[Q] Dialer app causing battery drain

Hi all,
So I recently took my trusty N4 running CM 10.1 w/Matr1x 9.5 all the way back to stock.
Used Wug's root toolkit app (great stuff), downloaded the 4.3 factory image from Google and took the phone to a completely stock version -- lost root and custom recovery in the process (as expected).
I have since rooted and added TWRP. The only apps using root at the moment are Auto Hide Soft Keys, Better Battery Stats (XDA ver), Busybox free, Greenify, and Quick Boot.
TLDR: N4 is Stock + Root, running 4.3
With the phone all set up now, am facing a weird battery drain issue.
The app that takes up the most battery is the DIALER app. I've attached screenshots from right now showing how the dialer is #1 draining battery (ignore the high battery life, this is from overnight when the phone was barely used).
Over the past week the general trend I'm noticing is ~12-14 hr of usage (normal usage of calls, browsing, email, all sync enabled; phone dies at this point), dialer shows CPU total 1h30m+, with very little actual foreground time. This is a far cry from the 15-20h I've generally gotten from this phone (whether stock, AOKP, CM etc, same usage pattern).
A friend of mine suggested that maybe the proximity sensor is keeping the phone and dialer app awake constantly. I used the Proximity Sensor Finder app which showed me that the proximity sensor was working. Playing with the proximity sensor in this way seems to reduce the CPU usage of the dialer, and improve the battery life.
Questions: Hardware or software issue? Any other way to debug/test what is broken?
Any thoughts, ideas, suggestions are welcome.

Any one have any ideas?
My battery stats today morning: Phone at 80% battery level after 1h 35m, with dialer at 51m 6s usage.
Seriously wondering if this is RMA material.

Have the same problem with my n4. Stock rom 4.4, rooted. Drives me nuts. All of a sudden dialer sucks my battery empty.

I'm not sure but I think you may use Greenify Xposed Module (donation pack) which makes you can hybernate system apps.
You could use it to hybernate the dialer.

[Q] Android OS accounting for a huge part of battery usage

Hello all.
First off, bear with me if this has been discussed before, I have searched on google and in previous threads here (including the amazing 58.5 hr standby and 6 hr. usage thread) but I cannot find the culprit of the huge Android OS drain.
The battery lasts about 4.5 hrs of screen on time , which is pretty neat but nowhere near what other people are reporting. I know the battery needs to go through a few cycles before reaching its full potential, but the Android OS drain is what bothers me. Please note that I am unrooted due to warranty issues and an unreliable rootchecker.
I have done the following:
Disabled bloatware
Disabled LG MIT (P.S Do you recommend me to change other settings from the hidden menu?)
Disabled auto sync and backup in the settings menu.
Disabled Google Location services from Google Settings, although I kept the location settings in the settings menu due to widget.
I installed Lux to prolong battery life and it only operates upon waking the device.
Installed BBS and Wakelock detector
BBS shows 154 partial wakelocks in just 3 hours of standby from WifiOffDelayIfNotUsed and NetworkLocationLocator 191 partial wakelocks.
Wakelock detector shows a fair amount of Facebook wakelocks (86 in 3 hours - could that be the culprit?) and Viber with 21 wakelocks. This makes me miss Greenify - damn!
To round this off, can anybody please give me advice on how to solve this drain? As previously mentioned I am not willing to root it just yet. Feel free to include perfomance boosting tips as well if you have any
Thanks in advance.

I don't know how to solve the problem, but I can tell you this regarding root: Flashing a KDZ file after doing a full factory reset makes the roottripper reset too, including a showing of UNROOTED in the download mode.

Awesome news! Makes me reconsider rooting my device. I would still want to know what I can do without rooting. Thanks a lot for the info ?

Use Better Battery Stats to see exactly what is causing wakelocks and GSam Battery Monitor to see what's using other things.
"A huge amount of battery" is meaningless without context. If it says "50%" but that's .5%/hr, it means NOTHING else was doing anything really.

Disable KnockON, then Android OS will shrink to a few percents in your statistics.
I have tested it out, KnockON is causing the most part of Android OS.
Via LG G2

Wifioffdelayifnotused can be caused by going in and out of service. Disable optimizing in Wi-Fi, disable disconnect on low signal, set sleep policy to never.

well. As stated in OP I am using BBS but I will try out Gsam battery.
You've got a point there, but I'm not seeing 24 hours of standby, which annoys me. A side note- if there was no' something' draining my battery wouldn't it show as "device is idle" rather than android os?

Thanks for the tip. I am well aware that knock on uses up some battery but I don't recall the people getting 6 hrs of usage and 50 hrs of standby disabling this feature. Anyway I wouldn't disable this feature even if it would give me am extra hour of usage (unless in dire need) ??
And to the last post (which I forgot to quote) WiFi is set enabled in standby and the other option is disabled. The only thing I have checked in the advanced WiFi settings is lower battery consumption when device is using WiFi. Thanks for clarifying though.
It seems like. Android os is a mystery ?

