"8. Frequently use the native task manager to free memory.. Long press on the big button to access task manager."
This is wrong advice. This actually increases battery use. The frequently used applications stay in memory so that they will not be loaded again when needed. If you purge the memory like you recommend, these apps will have to be reloaded every time, which significantly increases battery usage.

It's not wasting memory, it's just sitting there doing nothing in case you launch it soon again. If that memory is needed by another program, Android releases it immediately.
Try this yourself. Launch a game, then exit. You'll see the game still in memory. Then launch other apps and games. You'll see that the first game is no longer in memory, because Android saw that that part of the memory is needed elsewhere. It's all automatic and it works well. There's no need to fiddle with it. As I said, fiddling with it actually increases battery usage, because frequently used apps have to be reloaded every single time, instead of being called back from memory.

I have to disagree with this. Quite often I have noticed that after playing some game my battery still keeps draining like hell.
I know that Android is SUPPOSED to work as you said it would, but there are quite a lot of rogue apps which don't behave like that.
So unless you are 100% sure that your apps are not rogue apps in any possible situation I also have to suggest to use the "kill all" once in a while.
I don't do it often, maybe twice a day but it helps.

I have done most of the things you mentioned, but my battery is still appalling. I am using VillainROM 1.4, KF2. I really want to fix this, I heard some people are struggling to get 12 hours from their phone, I am one of those.

I agree, yesterday I barely used my phone. 1 hour and 40 minutes of screen on time, 3G, Sync, Whatsapping most of the time that I used it, wifi, too. Downloaded a few apps maybe 10 minutes of games. It was at 40% when I went to bed 15 hours later. I barely touched it! LOL.
I don't mind though, this is a FANTASTIC phone. I wouldn't change it for any other phone at the moment. I will probably get an extended battery case from Samsung in the near future. It's a case AND a battery ALL IN ONE! Woopie! lol.

I am starting to believe that it is a hardware fault..If lucky it could be because of the battery. You could try to order another battery and see how it goes.
If not so lucky then its something else in the phone which is almost impossible to fix at home.

I have no personal problem with you, but if you open up a thread for newcomers, you shouldn't give misleading information. Thinking task killers improve battery is a telltale sign of noobness.

My simple solution. Buy juice defender ultimate. Its cheap only less than 9 dollars. Set it to extreme and configure each app. Then go to market and search 'gothic'. Select the darkest and most plain black wallpaper. You are done! I am getting 2 days on stock rom with this setup. With about 20% of the time surfing the net via HSDPA or 3g.

I'd have to agree. Task killers are generally a bad idea.
Sure, there are poorly coded apps that stay in memory and use up CPU cycles. Those are apps that needs to be closed via task killers. But is that really the solution?
What you should do is NOT use such apps. If you do continue to use those apps, you're just supporting the developer for his poor coding. In that case, you're on your own.
OP: Try not to get too antagonistic. This is after all, a discussion forum.
Here's an analogy just for fun....
General consensus: You don't need a case for your phone.
Argument: You do need a case for your phone because SOME phones have antennae issues and a case will alleviate those issues.
Weird solution: Buy those phones wtih antennae issues and then also buy a case.
Real solution: Don't buy those phones with antennae issues! (wink wink)

+1 to this, task manager was a good idea in the old days (eclair & froyo), but gingerbread does a great job in memory management, there is no need for "task management kill" everytime you exit. Although I am a bit conservative on "frequently killing apps in gingerbread will actually decrease your battery life", but certainly, doing so will not improve it.
Using the 'Clear Memory' feature in Task Manager will stop and kill everything. Some widgets, apps will stop work. So that feature is extremely kiddish imo.
But using ATK won't do it as it has an Ignore list, if its set up properly then its the best.

