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

It looks exactly the same lol. Just one was running on battery longer than the other?

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,
El Mono

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 %.

I'v been using it for about a week. Continuously waking up the phone for sensing and checking apps and options was draining more battery than actual saving it. I wouldn't reccommend it at all.
Classic solutions like Greenify + Wakelock Detector work way better IMO.

I am yet unsure to how much does this improve the battery life, I've been using it for a month and giving it time to check. Although my device doesn't come out of deep sleep with it running, I kinda feel the battery drains a bit faster. Can't say that for sure but thats what I am feeling.
I will keep it up-to-date with you. Just did a full charge on airplane mode and I will be monitoring everything.

I'm telling you guys from my experience i have seen better battery, also MAKE SURE you go through the settings because there are settings such as WIFI Management (Automatically enables and disables WIFI during your day) which i dont need/use.
Also enable your Inactivity Power Boost option via your settings.

I've found it helpful but to be honest it wasn't a massive improvement, I found far better results when using Greenify.

Even I got massive battery drain. I wasn't using my phone at all. And in half an hour it reduced from 91-86 percent. Data/Wifi/Sync and everything off. Wake lock detector shows Battery guru woke the CPU most number of times.
I've tried this earlier and uninstalled it. I'm giving it another try. Its in learning process now. Let me see how it goes after two days.

So when you change your habits it will drain battery again; why bother?

I used it for about a week but decided to uninstall cause it always requires location services to run. I couldnt notice a difference as well. Grenify ftw!

You can also try DS Battery Saver, it also control my wi-fi, puts my phone in deep sleep mode that's mean no more background process and above all it doesn't require root..... And if you are rooted try one power guard, it's best battery saver....

Rapid Battery Drain - How can I improve?

My battery seems to be draining quite fast. I have removed a lot of bloatware, but I'm not getting the type of performance that others are getting.
It has lost 70% in 5 hours just doing a little browsing, watching a 20minute video and playing a game for half an hour. This was with Wifi on, and mobile data switched off, and background data switched off too.
I've had the device for a week now and I've charged it every day.
Any Ideas on how to improve it?

Could well be your brightness level? Are you using autobrightness or is it on a fixed level (I hope its not fixed at 100%!)
If you use autobrightness try using an app like LUX auto brightness instead.

Thanks for that, I did have it on Auto brightness for the first few days, but the last few days I switched it off just in case it was that, but the problem remained. I will try LUX auto as you suggested.

My guess is a corrupted media file somewhere which is causing your media server to prevent the phone from going into deep sleep. When you go to settings , battery, is media the no 1 juice sucker?

Why is Android system using up so much? I've even got location switched off and Google search etc. is deleted.

If 're not using Xposed Frameowrk for tweaks, looking into enabling ART - I did that and my battery life has been impressive.

I did try that, but it didn't work and the phone was a bit laggy. Why would android system take up 15% of whatever the battery uses? I'm getting so frustrated, I might do a factory reset.

How long has that screen been on for?

A shot in the dark:
Do you skype? Skype was draining the battery down in the Nexus 7 2013 even when you were not using it. I disabled it and the battery improved greatly.
Another option:
It sounds to me that there's an app that is draining the battery down a whole lot. I would try to isolate that app (by deleting each one you downloaded one at a time) until you have found it.

I don't have skype, but I like your idea - I've gotten rid of almost all the bloatware stuff. What I think I'll do now is charge it to max. DO a factory reset and not allow Google to start downloading all my apps again.
Funny thing though - when I charged it last night and unplugged it for 3 hours it only dropped a couple of percent. It started dying rapidly after I opened up a few other apps.
What I'll do now is charge do a factory reset, then switch it off, then charge to max before turning it on again. When I first got it, it turned on as soon as I plugged it in. did the same happen for everyone?

What you might want to do is download Greenify on the play store. This will tell you what apps are running in the background and then it will turn them off (hibernate).

Make sure that you leave the battery charging for about 10-15 minutes more after your cradle light turns green. Sometimes the battery isn't fully charged despite the cradle light turning green. 30 minutes on a game shouldn't be using that much battery consumption.
I usually get about 10-12 hours or more on each of my batteries ( video calling, chatting, games and my 4g is turned on 90% of the time

Stock OS

Been poking around here and reading all the posts that people had mentioning battery life on stock/cm11. Is battery life really that good? I find myself trying everything possible (including hardly using the device, turning brightness all the way down, turning off bluetooth & Dynamic perspective) and I find that my phone is dropping like a brick. I can have the phone lose %s in front of me just having the screen open for a few minutes doing nothing else.
I even have two apps to optimize/kill all other apps and I'm finding that this phone is dying faster than a t-mobile pre paid LG L90 I was using prior. I just don't see how people with stock and all the features on are getting more than 5 hours battery life tops. This phone dies while you use it on the charger, which is a first from any phone I've ever used.
How do your experiences stack up? Do I just have a bad unit? Really considering going to cm11 now (really wanted to like Fire OS).

You must have something wrong with the phone. I have had Samsung S3's and S4's and the Fire is far and away the best I have experienced for battery life. I am getting close on two days on a full charge although I do not use it a great deal for voice calls.

Are you keeping Dynamic perspective off with a low brightness instead of auto? Don't see how two days is possible unless you absolutely never used the device. I can lose like 10% an hour just on the browser reading text sites.

Fire has the best battery life of any android phone I've owned. I'm on fire os with a different launcher and I have dynamic perspective on (not for home screen obviously). I'm also using auto brightness. I'm rooted with gapps installed. I get great standby time and even in use its good. You should get gsam battery monitor and see what's going on, although I think you might have a broke unit.

