Plus Post for anyone.....we seem to forget the things that kill us....back stab us the most when it comes to Battery Life!!

GOOD POST!!! VERY DETAILED AND INFORMANT!!!!
[T-Mobile, Samsung Galaxy SIII] Tomaxda:
Great advice on the whole, but I don't agree with the stuff about app widgets.

Widgets don't use a bunch of resources just because they are widgets - I think you could almost say the opposite: the design of widgets allows them to be visible on your desktop without using any resources because the app code that controls the widget only needs to be loaded when the widget changes.

In the end, the resources used by an app widget depend on what it does and how it is designed - same as for any app. If your widget is supposed to go to the network and update some info for you every few minutes then this will drain your battery. However, there are tons of utility widgets that do nothing (and are not in memory) unless they are pressed or one of the phone states they are listening to changes (e.g. a radio is turned on).

Of course, a badly designed app will hurt your battery regardless. Personally I think apps need to get away from creating a custom Application object since these get instantiated whenever the system creates the app's (or app widget's) process, even if it is just to update a widget.

Nice thread

Thxs for this nice thread :) Any ore would be appreciated.

I have learned a few things besides already being techy.

Nice to see whole lot of apps for android :)
[T-Mobile, Samsung Galaxy SIII] GermainZ:
I disagree about the widgets part.

Sure, putting them for the looks (e.g. putting a huge clock widget when your lock screen and status bar already show that info) might be useless and redundant, as you say.

But other widgets (e.g.quick notes, schedule widgets, maybe even a news widget that syncs once a day) are perfectly understandable, especially for some home configurations that prefer simplicity.

As an example, I'll give my home screen: it consists of three pages, one of them is empty, the other two contain three widgets: notes, schedule and news (syncs once a day automatically). The dock contains 5 items, each of them has one or two gestures assigned. The dock's middle icon opens the app drawer, divided into several tabs.

In order to open each of these widgets' apps' screens that interest me, it would take me between two and four clicks and one or two swipes to get there.

Considering I use them regularly (the notes and schedule widgets, a few times times a day [3-5 each] and the news widget, once or twice), it would be way faster and more efficient to have the widgets instead of removing them or replacing them with icons (should I do that, it will still take me one to three clicks to get where I want, plus the loading time).

Plus what Tomaxda said about widgets.

Also, I'd suggest adding Tasker to your list of apps. It's not for the lazy people, but I can get it to do all of what the apps you listed do. ;)

Sorry for the block of text. Great guide.
[T-Mobile, Samsung Galaxy SIII] ngocdao:
Thanks for the tips!. I guess juicedefender is effecti\ve then.

I dont know if it's just me but the S3's (stock) TouchWiz Task Mgr seems hmm.. not as efficient as it's predecessors, in governing it's processes and regularly dumping/cycling idle processes as needed...?

just wanted to share my personal setting....

my battery life has greatly improved just by (in settings->dev. options) limiting background processes to

4

and setting 1) window 2) transition 3) animator scales all to 0.5x.

hope it helps you too :)

[T-Mobile, Samsung Galaxy SIII] skusa93:
Excellent list, but I would definitely do a section on custom brightness settings for those of us on a CM10 based ROM.

I can post my settings for comparison;

Here is a screenshot of my battery life right now, I charged it midday because I didn't get to last night but this is really heavy usage with GPS on 100% of the time.

You will also need to adjust the other settings like window length, reset threshold, etc.
[T-Mobile, Samsung Galaxy SIII] Surfinette:
@woodrube

Thank you for your great post. Quite some useful tips.

I'm impressed by you battery usage graphs, especially the fact that you managed to have your screen on for over 6h...(I'm more like 4h30-5h00). However, I wonder if you could not improve your battery life even further as I notice your phone it's often awake while screen off during the night. Also do you need phone/data connexion during the night? I personally set my phone to airplane mode during the night (JD or some free apps can do this automatically for you and it won't prevent the alarm clock to ring in the morning).

As to JuiceDefender, I now have great doubts (still unresolved) about this app.

I've been using JD on all my phones for over 2 years in expert mode exactly as you recommend. But since moving to a SGS3 I'm not so convinced that it is so useful at least with this phone. I noticed there was an issue with JD when realising thanks to BetterBatterystats that JD kept awaking the phone while screen off even during the night when my phone was supposed to be deep asleep in airplane mode....