The cpu power consumption is the biggest problem~
I had read a Chinese thread that CPU quality is the major problem causing this huge battery drain. Qualcom classified 7 quality levels. Slow, nominal, fast, very fast, ultra fast,....from class 0 to 6.(higher is better). the higher class quality means that cpu can use lower voltage to reach higher frequencies. The difference between C 6 and 0 is about 0.15V,,, :crying:
PS: [email protected](0.95V Max)/ [email protected](1.1V Max)

There has been some improvement but the phone was awake for 42 minutes more than screen on time . I posted some screenshots.

I'd say leave wifi optimization, set sleep policy to any other than never, and turn off the feature that turns wifi off if the access point you're connect doesn't have internet access. Or try aosp

If you're connected to more Wi-Fi than cell signal, leaving this on will do nothing to increase battery usage, more so increase it. Counterintuitive, but it is what it is. This is Google software itself, not hardware. Learn before you post BS. The phone uses more battery searching and refreshing for 4G data signal than it ever will on Wi-Fi. Do what this guy says if you spend most the day in Wi-Fi, and watch those counts hit the roof. If your of Wi-Fi most the day, just turn it off until you are, all good. Why waste battery when unneeded.

Google Now Widget causes significant battery drain

Just wanted to share my experience.
Found my N7 battery was draining significantly while it was sleeping. As an example, I would lose over 10% overnight with the N7 off the charger. Hence I was having to recharge my N7 every 2 days, even with little use.
After Googling the problem, I tried various things like setting WiFi to "never" be on while sleeping (advanced setting), turning off location reporting within the Google account, turning off location history, etc.. All very common suggestions but none of them helped me.
I then removed the Google Now Widget and Voila!
I have now re-enabled location services and Google Now is still available by swiping up from the Home button. Battery drain while sleeping is back to just 1-2% overnight.

Lollipop battery drain

I got the German 5.0.1
IS it only me or is it general with the battery drain?
Even in Flight Mode, I am losing the battery in a couple of hours

Hello everyone, two days ago i downgrade to kitkat, I decide to re-put Lollipop because I'm documenting on various forums Italian and foreign, and this drain the battery does not have all .... well for my case I installed the GSAM Battery Monitor from Play Store that seems to work well with Lollipop. I left the phone idle and discovered that the deep sleep has never been reached. The phone was always active, even when locked.
GSAM has reported that the app "Unified Daemon (EUR)" was among the top three applications that consume battery.
According to various forums is a preloaded application from Samsung that unifies information like weather across other applications preloaded. I really do not know what good has this application.
I tried to turn it off, and in fact the phone goes into deep sleep with consequent consumption "standard" like KitKat.
The downside of disabling this app is that you lose the weather from the lock screen and through the window of the cover S-view, while the widget on the home seems to work perfectly.
Obviously there is to say that others should do the same test and see if this app will appear among the first applications to battery consumption.
A greeting

disable Facebook app (use web version) and turn off wifi when not being used. My battery usage has transformed! See other thread....70% after 10 hours. 56% after 13 hrs! Lollipop is buggy. Manage wifi manually and you're battery will be awesome.

^^^^this^^^^ . Me too. Disabled damn Facebook and it a few Google apps and I'm back to normal. The main culprit is the stupid Facebook. To make easy access of it from Web just make a shortcut on your desktop.

I will leave wifi on today regardless of whether or not it is connected and see if things get warm / battery usage ramps up. If it doesn't it might indicate an issue with FB alone or at least prove whether or not wifi is stopping the phone from going into deep sleep after a period of non use. Yesterday having left FB and wifi off, resulted in 40% battery remaining after 16 hrs usage. It never got hot once. This is my yard stick.
Lots of users are having issues with the latest update to facebook - just look at the comments on the play store!
Anyone else been having high battery usage but are not users of FB app on lollipop?

@gasland Here is what i did.
I uninstalled
Facebook, Facebook pages, Facebook messenger and com.facebok."something"....
I removed everything that had the name "facebook" and rebooted my device.
Battery has been okay since then.
Ps: I also froze "unified demon" as I don't use either of the weather services or finances or all that crap.

