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.
The Evo3D Killer!!!

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] Wrong stats on Bluetooth activity

Hello, i'm using betterbatterystats to check my battery life.
Everything is OK but i have a strange behaviour.
The App says that my bluetooth is always ON

}
but my Bluetooth is always OFF :
and i double checked in Parameters, and even restarted my phone, still same problem ....
Then today i checked my batterys stats and i get this :
My log is 19h10m5s long, and i have 2% of Bluetooth time.
But when i look at bluetooth time it says also 19h10m5s
so it should be 100 %, shouldn't it ?
Anybody also experiencing these strange Bluetooth stats ?
My Bluetooth is ON or OFF ?
Thanks.

battery stats doesn't really work, looking about the forums you see if you put wifi on all the time it says you have No or unknown signal for the same time as wifi was on.
you can look at your own screen shot for this one
seems it doesn't report as it should on the HOX

Hi, it is quite sure that betterbatterystats doesn't work but it's the system logs which is in fault not the app itself.
Even the stock app shows strange values on Bluetooth and wifi as you mentioned ...
In the case of the One X it is very useful to read those stats, but if they are totally wrong, how can we do a correct analysis of battery drain ...
By chance it is rarely bluetooth or wifi that drains the battery.

apagado es mejor!!!

19+ hours on battery with 65% left, and you call that a drain?

Hello, i have no drain, and never said that.
I just noticed those strange bluetooth stats when checking battery usage ...

Can you disable widget locker and associated power widgets in you home screens and figure out?
I would imagine some kind of interaction comes into the equation with these 3rd party programs.
Bonne chance.

Hello, thanks, it is a good idea ...
I removed the power widget on the home page and disabled widget locker.
I restarted my phone. Weirdly i had to insist to restart the phone.
When pushing power button, after 3 seconds, the lower buttons were blinking
but it didn't start, and then keeping power button 3 ou 5 seconds longer the phone restarted .
That is not the first time i noticed that the phone doesn't start or stop normally ...
At restart, i didn't see 100 % "bluetooth on" in betterbatterystats.
It looks like problem is solved ...
I will let the phone like that for a moment and put again the power widget on home page to see if i get the error back.
And then activate back widget locker.
Merci.

I activated the bluetooth for some minutes and turned it off.
Now i see on betterbatterystats that it is still ON in stats.
I refresh and the time "bluetooth on" is increasing.
I will wait a moment to see if bluetooth appears on "stock" battery stats.
It looks like a android system issue with bluetooth stats

If you feel you have found a bug in BBS I would be glad to help you clarifying what is wrong (or fix what has to be fixed). But please take the discussion to the right thread.

Battery Problems?

So i wake up and took my phone off the charger. I am at 100%, I use it for two hours, texting/facebook(a little)/instagram(a little) and had a 3 minute phone call. I have juice defender on and brightness all the way down. I am on DARKSIDE.EVOLUTION.3 [6.23.2012] [v7]. I lost 23 % in 2 hours. Something wrong here? Or is it just me? I get about 11 hours on my phone while at work, mind you, my phone is idle most of the time. No service for internet cause i am in a warehouse, so all i do is text if i am on my phone, but cant use it heavily. Yet my phone only lasts like 10-11 hours. Anyone can help? Thanks in advanced.

Yeah i had that same issue. First off, update to V8. Its smoother and you save a ton of battery. Turn governor to Badass setting with 384 as min (you can set max to whatever you want....kept mine at 1350).
Next turn off all automatic syncing for all apps....Facebook and GTalk is the biggest culprit of battery wasting. To be honest, you dont need automatic syncing for Facebook, mail, xda etc. another big killer of battery is loss of signal. I turn on airplane mode when i am going to be out of signal for a prolonged period of time. Oh and obviously...turn off wifi if you are not going to be connected. I also found widgets to be a source of alot of wakelocks which keeps the phone from sleeping properly and leads to battery waste.
Next part is up to you. I use a combo of GSam Battery Monitor, Better Battery Stats, CPU Spy, and CPU Sleeper.
-GSam Battery gives you a detailed breakdown of what is using your battery, how much, and tons of useful data including some wakelock data.
-Better Battery Stats gives you a detailed breakdown of detailed wakelocks. (you are aiming to get rid of the wakelocks associated with user apps, cant totally eliminate some but get them way down)
-CPU Spy gives you a detailed breakdown of CPU time in state and DEEP SLEEP

I am still trying to figure out the calendar and maps wakelocks. CPU spy is not reset from yesterday(doesn't reset on complete charge or unplug yet. Manual resets only)

Plagued by phantom GPS issue. am i alone?

