I just installed the factory image of KitKat, then the most recent OTA update. This is my first time on KitKat, I'm seeing dreadful battery life when the phone is in idle. I have the same apps installed as I did when using 4.2 and 4.3 roms, the same setup.

I see from reading reports, quite a few KitKat users have reported poor battery life. Was this an issue with the new OTA update that came out a few days ago?
[Nexus 4 General] Rusty!:
No, as in tap 'mode' on the screen:

Still getting SOD on 4.4.2 (only started on Kit Kat).

On the plus side I've noticed it only happens when I'm on the work wi-fi (802.1x EAP. TLS), so looks like an issue there...

Mine is soo nubby right now after that update. It comes and goes though and definitely happened on jelly bean for me as well. Google is a hot mess sometimes
[Nexus 4 General] BoneXDA:
Standby drainage improved to ~0,5%hr from 4.3 to 4.4.2 (WiFi on, data, sync & Now! off), and opening, switching between and scrolling in apps are noticeably snappier on ART. On the other hand the phone gets hotter browsing, Flipboard, camera, Timely etc. with faster drainage, as if the phone just drew more power for these operations... besides MX, the only app giving me problems is an unofficial 3-letter navigation. Real Racing remains choppy though.

(BTW, what is the difference between brown and green mobile network line?)

Just ran Speedtest on the home 10MBit network:

Desktop: 43ms ping, 10,59Mbits download, 0.53Mbits upload (as in contract)

Mobile: 27ms ping, 10.54Mbits download, 0.53Mbits upload
[Nexus 4 General] Jazavchar:
Can I get some opinions on this?

Whenever I try and flash a custom kernel (doesn't matter if it disables mpcdecision or not), when I return to the stock Kernel, mpdecision remains unavailable! Even though it is turned on in trickster mod, even though I've specifically enabled it? The only way to get it back to normal is to flash system.img and boot.img.

Something like this never happened on 4.3, and I've flashed dozens of kernels and each time, returning to stock was as easy as flashing it from recovery. Now, I have to flash system.img and boot.img via fastboot to return everything to stock. Anyone with some ideas?
[Nexus 4 General] RealSlimShadyMC:
My WiFi is fine. I get around 12mb down 1.2 up, however in comparison, on my PC, using Ookla speed test I get around twice that

[Nexus 4 General] maritimesbob:
I take it the new dialer with KitKat on the Nexus 4 is buggy just like the widespread reports across the net?

I have a rooted stock rom (factory image 4.4.2). Received a call today and the dialer froze up and I could not terminate the call! I also tried calling my voice mail, that resulted in me not being able to select any options and the dialer/key pad would not appear, the screen remained black!

Very frustrating, KitKat is a promising looking release and the dialer is visually so much more appealing than the aosp offerings of before. I've ditched it and gone back to factory 4.3 until KK becomes more stable. I need a working phone where I can make and receive calls, running stock KK is too risky at the moment and that's without trying to customize and enjoy the rom. Not to mention the battery drain, unless you disable a bunch of google apps or whatever to stop the drain. Surely from installing a stock factory, it should not kill the battery so much. Most people who have no idea of XDA or rooting phones will be disappointed by all this after what they think is an important system update.

Google appears to have pushed out this rom/release in a hurry for Christmas?
[Nexus 4 General] jadephyre:
Don't know, I made a lot of calls since KitKat dropped, and I never had one failure or hangup with the dialer.

[Nexus 4 General] acejavelin:
Same here... Make/receive lots of calls, never had a single issue.
[Nexus 4 General] luisjoseb:
I use my phone for calls with 4.4, 4.4.1 and 4.4.2 no issues and working fine making and receiving calls
[Nexus 4 General] Fatherboard:
The dialer is less intuitive than the one in 4.3 imo, but I haven't encountered any noticeable bugs. Sometimes, at the end of a call, the dialer takes a few seconds to go back to the previous screen (unless I force it). I encountered the same behavior with 4.4.
[Nexus 4 General] Rusty!:
Look at the updater-script of the kernel(s) you're flashing. Sounds like the script is removing /system/bin/mpdecision
[Nexus 4 General] maritimesbob:
Thanks all, I'll have another go at flashing stock factory KK rom and see if the dialer plays nicely for me this time.

Howe are the custom roms coming along? Looking to try a stable rom with a few features (status bar and nav bar) otherwise, I'll stay stock with xposed/gravity.
[Nexus 4 General] dethrat:

I've been experiencing a massive battery drain, and I've searched and seen nobody else with this apart from people on the Nexus S on 4.0.4. What is this system_server, and why is it taking so much battery?
[Nexus 4 General] Rohit02:
NO... On 4.4.2 you get more free RAM but looking at the screenshot it looks fine because you have plenty of apps working in background..