I've now tested using my phone without JD.... I manually set Wi-Fi on/off when I go home/leave home. Since I stopped using JD, my battery holds much better during the night than before...I don't know if it's me poorly configuring JD or if it is specific to JD+SGS3... I still need to investigate.

A trick I now use to save battery is that I've set my phone to 2G only which uses much less battery than 3G and is enough for background sync of emails, news, social media, and also enough for audio streaming. When I really need heavy data usage and I'm not in a Wi-Fi zone then I manually switch to 3G.
[T-Mobile, Samsung Galaxy SIII] iArmghan:
I have a question related to Juice Defender. I just setup the juice defender in advance mode and config scheduler to autosync after 30minutes but is it necessary to enable Autosync from the settings menu of the device for Scheduler to work or it works independently ?
[T-Mobile, Samsung Galaxy SIII] Entropy512:
Please remove all of the battery calibrator/wipe battery stats crap.

IT IS 100% PURE PLACEBO. IT HAS ZERO EFFECT ON BATTERY LIFE. THERE'S A REASON IT IS GETTING REMOVED FROM CWM! (The only reason it hasn't already been removed is because Koush was lazy and didn't resolve the merge conflict when the error popped up - http://review.cyanogenmod.org/#/c/16878/ )

Seriously, if you don't believe me, believe Dianne - https://plus.google.com/u/0/105051985738280261832/posts/FV3LVtdVxPT
[T-Mobile, Samsung Galaxy SIII] Woody:
Sorry I haven't responded in the last day or so. I've had a two day migraine. Will respond to everyone tomorrow.

@Entropy, I already gave that G+ post by Dianne in the calibration section and Battstats myth being debugged. I've even explicitly stated that it does not increase battery life. It is for when your settings>battery stats are not reading correctly.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
All due respect, I do know you have done a lot for the community, but please read on....

The very FIRST line regarding the Battery Calibrator:

and at the end, he not only mentions and links to Dianne Hackborn, but he quotes the exact post you suggested he read!

Don't get me wrong, I agree with attempting to set things straight when someone makes an incorrect claim, and I agree with what you have to say, only it needs to be in countless other threads, not here. Woodrube has it covered! :good: :cool:

Thanks!

[T-Mobile, Samsung Galaxy SIII] mattedwards2686:
Thank you for posting this. Hopefully, this will put an end to all the questions!
[T-Mobile, Samsung Galaxy SIII] Woody:
Ok here comes a massive Multi-Quote:

^^^ Noted and updated the OP with that. I have since seen this mentioned as well.

^^^This will also be put in the OP as well. GPS and Location "polling" will definitely eat at your battery.

^^^ For both.

The widgets part of my post is mainly about "polling" apps, like News feeds, Twitter/FB/G+, Gmail/Email, Schedulers that have to sync with your accounts,...Not something like UCCW/Clock or Gallery, those type widgets. Anything that opens up your radios for notificiations or stream will eat your battery. If I have 4 widgets on my home screens that are for 4 different sites and are scheduled to sync every few hours, then at some point there will probably be one "turned on" at any given time interval.

But to each their own.

Also the Tasker app is a great idea. I've used it before and can't believe I forgot to put it in there. Thanks for the suggestions.

Even if your radios are set to off for the middle of the night, that is fine bc you will still receive phone calls. One thing about JD that you need to remember is that User take precedence. Meaning it you have something set in Settings on your phone like Wifi preferences, then JD will adhere to those preferences. In JD+, there is a setting for night mode. I have mine set from 12am-8am, where it will shut off the radios during that time....Unless I am "currently" using it. Meaning if I am using the XDA app at 12:30am, then I take priority. Once I shut down the XDA app, then JD+ takes over and it is quiet time, unless I, the User, opens up the radios/Apps for some reason.

For your second part, I don't think that you are set up correctly. The partial wakelocks that I get are not enough to prevent it from coming out of Deep Sleep. Not sure what the problem is there, but feel free to PM me if you want and we can try to figure it out.

User take priority over Juice Defender. That means if you set up Auto-synch in Phone Settings, then that will take precedence over you Juice Defender settings.

