I have searched the market and google, but I can't find anything that will work with my specific scenarios. I want a rules based app, if it exists, to activate gps when certain programs are launched, like Navi, or maps, etc. Then, the biggest reason I want it, is because I would like it to deactivate on close. I have a real bad problem of remembering to kill it when I am finished using it, so I end up killing the battery prematurely because of my own stupidity. I've tried my phone my rules, and two or three others, but I couldn't figure out how to set it up to do what I wanted. Maybe I'm just an idiot. who knows. Thanks for any advice.

Cyanogen has profiles like that, but I don't think it extends to GPS.
I've pretty much always run sense ROMs and I ALWAYS leave my GPS checked on. It only uses it when I'm using an app that needs it. I'm not sure where the idea came from that if GPS is left on it will use it all the time, but I've never seen evidence that is how it behaves. Unless AOSP is weird and does try to lock all the time or something....
I use Easy Profiles and like it a lot. It takes a little work to understand but is very useful and really helps me save my battery.
As the previous poster says, most apps turn off GPS when they are deactivated.

Stock rom and I leave my GPS on 100% of the time.
I get from 12 hours to well over 24 hours of battery depending on how I use the phone. The GPS power turns off if no software is hitting it for a location.
Turning off the GPS (or WiFi for that matter) has never changed my battery life.
Maybe I'm mistaken then. It just seemed like my battery died off quicker after using Navi. But I didn't actually do anything to verify this. I will also try easy profile as one poster suggested.

I'd suggest before adding another app that will CERTAINLY eat more battery, to take look at what apps ore services are eating power, and exactly how they're doing that. Even the basic battery stats displayed in stock Android will give you a rough idea. Something like JuicePlotter will highlight what and when certain basic functions eat power. If you're GPS is running, it will stick out as a different color blur coming off the power plot line.
I'm a strong proponent of power management through strategy, not brute force of apps managing it. Kinda like a bank with a good security system... it makes more sense to design the building well, rather than hire guards/apps to do the job at a higher cost in dollars/watthours.
I use Battery widget to monitor my juice usage, but it just "seemed" like my battery usage was worse with GPS on. But I don't use my phone in the same way any two days in a row, so it was probably just in my imagination.

If GPS is constantly on being used to update traffic, geotag photos, or track you on GPS, you're going to usually notice sharp drops in battery life. I use the battery widget too, but JuicePlotter can better illustrate where the power is going.
I'm a little surprised noone suggested Tasker, Locale, or SettingProfiles since they will all do exactly what the OP wanted and more. Tasker isn't as user-friendly as the others but seems to provide more functionality. I currently have it set just as the OP wanted. Turns gps on when Maps, Nav, etc open then turn it back off on close. Probably unnecessary but doesn't cause any problems for me so it's fine.
thanks A0. I will definitely check that out, as I think it will work for the other things I wanted to try too.

I have a Holux GPSlim 236 bluetooth GPS receiver that I want to use with my GS2 when I go mountain biking instead of the internal GPS as that would drain the battery too quickly.
I've successfully paired the receiver with the GS2 but none of the apps (Tracker, GPS Test, Maps, etc) actually "see" the external gps receiver and just display no lock and don't show any satellites. Switching on the internal gps receiver makes everything work as expected.
Is there anything special I need to do with the external receiver and pairing it to the GS2? Is there a setting buried in Android somewhere that directs all GPS apps to use an external receiver? On the old WM6 platform you could choose different com ports for the receiver but I see no options in android for that.
Never mind. It appears you need an app (yet again!) to do this. I installed blue4droid and it works now. Why isn't this functionality part of the core Android OS?

Very few people ask for this feature (first time I've seen a request). Your need is very specific, are you sure you will save much battery with a BT-link constantly running?
Older platforms like Symbian S60 and WMP6 supports this quite obviously since this was the only way to get GPS on many older smartphones, but on Android almost all phones have GPS from the beginning.
This seems like good example to me where a dedicated app is better than making the standard Android OS more complicated.
Please remember that more or less every app in the market fulfills purpose for a certain number of people, that doesn't mean that all these apps should be included in the OS...
I hear what you're saying but I'd be surprised if BT used as much battery as the GPS. I took the GS2 out for a test yesterday on a short 1.5 hour mountain bike ride with the internal GPS on and it drained 50% of my battery. A lot of my rides are usually a lot longer in the 4-5 hour range so the battery will never last.
I assume BT will use a lot less power but I have yet to test it which I'll be doing in the next few days.
As for it not being a common feature request, I guess that you are right when taking into account all the Android devices around but it's actually quite commonly asked for in the cycling and running world where you want to track your path and other parameters during your training. the phone batteries just cannot cope with powering the internal GPS for more than a few hours.
I don't mind using some apps to enhance the OS but I just feel with Android it seems expected that you need to bolt apps on to achieve what normally is basic functionality. Also a lot of the apps require permissions to parts of the phone that have nothing to do with the functions the app is providing. I'll concede that perhaps in this case an app would is suitable than having the functionality in the core OS.

