Fixing battery drain on your s3

I have done pretty extensive testing in the last few days and this is what I found.
TOUCHWIZZ USERS ONLY, uninstall and delete data for the app my uploads. It syncs your gallery with picasa and uses a load ofdata and battery. It won't break anything. turn off instant upload in Google+. Turn off smart stay and motion actions. they use about every sensor in your phone. Turn off the wake up phrase in s-voice. If its on it is always listening for that phrase. I'll keep looking for other things but I got fairly good battery life just doing those things right there.
When uninstalling an app, wipe cache and data first. This will clear any background processes that could stay after the app is gone.
Install es task manager and kill everything you don't need to run on startup to preserve boot time/battery usage. Also it will keep the processors a lot lower.
All accelerometer and other hardware functions use a significant portion of your battery. If you don't use landscape mode turn auto rotate off because it uses that precious battery life.
Weather bar in notification drop down and on your lockscreen will destroy your battery life. Weather widgets also use quite a bit of battery.
Facebook app also kills your battery because its always connected to the internet. Syncing Facebook account to your phone further wears down your battery. Any game or other app that connects to facebook will also do the same.
Look in data usage under settings. Anything on that list uses more battery because its connected to the internet.
If your not in an lte area turn lte mode off because your device will be searching for a signal it will never get.
Low signal strength kills your battery because your phone has to use more energy to hold connection to the network. If you have WiFi at home and bad cell service (or anywhere) use WiFi because its easier it is for your phone to hold good wifi signal than bad cell signal. also turn off your NFC. It uses more battery than Bluetooth does.
Get better battery stats app and look for wake locks because without deep sleep you will never get more than 12 hours battery life.
Widgets, live wallpapers, lock screen ripples and other things that move use battery also. If you don't use it then remove it to save a couple percent a day.
Remember that when charging through a computer USB port or things like that charge a lot slower than an outlet. Slow charging is better than fast charging because your battery stays cooler and that means your batteries total life will be longer.
Finally before you go in a ROM thread and start complaining about battery life, go at least three charge cycles after flashing to optimize your battery.
There are many things that cause battery drain so beware when you download that next app. It could be a battery sucker. If you don't need or don't use an app. Uninstall it because it may have background processes that are using up battery and RAM.

The other thing I might add is the "wake up phrase" where ever that is. I found it yesterday and turned it off. Helped a lot.

I think this is pretty good, what do you all think?

You can uninstall the facebook app, go to facebook on your browser, create a bookmark, and then place a widget on your homescreen for that bookmark. The site is actually faster than the app.

In my opinion maximizing battery life is all about watching out for the things on your phone that you don't care much about but are using a lot of battery life versus keeping the features you like that make your phone a smart phone.
I leave GPS on all the time, use auto brightness, have fb and fb messenger installed, use Google talk all the time, push my work email, etc. and accept the fact that this will cost me about 2% per hour when my phone is idle. I'm also using the latest ktoonsez kernel & task/kt jellybean rom and those help tremendously on battery life (1h45m since unplugging today, 51m of screen time and I'm at 89%). I have definitely been diligent about turning off the things I don't care about, like latitude, location in Facebook, rom weather, etc. and that helps quite a bit. My biggest problem has been maps running for no reason and draining lots of battery, but that sends to be a lot better with the latest rom and kernel.

ii.Mediaserver. This system process is tricky when it comes to battery. What happens is that whenever you access any sort of media on your external SD card (playing music, gallery, what have you), this process kicks off. Luckily though (but hard to catch), sometimes, this process uses more process time than it should due to corrupted contents on your external SD card. In order to catch this culprit: try clearing your battery stats (for example, restarting your device or coming off AC power), playing some music and/or checking out pictures on your SD card for a few hours. Then, check your processes. If Mediaserver is high up there in usage, you may want to consider cleaning up your SD card. Naturally, we would expect that the process is higher when media contents are in use. I can’t give you a specific guideline such as, "something is up if Mediaserver consumes over 25% battery." This is another example of where you should look up other user stats for system processes based on your specific phone and OS version. If you think your SD card may be corrupted, backup your data, format the device, and slowly, add back files and repeating your media tests. Finding a corrupted file isn’t a guarantee, but this doesn’t hurt if you suspect data corruption.​[/QUOTE]

Turn off GPS when not in need. Turn off WiFi when not near wifi. All the stuff in the op. And undervolted by 100+ mv on every CPU setting. And my phone is absolutely lag free accept when I hit the unlock button it takes like half a second for the screen to come on instead of instantly (160mv undervolted on 192 which is sleep speed I set)

Maps is known for that. If you don't mind my asking what do you use maps for and could you just use Google now to search locations and it will even give you traffic n stuff. That would probably get you another hour or so a day.

