Can't get NFC to turn off. It'll disable the tick box, but remains ticked if I try. Re-entering Wireless & Network & NFC is still Ticked.
Severe battery drain as a result, after 22hrs uptime, Battery Use shows:
NFC Service @ 61%
Display @ 15%
OK, think I may have figured it out. Had to force close the service, now finally appears i can untick it!
close thread. +1
glad you solved it.

I set up the WiFi standby rules to "never", so wifi should be always on even when my device is in standby mode.
This worked very good at the beginning, but since some days WiFi is NOT kept alive. As soon as the device is going into sleep mode i will lose WiFi connection. The WiFi standbye rule is still correctly set to "never".
Thats really lame because i use locale to update my RSS Feeds at home over WiFi on certain time slots. But i get no updates since wifi is not active when the device is sleeping.
Anybody an idea what the problem is? As i said it worked for 2 weeks and suddenly its not working anymore.
Won't that drain the battery to Kingdom Come if you do leave it on on standby? I used to do that on the Tytn II I used to have, and the battery died after 2 hours!

well i wouldn't say 2 hours, should be more than that. But i'm only activating wifi at home, and at nights my device is plugged to ac adaptor. So battery is not an issue in my case, and i want to use the better bandwidth at home. I just dont know why is suddenly stopped working...
Settings > Wireless controls > Wi-Fi Settings > Menu > Advanced > Wi-Fi sleep policy. When finished press Menu and then Save. Done.
The "Menu Button to save" Hint did it! thanks!
I always chose the option, but forgot to save via menu button and pressed the back button.
The strange thing here is: when i was coming back to this menu later it would still show the correct setting (WiFi always on), even though i hadn't saved it via menu button. But it wouldn't work, because wifi would be deactivated.
The back button will save your last selection, but won't activate the option!
This is really one of Androids problems: you just don't have one standard way of interacting with the system on many levels. Sometimes "back" button is enough (or the only way) to store your data, other times you have to press hardware buttons to save...
hmm the problem seems to be elsewhere: today in the morning the connection was lost again when i took the phone out of sleep mode. i could see the wifi icon, but the apps couldnt connect to the net (my rss feeds hadn't been updated).
Seems like each time i deactivate wifi manually (when leaving home) the wifi rules settings will be lost, and i have to change the wifi rules again and save the settings. Otherwise wifi won't be kept alive...that's really annoying.
maybe i have to download the "keep wifi alive" app after all from the market...
What make and model is your AP?
it's a netgear router, i will check the exact model today and post it here.
hmm i forgot to check the model, but i changed my router settings yesterday.
the router was set to disconnect after 60 minutes, when the connected device is not using the connection.
i changed that, so the connection is not reset at all, but still as soon as my device goes to sleep mode the wifi connection is basically dead.
After taking the phone out of sleep mode, i can see the "wifi connected" icon still there, but no app has any internet connection.
Hi folks,
I have been facing battery drain & deep sleep issue on my Nexus 4 which i have reported in my earlier post. After formatting couple of days ago, yesterday i noticed again the deep sleep & battery drain issue. I was totally frustrated & annoyed by the Google's 4.3 update. The above said issue persist only after 4.3 fix (1.8Mb) update, may be most of users facing the issue since then.
Here are few tips i followed to get rid of battery drain & deep sleep issue,
1. Menu - Google settings - location - uncheck location
2. Google settings - Google+ - location sharing - uncheck location sharing
3. Menu - settings - location access - uncheck gps satellite
4.Settings - wifi - advanced - uncheck scanning always available
5. Settings - wifi - advanced - wifi frequency band - select 2.4Ghz or 5Ghz based on router. Don't select Auto as wifi signal fluctuates often.
6. After following the above steps clear the cache, turn off the phone.
7. Wait for the battery to drain to 0
8. Charge the battery to 100% using the normal charger. Dont use any other fast charger, portable or wireless charger, as it ll have impact on battery.
Let me know if the above steps works.
Ps: The above settings are carried out in Stock 4.3 & not rooted.