50% in 1.5h sounds a lot.
I don't think this is because of the GPS, what app do you use to log the position? Does it keep the display on all the time?
I haven't checked battery when I've been logging that careful because it hasn't been a problem, but I can see that I have a 3.5 hours log in my track-list and I remember that I checked the map a lot as well during that hike. I'm pretty sure I wasn't close to draining the battery.
Modern GPS-chip doesn't use that much battery, people are overexaggerating the drain from GPS-chip, probaly because of problems with older chip designs. But a lot of software that uses GPS, e g car navigation system are often huge battery hogs though.
I've read that this is the chip inside SGS2:
http://www.csr.com/products/25/sirfstariv-gsd4t
It seems to use 8mW with 1hz update. So the battery in SGS2 can run only the GPS chip for (4V*1650mAh)/8 = 825hours...
So I believe the battery problem you have is caused by something else, so adding an external GPS might not solve anything at all.
Hmm, that throws a different light on it. I'm using Run.GPS for my tracks. I'll have to monitor this more closely and try a different app for comparison. What did you use for tracking your hike?
The app isn't keeping the screen on and I physically turn it off with the power button anyway. The app is also set not to illuminate the screen back light although I don't think it makes any difference with the AMOLED screen.
I'll try a comparison with the external GPS and see how much difference there is to try establish if the app is at fault. I expect tracking using the external GPS to use significantly less battery so if battery drain is still high then it points most likely to being the app at fault - we'll see.
Is there any app that can list the various apps / processes that are running and show how much cpu is being used? I want to see how much cpu power the tracking software is consuming.

I'm using my "tracks", it is an pretty good (but simple) app, but it does not do any GPS filtering, så especially data like max speed tend to be incorrect.
There are definately app's to check processes, but I don't know which is the best, I believe System Tuner Pro is good:
https://market.android.com/details?id=ccc71.pmw.pro&feature=search_result
I tried Tracker but preferred a more cycling specific app.
Thanks I'll look at that System Tuner app.
So i love the evo 3d its great, but.. i dont even use it much and the battery is dead half way through the day. I bought a extra 2 battery and a external charger and just charge the other battery while use one and then switch when it gets to 5%. The replacement battery actually runs cooler than original. (according to battery monitor app) replacement runs at around 80F and original 90-100F
Im really a android newb and dont even know how to calibrate the touch screen (maybe there isnt evne a place to do it) im used to windows phones. Is there some tweaks to get more use out of the battery? also the battery says 93% when it finishes charging on the external. I guess it gets to 100 then starts to drain?
Sorry for my english and ranting. Thanks in advance
Have you rooted your phone? If not, you could try juice defender. It manages different things about your phone like data and what not. If you root it, then I suggest getting netarchys kernel. I'm using empiires beta ROM with netatchys kernel and my battery has lasted 20hrs (I haven't used it too much though. Just for XDA and text messaging)

Yep that's exactly how I use my phone for the most part. Its pretty good for a beta. Its suppose to be as AOSP as possible and sense is almost completely removed. Only problems I've had is that you can't change the ringtone or print from the default printer. And you can't view 3d pics because he has the AOSP gallery instead of the HTC one. And you can't get to the gallery from the camera app. I'm not a big picture taker though

Also check and see how many different things you have running in Sprint Zone, more than likely you will have everything turned on in settings. You need one up though, so I normally leave help on.

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 (everyone, for now):
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 3D's updated Sense 3.0 allows users to access these radios and other settings from the notification pulldown menu, , under the "Quick Settings" tab. 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.
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.
Menu>Settings>Display>Screen Timeout
I use 30 seconds.
6. 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.
7. 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.
-This is done by hitting menu>settings>monitoring enabled. Then after some time has passed, ht menu>monitoring>history>change tab to top apps, and see if anything is above, say, 2-4%.
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.
Root Tips LIVE
Tips for Rooted users:
1. Try out custom kernels.
By going to the EVO 3D 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 0-2 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 2-5 of screen on
* *Heavy usage – LOTS of video watching and games, 3D pics or video, 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. 5+ hours
*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!

