Is there a particular app available for this scenario? - T-Mobile Samsung Galaxy Note II

Is there anyway to turn on the data connection automatically whenever a particular app really requires it (and turns off when the app is exited)? I mean, this might conserve more battery life for me. Not a bad idea even for those that are data-conscious.
Preference, (Without Root; Plain Stock)

JuiceDefender or Tasker. Tasker is more complicated and it takes some time to learn.

you can set up an NFC tag to launch the app and turn data on and then another one to do the reverse...

Anyone Using Tasker?

Anyone here using it? what is this app for? is it worth buying? does it give u battery life? im really interested but i cant find no videos on it on youtube. please share your thoughts.
It is worth every penny. The best app for android IMO. It is not very easy to master it, but even the basic stuff has made a vast difference too the behavior of my phone.
For example, I have extended my battery life to 38 hours simply by having it automatically go into airplane mode between midnight and 6am.
It will turn off wifi, back screen brightness down, change screen timeout to 10 seconds and give me a notification popup and sound when my battery drops below 15%.
It will turn on gps when Wavesecure is activated, something Wavesecure can't do by itself.
It will turn my ringer off when I get within 200m of the two cinemas I go to.
It turns wifi on when I get home, and off when I leave. Same for work.
It loads my music app when I plug my headphones in.
Tasker can make widgets! I have one set up to (with one press from my home screen) turn up screen brightness, turn on gps, turn up speaker volume to max, wait 2 seconds, then launch google navigation. It will then turn everything back when I exit out of navigation.
It will, on weekdays, text my girlfriend at a certain part of my journey home after work. That way my dinner is ready when I get home!!!
I would say try out the free 1 week trial. There is even a wiki and web site with extensive instructions and examples uploaded by other users. You can also import profiles as well as create your own. The really handy ones I have exported to my sd card, and e-mailed them to a friend when he bought Tasker. Not sure I helped him though as there is a steep learning curve for this app, and it is worth being patient with it to learn its ways for yourself.
I think it is worth much much more than the asking price.

wow sounds sooo nice . i already bought full version yesterday but havnt even opened the app once . well i did open it once it seems hard to understand lol . so for all this task does the gps need to be on? or not? and can u turn off 3g?
You can turn off APN, but don't think that works well in the UK. Sorry, my knowledge of 3g is limited.
Basically, you can have tasker turn on and off nearly any feature of your phone that your want. There are two sides to tasker. The "Profile" and the "Task".
I have found it is best to first set up the "task". Say you want to save battery power at night. Select the task button and select "new". Call it "power save" or something. Select the + symbol and select "Net". In this menu, pick "Airplane mode" and select to ' on'. Then hit ok, then save.
Now to create the 'Profile' where you define the contexts that will activate the "power save" task you just created.
Select 'new' then select the 'time' context. Enter the time you would like to have your phone go into airplane mode. After hitting 'ok' it will take you to the profile page where you set up what now happens between the times you just specified. From the drop-down at the to of the page, select the "power save" task you created earlier. Hit 'ok'.
Done. Your Tasker will now shut off all your radios between the times you entered.

Worth every penny. I use it to:
- turn on GPS for programs that need it (turns back of when editing the program)
- turn notifications off when starting desk clock
- change volume when connecting head phones
There are endless possibilities, try it and then buy it.
i've bought it for little things but want it to be able to handle 3g data which it doesn't
i,e turn on wifi, if no conn after 10 secs, turn on 3g, auto sync for a min, then turn data off.
works fine and dandy with wifi, but not 3g.

You need APNDroid to disable 3G.
tasker really is worth every penny!
Wort every cent. Must have
I used to check periodically (every 3 minut) if my car Bluetooth near. If yes connect and and hold on the connection. If disconnect wait 15 minutes and seek again... save really battery... fantastic...

