My wifi keeps turning on by itself.
Does anyone else have this issue? I am on the stock rooted ROM. I wonder if I installed something that does this. It's driving me crazy!!!
Arrrgghh.

You rang? lol.
Yes, I did at first when on stock. There's a setting, it is escaping me exactly where it is - but I believe it's in the 'advanced' wifi settings. Let me see if I can find the thread real quick.
This is a "feature" - basically the concept is, the phone tells you when you are near AP's to save $$$ on your cell data plan. Stupid.
Edit - there's also battery saving apps that could be doing this... just FYI, reading other forums they seem to indicate that rogue apps could be doing this - one user in particular mentioned some app called Snapdragon BatteryGuru...

I wonder if "Keep wifi on during sleep" was causing the issue.
Also, I do have that snapdragon app...but it hasn't gone through the 3 days of "learning" to actually be functional. If it doesn't stop happening from changing the setting on Keep wifi on during sleep to NEVER...then I for sure will uninstall the snapdragon app and see if that helps. The snapdragon app seems to only do what Greenify is already doing anyway. Hibernate apps.
Thanks for replying man! You are a great dev.

I'm just learning, but getting better at it for sure .
As for the issue at hand, I don't think that keep wifi on setting is the one I am thinking of...
Unfortunately I don't have a device to look at right now to tell you the exact setting, and I am having trouble finding the thread where this was discussed (I thought there was one at least)...
However, did you check the settings on that Snapdragon app? Make sure there's nothing configured there to enable wifi. Also, I'm not real familiar with all these battery saving apps - I would use caution, they might be like antivirus software on Windows - don't run more than one at a time, or else they will just butt heads.
Hi everyone,
These days the battery consumption of "Android OS" process has been quite high. Last days it has been around 30-40%, but today, it reaches the awesome figures of 70%.
I have francokernel-r32 (last one) which everyone reports it's a battery friendly kernel. Obviously I notice no difference between francokernel and stock because of the Android OS battery drain. Also I have the CM11s-R44 stock.
Other little details: I use Greenify, cleanmaster and Amplify to save battery and system resources. Localization is fully turned off (I don't need it) and using 2G and WiFi networks (I use 3G just for few minutes/seconds to download or surf the web).
The xposed modules I have installed: amplify, bootmanager, complete action plus, greenify, whatsapp quiet hours and youtube adaway. I think none of these can be suspicious of battery drain.
Any suggest? I have no idea on facing this problem...
Thanks so much :good:
Edit: pictures are in spanish, but I think it's easily understandable (just the figures of Android OS process say everything).
Firstly, you say 'also I have CM11S-r44 stock', but you're not stock if you have Franco installed. Anyway, it could be Google Play Services that's causing the problems, have you tried this?

have you read the thread on r32 its been giving people some issues. May I suggest r31 and as previously mentioned are you running Google Now. I mean the the drain you see could be warranted. Also what the Keep Awake showing you? How bad is that

I'm going to piggy back off this thread. Android OS and Android System are killing my battery as well. I've turned off the Google Location Services keep awake and wake up (etc...as per Timmaa's thread), and I'm still getting a very large keep awake from Android System. Please see the attached screenshot.
Nothing else has been edited. I'm on 44R stock rooted.

I'm not really sure actually. I'm connected to WIFI around 80% of a given day so my guess would be yes.
Do you know of something that could be causing the drain, or is that just what happens when you're connected to WIFI?