Pranaam sarkar..
you have to check what app is draining your battery.. and what apps are preventing your phone from going to deep sleep mode.. There is a app called batter battery stats here in the aps section of android that will help you to find detailed battery statictics.. then you can use another app called grenefy to "shut up" the apps causing wakelocks..

The thing is, I kind of resent having to turn so many functions off just for my phone to work correctly. I mean, turning gps off and not being able to use navigation?
I have the android OS bug it seems, its draining as much as the screen is which isnt good.

Whats app is not causing any battery drain for me. The only culprit I have noticed is the Wi-Fi.
Anyways will download & try batter battery stats, shall soon update with post in couple of days. :good:

Yes, it's definitely issue with OS.
The only option available to us is to make some setting and maintain the juice till the next update.
So I posted this in a different thread but figured I would post it here to see if anyone could duplicate my findings. I have a Note3 from T-Mobile and for whatever reason leaving the Wi-Fi on will not allow the phone to go into deep sleep mode. I noticed when I was down to 40% battery after 10 hours with only one hour of screen on time. After running some tests I had only 2 minutes of deep sleep those entire 10 hours (tested using BetterBatteryStats) I tried setting "Keep Wi-Fi on during sleep" to Never and unchecking "Always allow scanning" under advanced network settings but neither of them fix the issue. In fact, after several tests I concluded that setting never for "Keep Wi-Fi on during sleep" wasn't even functioning as my access points still showed the client connected while the phone was asleep.
Can anyone else confirm this issue is actually a bug and not just my phone being defective?
Here's my original post on the topic regarding how I found the problem and what I have tested so far:
OK so after only 2 days of owning this phone (got it late Monday night, the T-Mobile variant) I finally figured out why I'm getting such bad battery, and I suspect the same thing may be happening for the other people in this thread. Hopefully this information helps at least one person.
My battery stats was almost identical to all the other users in this thread that had bad battery, I would get barely around 10-12 hours on the phone with less than 2 hours of screen on time. After using multiple apps to track down the issue I finally got what it was.
Wireless. Yes, wireless was my cause. But the thing is Wi-Fi didn't show up at all in any of the battery apps so I assumed it was a non issue. I've had other phones and have always kept the wireless turned on the entire time without problems. The basic problem is not that Wi-Fi is using power itself but it's that by default the phone cannot enter deep sleep while connected to Wi-Fi. This is why trying to use apps like BetterBatteryStats will lead you nowhere initially (though they were useful in finding out what was causing the issue) You can discover this by turning on Wi-Fi and connecting the phone to a charger, then disconnecting it so your BBS information will reset. Then power off the screen and power it back on after 10 minutes. You'll notice in the other section that deep sleep will have less than a minute time while awake probably has close to 9 minutes, if not more. This is with everything else turned off, almost no apps, and no special Samsung stuff enabled.
Under Apps > Settings > Wi-Fi > Menu > Advanced there are two options that should help this: "Keep Wi-Fi on during sleep" and "Always allow scanning" I set the "Keep Wi-Fi on during sleep" to Never and unchecked Always allow scanning and rebooted the phone. And low and behold...nothing. Yes, these options don't work (at least not to fix this problem) The phone still won't enter deep sleep mode while the wireless is enabled. Based on my company's wireless devices I can see that even with the screen off for well over 10 minutes it still shows connected as a client meaning the wireless is not turning off properly while it's in sleep mode. Or perhaps it can't go into sleep mode because the wireless is on which stops it from going into sleep mode and turning off the wireless. My guess is that it's a Samsung bug.
The reason why there's so many people here to get good battery usage is because they're either used to turning Wi-Fi on only when needed and keeping it off. You'll also not notice it if you have more than 6 hours of screen on time because you could easily assume that it would make sense that you phone would only last 10 hours total with that much screen on time, even though it should have technically lasted 20+ hours with only 6 hours of screen on time if the phone could have entered deep sleep.
So what's the real fix for this? Unless it's by design my belief is that it's a bug and won't be fixed until Samsung/T-mobile notices. I can't test to see if the same thing happens on other carriers so if someone feels like testing this theory out it would help.
For now, I guess we're just left to manually turning Wi-Fi on only when needed and leaving it off in all other cases. For those that have the T-mobile variant, make sure you also go into Settings > General > Backup and reset > Collect diagnostics and uncheck the "Allow Diagnostics" as that will probably be the highest offender of Partial Wakelocks (it'll show up as com.carrieriq.tmobile.wakelock or System Manager Application)
If anyone wants more information on my testing let me know!