Wow sounds like you have a good understanding and has some good stuff. I don't know if you can, but I posted a page where maybe people can leave profiles for those of us who are a bit more chronologically challenged.
This is the greatest
I use tasker for everything. I am very forgetful so I have it pop up astrid tasks when I leave the house or work. The quiet mode works well for work and there is even a way to auto check in to foursquare.
Worth every penny, it makes your phone 10 times better and is a must have app.
I have profiles that do the following:
-During work hours and within range of the office set Vibrate, turn off wi-fi.
-When within range of home turn on Wi-Fi
-If at home after certain time in evening go silent
-When leaving car (detected by bluetooth connection to stereo), store time and location. Have icon on desktop to retrieve info and show on map to find car.
-When on call (by checking diary) if a colleague calls always ring regardless of silent.
-Say caller/texter name
-Send magic packet to wifes phone to report location and show on map (handy when shopping)
Plus many other scripts....
I find that this program has a pretty high learning curve...
Is there a wiki I can read up or a way to import other people's profiles?

Using "Cell Near" instead of GPS
I was using Tasker to turn WIFI on and off based on GPS locations. However, I found an alternate method that does not use GPS calls (and waste battery use). Instead, I am now using "Cell Near" to find the cell tower near home and turn WIFI off when I am not within distance of it.
I have posting walkthroughs of all of the most useful profiles I have collected. Check it out at http://dbilliter.blogspot.com
Tasker rules my phone... With all the taks i made.... Love the app!!!
You can do almost everything if you know how to use it... Little variable programming and your phone will get his own life haha...

[Q] Save battery by turning off mobile data (Tasker)

I'm trying to figure out if it's worthwhile to turn off mobile data when the screen is off, and turn data back on when the screen is turned on. It would also be necessary for me to occasionally switch mobile data on even when the screen is off in order to check email. (I'm thinking something like 15 minutes off, 3 minutes on)
Does anybody have any success stories or advice whether I am likely to see any noticeable battery savings by doing this?
I started doing this from when I first got my evo. Just turn off mobile data, you can still get texts and make calls, and then turn it on when you need it. Also turning off background data in settings also adds additional battery, but just enable it when you need the market. I went most of all day with about 80% of my battery still good between it just being off, using the mobile data here and there, and some texting.
Edit: I don't use a tasker, I just use the power widget in my notification, so I can turn on my mobile data on/off with just a tap. And if you're like me you don't know when you actually need it or for how long. So I find it easier and more effective to do it manually.

X2, i use switch pro to toggle mine. Battery drops about 2% per hr while data is of with screen off even when listening to music from my play lists.
I turn off the "always on " mobile data and noticed a big difference. The data turns on and off with the screen.
Sent from my Evo using Tapatalk
Over the months I have been an Evo user, I have collected some valuable information that all users should probably know in regards to maximizing battery life. Besides the stuff about 4G and a few specific options, these steps apply to pretty much any other android phone running 2.2, and a lot of them apply to versions below Froyo.
General Lithium Ion Battery Information
^^This link includes stuff about charging, including trickle charging aka SBC (Why NOT to use it, or at your own peril)
My tips for good battery life:
Tips for Non-Rooted users:
1. Turn off all radios when not in use.
(gps, Bluetooth, wifi, data, 4g) Use a widget like the default HTC power widget or Switchpro from the market. The radios of the phone draw power if on even if the user isn't actually utilizing the radio's functions.
To manually turn off radios without a toggle, go to menu>settings>wireless & networks.
Wifi uses less battery than 3G, so use wifi when you can.
**IMPORTANT DISCOVERY**When you turn on your 4G radio, then turn it off, it will keep scanning and turning off all by itself.
The problem is apparently exacerbated by a 4G toggle widget, which causes the phone to automatically turn on 4G at boot. This repeating of scanning and disconnecting severely drains battery life, and sadly, no matter what ROM or kernel you use, there is only one way to fix it:
-If you don’t use the toggle widget, then you have to reboot your phone after turning off 4G
-If you do use a toggle widget, then you have to remove the widget from your homescreens, then turn off 4G via settings, then reboot.
**To check to see if this is happening, download alogcat off of the market. Look for the lines saying: I/Wimax ( xxx): <DC> Try to establish a connection to DC server.
E/Wimax ( xxx): <DC CONNECT> IO error: msg=’/xxx.x.x.x:xxxx –
Connection refused’
Over and over again.
2. Juice Defender is one of my favorite apps. Basically it controls your data for you to maximize life.
More explanations are on their page, search it on the market for free, or upgrade for more features.
Here are my settings for it: Click me
Note that for me at least, juice defender likes to deny apps data privileges whether you allow them or not, so screen on = data on works best for me.
3. I love live wallpapers, and I’ve always been a fan of pixel zombies, but they are really only good for showing off due to their battery drain.
4. Go to menu<settings<wireless & networks<mobile networks<disable always on mobile data.
Product F(RED) said:
To clarify, "Always On Mobile Data", when turned off, lets the 3G modem go to sleep after the screen has been off for 5 minutes. It doesn't interfere with anything like email or any other application that requires an internet connection at that moment because it turns on on-demand rather than being on all the time and wasting battery.