I have this issue from time to time when connected to my home Wifi. You could try by turning off Wifi for some time.
Rebooting the Wifi AP or changeing channel helps for me in that case.
Is it a hidden network?
Nope it'd a public password protected network.
OK, so I know M7 isn't the latest CM build, but it's the latest one without issues with GPS, so that's what I'm on since I use GPS a lot.
So last week I replaced my home router. This of course means reconfiguring all the wifi devices around the house, including my wifi thermostat. The unique thing about the thermostat is that to configure it, you connect a laptop/phone/tablet to the thermostat's ad-hoc wifi network, tell it which infrastructure ssid to connect to, verify a pin from the thermostat's screen (so nobody can hijack your t-stat from outside the house), and that's it.
thing is, when you use Cyanogenmod (at least on the relay) to connect to an adhoc network, it breaks wifi. what happens is you can't connect to any other wifi networks, and can't even scan to see available networks till you reboot. sometimes it doesn't work even after a reboot. strangely, the tethering/hotspot still works fine. you just can't connect the phone to a hotspot whether it's at home or work or anywhere.
i'd been having other issues and general slowness with the phone, so i decided to backup a few apps with TiBu and do a factory reset. that worked... till i tried connecting to the thermostat again, and it broke wifi completely this time.
solution? go to /data/misc/wifi/ and rename wpa_supplicant.conf to wpa_supplicant.conf.old (or whatever, as long as it's a different name) and reboot. the system will automatically create a new conf file. boom - wifi fixed.
obviously this requires root, but that's not an issue in CM. I doubt it matters, but i used ES file explorer since it's got a good root filesystem browser and mounting / or system as RW is a simple matter of a checkbox in the settings.
when i compared the newly created wpa_supplicant.conf with the one i'd renamed (.old) the only real difference i could see was the saved networks at the bottom. so you might be able to get away with simply deleting the offending network={ blah blah } section instead of completely renaming the conf file. the advantage here would be if you have a bunch of saved networks that you don't want to get rid of, it will keep those saved networks. the conf file is a plaintext file so it's easy enough to understand what you're looking at, and modify appropriately.
MODS: I apologize if this is in the wrong forum. I figured since it probably only applies to CM, I should post it in the dev forum rather than the general one. If it needs to be moved, I don't be offended.

As does FatToad. However, I do know that the privacy bit in the GPS can be flipped with the drivers we're using in FT. There's an old thread with a post from nard about how to fix that.

Do you understand more about this "privacy bit", what call in the API flips it, or can give me any other pointers about it? The poster previous to you indicates that GPS works with M7. I thought I had it working with M8, but can't really guarantee that, any more. The post from nard was quite an onerous process, including what looked like reflashing the baseband.
It seems to me that if we really understood this problem, the fix would be quite simple, and could be done by a root-access app. I've done more digging, and see that it seems to be common to many models of Samsung Galaxy phones, and some of the fixes involve doing potentially horrible things to the NVRAM. (like clearing it completely - what could possibly go wrong?)
It seems that the GPS is done in the baseband processor, along with the other radio stuff, but so far I haven't been able to find it. The transceiver chip is just a transceiver, no baseband processor. It looks like the baseband processor might be on the Snapdragon main processor chip, though they don't enumerate it well. In addition they mention a "gpsOne engine" without describing exactly what it is.
I'm still relatively ignorant about Android, a year after getting one. (not enough time) I'm better versed on hardware, but this problem seems to be in the cracks between.
Come to think of it, a simple question... Is there documentation on the communications between Android and the baseband processor?

I just took my wife's phone outside and tested it. GPS works on M8 from last summer, as does wifi. AFAIK the only thing that doesn't work on M8 is the video camera. (Stills on the camera work.)
This was an older phone than mine, purchased after mine. With mine I didn't need the radio or bootloader updates, my wife's did. I bought the phone for her, used it briefly with my PureTalkUSA SIM card to make sure it was really unlocked. Then I put CM11 on it.

no idea how old mine actually is; i bought it "like new" from a tmobile reseller here in town and i actually use tmobile for service.
right now i'm on fattoad and once i stepped down my paranoia (i turned on privacy guard for everything including all system apps. hint: don't do that ) it seems good so far. nova launcher has an issue with flickering or disappearing icons, and everything is huge (i need to adjust the dpi) but so far no issues with gps or wifi (though i havent needed to connect to an adhoc network yet).
Do be careful with Privacy Guard. I didn't mention, but although Privacy Guard out of the box tends to make it so that most system apps are unable to be tuned, TeamApexQ likes the option of being able to tune everything in that regard, so we removed the safeguard. (For example, when PG was first ported to CM12, you could tune the settings of the 'Settings' app. Then at our next internal testing build, it was suddenly coming up empty, because CM made a change to exclude tuning for it. We restored full capability because we liked it. But that does mean you can more easily 'shoot yourself in the foot'.

