[Q] Anything to be done about wakelocks - Verizon Galaxy Note 4 Q&A, Help & Troubleshooting

So I was on 5.1.1 rooted for a few months and loved it. The battery life was great, and whenever it would get bad, I could find the wakelock that was causing it, and kill it. A couple of weeks ago, I tried to upgrade to 6.01 and ended up screwing up root on my phone. Despite many attempts to get it back, I was unable to. I finally gave up. Originally, I was going to keep the Note 4 for as long as it stayed alive. Now that I can't get root back, I will be moving on to something else. Not sure what it will be right now.
In the meantime, I have 6.01 on my phone and I hate it. I literally have three non-stock apps on my phone - Fitbit, RSA Token, and Package Disabler Pro. I used PDP to get rid of all of the bloatware crap that VZW and Samsung force on the phones, and left everything else alone. I have one gmail account that is checked. I shut off bluetooth and location. I unplugged my phone this morning and other than looking at a few email messages, I left it alone. Within four hours, the battery had gone down to 72%. Because this phone has no root, I literally have nothing to go on, except for the battery app on the phone. I looked at it and it had 10 minutes of screen on time. Other than that, it just had phone standby and android system. The app did show that the phone was pretty much awake the whole four hours. So somewhere, I have a nasty wakelock going on.
Anyone have any suggestions what might be going on, or how I might figure it out? Aside from the three apps that I've installed, it is 100 percent stock. I really miss having my phone rooted. I used to get days out of my battery. Now it barely lasts a whole day just sitting there unused.
I am so sick of Android and these stupid and impossible to troubleshoot wakelocks. I've been using Android since the Evo, and the only time it's been anything except a battery sucking nightmare experience is when I've been able to root my phone and take controls of it.

I think it's the 6.x firmware on the phone . laggy as hell. I've been using partial wake lock to keep it responsive which if course eats the battery. Verizon rep said a lot of ppl have been complaining about it. I've factory reset and cleared cache with little to no improvement .only 2.5 weeks until my note 8 arrives and cleared m done with this laggy phone

[Q] GN2 Battery Performance Degradation after Update

Hello
I have a AT&T Note2 that I got late November. Battery Performance was fabulous. I just recently got the update to 4.1.2 OTA and there was some sort of upgrade or maintenance just prior to the 4.1.2 update.
I immediately noticed a difference in battery performance. It was substantially less than what I had on 4.1.1. I cant get any straight answers from Samsung or AT&T, there is no comprehensive log for the update so its hard to figure out whats going on.
Same software load as on 4.1.1. I did notice that after the update to 4.1.2 there were substantially more items in manage apps> running than what was in 4.1.1.
Samsung claims the root cause is the update to the OS and a change to the wifi radio and software.
Does anyone know what really is going on. At&T is a lost cause and no help whatsoever.
Thank you
I will be interested what you find out as I am experienceing the same issue. I went from 95% to 65% overnight doing nothing (WiFi on). Earlier today I was losing about 2-3% battery every 15 minutes doing nothing and did some research. All I could find out was to turn off all location services and since I don't get Wifi at work, turn off WiFi while here. This helped some, but still would like to find out what is going on. My iphone was a battery hog in the end of its life and my new GN2 lasts barely as long as my 2 year old iphone did. Not a happy camper right now.

