Ok, that could at least explain the drain.. Coverage here isn't pretty good, and I fetched a few lyrics over 2G.

Charging problems got worse now though, it circles around 25% while being always on the charger, and I'm only doing some light stuff.. I even enabled fast charge.

Some minutes ago, the charging state blinked very fast (showing the bolt or not), it always disconnected and reconnected charger.

I will now flash back B69, let's see what happens.

EDIT: no fix, blink also reappeared. While doing a backup in recovery, it actually charged quickly.. :/

EDIT2: uaaahh, battery drained now to 14%, the UI got very laggy because of the battery empty notification looping, help!

Also CPU temp rised up to d*mn 64°C!!

It just jumped up to 16%, but a few seconds later it's back on 15 again.. While writing this, 14... :(

Do backup and perform clean instal ... it's 30min question and you will know more ....

Every time when I got problem, it was coz the rom ... we are flashing over and over and sometimes phone gets crazy... clean install is the way :)

Will you be using UberTC for your official builds in U2D as well?
[Nexus 4 General] hellsgod:
If the device has benefits from it, yes. Havent much feedback about it on mako.

hells
[Nexus 4 General] flocke000:
I can't really tell since I started compiling my SimpleAOSP builds with UberTC and all kinds of optimizations the same time you started using it.

So I'm not really sure if the performance/battery improvements have anything to do with the kernel or if it's just the ROM.

All I can say is that I don't experience any trouble with the UberTC version, it's stable as always and everything works as before.
[Nexus 4 General] RASTAVIPER:
How can it be a kernel issue when noone else reported such problem?

For me with b70 I didn't notice neither this problem that you mentioned, nor some extra super performance increase that some other member posted here earlier.
[Nexus 4 General] xenyz:
Try a different charger, it sounds 100% a hardware issue. Charge it up in recovery if you want to test.
[Nexus 4 General] Maxr1998:
Thank you all for your answers. I'm actually not sure what's the problem anymore, today it seemed good at first, but 3g drained like hell and in BBS I noticed a 100% *alarm* wakelock. I will do a clean system flash now and see if it helps, if not, a complete clean flash. Will report back.

Seems to work now as I should. I still have a few problems, but I believe they're only (knew that before) coming from Google services (drains like hell until I enable this SystemUpdateService.. well) and nothing rom or kernel related.

EDIT: I already have .93 from apkmirror.com, still have the issues ( [MENTION=5105100]leninke[/MENTION] )

I just read somewhere that, there are problems with play services. The phone doesn't go deep sleep. Search for the newest one, that should be good.
[Nexus 4 General] xenyz:
Unless you're using a custom ROM, in which case you may have to disable SystemUpdateService to stop it always running.

The good news is, most custom ROMs include a service/wakelock blocker, so it can be avoided.
[Nexus 4 General] eurochild:
The only working solution is this..
[Nexus 4 General] Maxr1998:
Nope, I actually have to ENABLE it to avoid wakelock.. Seems pretty funny, doesn't it?

[Nexus 4 General] xenyz:
Sounds strange: why, if SystemUpdateService is causing wakelocks, would it not already be running?
[Nexus 4 General] Maxr1998:
My thoughts are it is running although it's disabled! But since this is nearly impossible, I think it's different: there is the SystemUpdateService which controls the SystemUpdateService wakelock. And as the service is disabled by the rom (CM seems to do such things to save battery) the wakelock doesn't get stopped and runs always (→ battery drain)

Confusion of version

The headline says that b69 is stable and 70 is a test, but in the downloads it says b69 is a test and no reference to test for 70, which is the current most stable...? Having major issues with b68 on my N4, screen freezes and repeats upon restarts, from what I read in the first couple posts, is it unsafe to dirty flash?

Hi [MENTION=647113]hellsgod[/MENTION] . I'm currently using the b70 test , im using default settings except for -50mw undervolted and max screen off frequency 1550 ( the max usable) . I got some music shuttering while the screen is off, its ok when i unlock again the device. Thanks for the attention.
[Nexus 4 General] RASTAVIPER:
B68 and B69 are very stable.

If you have such problems then either you UVed too much or maybe your Rom is problematic.

So, check these matters first.
[Nexus 4 General] 22sl22:
Just thought I'd share what I did for those experiencing wakelock issues, no need to change roms or anything:

Download an Autostart manager (Any one with root access will do): And stop the 3 receivers within Google Play Services that allow updating (There should be 3 but I think there's a few more I stopped). Then when you reboot your phone Play Services won't be able to start the update process thus no more wakelocks

Next download a root enabled App Ops and block Plays services from keeping the device awake.

Now the only major wakelock I have is from Ambient Display which I am fine with. Problem solved :)

Android 5.1 is practically here, this morning google has released source code for 5.1.0r1 for mako, maybe is about hours to come

Before asking for 5.1 support, check this site if there's any 5.1 out for the nexus 4 yet: https://developers.google.com/android/nexus/images As you see, it isn't. All custom roms which update their base to 5.1 still using 5.0.x blobs and my kernel should work with them. As soon as the factory images and the sources are out, I'll update the kernel.