I've recently begun to wonder if Privacy Guard might be partially responsible for reduced battery life. I'm under the impression that it lies to apps, providing false information when they have insufficient authority for the real information. Some of those permissions in Privacy Guard are to turn radios on and off. If an app thinks it's turned a radio on, and is trying to communicate based on faked (Really, it's going to look like a failure, at this point.) returns, it may spend more time continuing to try instead of just staying asleep. My battery life comes an goes, but I've noticed that on a "bad day" there are quite a few wakeups in the middle of nowhen, when the phone was sitting there in airplane mode with all radios off.
Of course I may be all wet on this - radio control may be one area where it can say, "You're in Airplane Mode, no program can turn the radio on."
good theory, and like you said, it depends on the app and how pg implements each block.
personally i'm having great battery life in L. i have a 5000mah battery, but usually by this point in the day i'm at about 60%. right now i'm still at 83%. i like how it projects your estimated remaining battery time. first time i looked at the battery chart, i lol'd - it was projecting 4.5 days before it died. i can probably get 2 no sweat even with regular usage, but i'd have to turn off sync and really cut back to make it 4 days.
I've had very good results with some simple rules with Privacy Guard. Generally the only thing I've turned off is the ability for Google Play Services and the Google App (Google Now) to wake up my device and to keep it awake. With those turned off, my battery life has gotten to be pretty damned nice... Though it makes Google Play Services FC once maybe every 24 hours. It restarts just fine, no harm no foul.
My battery life seems to be "bimodal". It either barely makes it 24 hours - basically needs recharging every night, or it lasts on the order of three or four days on a charge.
It seems to be somehow wifi-related, if I were guessing, and in an odd way. If wifi is largely off, but occasionally on, the battery life seems shorter. After wifi has been left off for "a while" (quantity not yet determined) it seems to go into long-battery-life mode. If I keep wifi largely on, and occasionally off (basically between known/trusted wifi places) the battery life comes out somewhere in between, consistent with wifi itself taking some power.
It's been really tough to detect any sort of pattern, but this is the best I've been able to come up with so far. I haven't done rigorous testing, or at least attempts at rigor so far have yielded inconsistent results. I've looked at what the Settings->Battery has available for power diagnostics, and one thing I noted was a lot of spurious wakeups when all radios were turned off. That's what led me to tentatively finger Privacy Guard.
I just saw the setting to show "built-in" apps on PG. I see two different entries for google.services and google.services.framework. The former has scads of wakeups - thanks for the tip. The latter has many, but a much smaller number. Did you block wakeups for both? I presume "built-in" are also "system" that others have said shouldn't be bulk-denied in PG. Are there guidelines anywhere about which are OK, which are useful, etc? (Like this case, and perhaps battery life.)

It's difficult to give tips for this, because everyones' usage is different. Get 'WakeLock Detector' and keep an eye on that when your power drain seems more intense. Disable things that make sense to disable based on that.
I know this isn't really the topic, but just because you get a new router doesn't mean you have to reconfigure everything. Why couldn't you just configure the new router with the SSID and password from the old one?

believe me, i tried that. it's stupidly tedious to enter a long keyphrase via the remote control on our tivos and only slightly less tedious on the roku (its remote is much more responsive). laptops and phones aren't as bad since they have keyboards. apparently the devices are smart enough to notice a different MAC behind the BSSID. which if you think about it, is actually a GOOD thing in terms of security, since it makes spoofing a little more difficult. granted, you'd also have to know the wpa key to successfully spoof, but it's a simple check to implement for security's sake, and i'm glad they did.
by the way, do you like fjords?

"Wakelock Detector" has certainly been enlightening. "Google Fit", which makes sense, once you think about it. But the other aspect that was even more important, I just happened to see when one of the other forums popped up on some sort of search result or other.
You have to boot your Android device on battery. If the kernel starts up on charger, it never gets into the deepest power-saving states. When I first started using Wakelock Detector, my phone showed up as being awake something like 97% of the time. Google Fit was the biggest user, but not that big. After seeing that advice I've been careful to boot on battery, and now most of the time is spent asleep. Google Fit still uses wakes as much, but when it's not, the phone is really sleeping. My normal battery life has moved out to two or three days, sometimes into a fourth. As long as I consider Google Fit worth having around, this battery life is good enough for me - there is always a decent window to recharge.

