WIFI is always ON! - Galaxy Note 3 Q&A, Help & Troubleshooting

Even manually by disabling the wifi, in the chart of the battery, I see that is always connected, even at night, even when the display is turned off, even when there are no other activities!
How so?

Settings->Connections->Wi-Fi->Menu button->Advanced->Turn "Always allow scanning" off->Hit the thanks button!

I thank you on trust!
This should also consume less battery power or does not change anything?

By changing this I'm now getting about a quarter of a day more. Not a lot but more=better!

Tomorrow I'll know!
Whether you finally wifi turns off completely ... whether the battery lasts longer!

The WIFI locking it manually, is finally off!
Unfortunately I have not noticed improvements with the battery.
But I believe that the increased consumption is due to the data connection.
In fact, if I leave the wifi on, in addition to the data connection, I have a night consumption by about 4%.
If I turn off the wifi and leave the active data connection, I have to consume about 10%

At night, I just turn Airplane Mode on, WiFi on, 3% consumtion.

I will try to turn off the data connection only because I need the radio active to receive any phone calls.

WiFi connection ever ON (is it possible?)

Is there a trick for mantain the wifi connection always on?
Because if i switch off the phone i loose my connection and the p3600 use the gprs connection for recieve the mail in background.
Thank you
That would kill your batteries very quickly...

Yes it would. When I'm at home I plug in my Trinity into the charger, which makes it stay on. I have the phone set to stay on while charging. This way I can have my wifi connected continuously and save on my 3G data usage.
I think when in standby the phone doesn't connect to data, it wakes itself up does the email check etc., then goes back into standby according to your power standby settings.
I've noticed that when using Wififofum, it still detects new wifi access points even when it's in standby.I don't know if it's really in standby, but at least the screen is off and i need to press Power button to see what it has found.

Wifi wont turn off in sleep mode

Hi Guys,
I got my HD2 today and i have to say i am impressed!
I only have one problem which i am not able to resolve.
When i turn on WiFi, it wont turn off during sleep mode (when i turn off the screen). i need to manually turn it on or off. this is how it came out of the box.
I wonder if other HD2 users are having the same problem / found a solution?
I tried advanced config tool, and i unchecked the "wifi during sleepmode" setting, but after each reboot the settings just come back.
Any help would be appreciated.
Hi mate, you should look this

I thought that guy just want to keep WIFI on but you did.
thanks man but it does not help me with my problem. I cant seem to be able to get WiFi to auto turn off when in standby. the reg tweak will work until you reboot the device. after reboot the WiFi again won't turn off when in sleep mode unless I manually turn it off.
Bump.
Can any other HD2 owner please confirm if this is happening on his device too?
Same problem.
HDtweak and AdvanConfig does not work. After soft reset, wifi-on-standby is back ON (checked).
Been trying to find a Auto-Disconnect for GPRS(HSDPA) but the above 2 apps does not work too.
have you tried to change wifi power settings to high? I think it does work then. I guess the medium setting is something special...it keeps the wifi connection alive in standby, but also doesn't consume much power. I have an exchange connection active, so i always need an internet connection. The moment i turn on wifi at home, it stays on, even in standby, and my data connection over 3G disconnects. My exchange still works perfectly...and no huge power drain! My wifi power setting is on the medium setting...
Yes, I can confirm I'm encountering this issue too - on my HD2.
Strange, 'cos I wasn't at first, I'm sure - I remember the wi-fi notification icon flashing when resuming from sleep.
glenner05, can you confirm that you can get wi-fi to sleep please?
Hmm.. thought it might be connected to the htckeepwifionwhenunattended registry value but mine's set already to 0.
There're others trying to do the opposite!

Anyone else found a solution?
I think HTC made this by design. If you turn GPRS data off and leave Wifi on while in standby you will be surprised how low the power utilization is.
I tested and with GPRS data off and Wifi ON, in standby you lose about 2% battery per hour...that's nothing.
It seems that on the HD2 the Wifi power consumption is really optimized so no real need to turn

Mine is on default Wi-Fi settings and when it goes into standby, wi-fi goes off.

