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

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

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...

Sent from my SPH-L710 using xda app-developers app

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 %.

Wifi drain or just normal?

Hi,
New to the note 2, not new to being a flashaholic. Being very tame atm and only using stock rom (rooted) with no Cwm.
Strangely I get about 10% drain overnight. Got better batt app but doesn't really show much except wifi is/was on.. And this audio_out_2.
Is that normal on stock rom? On the dhd it was more like 1-2% on experimental roms

Disable stuff manually or use Juice Defender Ultimate (3.9.6). I use JD and never turn anything of manually.

I do have sync on. I guess what people are trying to say it's pretty standard on stock rom and I'm in need of an awesome custom rom to flash?
I used jd ages ago but configuring is a bit of a pain.. I may try it again till awesome roms comes out.

Check you applications, I have 90 apps installed and only have 0.5-0.6% per hour while sleeping with sync on.
Tonight, for example, I left wild blood downloading the last 200 mb it needed.
It took like 5 minutes, then I woke up and I noticed that it kept the device awake for 6 hours even after finishing the download, Battery went for 50 to 43% in 6 hours..
Custom roms won't make a great difference.. Maybe removing some bloatware will do, but you can stay on stock imho.

Just a question, do you, by any chance, have SIM plugged in? I observed quite higher power drain (overnight) when I did not have SIM inside.

Yeah, I have sim in at all times.. Erm apps wise, I've not added any new ones before my upgrade so I guess if there is an issue it would be some bloat apps? I tried to freeze as many as I dare using tb. (well, I followed the script of apps to delete on the other thread).
What app did you used to find what apps drained x amount per hr? That seems like a clever one
Sent from my GT-N7105 using Tapatalk 2

Yeah, I have similar experiences. My phone drains around 10% overnight with no apps in the background and wifi off.
So what I'm doing and it seems that it has marginally helped is:
1. Turn off Sync
2. Turn off Notifications from Email accounts as these come in all the time even overnight and the notification process and the Blue LED will drain the battery
3. Decrease screen brightness to around 40%
4. Turn on wifi only when needed
5. Disable some of the apps I don't use (Chaton, Yahoo Finance and Yahoo news, S Suggest and Samsung Store, etc)
Now I get about of 1 1/2 day of regular use.

Think I found the culprit..
Has anyone got motion feature turned on? There's that sneak wake function ticked on mine as default, I switched that off and I only got 4% drain overnight.
Perhaps others may want to give this a go and see if it helps?

4-5% per night is what I see on my GT-N7100 (intl), with Wifi on, BT off, GPS off, NFC off, Sync on.
I got Motion on though, with following features: "Tilt to zoom", "Palm swipe to capture", "Palm touch to mute/pause". I am not sure which one is supposed to be "sneak wake" one .
But now, when thinking about it, I realize I do not need any of those, so I am going to turn Motion off completely to see if it has any impact.

Best battery saver apps for nexus 4

Hi All,
I would like to invite your suggestions on best battery saving apps that you are using and how much difference does it make. Is it worth paying for apps juice defender ultimate or so http://forum.xda-developers.com/images/icons/advanced/battery_full.png
I am on stock (rooted) 4.2.1 and stock rom.
Thanks!

Best battery saver is your self. These apps don't work any better than you doing the things it does manually. If its using resources which they all do to "save" you battery... Its not really saving you battery.. But in fact using it.
Some tips I suggest:
Turn sync off in everything. Go to data usage hit the menu button and uncheck auto sync data. Also you will want to open apps that have notifications and make sure they aren't syncing either.
Remove maps if you don't use it or disable it at the very least this will keep it from polling your location and wake locking the device.
Keep your running apps to a minimum and force stop any unnecessary apps.
Turn off Google backup services. Sometimes this will be pulling and pushing data wake locking the device and using battery. I've never found it necessary especially since I use TiBu anyways for my apps to restore. It never saves my WiFi password either.

