I need help with my g2. my battery life on this phone is very inconsistent, sometimes i can go 50+ hours on it with 6 hours screen time, but lately my battery has been draining for no reason at all. Im not even using the phone and its rapidly draining for no reason. This all started happening when the gps kept on turning on i read about the carrier iq service and the google location to turn them off. But it doesn't really help much. On my battery manager it says that the android system is first with like 85% or more and it says that my gps has been on for hours and hours even though it hasn't. I don't know what to do i can barely make it through a day now. Should i root my phone? I like the lg ui and i want to keep all of the features such as q slide and especially knock on and off. Can someone help me out if you have had the same experiences. I want to turn off the iq agent permanently. Is this possbile? I have never rooted a device before so im a complete beginner.

Download better battery stats and see what wakelocks are causing the drain. Are you using Google+? Are you on Wi-Fi all day? Have you tried uninstalling all your apps and adding them back one at a time until you find the culprit? Something is keeping your phone running...

Yes i have downloaded better battery stats, and im not using google plus. And im not on wifi all day. The battery is just draining for no reason i even end alot of the running apps such as google location service, facebook, carrier iq agent. I was wondering if i could root my phone and delete carrier iq and get those apps that can help with the battery life, yet keep the original lg ui with all the features.

Has anyone been experiencing bad battery life on the g2? When i first got it a month ago it was amazing easily getting 50+ hours with about 6 hours screen time. But over time its been getting worse. I already did the whole stopping the carrier iq and all that, it still doesnt help much. Now when i go to sleep and wake up 7-8 hours later my battery drains 50% or something like that for no reason, no wifi or anything on or synced. I did see some posts about people experiencing bad battery, this phone is supposed to have amazing battery life whats going on? I rooted my phone, still on stock rom, wondering if anyone has fixed their battery issue. Would installing a new rom like aeon v3 help improve battery like its supposed to be? Its getting frustrating, my gs4 had worse battery but at least the standby times werent as bad as they are on my g2. Any fixes for this?
There has to be something running in the back ground draining battery. If not try finding a battery Conditioning Application

Based on the above it could be a few things.
If you want to check a few things on the phone side you can:
- install GSAM Battery and let it keep an eye on what's actually using your juice. Then either remove, modify, adjust settings, etc, for whatever is using it. If it's an app... delete it. Reinstall it.
- You can try a factory reset
If neither fix it then you can try another ROM, but if your battery is just as bad with a factory reset I'd lean towards the battery. Maybe you have some bad cells.
I've had mine for a bit, and I only lose a little bit if not touched overnight.
My current setup:
- Madhi 4.4 KK ROM (1/18 build)
- Obviously rooted with the above
- Greenify on all my non-necessary apps (hangouts, weather and one other app spared from this)
- All my apps auto-sync features are disabled since I just run it once in a while, and things like mail / etc I don't need push anyways
I get pretty solid life even after a few moths of use now.

first, install betterbatterystats and look for wakelocks, try reseting the device. batterylife also depends on how you use the phone...i can get 9hrs on screen time reading books with still 15% left or drain it in 3-4hrs playing games.

Yes i have downloaded and used gsam battery app. I dont see anything unusual in my stats, also using better battery stats, its been in deep sleep for most of the time, and it doesnt say the phone was on or running when the screen was off. But for some reason i wake up and my battery is decreased by 50% again....I am using greenify and hibernating alot of those annoying apps. I am stopping apps that are running . And on the phones battery manager android system is first with 34% but it says its only been running 11min, and no gps is listed. And my screen on time was 2 hours those are what i foudn when i woke up with 20% left, at night it was 70%. I seriously think my phone is messed up when im using it its not that bad, but for some reason when i go to sleep and leave it alone it dies for no reason....

