Anyone else having partial wakelocks/worse battery life after JB OTA?

Just wanted to throw this out there and see if anyone happens to be getting a lot of partial wakelocks without screen on or if your overall battery life has decreased since installing the 4.1.1 OTA. When I first purchased the phone, I had very very few incidents under my battery info where I would have a session awake without the screen on. Post update, seems like I've got a ton of really small wakes with no screen activity. I have turned off Google Now and every GPS/Location setting I could find. Downloaded Better Battery Stats today so I'm going to see if I can get some better info on what's going on, new to the program though and I don't understand most of the info that it reads.
Prior to the update, letting my phone sit overnight I would maybe see a 3 or 4% drop over the course of say six or seven hours. Now I'm seeing a 3 to 4% drop in battery per hour, more if I'm actively using the phone. I'm going to do more testing, specifically overnight to see how it fairs. Just wanted to throw this out there and see if anyone else is experiencing any of these issues.

I am noticing the same thing. Don't know the cause. Keep sync off all day.

Im getting the fast dormancy symptom again... no matter what i tried I cant fix it... always connecting as HSPDA+ even if im not using......anyone got any ideas?

Hmm, might try a factory reset and not installing any apps at all and seeing how it fairs. By chance, do you guys have any of the stock bloatware apps disabled? Not rooted/Frozen, but just disabled via the apps menu? Wondering if perhaps disabling any of them might be a trigger.

for me freezing modem fast dormancy monitor and modem stats service appears to fix fast dormancy

Yes I am noticing it to. I disabled Google now and it got a bit better.

Yea i'm getting that. I'm using 13% overnight now vs like 4% before. Not sure about the wakelocks though.
Some random things I've noticed are the blur widget resets itself alot. And the transition to the settings window on the left is laggy. How would one revert back to ICS? Google Now is not that worth it to me and the phone was smooth enough before. I'd take the battery life over the new features.
I did buy a second Razr M for my girlfriend that's still on ICS. I guess I can do a side by side compare this weekend.

I am loving the update.. only issue so far is fire fox crashing..no battery issues. Must be settings guys..

i don't think it is setting i have all my syncs to manual, and i have been noticing a lot worse battery life since the update i would have 18+ hours or so off charger with pretty heavy texting / game / some voice calls. Now i'm not getting close to that. I just disabled the fast dormancy service to see if that helps any, ill post back results

Just did a factory reset today, I'm not going to disable any of the bloatware this time, and I only installed BetterBatteryStats as well as updated all the default apps in the Play Store. Going to see if I get any wakelocks this time around.
Last night, after a period of 6 hours, I had over an hours worth of partial wakelocks from AlarmManager (subheading Phone).
-Matt :good:

I disabled Google Now and my phone used 7% battery over 6 and a half hours. A little bit better.

A factory reset (annoying as it is) helped me considerably. My phone was also seriously laggy before the reset...slow like my old DX on GB, much worse than factory ICS. It finally feels smooth now, like JB should.
Still seeing a lot more wakelocks than on ICS, but it doesn't seem to be draining the battery like it was before the reset. I also removed or disabled a couple of apps that seemed to be serious offenders (Accuweather was one).

Did a reset on mine as well and did not restore from Google backup. Still seeing wakelocks, but as someone noted earlier they don't seem to be draining the battery too much. With that said, the battery does still seem to tick down much faster than on ICS. One thing I did find that helped, although honestly it's not really a solution, is turning off data use when I'm out and about just answering texts and such. If I have data/wifi disabled, I'm getting closer to the battery life that ICS was giving, but then again who wants to go around having to toggle data on and off every time you want to look something up.

Is maps showing up on your battery stats and you're not using it? If so, simply open the application. It should say "updated to the latest version" or something like that. If this is happening, this will solve your battery problems.
Happened on my Galaxy Nexus and was happening initially for this phone too. Hope this helps someone.

Modem Fast Dormancy Monitor Service Not Responding.
Me and my wife both updated to KitKat on our Razr M's. I like it so far. The pop up about modem fast dormancy bothers both of use. When you look under battery, it uses more battery than other apps. I force stop it, reboot and it comes right back. A chat on Motorola web site sugested to wipe partition cache. The link that was provide gives the wrong instructions. KitKat using the power and volume keys has changed. They forgot to tell some people. That didn't work! I sent a long email to Motorola telling them that someone messed up or they did this for a reason! I guess if you get mad enough you'll just buy a newer phone. If that one thing is fixed, we would both be happy. The white background in text take some getting use to also. I hope Motorola will help us, but I kind of think Razr M's will be considered OLD! They are betting we will junk them for a new model.