Juice Defender and Advanced task killer for AT&T SGS2, do they work?
I found that Juice Defender helped, but it also annoyed me as it is able to save battery life by disabling WiFi/data connections while the screen is off--and then took a few seconds to actually reconnect when you turned it on. Some may not mind this, but it bothered me.
As for task killer, I've only read that they do more harm than good, so never tried it.
Don't waste your time with those crap applications.....they are made to manipulate background running apps while they themselves ARE apps that run in the background.....killing processes that only restart themselves if need be....and are then killed again. Smartphones are not dumb. They do not need someone to tell them what they need to function well. If you need to save battery....shut off background data while you're out. Turn down screen brightness.....these are 2 little things that your phone leaves you in control of. Installing apps that control wifi sleep policy? Your phones OS has that built in set in the the wifi settings. Don't be duped by some "placebo" app. You have a awesome phone it don't need some 2 dollar app telling it what to do.

Advanced task killer wastes battery, the LINUX kernel is pretty good at managing the ram as it is. Thus atk is constantly running wasting battery, usually killing apps that don't need to be killed, in many cases apps that are expected by the os to be ready to respond to you when use your phone.
I don't know how many times I have seen someone complain that "my phone is laggy, my battery life sucks and ever time I look at atk it its killing more apps and clearing ram all over again."
I always want to say no duh!
The only thing a task killer is good for is killing a rogue app. Using one to run constantly in the background as a secondary ram manager is completely counter productive.
Sent from my SAMSUNG-SGH-I777 using XDA App
Like the others said above, atk is bad for your phone. It kills off processes that might just restart themselves, thus using up power (to remove them, then to restart them). Your phone's memory uses up the same amount of power whether it is empty or full. You might as well leave the memory full so that your phone can possibly respond faster to your requests. Android will manage your memory efficiently for you.
As for juice defender, I love it. I get about 50% more power without having to micro-manage my phone. I leave wifi and Bluetooth on, and JD turns them on and off as needed. It can overclock and underclock as needed, etc. However, if you're going to get an app, look into Tasker. That app will change your configurations depending on you're location. arrived to work? Sounds off, wifi off. At the gym? Wifi off, volume to max, Bluetooth on. It's very configurable.
I have used both. I only use ATKiller for apps I pretty much never use. As for Juice Defender (I have Ultimate) It works great for saving battery as it says, but like stated above, it does shut off all wifi and data connections and other things so it takes a moment for them to all start up when you need co0nnection. But if you're like I am where alot of the time the phone sits dormant during work hours its no big deal to have things shut off. Better to save battery for when you are going to use the phone IMO. So I like it.

i just didnt like that I was getting notifications late because the data was off. Maybe its only for 5 minutes but its still late and I didnt like that. I'd rather use a charger and keep my battery at a good level.
For me, the trade off of late notifications for marginally better battery wasn't enough. it didnt save on my battery life as much as I would hope for. I didnt think JD was worth it.
but thats just my opinion
I've never used Juice Defender - I think a few people had it cause drain problems on the Infuse.
ATK is useful for nuking apps that are holding wakelocks for way too long. People keep on ranting, "ATK is useless, Gingerbread has good RAM management" while completely ignoring the issue of wakelocks.
ATK is not a background process - when you use it, it kills itself by default after killing everything else.
Note: I don't use the autokiller features. I manually kill apps that seem to be eating data/wakelocking the device. I also nuke anything that I'm not planning on using any time soon to avoid any wakeups from those apps.
Back in early 2011, ATK was a required app for any Facebook user, due to Facebook holding extremely long-term partial wakelocks.
Bad news is that the current #1 battery drainer app is a "zombie app" that keeps coming back after killing it (Skype).