I can confirm that. Currently running hc b70 without any problem on euphoria that was released yesterday. 24 hours later I can say that the combination of 5.1 and HC is perfect! Running as smooth as never before. I can say that I feel my device 1/4 faster and smoother than it was on 5.0.2.

In addition, the Nexus 6 already have a new 5.1 build (LMY47E). It could be that when we receive the update for the Nexus 4, it probably be LMY47E or later.

Hopefully, the build LMY47E or later builds fixes the memory leak present in the current builds of 5.1. In the issue tracker it was said that "This has been fixed internally. We do not currently have a timeline for public release.".

Hey guys. anyone have link Kernel Patch USB OTG for Lollipop ?

Thanks in advance ;)
[Nexus 4 General] IseeDEADbodies:
Hello guys, long time no see.

For the last month or so I'm trying to deal with one problem, but I can't just figure it out. My battery drains like ultra fast. I'm running stock 5.0.1 with hells b68L. The main problem is that when im WiFi I can litteraly see how my battery goes down. For let's say 5 mins of browsing I'm losing like 1 or 2%. In the beggining I thought that my battery just f*ucked up and I've purchased a new one - the result was the same. I've tried so many things like : full adb reinstall, reverting to 5.0, using the stock kernel, trying custom ROMs, using old version of hells kernel, I even reverted to full stock KitKat and nothing helped. Everything happened (or at least I've noticed it) when I upgraded from 5.0 to 5.0.1 somwhere in February. If someone has some thoughts, please share them, because its really frustraning to have so poor battery life (barely making it 2 hours of SOT). I post here, because hells kernel is basicly my "daily driving kernel" and most of these results are while using it.

P.S. I'm not really sure Iif it makes sense, but I wanna ask an additional question. I've bought the phone from Bulgaria, but I've moved to England and that's when I've start noticing the battery issue.. So my point is - could it have something to do with the battery life, since the phone is purchased from another region, or they all are just made for the Europe? Sorry if its an offtopic or something, but I'm really despaired.
[Nexus 4 General] prog19:
Maybe its the systemupdateservice wackelock from playservices ? If it is, download the app disable service and under system tab, ENABLE the systemupdate services on Google framework and playservices. To see if it is this wakelock, install better battery stats and seek the wakelock under partial wakelocks tab

So last night I installed hells core on nexus 4 stock rom. Wow! Battery life much improved.

Questions though.

The double tap feature to wake screen made my screen unresponsive. Had to hold power button for 10 seconds in order to shutdown and restart. Others have same issues? Any fix/workaround?

When i make changes on with hellscore manager do i have to check the "Set on boot"? What if idont? Wont the changes be loaded at next reboot?I dont quite understand this.
[Nexus 4 General] prog19:
Wen k when the screen become unresponsive you have ti touch it with 5 fingers to reset the driver. And if you don't mark set on boot the kernel will boot with stock settings every time

I'm a Brazilian without English Course, sorry and be comprehensive :)
[Nexus 4 General] siretfel:
didnt know about five fingers reset the driver!!!!

and finally, does double tap drain more battery?
[Nexus 4 General] prog19:
The current implementation keeps only a small portion of screen, in the center, energized, thus saving battery, but it will have more drain than if its off.

[Nexus 4 General] poondog:
There's no 5.1 kernel and binaries anyway (since its not released for mako) so the ROM uses from 5.0.2 anyway

The only "kernel" difference is ramdisk but since hells uses anykernel there's no problem

These "5.1" Roms are just 5.1 framework etc from aosp but the main proprietary binaries etc are from 5.0.x

[Nexus 4 General] xanthrax:
First , you don't know exactly how much power a game consume comparing to camera when focus on video , shot on video , flash light , etc ...

Second , the brightness does not affect the stability

Camera is related mostly to CPU and the games use the GPU as well , so the impact on the phone stability is different

The CPU provides support for camera and sound , the games are only applications which are using your phone resources in a different way

sent from my Darkside of Nexus 7 LTE
[Nexus 4 General] WiwiPouPou:
Ok, i think you should read me again, i just say that i think it's not undervolting, because saying it (when the issue exist on stock), is like saying the thing about the brightness :

- there is no proof at all, so advicing users about reducing an stable rock undervolting is just useless, and worse it doesn't make people to search for the real cause of the issue.

- again, it's a stock issue = WITHOUT undervolting !! C'mon ! Hellgod itself said it !

So don't advice users to reduce undervolting when it's not the issue, and don't talk without a real proof other than "one day i had the issue then i've reduce undervolting and since that moment i didn't get the issue again", i got that once in 3 months of undervolting without one reboot. It's like saying "one day i was wearing green socks and my car refuses to start, so i've never wearing it again and now my car always start"... It's just proofless speech, it's dangerous, it's not rational.

I don't get the proof that it's not undervolting, or not increased by it, but the fact that the issue is stock is one argument in that way, the random experience of one user isn't.

Oh, and a 3d intensive game seems to draw more power than camera : just see battery consumption between 5 minutes filming and 5 minutes gaming.