Massive wake lock and battery drain

Hi guys,
I have been having an issue with my Motorola X Play (UK Single Sim) I have only owned it for a few months from new.... The battery is draining fast and I can see in the battery stats that it's not sleeping, otherwise the battery usage page shows nothing of interest, apart from perhaps Mobile Standby which is quite high, above the screen but the signal bar is all green...
I rooted my phone to better find out what was causing these issues, otherwise stock Marshmallow. Unfortunately Motorola now are not interested as they say my phone is rooted and now has no warranty - useless idiots!
Using GS Sam battery monitor (rooted) I can see that the following is keeping the phone awake, no other app is.
48.3% of battery consumed by Kernel (Android OS)
Keep awake over 2 hours
CPU usage 59m 53s
Number of Wake Locks: 1
Byes sent: 246.21KB
Bytes Received: 5.70MB
App UID: 0
Wakelock Detail:
Google_C2DM 0.0s (1)
I have tried safe mode but it appears to be the same, I have hardly any apps installed apart from Facebook and Facebook messenger and I have even tried it without them...
I have tried turning off/on WiFi / Location / GPS is now disabled. WiFi Scanning is off. Restarts make no difference... I have even done a factory reset about a month ago.
Any ideas, this phone is having the same battery life or less than my Nexus 5 which had a much smaller battery...
Many thanks

here's a way to avoid it http://forum.xda-developers.com/galaxy-s2/help/google-c2dm-checkin-services-t1321520
i'll update if i find anything else.
don't tell them your device is rooted. if you go to service center just re-lock the bootloader and its back to normal.[it won't get your warranty back but they don't check that much]
can you post a screenshot of gs sam.

1 - Install BetterBatteryStats (BBS) - this will give you detailed information on what is draining your battery. Get it from XDA v2.2.0.0B6 - this gives you the detailed breakdown in the UI that you are after, the google play version doesn't do it in the UI (older version).
Get baseline results (charge it full, don't touch it for 5-6 hours) I like to do this while sleeping.
2 - Install Greenify (you don't need the Xposed module if you don't want to fiddle with that yet, alto I highly recommend it) set the working mode to root. If applications are still not sleeping, add the widget and force sleep everything before you turn off your screen
Get BBS results (do the 5-6 hours while sleeping) - improved?
3 - Install Naptime from the google play store (by Fransico Franco)
Get BBS results - improved?
Getting anal about battery usage?
4- Read up on Amplify - this yielded even more results for me. But this can take a bit of work to get right. There's a lot of great threads on XDA for setting this up.
5 -Smart network - allows you to control data, networks, wifi, bluetooh, nfc, gps on/off with a ton of great features for auto. management.
I have all the above and yield a 0.4%/hr drain on stand by (see signature for phone build).

Amplify is a god sent app. It has been 4 hours now, and I have been using whatsapp on and off (about 20 seconds each time) and I still have 97% left in the tank.

Facebook app has been known to cause serious battery drain in the past. Uninstall it and test again.
In 99% of the cases it is caused by an app. Try to find out which one is causing the drain.

Hi all,
Sorry for the delay and thanks for the replies. I performed a factory reset again, after clearing the cache etc, the same as I did last time. The only difference is I then installed Android 6.0.1
The battery drain has now gone. I didn't perform a restore of apps etc, and the only apps I have installed so far in addition have been Facebook and Facebook messenger but I have found these have had no effect at all on the battery drain. I haven't even updated the stock apps (apart from the security ones).
I now get two days of use easy. It also seems to be running slightly faster. I will update apps one by one, over the course of a few days to make sure nothing causes it again...

http://forum.xda-developers.com/android/general/guide-extreme-battery-life-t3095884
I use this guide, works really great to limit wake locks.
And I don't use Fb app but use the browser instead, battery lasts easily two days of "heavy" usage !

I found the problem, or at least a major bug. Whenever you cast to Google Chromecast Audio and then stop casting completely there is a massive wakelock until you next restart the phone. My phone was awake all night and down to 20% battery life. Android OS takes a massive portion of the battery life and under keep awake stats it's 9 hours +. It seems that when it says disconnected it is not. A major bug! I'll try and report it using Google's bug reporter...

not even Doze could kill it? perhaps you could try Servicely and see if it could stop the thing from running.

Nope, Doze had no affect at all but it should be as it was sitting stationary overnight - normally the drain overnight is a few percent at the most, last night it was around 65% and I was left with 20% in the morning and this was I think the first time I had used Google Chromecast Audio since the factory reset with great battery life up to last night... I could try Servicely but I am not sure on the service to kill and I'd like to keep it 100% stock for now so I can help out Google to fix the bug (or Motorola if they bother)... What a pain as I just bought 4x Google Chromecast Audios!!
I have reported it here in the Android bug tracker, feel free to comment / star the issue to bring it to Google's attention.
https://code.google.com/p/android/issues/detail?id=208324
However I am not sure if this is a Motorola Issue or a Google Marshmallow / Chromecast issue?? Motorola support have been very unhelpful so no luck if that is the case...
If anyone else with Chromecast Audio could confirm the bug that would be great.
Thanks
Laurence

There's a post on reddit about battery drain with chromecast audio about a year ago, not sure if it's the same issue though.

yep