***************************************

@All, thanks for all the kind words and I was equally surprised to see it on the Portal. Thanks to whoever submitted it as a NewsTips.

As I have said in the beginning, I am always open to new tips and tricks and if I find some that work out well, I will sure put them in the OP (and give credit). Again, thanks to all and keep them coming.
[T-Mobile, Samsung Galaxy SIII] Entropy512:
Sorry, but that's BS too. It does NOT even affect your fuel gauge reading AT ALL, so your claim of "but will give you a truer reading if your battstats somehow get corrupted." is FALSE.

Seriously, I challenge you to find a single fuel gauge driver that has ANY inputs from the battery stats file.

Simply put, if you are referencing the CWM "wipe battery stats" option or any battery calibrations, you're peddling pure placebo crap. They should not be in this article AT ALL as they do ABSOLUTELY NOTHING USEFUL WHATSOEVER, and any claims that they do something remotely useful is pure misinformation. The ONLY mention of these functions in any proper guide should be, "Do not use them, they are utterly and completely worthless."

Nuking that file will ONLY affect the detailed reporting in Settings->Battery, and merely charging your device to 100% will force a reset anyway. (No need to do 34 full charge/discharge cycles with a voodoo dance in between every one - just connect your device and leave it on the charger a while and NOTHING ELSE.)
[T-Mobile, Samsung Galaxy SIII] Woody:
So you are telling me that these things here are not all stating the exact same thing? I know that deleting Battstats does not prolong your battery life and that doing so will just delete the stats shown in Settings>Battery until you plug it in and recharge to full 100% anyways. I will edit that part of the section to make this more clear, as well.

I respect you and your ERD status, but please show me the same and cool down your tone in my thread. If you have some issues with me, then please feel free to PM me. But as is, I would appreciate the same respect in your posts as I would show posting in your threads.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
I agree, thought id also point out that twice, very recently, there were folks that had a problem where the battery percentage would not change. Didnt matter if they were using it heavily or if it was on the charger for a while.

Yes itll reset when it reaches 100% (Actually I think it resets at 90%), but not always if its stuck like that.

And even so, they didnt know and went searching/posting for a fix. Wiping battstats fixed it. Sure theres probably other ways as well, but this was quick and easy.

Just thought id share.
[T-Mobile, Samsung Galaxy SIII] tsmvengy:
My girlfriend recently got the AT&T GS3 and was having big battery issues - the battery was constantly hot and the phone was constantly draining fast and would be done in 4 hours. Personally I don't believe people should have to solve this issue with gimmicky crap like turning data off when the phone sleeps, setting the brightness so low you can barely see things, etc. The phone battery is designed to last a day+ with normal use, so issues like the battery crapping out in 4 hours point to something deeper. I took a look around and found the following:

(I can't post the link but it is an ATT forums post called "Samsung Galaxy S3 Battery Drain (sudden drop)" and the steps are on the second page)

I followed these steps from user "erickb1800":

There was no Samsung Account under Accounts & Sync so I did not have to delete that. But I did disable those 5 apps listed in step 3 and it basically made the problem go away. One of them was using CPU constantly in the background (it only showed up as "Android OS" in the battery page tho) and disabling them seems to have solved the problem.
[T-Mobile, Samsung Galaxy SIII] goodtimes50:
I have Apex Pro and I can't seem to find this option anywhere! Could someone point me in the right direction?

Just use any icon on your homescreen and long-press it. There will be a window that pops up with Remove, Edit, App Info and Share. Hit App Info and there you are.
[T-Mobile, Samsung Galaxy SIII] jerverg:
Won't using the Fastboot use up more juice than conserve? Because you are refreshing some processes like the launcher, keyboard, and other system processes and then they would reboot thus using juice? I think using GO task manager or the original "RAM clearer" in the S3's task manager would be better as they are not closing the system apps like the launcher itself.
[T-Mobile, Samsung Galaxy SIII] iArmghan:
Improved Battery Life :)

I tried many different settings and tweaks but the simple steps worked for me are

