Improve Battery life with automated tasking!

I have struggled with horrible battery life. I tried everything from roms, radios, setcpu, registry tweaks, all builds on this site and still couldnt pull much more out of my battery.
I ran across an app yesterday while digging through some articles looking for a battery miracle and found an app on the market called tasker. It is an automated tasking app that allows you to set different variations for anything you could imagine on your phone.
I have only scratched the surface with what it can do. The link below has a simple GPS setup to get started.
It enables you to turn on a certain function (WIFI, GPS, Bluetooth) when you open an app and then allows you to close it once the app closes. No more forgetting to use the power control widget!
Hopefully this thread can evolve with suggestions and other setups to help save more battery!
Today I was able to get 13 heavy usage hours out of my phone. Before this I was in the neighborhood of 8-10 depending on usage.
Any suggestions or new scenarios appreciated.
Hope this helps!

Thank you for sharing. This app is AMAZING!!!! (I didn't really get it for battery life, my life is already great, but it's so handy for everything and has so many options!)

Does Tasker support turning on/off 3G? I.E. could I set it to turn off 3G ad drop to EDGE when the screen is off, thus saving battery?

yeah.. it works awesome.. so many settings to config up.. endless combinations lol..

good stuff dude!

Yes, you can set it to turn off everything when you turn the sreen off.
To do this go into tasker
Add new
Click Event
Click Display
Click Display off
Click Done
Click Plus sign in bottom left corner
Tap Net
Tap Mobile Data with the gear beside it
So the same thing but in reverse for Display on!
Along with this you can set a time profile to check turn on data every X minutes to grab your emails
New Time
00:00 to 23:59
repeat every x mins
add task mobile data on
It dues shut off APN completely however, I dont think there is a way, yet, to just shut off 3g. If anyone know a way please add it.
Hope this Help!

Looking for help with a profile
Need some help from the community.
I am trying to set up a profile that will work as follows:
Screen off > Kill all tasks using ATK
If I choose it as an app it loads the app but doesn't kill anything. This would be a great battery saver.
Anyone?

This looks like an excellent app.
Just a quick question (I've only ever installed free apps from the market )
If I pay for this app and validate/register it online using a Desire based android build, but then subsequently load a different build (maybe a nexus based one) will the app still install and work correctly?
Or will the app be seen as being transferred to another phone and refuse to work?
Thanks for any advice

Guys,
Please don't post warez or links to warez (see XDA rules).
Thanks

Battery drain - source found

I have had problems with battery drain on my S2 from the day I bought it. The battery would last apprx 12-14 hours before going dead - almost without use.
I then removed an Exchange (ActiveSync) mail account. And the problem was gone. 30+ hours battery with no problems. I added the mail account back, and the problem reoccured. I testet this some more times and it was consistent each time. BTW I was not using push, just manual mail update.
The mail account that I am adding forces encryption on the phone, so it might be that this is the actual source of the battery drain. But it shows that the phone is useless using ActiveSync with encryption.
I was hoping that this was fixed in 2.3.4, but the problem was the same there as well. Until this is fixed (which I don't suspect will happen) I can not use the phone with my job email account because of this.

Yes you can go to themes and apps section and search for the administration removed email app, stock app with the corporate control removed try it and see if that works better, currently using it myself and no big battery drains.

Where is this? Android Market? I did not find it...

Using 'Push' uses a lot of battery. See if you can manage with 'Manual' or scheduled to check every few minutes.
Also disable 'Auto-sync' if not required.

As I said in my initial post - I do not use push - I have everything on manual. It drains battery even if I do not check the mail once.

jr866gooner: I found it, but I guess this forces rooting of the phone? It is a phone owned by my employeer, so this is unfortunately not an option :-(

You can unroot upon return just use a insecure kernel which will bypass superuser I think.

I also pinned down my huge battery drain (10% per hour) to the Exchange email connection I use. I have tried various stock ROMs and some custom ones, but all seem to give the same result. I must say that older ROMs did not seem to have the drain this much. I am currently running Cognition 1.5.1.
Currently I work around the drain by manually syncing my email whenever I want to read email and this results in a whole lot less battery consumption (I now have 50-70% battery left with moderate use, instead of only barely managing 8 hours or so.
I have installed the modified Email.apk to see if this fixes some issues. The email.apk in Cognition did not have a .odex file anymore and was a few bytes different in size, so I really really hope that this fixes the drain. I'll keep you posted.