Ah i am using better battery stats, and nothing seems to be out of the ordinary, its been in deep asleep for most of the time. And the phone doesn't say to be on when it wasnt supposed to. Same thing on the phone battery manager it says android system is 34% with 11min being on,and screen is 2 hours. When i woke up my battery went form 70 to 20%.....i am using greenify, and stopping running processes, like carrier iq an other apps. i dont know whats wrong...this is getting frustrating, i have also factory my phone already, it was fine for a few days but now its constantly draining like crazy at night...i love this phone, but i think mine might be messed up! You think changing the rom would make it go back to normal? Even though my phone isnt supposed to be behaving like this with stock...

I definetly would try it. Also you could try different kernel. But its beginning to sound like there could be a defect in your battery. If nothing helps i would send the phone to LG and let the battery replace. You are still in warranty, right?

my battery has a problem too..
when my phone is idle sometimes the battery level increases by 1 or 2.
when im playing heavy games like gangstar 4 the battery decreases every 2 mins and the temperature reaches 40°C. and when im just browsing it decreases every 3-5 mins with a temperature of 34-36°C. and when im watching kuroko no basket (wifi off) every episode just consume 2-3% of the battery (24 mins. = 2-3%)
and the temperature is about 28-30°C.
I think my battery drain problem depends on the temperature
by life span i mean battery life.
when i am off work i leave my phone on the side and basically do nothing with it maybe make 1 call or send a txt the phone over a 9 hour period uses 12% battery i have monitored this over 6 days.
however when i go to work and sling my phone in my bag and leave it there all day it uses over 70% battery so i am curious why and how and if there is a way to reach a happy medium.
my phone is not rooted.
i find i am constantly turning off "watchon" and other naff samsung apps which i do not use.if i look in the settings/battery options "android os" is the biggest battery drain.
my phone is uk on o2 network baseband is N9005XXUDMJ7
is there a save way to root the note 3 and is there a list of stock apps that i can safely uninstall.
sorry for lame questions have not messed with android phones for a few years now.
cheers
If you have very weak, marginal signal, phone will constantly search and try to reconnect and that will kill the battery rather fast. If I had to speculate, somehow putting your phone inside the bag cuts the signal down and makes the phone work overtime trying to stay connected, either by location of the bag or the lining? But loosing 12 % over 8hrs is not stellar either, just for comparison my phone is on for 10hrs since last charge , I made 5 short phone calls, checked the weather and news on the web quickly and I'm at 95%, but I do have full bars in my office.
many thanks for taking the time to reply, my phone is stored in my work bag which is kept in the cab of a bus (i am a bus driver) i would tend to agree that the signal bars are very weak when i do take it out of my bag, maybe i sould it try it in my shirt pocket for a day and see what happens.
Even tho 70% drain is too high compared to 12%. I will still point out what earlier poster did. Signal is very important for battery life. If you have good signal, your battery life will be relatively better. Though you said that you are not rooted, you should go to my Battery Saving tips thread and look around for a few pointers to help with your battery troubles.

once again thanks for the reply, i followed alot of your battery saving tips and performance has improved greatly. i also think i was a victim of the android os bug i done the most basic of things and put the phone in airplane mode turned it off removed battery for about 5 minutes and then put battery back and turned on. android os is now way down the list of app draining processes ( it was at 68%) its now at like 6% so at the minute i am happy, mind you i am off work and my phone is not stuck in a bag lol
next to read your rooting guide.

I've had an AT&T Note 3 since January. The phone is great but since the update to 4.4.2 I have been experience horrendous battery life, to the point that I'm having to charge it throughout the day.
I work construction and use my phone for several hours per day, resulting in 2-3 hours of voice calls and 2-3 hours of screen time. My last Note 2 and the current Note 3 used to be able to handle my workload while being unplugged from 7AM to 10PM at night.
If I was to root my phone, could I gain back my battery life? I have never had the need for my phone to be anything other than stock but I am desperate at this point.
Thanks
Rooting your phone will not result in having better battery life. What you can do is detect apps that keep your phone awake. Another method is to flash a custom kernel with lower voltage or one on which you can undervolt yourself. Be aware that by rooting and/or flashing custom recoverys/kernels or firmwares you'll trigger the Knox counter. This will void your warranty. There is no way to revert it.
Please use the Q&A section next time you have a question. Hope I could help you a little.

