WiFi Scanning constantly

I have been having poor battery life since I got this device on launch day. I just noticed today that my Wifi is constantly scanning even though it is connected. I usually keep Wifi on most of the time since I have really slow 3g at home and the building I work in is like a concrete bunker built in the 1970s so nobody gets very good service in there.
Anybody else notice this?

Yeah mine does this too but my battery life is still good.

this is also happening to me, and it is KILLING MY BATTERY!!!! really frustrating.

What do i look for to notice if its scanning constantly? is it the popup that comes up? with the networks that are in range?

i installed a free app called "watchdog lite", and it notifies me everytime my cpu usage goes over 50%, and at this time, i open watchdog, and it tells me "android system" is using 90%+ of the cpu... <<-- this happened EVERY 5 MINUTES when wifi is on. with wifi off, this only happened once in a while, maybe once every couple hours...
screenshow below: the critical battery drop happened when i turned on wifi, and CPU usage was going over 50% every other minute, and i restarted phone...
btw, this wifi issue does NOT happen when the phone is connected to a charger

I've noticed this as well and I believe its also negatively impacting battery life. Its interesting that it would continue to scan while its connected.

I posted on this earlier this morning. My wifi also turns off after about 4 to 5 minutes. I can toggle it off then back on ever time but this can't be normal.

Mine as well. Exchanged one for that reason and this one does it too.

I'm hoping we get a fix for this soon.

Same here..

I see it now....damn never looked there actually. So is basically a bug.

Fixed yet?

I think multiple people (myself included) have confirmed that this was normal behavior - it scans constantly, yet there's no battery drain associated with it.
It seems that whenever you are on that Wifi settings page, it keep scanning constantly. But when you leave the page, it stops doing it that often (or at least doesn't drain the batter.)
You can check that by turning off wifi and still noticing big drain - which would indicate that wifi isn't the issue.
Now, there may also be a bug where this constant scanning actually continues. But like I said, it doesn't do it for everyone.

Use y5 battery saver from the market. It turns on and off with known networks and helps alot.

My wife's is doing this and it is definitely affecting battery. Viewing the battery graph, it does a decline of about 30 degrees with only 3G on and with wifi on it does a treacherous drop of about 50 degrees. I've actually told her to just leave 3G on all the time because it is easier on the battery. Hoping for a fix soon.

Mine scans a lot but doesn't hurt the battery. With moderate use im at 50% with 12 hours on.

Anyone else getting Wifi connecting and disconnecting about 5 to 10 minutes.

Check your wifi sleep policy.
Samsung Galaxy S II

J-u-i-c-e d-e-f-e-n-d-e-r

If you want to try something, change WiFi Sleep Policy to *never*.
It seems counterintuitive, but the bug where Android system uses a lot of CPU uses much more power than setting WiFi Sleep Policy to never as the WiFi is using very little power when not transmitting data while Android system is just sucking up your battery with this bug.

[Q] Can someone take a look at my batterylog?

A couple of days ago I noticed my phone partying on my precious mAh's, it won't even last a full day anymore and even though it's being used quite alot I haven't changed my usage and still got a full day and more earlier.
I have auto-sync, wifi and 3g on constantly. But facebook sync is manual, other than that it's just skype(only when I'm logged in) and whatsapp and ofc google services. I think all Google's stuff uses push? I can't find any sync settings for that.
I should add that removing the widget was the first thing I did when I woke up so no actual usage is in the battery log. After that I checked tapatalk for 5 mins and put the phone down, after 20 min battery was down to 60% just like that...
I don't get why it uses around 40 mAh for a minute so often, at one point it was up to 162 mAh. And what the hell was it doing at the end? 60-100 mAh for a full hour? And only because I stopped it, could go on for alot longer I guess...

battery stats
Hi that is weird coz ur stats were excellent up till 8.20 ish, how about adding the 'Log running applications' setting in current widget to see what's turning on and draining ur battery.

Okay, I'll run another log tonight. Too bad the log gets like ten times harder to read with that option.
Sent from my Desire HD

u could see it urself aswell btw, in current widget, go to analyze log and select top processes, itll tell u what is draining sorted with the biggest power consumer. from ur earlier log standby should be at ~4ma and whatever is at the top is ur culprit. but post the results anyway just to be sure

I can't find that option? Anyway tonight it was a mess: EDIT I somehow didn't see the update in my apps...
The top of the list reads: com.cyanogenmod.cmparts(what's this?); gentle alarm(gotta have this...) and audiowidget(I don't even have the widget on a homescreen)