With all gripes over battery life, I thought it would be a good idea to create a list of steps for newcomers that will help make battery life better.
With these steps I am getting well over 24 hours.
Feel free to add some and I will update the OP.
1. Flash a rom.. I'm using Lightening Rom 2.0 with KG1
2. Flash a kernel.. I use Chainfires KG1
3. Use Titanium backup to freeze any crap you dont need. There is a guide on here already about this.
4. Disable fast dormancy.. *#*#9900#*#*
5. Wifi Sleep Policy set this to Screen Off.. Settings>Wireless & Networks>WiFi Networks>Menu>Advanced>WiFi Sleep Policy
6. Manage your radios.. Use the power widget to turn off BlueTooth,WiFi, GPS, even 3G when not needed.
7. Screen brightness.. Set this as low as you can whilst still being readable.
8. Frequently use the native task manager to free memory.. Long press on the big button to access task manager.
9. Monitor what apps are using battery.. Menu>Settings>About Phone>Battery Usage
10. Use a static wallpaper.. Live wallpapers are nice but draw more power than a still image. Dark backgrounds are best.
11. Full overnight charge with phone off.. I found this makes a difference.
12. Change the frequency at which your mail and widgets update. Instead of 30 minutes or whatever try 1 hour.
13. Turn off AutoSync when not needed. Menu>Settings>Accounts &Sync. Note.. This will do what it says and stop any app or widget syncing though..

I'll only comment on the points I can share my opinion with:
4. didn't change a damn thing for me regarding the battery, it just made switching betweens 3g and H slower.
5. will try that, but won't it turn wifi off when the screen is off thus disabling any sync via wifi when screen is off?
6. common sense not to leave everything on all the time
7. auto brightness does a good job for me, a mate uses lowest brightness and has no advantages besides having problems reading from the screen sometimes
8. just use it to end apps/games that won't stop after using them like KiesAir
10. true
11. doesn't make a difference
12. sure but whoever needs (e.g. for work) push (like me) will have to skip that
13. see 12.

juice defender is my last option to squeeze more time out of my phone. still with my general usage I get around 36h our of one charge, mostly between 24h and 48h depending on how much I use it AND how good the reception is (better reception -> more battery life)

I have read little about this issue . Instead of renaming or deleting files can we make auto booting script to kill this process so it will no longer looking for a mobile data ?
I have no android skills so am asking somebody who have it. Maybe there is other safe way to ged ride of that battery eating cell standby process
Proudy owner of iconia
Pawel
PS
I have try
(Without doing nothing 50% SCREEN AND WIFI TOGETHER 40 % after change a charg iconia to 100 % and wiape battery stats)
2g/3g mobile data switching best results cel standby takkes only 35% battery
Kill mobile data and prevent to run almost same thing
Cheat with airplne mode same thing
Try to download from market a.k.a batery saver for acer iconia without any results (thor mod with i have is based on assus transformer and market shows incompatible version?)
Dear Pavel,
this is a rather old issue, solved long time ago. You can just add the following lines in your build.prop file, located in the system folder:
ro.carrier=wifi-only
Thor's ROM features this tweak by default so you don't have to do anything - no cell standby.
Well thor rom have this line indeed. And when U check settings about tablet battery indeed isnot showing .
When U install any other app to show battery stats actually shows cell standby and phone idle. I using norton utilities but few other ones shows.
I left for a night tablet screen off, gps off , wi fi on, airplanemode on and after 6h i have 15 % drop down. 8 H on my iconia possible when everithing is off.
Ps
Writing this post 3% down... and tablet was bought on black friday is brand new is that normal ?

If your tablet is new did you fully charge and then discharge the battery to about where it auto shuts off.