Tips and tricks: improve JB idle battery life.

Confirm the following option is unchecked:
Maps/Settings/Location settings/Report from this device.
If it is checked, uncheck it.
Here's the difference in battery life -
About half the battery drain with the option unchecked.

Thanks for the tip

What are you talking about? Did you zoom in to see screen on/awake usage? Both are about 7.5 hours of idle time.

I updated my phone to JB and followed the battery saving measures and the battery is dropping very quickly.
Before it could last up to 3 days in standby, now I'll be surprised if it lasts 8 hours.
I'll give it another day then try a factory reset if it does not improve.
Anybody else seeing this?
I have watchdog on the phone and it shows zero cpu off time.

Just install better battery stats, there is also a way to dump the same info in terminal but I don't use it. You are looking for alarms apps cause. It's most likely maps, followed by talk, exchange client, or anything like Twitter, FB,g+,stocks.... but most likely maps location settings
Sent from my SPH-L710 using Tapatalk 2

I have been doing a lot of research and the end result is that JB out of the box will eat your battery and yes disabling the settings under maps does in fact help a lot but there is a lot more you can do to get good life... for starters get the simple stuff out of the way, DELETE FACEBOOK MOBILE APP!!!...and twitter and anything that actively accesses the internet in the background... I know this may sound taxing but it is so worth it if yiu just make a bookmark in your browser and view it periodically than have an always active app... next if you are not in a primarily lte covered area set your phone to cdma only... go into settings and go to data usage and here you can see what is using data in the background I.e. facebook... and go there and check the restrict app box.., disable auto brightness and some have said that if you disable sprint connection manager thing you can do even more.... now that one I cannot be sure about I will post results in the coming days of what I find

You are pretty much correct the FB app sucks but I never really had much problems with it.
A lot of these tips though in general (not directed towards you) are stupid.
Like someone said a while ago I refuse to gimp my phone to sip a little bit more life out of it. What's the use of having a smartphone if you're not going to use it like one.
I always have high brightness unless its dark out. I broke my syncs intervals up to about 4 hours per sync and have push notifications from twitter and weather.
With those apps all I have to do is refresh when I enter the app having those syncing all the time is worthless unless you're constantly checking every 10 seconds.
I say I get fairly decent battery life granted I'm on wifi most the time and 7-8 hours with about 2 hrs screen on playing HD games youtube poweramp and my background processes.

Well in regards to the act of extending the life of your battery these are simply tips that you can utilize in the event you are someone who is out for extreme amounts of time.... I average anywhere from 13 to 17 hrs of battery life with 100% brightness, wifi 3g all of my favorite apps... instagram xda kik kindle Skype etc. And 5 to 6 hrs of screen on time. .. so these gimping tactics more than double my phones live time and doubles my life.... but hey if you can get to a charger after 8hrs by all means but for the most part I cannot until after 13 but i do in fact appreciate your incite

Also even though you are disabling sone of these apps like google now.... you can still use it your just turning off the background nonsense

what rom and kernel are u using

Even with changing that setting in Maps I still am not getting the same battery life as I did with ICS. Maps is still coming up as my most used app when I check battery usage even though I rarely use it. Wonder if it may be Google Now causing Maps to keep running.

Oh wow. Sorry from my phone I couldn't zoom in. I see now lol. Thought I saw 90 and 89 or something like that

I had the Maps setting turned off for a few days and also had A LOT of stuff disabled, but unfortunately my battery life (and my wife's as well) wasn't as good as ICS, and quite a bit worse actually.
Sadly, today, it looks like I figured out what the killer is:
Google Now.
This morning, 100% charged, I turned it off. My wife (who still had it on) and I were out and about together for about four hours, we both barely used out phones for that time. When we got home I checked both phones: I was at 96%, she was at 80%.
The only difference that I hadn't already accounted for:
Google Now.
So, unfortunately, it looks to me like one of the two biggest reasons for wanting JB in the first place (Butter being the other of course) turns out to be a big battery hog I don't yet know if there's maybe some setting within it that is a specific problem or if it's the whole thing in general... maybe you just need to disable a card or change an update frequency or something (I didn't touch any so I'm running whatever the defaults are), I don't know yet... but all indications are that's where the problem lies.
That, my friends, sucks.