Here is a picture from Gsam (I don't have my phone rooted). I think this is pretty bad for only 3:28hrs of screen on time and that was with the screen at the lowest brightness, not on auto. For app usage I have 7% coming from a game I was playing, but the rest of the drain is coming from system and kernel. Would really like to see another users stats with similar screen on time, as I'm pretty sure I could completely kill this phone's battery in 4-5 hours just using silk browser on Reddit.

Your phone isn't going into deep sleep. It's hard to determine exactly what's going on there but if you download kernel adiutor (yes, that's the spelling) you'll see its locked at 300mhz most of the time. I know it sounds crazy but have you rebooted? That can often sort out a misbehaving app. Are you rooted? If so deploy greenify.

5 hours of "screen on time" is solid, the combined time incl. standby, etc. is of course much longer. He didn't know how to interpret the statistics from the device, it was a misunderstanding.

That kernel app won't help battery life but it will show you how long you spend in deep sleep.
As for greenify, you should greenify all the Google apps. I actually greenify everything except sms app, browser, phone and alarm apps.
Also, this could possibly be some kind of location based frippery. Turn location services off or onto battery saving mode if only temporarily. And turn off auto sync if it's on.

Battery Drain

Ever since I updated to 8.1.0 with December security patch, I've noticed my battery draining faster than normal. I was getting 4-5 hours of SOT with around 45-50% battery left. This was after being off the charger for 12-16 hours. Now I'm getting about half the SOT at similar numbers. Anyone have any ideas?

Excuse my stating the obvious, but you need to find what process or app is using the battery. You should be able to get a rough idea just using the new features under Settings>>Battery. It will identify which apps are using the most juice. Run the phone in Safe Mode to see if your battery life goes back to normal. It could also be a service like Google Play Service which sometimes wigs out and starts chewing battery. Are you rooted? If you need more detailed information there are battery drain apps available to help isolate the problem (BBS and GSam). These apps require root to give the best results.

Not rooted and currently locked. I've downloaded GSAM and have adb permissions and it simply says things like Chrome, RCS Phone and Play services. If you see from the photos below you can see what I'm talking about. Chrome currently isn't that bad, but yesterday and the past couple days it's been like 9% or more of the battery.

Two things: I've never seen phone or kernel use that much battery. On one page phone usage is 33 seconds, yet it used 9% ? I think RCS is running the background all the time. See if you can toggle it to not run in the background under Settings>>Apps>. High kernel I'm guessing is a kernel wakelock or multiple. You've probably loaded app(s) that are creating the problem, but you need to find out which one is causing the wakelocks. There is a wakelock detector "lite" app that doesn't need root but I don't know how well it works. I know the root version works well. Lastly, on the first screenshot with the battery, scroll to the bottom of the page and see which apps are listed there. I'd be willing to bet if you ran the phone in Safe Mode, your battery drain would disappear, meaning your user apps are causing it.

Well in safe mode my drain is gone so I'm not sure which app is doing it, but to directly answer your question about the RCS it is an overall app meaning it is related to several Google play services. I'll upload a photo of it. I have to reboot into normal mode.
Edit: I'm wrong about that it was the play services.. I'll have to start uninstalling the apps to determine which one is draining the battery I guess.

RCS can be a real battery hog, but I don't know why. I don't have RCS on AT&T. Do you use Messages as your primary SMS? Open Settings>>Advanced and see if you can toggle off "Enhanced Features". Open properties and check if it is using battery optimization. If it is not, set Messages to battery optimization. You can always turn these back on later if the battery drain remains.

My battery life has been restored to pretty much the same as it was with 8.0. I also noticed poor battery life after installing the 8.1 update, even though they changed the way battery life is estimated with this update (supposedly). Something just felt off, but now everything feels great! I am fairly certain what changed is installing the Greenify Magisk module and/or the Google play services doze module (this enables battery optimization on the Google play services app). Not sure which one really made the difference because I installed them at the same time. However, there is definitely a major difference!!

In my experience that's really good.
Before 8.1 I noticed about 11% per hour during screen on use and about 0.33% per hour while on stand by in my pocket or a little bit better if it's just sitting on my night stand not moving while I'm sleeping (I think doze is more extreme in that situation) which seems to match what you are getting. Based on that screen shot I think that's like 8 hours screen on time over like 35 hours for a full charge. I've done a little bit better but not much. That's excellent battery life.
Since 8.1 it has dropped. Best now is maybe 7 to MAYBE 7.5 hours over maybe 26-28 hours. In my experience battery life always drops after an update but this case is far from the worst. I remember when my Nexus 5 updated from KitKat to Lollipop. The battery drop was awful and to make matters worse the battery life of the Nexus 5 was pretty bad to begin with.

So in my last reply I thought I was wrong about RCS Phone app being a conglomerate of several apps in the phone. For some reason I couldn't find the information I needed at that time. I wiped my phone and started over after posting this thread. I was trying to isolate the misbehaving app. I thought it might have been greenify actually, but no the drain has returned to a lesser extent though. Here's some photos of this RCS app from GSAM.

I'm not sure what is causing the drain at this point. I've installed Better Battery Stats to locate the wakelocks so I can ignore them through ADB.

Have you tried disabling RCS ? (Post #6). BBS is good for idle drain, active drain not so much. It's best run overnight without touching the phone for 8 hours or so. Pick the phone up in the morning and create/save a log file as quickly as possible. Post the log to the BBS thread if you need help deciphering.

I cannot disable it since it is comprised of multiple apps. You can see it in the pics on my last post.