5. Set your screen timeout to something that fits you
This will prevent your phone from staying on when you don’t manually turn off the screen. Also with this, manually turn off your screen when you’re done with your phone.
6. Everyone has that issue where the first ten percent go the fastest.
This is due to two things. One is that these types of batteries stop charging once they get to 100% to prevent damage, and begin charging again at 90%. This means that you could potentially unplug your seemingly fully charged phone at 90% actual charge. The second is number 7.5.
6.5. Use the trick described in this thread, it works.
My idea behind how often you should do it is once a month, if you flash a new ROM, or if you stop noticing the benefits.
This is the calibration technique recommended by HTC themselves. Check it out!​
7. Task killers used to be the shiz, but no longer.
Here is the ultimate, in depth, graphically assisted, explanation by the famous Fresh ROM's chef, Flipz. Shortly, in light of recent testing, really don’t do anything but force apps that the android OS needed to be open, and thus didn’t close, to re-open. So try not using them, unless for stuff like trying to figure out why your phone isn’t sleeping with system panel. You really won’t notice a performance difference, and the adverse effects you aren’t seeing will stop
+=+ A good alternative is the application SystemPanel Pro. It has a free version, but I highly reccomend purchasing the paid app. It basically monitors everything going on with your phone's usage both in real time an in terms of usage history. If your battery is draiging fast, it tells you what app was doing it, how much it was doing it, and allows you to stop it.
8. People posting screenshots of the Battery screen as proof of long lasting battery are giving statistically irrelevant information.
See HERE That screen shows time since last REBOOT, not last charge. This isn't always the case, but a lot of people will post a lot of things about battery life, but look for definitive screenshots and testing results before you break down and cry due to the poster's life and yours.
9. I'm sure you have all heard around that your phone isn't "sleeping".
This is referring to the phone's "awake" time, hence the name. When you go to menu>settings>about phone>battery, you can compare the two numbers, "up time" vs. "awake time." Generally, up time refers to the amount of time since the last reboot. The "awake time" is how long the screen has been active. The problem is, a lot of the time, due to the endless possibilities of inconsistencies between apps/ROMs/kernels/phones, the phone will not go to "sleep", drawing power proportionate to the screen being in use when it reality the phone is sitting idle.
If you compare these numbers, and they are the same, or if you note the difference, turn off the screen for a minute, then re-check and they are the same, then your phone is not sleeping.
One solution is to reboot.
Usually, SystemPanel will show an app that has gone "rouge" and is keeping your phone awake.
Uninstall applications/reinstalling them slowly, checking after every install to see what is causing it is one tedious but surefire solution.
Lastly,
Follow these steps that I have discovered almost always work.
1. Reboot phone.
2. Instantly upon reboot, as soon as you gain control, open up some type of monitor/taskkiller
3. "kill all" tasks on startup; about 5 times in quick succession should do the trick.
4. Turn off the screen and leave it for about five minutes.
5. Check the up time v. awake time and see if they are the same.
6. If they are, repeat steps 1-5. If they are different, you are good.
Tips for Rooted users:
1. Try out custom kernels.
By going to the EVO 4G Android Development section of the forums, you can see all of the different kernels being developed. These allow for all kinds of modifications like underclocking the CPU and undervolting, both of which save battery. To see how to use them, read the FAQ's in each thread's OPs.
Here is a great guide to custom kernel's by mroneeyedboh.
2. Use SetCPU in compliance with whatever your custom kernel allows.
This site will explain the basics of SetCPU: http://www.pokedev.com/setcpu/
-Profiles from SetCPU should usually involve these for battery life optimization:
-Screen off at the minimum clock speed for both, with the max raised on level if sluggishness is apparent
-A temperature greater than “X”
-General power related profiles that lower cpu speed at lower battery levels
-Here are my SetCPU profiles: 1 , 2 , 3
-My profiles change a lot as time goes by, because different kernel creators recommend different settings. I suggest reading up on whatever kernel you are using to gather settings.
------------------------------------------------------------------------------------------------------
NOTES:
*Some apps or processes begin to run at startup and keep the phone awake. These apps are not detected by things like spare parts or system panel, unless sometimes represented in the "system" process, in which case its usage will be unusually high.
This shouldn't take more than three repeats, and if it does, you need to factory reset, and slowly add apps back to see what's causing the problem.
___--- When it comes to actually "calibrating" one's battery, there are a couple of methods floating around. The method I first learned is to charge the phone all the way, boot into recovery immediately, and "wipe battery stats". Then reboot quickly, and run your phone all the way to death without charging it, then charge it all the way without interrupting it, and you should be good to go. Do this when changing ROMs/kernels for best results.
----When it comes to people claiming 20 plus hours of moderate/heavy use out of their current setup or other ridiculous absurdities, consider my position: No matter what you do, the Evo battery is the Evo battery. You can tweak it and customize it with kernels, ROMs, and settings, but none of that will turn it into a car battery. The main problem (besides a false sense of pride) that leads to these reports is the misunderstanding of what the usage levels are, so here’s my best summary:
* *Light usage – Phone screen actually on for maybe 4 hours. Things like a few texts, some emails, 20 minutes web browsing, etc.
* *Moderate usage – You watched a few youtube videos or similar apps, sustained web browsing, hundreds of texts, some games. Hours range from about 5-10 of screen on
* *Heavy usage – LOTS of video watching and games, or some high def gaming/movie watching for at least an hour to an hour and a half in total, with lots of emails and texts, browsing, and other app shenanigans
*I’m sure everyone doesn’t agree with all these numbers, but this is most likely a good average of what powerusers think. All specific hourage may vary due to differences in phones, batteries, ROMs, and kernels… Which also means that most battery comparisons are pointless; it’s only what you can improve on that counts!
I’ll update this whenever I see good stuff, people remind me, or I remember/come across things I do.
Hope it helps everybody!