Well since my phone has calmed down I am getting 13-16 hr easily. Brightness maxed of course and about 4-6 screen on time I will never cripple my phone. Hell I bought it so I can use not to look at. Lol thanks for the post of this though if I'm ever I. A die hard , situation I'll know what to do

Google Now uses the "Report from this device" and "Enable location history" maps location settings to determine your driving patterns so it can suggest alternative routes and report traffic delays. Disabling "Enable location history" will disable the driving pattern suggestions completely.
FWIW Settings | More settings | Mobile networks | Network mode
Changing from "CDMA" to "LTE / CDMA" has gained me better battery life. My wife also noticed the same.

(To save time, I'm cutting & pasting my post from another similar thread.)

"I have had my Galaxy S3 for a week now. Battery life stabilized after the initial syncing, etc. I updated to Jelly Bean v4.1.1 two days ago, and battery life didn't seem noticeably different. However, that was until today. My phone was off of the charger, around 10AM, and had < 5% charge by 4:30PM. I was very busy, so I was hardly using the phone all day. It was in my pocket or on my desk most of the time. One of the only settings I changed last night, was enabling 'Use wireless networks' and enabling 'Location and Google search' under 'Location Services' in 'Settings'. I just disabled both settings, and will see if the battery drain is any less tomorrow. Also, Google Now was off, and was never enabled on my phone. I'll try to post the results, if at all possible..."
So, for me, it seems to be Location Services may have caused my poor battery life, and was definitly not Google Now, as it was never enabled. I'll try using the phone with the settings off, and see if that changes anything...

I do love Jelly Bean; as it is ICS only improved or enhanced. But battery life has definitely taken a hit. I can barely make it through 24 hrs. On ICS I could do a day and a half to two days with really light use. I've tried just about everything mentioned with little change. Good thing I have an extra battery. Thank you Samsung for making a phone with a user replaceable battery.
Thanks for all the ideas/suggestions anyways,

I noticed the huge difference as well. I was walking around Chicago yesterday and not using my phone. After 4 hours I looked and my battery was at 50 %.

Hello,
as everyone im really happy with my GN2.. everyone says that the battery just drops 1% percent everyhoure..?? thats not the case with me.. it drops 10%-15%.. is there any settings you have done?? its still on stock rom didnt rooted YET
I didnt install/download any virus or fool apps from playstore (Ive read many threads but they were all the one who downloaded just random apps from playstore and that caused for battery drain..)

A normal Galaxy Note 2 has a 1% drain every 10-20 minutes of screen-on time.
The screen-off time of the Galaxy Note 2 is indefinite. Depends on what you have on

haha when i first saw that i thought wOott 1% / hour impossible.. but when more persons said the same i thought "hmm maybe I'm wrong".. so they are ****ting maybe D

No, I don't actually. I do not know what the screen-on time from persons' who have sync on.
I usually get 7++ or 8 hours screen-on time, from my usage.
That's with wifi, games, phone calls, messaging.

Wow. Wifi and data on? You must have super internet, man! Coolness!

I've left the office just about an hour ago... Charge was 100% and I have opened video (auto-play next=ON) playlist. Trip to home has took about 40 mins and every single second device has played videos, non stop.. No app, nothing special. When I arrived, the charge was 99%
It's probably has its very own battery optimizing systems inside which is clearly avoiding energy leaks.
I guess, I don't need anything for now to improve charge durability... Just fyi about my little test~

Hello again,
Actually our phones need nothing for better pattery durability. But if you wonder your battery specifications, i would like to recommend "Battery HD Pro" from google play market. It supports Turkish language and more.
Good luck.

The gnote2 loses ~10% an hour on WiFi and ~15% on mobile data. You can get more than 10h reading books with white text on black background. And videos on internal/external storage can get you more than 10h display depending on the video. I generally get about 10h display in WiFi and 6-7h on a workday where I use mobile data and I haven't flashed a custom kernel yet. Too much extraneous junk with the current kernels. Just looking for one that allows custom voltages on various things, mainly CPU and GPU.