There are a couple of things to mention. If you are running an over clocked processor, this will of course use more battery power. Especially with thors roms, because the last time I looked, depending on version, it installed over clocked to 1.5ghz. If you don't need that much, try setting it to 1.2 for example.
Apps that are always running and synching. Things like weather apps, mail, fb, etc. And... those lovely battery apps (a waste of time). And this also includes Norton, as it runs as a process. All of these use battery power.
And as briandigital said, let the battery get a few full changes. Usually takes them about a week to settle down.
I agree with U. Those apps using battery. For example weather widget 0.5 % or norton 0.5 % but still shows 60 + % cell standby or 2% phone idle. wifi over night 30 % with checking mail every 15 min.
Over Clocking got nothing to do with this (1000 on screen on 400 on off) system proces phone is running all the time draining battery.
I have thor 14.2 mod and to get 100 % shure I flash again kernel and dubble chec for wifi-only line.
Wipe battery stats and 10 min after cell stanby 30 % after 30 back to 63 %
Or 5 diffrent apps from market are wrong showing cell standby and system process phone working and draining battery or this all solutins are not really working. If it not showing on /settings /battery is not mean process is not working
Anybody know how to kill that process and prevent to run ?
so can write small script to kill it"

I'll ask you a silly question.
And only because I didn't see it stated anywhere (or I missed it)
Are you running an A500? or an A501?
3g USB Dongle?
Did you run any "update patches" concerning 3g Dongle support?
Reason I ask, is that I did some of the testing for the kernel version you are using. (3.9r3). And frankly, I haven't heard a lot of 500 users complain about "cell standby" with the 14Rom. In fact the combo should be giving you extremely good battery life.
You said it only shows cell standby when using some other different application? I might suggest the app is not telling the truth.
Typically, losing 10% overnight with wifi on, is pretty normal. During testing, I lost 8% on internal 3g, and about 10 or 11 with Wifi. FB and Mail not's set to 1hr intervals. WX at 3hrs.
The fact you still have the menu system for mobile networks (2g/3g) is very puzzling......

You should re-think about posting on Thor's site. He's typically pretty responsive. Unless it's a stupid question, or somebody's not nice.
The cell standby issue is an old one. It's because the 500 and 501 share the same hardware with the exception of internal 3g for the 501. And because of that, the share mostly the same OS code.
Thors rom, was based on the asus transformer. I don't run it, as it doesnt fully support internal 3g.
It's possible, that the process is still running, only hidden from view based on the images you supplied with the modified build.prop set to wifi-only.
In this case, I would ask you again, to post the issue on Thors FORUM under the Rom ver 14 topic. It may take him a day to answer, as he's working on ICS right now.
In the meantime, here at xda in the a500 forum, there are several "older" topics covering cell standby on the a500. One of the fixes at the time, was to "freeze" the telephoney.apk (get some error messages) then reboot.
Just do a search for cell standby, and you'll find them. I found them earlier today through Google (but can't remember where), so you should be able to do the same.
Well I did some research before I bother U and other solutions is to rename / remove phone.apk witch may solid brick my acer. Am wonder if I rename it and hard reset can I be able go to recovery ? And restore prev backup or this is gonna be a perm brick
Sent from my HTC Vision using xda premium
Well Pavil, those posts are a little old.
And, sometimes people call things a "brick" when they really don't know what a brick is
BEFORE I would rename any apps, I would try this, Install Titanium backup. Once installed, and root granted of course, Select the telephony apk, then do a "freeze" on it. Reboot and check things. You may want to freeze those other couple apk's if it doesn't fix it. You will probably get some error messages when you first freeze it, but ignore it, and reboot.
But BEFORE you go freezing things, do a recovery backup first This way, you can get back to where you were before freezing.
Then see how things go.
EDIT. Stop using battery apps designed for phones. They may run on Honeycomb, but if they were designed for devices that have a functioning radio, they know no better than to display an erronous stat.
But honestly, battery stats in android are somewhat misinterpreted.
Example. If your device used 10% power. And the stat says Display used 80%, It means that of that 10%, the display was responsible for 80% of it. Not 80% total battery power.
In the meantime, I see you didn't post on thors site? Ok, I'm on good terms with him, so I'll pose the question to him.

