In advanced wifi settings, there is an option to "keep wifi on when screen is off."
Which is the more power efficient option, keep wifi on or off when the device goes to sleep?

It depends, if your LTE signal is bad then WiFi is better on so its not searching for LTE when it's sleeping. It's good if you won't be searching for signal and your phone isn't being used. If you are constantly using it them leave Wi-Fi on.

Makes sense I guess. I usually get around 2 bars in my home.

Last quick question. Is 15% of battery usage by "Android OS" considered normal? It's the 2nd biggest drainer on the list.

3g usually takes more battery than wifi. I personally experienced it.

Agree with you also. At least 2 charge per day.

its normal i think.. when a mobile network is on there are so many applications that auto run on your background and some of them are using mobile network connections and if you leave your mobile network activated it means all the time there are some applications that accessing the network which uses so much of the battery power, meanwhile the wifi connection only uses battery when its scanning(depending on the time interval that you set to scan when your not connected) but if your connected it also uses much power however its not that power consuming as the mobile network.
Recently I have been having something, I am not sure what drain lots of battery with leaving no trace that I can see for wakelocking... but it IS keeping my phone awake.
Also I don't even use maps and it eats up a ton of battery wth.
Set your wifi to turn off when your screen is off.
WiFi settings > menu button> advanced> keep wifi on > never
That should help some.
Also, what is your screen on time?

Screen on time is pretty low, switched it to keep wifi > only if plugged in.. so at night it saves data.

That should work too. The only other way to figure out what is taking all your battery is to scour Better battery stats for rogue wake locks and such. I un installed all my user apps and am reinstalling as I use them so that I don't have a ton of extra stuff running in the background eating all my battery.

Also for note: I am on LTE because I am at school.. some of the building have really bad connection/ 1 or 2 bars LTE.
If I knew how to turn off LTE I probably would...
Also why is maps so high I don't use it.

I find LTE chews up battery. To turn it off should be settings/more settings/ mobile networks/ network mode. And then choose the one under LTE. Saves lots of battery. Also might want to disabled GPS. I looks like it is on according to pics.

Idk if maps has been fixed their problem yet but the latest version of maps has a flaw that keeps it on. Go into the app into and in install the update and see if that helps.

Uninstall the update. The new version keeps phone awake. Uninstall it and uncheck the box in Google play to update maps.

My maps has been doing the same thing. Is horrid. Even disabled all latitude settings, gps etc. Still massive wake ups.
Is there a link to a previous non horrid maps app?

In your app drawer tap and hold maps then drag it down to info. There should be an option to Uninstall update.

That will drain battery quicker; WiFi is more energy efficient than lte.

Only fix is to downgrade. Or wait for Google to patch with an update.

Do you have latitude enabled? That might be the reason
Had the latest gmaps I just downgraded to factory and I will see how it goes.
Sent from my SAMSUNG-SGH-I747 using xda app-developers app
I uninstalled the gmaps updates and the resaults are good. I didn't thing the change would be this big haha. Google needs to fix the issue.
Edit: By the way is there a way to fix cell standby?
Just wondering if anyone knows why when I turn of data especially, my phone can go 24 hours in one charge but leaving data on all the time diminishes the battery life. Is it a modem thing? I always had battery issue but turning off data seems to help a check lot. Thanks in advanced.
Sent from my SGH-T999 using xda app-developers app
Do you often leave the coverage area? Because constantly searching for network when there is none will eat battery. Also If you have data on it will allow background apps to use the internet, which consumes power as well.
You probably are getting a much stronger signal when it isn't trying to stay connected to mobile data.
The weaker your signal the greater the battery drain. Often when you enable data you get a weaker sig.
Also make sure its not set to wcdma only.

I'm in pretty good coverage area.
Sent from my SGH-T999 using xda app-developers app
It is pretty normal for you to have more battery consumption with the data on than off. I had a myTouch 3G slide that could go for 3 days if I left the data off. Check to see if you have any apps that are being synchronized too often because that could be causing your phone to die quicker than normal.
With data off apps can't update(refresh) right? That should keep them from waking the system up.

Try having wifi on when possible if you dont want to disable data.

Still use it for an alarm.

If they are set to sync they will still try. You have to turn off sync. But if they can't get out they still don't transmit so still less battery use.

Yeah that will probably fix the issue. When I was on TW, under the battery tab, I noticed that my phone would wake often during the night. Now with the data off, it stays asleep longer. I think ill have to use something like juice defender that enables and disabled data automatically

Anyone having problems with WiFi turning itself on automatically? I don't think I have any apps that I didn't have before that would turn it on by themselves.
Go to settings, more, connections optimizer. Turn it off.

Didn't realize that Sprint added this to decrease their traffic by randomly turning it on and draining my battery!
If it's the same as other phones, they claim it conserves power. It doesn't have to search for a signal.

From my three days of experience with it, it seems like it searches for a WiFi signal not often enough so you'll leave your house and then WiFi will be on for a while before it realizes there is no WiFi and then be searching for WiFi that whole time you're gone, waking up to do so. Not sure if it also searches for an LTE signal or not too.
Why does this happen and is there any way to stop it?

Go to:
Settings/ more settings / mobile networks / CONNECTION OPTIMIZER
then uncheck the box and that will disable the Wifi auto-connection. Hope that helps. I have the same issue the day i got my phone. =)

YES! Thanks, Jeff! I am using Tasker to turn all data connections off at night, but when I plugged it into the USB, it turned WiFi on and I kept getting alerts throughout the night. I understand the principle, but that was annoying.

well, wifi uses a lot less battery than 3g and way less than 4g. the optimizer is a good idea, but just works terribly.
