Hi all,
The Wifi on my SGSII is constantly scanning even though it is connected to my home wifi network (a WPA/WPA2 PSK secured connection on a G band router). The signal strength is "excellent" and I have the phone sitting right next to the router. Further, I have network notification turned off ( unchecked) and under advanced settings, my Wifi sleep Policy is set to "never".
Sprint users have reported exactly the same problem on the Epic Touch 4G" (http://forum.xda-developers.com/showthread.php?t=1272226 ). Has anyone else been experiencing the same issue on their ATT SGS2 ? I would be very grateful if someone could post a solution for this issue.
Thanks in advance
J
PS: My wifi setting screen looks like this genteman's ( except i have network notification turned off)

Scan rate is bumped up significantly when you're in the settings menu.
Have you confirmed via logcat that it's scanning frequently outside of the settings menu? It shouldn't be in that case - but without logcat it's almost impossible to tell.

Entropy,
What should I be looking for in logcat? I have Betterbattery stats installed and according to that, Wifi scan time is 8+ hours even though Wifi on time is only 2+ hours. That doesn't seem to make sense, but what do I know.
I am running UnNamed 1.3.1.

I believe BBS is reporting scan time improperly. I've seen that in a few threads.

You're probably right, except now scan time doesn't even show.
I have also observed this on my phone.
I have a Samsung Galaxy IIs, using a Sony Ericsson MW600 BT handsfree as well as a Pioneer car Bluetooth handsfree system.
I have not measured anything yet, but I notice that when the Wi-Fi scanning is going on, I get significant disturbances on both of my Bluetooth hands-free sets. Listening to music is without a hitch, but talking on the phone (Norwegian GSM - operator Telenor) is terrible.
i also noted this after installing the OTA update to 2.3.6 today. I just rooted mine yesterday after reading 54+ pages to make sure i understood everything. i had a cappy and loved installing new roms but have not taken the plunge yet on the sgs ii. I haven't noticed a huge difference in battery yet, but it has only been a couple of hours since the update.
What ROM are you running? You can edit the build.prop to change how often it looks for networks. It is the line "wifi.supplicant_scan_interval=xx". I set mine to 180 which is 3 minutes, some ROM's set it really low. Also the scan rate is bumped up significantly when you're in the settings menu like Entrophy said.
Hi,
I had the same problem where my WIFI was fluctuating.... I dont know if this is the problem/ solution but this is what happened...
My SGS 2 is already rooted and unlocked. I had flashed the Entrophy DD 12/23 first then I had flashed Unnamed Custom ROM. After rebooting the phone, I saw the Wifi was not stable. So I again did a "Wipe Factory Data Reset" and "Wipe Cache Partition" and then installed the Unnamed Custom ROM from the SD Card. My Wifi is pretty stable now.
I am not sure if you guys had this issue when flashing a ROM but this seemed to fix it.

I have written about this wifi-battery drain a while back here in XDA.
When I used to have my Nokia symbian cell phone I used to flash custom roms
and there were a lot of nice new features after flashing.
A couple of the really nice battery saving mods were:
#1: added option to change the amount of wifi milliwatt output from 18 milliwatts (default) to 3 milliwatts
which is more than enough if the phone is no more than 20-25 feet from the wireless router.
(the mod gave the option of 3mw,6mw,12mw & 18mw)
Saves a lot of battery life.
Don't know why none of the DEVS have addressed this issue yet.
#2: added a mod so once the wifi establishes a connection it no longer scans
at all unless the connection is disconnected or lost.
So in other words, the phone only scans for wifi until it connects.
Right now I am connected to wifi with my phone and yet in settings it displays "scanning"
non-stop-constantly even though in wifi settings it displays "connected".
Why should the phone be scanning for wifi if it's already connected? (I have no idea).
Don't know why none of the DEVS have addressed this issue yet either.
Both of these mods really made a noticable difference in battery life
for for me since I do use the wifi feature in my phone a lot.
Hopefully one of the DEVS can look into these issues soon.
Now someone mentioned wifi constant scan, I noticed mine is doing the same thing. I leave the wifi setting screen on, it re-scans every 3 seconds!

Power control - Not likely, unless there is some documented power control already in the driver it's not going to happen. We're in a bad enough state as it is trying to make the chip not fire interrupts at 1 Hz on the Infuse.
Broadcom is one of the least open source friendly chipset manufacturers on the planet - their drivers have NO comments or documentation whatsoever, and datasheets are not available.
The rescan stuff is probably only addressable on Cyanogenmod, messing with it would require source code for the userland wifi management stuff.

