Try installing Juice Defender from the Market. Works for me.
have the wifi and 3g on off buttons as widgets on one of the home screens, and turn them off easily when not needed, like sleeping, takes a few seconds to reconnect, saves alot of battery for me

thank you for this. just curious, if we have to use widget to control the connection, what is the policy designed for? do I misunderstand the purpose of that or it IS not functioning rightly?

the policys are for automated controls, so its meant to turn off after 15 mins or whatever, i keep it as a widget so i can turn them on and off manually as i generally have the wifi or 3g on all the time for gtalk etc
i turn the 3g off when going under ground, sleeping or in a meeting where i wnt be needed it. its easier to do manually then wait for the automated to kick in in my oppinion

i do want it automatically turn off the wifi for me. i think my problem is that even i set it to "after 15 mins", the wifi is still on even after 20 or 30 mins after i turn off the screen.
Usually it will stay off until you awaken the screen (phone) by which time it will try to re-enable itself for your convenience.

i tried the setting in Nexus as well. In Nexus, it is not "after 15 mins", but "when screen turns off". unfortunately, even you check the wifi status after you turn off the screen 10 mins later, the wifi is still on.. totally no idea how that is supposed to work..
How are you checking whether the WiFi is on? By waking it up again, or seeing whether it is connected to your router?

Yes that works for me to, just a simple quick press on or off and no worries about it using battery life when you dont want it to.
Hey everyone
Does anyone here use tasker or have any recommended profiles to help save battery life?

Try Juice Defender with 3g control enabled.
I have mine set to enable every 30mins with good results..
With LOTS of syncing enabled, i get roughly 1% an hour decrease whilst on standby!! Unplugged at 1am on 89% when i went to bed, at 9am when i got up it was at 81%...
Hope this helps!

Tasker data profiles are better than Juice Defender
JuiceDefender has some annoying bugs in it at the moment (some like issues it has with lockscreen/display timeout) have been around for 4months+ and they still haven't sorted them out) so I've switched to Green Power which seems to do the job very well. Simple and no fuss.
Hi. Anyone here good at creating profiles?
I would like some help. If i want a profile that:
IF screen has been locked for 1 minute, i want WiFi to shut down.
And when i unlock the phone again, i want it to turn on.
But - i don't just want a "toggle wifi by hitting powerbutton"-function,
I only want this to apply if i had wifi on in the first place.
The reason i want this profile is:
If i forget to charge the phone at night, and have wifi going, i have 20% less battery when i wake up. Or if im at a friends house, connected to a wifi... well, same here. If it just lays in my pocket connected to X, i want it to shut down when screen is off. Saves alot of juice.

why dont you use tasker for that,
you can do almost anything with that app.
Creating profiles in tasker isn't a huge difficult task, its easy, Just use trial n error to see if it works.

Why don't just use the stock android checkbox in settings that's there for that? o_ô
Go to settings/network and wifi/wifi settings/hit the menu button and tap advanced parameters/wifi sleep politic/check "when screen goes off".
It does exactly what you described...

Well mine is working fine, no draining at all (wifi on 24h24 with this option checked and my phone drain only 1% every 5 or 6h if the screen is off). The thing is that it shut off the wifi only if no app needs it, so my bet is that those who have a battery drain just have some apps that don't let the phone going in deep sleep.

Hi, if you try LLAMA app instead I could talk you through it (as your not getting an answer you want).
As far as I can tell, LLAMA can do everything that tasker and locale can do but its free. It's also very good on your battery and can use cell towers instead of gps for location.

Not sure if I'm in the right place, new to smartphones. Got myself a Galaxy S2 and rooted it. Main point,
I'm using Tasker and I'm trying to have it set so that it's in Airplane Mode when I have an Alarm set so I get no calls/texts during my slumber.
So far, best thing I've done is the phone goes to Airplane Mode between 00:00 and 0600 everyday as well as when light levels are between 0 and 28 - not sure if the light levels are like, set too low.
So far I love Tasker but very little support online and Tasker Wiki doesn't really help. Trying my best with the trial and error method.
Thanks

It is possible to put our 3g radio on deepsleep like our processor without losing connection? Think about an awesone battery life with that OMFG

A CPU in deep sleep does not calculate.