[Q] Battery life is turrible

So, I got a Galaxy S4 back at the beginning of December, and the battery life has just been awful since I got it. I'm talking 5 hours max.. of juice. Its bugging me because I have tried so many different options and nothing makes it last any longer. One time I got 8 hours and I was like planning on throwing a parade because it was so groundbreaking for my GS4.
Here's what I normally have going on:
Admittedly I use my phone quite a bit and it's always on full brightness because hey its a $600 1080p phone so I want to be able to use it to its full potential.
I do not have one game installed. Never been a huge fan of mobile gaming.
I usually have a 4-5 bar 4G signal and barely use my wifi because it's like 300kb/s down.. And really spotty.
I may listen to 30 minutes of music a day.
Most of the time I'm on twitter and looking up stuff on Chrome.
This is not a battery issue I do not believe because my brother got the same phone and he has had similar issues. My brother uses his phone maybe half the time I do, so I doubt it is my usage that is bringing it down. I seriously do not want to have to contact Samsung for them to tell me it probably has water damage and then ask me to wait 2 weeks to get my phone back. My phone does tend to get warm from time to time but I've seen multiple reports of that. My iPhone 4 that I upgraded got 8 or 9 hours of battery life on similar use. (Android rocks)
So what is the problem?
P. S. my phone ran down 8% while typing this.

Are you running a custom or stock rom? And are you rooted?

Look at your battery usage in settings. Screen should be number 1. What's after that? Get betterbatterystats and see where your wake locks are. Without some additional info it's hard to help you

No I am not rooted anymore. My phone had a locked bootloader so I just uninstalled some bloatware and unrooted. I have had the problems since I got it.

It depends on what I am using the most. Most of the time its below 10% of total battery use. I would say it is mostly Chrome at 4-8%.
Right now it has been on for 37 minutes and is at 85% battery.
84% screen
7% Chrome

so under battery usage it's just screen and chrome usually ? (iId dump chrome to begin with anyway)
Is GPS on ? Any other apps that would be constantly syncing like facebook, twitter, etc ?

Yes, normally screen and chrome are the biggest consumers but I do use a few more apps. I've been wanting a Chrome alternative, but nothing I've tried has been as efficient.
I do use Twitter and Facebook(rarely), but at the same time, my brother doesn't use any social media and his battery isn't much better.

The biggest user of battery would be the screen, LTE, and GPS or location based processes. Honestly LTE that doesn't use much unless you are streaming all the time. Something isn't letting you phone go to sleep and if you can root I would just do it to be able to use an app like greenify or another wakelock killer that lets you keep apps from keeping you phone awake. Also turning off sync in general helps i.e making you refresh stuff manually.

Thanks for your help so by the way. I always have gps off and I only get regular 4G in my area. I will check with Facebook and try to turn off automatic syncing. Rooting is an option, last time I went through kingo and did it just fine until I tried to flash Cm over my locked bootloader *facepalm* Haha. I haven't heard anything definitive on the downside of using that tool. It was very simple. Would you suggest me going that route for Greenway?

No problem just hit the thank button
I'd root and just leave it stock the rest of the way. With battery life it's always YMMV. The battery stats given in the setting menu don't tell you much so apps like wakelock detector or Greenify allow you to stop apps from "waking" the device all the time to either push notifications, sysnc, do whatever crap they do in the background. You could also get something called better battery stats, the app in on xda just google it, and let it run from full charge to dead and then take some screenshots of partial wake locks, how often CPU is in deep sleep etc and others can help sort some out.
Just root with Kingo as its easy and leave the custom rom's alone haha.
BTW how did you fix the brick form flashing a custom rom on MK2 ? I'm on the good MDL firmware so not sure how others fixed the MK2 brick

Well after about a zillion tries on Google I finally found where someone got out of soft brick. It was something like hold down volume down, home, and power buttons until two options come up after you first power on the device. They are like "proceed to recovery mode" or "boot regularly" (something close to those anyways) and then you hit the volume down key to select boot regular and it boots up the phone without seeing that Oden screen. I was so relieved, I had already BSed my chat with a Samsung rep so they probably would have fixed it do to "accidental" downloads caused my phone to brick.