As stated earlier in this thread - this is by design. It is assumed that if you're in the settings screen you want to change networks and have an up-to-date list.
I also am having this problem. I am running the rooted UKK6 from entropy512. After turning on my wifi, my battery drained from 90% to 70% in 5 hours with no use. My android OS is running at 80-90%. I don't have any extra apps except for 3g watchdog and CPUSpy and BBS. I do have Go launcher and GoSMS installed. As soon as I turn wifi off, i can see my battery level off under settings. I have searched for the last 2 days for a "fix". no luck.

Try doing a clean flash using "wipe data/factory reset" in CWM
recovery and then see if the phone has normal battery drainage.
(which it will if you flash the UnNamed v2.2.1 custom rom)
Then install one app at a time so you can find out exactly which
app is the culprit that causes your excessive battery drain.
This is the best way to trouble shoot battery drainage issues.
You will see that your battery drainage issue is not caused by
the custom rom, but it is caused by a few apps which are just
not very battery friendly.
The UnNamed v2.2.1 rom is the best custom rom currently
available for our i777 phones and it has outstanding battery life.
Good Luck!

This has nothing to do with this thread - This thread is talking about wifi scanning.
Drain problems - read my known battery drainers thread. A lot of people are having problems, there is no fix, and there won't be until all the people complaining start actually collecting some data.
Hello, everybody. Newb here (only have had the HTC Evo View 4G for a couple of days now). I have a question about the battery and screen. Is it regular for the screen to use up about ~60 percent of the battery? (According the usage stats). I find that the screen is bright, even on the lowest setting.
Also, I have a question about the battery. It seems to be draining a little quick (I am using lowest brightness and WiFi only). Could some people share how long their battery usually lasts for regular usage? I don't think it's a hardware issue. Like I've said, I've only had it for 2 days, so I don't know if I still need to wait a little.
Thanks!
The screen is one of the biggest battery drainers (if not the biggest) on tablets. So if you are using the tablet a lot, and the screen is on for long periods of time, then 60% seems normal. I don't have my Flyer with me right now to check what my % for screen is.
Battery drain is going to depend a bunch on how much you are using your View, and for what. With moderate usage, I can get around 2 days on a charge. I'd say that is about average for me. But if you are downloading big files and gaming, and/or have the screen on a lot, it can be significantly less.

Okay, that makes sense. The battery life seems to be getting better. One more question. I want WiFi to turn off after a certain amount of time once the screen timeouts. Is there any way to do this in the settings or with an app? The settings (official 3.2) has a WiFi timeout policy that gives three options:
Switch from WiFi to mobile data when screen is off
Never switch WiFi off
Never switch WiFi off when plugged in
I live in Canada and don't have a plan. Would using the first option drain more battery because it is looking for a connection? Or should I use the third option?
Thanks again.
Hmm, not sure. I have the WiFi only version of the Flyer, and on mine the first choice is just "When screen turns off". The first choice on your View is weird. Mobile data always uses more power than WiFi, if both are available. I don't see why you would ever want that.
BTW, I'm at home and have access to my Flyer now. Battery usage for screen is 52% for me. So I'd say 60% you mentioned is pretty normal.
You should also take into account, unless you've taken steps to turn it off/remove it, Cell standby might also be causing your battery life to take a hit. Since the View is set up to also be able to receive text messages, out of the box it's constantly trying to connect to Sprint's cellular network, even if you have mobile data turned off. This thread discusses ways to deal with it. Cell standby used to be one of the biggest users of my battery. Now, it's no longer a problem and I've seen a major increase in battery life.
As for the WiFi issue, the first choice in the settings actually says "When screen turns off (uses more mobile data)." That doesn't mean that it automatically switches mobile data on if you've turned it off in the settings by selecting that option. It's worded that way because the View is designed to be used on Sprint's network, so under normal circumstances it is assumed that if you turn WiFi off, you'll have a data plan and automatically connect to the mobile data network. If you don't have an account with mobile data from Sprint, and you've turned off mobile data in the settings, it won't be an issue because you have nothing to connect to.

That makes much more sense.
Okay, thanks everybody. I really appreciate it. With heavy usage (basically using it all the time) I'd get about 6 hours and 10 minutes. Is that normal for everybody else?
Also, I have a couple of more questions, if you guys don't mind.
First of all, could rooting my device boost my battery life? Would it give me more access to settings like screen brightness?
And, do apps running in the background use battery life or are they 'frozen' until active? This sort of leads me into my next question. Is having 400-500MB of RAM always being used normal? Is the OS using all of it?
And I notice that when I put my tablet in airplane mode (to kill the 4G radio) I lose access to Bluetooth. Is this normal and will turning off airplane mode for a minute be a battery drain?
Thanks again, guys.