CMparts is cyanogen settings,
audiowidget is the audio manager app -https://market.android.com/details?id=com.smartandroidapps.audiowidget&hl=en
u need to remember that android has a memory management system which doesnt shut apps down immediately and only suspends them, it does this for quick recalls of a recently used app. when the phone needs more memory for a bigger app it then kills of the oldest recently used app, to free ram. you can use the task manager to kill apps off manually but not recommended since it may or may not destabilize android itself.
As for the battery drain, its actually very good, u lost 1% per hour with all of those apps running. The spikes that happens is just the phone syncing background data such as facebook, foldersync, etc as well as standby apps such as viber and go launcher activating from when you actually waking the phone up from suspend.
Google does use push sync, if this bothers you u can shut it off from Settings > Privacy > untick backup my settings - note that this will wipe backed up data and application history from google servers and not ur phone - doing this wont wipe calendar or contacts as that belongs to gmail.
if u actually notice on current widget during idle the phone sits between 1mA to 5mA. this is the expected range, now say if u open facebook it should spike up, on mine this spikes up to ~263mA for a while till it finishes downloading.
Wifi is another cause as well, since it usually disconnects after a certain period unless u specify the wifi to never standby, it will use up power to scan for the signal every so often and then reconnect.
Apart from that ur battery consumption is excellent. you can expect to use the phone regularly (browsing, calls, etc) w/o charging for a couple of days.

Thanks for an excellent reply. The thing is it usually lasted a full day and with around 30% left. Now I need to charge it around 9 or 10 so it's a couple of hours short. I use my phone alot, about an hour of music, constant wifi, games, Tapatalk, browsing and lots of texting. I was actually surprised it lasted as long as it did and even if my battery life is good now it was alot better before.
I have noticed that sometimes, say I've just exited and game with 80% left. After five minutes it can go down to 70%, don't know if my indicator is failing or my battery is crazy.
Btw wifi policy is set to never.

Horrible Battery Life

It would seem that after I installed the AT&T update to dumb down thr search on my phone, my battery life has been terrible. Yesterday it was down to about 30% after only 4 hours of light use with the processes "Android OS" and "Cell Standby" taking up the most battery. I can't even get through the day with this phone. Some help would be much appreciated.

After any update, give it a couple days to level out. Until then, just carry an extra charger and plug in when you can.

The update was installed at least a week ago.

In that case, backup everything and do a factory reset when you have a fully charged battery.

Alright I'll give it a shot. I needed to do that anyway as my clipboard no longer works and consistently crashes. :/

I did a factory reset a few weeks ago and that solved it for me.

Do you have any specific methods for backing up a phone that isn't rooted? I've got nova backed up, but I would like to make sure everything else is too.

Are you receiving push email? that was the major drainer for me. apparently the android email app has a bug.
Regarding clipboard...delete everything in data/clipboard; force close the 'test service' app and then restart your phone

The best method would be to use titanium backup but since your not rooted I don't know what options you have except to use the google backup but that ain't to good since its only app data.

Hi all,
Since getting the phone from day one, I really never had a problem with the battery. Lately however, I've noticed a significant drain in battery over night. I tested the drain a few times over several nights, and even put my phone into "airplane" mode to help save battery.
Below are my results from going to sleep at 1:30am with 100% battery power and in airplane mode and waking up at 9:30am the next morning. I get a 12% decrease in battery over night for doing nothing over the course of 8 hours.
The only thing I've noticed differently is that Chrome is starting to use battery which is odd because I rarely use Chrome to begin with.
Any ideas to help this? What should I do?

Yeah I've noticed a huge jump in Android System usage since I flashed the UCLG1 update.
Currently
18h 27min on current charge
screen on 1h 22min
Android system = 51%

DudeWatsThat, thanks I'm going to give it a try and see if uninstalling Chrome changes anything. It just boggles my mind that in airplane mode over night it would drain the battery 12%

Yea its definitely a rare bug since Chrome wasn't even displaying cpu usage.

i second that problem about Chrome. I think it is a bug regarding the builtin flash code. my battery was great until i installed Chrome then it got really bad. I uninstalled Chrome and my battery life jumped up big time. huge different. too bad i really like Chrome but no go right now

Not sure if it's the same issue, but I had some problems with battery life in Chrome until I disabled Tilt Scrolling under Developer Options in the Chrome menu.

my battery life is great even after the update

From previous posts on Q&A thread:
My GS3 i747m lasts around 50-55 hours per charge cycle..
It is running stock Rogers GS3 ICS, not rooted, all stock. Battery is stock as well.
Not using LTE, using HSPA+ ("4G") with data turned ON with Sync turned OFF
(**NOTE: sometimes, the battery is drained due to poor reception, and the phone will use more power for the cellular signal.. In my case, my 3G connection in my area seems alright for the most part, about 1 bar less from full)
Power saving is turned ON. WiFi powersave is turned ON.
Moderated WiFi usage in 2.4ghz 802.11g-mode only.
Every night when I go to sleep, my flight mode is turned ON. (I sleep around 9-10 hours everyday, so the phone stays on flight mode for 9-10 hours a day)
In the morning, I turn the flight mode OFF.
Bluetooth, GPS both are turned OFF
Screen brightness turned 1/4 brightness
LED notification turned OFF
Also, I have a task killer killing ALL BACKGROUND SERVICES every half hour.
Without killing all the background apps, my RAM usage is around 600-700 MB out of 1.6 GB of RAM
Killing all the background apps brings the RAM usage to around 360 MB of 1.6 GB
Without killing background apps, my battery life is shortened even when the phone is on standby.
Do this, and your battery life is pretty good..