So that depends on number of apps to..
[Nexus 4 General] RealSlimShadyMC:
Edit: nvm I did some reading. System_server is the core android process. I can only assume it is the same as "Android System" under battery settings. if you're on a ROM, try changing it.
[Nexus 4 General] XxVcVxX:
I'm on stock with Franco installed, and it only appeared on 4.4.2, not 4.3, so it shouldn't be apps
[Nexus 4 General] RealSlimShadyMC:
Can you tell me if the issue persists with stock kernel/another alternative?
[Nexus 4 General] manpildo:
You mean the fact that apps take 0B of memory? It's because they aren't running any processes, only services.
[Nexus 4 General] vukaleksic:
yep, I didn't saw that on any other previous versions of android so I'm just asking if it is some error or normal behavior :)

What's the deal with "Android system" using so much battery in 4.4.2? Battery life completely tanked on me since the update, even on a clean install.

Uh yea I guess... I just reinstall them from the play store, I don't use titanium or any of those backup apps
[Nexus 4 General] jadephyre:
Hm, then i'm kind of out of ideas... I never saw any excessive battery drain on my phone, wether on stock nor on CyanogenMod.
[Nexus 4 General] lowrider262:
Yea same here, I'm gonna try to fastboot the stock image since last time I upgraded from 4.4.1 to 4.4.2 and see if that helps
[Nexus 4 General] acejavelin:
How long have you had 4.4.2 running? Mine did this for about 2 days then it seemed to just settle out and go back to normal... Not really sure why but have heard similar stories with other Nexus 4's on 4.4.2. I side loaded it BTW.
[Nexus 4 General] manpildo:
I've been on stock ever since KK came out and for example today I got 6hrs SOT and 10% remaining with Google Now, all location services and Touch Control enabled. I'd call it decent. Either stock kernel has been immensely improved or the bashing of mpdecision has been blown out of proportion. I'm tempted to try custom stuff to see how it fares in comparison, but I'm trying to rehab myself from flashaholism. Tbf I think it has smth to do with the fact that I've never been on the same setup for this long before, the battery has had a chance to settle in properly.
[Nexus 4 General] Zehlek:
Do you have any apps that run in the background?
[Nexus 4 General] manpildo:
Yeah of course.
[Nexus 4 General] XxVcVxX:
This screenshot is taken on AK kernel, still stock ROM, with Xposed installed.

As you can see, its still draining a lot, albeit less, which is I believe due to me disabling quite a lot of Google apps like Keep, G+, and Drive. I'm still getting less than 2 hours on screen time.
[Nexus 4 General] RealSlimShadyMC:
Processes don't "settle". Its 0 or 1 in terms of processing. Its not an animal, it doesn't need to "adjust". It must have been a coincidence that it disappeared after a while.
[Nexus 4 General] zaraza23:
Any solution? Someone have something like that? Why dialer drain my battery?

I understand and agree with what your saying, but at the same time it's what happened to me and a friend with a N4... Crazy battery usage for about 2 days then it just stopped for no apparent reason. My terminology or description may be flawed, but it doesn't change the fact that is what happened.

[Nexus 4 General] XxVcVxX:
On stock kernel I don't seem to have hotplugging? O.o I don't have anything else set but the cores don't seem to go offline, they stick at 384 MHz, or is it just stock kernel boosting them for smoothness?
[Nexus 4 General] Kendaihou:
I'm having some problems with my phone now, they randomly popped up. Email services doesn't pop up my email when I get one so it goes into a sync loop. I know this is not new but I'm having it on 4.4.2 KitKat. Also on my battery stats "Android system " is killing the battery. It just randomly popped up and won't go away. Rebooting phone doesn't do anything.

Any ideas?
[Nexus 4 General] eckbauer:
This is my setup:Stock OTA 4.4.2

It looks like G+ and Gmail sync's are causing a massive battery drain (stuck in sync loop),which in turn causes SOD with led notification flashing.
[Nexus 4 General] XxVcVxX:
On stock I couldn't get MPDecision to work so I went to Faux and this is what happens.
[Nexus 4 General] sid.8491:
every time i increse volume of media while earphones plugged in, it shows me a warning. how to permanently turn that warning off??
[Nexus 4 General] aeoveu:
GravityBox and a few other mods let you.

---------- Post added at 05:14 PM ---------- Previous post was at 05:11 PM ----------

Funny how I was thinking that G+ or Gmail or some sync could be the cause of the SOD - since the app didn't help in android 4.3 (And I assume it won't help in 4.4 either)... Not sure how I landed at this conclusion, but if you wrote it as well, then...

And I never had this SOD problem on the GNexus. Also, since it only happened at night, when the charger was plugged in (I rarely got a SOD when the phone was active...but it has happened), and others mentioning it's some wifi-related bug, then thus might be it.

Also, I usually have some notification waiting whenever this happens - either Gmail or Whatsapp or some SMS.
[Nexus 4 General] eckbauer:
I have turned off all sync's,will see how it goes.

WiFi+on charge+receiving notification=SOD (but not always).