Answers:
Rooting won't necessarily boost battery life, but does give you ways to access more system items if you want using apps that take advantage of root.
Android attempts to keep non-rumming apps in memory so that it can load them faster in the future (Ram is much faster than SD memory). 80% Ram full is typical.
Airplane mode turns off all radios, BT, Wifi, GPS, 3g.
There are apps in the market that can turn various things on / off based on your environment / time / conditions

You don't need root access to adjust screen brightness. Settings -> Screen -> Brightness.

Airplane mode turns off all radios initially, but then you can turn almost all of them right back on (except for the cellular radios). I run mine in airplane mode all the time to keep the cellular radio completely inactive, but I still use WiFi, GPS, and Bluetooth when I need/want them, and they all work great. Are you running Gingerbread or Honeycomb? I do seem to remember some mentions of not being able to use Bluetooth in airplane mode on Gingerbread. It works perfectly fine on Honeycomb.
And you can turn off the 4G radio and all data service without turning on airplane mode (Settings -> Wireless & networks -> Mobile network). Doing this turns off all radios that receive data from the cellular network, but it doesn't turn all cellular functions off since the View is also set up to receive text messages. That's what airplane mode or any of these options address.
What I meant by adjusting the screen brightness was being able to control its range more than I can right now (I feel that even the lowest setting can be too much). But it seems that rooting/installing a custom ROM wouldn't do too much for the battery.
But my issue with airplane mode is that I can't turn on Bluetooth with it (Bluetooth is 'grayed out'). I am running official Honeycomb.

Did you try tapping on the box for Bluetooth in the settings even though it looks like you can't, and did you try using a widget to turn it on? I'm using stock OTA Honeycomb, and Bluetooth works perfectly fine for me while in airplane mode. I can turn it on in the settings (the box does look a little "grayed out," but you can still select it) or via a homescreen widget. If you can't turn it on with either of those, then it would seem that you've got some other type of problem. It works fine for me. I just tested it out again.

I just tried it. It seems to not be working for me, but it doesn't seem like a glitch but something built into the OS (I tried with a widget and it did a little 'no' animation). It's alright, I rarely use Bluetooth anyway.
Thanks for all of your help (plus everybody else, too)!

I'd venture to say it's not something built into the OS. If it is built into the OS, then there's a glitch that allows me to use it under the same circumstances, and glitches rarely enable functionality. They almost always cause a device to lose functionality like you're experiencing. I'd be curious to know if anyone else is having the same issue you're having.
Last time I have ran battery test on my Flyer I ran it for almost 11 days on one charge. Yeap, 11 days. I mostly used Flyer as a notepad, checked orders on website couple of times a day, read emails. One day I played a game for about 20 minutes. At the end I set up and tested Plex and Google Music. I stopped the test at 11% charge. Overall screen was on for a bit over 4 hours (40%). Wi-fi on for 16 hours (only 4% ??) according to stats. That's pretty much it. Tablet idle 43%. Fairly light usage, but I mostly was testing how much of useable time I can get out of it. 11 days is a pleasing result.
Hello there,
I have a concern with my honor 7 (PLKL01B380) which his battery empties at high speed.
My system never comes in deep sleep. I lose almost 10% overnight. Since I disabled the update on the lock screen magazine, I've gained a little bit of autonomy.
What I do not understand is that the wifi reports that it is still active as I always cut the night. For information about the wifi, the relationship between the following two screen shots is strange. I do not know where to look for a solution. I did the update to the B380, I turn off wifi and sync during the night but still nothing. I have two sim cards, I know it consumes more but is that why consumption is continuous all night?
Thank you for your ideas.

Have u tried backup, factory reset and restore?
Hello,
Off course, i thinking about full reset but I don't like this idea because I don't want to lose time on reinstall my apps, organize in groups, reinstall all accounts and passwords .. etc.
I've searched in all parameters and I think i've found the two parameters causing trouble
1. As I say in first message, magazine unlock auto-update, set it to disabled
2. In localisation parameter / advanced parameters / Localisation Data / Extended menu (below) / Search parameters / Wifi Search, set it disabled -> this one make my wifi always on
Now, it looks better, phone going in standby, and wifi not always marked as activated in the graphical view of battery.
I'll see next night if it go to deep sleep :good:
Thanks
Well in my opinion it's better to waste a lot of time re-setting-up your phone than having a huge battery drain, but try a night more, it could be the solution you're on to:fingers-crossed:
I had battery drain problem too. I solved it just by switching off viber contact sync in viber general settings. It kept my phone awake with screen off, and my battery life was horrible. Let me know if it helps.

