Nfcwakelock gets stuck and keeps phone awake - Nexus 6 Q&A, Help & Troubleshooting

Anyone have issues with nfcwakelock keeping the phone awake? It's just a solid bar of awake in the battery stats. Turning off location or going to airplane mode will not kill it. Only a reboot will.
I'm running stock 5.1.1 with root.

You can turn it off, but you will need Xposed installed. You can follow this post on reddit.

CM9 NIGHTLY... always awake

I'm getting pretty bad battery life on nightly 21, so I checked out the battery stats.
It is showing the system as awake constantly, even when the screen is off, and in airplane mode. I'm using tasker, as I did on the last ROM, but even with it disabled, the system is always awake.
Any suggestions?

I was reading is a new update for the nightly's, so I'm going to see if it still a problem after that. But I would still appreciate some input from anyone here. This battery life isn't going to work for me.

Could help you find out what drains the battery.

Wifi Off when sleeping?

Anyone had any luck with the option to turn off wifi when sleeping?
I tried checking it, but it has a problem reconnecting when I wake the device. I have to manually toggle the wifi to get it to reconnect.
I'm trying to extend my touchpads standby time. I already turned off most syncing.

I've been having the same issue lately.
You could try an app called Automatelt it is very easy to use and there is a trigger for screen off/on and an action Wi-Fi off/on . I use mine to alert me and turn off my TOUCHPAD when the battery gets to various levels.
I hope this helps .
If you are using android, try updating your current build to the latest. Wiping Dalvik cache may work too.
Just did a clean install of 9/16, did the same on 9/3.

[Q] Phone is always awake (battery drain overnight)

So I got my One two days ago and installed some apps, running on stock 4.1.2.
According to the system monitor my phone is ALWAYS AWAKE, even when I turn it off and only plug in the charger.
How can I solve it, how can I find what app is keeping my phone awake? I am losing like 50% battery overnight while in airplane mode
Thanks, BBLN.
It's difficoult found the app.
So try with an hard reset or see in dev settigs if there is the voice selected

Nope, it's like my phone is draining while being idle (On battery usage: Phone Idle - 50%).
I closed some running services, seems like now he is finally really idle.

Doubts regarding Stamina mode..

Hi..I have few doubts regarding stamina mode.
1) Does stamina mode downclocks or shuts downs the core when activated? as in does it affect the overall performance?
2) Do you guys always keep the stamina mode ON or only when battery is low?
1. No, and no. Its job is to shut down processes that need internet connection from waking up when the screen is off.
2. On, all the time, with exceptions.

thanks for the link..i have gone through many articles..but wanted to know from user side..
I havnt noted any problems with stamina set at 50% and low battery mode at 30%, still works as it should right down into 10% although I never let it get that low, there is always a place to charge up, wi-fi on saved locations, BT on most of time and gps for navigation, I actually think the battery is fine for me at least

No.
Stamina mode keeps a whitelist of application that is allowed to wake the device for refresh etc. Other than those in whitelist, they can only be active when screen is on.
I noticed that when stamina mode is on my wifi and 3G both works..does that mean stamina mode is not working properly?
arpith.fbi, I think we have mentioned that Stamina mode does NOT stop wifi or 3G connection.

for your kind information mister i do look for information. I was confused coz the sony article says and i quote "Starting one minute after the screen has been turned off, data traffic is automatically blocked and background activities are prevented from waking up the system." taken from http://developer.sonymobile.com/2013/04/03/how-sonys-battery-stamina-mode-works/
I get all kind of notification when 3G and wifi is on even after minutes of screen off...thats the doubt..
And if you dont want to help the just dont **** on my thread.!!!
If all the information are clear for you that means your stamina mode is not working as it should,so not a doubt it's a problem with your phone or bug in 4.2.2 if you have it.

see this is called helpful information doubt and problem is narrowed down to 2 things..
fyi i go through 100s of articles and thread before opening up a thread over here.
I didn't replied your quote yesterday waited more users to give you more info,but you took all the information and you still asking that's why.
It was very easy to predict that your phone is misbehaving.
Anyway peace

Wi-Fi Calling Draining Battery

Anyone notice their battery going down the tube with Wifi Calling on? My phone has been off battery for 8 hrs, its at 58% and showing 33% usage for Wi-fi calling. The next closest thing is 9% for Blinkfeed.
I have the same problem too. I even turned off "Wi-Fi Calling" in Settings and "Force Close" it. However, the Wi-Fi Calling app is still draining battery

FYI. You can use titanium backup to freeze the wi-fi calling app to eliminate the drain until the fix comes out. You have to reboot after freezing

Thank you for the info! The app is no longer running.
That's very weird. I use it to save battery keeps the cellular radios off. Can go over 8 hours maybe 10% drain. Running captains stock rooted rom. It was a clean install. Make sure your firmware and radios are updated, do a hard reset.wifi calling has been working great for me