As covered in another thread, Skype is one of the most common root causes of the "Android OS" "bug".
(In general, the AOS "bug" is not a bug in the phone - but the nature of suspend/resume on this phone is such that battery usage due to an app using data too often gets blamed on the OS.)
hey, so i have ran pretty much every "jelly bean" rom out there for this phone for about 2-2.5 months. maybe less. note sure..
anyway, the battery has been horrible! on every rom.. I have a 2700 mAMP battery, and a regular Samsung battery. I have to use both once a day for this phone.. now I have no idea what is making the phone loose percentage after percentage of battery as fast as it has for me, but everytime i post i get about 0 luck from people that either have the same issue, or just people saying they have heard it a million times. i probably should have put this in the "Q&A" thread, but maybe i forgot. can someone, preferably more than one, help me out here?? i don't get how other people say they have 8 or more hours of screen on time with half the battery left. it just doesn't make since. I am loving the android system. but this could be anything! the apps in the background. the kernel, maybe I didn't clean my cache or something. i can't raise my brightness up to far or it'll drain my battery, jamie in the paranoid thread said he had his batter on 100 percent and had excellent battery. so I'm far from confused here. do I need to get another phone, or what. very much apprentice the help from as many people as possible. I love my phone, but I hate that i have to focus on using two battery a day with this phone.
Same here battery draining pretty quick on all jb ROMs.
Sent from the TermiNOTEr!
Battery usage is highly subjective..
It's nearly impossible to determine a baseline Usage expectancy, simply due to the untold number of variables that drain the battery.
We know the obvious power users ....the display, wifi, data ..
But it gets far more difficult to track the Usage after that.
We know that JB is not optimized for our device, but it's getting better, and until we see a true JB kernel with the rom matched to it, the battery is going to suffer.
Then of course we have the many services that users run, along with countless apps ...
Long story short ....maybe a more stable choice would work better? ?
Like ICS, At least until JB calms down a bit ...
I'm actually running Saurom as I type this ...and my battery life is excellent.
JB just isn't quite there yet ...IMHO ....g
to get better battery turn brightness to lowest usable setting, turn off sync for any non essential apps, turn off soft key lights, flash a kernel that lets you under volt and under clock, try different govonors and io schedulers, turn off gps, put in airplane mode when not using. these should help. keep in mind cell signal strength will also impact battery and 4g will kill it faster then 3g. i am on cm9 stable under clocked to 1.18 undervolt all by 25mv( not much change but i like to be safe) ondemand and sio and get amazing battery life.
What's your screen-on time? 4 hours is the close to the limit on ANY rom for our Notes. You have to make sure it's not some sort of confirmation bias going on here.

It's nearly impossible to determine a baseline Usage expectancy, simply due to the untold number of variables that drain the battery.

thank you so much man! i actually went to at&t and they mentioned that too. they said the kernel im using isn't fully optimized for the phone yet. other words. the phone wont support it. he said basic stock ics is the best thing to do now. he also said. these forums are for phones from Europe as well. not just for AT&T in the us. again, the ROMS these devs are making are not supported for the phone, and is kinda like a mimic of something its not. he said jelly bean was out, but i don't know where to get it. can someone tell me how to install ICS, because when I download it, and use KIES, it installs the system, but never fully completes the process.

Sure...
At the top of the general note section, you will find the "note super everything thread"....
Scroll down to find the ICS info you need...
There are many great ICS roms, and you will find that your phone is "MUCH" better running on the software that was intended for it..
Do the homework in the superthread, and read, read, read......then if you have more questions....just PM me, and we'll get ya up and running....g

thank you so much! I will get right to this
I never got more then 2 hours screen on time on any ROM, just figured that was normal.
Ugh.
That is low scout ....
I pull 3 hours average ...
Must be the internut ..on XDA ....LOL ......g

I'm in the same boat as manel, never gotten anywhere above 2h on screen time. Maybe additional 10m or so. Figured it was normal lol