I don't use any power saving apps. I have everything turned on and syncing 3 email accounts. I lose 1% overnight and rarely lose a percentage when the screen is off. What did I do? Just turned off google now and the 3 tick marks under GPS setting. Good luck!

[q] at my breaking point with battery drain

I know this horse has been beat to death, I'm just hoping I can get maybe one bit of info that will help me resolve this issue before I just swap out to another phone. I really don't want to, but I'm just so sick of being chained to a charging cord all day. My phone should be able to hold a charge for at least 1 day, I don't even use it that much!
So with my little tirade out of the way, let me give you the facts I've got a Samsung Galaxy S II/SPH-D710, and the battery just drains down so fast, and the phone's barely 6 months old. I've downloaded numerous process monitoring apps, designed to see what's going on, and they all point at WiFi being the culprit. The phone never hits deep sleep because the wireless is keeping it awake. Sure enough if I turn WiFi off and I go 3G/4G all day my battery is fine. Problem is I can't get to that next level and find out what program or process is causing the WiFi to be on all the time. Even more frustrating, every time there's an upgrade like FI27 or FL24 which I'm on now, the battery works fine for a day or two. Then something kicks in and destroys the battery. My thought is it's got to be an app, I just don't know which one.
So before I kick this piece of **** out the window, I was hoping someone could please help me figure out what app/process is the cause of my battery drain.

Get DS Battery Saver. It will force all of your stuff off when you turn off the screen so that it will go into deep sleep.

Apps, batteries, ics vodoo it's a host of things that can solve your battery drain issue. Being that your phone is 6 months old I have to rule out the battery. The fact that your on ics is going to be main culprit, stock ics was not the best at managing battery use. There's something revving the crap out of your Wi-Fi, while Wi-Fi is on even while your screen is off there are processes going on in the background that are using Wi-Fi to send receive, update, sync, you name it and all you need to do is pinpoint these processes.
Some apps in the play store can help, but some of these apps can consume battery also, so it's best to delete it after troubleshooting.
If your phone is working properly and your not a social media junkie while it sleeps it should not be using any battery at all, just enough to keep your processor awake.
I keep notifications are sync off on my phone, while I'm out and about I'll check email or do a quick sync if I want to check for some incoming whatever. Most of the time I want info on my terms, not every minute with chimes beeps or lights flashing.
If you use google maps disable background location reporting, location services just use "location and search " disable Wi-Fi and GPS usage for location services.
This is a start, but I recommend Jb ga10 stock/rooted to give your phone a stable os.
I run stock/rooted Jb de-bloated with minimal apps, no games (all the games I like are on my Galaxy Tab 10.1) I use my phone for calls........... navigation and media player while driving. I get 16 to 20 hrs on a charge.

I get about 20 hours on the Vanilla RootBox JB ROM. YMMV. I also had terrible battery life on the stock ROM and every other one I tried. This is the first ROM that's bested 10 hours. Again, YMMV.

what rom are you on? tw? cm?

Have you used Better Battery Stats? Or the JB release candidate GB08?

Not to raise the dead, I've just been busy, but this is still an issue for me. I upgraded to JB GB27, and I love the GUI, it’s such a step up from ICS. But I’m still getting **** for battery life. Yes if I use DS Battery Saver it works and I get good battery life. However all those programs cause flaky restart issues. The phone will just restart for no reason. More importantly it’s not getting at the root of the problem.
IRL I’m a computer tech and I can’t just let this go, as previously stated I’m tired of being shackled to the phone charger. I’ve swapped in a new battery, it’s not the battery. I even turned on the setting “Keep WiFi On > Only when plugged in”. That did improve the battery a little, but I still can’t make it through the day without being charged. I’m on the phone maybe combined 30min of phone calls, 30 min checking email, and an hour or so of miscellaneous watching video etc. I know heavy users that are on their phones all day, or let their kids watch Disney movies all night. I’m not that guy, I’ve had numerous cell phones and never have I had one that couldn’t hold a charge all day.
I will be diligent in monitoring this thread, please give me your troubleshooting tips and I’ll report back with the results.