I appreciate the reply. I was hoping that rooting would allow the phone to run off of custom firmware and not have the horrible battery drain many Note 3 users are experiencing after the 4.4.2 update.
I have installed GSam Battery Monitor for over a month and been monitoring it daily. I'm consistently seeing Android System and Kernel (Android OS) using 40% of my daily battery life and Media using another 15%-25%. Other than that I've been unable to determine much else. I do not play games or Facebook, I just talk and text all day.
Is the warranty on the phone one year? If so, I'm 2/3 through it and would be willing to void it for better battery life.
I have looked through all I could find before posting, but honestly am somewhat overwhelmed by all the information on XDA. This is magnified by the fact that there are many versions of the Note 3 and different carriers.
I have a N900A Note 3 and am looking to get my all day battery life back and appreciate the help.

Don't worry, it's normal to suffer infoglut the first time looking through xda. You'll get used to it =)
So you have the AT&T version of the Note III aka hlteatt or SM-N900A. You're device has a Qualcomm chip built in like most of the Note III variants out there. There's also a Note III variant which has an Exynos chip built in but I think you won't confuse Exynos firmwares with those dedicated for Qualcomm variants. The ROM threads ususally have pretty good descriptions about that. AFAIK most custom ROMs are compatible with any Qualcomm variant. E.G. any AOSP/CM ROM for the Qualcomm Note III has a unified build carried by the name "hlte". Meaning, that as long as you don't flash an image meant for the Exynos variant, you should be good.
40% for Android-System and Kernel isn't normal at all. I also use GSam Battery Monitor. Android-System and Kernel only use about 19% of the battery on my phone. Something that helped me when I had the exact same issue was to switch locating method from high accuracy to power saving. You can find this setting by long-pressing the GPS icon in the notification drawer. The location settings menue will pop up. Under "Mode" you can change to "Power saving". I'd be happy if you could report if it did work for you.
You're welcome =) Just hit the thanks button.
If I may add my own comments here:
1. you should go to note 3 ATT forum and there find proper method to root your phone, we have towelroot program that can root phone very easily without breaking knox warranty, albeit I don't know if it works on your version, it worked perfectly on mine (t-mo)
2. While it is true that root by itself won't do anything about your battery usage, many programs that really help need root
For example greenify, titanium backup or android assistant require root to disable many useless (useless for you that is) programs that drain your battery
3. I totally disagree with Nitrous that GPS is the culprit for high battery usage. It is my experience that GPS all by itself does not work at all unless the location info is requested by some other programs. Google maps for example only run GPS when screen is on, when screen is off, GPS is off also. However some badly behaving programs can keep requesting location even in the middle of night, but IMO those programs are the problem, not GPS itself. I have GPS, BT and WiFi on 24/7 and with light use my phone could last 4-5 days. If GPS was draining battery as many people think, phone would never last that long.
What you should do is go to ATT forum and find towelroot method, root your phone and freeze, or disable apps you don't use. For example I don't use Bloomberg, Yahoo, Facebook, Hangouts, indexing etc (your list may be different, since different provider) so I have them frozen (won't start up) . If I ever change my mind, I can unfreeze them later.
You can also run programs to tell you which apps use most battery, or wake the phone from sleep and then decide if you need them or not.
BTW sometimes full reset and cache clear can fix some of the problems, so maybe that should be the first step.
Once you find which program /s cause problems your phone should last whole day. I could easily get 6 or more screen hours on my Note3, unless playing some intensive games, so should you and it just took couple hours to identify and disable all the bloat and there is a lot.
I also experienced increase in battery usage after updating to KK, but I have not found a time to look over the bloat and redo my program freezing efforts yet.
I know that GPS doesn't drain battery that much. But trust me, it is very likely to cause that type of behavior. I'm in this forums since a couple of years. In most cases, when Android-system and Kernel drain unusual amounts of battery it was location services that was causing it. But not because they were using GPS, but because they kept the device awake the whole time. And there you see my point of switching locating methods. In 90% of the scenarios where people described this kind of behavior of their devices, this solved the problem. But you're right in saying that it's not a permanent solution. I agree to your first two points.