So much for that theory. A day or two back, after good battery life since this post, I noticed it draining faster. Today I looked, and sure enough, it's not going into deep sleep. I tried rebooting with all four states of wifi and cell service, and nothing has gotten deep sleep back. I think I'm going to try charging tonight, booting while charging, then rebooting after disconnecting. It would be good to have an exact and repeatable set of circumstances that cause both good and bad battery life.
Since updating to the OTA Lollipop the "T-Mobile My Account" app is killing my battery. I'm getting fast battery drain with that app being the highest consumer of power. I've been hesitant to root this phone - but that may be the only way to solve this. Are others seeing this? What options are there besides rooting and freezing/uninstalling?
If you know how to use adb, you can remove/block a lot of the bloatware apps including t-mobile my account app from running, without having to root your phone. i used this method while on kitkat and when i upgraded to lollipop, the apps i blocked stayed blocked. good luck!

I use it to stop the service T-Mobile My Account, is really easy to use and one you check the box in the program, go to APPS you see that the app is still there but force stop it, and then reboot the phone, the app wont start again. Im trying to see if my phone drain the battery again whitout it, kk give about 29 hours of use, hard use skype and phone calls and whatsapp and wifi all the time, i want to see how much juice i get now with lollipop... hope this is useful for you.
Hi folks,
I scoured through all the battery related discussions and wasn't able to find an issue similar to mine, so I hope it's okay to post a new thread on this topic. I have an AT&T (Snapdragon) Galaxy S7 with stock software and about a month and a half ago I started experiencing horrible battery life. I have been desperately trying to figure out what the issue is. At first I thought it was AT&T WiFi calling because it was forcing my WiFi and data connections to toggle back and forth and disabling that did help. However my battery life was still poor and I could never get more than about 10.5 hours of moderate use (see pictures below). Also the phone gets hot randomly (Above 95 Fahrenheit) even when doing minor tasks like browsing through Chrome. Since then I have made the following changes with no noticeable improvement:
Disabled advanced LTE services
Disabled Always on Display
Disabled WiFi and Bluetooth location scanning
Disabled nearby device scanning
Wiped cache multiple times
Temporarily disabled Bluetooth and WiFi to monitor the difference
Used Greenify Aggressive Dose
Disabled all diagnostic reporting
Uninstalled Oculus when that battery issue came up
Side note: I disabled a bunch of bloatware right when I got the phone, not through Package Disabler but through the standard Android disable method
I kept digging and found that my phone doesn't enter dose unless I use Greenify, and even then I don't notice a difference. I then decided to do a hard reset but no luck. Afterwards I used Safe Mode to see if any 3rd party apps were misbehaving, but again the drain was consistent both while idle and while using the phone. Today I installed Wakelock Detector Lite and found that PowerManagerService is keeping my phone from dosing, but from what I've read online it seems that info doesn't really point to a specific app, and it's hard to identify unless I root the phone which I don't want to do.
I am going crazy trying to figure out if this is a software/settings issue or if I should just replace the phone through AT&T and risk getting a defective refurb. Any help would be much appreciated.

Many people have similar problems. One reason was the buggy oculus app (you might wanna disable that when it came pre installed, depending on your CSC).
However the main reason behind the high "android-system" usage is still unclear. Some people experience it, some dont. Some people have better battery results with the firmware from March.
Personally, I believe that it is firmware related. I tried the N7 rom port and did not have a problem at all.
You might wanna wait for the October update that will hit soon and see if this fixes anything.
I notice you have 'media server' showing in your battery stats. My wife had that showing too and also had terrible battery life. Her fix was disabling the auto streaming in her Facebook app which plays videos while you scroll through posts. Now she has great battery life!
I have the Facebook app disabled on my phone altogether. I've also used safe mode where 3rd party apps are disabled but the battery still drains at around 5% an hour while idle.

Nothing has helped so far so I decided to uninstall my apps in batches until battery life improves. I'll then slowly reinstall them one by one until I find the culprit. I'll report back with my findings. Thanks for all the suggestions.