Yeah goes of in sleep mode, if you get wifi toggle, you can choose to keep it on or turn it off when you like .
Shame the grps is still a problem....
pgamble and jrvenge: you really mean wifi switches off on the device when it goes to sleep? Ie. you see it disconnect from your router or something?
jrvenge: what did you mean by, "if you get wifi toggle"?
clubtech: when I read your post I agreed with you, maybe. I can't now be certain I remembered correctly that I'd seen wifi reconnect. And yes, the power consumption does seem low
There is a cab floating about here that enables you to force the wifi on always or turn it off.
If you forc on it stays on, if you turn of it goes off.
Return to normal and the hd2 does its power saving thing, so im all sorted there, just need a timeout on the gprs now.
If you cant find it let me know. It works a treat.
can youplease post the cab ? I have been looking for something like this .
Sure pm me your mail and i will send it
GPRS Disconnecting software here fella's, tested and working on my HD2 100%
May also turn off wifi but i've not loked yet, just about to leave for work so will check later!! lol

Ok just tried and it does not do what we want with WiFi
Yes ... if device goes to standby, when it comes out .. you see wi-fi searching to connect again ... so it definitely disconnects and the reconnects when it comes on again.
Paul.
Yup your right!
If it's in balanced or best battery mode then it turns off in standby and reconnects/searches again when you press a button to bring up the lock screen.

Holy crap. Change wifi sleep policy to never. BIG INCREASE IN BATTERY

I'm not sure if anyone else knows this, but I read somewhere that if you change the wifi sleep policy to never, it actually SAVES battery.
I thought this was insane, but if you think about it it actually makes sense. It stops your phone from the constant switch to Edge and 3G... which in return saves your battery.
Usually I can lose up to 5% in 30 minutes by not even using my phone.
Now that I have a constant wifi connection I have only lost 2% in an hour and a half.
Assuming you're connected to a wifi network, yes.
Otherwise, no.

I use Y5 which uses cell towers to remember where I am able to receive wifi. If I leave a remembered spot it will turn off the radio for me. When I come back it will automatically turn it back on and reconnect.

Hmmmm
Wouldn't the phone continue to have it's cellular Edge/3g connection going while you have the WiFi on?
Whenever I have WiFi on in addition to 3g I always see, under battery usage, wifi at about 2-3% and Cellular signal at 5-6%
Seem's like when you have WiFi on as well as Data that both are draining the battery...
The phone turns off 3g radio when you have a data connection.

Are you sure about that? I'm connected to WiFi on my phone and the Status screen under About Phone still stays UMTS rather than EDGE.

UMTS is just the 3g network, that doesnt mean data. the 3G network is used for voice calls too.
so yes, when the phone is connected to wifi, the cellular data connection is terminated. always been like this.
and yes i've seen a huge battery increase with wifi set to NEVER sleep policy.
It will stop hop between 2G/3G even if you're not using the data. You'd have to force it to 2G only and then enable wifi to take advantage of this the most.
I second those findings. When at home, use no sleep policy, and going out - turn off wifi manually. Works very well.
My "always on while sleep" doesn't work.. it opt's out anyway..
Edit: Installed an app called Wifi Fixer. And my connection hold up now while sleeping. nice....!!!
Where do I find this sleep-setting?
Not looking for a flame because I'm still learning.
if you have juicedender and keep the wifi setting on what it is when your phone sleeps the phone will turn off wifi and juicedefender will turn of 2g/3g correct? If this is true then you can save double the battery by installing defender (free); right?

Go into Wi-Fi settings.. Hit Options (the capacitive button you know...)
Ha! I've had my N1 for two months now and didn't realize there was more Wifi options if you click on the options button to the left of the home button. I wish they would add some sort of indicator that there's more to do if you click on that button. I've run into this soooo many times. It's kind of nice, though, because I keep finding goodies even months after buying the phone lol.
Yes it's often a mystery - it would be cool if it was possible for the capacitive menu button be lit only when there are additional options.

I tried that on a hottie standing in line for coffee. I got slapped.
I've tried setting the wifi sleep policy on my phone (T-Mobile MyTouch Slide) to "never sleep," but I'm not sure it's helping. When I turn on wifi for a little while (say, an hour or two) and then look at the battery usage screen I see that wifi uses a pretty significant chunk of the battery, maybe 10% or so, higher if I leave it on for longer. This is even if I'm not using the connection much, sometimes I'll turn it on to do a little light browsing and then put the phone away for an hour and then check to see how much power the wifi connection ate. Today I turned on wifi for maybe 10 minutes to download a couple app updates and turned it off right afterward. The phone has been only off the charger for 3 hours, but wifi accounts for 8% of the battery drain (the rest is idle: 16%, standby: 31%, and display: 45%).
On the other hand if I stick to 3G data I don't feel like I see as much of a hit on the battery (though it's harder to tell how much of "standby" is going to 3G data).
I understand in theory that connecting to a wifi access point within the building should require less power than connecting to a cell tower a mile away, but I also disable "always-on mobile data" so hopefully I'm not maintaining a 3G data connection all the time either.
Those of you who leave the wifi connection on all the time and are reporting better battery life than with 3G data, how much of your battery do you see going to wifi in the battery usage screen?
Well for me when I leave WiFi set to never, I lost 11% in 12 hours. On 3g I lose way more in that same period.