This started since 4.3 for me.
[Nexus 4 General] aeoveu:
Could it be the automatic uploading of pictures to G+?

Man, I wish it would get fixed. Where I live, device exchanges don't take place - they yank it open and repair what's required... and that's open for interpretation!

(And each time I look at the N5's low light camera images, I envy the phone since I haven't heard of the N5 crashing in the middle of the night...)

Le sigh.
[Nexus 4 General] eckbauer:
The automatic uploading of pictures to G+ i had unticked under sync,but when i looked again it was ticked.:confused:

You could be right with uploading pic's to G+ sometimes it goes into a sync loop.

So now i disabled G+ completely and enabled Gmail sync again.:fingers-crossed:

Its more a software or app problem.

Regarding the N5,ill maybe wait a couple of months before i order mine.
[Nexus 4 General] manpildo:
Something is seriously wrong here, it shouldn't be like this. I take it you've tried all the necessary wipes and stuff? If so, then I have no idea.
[Nexus 4 General] XxVcVxX:
Yeah, full wiping, even wiping the storage. And right now, I'm at 1hr 15mins of on screen, and I'm at 38% battery. I'm currently on Omni and had tried a few other roms, and still had this massive battery drain issue, and for some reason now, my phone instantly dies at 30% without any warning, and needs to be charged before booting up again.

[Nexus 4 General] jekkel:
Stupid question maybe, but what happen if I factory reset the stock 4.4.2? Will it go back to jelly bean? And if so, will I receive kk ota again?

I'm asking because of the higher battery drain. Battery doctor says that the user login of Google drains the most of the battery. I thought that maybe a clean start would help.
[Nexus 4 General] RealSlimShadyMC:
Factory reset wipes /data /cache and /dalvikcache, not /system, or else you won't be able to boot.
[Nexus 4 General] jekkel:
What? I'm on stock. Don't think that it won't boot. Otherwise what is that option for?
[Nexus 4 General] snahrck:
/system is what is modified in a system update, such as when you receive an OTA. He said that IF a factory reset wipe out /system your device would not boot. But that is not the case, since factory reset wipes only /data /cache and /dalvikcache. Therefore it is ok to do a factory reset. You'll go the the default settings of KitKat.
[Nexus 4 General] jekkel:
OK, thanks. But do you think it would help to reduce the consumption of android.uid.systemui?
[Nexus 4 General] giuvilas:
I got it. And personally speaking it would be amazing seeing Google releasing 4.4 for gnexus (and why not nexus s.. In this case it would be amazing.. It means that 4.4 it's seriously awesome).

And from Google I was expecting a move like this instead of the official "the 18 months support ended"
[Nexus 4 General] vickpick:
Yes, but the problem will be battery drain.
[Nexus 4 General] RealSlimShadyMC:
really?

So having the Mic in an always on state listening out for a specific hotword won't drain battery? of course it will. as sad as it may seem, the S4 Pro and A15 in the Nexus 4, 7 2013 and 10 just can't do it without significant battery loss.

Hi Guys,

is there a fix yet for unstable bluetooth on 4.4.2? I had constant dropouts on calls in my car using the hands free so had to roll back to 4.3. Tried a factory reset etc and didnt make any difference

Cheers,

Mick
[Nexus 4 General] luisjoseb:
+1 I have the same Issue
[Nexus 4 General] Zehlek:
I had that, the only way for me to stop it from disconnecting was to leave the screen on
[Nexus 4 General] micks_address:
So if i were to upgrade again to 4.4.2 and then in developer options choose the 'Stay awake' option - the screen would stay alive when i receive a call in the car (i always leave in charger/holder while driving)

Is there an App available that will keep the screen alive just for call durations?

Cheers,

Mick
[Nexus 4 General] Rohit02:
Using Stay Awake option keeps the screen on only if you are charging and not while you receive any phone call.
[Nexus 4 General] micks_address:
Yes but as my phone is always charging in the car when i get a call i assume the screen will 'wake' then wont go off until either i unplug the phone from the charger or lock the screen manually?
[Nexus 4 General] Rohit02:
I doubt.. try and let me know..
[Nexus 4 General] micks_address:
This actually worked - i updated yesterday to 4.2.2 and in the developer options have set to stay awake when charging.. while driving with the phone in my broddit car holder its charging all the time.. so i can make/take calls hands free and screen stays away during the call.. and when i hang up i just have to hit the power button on the side on the phone to put the screen to sleep again.. at least it isnt dropping calls any more!

Lockscreen and keyguard Usage

Not sure this is the proper thread for this...just upgraded to KK. Previously, on JB, with PIN set as security and Automatically Lock set to 1 minute, the keyguard would present if turning the display back on under 1 min. With KK, it seems there's no keyguard under the 1 minute auto lock time...is this normal?

I see potential probs with this if it is...if I turn display off and place phone in pocket under the 1 min time, any wakelock, i.e. phone ringing, or accidental bump of power button, no protection of keyguard.