I always have GPS off and only turn it on when I need it though Android still has the higher or second highest battery usage.
I agree, root and uninstall /freeze bloatware. You'll be surprised.

Just to give quick update, after I wrote my comments here, I fully charged my phone and went to sleep. In the morning battery was down to 80% and that finally prompted me to action. I freezed some apps, cleared cache and did some "housekeeping". I don't know what did the trick, but this time overnight my phone went from 100 to 98%, 10 times better than a night before. Now, after 18 hours of some light use like few calls, couple games, light internet use etc it is still at 80%, so it's pretty much back to what I had before update. I wish I wrote down what I did to track particular culprit in my case, but it is amazing how couple bad apps can ruin battery life, but at the same time killing them turns things around so much. All in all, out of some 340 apps and services on my phone, only 21 are frozen and about 30 are stopped from starting at boot up, but are able to start later if needed.

Last question; 340 apps system-wide, or 340 PlayStore apps?
I have had my phone for several years and developed a good sense of the battery's life (meaning what the remaining battery percentage would be after a period of time). For instance, if the phone were fully charged when I went to bed, it would typically read 94% when I awoke.
Starting a few months ago, the battery began running down quite a bit faster than it had previously. The first thing I did was install Greenify, but that made essentially no difference (my phone is rooted, stock ROM, and I had already removed all bloatware, turned off autostarts, etc.)
Next, given the age of my phone, I suspected that the battery itself was wearing out, so I purchased a new one (a RAVPower 3220mAh Replacement Battery for Samsung Note 4 from Amazon - a battery with good reviews). However, the battery performance did not change.
Based on various recent reports about Bitcoin mining malware running on phones, today, I ran adb->shell ps -x and examined the output. The process system_server was reported as being responsible for 79% of the combined user and system times. The five processes /system/bin/surfaceflinger, /system/bin/mediaserver, com.android.systemui, /system/bin/mpdecision, and com.google.android.gms.persistent were reported as being responsible for an additional 11% of the combined user and system times; with 215 other processes being responsible for the final 10% of the combined user and system time. This makes me believe that there is no malware running that is hammering the battery.
What else could be responsible for the recent degradation of battery life? Could some device in the phone be degrading and drawing more current than it had previously? Note that I have not installed any system updates nor installed new apps recently.
Strange.... Quite awhile similar happened to me. But my thoughts was on the rooting side. Few years ago I had Note 1 and try a bunch of custom ROMs Battery life wasn't so good but I thought it was because of mostly bad battery optimization in many of custom ROMs. When I bought Note 4 I tell myself that rooting and custom ROMs are the past. But recently (God knows why) I rooted my Note 4. Since I had no time to install and play with custom ROM I left it just rooted for a few days with a stock ROM. Immediately after rooting, battery life was rapidly start to drop. I'm turning on my phone at 7 AM and about at 3 PM battery was dead. Since then battery lasts almost a whole day - at least until 7 PM. After rooting I didn't install any new app. I even didn't stop or uninstall any of apps or processes. Just did a root and nothing else. Immediately I install new stock ROM and unrooted my device. Battery life is now somewhere in the middle - dying at about 5 PM Yes, I know what is rooting and it shouldn't have anything with battery life. But at the other hand my case said that it does. Also I'm thinking - why most of manufacturers try so hard to stop users from rooting? Yes, that power shouldn't be added to any mobile phone user, but putting such effort to stop even power users of using advantages of rooted devices? Please! So much time and money spent just to "protect" users of doing some mess? There is no logic at all. So that is why I thought that Samsung (other manufacturers too) doing something "under the hood" with their devices... Yes many of "power users" will tel that I am wrong, but isn't it Samsung recently admit that they are listened (I'll be nice and won't say "spy") users of their smart TVs who had voice controls?
These days I've been looking for a new battery, but while I'm looking at your case, it seems that new battery wouldn't help me... or maybe it will? I'll give it a try.