I am the owner of SuttCo. We developed the Locale Mobile Data Plugin (which can be used by Tasker). It has a condition that can keep tabs on your data use and a setting which can be used to shut off mobile data.
I know Tasker and Locale have screen off/on conditions. I don't have time to run any tests for you (busy working on a new plugin), but if you're willing to do a semi-scientific study and report the findings here... I'll comp you a copy of the plugin. Shoot me a PM.

Not to say that turning off mobile data when you're not using it is a bad idea but I've found during my own personal experience with trying to improve my battery life for daily use that using titanium backup to freeze Google Backup Transport.apk is also a helpful solution. Other things that helped are going into Accounts & Sync and turning off background data because believe it or not, that stuff eats your battery up like a fat kid eating cake...hahahaha...Anyways, another tip would be to hit up Display and turn off Automatic Brightness and play around with the scroll until you come to a setting where you can see because I've found that the Automatic brightness eats up your battery too, not as fast but it does! Another thing that I've done is this and although there are task killers that would do this for you....I've decided to do this myself and after using an app such as Facebook or the brand new CNN app, I've gone into Applications and force close them out just to save battery and all of this nonsense I'm talking about has helped me out alot......NOT TO BRAG but using these little tips of mine, I've gone from 2 and a half hours and I was at 70 percent to 4 hours, 36 minutes and 48 seconds and I'm at 68 percent.....and that's with out turning my phone off, that's talking on the phone, texting, checking my facebook, downloading some apps here and there and just leaving it on in front of me at my desk.