Please stop killing background apps because it's really pointless. If you want to increase your battery life, the first step is to use BetterBatteryStats to diagnose wakelocks and ensure that nothing in the background is chomping up precious mAs while the phone isn't in use.
After that, disabling always-on mobile data is basically the best way to ensure that your battery is stretched as far as possible for use in standby.
When in use, only using LTE for when you really need the extra bandwidth will save a lot of battery. So will using all black wallpapers, using dark themes for icons, Touchwiz, and applications. Another really useful way to save battery is to use Samsung's browser background changer that you can use to make websites have black backgrounds if you need to save even more battery while in use.
Of course, after just eliminating partial wakelocks, you have to give up a lot of time and effort in order to reduce battery drain while the screen is on, while trying to reduce battery drain while the screen is off will require losing a lot of "smart" in smartphone.

High battery drain for a fresh reinstall 7.0 in idle for no apparent reason

Hello, people!
So, on 6.0.1. stock ENcrypted it was like this:

about 5% lost per night
WiFi always on, whatsup, maildroid checking one imap mailbox for every 120 mins (set to wake up the phone), ok google OFF, now cards OFF, backup-ing OFF. Steady about 5% (4-6%) per night.
Now, I flashed factory image 7.0.0. everything stock. Then I flashed boot.img with disabled encryption and formated data and cache. Everything is as it is described above expect for the maildroid has NOT been even installed yet.
And that's what I get second night in a row (rebooted, cache wiped from recovery mode before leaving the phone):
23% eaten for doing ABSOLUTELY NOTHING!
What even worse, even android itself does not know what it was doing that it ate so much battery because the percentages does not add up for the whole drain.
After so many time invested into this phone for getting pure stock 7.0 unencrypted I just feel exhausted and want to throw this phone out of the window.
I'd appreciate a right direction for figuring out what drains the battery.

Yeah battery blows with nougat. Significant Google play services drain mainly bet scheduler. Had somewhat similar with MM but was able to really calm it down with Power Nap, bit since Xposed is not out yet for N....I'm nandroiding back to MM too.

I downgraded to MM, and it became normal. The next day I missed the quick switching between the last two opened apps and I flashed N again))
Actually, this night it drained 8% what is kinda OK. What I additionally did was that I disabled under google account sync everything except for the contacts and calendar. Also I activated data saver and added only whatsup there. Wifi was on all night, but he phone did not seem to be waking up during the night at all, what is good because I didn't need it to be doing anything except for idling in case someone calls for emergency. So, I guess after some hard tweaking and disabling things I can cope with N, but mostly for the sake of awesome interface features.

Just give it sometime...things are settling in...so a lot of time play services and stuff also go crazy...also apps are getting updated as well...give it a week or so...things will be better

I had this sort of issue on DP5 after a while but clean flashing MM stock and then re-OTAing to N seemed to fix it for me and I'm back at 5-6% overnight.
I honestly think there is a bug in there somewhere, whether its Google services or what i've no idea as my battery stats didn't seem to add up to the drain I was seeing. I had a similar weird drain before on MM too which a wipe sorted out.

give the system some time to settle in. i upgraded to N the day it came out and after giving android a few days i recognize no major difference in performance or battery life, even though things like Force Doze are incompatible now.

That's a new data saver feature being turned on. Setting -> Data usage -> Data Saver option there

I went back to MM not because of the idle drain, infact, I had no drain but the SOT sucks... Like 2-3 hours instead of 4-5 on MM. Maybe I'll wakt until Xposed it compatible again...

Hi, I don't mean to hijack the thread, but I posted about an issue with the screen, which is battery related as well. Actually when idle I have almost no battery drain (up to 2% per night). Could you take a look at this thread regarding the issue: http://forum.xda-developers.com/nexus-5x/help/nexus-5x-android-7-screen-battery-usage-t3463591
I have screenshots prepared (even worse than what I've already described), but as already mentioned I don't have enough posts in order to be able to post them here.
Is this an issue with the screen, battery or OS? The device is new with the OTA Nougat update.