Hi, I'm hopeful one of the Senior Members or Mod's will run down a answer as well as a comprehensive change add-delete and enhancement log regarding the 4.1.2 update. All I can say is I have not added anything my daily use is the same..no games. I disabled all the att bloat wae other than hot spots. I sort of paid attention to my running apps in 4.1.1, and now in 4.1.2 there are many more things theree that wernt prior to this update. I didnt have to disable anything prior to this update.
The answer is not in disabling bloat apps. The answer is in the log that shows what was done with the update.
I hope someone can get that because it holds the key to the answers we are looking for.
Who knows maybe one of the developers will read this thread and be able to help.
try a battery pull and obviously reboot. Download the Gsam battery monitor from the market. I think it is free. It dumbs down a lot of stuff and pretty much tells you what is taking up your battery. It does a much better job than the stock battery checker. After an hour or so, the longer the better, it will show you some apps or processes that are the culprit.
Battery stats app is a paid app in the market but I think it is free on this xda site somewhere for members. That appears to be a very comprehensive battery monitoring apps with wakelocks and it gets very complicated for a novice such as myself.
can you provide additional details on your situation, for example:
what's your baseline comparison, e.g., before: 18 hrs use with 4 hours screen time, after 13 hours use 4 hours screen time
are you rooted (i suspect not)?
have you gone into Settings->Battery to see which apps, etc., are using your battery?
do you have a lot of music, pictures, etc on your phone?
not an answer to your question, but... have you considered performing a hard reset on your device and then testing battery life with at clean slate?
looking at your battery stats is a better indicator of what could be causing poor battery life. i'm on the same release as you and my battery life has been the same if not better. also download better battery stats to see if you have wake-lock issues. i'm averaging 16-20 hours per charge with 6-9 hours screen time, about 150 emails daily and 35-90 minutes in phone calls.
So yesterday at 19 hours of use (maybe 2 hours total of emails, web surfing, and using a couple apps, music for an hour at the gym) I still had 32% left. Not bad. However, my wifi was off all day, even at home, and I kept my location services turned off. So tomorrow I am going to test it with Wifi on at home and my location services and see what happens. The Gsam battery app i used yesterday was pretty cool although at first I wasn't sure because it said that the app was using 15%. But as the day progressed it never went over 4%. Still new to the android platform, but learning.

I APPRECIATE the response however I would like to know what was done with the 4.1.2 upgrade, what changed, enhanced or whatever as well as the AT&T maint just prior to the 4.1.2 upgrade. Nothing was disabled, I was runn8ng the same exact software load, same apps, no games, and wifi wS constantly on. While disabling bloatware, shutting down this and that, turning off wifi at this point is helpful, its not a acceptable answer as to what happened.
This forum has some of the most respected developers and computer genius's around. Whenever you ask for something and everyone else comes up empty, the first thing you hear is go to XDA.
My Galaxy Note2 had the most incredible battery time of any device I've ever owned prior to the updates. Im also pissed because I didnt even know that the red and grey arrows and the connecting to dnr server was AT&T doing a update. There was no forewarning.
The Note2 is still fabulous to me, I just want to understand what has happened and why. I am not asking for a say in what they did, certainly this is my phone, I believe that I should be entitled at least to know what transpired.
There should be no problem producing a comprehensive change log with a lay person level explanation.
I was getting 2 days off charger with 8 hours of screen time and suddenly the battery doesn't seem to charge past 50% and I didn't do a single thing to it but tonight I am cleaning everything out and starting fresh because something odd is going on

I think the key to many answers is 2 items.....a log and explanation of what occurred in simple terms regarding the 2 updates. There was a no warning automatic att update done just prior to and then the actual 4.1.2 update itself. My gut opinion is something was changed with wifi and how its handled along with some other software changes.
I feel like. Dog chasing my own tail...disable this, disable that...bull...nothing was disabled and wifi was always on prior the updates.

Battery Issue? Phone turning off for no reason...

Hey I have been noticing a weird issue with my phone.
Ive flashed a few different ROMS to see if it was a specific one or if it is something else. Yes, that didnt work.
I am still having random turn offs which shut the phone down. Whether on it or not it happens at least twice a day.
Does this have something to do with the battery? When i reboot the phone the battery level shows at what it was...
last example I had was 68%. So it wasnt fully dead. I was going to send my phone back but decided to stick it out and maybe a new
battery will work? Any help will be greatly appreciated.
Take your battery out and place it on a flat surface. Try to spin it. If it spins, it's time to replace it.

Try a stock rom for a few days if the battery seems fine. My phone has the sleep of death issue with various jellybean AOSP based Roms.

One thing I've noticed. My Battery will get extremely hot. I'll pull the battery, wait for 5 min, put the Battery back in and will be able to proceeded.
Just my $.02 worth
It's certainly the battery, only fix is to replace it.
Happens to me once every other day. Not a big problem just take out the battery and replace it back in.
I'm about to change the rom temporarily from goodness to blu kuban to see if it continues.
If it does then it has to be a battery issue at least on my end...