Downlpaf betterbatterystats. And find the wakelocks.

Can do, will let you know at the end of the day.
EDIT: Actually I read multiple issues with SG2 and BetterBatteryStats. However your wakelock comment made me stumble onto the app Wakelock Detector. Again I'll run it and report back. Thanks for the point in the right direction.

Ive noticed no better or worse battery between being rooted/custom rom and stock not rooted. However my phone gets about 16 hours on average. My friend has an epic as well and gets only 10 hours. I feel as though it depends on the user and apps. Facebook is a silent killer. As is any app that uses backround. Best setup ive had so far is billgeryans Quattro Rom with ds and greenify. I pulled a whopping 25 hour minimal use before charge and 13 hour heavy use day.....

With titanium backup. You can also install greenify. It puts your apps in hibernation when your screen is off. So basically it's like freezing and unfreezing. Tbh I think it's better using greenify.

---------- Post added at 07:36 PM ---------- Previous post was at 07:32 PM ----------
so my 2 cents:
1) get a second battery and charger.
2) betterbatterystats to identify "bad" apps and either get rid of them or deal with them.
3) "autostarts" app to stop crap from auto starting on boot that you don't need running as a service.
4) dim screen! huge huge savings. keep it dim enough to use the phone.

Battery issues well I have a solution that won't solve but greatly helps. It's called greenify. It puts all running apps in hibernate mode. It's not like a task killer that just screws things up. U can choose what u want to hibernate and all that jazzy stuff. It's worth a shot. All in all if you want a bada$$ battery efficient rom go with wcx stock rooted rom. It's simply amazing. Hope I was at help

Check out greenify if you're rooted. It removes all currently unused apps and processes from memory, essentially putting them into deep sleep. That combined with ds battery saver and watching your wake locks will drastically improve battery life:beer:

[GUIDE] Insanely Better Battery Life When Idle - Battery Life Thread

UPDATE: Wanted to add from personal experience that these tricks all work on 4.4 KitKat ROMs. This information isn't stale
This guide should work for any Android phone running any ROM. (Though you do have to be rooted for most of these options. Nothing is THAT simple!)
The goal is to reduce your battery drain when your phone is idle. Nothing in this guide will improve your battery life when the phone is in use. But it will keep the battery from draining quickly (actually it will nearly keep it from draining at all) when the screen it off and the phone is not in use. And the battery savings can be extreme! As I write this guide my phone it has been 4 days, 15 hours, and 9 minutes since I last unplugged my Galaxy S4. I have 33% battery life remaining. You can have this too!
These fixes are not your typical "Lower screen brightness and delete carreir bloatware and disable auto syncing" tips. (Though all that stuff is still a good idea)
You can try all of these techniques or just some of them. Some of them will break features of your phone and might not be good options for you. Only you can decide if these fixes are right for you.
Special thanks for Mike216 and Penko956 for the endless research they did Greenifying, freezing, and disabling they did on just about every system and app on thier phone to see what all could be disabled. And to Torbitege who initially helped figure all this out with me for the HTC Sensation.
First off, what's using your battery?
If you're not already familiar with Better Battery Stats, fix that about yourself. Download it. Use it. Love it.
This app will run in the background constantly monitoring what's using your system resources 24 hours a day. It will tell you what apps are causing wakelocks, which are waking the device, etc etc etc.
The app won't do anything to help your battery life. But it will give you the information you need to adjust problematic apps.
Wakelocks and Battery Drain caused by Google Services
The battery saving impact is major.
This is my personal favorite battery saving technique. But it's not right for everyone, so read thoroughly.
Basically Google thinks your phone belongs to Google. Google Services runs A LOT even when you're not using the phone. This causes a ton of wakelocks and wake ups that use battery. I hate that. So I stopped it with a simple mod to the Google Services Framework.
Here's how....
This is a good old fashioned dirty fix, as it breaks some things. Most push notifications WILL NOT WORK AFTER DOING THIS!!!!! So this is not for everyone!!!! You've been warned. Please don't complain later in the thread that you aren't getting new mail or Twitter or whatever notifications after doing this. You're being told up front they will probably not work.
GTalk and GoogleNow (and maybe a few other things) will not work after doing this. Push notifications for any Google apps will also not work. They are casualties of the dirty fix. But if you're like me and never use GTalk or GNow this will help. Some other Google services might not work after this either. But if you're like me and the only Google service you use is the Play Store app, this will not affect you adversely. (Gmail and Google Maps run independantly of the Google Services framework and are not affected at all by this.)
Use this version of the fix for older Google Service Framework installs. You will know if you have a newer version if doing this install doesnt' prevent your wifi and data icons from turning blue (or whatever color your theme uses). If they turn blue, use the newer version below....
You need to download System Tuner from Google Play. The app will tell you to get Android Tuner instead. Don't do it. It doesn't have what you need. The icon is a blue suitcase with tools on it. Thats' the one you want.
First I froze GTalk and Gnow (Google Search). And no, you can't just freeze those two apps without touching the GSF. The GSF will still create wakelocks when trying to activate them even if they are not there. So you have to modify the GSF as well.
Go to System Tuner and select "Start Ups".
Then pick the Google Services Framework from the list and open it. You shoudl see a list of services.
Uncheck the things on the list below. (Basicall anything with GTalk or Checkin in the title)
gtalkservice.diagnostits.gtalkdiagnostics
gtalkservice.connection autherrordialog
talk.talkprovider
checkin.checinservices$reciever
checkin.checkinservices$triggerreciever
checkin.eventlogservices$receiver
gtalkservice.diagnostics.gtalkdiagnosticsbroadcast reciever
gtalkservice.serviceautostarter
gtalkservices.datamessagereciever
gtalkservice.sendxmppreciever
gtalkservices.packageinstalledreciever
gtalkservice.xmppendpointreciever
checkin.evenlogservice
gtalkservice.service.stalkservice
gtalkservice.pushmessagingregistar
You can freeze the GSF entirely with 1 easy step and that will also kill the wakelocks. But the Play Store becomes another casualty if you do that. Disabling the events above will stop the Google Services wakelocks dead in their tracks, and allow the Play Store to continue working. If you want to go that route you can do it but you'd have to unfreeze the GSF everytime you wanted to update an app.
Newer version if you have updated Google Service Framework.
Freeze the Google Services Framework entirely.
Profit.
Note: I haven't personally tried this and can't attest to it's viability to drawbacks. It was suggested by other members in this thread and confirmed to be working by several other people. Your miliage may vary.
One little quirk with both of the above versions is that when you turn on wifi or mobile data, the signal bars don't turn colors. They stay gray because you aren't connecting to the google servers anymore. (They normally change color to indicate that you are connected to the Google servers). After 1 day I stopped noticing they didn't change colors. Now it looks weird to me when I see them colored.
I highly recommend making a Nandroid backup before trying any of this. Once you go that, go nuts! You can't hurt too much when messing with the GSF because it will just shut down google elements. Worst case, you can always just reactivate everything, reboot, and it'll all work like it did before you messed with it. But if you accidentally disable Android System instead of Google Services, you will probably kill your ROM. So back a backup first.
And severely worst case, if you totally louse up your ROM, just restore the Nandroid and it'll all be back to normal in a flash. (Get it? In a 'flash'...haha I crack myself up)
The Greenify App Sollution
The battery saving impact is moderate.
This is one that you're just silly not to be doing.
Get the Greenify App from The Play Store
There is a free version. But its freakin' awesome so buy the donate version. It's $3 and the developer has more than earned it for the way he's making your phone awesome. (The donate version also includes some special experimental features. Read all about it. Do NOT just get the donate version. You need the free version too.)
This app basically lets your freeze any user app when you're not actively using it. And unfreeze it automatically when you want to open it again.
So if you have an app that likes to wake your device and run itself when you're not using the phone, you can just Greenify it and it will be prevented from using any system resources when you're not actively using the app.
You don't want to Greenify everything. Some apps need to run 24/7 like your messaing app, your phone app, etc. If you Greenify those you won't get messages or calls. The app is incredibly simple to us. You just select the app that's causing trouble and tell Greenify to 'go'. And it does the rest. It's just as easy to un-greenify an app if you greenify something you shouldn't have.
Not every app on your phone needs to be Greenified. Most apps behave themselves. Only do this to the ones that are showing as causing wakes or alarms or wakelocks in a battery monitor like Better Battery Stats.
Two that I will suggest for everyone to start with are Google Maps and T Mobile's My Account app. Both of these love to run when the phone is alseep.
If for whatever reason Greenify those apps hinders the way you use your phone, just ungreenify them! Simple as that.
Google Play Services and You
The battery saving impact is noticable.
Google Play Services wakes the phone a lot. It also does a lot. Read more about what all Google Play Services does here.
You have two options for this one. The first option is the nuclear option. Freeze Google Play Services outright. It will never bother you, but it might break some usefulness of other google apps.
The second option, thanks to XDA Member Karpfenhai , is to disable only certain aspects of the Google Play Services. This one uses the same technique mentioned above in the Google Services Framework Section, just different services to disable. (Thanks to Perseus71 for making me aware of this one and asking that it be included!) THIS HAS BEEN RECENTLY UPDATED
NEW PROBLEM AS OF MARCH 2015
The battery saving potential is ABSOLUTELY REQUIRED!
Since Google updated Play Services all hell has broken loose on custom roms. You get a persistent and unkillable wakelock for SystemUpdateManager.
The battery drain is horrendous. Your phone is awake and active 100% of the time.
This affects GPS version 7.0.97
I fixed this by going to the permissions manager (built into many aosp roms. If not available in your rom, consult yoir rom thread for ways to alter permissions) and disabling the permission in Google Play Services for "wake" and "keep awake".
Note: Some phones only show "keep awake". Just do that one if that is the case.
The problem is that on custom roms no ota is available. But Google tries to get it anyway. When it fails it doesn't shut down. It just keeps trying.
If the permissions method doesn't work, try this...