Hi,
I'm having battery issues with OPX again, first it was a faulty battery, but now it looks like the there's something wrong with the settings. The device loses about a third of it's battery overnight, but when I look at the stats I can see that WiFi is always on and the device is always awake!
I have installed naptime as well and told it to ignore sensors (not that it matters as the device is not moving overnight) and to sleep even if connected to a charger etc. No matter what I try the device is always awake.
Is there a way to find out what is keeping it awake?
When I look at usage since last full charge there's nothing unusual there, just regular apps and single digit percentage numbers.
Thanks for your help!
System version?
I'm on Android Marshmallow, using Resurrection Remix ROM.
I'm not quite sure how to use the wakelock blocker, but I just installed Wakelock detector and it shows TripAdvisor as #1 on the list. I have it blocked in notifications, but I can't find anything related to TripAdvisor in wakelock blocker.
Is there any way to prevent apps from keeping the system awake, or should I just unintall TripAdvisor completely?
Not sure if I'm on the right track, but something is keeping the system awake and I need to find out what
OS3 with google back up turned off I get zero drain. Maybe 2-3℅ max over night. Also turned off automatic updates playstore. With just those two things off dont see drain anymore might just be lucky.
Well I think I'm back on normal drain. I uninstalled TripAdvisor, not using it except when I'm on holidays. I disabled the option to keep WiFi on even during sleep.
I used wakeblocker to block all weather/facebook entries, and I have two gmail accounts, one which is use a lot and one which I don't - so I blocked all wakelocks from syncing the account I don't use often.
Battery history confirms device is now correctly going to sleep and turning off WiFi. Automatic updates are still on.
I probably blocked too much, but I don't care anymore, I have 30% more battery every morning and that's good enough for me

Which ROM and recovery do you use?
Hi guys, this is not the thread where you'll find fancy kernel tweaks to improve battery. I'll share a few little things I personally follow that considerably improved battery life for me. You don't even need root
If you use any other battery saving placebo like greenify or wakelock blocker, then you're on your own. I don't recommend these
Follow each of these steps -
1. Turn OFF pocket detection, screensaver and ambient display.
(AD is upto your preference, doesn't drain battery much)
2. Set location to device only mode.
(DE mode uses GPS satellites and gives enough accuracy, high accuracy mode keeps bluetooth and wifi scanning on, draining battery)
3. Turn location permission off for google app.
(drains alot of battery)
If possible disable location for every app except maps and google play services.
(tracks your device when it's lost)
4. Go to location settings, scanning and check whether bluetooth and wifi scanning are off, if not, turn them off.
5. Go to battery, performance and turn off automatic optimization.
6. Most important step, reboot your phone after doing all this.
That's it guys, try this and report Suggestions are welcome
Good Tips.
Very nice

Before greenify, it was like 5% drain per 10 minutes even if I won't use phone

Just try that bud
actually the thing is that kernel is not proper for any ROMs for which there is a battery drain...
changing kernels will be battery saving because of CPU tweaks running always in the background even if the device's screen is off...
use greenify in magisk for more if you dont want to tweak with your kernel...
do this and tell if your battery drain is solved... also follow these steps above.. they are mandatory as well...
it doesnot work well for resurrection remix ROMs... i have tried... maybe fixed by change in kernel tweaks...
For some weird reason my device doesnt go deep sleep anymore. The battery graph use to to be flat but now therea a slight steep when i am asleep. I still do my usual habit of turn of wifi, turn off location, turn of sync, turn off scanning for bluetooth and wifi, turn off locatiom history. I am on stuart's los 14.1. this started to happen two days ago. You know the best app to troubleshoot?screen and lineageos system and android is on top of battery stats when checking after waking up overnight.i have no addon or other tweaks. Not even greenify because battery graph overnight is flat before.

Where I can see you're doing wrong is turning things on and off. The steps mentioned in thread do not break a single thing. Keep location as device only mode forever (no on off required).
Just follow those steps for atleast one cycle and report

Ill try. Ive been doing this for a long time since teammex releases builds. And since the first build of stuart got no problem up to the second build.by the way i am.only turning on location once in awhile if i need navigation. Only wifi and data connection is frequently turned off and on. The rest is off 90% of the time

I'm on the latest build of Stuart and I still have no problem, easily getting more than 9 hours sot without compromising anything
Battery drain issue
Any one having a battery drain problem ........Go to magisk( if not installed plz find the tread and do it)....Then download Enable Doze ..... Optimize Google play services and Google app and see if it is fixed......Worked for me
Very nice practical advice. However, greenify is not a fancy placebo. Together with Leandroid, and only following no.1 and 4 of your guide, battery almost doesnt drain at all on my snapdragon Xiaomi when idle. For my MTk xiaomis, I have to flash the drain fix in addition to get the same results as the snapdragon variants.
Anyway, good advise.
