Having just returned to the latest stock firmware after a couple of weeks testing CM12.1, I am finding that even if I turn "Keep scanning on" off in advanced WiFi settings menu, it comes back on by itself. Also, when I check my battery stats, it nearly always seems to show a solid bar for WiFi regardless of whether my WiFi was turned on or not, regardless of whether always scanning is on or off, regardless of whether location is on or off... it seems to have no effect whatever the settings are.
I am also unable to use the Power Saver function. If I try to open it, I get the "Unfortunately power saver has stopped" message. I read that disabling the stock clock or calendar apps causes this problem, so I deliberately didn't do so. Are there any other stock apps that will stop power saver from working if disabled? I guess I may have to enable everything again and then disable one by one checking power saver each time to find the culprit, but that is a huge pain in the behind, so thought I'd ask you guys on xda first

This problem is with the screen and phone not going to sleep mode after an event that brings it out of sleep.
After i lock the screen manually by pressing the button on the top, the phone would wake up briefly due to an event like a calendar reminder, text, phone etc.
So after certain duration of inactivity, it should go back into the sleep mode automatically. Right, it used to, but not anymore. It just stopped. I have checked the Advanced settings under the Battery option but no good.
Although after say 30 seconds (as per my setting) the screen fades to low light to conserve battery, but remains active.
As a result i have inadvertently pocket dialed quite a many and it's beginning to be a privacy concern and a pain in the butt for me and others. Not to mention the charges from the international number my phone self-dialed.
I'm using a TP-2 Rhodium OS 6.1.
As if the battery didn't suck enough, I needed this !!!
Any tips would be appreciated.
If the phone "used to" go to sleep but doesn't anymore, it sounds like a recently installed program or process is running in the background forcing it to stay on.
Does the phone refuse to go to sleep only after being woken up by an event?
...or does it not go to sleep on its own at all anymore?
Isn't pressing that button on the top just closing the screen?, unless you set it as the lock as well
I should have mentioned - the phone will go back to sleep mode if I manually operate the button on the top. Just that it won't go to sleep on its own anymore.
You may be right user602, about the recently installed apps, but is there any way to narrow down on the culprit instead of uninstalling all of them?

Go back and check the power settings again; make sure they are set to have the screen turn off. Change the settings to some other value and see if that helps. Maybe something just messed around with your registry entries.
If not, you will need to uninstall those programs, in reverse order, until the device works.
I'd start by changing the power settings as suggested by stevedebi above.
If that doesn't help, and you want to avoid uninstalling a bunch of stuff, you can look at what's running using Task Manager:
-Begin by stopping running programs one at a time, and seeing if the device will sleep.
-If that doesn't help, stop processes one at a time, and again see if the device will sleep (watch out for critical system processes, though).
...or if you're lucky, you may find something in the \windows\startup folder, such as a program you were not aware is starting on boot.
Of course, this all ends with uninstalling programs one at a time if none of the above suggestions work.

I can swear i tried this before and it didn't work. Changed it one last time before doing anything else,... and voila !!!
Thanks 602 & stevedebi
That was easy!
I'm glad the simplest solution worked for you.
...That's usually not my luck!

Hi,
I just discovered something strange: I use FolderSync to sync Music to my GN. I configured it to only sync when WLAN is available. When I sync and switch the screen of, then the Sync stops immediately and resumes when I switch the Screen back on. Is WLAN switched off when the screen is switched off? Did I miss some settings to configure that?
Thanks
May be related with some auto task killer or process killer like juice defender
Yes you missed some wifi settings. You can set there whether you want to turn off wifi with the screen, keep it always on or keep it always on while charging.
You can find it in:
Settings - wifi - ... - advanced
Thanks martan1981, but this is "always on" on my GN. So thats not the reason
Do you have any battery-saving apps like JuiceDefender or GreenPower installed? That could cause your data/wifi to turn off with the screen.
Or there could perhaps be a power-saving function built in to your ROM? I know AOKP has a Power Saver mode that could be enabled to turn data off with the screen.
wifi sleep policy should be set to never. But some people have a bug where this setting does not stick for some reason. You prob have this bug too.
I also have this problem how to fix it ?
No root stock 4.0.2
Sometimes when my phone comes out of sleep mode, the wi-fi doesn't pick up at all, so I have to disable and then re-enable it.
I tried reinstalling the radio button and still nothing.
I have Battery Defender and GSAM Battery installed and thought maybe it had something to do with the settings there to save power, but there doesn't seem to be anything there that would affect the wi-fi.
Anyone with any thoughts?
Thank you