Battery life is purely subjective. No two people will have the same experience.
Have you used an app like CPU spy to make sure the phone is going into deep sleep? Rogue apps keeping the phone in a wake lock can seriously affect battery life, but its hard to say if anybody's apps are doing that, because we all use different apps and there's no list of apps that keep a wake lock, so you need to use something like CPU spy to see if you are going to deep sleep when your screen is off.
Related to apps as well, don't use any task killers or constantly kill apps when you exit them. A lot of people think killing apps is necessary when it completely is not. Android, since donut or eclair, manages its RAM very well, so that when a properly written app (ie. It's not keeping a wake lock) is in RAM, it's just in a frozen state not using any CPU cycles. Constantly killing well written apps hurts battery life, because restarting the app fresh is much more processor intensive than pulling a frozen app out of RAM. Plus you don't have to deal with annoying loading/splash screens.
Also, like others have said, using the lowest brightness possible, and turning off sync for any unnecessary apps will help battery life. GPS doesn't matter so long as you don't keep something running that uses it. If an app isn't using GPS, then GPS isn't using battery. I always leave my GPS on and do not notice a difference compared to turning it off. If you're paranoid about GPS leave it off, but it's annoying to have to turn it on every time you want to use an app that requires it. You can also disable location access in most apps like Facebook, twitter, etc where you don't need GPS really, and that will make leaving it on even better. If you don't use GPS much anyways, leave it off.
Like somebody said, your cell signal can greatly affect your performance, so use WiFi whenever possible, and even put a data toggle in your pulldown so you can disable cell data when you don't really need it. WiFi in general uses less battery than cellular data, so I use it whenever possible.
I've also noticed that how you use your screen on time also has a great effect on battery life. When I have extended lengths of constant screen on time where the phone starts heating up and whatnot, I see much less battery life than if I just use my phone here and there intermittently. Long stretches of screen on time stress the processor and battery heating them up and making them less efficient, where as short stretches allow the processor time to stay at a cooler, more efficient temperature. If you game at all on your phone, you've definitely experienced this, as you know that your phone heats up due to the extended lengths of screen on time and heavy processor usage. Gaming is a no-no if you're striving for better battery life.
With following those guidelines, my Note sees about 3.5 screen on time with JB on Gubment Cheeze. I would get around that on ICS as well, and I don't remember what it was on GB. Fellow testers and teammates for Gubment Cheeze have seen up to 4 hours and a little more even on JB, so it's definitely possible to have decent battery life on JB.
It really comes down to your own personal usage.

I was not aware of this info....many thanks for the heads up...I always supposed that since the ram was consumed with applications, that those apps were pulling CPU usage from the device...
that is clearly not the case......g
Yep, no problem. If you go back to a touchwiz based ROM and go into the stock task manager, it shows you what's taking up RAM, as well as the CPU usage of each thing in the list. If the apps are working properly, pretty much everything will show very little to 0% CPU usage, and ones that are using it heavily will even be highlighted in yellow or red depending on their CPU usage %age. Unfortunately aosp based ROMs don't have that task manager, one of the things I miss from touchwiz.
Every time a non-techy friend buys a new android, it seems the overly aggressive sales rep that sold the phone to them 'helped' them get to know the phone and installed a task killer, specifically advanced task killer. I always just uninstall it without telling them and see how long it takes them to notice lol.
It's still useful in certain instances, for example if you have an app that doesn't run well but you still like/need to use, but in general practice android does a much better job of managing itself. Besides, if you have an app that you know runs poorly and hogs your processor in the background, but you still need to use it, with most aosp based ROMs you can set your phone so that long pressing the back button kills the current app, essentially making task killers useless.

That's a very big heads up. Thanks. But thing is when I have wifi on. Don't I need to be connected to wifi network first before it actually can help me??

This is true. What kind of signal strength do you get where you are at? Does your phone bounce back and forth to lte. I have noticed when i go from a strong signal to weaker signals or band switching a lot, my battery drains rapidly.
Use cpuspy, as mentioned, to verify you do see deep sleep. Also, i find if rooted, that seting the min speed to 192 helps quite a bit.
I never used to mess with things like Llama because of my worry about battery life with previous phones. Now that I have the note, I don't really worry about it anymore. So, with that being said...
Just thought I would throw this out there, that I am enjoying Llama quite a bit. The premise is that you create location profiles - so when you are at home between 7am and 11pm, sound is full volume, etc. From 11pm to 7am, phone is on silent (except for contacts you put on the 'noisy contact' list). When you are at work, you can have a separate profile.
It uses cell towers to determine whether you are at work, home, or wherever else, which is supposed to use less battery than GPS. Even if it does use battery, with the note II battery life, I can't tell a difference at all . Granted, there are some downsides - it is not super-accurate on location. My work cell tower has me until a decent ways off the work campus. But overall it is good enough for what I need it for.
Does anybody here use it? I was also going to try out tasker, but it's a paid app and looks like it requires a decent bit of effort. It supposedly will do pretty much anything though.
does it give you the option to use GPS to assist with location? Seems it could work similarly to a weather app, only triggering gps for a few seconds every 10 or 15 minutes to determine location.
Yup, it does allow GPS in the experimental settings. Not sure if it constantly pulls GPS or only in intervals.
People use llama to save battery, but it drained mine (I've tried it on a few phones, the RAZR Maxx was was the last one I tried). One thing I'm excited about is tectiles, same effect without a drain on the battery.