Fill in the blank and find the problem. (1 point)
uhh no. Cel networks needs to poll the device to know which cel its on.
Try sleep settings on a ROM like AOKP. I dont find it worth it as it takes 20 seconds to re-establish any data connection from '2G only when sleeping' mode.
The information in here is only tested on the ICS (Stock based roms) and (stock or repacked kernels). It's not been tested on any other roms. So, if you want to apply the tweak that I provided in here, do it with your own risk. I'm here to help or share the good and bad things but not responsible for any bricked phones.
Update: Wifi Sleeps well! But you need to understand what's going on here.
We are expecting wifi to sleep when the screen is off and 'Keep Wi-Fi on during sleep' is set to 'Never'.
But wifi does not go to sleep mode even every options are satisfied on ICS stock roms with Stock or Rogue repacked Kernel).
I tried many ways to make it sleep (from settings, from build.prop tweaks and from through the init.d script) but none of those worked. Only the way to make it sleep is turning off the wifi manually before turning off the screen.
There is one workaround that making the wifi sleep during the screen off. The method is using Wifi Fixer app from google market but it does not work 100 %. Sometimes, it makes wifi sleep but other times, nothing happens.
So, anyone who is expecting wifi sleeps by any tweaks or by wifi option changes, don't expect it any more. There's no hope yet. For me, I'm waiting for the next build to test this function out.
There's some additional information at http://forum.xda-developers.com/showthread.php?t=1625299 and check wifi section.
If anyone knows the method to make wifi sleep on stock rom/kernel, please post your info here. There are some tools that we can use to check wifi is sleeping or not during the sleep mode. I'm currently using Battery Widget Pro.
Because I've tested lots of things so far, if you know the methond or if it works on your phone, please show how it works and screenshots if possible.
[Update] Wifi sleeps finally as I wanted!
OK. Here is the story.
One specific app mis-led me to wroing conclusion - Battery Monitor Widget Pro (v2.2.4). This app shows that wifi is always on if wifi is turned on. This app does not exclude the time wifi was turned off during the sleep mode.
Plus, there's some pre-allocated time to make the wifi sleep after the screen turned off. For most of Android phones, it seems like this value is 15 minutes. So, even the screen is off, wifi does not enter to the sleep mode immediately. Phone spend 15 minutes after the screen off, and kill the wifi session if wifi option was set to never (keep wi-fi on during sleep).
How to check whether wifi sleeps or not :
Do NOT use Battery Monitor Widget to check the wifi status.
You can easily check it from the stock Battery app. Settings > Battery > click on the graph > check wi-fi status if there is any gap (means sleep or turned off).
Then, How to change the default 15 minutes value to make the phone sleep early?
Update 5/16/12 - Fixed wifiSleepWait tweak, so it works without any manual database handling. The below is just for informational. Now you don't need to manually create a row into the table.
There were one or two information available on XDA but nothing is correctly applicable to Epic 4G Touch. So, here is the tweak that I made for E4GT.
To do this you will need root explorer -
1. move to the folder, /data/data/com.android.providers.settings/
2. copy the databases folder to your /sdcard
3. Move to /sdcard/databases click settings.db
4. select secure
5. it will ask you which editor you are going to use. If you installed sqlite then select sqlite, otherwise use root explorer (only at first time)
6.Check if there is column name 'wifi_idle_ms'. If there is, then change the value to whatever mili seconds you want. For example, 10000 = 10 seconds, 30000=30seconds. If you want to wait 15 minutes until wifi sleep, then 15*60000 = ?
7.If there is no 'wifi_idle_ms' row, the click long time anywhere on the table. It will show you the actions, select new record. Do not change _id, put the 'wifi_idle_ms' in the name field (without quote sign) and put the value explained above. For me, I just put the 10000 (for 10 seconds). Click save.
8. Now you can see the value changed or row created. Exit editor and move up to /sdcard. Copy (or Move) databases folder to original location (/data/data/com.android.providers.settings/). Sometime, the copy is not successful because database is currently being used. If it's not copied, then try it agaon to copy until it's successful. For me, it was successful on second try.
9. Reboot the phone and click the power button shortly to change to screen off mode(sleep mode).
10. After the time passed defined in above, click the power button again and notice that phone was working on 4G or 3G mode and not wifi mode. Phone will try to reconnect wifi after the screen turned on.
11. That's it. Now you can change the idle time until wifi turned off as much as you want.
The above was the manual way to change the wifi_idle_ms value from database. But there is another way to change this values automatically. The method is using sqlite and of course you need to know the sql query.
In my case, I tried to add this sqlite query statement into my init.d tweak but only update sql command worked and insert was not successful. Maybe I need someone's help to get this insert statement successful.
In here, I'm adding only the update tweak which can be added into init.d. What this mean is, at first time you have to insert the database row manually but once it's created, you can update the idle value during the boot thru init.d script.
Because you don't need to run this init.d script everytime on boot, once you update the value, change the permission to 644 and it won't run again until you change it back to 755.
To run this init.d script, you will need sqlite3 - http://chensun.net/android-development/install-sqlite3-on-google-nexus-one/54/
Download it and simply move to /system/xbin foler. Assign the same permission like other files on the same folder.
Of course, you also need root access and busybox.
The init.d script will be found at http://forum.xda-developers.com/showthread.php?t=1625299