Battery defender might be putting your WiFi to sleep to save battery when your device goes to sleep.
Also check to make sure WiFi isn't set to standby on default.
Go into settings select WiFi tap menu button press advanced and make sure keep WiFi on during sleep is set to always or a similar setting

I have a new verizon Note 4. It's been a great phone with very few problems until recently. I can't turn off the GPS. I'm not talking about GPS running in the background of applications. I'm talking about in the Location settings I can't turn off the GPS. I slide the switch to the off position and it jumps right back to on. There's nothing I can do. I've taken the battery out, force stopped all the applications that access my GPS, and cleared my cache in the safe boot settings. Does anyone know why this is? Under "Locating Method" I can't change it to anything but "GPS only". Power Saving is grayed out and High accuracy will allow me to select it, but when I go back into settings it is back to GPS only. This isn't a huge problem, but it's concerning me that I can't decide when I want to have the GPS network disabled or not to save my battery.

You may end up having to do a factory reset. You could try downloading a toggle app and use it to try to turn off GPS.
On android devices it was always possible to switch localisation services and GPS separately.
You could keep localisation services turned on (with wifi and phone) and turn off GPS to spare battery.
Now with android pie and new smasung settings it is all or nothing as there is onlys one setting :
I can turn on localisation and it turns on GPS
But if you turn it off, it disables everykind of localisation : GPS but also wiifi ...
Has anyone noticed this and is there a workaround ?
I'm not a fan of the always enabled GPS
I really do not like this at all. I have typically always kept GPS off as far back as Jellybean, favoring Locations battery saving mode, unless I needed navigation or something like that. GPS is power hungry and there's no reason to have to have it always enabled. I know Pie is supposed to help with battery usage and I honestly can't judge whether or not it really does yet as this is day two for me.
Pie is supposed to prevent apps from accessing sensors in the background but I've read that this doesn't apply to GPS so this whole thing is probably part of a marketing thing giving Google as well as app devs the ability to monetize ads based on specific location of us the users. Location is frequently wrong about where I am anyway, showing me a street over and even though I have WiFi and Bluetooth scanning enabled. As a result, my Safe Unlock no longer works when I'm home (only location I have enabled) which sucks. With Oreo I saw this somewhat often and only after I had been home for a while would the Safe Unlock work properly and I accepted this as a consequence of having Location in battery saving mode but now I'm not sure. I just no that with Pie, so far, Safe Unlock hasn't functioned once. My designated home WiFi that I'm on as I type should cause Safe Unlock to do it's thing but it's not. Maybe Location or Safe Unlock are broken. I have seen reports of both regarding Pie so I can't blame it in Samsung. I guess I'll have to try to figure out which of these features is broken.
I'm not sure if this is related to the Location issue but I also noticed that Samsung+ is not working for me. When I first tried to open it I got a notification that I need to have location enabled, I agreed (it was anyway), then I was shown a red screen with error or format codes that force closed faster than I could decipher it. This could be related or could have been broken in an update. Other than for ad purposes, and I don't recall seeing any other than Samsung ads in the Samsung app, I don't know why Samsung+ needs to access location services as it only works in the US and the network tells the app I'm in the US as well as the tower I'm accessing. I suppose it's another attempt to collect user info related to WiFi, Mac address and Bluetooth. I only got the "enable location" request the first couple of times I tried opening the app but the red error screen and FC both still occur. I tried to get a screenshot but I could only manage about half of the screen before it FC'd. I attached the partial pic. It's the bottom half of the screen. When it closes, the app window seems to slide up like when you close apps in the recents view. This brings up another complaint...Screenshot is slow to respond so events like this are next to impossible to capture. I'll have to get a camera out and try.

Yes I noticed this. I use 'Tasker' app as a workaround. I set Location Mode to High Accuracy when using Navigation apps, and set to Battery Saving after closing the Navigation app. You can also just create a widget on home screen to toggle Location Mode to High Accuracy or Battery Saving.
I confirmed this setting by using 'Power Toggles' app widget. When the GPS toggle in widget is highlighted, it means on High Accuracy mode, if not highlighted it's on Battery Saving mode.

I have yet to notice any adverse battery performance since I've been on pie and I've been on it since the start of the official betas. I was annoyed at first because I had always used battery save mode but really it's been a non issue for me.
