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?
My s7 is arriving today and I was all set to root. But I keep reading posts about how the phone becomes super laggy with all types of battery drain.
I guess I'm trying to gauge if that's a real issue or people just overreacting.
If anyone can share their findings and thoughts I'd appreciate it.

If you follow all the steps after rooting it's not bad. Sot is not as good but standby time is the same for me. I also have no lag.

Follow swicks lag thread. When I first got my s7, I couldn't go more than 7 hours without having to charge it. First day with the tweaks in his thread. I got this
Look into the U firmware. It removes the Verizon bloat, stable, and great battery life!
You can fix idle time on stock by downloading ez disabler (Samsung) from the market and getting a XML list of everything to disable.

I rooted my SM-G930V, and I am experiencing some heat from the phone when it is sleeping- not so much when it is unlocked and operating.
As for battery drain- I have not noticed any major loss in battery usage.
There also seems to be a significant speed issue with speed- took around 5 seconds to open the settings app, But this can be fixed by
editing CPU governor from interactive to ondemand with Kernel Aduitor.
I am looking into this article to fix the heat issue: http://forum.xda-developers.com/ver...guide-to-fix-s7-lag-root-s7-variants-t3441715
Stang5litre rom and you wont regret it
You can do a lot with various Xposed modules and other root apps to mitigate the drain, but there is some drain nonetheless. SOT takes a bit of a hit. Standby time, it's negligible.
I recommened personally sticking to stock. I use to be rooted and between battery life and issues I went back to stock. This was before the roms came out. I have a new born and a family I can't play around with signal dropping, phone restarting, lagging and whatever else. I like stock with nougat beta. If the bootloader ever gets unlocked or something else that interests me to root maybe one day but not worth it for me right now.

With Stang5litre's rom I've have zero problems.
There is no way with any rom or any app (unless it is magical and brand new) that you aren't having issues with this phone and root. I tried every app I could and 2 roms available here for it as well and it was still laggy with terrible battery life. I held on with this phone as long as I could hoping for a better root method but I couldn't wait any more. The performance after a few apps and kernel changes is still terrible compared to stock. The battery life after fixes and kernel changes is equally as terrible. I was getting around 1 hour and 10 mins of SOT before it was completely dead. I loved the phone and stock it had great performance and battery life, but that eng kernel for root just destroys it. I NEED root on my phone or I would have kept it stock. Word of advise, keep this phone stock or sell it and get something that can be rooted and actually stay usable.

I get about 5-6 hours SOT and no performance issues. I occasionally overheat but that's it. Different people have different results, for whatever reason.
Hi guys,
I have purchased Note 4 recently and it seems to be heating in minimal tasks also like surfing the internet. i have flashed KITKAT, LOLLIPOP(default) and MARSHMALLOW but in all these firmwares the problem seemed to be consistent. Earlier i used snapdragon phone which was clocked at 2.3 GHZ and used to heat @ heavy games like No Limits, with recording on but this one is heating in angry birds itself. Though no lags are observed. I have not tried the Marshmallow version latest yet but some body told that latest update fixed heating issue. The root problem i see is its Processor clocked @ 2.7 GHZ, i mean this much we see in PC. I dont understand why they have gone so far. Now Samsung kernel must be clocked such way that on demand it bumps the frequency to max. This max i want to limit to 2 GHZ but without knocking down KNOX warranty. If some one has latest updated Marshmallow release and can confirm that it is indeed not heating please comment or tell me the solution to this problem, i really like this phone but hate when it heats. I am ok with slight lagging due to underclocking. i am willing to flash kernels with lower max frequency via ODIN. No custom recovery intended. Also i dont want to loose on warranty.
Thanks and Regards,
Really looking forward to solution

I have a Verizon Note 4. I did have heat issues with Lollipop. Since I installed Marshmallow and did a factory reset, it only gets warm with heavy use. Some app updates have had my Note 4 running warm, but a reset of the phone seems to fix it.