Watch out having your brightness to 100%. My statusbar got burnt into my phone. Just be careful. I can see the clock numbers(blurry) as well as battery and such. It sucks.

[Q] ANDROID IS JUNK! (Battery "life")

Every time I track down what is sucking my battery Google come up with a new way for Android to suck even more. I have sorted out various apps, location services, underclocking, etc. Now I find that when there is an update waiting the Play Store punishes me by sucking the juice out of the battery - even though I have it set to automatic updates and to give me notifications if there are updates waiting. No notifications and sometimes the waiting update doesn't even show up in My Apps, unless you switch to the Store Home and then back to My Apps. It might make a little bit of sense if these app updates were waiting for you to approve a change to the permissions but that isn't the case.
I have this problem on my Nexus 4 running rooted stock Android 4.4.4 AND on my waterproof Moto Defy+ running uprooted stock 2.3, so I'm guessing it is the Play Store which is junk. Does anybody know a solution to this? Please? I have tried searching for solutions but there are SO many battery/Android OS problems that I haven't been able to find the answer for this particular one.
I'm almost tempted to go for an iPhone - except that they are junk too. Maybe my next phone should be a Nokia 3310.
(BTW "junk" wasn't the word I originally used)

You're never going to get zero percent battery use, maybe your expectations are out of line?
How much screen on time do you out of a full charge? And what's your %/hour drop when the phone is sitting untouched?

google doesnt come up with a new way for android to suck more battery , YOU DO , note the keyword is YOU , now figure it out .

I was getting under 2% per hour drain then, without me making any changes, when updates came along and Android didn't tell me and Android decided to suck my battery it goes to something like 10% per hour

battery life is all dependent on YOUR personal usage, your personal setup, your personal decision to install whatever apps, and very much your phone/data signal. if your data/phone signal is only so so, then youyr battery life will only be so so. if you have things draining your battery besides for your signal and use, its up to you to figure out why. thye battery klife of my nexus 4 and nexus 5, actually, all androids that ive ever owned, has been wonderful. i get the same google apps updates as you, no less. so you have to figure it out.

OK, so as I said previously, with no changes made by Me I am finding that when app updates come along my Nexus doesn't alert me to the need to update but if I don't spot that an update is needed "Android OS" usage climbs and drains my battery until I look for an app update and update it. This is without loading any new apps and with the good signal I always have and all the things I normally have turned off (wifi, BT, location history, Google Now, etc) and slightly underclocked (1.2 GHz).
I'm sorry if criticising Android has offended people but I'm asking if anyone can help me solve yet another battery drain. Assuming that I'm doing something wrong isn't helping unless you can point me at what I'm doing wrong. All I am seeing is that I've sorted out all the known battery drains in my personal set up and yet updates, over which I have no apparent control, are causing another drain. I would like to hear from anyone who might be able to help and I apologise to anyone who is offended that I see an imperfection in the phone we have all chosen.
Thanks in anticipation.

You need to find out what's causing the battery drain. Get gsam or betterbatterystats. Without one of those you're just guessing.

App updates come along. Play Store is set to give notifications and to auto-update. Some app updates don't give notifications and "Android OS" causes a load of wakelocks until I spot that the update needs doing and do it manually. Same thing happens on my wife's stock Nexus 4. We are both in the Uk on Three network and have good signal.
I have BBS but I need to see what it says when I get this app update problem. I will post my findings when I get the info. If nobody here recognises this problem maybe I need to look at what is similar between our two Nexus 4s. I know we both have WhatsApp and, of course, all the Google apps, both on 4.4.4 but there the similarities end.

Why don't you try a ROM other than stock? I have flashed countless phones and tuned ROMs always offer better battery life. I don't understand why people go through all the effort of rooting then stick with stock ROMs. I know the general consensus is that the stock ROM (on the Nexus anyway) is one of the best, but let me tell you the general consensus is wrong. It is good, but there are much better custom ROMs.
Oh, and stock 2.3 on the Defy??? Come on man, why are you on XDA? This isn't the Carphone Warehouse helpdesk.
Try something barebones - no bloatware/small rom and choose barebones GAPPS. This will make a huge difference in battery life before you even dive in and stark tweaking further.

