Wifi off VS. Wifi on - Samsung Epic 4G Touch

okay so when I go to work I usually turn off my Wifi to save battery while I'm working since I keep my phone on. I don't touch it at all and I always leave the house with a full charge. The other night I accidentally left the Wifi on and when I left work I looked at my phone to realize my battery was a lot higher then when I turn it off. I don't connect to my works crappy Wifi either so I think it would be searching the whole time wasting battery... so what's better or is something wrong with my phone?

Wifi off when not in use is better for battery.

So wait you are saying that you saved battery by keeping wifi on but wifi never connected to any network all day?

Yes that's exactly what I'm saying! Which is why I'm so confused! I tried it multiple times too and every time my battery was a lot higher leaving it on not connected to any network...

Wifi and 3g toggling question.

Will it waste my battery more if I have 3g and wifi on at the same time? Even though only wifi shows up.
Sent from my PC36100 using XDA App
Wifi and 3g are never on at the same time. When you turn wifi on, it automatically disables 3g.
Okay, but does that mean it is better for me to leave both on just in case I leave the house and forget to turn off wifi. Or does that drain more battery?
Sent from my PC36100 using XDA App
Depends on what your wifi sleep policy setting it set to. If its set to never, then your wifi would never turn off.
But generally, yes, it uses less battery on wifi than 3g, so use that whenever possible.
What I'm trying to say is: if I have both toggles on does it use more battery? Even though wifi overrides.
Sent from my PC36100 using XDA App
If your WiFi is on but not connected to a network then yes it would drain more battery.

That makes sense. But I meant the opposite lol. Like if I have wifi and 3g on. Is 3g draining any battery? And sorry I suck at explaining.

No, 3G wouldn't be draining your battery because wifi turned it off.

Wimax

If I NEVER use 4G, can I freeze all of the WiMax stuff without causing any problems? I am trying to find ways to stop so much usage by Android system. Usually showing about 80-90 percent.

That is accurate. Like Windows all apps running on your phone go through Android system. It is the OS. In Froyo it was incorrectly pushed to the display percentage. If you have light usage and after about 12 hours your percentage should be between 60 to 70 percent. Freezing WiMax won't do anything since they only run if you turn on 4G.

Thanks Kenny,
Most times I am in the 80's, so when I saw things like WiMax line test, and mode change and Net test, i was wondering if those were things running, even though I never even bother with 4G. but i guess it makes sense that if I am not turning 4G on, ther services most likely are not causing any issues...i guess i will keep digging!

With CPU Spy how much deep sleep does your phone get? Reboot, put it down for 30 minutes. Open it and check CPUSpy. You should have most of that as deep sleep. Of course this is off charger. Charging keeps phone awake at 100 Mhz.

911 is fixed, before a new build is posted Decad3nce needs to be home(school/work) as this is a serious matter, so it'd be best for him to handle it because his name is on it, as you can understand. mkasick found out what the issue was and fixed it, the Fascinate has it as well, the fix is for CDMA phones....the Vibrant might actually be f*cked... UberPinguin, mkasick, and noobnl did it yesterday though but called 911 today through proper means and verified that it works. And pushed the fix upstream to official CM so that it can be included in.

Battery is dying extremely fast

On my gfs epic she's running aokp build 4 She has had the battery since the phone first came out.. She routinely leaves it on the charger every night.. everything is turned off except for wifi in the settings and gtalk has been signed out off and I have tried everything to conserve battery from rootdim which didn't do anything to build.prop tweaks in omairs thread.. The phone doesn't last at most five hours screen on with an hour and a half screen on.. Is this normal or is it time to buy a new battery

Maybe try odin to fc09 factory and see if it makes any difference. Best advice I can give you, is to leave a womans phone alone. Just trust me.

Change the processor to conservation, and tell her to turn off mobile data when not in use.
Sent from my SPH-D700 using XDA Premium App
It is probably time to get yourself the SGS2's 1800mah battery. It fits in our original case, snug, but fits.
Before getting the battery, odin back to FC09, boot up and synch PRL and profile. Then odin CWM and flash the current AOKP build for Jelly Bean. Only restore SMS and/or call log from backups if you must. Doing those steps will ensure you have a clean install and anything affecting your battery will either be a rogue application or the battery itself.
Gotta be careful with the Gs2 battery. The Tmobile version doesn't fit our phone. I would play it safe and get the epic touch battery.

It's called "fast dormancy" it's a feature which puts your data connection into different states to avoid excessive battery drain.. it's actually very helpful in maintaining battery life. Do a Google search for "fast dormancy" there a a bunch of XDA threads explaining everything.
I do admit it's sometimes quite annoying. While I am tethering, I simply open a command window and ping Google endlessly. It keeps the connection always on. Annoying but it helps. Sometimes I don't even notice a difference.

Have you tried changing your screen timeout settings? I know on certain devices that the data wont slow until the screen is off.

Dude, data cutting off aside, that's supposed to happen as others have mentioned. Think about what you're asking, you want to constantly keep 4G connection even when you're not needing - that makes no sense. Does a bullet train go 200mph when it has no passengers? That's what you're saying.

Yes I understand there would be a significant battery drain but what if I could toggle it for an hour while tethering so it would stay on h+ constantly than toggle back go regular way. And the ping someone here mention doesn't work on iPad lol that's pretty much what I want to tether.

short answer .. yes.
I've been working on this for awhile. I personally want it because I get slivers of 4g where I live but the majority is h.(3g) so I'm trying to figure a way to force only 4g(h+) but it's proving quite difficult. It's looking to be only possible via a radio edit. Meaning editing the radio to tell the phone it's only capable of 4g(h+) data connectivity.

Qualcomm released an app for anyone with Snapdragon that will extend your battery life and monitor what you do to better control the processes. I just downloaded it and it is in "Learning mode" so I will be excited to see how much savings I get when it has learned and starts saving.

Tried it. It's pretty much worthless. Turns off wifi when away from your access points, which is cool. Otherwise, all it does is prevent your major apps from updating to a varying degree. It's better to just control this yourself in app settings and "Accounts and Sync" settings. I think the app was designed with people who don't have a clue about Android sync settings in mind. For the type of person who spends time reading Android forums, it's a waste of time. Sorry
If you do choose to use it, be aware that depending on the setting you or it chooses for Gmail, push notifications may not work.

Incorrect. This app has nothing to do with CPU. It automates turning on/off wifi, and blocks or reduces syncing for various major apps.