That's because the 'Keep WiFi during sleep: Never" setting only disconnects, it doesn't shut down the WiFi radio.
You're going to have to use a manager (Like Deep Sleep Battery Saver).
Or just hit the toggle yourself... If you're going to keep it disconnected in sleep anyway, just swipe down the notification bar and hit the bloody toggle.

The problem is that it doesn't disconnect, the access point 100% shows it is connected and transferring data every now and then. But the real issue isn't weather it disconnects or not but it's the fact that Wi-Fi will not allow the phone to go into deep sleep mode. For now I am fine with switching Wi-Fi off and on as needed, but with no other phone have I needed to do this before and definitely seems like a bug.
But regardless, what I'm trying to figure out if this is a legit bug that I should submit to Samsung/T-mobile or if it's just my phone and I should ask for a replacement. If anyone has BetterBatteryStats and could test this with their Note3 that would help.
My stupid phone has just started this same issue!!!! Freaking annoying, after only 8 hrs from 100% charged state, the battery is at 46% with only 26 mins screen ontime, I checked out that the phone never goes into deep sleep. What is going on and what can be causing this? Did you manage to resolve your issue?
PS I checked out wakelock detector but doesn't tell me a thing, as what program is keeping the phone awake all the time. Starting to hate this phone and miss my S3
What is your GPS accuracy setting set to? GPS, Wifi or Networks? Try setting it to GPS only.

Well, your issue looks pretty similar to mine, which I solved with this Xposed mod (you could give it a try if you're on KitKat): http://forum.xda-developers.com/xposed/modules/mod-wi-fi-deep-sleep-t2752947. I was experiencing that even when "Keep Wi-Fi on during sleep" is set to Never, Wi-Fi still was awake most of the time according to battery stats.
Hi
I recently noticed that my battery life has been better then recent days
I opened up the battery screen and found out that it shows as if the wifi is always turned on (picture attached)
Doubled checked that the wifi symbol is grey + checked the wifi section on the phones' settings
Have any idea what can cause the problem?
Thank you
Open wifi settings/ menu /advanced settings/ and check the wifi sleep state. I have mine always on as I spend most of my time in a wifi environment.
If you set it to sleep when screen off you will see it in the battery state screen you've referred to.
I personally don't find any battery benefits from sleep when screen off but try it for yourself. Your situation might be different.

This will turn off the wifi while sleep if the wifi is on generally. What I'm referring is that my wifi stays on (with no connection, just drains part of my battery) even after I turn it off
There are several settings menu settings that pertain to wifi. Disable the settings that allow Google to check wifi status even when wifi is off, automatically search for new access points and never sleep.

Hi guys
I noticed countless times that randomly when turning on wifi and then turning it off, the "always allow scanning" under advanced options is ticked.
I noticed this because then under battery usage you will see wifi active even tho main switch is off and 99% of the time that is why.
Is it a lollipop 5.0 bug or is it some of my apps that can switch that option when they detect wifi has been activated?
Also, it seems that if i dont turn on wifi in the first place, that option never becomes active. Battery life is very good on my phone so not a deal breaker....
Anyone knows?
Thanks