Seems like custom rom is the only option bro
The Snapdragon 805 SOC does have a bad habit of getting really hot when running heavy tasks.
Not only was my phone Hot for every second I used it but... Look at this amazing SOT.
I finally figured out how to keep Google play services from draining the battery: burn through your entire battery before it even has time to start up.
My phone is not even one week old and it lags like crazy. Especially when I put it down for few minutes and pick it up to open a notification. Even scrolling up and down stutters like crazy for a new phone.
I noticed my CPU is always above 30%. I have ZERO open apps in the background and this is the lowest the CPU gets. That doesn't seem normal to me.
I'm using System System Monitor app to measure. Can someone please install and confirm what you are seeing on your S7 Edge please? I am in the snapdragon variant.
https://play.google.com/store/apps/details?id=com.dp.sysmonitor.app
Also, shouldn't I be seeing 8 CPU cores instead of just 4? What am I missing? This is an Octa Core phone, I'm only seeing 4 CPUs
Please advise on what is showing on your phone. Appreciate it.
What version of S7? Snapdragon (US versions) has quad core. Exynos (International) is octacore.

Erase your cache memory in both Settings->Storage and via the recovery menu (hold the volume up, home and power keys at the same time from a powered off phone).
If those don't help, might need to try a factory reset and start over.

I have done factory rest twice last night and even with fresh factory reset, CPU usage will NOT go below 30%.
Can someone please download the below app, clear all on recent apps and tell me what does your CPU usage read?
I have the snapdragon version.

Just downloaded it. Also Snapdragon, Blue CORAL. Been watching it for 2-3 minutes, and it's around 30% at rest, all apps closed. Saw 29% once, but mostly 30-33%. I have all the latest updates, Verizon. I have no noticeable lag, at least compared to my Nexus 6P, and battery life is just awesome.
make sure u dont have power saving enabled

Funny me and you have the same exact setup even a Nexus 6p. I find it very strange that CPU at rest stays around 30%. CPU Usage on my 6p at rest is around 2%. I really thought my phone is defective.
I'm interested to see what other s7 edge folks report for CPU Usage at rest.
Just started the 6P back up and installed the app. Yep, much lower, once it stabilized. About 10% average. But the battery life is so good on my S7E, that I don't think there is a direct cause-effect here, since our stats are close to the same. There is a warning in the description of the app saying it doesn't run well in all MM devices.

I am convinced now that this monitor app is not really reflecting correct CPU usage on S7 Edge.
you guys s7 edge uses performance govs and uses hotplug to control cores. That is why your cpu usage is sky rocketed currently. Root change gov and than it will not happen.

Thanks, but I'm not rooting this phone. First time I've not rooted an Android, and I've owned Android's for a lot of years. Rooting can bring it's own set of issues, like making upgrading more difficult. And the CPU usage, if the above app is correct, is not impacting my battery life at all. I unplugged it last night when it hit 100% charged and it was down to 98% 7 hours later. I can live with that.

I don't belive that CPU app is playing nice with s7e monitoring. I'm not concerned anymore. Think this phone is alright.
I jumped in and bought a K1 to replace my dying GPad GPE. After 3 days, this seems like a huge mistake.
The K1 is very laggy in basic apps like Play Store and Chrome, does not register touches very well and has terrible battery life. I even charged it overnight and didn't get a full charge. On top of that, I am constantly getting the screen overlay message any time I need to enable a permission.
What could be causing this? This tablet is so highly regarded I don't get it.

For charging you need a 2 or 2,5 A charger. Then it will charge (if it's not faulty) in around 2 hours. The screen overlay message is coming from the quick launcher (or how it is called). So disable it or give it the right to draw over other apps.
I don't have problems with lags or touches. Are you on the latest updates?

I am using the correct rated charger. This even happened when charging with the tablet off.
I am on the latest update. I waited to install my apps until after all updates were applied. The touch issues may be lag related. The back button almost always requires multiple touches. Keyboards often time register multiple touches or just freezes.
I am also noticing network issues. Apps report loss of connection when the wifi shows connected.
I hate to say it, but I am leaning towards returning this for a Samsung.

Also a recent owner of the k1. Running stock firmware (1.5) but with BitO-K kernel. The only thing I am experiencing is mediocre battery life, charges from 50-100% in under an hour using a 2.5A charger. The only thing that sucks, and this goes for android tablets in general, is the removal from 4.4 of the TabletUI. Seeing we're already at 7.1 and TabletUI is still dead, it looks like we'll have to fight to get it back again.

That lag is not normal. And my tablet charges from around 10% to full in about 2 hours. Maybe you should try a factory reset. If that doesn't help I would return it.
I won't buy a Samsung tablet. I would try a replacement. I own the k1 for a year now and I'm still very satisfied with. And Nvidia updates it. Which Samsung usually doesn't.
Don't listen to Nvidia trolls... ⬆
Your experience does not sound typical. Perhaps it's a hardware issue, but I agree with @edisso10018 that the first step would be a factory reset.
Wish you luck!
The Nvidia CPU is pretty good shame it's not the X1, It performs better then some of my phones with QC chips, Do a factory reset and see if the lag is still there, Battery life is poor can agree on that
My k1 is over a year old it is still playing games with no trouble yes a agree with the battery life but mine charges with no problems a have noticed a little slow down but am not running bit os updated kernel yet but a still rate 10/10 best tablet a ever owned.
Tablet is laggy, no denying it.