I have setup a few Tasker profiles to do this exactly. I did this instead of JD because the free JD doesn't do exactly what I want it to do, and I don't want to pay for JD when I can emulate it with Tasker.
The only thing I cannot do, that JD can, is keep data on while there is an active connection. With JD, if you turn off the screen while there is an active data transfer, it will wait until the transfer finishes to turn off data.
According to the Tasker website, there is plans to make a state/event "connection data rate" which would make it possible to do this. But that has been in their plans for quite some time. (I actually happened upon this post while searching for a way to check if there is an active data connection with Tasker.)
Also, with the way that Tasker views an "Open program", the program has to be open in the foreground in order to be considered open. This makes it tough to keep data on when a specific program is open, unless you're planning on keeping that program in the foreground all the time. To get around this, I created a profile that leaves data enabled while I have headphones plugged in, since I have headphones plugged in while using all the programs that I want to have constant data with.
EDIT: here are the profiles, and the tasks that go with them (I also included a profile that turns off the wifi antenna after disconnecting from a wifi access point.)

[Q] SetCPU and JuiceDefender, are they needed anymore?

Hello,
Title says it all...
I would notice overnight that my battery would be completely horizontal (no drop) and thought it was the combination of SETCPU and JuiceDefender (night profile + screen off drop mhz).
But, after unisntalling them, I noticed the same "flat line" at night and also achieved over 30 hours of battery life.
My question is... do these apps really make a difference on our phones?
Or, are the phones advanced enough to handle everything just fine?
your thoughts are appreciated.
I agree... I got about 27 hours of life out of my battery without set cpu or JD (i've never liked JD anyway because its like putting my kid on riddlin)

Which version of JD are you using? If you have the Plus or Ultimate version, you can probably still gain some benefit, but you need to learn how to custom configure the settings so that you use the ones that are still relevant. For example:
Where Not Helpful: JD will turn off your GPS if an application isn't using it, but most of today's phones will do that anyway.
Where Helpful:: In advanced settings, you can provide a 'night schedule', wherein during this time, JD will disable mobile data, and thus polling, so your phone will not go out and check for mail, FB messages, Tweets, etc. Otherwise, mobile data is off unless you 'wake' the screen for some reason. Or another feature that 'trains' your wi-fi to only activate when you are at home or a 'recognized' wi-fi spot. These are a couple examples, there are others.
Where it MAY be Helpful: JD can disable mobile data for a custom # of minutes (10/15/30/60) and prevent background sync during those periods. It will awake, allow the sync, then turn mobile data off. Now some apps may only sync in these intervals anyway, but unless they're all syncing at the same time, you could have lots of 'up' time. Some of this may not 'wake' your phone from Deep Sleep, but depending on how sloppy the code is, it might.
Hope this helps.

I think really depends on the ROM you are running. ViperROM has a script that changes the CPU speed and governer on the fly. So no need for SetCPU there. I'd say Juice Defender can still come in handy with turning data off when you aren't using it.
My 2 cents. Your results may vary.

I use ultimate. I did run a night schedule, but that kind of points back to my original observation... I'd have night setup from 11pm - 7am and see a horizontal line for battery during this time (wow JD is really working)... BUT, with it uninstalled, during the same period of time 11pm - 7am my battery was also horizontal line... So did it really do anything? I'm on wifi at my house so when I'm sleeping the phone is wifi and not constantly pinging the mobile network (does that make a diff. being on wifi)?
I also did like the wifi only when home setting.
With ViperRom, I probably don't need set CPU anymore... Maybe i'll throw JD back on.
One question.. were you running the beta JD? I noticed the beta would always throw errors in the log stating i needed to uninstall, reboot, reinstall (I never did) anyone else have that happen?
These numbers sound like you have the radio off and don't turn your display on. Pretty amazing numbers otherwise. Would love to know the rom + kernal you're using
edit: I see the post above you mention viperrom. Typically if you have data turned off and display off any device will last days. My OG evo lasts for around 48 hours just sitting there. Still really impressive if you're using your phone within that 30 hours