Just so you don't think I'm kidding around when I say you can severely increase your battery drain when idle, take a look at tehse screen shots from my Galaxy S4.
My specific set up is running CyanogenMod 10.1 nightlies with ChronicKernal. I haven't been using my phone much over the past 4 days. I have a total of 2 hours and 34 minutes screen on time and 40 minutes of phone calls during that period. So this is admittedly very light usage. But that's perfect to show you that these techniques really work to minimize battery drain when the phone is idle. And I promise you that your results will vary based on your ROM and Kernel.
This won't make the battery last longer during use. The screen will still burn a lot of battery and the cell radio does too. But if you want to make sure your phone will be charged when you need it without you having to carry a charger with you everywhere you go, these are the mods for you.
As you can see from these screen shots I am at 4 days, 16 hours, 50 minutes since unplugging. I have 31% battery left. (That's what the 31 in the upper left corner is. Thats' from an app called Big Battery Notifier. Its free on Play.)
The other screenshot is from Better Battery Stats showing my Alarms screen. Alarms are loosely the same as wakes. Everytime an app wakes the device (not neccessarily turning the screen on) it will record an alarm. If you look at your BBS alarms screen without these modifications I bet you see a lot more alarms than you see here, and keep in mind that mine screen show is showing 4 and a half days worth. Each one of those represents an app or service waking the device and using battery.

If the written instructions somehow baffle you, here's a video of the whole thing!

This will show you step by step how to do all of this.

Just a note. If you convert Google Play Services to a User App (TB), you can then Greenify (free ver.) it. This works very well and does not affect other functions that may rely on that app.
I also Greenify Maps and Google Search. Two more heavy drainers. Convert to User App first.
*Note: You must use Greenify v1.82 to Hibernate Google Play Services! Search this thread for links to it.
Fwiw, my sleep drainage is 0.3 - 0.4%hr, with wifi on 24/7.
I get either 7-8 days standby, or so far, 5.5 days with 3.5 hours screen time, or likely 6-7hrs screen time single day. Screen shots are in my posts.
I would argue too that these settings/tweaks do indeed increase your battery time, since while sleeping, the battery is draining at a much lower rate, therefore keeping more juice for live time use.
Although you and I don't use all of the same "tweaking" programs, we do seem to be on the same mission. Better battery life! :good:

It does. It also allows other functions to still work such as TTS. I had the issue a while back. Something to do with shared voice.
I also freeze Contacts and Calendar syncs as well. If I want them to sync I simply thaw them for a few seconds.

Btw. I forgot to mention that after I reboot the first thing I do is turn off Google Play in Running Programs. Persistent bugger. And of course I turn off notifications and auto update in GP as well with each new ROM install.