K1 here-- I don't run stock (DU 6.0.1), but I used BitOK for a while and realized its not very good. Switched back to stock kernel (from my ROM) and its more stable. You don't lose out on much anyway-- BitOK doesn't have features I want like voltage control. Examples of instability caued by BitOK: GPU was stuck at ~350mhz, would not ramp down fully to 72mhz. Also stock is smoother. You can still use adiutor to monitor and control a few things.
One more thing: be very careful when flashing blobs and other stuff in fastboot that it is for the K1 version and not OG shield! A lot of devs posting these things arent explicit as to which version. DTBs and Blobs are specific to the shield type-- one might work for the wrong tablet version, or it might brick it, or it might be unstable.
As for the Batery life I can tell you it does suck even on the best case scenario. There is no way around this as it is small and the large screen, as nice as it is, sucks a lot of juice. Lowering brightness helps somewhat but still I'll be lucky to get a couple hours of SOT out of it.
For the price its a great tablet, with a few small compromises, such as bat life, but thats the price you pay for great screen and sound at a cheap price. We are lucky to have at least a few devs still doing work with this device, and luckier still that nvidia is STILL supporting it with updates, even if slowly. They recently announced 7.1.1 will be forthcoming.
Mine was laggy too, I flashed stock firmware with my PC and now it's working perfectly.
Bought mine as a refurb and it works fine. I think you either have bad hardware, or a bad install. Try flashing stock and see if it improves.
Tbh my only complaint is with battery life, I switched to BitO to see if it got any better, the tablet is smoother with this kernel than stock but the battery is the same, I wish we had UV'ing, my favorite setting on any kernel, back on my N10 my battery could easily be improved 10-15% and the heat was reduced drastically, good binned ones could shave up to 200mV on some steps. K wish this was implemented

I just bought a K1 (discount price 169€) and I don't have this problem at all. Even if I use only 1 core (settings performance) for basic app it's smooth smooth smooth.
And the battery life is huge !!
For gaming tho I switch back ofc the performance setting.
:good:
I bought a K1 three weeks ago to use as a display for my phantom 4 quadcopter. I am very impressed with its performance. I'm not experiencing any lag other than at startup. Once it's up and startup is finalized I dont have any problems. The battery life isn't great, I'll agree there but hopefully it gets better with Nougat.

I bought a K1 last week to replace my aging Nexus 7, did a factory reset and still wasn't satisfied with it being laggy. Did my share of Google searching and finally stumbled upon a quick fix to try : disable Daydream. Since changing this one setting it has been very smooth since, no issue for lag or touch registrations.
Give it a try, might not help your charging but I did notice a much reduced battery drain while sleeping also.
My only other changes were to root, change the DPI to 240 and use the Google Now Launcher which compliments the display nicely.
I wasn't happy with it as well until I flashed cyanogenmod 13 and a custom kernel with overclock. Now it's a beast, battery is great, signal as well. And I also now have the option to OC the processor to 2.5 GHz before I play some more demanding games and then set it back to 2.2 or even lower if I won't need all the juice. Seriously, the stock marshmallow ROM sucks, I have only heard bad stuff about it. Also, the nougat update is about to come out so I'd give android N a chance, too.
About the battery life -- see which apps are using the most juice under settings/battery/. Some of them may be using more CPU cores, and have a higher frame rate than is needed. Go to settings/App optimisation/ and crank the numbers down. Next go to settings/Accounts and see the long list of things that want to autosync with you. Turn the autosync off for those you aren't using. Turning off wifi except when I am using it has made a significant difference for me as well.

Putting the CPU at 80 or 90% CPU speed in the performance settings will get you that reduced power consumption. You might not even notice the speed difference. These speed tiers also run at lower voltage.
Using the GPU frame rate limiter will dramatically extend gaming time too. I find 30 fps acceptable most of the time.
Of course it would be nice to run the thing unrestricted, but it's just not practical when you also want battery life. Look at what Nintendo is doing with the clock speeds of the X1 in the Switch.