OK, so here is the deal.
been having this same problem on a couple different ROM's, the latest one was the 4.2.2 GSM build "ported" over to my Verizon Nexus. i have ZERO issues other than this one.
yesterday, i tried using GPS to navigate, i wasn't getting the flashing symbol in the status bar (just the GPS symbol with nothing in the middle flashing) so i figured GPS was borked on this build....no big deal. i turn off GPS and go on my way.
later in the day, i check my battery stats, and see that Maps has been using most of my battery (about 40%) and after opening it up, it has had GPS ON, for 5 or so hours....even though it has been off the entire time.
so i Froze the "Maps" app with titanium thinking that might fix it.
charge it over night, with a reboot in the middle of the night.
wake up, go to work, place on charger again, pull it off once it reaches 100%
after 1 hour i see this.

dont worry about percentages, that is with streaming pandora the entire time, as well as 15+ minutes screen on time in weak 3g/4G signal.
remember, MAPS has been Frozen for the entire day!
so I click on MAPS and see this
again GPS was "ON" the entire time according to my phone. but its not on, and i haven't used anything that would use GPS (no maps because its frozen, no google, no FB/G+ ect.
so....am I alone here? Anyone else having this issue?
the only way i know how to fix it is to factory reset and re-flash the ROM. but i am afraid it will come back as soon as i use GPS again (rare)

This is why I un installed maps. Happened to me yesterday on an unmodified stock rooted rom. Kept my gps on for 6 hours when I never even opened maps app to start with.

Just moved over to a GNexus from my Inc2, installed AOKP 4.2.1 build 3 and my GPS is on all day. Goes off and comes back 5 seconds later. Its driving me nuts.

Is your gps turned off in settings? I usually don't have an issue until i have GPS on and the phone tries to find a lock. Doesn't matter if it's maps or Facebook or Google plus.
they all eat the battery and show GPS as being on for X amount of time

I think these are separate issues as i am never showing a gps icon unless i am trying to acquire a GPS location.

Yea, I figured they were but this was the only thread I saw close to the problem I was having so I figured I would see if anyone else out there was experiencing this as well. I can't for the life of my figure out what the hell is going on.
** Update **
Shazam was causing the GPS issue. When I added the widget it turned on GPS for location song tagging! Never had that issue before. Disabled the feature and all is good in the hood. That was fun.

Question Extreme Battery Drain Issue During Phone Idle (Poco F3)

I've been getting really terrible battery drain while my screen is off / during the night since forever and this is one of the worsts.

These are what I've tried so far:
Reinstalling the latest miui (12.5.2)
Clearing data and cache for the Battery and Performance app
Turning on Battery Saving mode
Many other little settings such as preventing phone from downloading updates at night
Turning off WiFi manually at night.
There has to be a culprit behind this, maybe I can rollback the miui update somehow? Thanks in advance.

Try netguard and limit which apps can access internet while screen is off. Also try running and completing the dexopt job once so it doesnt have to do it every time phone is idle.

Thanks I've done it and will see how it goes.

It seems like your Phone isn't fully entering Deep Sleep, could you show entire Battery Usage Statistics? Also do you charge your phone to 80% to save Battery Life or to 100%?

Mine was same. A soft-reset solved the problem. Hold down the power button (when the phone is open) and keep holding it until it restarts. Try a few times if it doesn't solve the problem.

Thanks for replying such an old thread!
Anyway, it was resolved and the culprit was the SIM card. Not sure if it was a 3g SIM (not my sim, so can't confirm) or that it was faulty, it was sucking a lot of battery which explains why it was fine when I turned on Airplane mode at night.
I hope this helps someone out there.