Battery issue with Galaxy SII
The shutdown issue seems to be inherent in many SII regardless of carrier. I have had this problem with my Sprint phone since new. It has been exchanged twice thus far but the problem continues. Samsung will tell you to do a factory reset. DONTdo it. It will not fix the problem.
It is NOT the battery in most cases.
It seems to be OS related. I have cleaned the battery contacts; not charged unless below 20%; unchecked the Power Saver and Optimization functions; and did a factory reset without loading in any additional apps for awhile. Nothing stopped it from shutting down.
I was able to prevent shutdown for about a two week period by not charging it until it went below 20%.
I did notice that my RAM consumption was over 60% prior to the phone acting up.
Could it be a memory issue?
Thus far, I have not received any real support from Samsung or Sprint. The Galaxy SII is one of the few phones that cannot be run through a diagnostc test by Sprint. If you have warranty coverage, they will replace it but I can almost guarantee the problem will beda plague to the new one.
If anyone has found a solution to this shutdown thing, I would love to know it. Right now, I check my phone status very often throughout the day to see whether it is one or not.

What rom/build are you on? Rooted?
Your problem isn't a common topic here unless your running experimental nightlys or doing a bad flash/install or your battery is no good.
I have two Epics since 10/2011 and have never encountered this condition. We did replace the batteries on both phones in 12/12 because of rapid discharges, going from 90% to 50% after a reboot or running a system heavy app like browser, camera, or YouTube.
Other than that all we do is use and charge when necessary.
Both phones are rooted, her phone is a workhorse because of her job, fashion design NYC, keeping track of 4 email accounts (2 gmail, 2 Microsoft Eexchange) plus crazy messaging all day long.
Check your phone model.
It may be different. Maybe you have the wrong battery in your phone?
There where some instances that had some Epic's with 1500 mha batteries instead of 1800mha!

Phone is not rooted....straight OS. I will check the battery to ascertain if it is a 1500 or 1800.
Phone is an SPHD710. It's only three months old and has been swapped twice by Sprint. I think it may be ICS. When I got it, they updated it to the latest OS which was ICS fron Gingerbread, so I don't know if it would have had the same problem with GB.
I'll try to get a new battery from them and see if it makes any difference.
Thanks.

Sounds like the power button might be going bad. If you are not getting sudden large drops or increases in battery % I would lean towards the power button.

I'm having the same sort of issues on my S2. I've had it for about 6-7 months and it's worked fine but the last few weeks it's been almost unusable. Within 5-10 minutes of using my phone it will shut off, regardless of the battery level. Turning it back on would show that it was critically low on battery and it would shut off again within seconds. Plugging it into a charger would let me turn on again and restore the battery level to what it was, oftentimes over 60%.
It seems that the false battery reports come and go, but the real problem is that the phone just keeps turning off. It's useless without a charger anymore. I've looked on Sprint's forums and it seems like many people have been having the same problem. Especially after the new JB update. I've been running stock so I figured I might try a custom rom. I rooted and went back to FF18 but I can't load up a custom recovery to install a ROM. The link to download the autoroot package in this thread is dead.
I have run into the same issue starting about three weeks ago. I am already on my second battery, which is only six months old, but it was behaving as if it was dying again, so I got another brand new one from the sprint store just to make sure... Phone was still shutting off though. After some more research, I came across someone who had a bad card reader in their phone. They even wrote a program that keeps track of mounts, ejects, and bad ejects. I downloaded it (its called sd card monitor), and sure enough, my card is ejecting itself multiple times an hour (which is no surprise, this phone has destroyed several cards already)... If I remove the card, I have no more problems... So for now, I am using my phone without a sd card. I am not paying Sprint $50 for a refurbished replacement at this point, I am fed up with their service and will be changing carriers after the S4 comes out...
The strange thing though, the sd card issue doesn't affect the phone if it's plugged in.

Can you confirm that your phone is having the same issues due to the card reader.?
If so please share.
(Otherwise you need a new battery.)

I ran that SD card monitor app for about 4 hours and no disconnects, so I guess it's a battery issue.

[Q] NEW LG G3 - Lags/Freezes Apps, Battery Drain...