This isn't particularly good advice in my opinion. Are there apps that do use battery power when you don't force close them? Yes, sure, but many don't. And those which do without a good reason.. try to find a replacement.
Force closing apps all the time especially on a device with lots of ram will mean that your device has to restart the app completely if you open it again, which takes time and energy.
edit:
Also, turning off sync doesn't really help that much if you still use your apps often but instead refresh manually with the screen on, I'd expect. Of course everyone can decide for themselves, but one of the reasons I own a smartphone is because it can notify of an incoming email or something without me having to go to gmail.com manually. It all very much depends on what you want from your phone and how much you are willing to compromise. Using an App like Lux for example could also save you some battery depending on how bright you need your screen to be etc. There are so many variables to this.

Best battery saver is to not run crappy battery hogging apps like juice defender.
Turn on auto brightness, check your apps and make sure you are not syncing very often unless you need it. For most apps you can turn off auto sync and probably sync manually. I just turn on auto sync for handful of important apps which I open regularly.

Manually turn down screen brightness, don't leave the Wifi or bluetooth on when you're not connected, make sure apps you install aren't keeping the phone awake. Not much else actually works in the real world.

I get two and a half days from my Nexus 4 battery, I can thank Juice Defender Ultimate for a large part of that.
I could do all the tricks that Juice Defender does manually, but it would be a PITA and I'm sure I'd forget some of those tricks.
Better to pay a few quid, take a little time to set up Juice Defender, then sit back and enjoy your doubled battery life.

the best part of Juice Defender was turning off Wifi when not at home.. if you like this feature, search the playstore for 'Y5 Battery Saver'. It does the same thing, is simple and free..
Note: dont backup and restore it in titanium though. If you rebuild, install from the playstore. I have found it doesn't work right if restored

IMO if all you want is bt/wifi to toggle when you aren't home spend $5 on a few nfc stickers and stick one by your front door. You could also go with tasker.
As for battery life, francos kernel is giving me 2 days of battery (far more than I need) with wifi/bt on, whatever apps need to sync do so and I have brightness set to auto.

I found juice defender good for phones that are bloated with crapware and not rooted. It hurt battery life when i used it for phones with custom roms and kernels.

After I turned 'Google location' and NFC off, this thing can easily last the day with average use. Before that it was just draining like crazy.
Sent from my Nexus 4 using xda app-developers app

I've had juice defender ultimate since my Nexus S days. I wouldn't be without it as I can't get my battery to last a full day without it. When it's fully configured correctly, it works fantastic. I especially like that I can configure wifi to turn on and off automatically in areas where I have a saved wifi. I can decide the interval I choose for syncing data, and there are many other features. I'm not going to be manually turning on and off functions all the time, all that does is create more screen on time and is a waste of my time.
Bottom line, for me juice defender ultimate works because I spent time configuring it properly for my usage.

1.5 hrs screen on, 1.5hrs on call...I got close to 6hrs screen on when I did a drain test.
And no, I wasn't getting 2 days out of the phone stock with the same usage, it was more like 12-18hrs.

I tried using Juice Defender on a different phone and all it did was make the phone buggy with problems with wifi connectivity and other minor irritations and I could never configure it in such a way that didn't give me problems.
Are you having trouble making it through the day on one charge? I don't think I could use my N4 that much if I tried, I sat in a doctor's office the other day for 2.5 hours listening to Pandora on a bluetooth headset while reading a book with the screen on and still made it until I turned in for the night. Perhaps it is the Trinity kernel or custom ROM I am running, I never ran my phone stock so I don't have anything to compare with. I guess some of you want to go longer than 24 hours but it would be a really bizarre situation for me to need to do that.

So I tried juice defender ultimate and it did significantly increased my battery life. I am now getting about 30 hours or more with my regular usage. Even right now I have 63% remaining battery with 1 hour screen time and 17 hours total run time, see screenshot for usage.