You're wrong. The rom will make very little difference. I constantly get far over 5 hours sot with stock rom and kernel. It's your signal quality and the apps you use and how you set then up that makes the difference

one more thing, you do not need root or to be rooted to run a custom rom or kernel. the only thing that root is need for is to change system files or to run root apps. but yea, you can get great battery life on stock.

I have been getting great battery life from the stock ROM after a few tweaks apart from this problem with updates. I have had a couple of other ROMs on this phone but went back to stock after the last couple of system updates. When I'm not having this particular battery drain then, if I leave the phone alone, I'm getting about 1%/hr battery drain. Also my wife doesn't want her Nexus "messed about with" and it helps if the two are fairly similar. Xposed is the big difference between the two.
The Defy+ is on 2.3 because I only use it when I'm out hiking and it might rain. The Defy is not easy to upgrade and 2.3 was where Android got good, so I'm OK with it, if that's all right with you.

BTW I have a degree in Electronics & Physics plus 17 years postgraduate experience in software engineering in the defence sector. So it's not that I'm not technical I just choose not to make a hobby out of keeping my phones working.

i see 5h sot nearly every day i use n4, so its not impossible. its a matter of your signal quality and usage. when im using LTE, i always se 5h sot. on hspa+, i see 4-4.5h sot. i have everything enabled and am a heavy user, plus have 96 apps installed. no facebook on any of my devices though. and i never ever disable data.

You're wrong. The rom will make very little difference. I constantly get far over 5 hours sot with stock rom and kernel. It's your signal quality and the apps you use and how you set then up that makes the difference

A stripped down ROM running only the bare minimum can greatly improve battery life! Just have a sift through some custom ROMs and you will find the ones that are tuned to do such a thing.
Also in reply to others here, the advantage of being rooted means you can remove unwanted system apps, underclock etc which if you're concerned about battery life would be quite important I would have thought.

You need to find out what's causing the battery drain. Get gsam or betterbatterystats. Without one of those you're just guessing.

This is what you need to do if you want to persist with the stock ROM. I personally have used betterbatterystats with success. Use this to check wakelocks as these are often the cause of mystery battery drain. There is an old but useful guide to that here: http://forum.xda-developers.com/showthread.php?t=1827676

Not possible with the 2100mah that n4 has! I have the same set up and I'm getting 3h sot..

i never use data and i average 3,5-4h sot?

UPDATED! FIX: improve standby drain! (not sure if exynos only?)

So I would like this tip to be there for as many people as possible and not let it get lost in some thread. Already got some great feedback from other who tried this too.
I do not have any feedback yet from snapdragon users, so results could be different there
In settings ==> apps==> show system apps.
Disable and then enable the following:
- Google Services Framework
- Google play store
- Google Play services (here, only wipe all data en cache).
After you enabled it, these services will update themselves again in a few minutes. But with one big change: a great standby battery usage!
UPDATE!
So it seems I had forgotten some other settings that I changed also, until I read someone else his post. So for here some additional steps:
- privacy -> location -> increase precision: set wifi en bluetooth off
- privacy -> location> location history: remove location history, and turn all other devices other then THIS DEVICE, to off.
After doing all steps, do a restart. Just to be sure .
Let me know if it helped you too

Just did it, will report back with results

What i did last night was disable it that 3 and go to bed and charge the phone and this morning i turn in the 4G to go to work , and what i notice was the battery last i bit more , i notice the difference.
But as we know we can live without google services.
Now i see google services is one of the problem.
The standby only at night i can tell something.

Already losing only 2% battery overnight on wifi lol

How do I wipe the cache here? Also no option to disable or even stop here.

Nevermind I figured it out.

Unfortunately, this didn't help me. I'm still losing ~2% / hour, even overnight on WiFi.

Did you enable Google backup? Just trying to find out why it works. It's the only thing I have disabled while using this trick.

I have had Google backup disabled prior. Battery life still miserable. Did this trick seeing how it works.

This is where I am at now. I don't think this solution had any impact on my battery life. I was able to achieve these kinds of stats day one of the upgrade on tmobile with APG1 FIRMWARE. prior to that update less than 4 hours SOT. Where I'm at now isn't terrible, but it certainly could be better

well this is a great SOT for a mix usage..... I will test this method tonight and I will comeback tomorrow with the solution I used for the past week.