I've never tried the beta; I started with standard, upgraded to Premium, then eventually upgraded to Ultimate (I use the 'Customize' setting, but rarely the 'Advanced' config).
I hear ya on the night-time wi-fi thing. But with this particular phone (and before I rooted and changed ROM/Kernel), on some nights I would be connected to wi-fi and get ZERO CPU sleep time, other nights it would sleep - I have no idea why. It is conceivable that if the only polling your doing is e.g., Gmail, that either it doesn't happen at night, or it happens in such a way as to not knock the phone out of sleep (it IS Google's OS after all).
On a related note, I'm using K-9 mail (my primary mail is Yahoo); it throws wake-locks all the time (set to poll every 15 minutes), but they don't seem to impact battery life or take the device out of deep sleep which is why I suggested that case above.
One other item I like about JD is the ability to permission each and every app for wireless/network access; obviously mail, calendar, phone, etc. need it, but some apps simply don't, and I've been surprised when I set it to 'notify' and some random game pops up seeking network access. Looking for an update? who knows, but I lock 'em down anyway.

I do not turn off data/radio (no airplane mode).
I'm running ViperRom 2.2 with the latest loskernal experimental.
My display was on for roughly 2 hours (again, just used it as i happened to during the course of the day) and data was on.

Interesting thing is with the latest JD build it has the bluetooth settings, so i can leave my headset paired, but the phone disconnects while not on a call and then when i get a call, it turns on... kinda cool.
In regards to the permissions... do i need to give the email applications permission for enable/screen off? (so that I'll still get the notifs?) or just enable (as in when screen on).
thanks,
RR

[Q] Juice Defender: does it work?

Hi, Ive been reading a lot about battery saving apps that I started to get curious as to whether these apps really work.
I installed JD out of curiosity and I have to say that all it doea is disable automatically your phone connections to help you save power. Things that you can actually do manually. Like turning off wifi and mobile network. If im not mistaken you can disable mobile network under your phone's settings.
So my question is, if you can do it manually, what is the point of apps like juice defender? It eats up ram and runs as a background process which in my opinion does more bad than good to your battery unless your the i dont know how to disable connections manually in my phone kind of guy.
Somebody please enlighten me. Thanks.
I have used it for a long times. Since I used Xperia PLAY.
I think this program is good. Yes, if you can manually do it. But the feature I like the most is Screen. It can change CPU ghz according to your screen on / off.
It saves my battery a lot.
Press THANKS if you agree with me.
I am a long time user of jd but these days the only feature i use regularly is to disable data overnight.
Sent from my LT26i using xda app-developers app
- Airplane mode over night
- automatic wireless connection with "location" feature (if near a known wireless network it starts the wireless and connects, if not near it directly starts 3G)
- I do not have to mess with on/off wireless/3G
- automatically syncs every hour, so I have to do nothing but still get my mails
- with rooted phone underclock on screen off
- bluetooth off after 5 mins without connected bluetooth device
etc....
It is NOT for you if you want to have online connection all the time. And it is not for you if you don't mind to do all the things manually it does for you.
And in my opinion only the full version really helps, the free version does not much...
I think it's a great app! :good:
If you just need to auto toggle data, check out 3GBattery too.
https://play.google.com/store/apps/...wyLDEsImNvbS5teXN0aXF1ZS50aHJlZWdiYXR0ZXJ5Il0.
basically, there are 2 main things that drain our devices: 1) 3g/2g and 2) display brightness. I've been using JD since ever, and the difference is awesome with and without. Even the free version is enough to save some batt, in the Agressive mode (connects every 30min).
Besides JD, I am using Greenify. Which needs root to work and does a beautiful job with background apps like Facebook, GMaps etc.
works on both my devices :good:
Personally I think this app is useless.
As OP has said, you can just set up those things manually.
This app just eats RAMs and use your battery up more.