Would someone please be so kind to link the thread with the modified apk? Forum search through tapatalk is not always an easy task
Thanks a lot guys

You can try the stock asop one from dark knight thread, think check fixed the wakelock issues, very similar to the Samsung version minus a number of features but based on the same source.

My test results with the email.apk I had found did not really show improvement of battery usage, so I am very curious for the link that nikzDHD means. Is this the one patpeewee mentions? I did not see any remarks about wake lock issues in the op.

Hello to everyone.
I know that there are some similar threads in this forum, but no one is strictly related to the CM9 alpha IML74K.
I know as well that this could be part of the CM9 user discussion thread, but I'd like to share the best settings to get a good battery life with our S2 in a clean thread.

Data on all the day. I turn it off when I go to bed.
Wireless on when I'm home and need to use dropbox or download a big file from my Gmail account.
I'm using CM9 01062012 (I know, there's a new one, but I've reached a very stable daily rom, no FC, no random reboots, fast and smooth).
Modem XXKL1
Now my battery lasts two days.
Well, when my girlfriend tells me stories about her life, it lasts one day and a half.
Important:
I've uninstalled Facebook app which was causing a battery drain. I'm using the mobile web page instead and I've to tell that it is faster.
Other apps installed:
Twitter, Maps, Sygic, Whattsapp, Beatiful widgets (with manual weather update), Xda premium, ...
2012-01-14 Added CyanogenMod Settings Apk v1.0 (from SGS forums)

NEKD5 Modem Zip package.
Flash from recovery. Follow cmsettings instructions.

Nice post. Going to try some your suggestions.
I'm sure loads of other xdaers are going find this useful too.
So many posts in the cm9 discussion thread about battery life and how to achieve optimum performance good to have a thread about it.
Big props

Apparently its a bug. It makes the OS look like its working over time but actually it won't be. Its somewhere in the cm discussion thread if you want to see the posts about it. As far as aware its not fixed yet with any of the builds.

The same here. But I've noticed that using Fastreboot app, it seems to kill/restart stuck apps/processes.
Anyway, rebooting the system before the night helps a lot.
Unless you're not a modern vampire...

Agree with others - excellent thread. There seem to be so many battery challenges with CM9 that a separate thread will lessen clutter in the discussion thread.
I've tried a number of your settings and have also flashed the KL1 modem. I had high hopes for KP4 at first, but it seems to have slipped back into old habits!

The app and the process are still running after you close them.
I have tried to logout, but it's still there. I think the process keeps going for notifications and photo uploading.
I've tried to kill it, but it comes back after few seconds.
Finally I gave up and used the mobile web page.

But that isn't related to CM9, i had the same issues on gingerbread.

Yes, sir.
I knew it.
But it seems to me that Facebook app is eating more battery on ICS.
Checked my battery info and found out FB app percentage was 15% in 6 hours and I've used it just to read few messages. Then I've logged out.
I could be wrong, but I think it needs an update to control battery drain.

Indeed. I'll bet there are a host of apps that will need subtle tweaks and optimisations for ICS. Another reason not to expect too much from CM9 in terms of performance as yet...although access to kernal sources is obviously the big one!

CM settings
Trying right now CyanogenMod Settings app.
Flashable zip from recovery. The apk goes to /system.
It comes from GTi9000 forum and as I can see, it works perfectly on my S2.
It doesn't have so many options, but few are very important.
Let's have a look...

I'd be very interested on your feedback on this app.
On a different subject, I seem to have my battery back behaving reasonably well again with KP1 modem. In my tons of testing it seems like Nova Launcher - as much as I like it - is a significant contributor to my battery drain issues.
This could be because I have installed a bunch more stuff on Nova than I have with Trebuchet, so my next tactic is to gradually reintroduce some of my favourite widgets to Trebuchet to see if one of them suddenly starts killing my battery.
On the down side it may mean that I can't use one of my widgets for a while but on the plus side it may eliminate Nova as a battery drain meaning that I can go back to using it.