You're saying my stats are great? I have GPS toggled off and Google back up disabled. I think battery life largely depends on what you're doing. Seems like you get much more life out of watching YouTube versus texting, or something similar. Also, no wifi usage today.

I'm assuming you're referencing the WiFi glitch you noted on your device? In that case I generally don't use wifi much. Even when I'm at home I just never think to turn it on. I'm a nurse, so at work I'm moving around and jumping from modem to modem, plus all lines are monitored and I just feel uncomfortable with that. There is one unsecured connection which happens to be where my office is located, but like I said I bounce around at work a lot.

While I never thought I would see the day that I was able to achieve 6 hours SOT, somehow I did. I'm attributing it mostly to the most recent Tmobile update although I did follow the instructions in this video, but based upon previous usage drain prior to applying this method, it seems to be on par.
Granted I do have location services turned off as well as Google back up, which has not been of any help historically. So with that being said I am finally pleased with the battery life I managed to achieved. However I will continue to monitor it as battery drain on this phone just seems so day to day.

nevermind. Happy it helped

Only get ~2 hours of on screen time - "Android System" battery drain

I am on the latest 7.0 beta, T-Mobile version, I am getting pretty frustrated. I only get ~2 hours of on screen time. Right now at 30% and Android System has used 1350 mAh and CPU total is close to 5 hours.
Attached some pictures from yesterday and basically the same exact thing - maybe one of the packages listed is killing the battery?
I know there are a lot of posts about this issue but nothing that I've found useful unfortunatlely.

Did you try a factory reset? That help me get good battery life.

Been thinking about doing that, but not sure why it got really bad all of a sudden. I could get 3 to 4 hours before.
I think I'll wait until the official release is out and then do a reset - hopefully it comes out soon.

Still on 6.0.1 & Android System is my #1 battery drainer.

I am getting pretty fed up. Thought the new updates would make it better but no go for me.

If only you got root, I strongly recommend using Myandroidtools/disable service. Samsung roms sucks pretty bad, I have never ever experienced something like battery drain on other phones. Since I disabled 80+ Google Services and some samsung bloat, android system takes about 2-4% drain after a whole day. I am using Renovate on nougat.

Looks like a lot of you are very unlucky. My battery life is superb! At the end of the day I still have ~35% battery remaining. I recharge every night regardless of how much battery I have left, so it does me just fine

I would strongly advise to stay away from any of those 'fancy' package disablers.
They do no good and often deteriate things. I have on average over 8hours SOT and never used disablers.
Most Samsung apps don't put any drain on the battery. It's things like Facebook etc that hog resources.

Yeah, if only i got Facebook apps installed. I have fully working locations, notifications and other stuff - most of services I disabled are feedbacks, silent loggers and stuff I dont need or use. Only corrupted app is Gmail - which I don't use.
I got sync switched on, lots of calls, auto brightness, voice assistant and usually get 5 hours SOT during my usage which isn't bad at all.

So not sure what did it, but I installed Greenify and also changed from 1080p to 1440p and I get about 3ish hours on screen time. Still terrible but will do for now.
My phone also feels faster after changing resolution back to 1440p. So weird.

I mean location. Aod takes almost 40% of battery in 24 hours.

I remember Samsung saying it only consumes a couple a percentage points.
This article tested and it's nowhere near 40%. And I use the phone about 15 hours before it gets charged again so it should have a huge impact.

Okay, stop reading useless news and try it by yourself. Phone dont go fully in doze mode with AOD on and keeps light and other sensors on like proximity to put more or less light in the aod screen. You are complaining about **** battery and I am telling you that I have tested how aod can take 40% of battery in one day. You really believe samsung? Come on...

I really don't think you're right as that's not my experience either. I cited the article because usually the tech websites have some experience - my anecdotal data, or yours, doesn't carry much weight.
As posted before, my screen time has increased and keeps going up. Got near 4 hours of on screen time today. Greenify must have killed a process that was putting the CPU on overdrive and which showed up under Android System. I shouldn't have to take the time to find fixes however since Samsung and the Doze feature should be doing this already.
I appreciate your advice, no need to get upset we're just having a discussion...

I don't really see a discussion in the fact that AOD uses a lot of battery if you keep it on all day, it's pretty much guaranteed that AOD is the main culprit. And your own experience with your phone and its settings is worth a lot more than the experiences from some tech website. Everyone's phone/settings is different.