It appears from your screen shots that you don't have your wifi set to disconnect when your screen goes off. I could be mistaken, but if it's not, changing that will help battery life immensely

Yeah, no sense in messing things up. A pity I don't have an a500 or I'd test it myself.
You could try flashing one of the other roms, and see if the result is the same. For example Taboonay. I ran it for quite awhile with Thors 3.9r3 kernel. Or you can use the kernel it comes with.
Answer from Thor is that he's not aware of the cell.standby issue as nobody else has mentioned it, and all his stuff now is set up for ICS, so he doesn't have the time to check it out.
So, maybe you just have to live with it. Seems your battery life is ok, so I would just ignore it for now.
Did you wipe your battery stats from CWM before flashing?... And by the way thor's ROM has CPU clock set to 1.2 GHz by default.
p. s. Moscow Desire is right about apps made for phones.

Yeah, he had to back off the original cpu install recently due to a couple users couldn't flash at that speed (1.5). Not all CPU's are made equal.
(the real issue here, is the old "cell standby" issue that a500's had in the past)
But again, like drkalo affirms, you shouldn't be using battery apps that were designed for phones running android 2.3. I suspect (considering nobody else using Thors roms complain about cell standby), that the phone battery apps have this hard coded, and expect it to be there, so it displays a random percentage. Probably because it see's the phone apk's in the OS and naturally assumes it needs to display something.
Yes, the apps will mostly function on Honeycomb, but, are they really made for tablets? Probably not. (even if they say it does).

So what to use to check ral battery / process usage?
Sent from my EPAD using xda premium
Personally Pavil, I do not use one. Except what comes in the rom. There's really no need to get anything else. And frankly, I don't hear a lot about folks running 3rd party battery apps on their tablets. So I'm not going to be much help on suggesting one. I just know most of the task and battery apps, were designed for phones on android 2.3.
I gave up on things like battery apps, task killers, task monitors and the likes a long time ago. I learned to manage things on my own like most others do. There's no reason, once you learn a little about how android works, to add apps that take even more resources.
Bottom line, you can have every app in the world to monitor things, but what really matters, is what the "actual" battery life is.
For example, I can go 12hrs with normal usage, and still have 60%. This includes internet, sms, mail a few times, maybe some video for an hour. It depends.
Or, I can play angry birds 7 hrs straight before recharge. Not bad! And I run my processor at 1500ghz.
You can instal a cpu app, like cpumaster, and set profiles based on how much battery you have left. I typicaly set mine to start at 1500ghz, then do 2 extras to down the speed based on battery. When I use them, I can run for almost 3 days with normal usage. I do this when I know I will be camping with no electricity.
I have 4 of these profiles on my phone, and the longest I lasted, was almost 4 days before recharge.
Wish I could help you more.
This was on the portal today. It's a Droid Incredible mod that apparently improves battery life dramatically. OP has a full guide in place with info on what each tweak does. Galaxy note devs, amazing as they are, may or may not be using these (or similar) tweaks for the Note. In any case, FYI

More snake oil... Improving your battery life tenfold with sysctl.conf changes when the radio dominates idle battery usage and screen dominates screen-on battery usage = bull****.
Maybe you can improve it a little - but tenfold? Bull****, and a ridiculously exaggerated claim like that makes me distrust any of the changes made.
I know what the prime power eaters on this device are, and sysctl tweaks aren't going to change those... Changing them requires major architectural rework of the kernel.

That's what I thought. You guys know the device inside out, so it makes sense to bring things like this to your attention.
Incidentally, the guy says he gets 50+ hours on a single charge. My Note gives me 48+ hours (with little wi-fi though, and at 1200 MHz), so it's not that we have bad battery life.
Overclocking, init.d changes, etc are all extremely irrelevant in terms of battery use.
The main battery hog for any modern phone in the past 2 years has and always will be the screen (of course unless if you're using something like the Xperia Mini).
I'm more than happy with the Note's battery life to be honest. It's certainly better than the Sensation and One X I had previously.
The only way we will see much of an improvement will be if they make a phone the size of the Note with a 3.5" visible screen. lol
Or a 10000 mA battery.