1) Turning off Google Now and Location

2) Using Fastboot before locking device

3) Advance Task Manager Pro to kill tasks

I tried Juice Defender too but it was more off a battery drainer than battery saver :P
[T-Mobile, Samsung Galaxy SIII] Romcrazguy:
wow impressive what rom/kernel are using and your setting on juice defender???
[T-Mobile, Samsung Galaxy SIII] iArmghan:
I am using CM 10 with its stock kernel :) Juice Defender have some issues with S3 It drains a lot of battery in standby mode.
[T-Mobile, Samsung Galaxy SIII] Woody:
That means that you don't have it set up correctly. It shouldn't drain hardly any battery in standby (if it does, it should be a negligable amount). PM me and I will help you figure what is happening with it.
[T-Mobile, Samsung Galaxy SIII] Popolon2:
11 days on batterie on Galaxy S

Not to hard to be 11 days on Galaxy S 1 (on an official froyo 2.3 Samsung rom), only have to kill 1 or 2 times a day and at each connection/unconnection all these crappy and unwanterd *Google* applications (maps, vocal search, gmail, and some other, I like Android, but I don't have and don't want a Google account). As that's my first post, I can't post link/picture link, but see by yourself here:

popolon.online.fr/GalaxyS-10jours_23h_sur_batterie.jpg

I also noticed than some simple education applications could take lot of ressources. That's the same than on computer, there are generally really simple but really badly coded too. For example I seen in some infinite loop in wait for event instead of calling a sleep of one second for each looping.
[T-Mobile, Samsung Galaxy SIII] jazee:
Perfecting timing on your recent post. Just got an HTC One X+ with the higher clocked CPU and bigger battery. Coming from an old iPhone 4 jailbroken with all sorts of "widgets" on the lock screen. Oh my God the battery on this HTC drains so fast! Sill learning the ins and outs of Jelly Bean and HTC Sense but once I was able to fine the process list, holy crap, what is all this stuff doing running!!?

So how to you close an app "all the way" so it stops running in the background? Is there not some sort of keypress, or do you just have to constantly check your processes and close them out. I know, a total newbie question I'm guessing.

I'm loving the new phone but probably mostly because it is new and faster than lightning compared to the old iPhone 4, but the widget functionality (and no, I'm not running a bunch of widgets, removed them all except one) is lame compared to running Intelliscreen X on iPhone and the battery life, holy moly, have you seen some test graphs compared to the iPhone 5. I'm sticking with Jelly Bean but geez, Apple sure whomped Android (most devices) on the battery efficiency front.
[T-Mobile, Samsung Galaxy SIII] rookiegenius:

Sent from my Galaxy S3 using neighbors wifi :P
[T-Mobile, Samsung Galaxy SIII] Woody:
What ROM are you running? I don't use the Power Saver mode because I've read it interferes with a few apps, plus with some of my tweaks, it seems a bit redundant and could be problematic due to the "too many irons in the fire" type situation.

Regarding "Matte Screen Filter".. I've tried a few similar apps and while they seem to dim the screen (no doubt), I am not so sure if they are doing this by actually reducing the display's brightness. Rather, it feels like it is just a (gray?) overlay on entire screen. So, how much battery does this actually save? If I understand correctly, OLED displays when displaying black the pixel(s) are turned off. So, wouldn't the overlay still light them to some extent?

Using S3's "negative colors" under accessibility, you can see the haze of these filters on a true black wallpaper. Did anyone try this and more importantly, is there any app that can "really" dim the screen without these overlay filters?

Calling out to the SGS3 users (This is read by more than just our forum section).

Since we now have stable 4.1.x ROMs out there and many have moved on to 4.2.1/2 ROMs, I am asking if anyone could please give me thier OC/UV settings and which ROM/Kernel combos you are using. I want to put some different ones in the OPs for people to reference. I need something that you have ran for about a week

minimum

and any type of performance issues you may have encounter (only) because of the OC/UV.

TW, AOSP, AOKP, CM all apply since we are pretty scattered out there in what we all like. It would behoove many if we could get a few from each variant base. I don't care about the ROM (Darth, Liquid, RootBox, Ingenious), it is the kernel OC/UV that I am after.

Thanks to all. You can either post here or PM them to me.
[T-Mobile, Samsung Galaxy SIII] westhillsat:
Thanks for the great guide. I've always liked the free version of Cache Mate that you had mentioned.

I've rooted all my previous android phones and just rooted my newer S3. Trying a new rom so after I've had it for a week or so I'll report on the kernel. Have only been using the new one a few days, but so far great battery life for me.
