I've heard arguments from both sides, but I've always been under the impression that the phone uses less battery while connected to wi-fi, and therefore the sleep policy should be set to "never".
Am I wrong on this?

If you're in an area with a wifi connection then yes, using it and setting it to never sleep conserves more battery. It uses less energy than the 3G radio

Be careful because I've had my device fail to go into deep sleep because of WiFi being on the entire time (not charging). Drained the battery a lot more quickly than 3G + deep sleep.
I always set mine to never sleep and never had any problems.

Is there any way to prevent this phone from going into deep sleep mode?
I use Groove IP and occasional, the phone will go into deep sleep mode and connection to Groove IP is lost. It only re-connect after I wake up the phone.
Thanks
Still having issues?

Yes, still have issue occasionally. Like once a day.
I use 4G instead of WiFi.

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.
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.

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.

lol! My slide was/is a beast! Dropped, kicked, slammed, scraped, you name it! Not a scratch on the glass! Cover looks like it was in an explosion!
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.
Deep battery forces your phone into deep sleep mode. In the free version there are different modes based on how often you want it to turn on data for a 1 minute period. I've only used it for a couple of days and results seem very good thus far. I am on Franco R15 and Dec 17 build of aokp roman

I downloaded this app at night. So the first part of the graph is daily use and the second part of the graph is night time. So far it seems to be working very well I am on the balanced profile of the application. Which is set to leave deep sleep every hour for one minute

I'm using juice defender.. It does so much more than deep sleep if it is set up right.

at least from my testing, DSB gave me worse battery than just stock... But, that may just be based on how i use my phone (I turn the screen on for ~10s at a time multiple times throughout the day for texts etc) Seemed to have more partial wakelocks than normal. I do suspect it has something to do with the wakelock issue the nexus has with the wireless radio