(Q) wifi & airplane mode

wifi nexus 7. turn on airplane mode. manually turn wifi back on. what stays off, anything? GPS? Does airplane mode have any use or advantage on a wifi only device. Any battery use changes or background processes that stop? Thanks for any responses

Probably no bluetooth, either. I know it turned it off on my old work blackberry because it was on the same screen and you could see it turn off.
It should turn off EVERYTHING wireless. That includes, to my knowledge, WiFi, GPS, NFC, and Bluetooth.
It should help with battery life - although probably very slightly. GPS/NFC/Bluetooth truthfully have very little effect on battery life as is, and WiFi isn't that big of a hog. But it certainly could help to eek out an extra few percentage points if you *really* needed it.

[ TIP ] Save Battery By Keeping Wi-fi Alive

This tip is one that seems counter-intuitive, but you can save a lot of wear and tear on your Android phone's battery if you tell it to keep the Wifi radio turned on and connected while the phone is sleeping. Your phone needs a lot of juice to keep pinging those cell towers, and even more to transmit data to and from them. Wifi radios use much less power because of their design, and they don't have to keep searching for a better access point. It's the way cellular data communication was designed, and it's a necessary evil.
But what if you're spending all day (or all evening) in one place, connected to Wifi? If you tell your phone to shut off Wifi when idle, it bounces back to cellular data (be it 2G, 3G, or 4G) and starts sucking down the electrons again when the screen shuts off. That's no good, and easy to fix:
Open the advanced Wifi settings by pressing the menu button, then Settings, Wireless & networks, Wi-Fi settings, and tapping the menu button again. You'll have a choice to either Scan, or go Advanced -- go Advanced.
Tap the Wi-Fi sleep policy entry, and you'll get a pop up dialog with the 3 choices. Choose Never.
Now even when your phone goes into standby mode, you'll stay connected to Wifi and be able to get mail and messages without turning the cell radio back on and trouncing your battery life. And for the times when you're not in an area with a Wifi connection, just shut Wifi off, either through the menu or with a handy toggle widget. Your battery will thank you for it.
#Its only for those beginners who dont know about this setting...
dont you mean tick always, as if you tick never itll go back to using your dataplan instead of the wifi
Re: [Guide] Save Battery By Keeping Wi-fi Alive
I use to believe this but for some reason on my sgs3 wifi drains more battery I get more juice with wifi off.
Results may very due to your services supporting fast dormancy, etc.

You need to choose "Always", not "Never". If you choose "never", then it disconnect wifi as soon as display is turned off.

If you're moving out of wifi range, or in and out of wifi range, turning wifi off will use less power as associating with an AP has a high energy cost. But as the original poster says, if you're going to be sitting in one place all day e.g. at home or at the office where your phone will always be connected to an AP, leaving wifi on and always connected will use less power than 3G.
More details here:
http://people.cs.umass.edu/~arun/papers/TailEnder.pdf
I suppose it's not that surprising. I'm sure many of us, after buying a new phone, have left the old one sitting around at home without a SIM card but connected to wifi, still polling emails and everything. The battery lasts ages!
Re: [Guide] Save Battery By Keeping Wi-fi Alive
This might be irrelevant, but i red an article her in xda about modern mobiles battery long time ago.the article said that when wifi on or off has no significance effect on battery life (regardless of other sitting like carrier signal .....etc)

Apparently FD doesn't affect battery life that much (See here, second post). I get better battery life on wifi and I think that's still the case for the majority of people if they are within a wifi area.
I tried and with option "always" I have more battery drain, cca. 2%/h in idle/screen off/overnight. With old setup when Wi-Fi is off in case screen goes off, I have cca. 1.6%/h. So, it doesn't work for me. Thanks anyway.
What ive found is to turn your 3g to 2g, that will save a LOT of battery. I use 3g if im out and about where theres no wifi, if im at work i dont use my phone often so switch 3g to 2g. It still brings my notifications in time. And at night switch to 2g as well.

But that's a no brainer! Of course battery life will last a lot longer on 2G! Your battery life will also last a lot longer if you have no data connectivity. The discussion here is between data and wifi.