It's mostly phone calls, the occasional game, some music. Very little wi-fi though, and data only when I need it. Brightness set to auto except when outside (where it's set to max). The fact that I sleep atleast once in those 48 hours helps the battery life a lot

I know what the prime power eaters on this device are, and sysctl tweaks aren't going to change those... Changing them requires major architectural rework of the kernel.

I finished completely charging my Galaxy Note at 02:00 BST. After I got up at 07:00 BST, the battery level was at 86%. I switched off the Wi-Fi, force stopped Skype and WhatsApp (these are the only 2 apps I have installed so far!) before plugging the device to charge.
Background data and Auto-sync in Accounts and sync was turned off ages ago.
Before posting this message, I switched on the Wi-Fi to chat with my cousin via WhatsApp for 20 minutes. Now the Wi-Fi and WhatsApp are inactive. At the moment of typing this message, my battery level is 42%.
I have tried force stopping some of the pre-installed apps such as AccuWeather, ApMobile etc but the effort has been futile. I am aware that I need to root my device in order to get rid of the bloatwares. I am having another issue with the Auto brightness feature which I have described in another thread. I have not ventured into the realm of rooting until now because I may decide to send my device to Samsung's service centre.
I cannot figure out for myself whether my battery or my device itself has a flaw or whether it is normal and there is nothing wrong.
I will eventually pose my queries pertaining to rooting and relevant subjects. I am a novice in the field of mobile computing and I am here to learn from you all.
Thank you all for your continued patience.
Your device has a flaw, that flaw is called Skype.
Skype is a notorious battery drainer.

Thank you for your prompt response Entropy512.
After I finish using Skype and subsequently signing out, I force stop it from Settings > Applications > Manage applications, either from Downloaded or All.
I use Skype on my phone to communicate with my sister when I am away from my computer at home, especially when I am at university. Thus, I am compelled to use it.
Do you reckon force stop is turning out futile? Should I get a third party "task manager" because the default/pre-installed Task manager seems incompetent.
Please do keep your expert opinions, suggestions and advise coming.

Install BetterBatteryStats (free if download from xda). Check for wakelock to see what app is keeping your device awake.
Just as a note, there is a bug in the OS for our Note if you use the USB OTG cable. Once plugged in with any USB storage device, the unmounter process would cause the device to unable to sleep, thus causing battery drain. The only way out is to reboot.

Hello everyone,
My battery drains so fast and I don't know what to do.
It seems an application is open that drains it but I cannot turn it off.
Please check the screenshot

Doubt it but what is true is that you and the OP did not even bother to read the rules or the stickies .
Thousands of battery drain posts all identical you cannot expect members to continually point out the basics that is not what this forum is for .

You might need to close all your running applications. Plus close wifi, sync & others when not in need. Or it could also be your downloaded apps that have advertisements on it. This will automatically lights up your phone even on stand by mode. Try uninstalling them, download ad free apps on google play so you will know what are your installed apps that have ads on it. Hope these help!
Depending on what you are running on your phone, ie; Stock Samsung Official Firmware or Custom Firmware Via CWM etc,
There are many many posts about battery drain & how to solve the problem, I thought the same, but I persisted and found what I needed.
OK, I am sure you know about custom roms, some stable, some not. many have battery drain problems, many dont.
I advise if you are running a custom rom, go to the thread for that rom and read about any problems about battery, if not post in the thread
and ask the person who made the rom for help. battery drain could be anything, which includes a bad flash or installation.
Anyway I hope you get sorted.
Every time i hear somebody suggests To close almost everything that make a smartphone deferent than a common phone I wonder if android has many problems to solve.. A smartphone is smart because of the services that it offers...