Have you tried FBM for facebook?
Basically the same look as the facebook app. But supposedly a lot cleaner!

As I said before, don't expect a very useful app. It's the 1.0 version, and hopefully it will be a great app. But for now I've tried only some settings in the automatic backlight and modified the notification power widget.
At the moment, that's all we have. Anyway, give it a try, if you'd like.
Screenshots added in the first post.

Anyone able to disable button's backlight? Its still on even though i set it to "0" in the custom settings..
Another thing,is it possible to the haptic feedback tweaks like in cm7 settings?

Back from some modem testings, I'd like to say that NEKD5 has surprised me.
Never loosing data at all, best battery life and no problem with sms and sync.

[Q] Facebook/Linked in... APK or WEB?

Hi all,
So here is my question...
I've been having horrible battery drain and have not yet put my finger on what is causing it.
I'm thinking it could be facebook/linkedin/other apps on my phone.
Is there any reason to install the APK version when a mobile web version exists?
I see the web version being a good choice as it won't be an app installed but rather just visiting a web page.
Any thoughts?

get better battery stats and that should let you see whats causing the drain....or look in settings>battery and see whats running there as well. the apk is there for convieniance and thats about it. the constant updates and radios being on will kill your battery cause the phone is consistently looking for new information. its really all user preference but to me bookmarking the site is just as simple as having the app. you just may not get the update that your friend you dont talk to is eating a taco and taco bell as fast.

It appears greenofy does a lot of what autostarts does. I use autostarts for all apps and disable most everything (for instance facebook with an app is installed/uninstalled etc).
Having said that, after wiping my phone yesterday and doing a fresh install of TriForce 3.1 with Agat 5.1 I've noticied a significant INCREASE in up time.
I only installed a few normal google apps. Linkedin/Facebook I'm using the web version. I got 21 hours out of my S4 with 2 hours of screen on.
When I have my phone configured "normal" i've got close to 90 apps installed.
I'm going to run a "bone stock" from for a few more days to see how the battery life is (i know you have to give the kernal a few days to burn in).
I just wish my phone could last a lot longer before dying.

try ktoonz kernel.......they have alot of preset kernel settings to help you get the most out of your battery and still maintain performance in the ktoonz store. i normally run 1 day+ with around 3 hrs 45mins screen time......and my screen time is usually gaming (psp emulation)and tweaking differant settings or downloading movies music etc.... so its pretty heavy usage...

After such a long wait, what are your thoughts on the lollipop update?

I concur

Battery life seems to be sucking!
Gonna reformat my sdcard & then put my media on it & see if that helps before having to do a factory reset.. used to get 2-2.5 days our of a charge now this battery prediction add-on is saying 10 hours left on a battery I just put in an hour ago. Completely stock & not rooted, so backups are a pain & Helium apparently isn't 100% so that option seems pointless. Suggestions?

Not sure yet -
I haven't noticed any issues with Maps. I kinda like the new swipe on the lock screen to swipe to the phone dialer. I don't like taking away the audio controls on the power button screen. Love the fast camera focus (didn't know about that till I read this thread).

For whatever reason I can't seem to find the trusted devices thing for my FitBit...
EDIT:
Scratch that. Gotta enable SmartLock in the security settings.

Do you guys recommend a complete reset?

My most wanted feature was the combined security lock screen (Finger lock, PIN, etc) and I can't seem to find a way to enable it here.

I don't like the new lock screen notifications now. I don't need to see my BT devices and Ultimate Rotation Control on my lock screen. I'm fine with the missed calls, texts and emails but not with the others taking up unnecessary screen space.
Anyone know how to get them to show back up in the notification bar up top?

I like the camera, UI changes, look, etc. Overall system seems quicker. I have not had any issues so far but it has been less than 1 day of usage. I did notice the battery discharged quickly at first, however it seems that the battery drain is leveling off after a while.

I always used the stock messenger app. I really don't like all the orange. I'm trying alternatives now. So far textra is nice with black background

Calls don't work with android auto.

You guys tried benchmarks? Look antutu, is extremely low!! :/