I have had the G3 about 5 days now, after I had gotten my dream device, the Xperia Z3, and had several problems and bugs with it, sadly and reluctantly exchanged it for this one, because the S6 was on back-order, and Verizon would not let me wait to exchange the phone, as it would be about a month wait now...
My immediate issue is the LAG! I have had to uninstall 2 very beloved apps, because the G3 would sit on the loading screen forever and never do anything. I tried re-installing 3 times, no luck. This is my biggest issue so far.
Also, I am unhappy with the battery life. I have done most of the battery-saver settings, but because of bad eyesight I need the brightness turned up. I do watch videos but not too often, I don't really play games, I mostly just text, maybe make one call a day, and check FB for about half an hour a day. I have the screen off any other time, and my wifi is on so I can browse without using data. Which setting uses LESS battery, the 4G or the WiFi?
I am having another BIG frustration, trying to talk sense into my mother, who just got her first smartphone, the S4. She cannot remember the easiest tips and I show her over and over how to set the brightness, how to turn data on and off (she has no other internet, so she NEEDS this to keep up on FB and sell her trinkets online, but because she can't immediately gain the knowledge of how to set everything exactly how she wants, she's telling me she wants to switch BACK to her ancient DINOSAUR of a POS keyboard phone with NO DATA use on it, JUST calling and texting! She was literally paying $50 a month MORE for her POS 10-year-old phone that is literally going to crap out at any minute, and if she switches back, she can't use the Edge Plan from Verizon, so she will still be paying MORE to use a crap paperweight junk phone and have NO internet! She is driving me CRAZY!! Anyone know ANY way I can convince her to keep the S4???
Thanks!
Regarding the first part of your post. It would be useful if you let us know which device you got and which version of Android it is running.
I'm on the latest lollipop and i don't experience your problems.
Regarding battery life i do get full day with heavy usage and 2 full days with light use.
How many hours of screen in do you get?
For your mother. Just set the device once she will not change it. Clean the launcher and just keep the apps she use.

Super Unstable

Hey guys, i need some help. Recently I Odin the latest Tar OG1, and used the debloated OG1 stock Rom that is in the Developer Forums. Everything was going well and after a few weeks I started noticing that my phone would start to lag really bad and then just freeze for long periods. I can't do anything while it's frozen and more than often it will restart on it's own. I've wiped everything and restored it using the Tar and even on complete stock it does this. I'm starting to think it has something to do with my actual phone but I don't know how to make sure. I had twrp and even that lags and freezes sometimes. I don't know what I could have done to make this happen, I had xposed installed, and i was running the beastmode kernal as well. Anyone have thoughts on this?
Update: so now my phone just cut and restarted again out fo the blue (I was trying to set an alarm) and my screen went black with fading lines on it, then suddenly it started vibrating nonstop., had to yank the battery. turned it back on and now it just restarts when idle.
One of my Note 4's started lagging real bad, locking up (requiring battery pull), and constantly restarting. Its completely stock, I've read around online that its likely an issue with the onboard eMMC memory on the motherboard dying. Only cure is to replace the motherboard.
I found a work around though, download an app called Wake Lock (or something like that), start it and set to partial wake lock. Phone basically runs like nothing is wrong with it now. Have about 6 months before I can upgrade so hopefully it holds out until then.

Dude you are awesome!!! I managed to odin the stock tar again, went through setup at super slow speed just to be sure, and then installed the app. As long as i take some caution it is running like normal again! With the Note 7 recalls this really help buy the time I need before i can get one. Thank you so much!

No worries, I did lots of reading online and banging my head against the wall when it started acting up. It was really weird, it was acting fine one day, then the next slow, lagging, locking up, and restarting. I tried factory resets, reinstalling old stock ROMs, taking the sd card out. Finally stumbled onto a post in another forum where a guy mentioned that app. Since installing it, as long as I keep it running, phone acts like normal, that's about a month now.

Im not gonna lie, i don't know exactly what it does. Does it drain your battery quick by chance? Mine dripped from 79% to about 40% in the span of an hour. Not sure if its because of the fresh flash or not
The Note which has issues is my wife's phone and she is a "power" user, lots of screen on time (think her timeout is set to like 2 minutes or something like that). I dont think she has seen any appreciable difference in battery life, but I'm sure it does drain a little bit as the partial wake lock never really allows the phone to enter into a true sleep/battery saving mode.
I had freezes and boot loops, and it turned out to be a bad battery. Strange, right? But it's true. I replaced the battery with a new one and everything worked fine again.
The battery had just started to swell, which is a sign of a failing battery. So, even if the battery isn't your problem, it's always good to check it now and then for changes in thickness.