Totally agree redcom7, a smartphone is just that, if everything is turned off then what's the point???
Android is not perfect but it is pretty dam good, battery drain issues are more likely in custom roms.
I am running a custom rom which I researched prior to install, now it's in it lasts on average 14 - 19 hrs longer than the Official Firmware
and that is with everything running.
You are right everything does not need turned off, just a bit of common sense mixed with research and everything should be fine. :good:
I am running omega rom.
The thing is that when I flashed this rom it didn't have battery issues. But now it does!
So I thought an application drains the battery and I wiped everything but it still drains it.
The app is called media as you can see on my screenshot.
I really don't know what to do...
I wiped battery stats and it seems better now...
I'm thinking of changing kernel. Would that help?

I m just wondering to find whats the normal battery timing of Samsung Galaxy S3 GT-I9300 ?
My phone battery timing is about a day with normal usage.
Its 4.1 J.B
And I also want to find out some new tips and tricks.
Thanks.
(I m a new member)
Depends on use. Stock I only get about 7 hours with my use. With tweaking I usually double my battery life.

You have the media scanner bug. There are various solutions but the most common one is to reformat your SD card.
You can stop it happening temporarily by force closing media scanner but it will return when you reboot the phone.

Kernel Yank555.lu-V2.7a
'Rescan media root' solved a problem I was having with battery drain from media.
Also, I also used to think that shutting down some android services was defeating the purpose of having a smart phone. Unfortunately, I was losing 20-30% battery when at work for about 5 hours. Recently I've started switching off data while working (I can't use my phone when working anyway) and now my drain over the same amount of time would be around 5%.

I put another sd card and I'll see how it goes now.
Just to mention after 30 mins battery is at 98%
Ok guys! Problem solved! :good:

Thread closed, post in the Q & A section next time.
Any idea how to know whats running Using the android system. Its sending data somewhere i think and its draining my battery as well. Adds up heating my phone up as well.
My battery went down from 97% to the one indicated in the screenshot. Help please... Im beginning to hate android now with this lackluster battery life. This just happened yesterday. Everything was fone before that.

I think I have this problem too. Or I'm really paranoid about my battery. I did a factory reset a few days ago, but it was fine before that. Usually my screen is the #1 battery consumer, now Android System is 75%.
Did you update your firmware? I'm running ME2 and had no problems whatsoever before that.
I downloaded "battery stats plus" and the issue might be the "camera test"?
I dont think the firmware updated has something to do with it? Not sure though.
Sent from my GT-I9505 using Tapatalk 2
Downloaded that app, and Camera Test shows pretty high on mine as well. About 1,73% though, but with a bit over 5 hours without charging. It's been using my camera sensor 2 hours out of 5.
I think this is a really good case for the experts in the better battery stats thread. They have a special procedure to help you quickly solve the problem.
Read the OP, or if its a multiple post OP read them. It says exactly how to let the phone sit idle (i think I recall its 4 hours) and get some specific info and post it and they will help you narrow down exactly what's causing it but also give a solution.
I have a job interview in just a bit, and am in a hurry but wanted to share that with you.
I have an idea what the problem might be and those guys actually have a really good solution to fix it without having to eliminate anything and just changing some settings.

Thanks for the input Charles, I'll definitely try there. I see a few others in the thread might be having the same problem as us.
And I thought after buying my S4 I'd be happy forever after... +1 thanks to you.
Same here... Im beginning to hate android... Im close to throwing this phone on a brick wall... This is my 4th time to reset due to settings acting up and ruining battery life.

Looks like i fixed the issue somehow...
I think google and samsung apps might be the problem. Tried to open and setup to not use any data on all google and samsung apps. Namely google setting app, samsung hub, samsung link, Keis, etc.
Update them all via samsung hub and possibly download kies air from samsung app store. Was trying to setup them while charging the phone. Location based apps was also turned off for using gps or data. Turned off notifications on them as well unless you do want to be notified.