Maybe it cannot sleep when sync is on?
I imagine that wifi is needed for weather/news/etc updates and clould2device services.
Wait...the options are changed on ICS correct? Meaning its never off during sleep on Gingerbread and always on during sleep on ICS or am I not understanding?
Huh? Mine sleeps just fine unless I set it to never sleep.
That aside - you are aware that you're better off leaving wifi on anyway, right? It uses less battery power than the cell radio does. Just an FYI
Finally figured out everything!
Took whole one day to find out everything!
First, most importantly, WiFi sleeps!
I'm going to explain what happend and how we could make wifi sleeps better in op section.
edit. Partially updated. I'm checking now if I can make a script to change the leading time that is required before wifi actually sleep.

I think there is a little difference of understand about what has the control over other services/fuctions.
Usually weather/news apps are dependent on wifi or 4g services. Those apps usually do not control the wifi or 4G and many times only able to communicate wifi or 4G are turned on. Those services cannot hold the wifi/4G connections even those services are still running.

That's not true. It's totally based on the signal strength. Usually 3G is not fast but do not use battery as much as wifi when the signal is weak on both wifi and 3G.

will this tweak work if I set wifi to "only when plugged in"
edlivian said:

Click to expand...
Click to collapse
I think the right answer is No.
When phone is plugged in - wifi is always connected even after the screen turned off. So, this tweak would not work while phone is plugged in.
When phone is unplugged - wifi will stay offline always. So, this tweak is not applicable.
If you set the option to "Always" - wifi will stay connected during the screen off. So, this tweak does not work.
If you set the option to "Never" - This tweak only works for this option.
The purpose of this tweak is minimizing the waiting(idle) time until wifi moves to sleep mode after the screen turned off.

For this, I believe it's related to the value of wifi.supplicant_scan_interval which is normally defined at build.prop.
Check out the value from there.
These days the value 180 (3minutes) are normal for tweaking purpose. But for EPIC 4G Touch's case, it's default is 5seconds (causing lots of battery drain if you are moving around).
For example, if wifi is not available from some location, then your phone will try to searchthe available wifi network after x amount of times. If this value is too big, then it will look like wifi is not connected (so most of you, just try to reconnect the wifi manually before time comes). If the value is too small, again it causes the battery drain.
Once the wifi is connected, it keeps the connection based on the wifi policy. But if the connection is lost, then it will try again to search!
First of all, REALLY REALLY REALLY Really thank you for the reply mate.
My wifi supp value is set at "10"
I know this value only works when there are not any "known" access points in range.
The thing is, that it NEVER connects with screen off or on when i get back in range.
It only does it when i go to wifi settings (refreshes the list and connects without touching anything more!).
(of course, my wifi battery saving policy is set to "never" while screen is off)
Wifi stays on but it freezes AP scanning, while screen is off i guess.
Would a logcat help? Any tips about how to capture a good log about that issue?
Hi guys, I hope some of you are experiencing the same issue and can help me to figure this out. Here it is what is happening.
My WiFi in advanced settings is set up to be always on only when plugged in. So the phone goes to deep sleep, turns off the WiFi and turns on 3G data on network. The problem is after that the phone doesn't pull off messages and push notifications (Gmail, WhatsUp etc) and when I wake up the phone and he connect to WiFi
he is pulling the messages. And that is happening only if I am in range of remembered WiFi network. If I am not in range on some saved WiFi network the 3G data pulling works as it should (pulling the messages as they arrives).
I tried to put the phone in Normal Mode under Power manager but nothing is changing.
So any of you guys noticed something like this?
deep sleep
Same issue...wifi or only 3g either.:crying: no idea and i hate it... i turn off the screen and after 15 min it goes to deep sleep and no notifications but just...once or twice a day....strange. i checked every energy management option but ...dunno.

This happened to me last night, I'm on B512 and it hadn't happened before. Did you ever fix this, @goce.nakov, @marilllyo?
Is this supposed to happen in deep sleep? Unlike your case, my Wi-Fi was off and I always have a good data connection, but I only got the notification when I turned the sreen on, about an hour after the notification were supposed to get to my phone.
