There is a setting under wifi/advanced "Scanning always available", what is its use? I would have thought that programs like Maps, would use it to locate you if you had wifi and GPS off (location set to battery saving). But Maps doesn't do squat unless wifi (or GPS) is actually turned on. "ADM" also doesn't work unless wifi or GPS are actually on (regardless of how scanning box is checked).
All that check box does for me is show wifi being on 100% in battery stats. I turn it off and battery stats bar goes off. But doesn't seem to effect battery either way. So that box makes no sense to me unless it's a bug not working in 4.4 or 4.4.1. Is there any use for it?
Its use, I don't know but it means if the setting is active, wifi is never truly off. Scanning can still happen.

OK, this location stuff is driving me nuts. I have Purity 4.4.1 on both my N7 and N5, no custom kernels. If I open Maps on my N5 with wifi off, it will zoom right in on my location with a blue dot. On my N7, just sits there waiting for location even with wifi on. I notice the wifi/advanced settings are a bit different on each (the n7 missing the frequency band setting), can anyone else confirm this?

Hi, I'm having a serious issue here. I unplugged my Transformer from my charger about about 11am today. I have used it, according to the screen on time in the settings, for 34 minutes. (it's now about twelve hours later.) However, the battery life is at 64%. I just don't understand this. My wi-fi is set to disconnect when screen turns off, and brightness is at about 55-60%. But look at this.

Does anybody have a clue what could be going on? If you need more information about what state it is in, I'll be glad to provide more details. It seems like this started after I updated to 3.2, but that could be unrelated.
After updating did you set up the wifi power saving again? There is a bug in android where this setting gets reset when the device is rebooted

Yeah, I double checked when I posted this and it was still on "when screen turns off".
Try using juice defender. And check your running services/applications/auto sync cuz i see there alot of wifi actifity and your device is awaken even though the screen is off.
You could try using an app called Sysem Panel by NextApp.
You will need the paid version so that you can turn on the Monitoring option in the settings - this allows you to monitor the CPU usage over 2h/8h/1d/3d.
You can also monitor Top App usage of CPU which is fantastic for identifying the culprit.
Hi there,
Over the past week or so I have noticed that my battery is going down a LOT faster than usual...
The culprit is "gpsd" that is using upwards of 30% of my battery every charge...
I have looked through everything that uses the gps and it's all either off or not using it.
How do I find out who / what is keeping gpsd going and make it play nice, or die?

Hopes help.

Definition - gpsd*is a daemon that receives data from a GPS receiver, and provides the data back to multiple applications such as Kismet or GPS navigation software. It thus provides a unified interface to receivers of different types, and allows concurrent access by multiple applications.
Workarounds - Look for every GPS associated application on your device. Make sure to switch off GPS.
Go to Settings, then to Application Manager or Apps. And find the GPS associated apps, open them and force stop them. Sometimes they auto run and can cause battery drains.
Tell me how this goes for you.

All apps that need location services disabled / uninstalled and it's still there...
Okay...
Just wiped and re-flashed rom... no apps installed aside from BetterBatteryStats and GPSD is still there...
Maybe time to find something other than Omega
Hi, I need help on this. It has been days since my battery has gone haywire and I don't know what happened. I just saw that my WIFI isn't turning off even though i toggled itoff in settings/quick settings. I thought maybe a simple reboot may fix it but no. I came from CO12 to Exodus to Bliss but all have the same problems. Wifi isn't turning off! All my settings are stock. Kernels are stock also. I'm getting an average battery life of 3 1/2 hrs SOT which is awful for my usage. Also AndroidSystem and OS is killing my battery but I disabled Google PlayServices which should help. My only concern is the Wifi not turning off. Pls help thanks

Hi.
I use this app wich does only cut on and off the network: https://play.google.com/store/apps/details?id=com.a0soft.gphone.aDataOnOff&hl=en
(you can also apply a screen filter to help stop battery drain)
But I doubt its your only problem... I tested with and without the app, and the difference is almost not visible. Also, my wifi (when app off) is in third place on battery usage, and I have at least a good 5-6 SOT..

Some people say that it is a common bug in Android 5.0. Can anyone confirm?

The known bug with wifi is not battery drain but the difficulty to connect, to link the network.
Hello All,
On both my wife's and my Tmobile S7s running 6.01 on the November security patch, the location services are terrible. The phone keeps thinking I am at my house when I am 20 miles away at work. My wife has the same problem. If I toggle location services off then on, it instantly updates to the correct location. Eventually if defaults back to my house. This wouldn't be such a huge deal if I didn't have a SmartThings home automation system. SmartThings keeps unlocking my front door, turning on lights, and putting the heat back on because according to the phone I am at my house and the automation kicks in. Here is what I have done to try to fix the location issue:
- Location on with method = GPS, Wi-Fi, and mobile networks.
- Improved accuracy on with Wi-Fi scanning and Bluetooth Scanning enabled.
- Under Optimize Battery usage, I have unoptimized Location Services (meaning it should always be running).
Does anyone else have this problem with their S7s? If it were jsut mine, I would chalk it up to a faulty device, but it is happening to my wifes as well. Any other tricks to make this stop happening?
Check your apps to make sure the location permission hasn't been unchecked. Exactly which app could be missing that is hard to say. A factory reset might be your friend for this kind of situation.

In many cases when I want to transfer files wirelessly via apps like SSHDroid (SFTP), other FTP servers or KSWEB (http) or Airdroid, a few minutes after the screen turns off, I cannot transfer files anymore as the connection is down. When I turn on the screen, the connection resumes..
In all these server apps I have enabled Wifi alive (i.e. keep wifi on when screen off), but it presumably it does not work very well.
It appears that the wifi always turns off when the screen is off, regardless of settings.
Is there an app which keeps the wifi alive when the screen is off ? I tried tTorrent running 'dummy' just hoping to keep wifi alive when using one of these file transfer apps, but that does not always work either.
i assume you have the wifi setting to remain on even when in sleep mode?

Of course and I have disabled to kill 'battery consuming' apps, see screenshot of 'Settings => Battery => [cogwheel top right]'.
But the screen is a worst battery hog as using file transfer over wifi requires the screen on.

In WiFi settings, tap on the configure cog wheel icon and change it from there. No need for another app.