Official random rebooting fix

I've read 10 pages on this subforum, random talks about updates, LTE fixes, etc...I've yet to find a single thread giving an official fix for random rebooting? I get this at least 4x a day...regardless of charging or not, SD card installed or not, all the latest updates are installed. I can't be the only one and if so, why isn't this a Sticky issue at the beginning?
I and few have others have the unpleasant experience with rebooting. But it was a little relief that this issue is not just with my Note4.
Laughter is the key to happiness
I had this problem with the early 6.01 stock roms, but it eventually calmed down. Now I get a reboot about once a week. I just assumed the first couple 6.01 stock roms were buggy.
I suppose lots of hardware issues could also cause it.
I bought this phone used for $140, I don't know how long it's been running 6.01, but I'm guessing he knew it had this issue. It happens 3-4 a day for the past two weeks. It'll do it while at rest on or off a charger, middle of use, etc. Aren't they're apps that can log what's going on when it fails so this can be resolved, like acatlog? These phones aren't new anymore, it seems there should be a fix out by now...root and overclock while undervolt, remove bloatware from Sprint Normal Apps or whatever it's called, etc

So, what rom is the phone running?
Bone stock at the moment. I'm going to let a Sprint store give it a looking over, but I'm not hopeful as they're usually useless vs what I can find here myself. At minimum I'm going to root it and remove bloatware, but I haven't reviewed roms yet. Unless this thing stored it in memory, but I was doing a copy and paste last time it froze and rebooted, yet I was still able to paste when it came back on...safe to assume that means it's only a soft reboot?

What version of stock? If it's old, some of the early 6.01 roms were pretty buggy. The current stock rom is QC1, which just began to roll out this week. Make sure you are on the most current rom.
Last update I received was this week which turned out to only be a security patch.
So, you're on most recent rom. Only suggestion I have is full reset. If that doesn't do it you've got a hardware problem.
So I hope I don't jinx myself, but I think a new battery has solved my issue...with some extra steps Let me explain.
Bought the phone used, it'd reset about 3-4x a day...being charged, being used, whatever. It'd reboot anywhere from 80% down to 40%, no rhyme or reason. Sometimes it simply wouldn't allow me to turn it back on, the light would flash blue while dimming in and out, but wouldn't power up the screen. Plugging it back in and it'd be at 30%-45% no matter what. I downloaded an app called Battery Calibration from Meza (sp?) that had a little Android logo with a % on his chest. Resetting may or may not have completely solved the problem had it not soft reset when trying to get battery stats to refresh themselves. It's my understanding that if it reset, it rewrote a battery stat upon reboot, making this step useless.
I got two new batteries from eBay (http://www.ebay.com/itm/112344168032?_trksid=p2057872.m2749.l2649&ssPageName=STRK:MEBIDX:IT), I charged one in the phone and one on an external charger. Even after running with the new battery, it still reboot once and shutoff around 43% reported on the phone itself. Once plugged in and phone still off, it said it was at 15%. I swapped in the other new and charged battery, powered on the phone, plugged it in until it read 100%. I fired up the Battery Calibration app, unplugged the phone as directed and then to force the battery to drain faster, I let YouTube play uninterrupted for about 4hrs. NOT A SINGLE REBOOT!! For the first time with this phone, it actually stayed on and dipped below the 30%'s and gave me a warning when the battery was getting low (yellow icon) and getting critically low (red icon) before it finally powered itself off at 1%. The phone is now charged on the factory fast charger, this time playing Pandora with the screen off and uninterrupted as well...it's currently sitting at around 57% last I checked.
Once it's fully charged, I'll run it like any normal user (texting, music, etc) without being plugged in and if all works well, it won't reboot.
Hopefully this helps someone with the same issue and is a $8 fix since I bought two batteries.

I reset the phone the day I got it.
if your phone often reboot many times in a day, make sure that you don't use Ram kernel V6 or v7 for your Rom, V5 is only version that not make your phone randomly reboot. I try Ram kernel v6 and v7 in Note 7 port rom, note 5 port rom and stock either, and this kernel version always make my phone reboot many many times, unless i flashed v5 or stock kernel, the problem had gone.
I had this problem. I replaced the battery with an official Samsung battery I ordered from Sprint, and the problem went away. Simple as that. No reboots ever since.
Purchased a new battery from Amazon, Samsung OEM, problem solved. Put back old battery guess what it started again but only when battery reached 70% of the original charge. So it must be the battery memory problem.

Four batteries later and this still happens. Can this be addressed via rooting and then undervolting? I remember phones of the past where people would overclock for speed and undervolt for battery life, but one way too high or too low and you'd either get random rebooting or freezing. This is so god damn annoying!!!!!!