[Q] Relatively unfair battery drain issue (Running stock JB 4.1.2 XXDLL4)

Or so I've come to believe it's unfair anyway, I just don't get how some people achieve 19+ hours or so on battery life, with 'heavy' usage as well like they claim.
I have posted some battery usage screenshots if it might be of any help.
When I was using the phone out of the box with an earlier stock firmware, it was the same as of now, even after my current XXDLL4 update. I always kill background apps, from ram and from running tasks, turn GPS off and other unused features, e.g. NFC, S beam, you name it. Like for example with these screenshots, I was using the phone moderately all day, a bit of browsing, some phone calls and a few games. Is 3 hours of screen time supposed to be normal with this battery reading? I don't get it Is there anything I can do to get these long hour performances on battery that everyone else seems to be getting with their note 2?

Im on stock unrooted 4.1.2 rom. Battery life was decent until I went to settings, application manger and then to all and disabled apps that I don't use including some widgets. Eg Simple alarm, learning hub, remote controls, Samsung sync etc and battery is significantly better.
With Whatsapp and Facebook running on the back ground all the time. .. I still manage to get 6hrs screen time.
However you must understand battery life is very much subjective to your signal strength, usage and the apps running in the background. Generally 4 to 5hrs on screen time with heavy usage such as 3d gaming etc is considered pretty good.
As long your phone can get through the day with a single charge, I would say that's good enough and enjoy every features of the phone without worrying about battery life
Hope I helped.

Are u able to identify what are the apps constantly running in your background?
I highly suggest u to do these few things for now.
1) update your rom to the latest 4.1.2 rom provided in your country. Go to settings, about device and go to software update or download Samsung kies, connect your phone to samsung kies if you have the latest stock rom.
2) Turn off sync.
3) Run through all your apps settings and phone settings. Turn off unneeded notifications
4) Go to application manager, scroll to all and disable whatever stuff you dont use. If it breaks something, just re enable it.
5) After all of above, go to application manager again, scroll to running applications and see what is running in your phone background.
6) if you have problems with media scan, go to application manager. Scroll to all and clear cache of the following apps. Download provider, downloads, media storage, gallery and drm protected storage and reboot the phone.
Another small tip is I diabled google search, Dropbox, disabled online search under contact settings, disable sync with wifi in gallery settings, disabled talkback, turn off all notifications in google plus settings. Turned off Facebook notofications and auto update.
Let us know if it works for u

I think your stats are okay. Because you're using H+. If you switch to 2G you'll see massive gain in backup.
Besides, 4.1.2 literally killed 15-20% backup from 4.1.1, don't know what was ****ing point, but Samsung did it! Just keep monitoring via Better Battery Stats, which apps/process are causing wakelocks, and then do the needful.
'Swyped' from my GT-N7100

It seems like there is too much wakelocks, judging by your stats. You are not rooted, right? If so, it's impossible to diagnose the wakelocks without simply guessing and eliminating which app is causing them.
The maps wakelock caused by Google now, along with AudioOut_2 and media scanner are among the most dire. The first can be "fixed" by disabling location services.

Just for your information. Your battery performance really below par which note 2 it should be.
2hours plus on screen time and 10 hours operating time left 5% was totally unacceptable.
With super heavy use, note2 at least must be able to last 10hours++ with 3.5 hours on screen with 20% left.

[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.

Get a new battery?

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.....

So how do you stop it? Do you just have to close out of every app before you set your phone down?

exiting apps don't stop them. you can freeze and unfreeze them.

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.

titanium can and you can create a widget to do it easily per app.
or
app-quarantine in playstore
or what I do:
shell commands usind connectbot widgets with a command like this:
pm disable-user com.facebook.katana
pm enable com.facebook.katana

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:

Okay so does Greenify do this freeze automatically, the interface is a little clumsy. I appreciate all the help guys.
