?

I'd recommend a clean wipe and flash a stable ROM like Dirty Unicorns (tons of features) , HD, AK or unleashed kernel, disable notifications on almost everything in app settings, Greenify almost everything.

Is that for me? Btw I'm using stock ROM KitKat 4.4.4

[Nexus 4 Android Development] Bladyle:
Hi,

I'm stock user (ROM and Kernel) but I want totry this kernel but first some questions :)

Should I flash T.A.R.D.I.S. MOD or only the kernel?

And second question do I need some app and tweaks if I flash only the kernel for best performance/battery?

Thanks!
[Nexus 4 Android Development] neol23:
Is there any reason why the voltages are set so high? I've UV -150mAh - no issues, everything works perfect for now :) ...
[Nexus 4 Android Development] Ravzz_Sv:
TARDIS mod is nothing but a collection of some general tweaks including latest gpu drivers , modified dalvik patches ( flash only if u use dalvik and not art ) , fonts , bootanimation .. alongside all these it also applies some init.d script tweaks and modified hosts to block ads ... so if u dont care care abt init.d tweaks and ads then dont flash tardis as u can get other stuff from MAKO repository ...otherwise its a good mod ... worth flashing...

for the app thing u asked ,, i ll recommend to use syanpse + ukm to tweak ur kernel properly according to ur need and use Greenify to hibernate most battery consuming apps .. :)

Did you use chrome on android to download it? It has given me problem in the past, some files gets downloaded badly.
[Nexus 4 Android Development] Bladyle:
No. The only way I was able to install it was when I install the MOD first and then the kernel.. No idea why
[Nexus 4 Android Development] Aaron_Knowles:
Happens often to me on a clean ROM install. Usually I have to let the ROM run first then reboot back in to recovery. I don't understand why, though.

I love this kernel.

I have benn using R25 for long and happy with it.

I needed to try the new version R2,

Can i know why do Min CPU speed settings revert after i set them ?

And can you tell me how to set the hotplug like it was on R25

Thanks
[Nexus 4 Android Development] Aaron_Knowles:
All fine on my end. Every time you open Synapse just press the X to keep the values you've previously set.
[Nexus 4 Android Development] brian88:
I flashed this mod, so now I have to reflash rom if I wanna change to another kernel? I've flashed hellscore b43, but still see the bootanimation of this mod, that means, this mod's still here?