This is illegal, if you cant buy an app dont use it.
It's a paid app
WORTH EVERY PENNY
I have automated mine to do the following
As soon as I enter my work car park, it drops the volumes, switches off WIFI
I leave my work car park, volume to max,
I enter home, WIFI on, Volume max
after 11pm - 6.30am everything on silent, wifi & data off
then when i scan my NFC tag in the car, switches on GPS, loads co pilot
re-scan tag, turns off GPS and closes co-pilot

Sounds cool
But mine is too extra complicated to share, I now have over 30
But the most i like is nightmode,
It make brightness 10/255 and opens an app screenfilter
It makes brightness extremely low and this all happens from 12am-3 am
IF YOU LIKE MY WORK, THANK ME BY THE BUTTON BELOW
Anyone knows what effect this has on battery life?
It doesnt waste battery that much, why dont.you try it and see battery stats

Was thinking the same. Any partial/wakelock issues caused by the program constantly assessing the environment. As it happens I am thinking of using the program to reduce battery drain and shutting down WiFi when out of range of home networks but if it's negated by the situation above it seems pointless for my needs.
Any one care to comment?
I've been using Tasker for a couple of years accross 4 different devices now (X10i, DHD, TF101 and GS3). I have a lot of profiles set up to do various different things and I can honestly say I've never seen a noticeable effect on battery life.
That said though I don't use the GPS location state at all. I imagine that particular state would drain battery pretty quickly. I use the WiFi Near state a lot though and, as I've said, never really noticed a detrimental drain on the battery.
I suppose it depends on what you do with it but overall IMO it's a very well written app. Extremely useful too.

Waiting for app sale. The price is slightly higher than what I'm prepared to spend, especially because there is a free alternative from Microsoft called on{X}: http://techcrunch.com/2012/06/05/onx/

Yep! This is what I was hoping to use it for too. My betterbatterystats has identified my Wifi as the one real drain on what is still a very good battery life. So although I could turn it off myself I just know I will forget to turn it back on at home and would like a program to do it for me. BUT if one negates the other it's not worth the effort.

Well your WiFi has to be on to use the WiFi Near state. You could potentially combine it with a Time state too though. Just for example you could have Tasker turn WiFi on for 1 minute once an hour to check for your network(s) then either turn off again if no network detected or connect and remain on if a network is detected... if that makes any sense!
It would save battery compared to leaving WiFi on all the time.

What effect does it have on, I have a task to turn of Wi-Fi during 10am and 1pm; but I try to turn on Wi-Fi during this period. Will it automatically turn it off again, or allow me to continue to use Wi-Fi?

It will allow you to continue to use it. That sort of profile works as a toggle based on the time state so at 10am it will turn it off - but only at 10am. If you were to turn it on again straight away it would stay on until you either turn it off manually or another profile kicks in which is set to turn it off again. The same goes for anything else such as ringer/silent/vibrate, mobile data, GPS etc.
@Greedyfly: you're welcome

You guys can try Llama...does the same thing and cost nothing....i am using it for couple of days and it is good.

Tasker can do wonders...but it requires you to be some kind of Tasker-scientist to get things done. I recently discovered Llama as well. It's free and simple but capable.
Yeah Tasker does have a reasonably steep learning curve admittedly. By no means insurmountable to most though.
I suppose it depends on what/how you want to automate. Tasker is very powerful but not so simple. Llama is free and easier to use but no so powerful.
Both are good automation solutions. Locale is another one to check out.

I've been using Tasker for the best part of a year now, awesome piece of software. Negligible impact on battery life and it's astoundingly powerful. A few examples of profiles I currently use - detects headphones/bluetooth headset and reads any text and who sent it, useful when cycling or out on the bike. Disables screen lock when at home, I use the phone as a control for my media centre so it remains unlocked at home and turns the screen on as soon as the handset is picked up, controls a variety of connection states according to location and time.
These are just scratching the surface. On top of this I've had direct dealings with the dev on a couple of occasions, genuinely nice bloke who does his damndest to solve problems as quickly as possible. All in all, this and Titanium backup are by far the two most useful pieces of software I've bought:good:
