I have noticed accidentally yesterday that after I had my stock headphones pluggeed in the Note, the typical curve of the battery drain became much flatter and the different wakes during screen off have almost disappeared. The moment I unplugged the headphones, the battery drain went back to the usual 2-3% per hour on standby.
I am running stock LQ3 and stock kernel. I am rooted, as I have flashed it through Mobile ODIN, over stock, rooted LPY.
I have quite a lot sync-accounts - twitter, facebook, gmail, email, weather widget etc. so I am quite used to relatively short battery life but the trick with the headphones came as quite a surprise.
Before writing this post I decided to test it today as well and it is the same.
So, could someone test this and report? I think that if this proves to be true and common, the devs could easily track what's happening exactly and sort things out, so that battery can live longer without the headphones plugged in.

Maybe before writing this post you should also have asked yourself, Did I develop something here or am I asking a question?

Ugh...I am terribly sorry, this was meant for the General Discussion. Please, admin, move it there.
I've noticed that same if the SAR of the last samsung mobile is very low, the reception is quite good compared to other phones.
Do you notice also an improvement of the signal reception? Because if it is the case, it is that your headphones are used as a secondary antenna, giving the phone a stronger reception and less power consumption (better signal = less need of power usage for processing the signal)
This is just a theory...
After some ICS ROMs I went back to Gingerbread, mainly due to poor battery life.
When Litening ROM 2.0 was published I flashed that one. I liked the GB version a lot. The battery life was remarkable, a lot better than previous ICS ROMs. Because Litening is not much supported I tried Alba, also LQ3. A surprise because battery life was the same. I think I'll stick to ICS this time.

Alba often uses LB2 modem (from GB) in his ROMs - maybe it is the reason. I myself observed huge batterey drain on latest ICS ROMs while connected to Wi-Fi at my workplace. Fixed it by flashing ZCLP5 modem (from early "LP5 leak" ROM).

Hm, that is an interesting theory. I am not sure, however, that the headphones' cable really improves GSM radio reception. I think it is only for FM reception. Of course I have no knowledge behind that, just thinking.
I have frozen lots or apps in Titanuim Backup like:
- the whole range of SNS's
- Social Hub
- Wi-fi sharing manager
- the infamous wssyncmlnps
- software update service, etc
Also I have stopped a bunch of receivers, using Autorun Manager Pro, and disabled a lot of processes from Autostarts.
This should mean that I have opted out the most common battery drainers. I have tried to disable auto-sync for the time being, but that does not seem to be much of a drainer, so maybe the real problem comes somewhere from the modem.

Hey dimcus, i've been having this WiFi vs battery issues with some routers(including the one at home), weird enough it doesn't happen on some of them. I did read somewhere about flashing te Modem file, what leads me to a couple of questions ir you don't mind. Are you on ICS? Do i need to be root to flash the Modem file? If not, any risks involved? I'm on stock ICS LPY DBT.
Thanks in advance,

I flashed the ZCLP6 modem earlier today, guessing that it would be better than ZCLP5.
It is too early to judge but first impressions are that maybe there is a slight improvement in battery on 3G but not something worth it over the stock XXLPT that I used to have and generally battery drain on wifi seems as bad as it has been ever since I flashed ICS.
I have read that some people dared to wipe their Notes and after that most of the problems had disappeared but I don't want to risk getting some brick.
I will try several other popular modems and will report back.

Please let us know how you get on with them. Currently on LR1 modem and noticing a few strange wakelocks.
I have been with LR1 modem for about 40 hours now. What is better than the ones before is the much better behaviour on wi-fi. Other than that it is hard to tell any differences. So far 7 hours since unplugged, 1 h screen-on, half time wifi, half time 3g - battery is at 75%

then I heard to go with speedmod kernel, which I did.
no change..
Can you'se tell HOW TO change the modem?? I need to do something... mine just dont last worth a crap.. half day..
should I try a modem? and can you please say how to do just the modem??.
my baseband is N7000XXLPT

thank you!
Unfortunately after several different ICS Roms (From Stock LPY to Cleanote 2.20) with several different Kernels (Stock, SpeedMod, Goku and more) and few modems (XXLPT, ZCLP5) I had to go back to Ginger due to extremely poor battery life. With all roms /kernels/modems combination the behavior was very similar. The phone was going into deep sleep pretty easily when idle with very low battery drain. On the other hand when using the phone I was getting about 10% drain each 20 minutes (A little less with data wifi and all sync off). I was also getting overheating with temp most of the times over 40 deg C. This drain was almost the same even with system energy savings on. I could not understand the reason for this strange behavior considering that many other users are having great battery life on ICS with their devices. Anyone is experiencing this situation ? NB now with Ginger the battery life is ok.

Battery drain with cm10 paranoid android
I am facing a huge battery drain issue. Used the phone for downloading and playing games and general usage yesterday and battery only lasted 3.5 Hours. Need to continuously watch the battery as it drops about 10-20% on idle. Checked the wakelocks and mainly wifi related, the phone is going into deep sleep just fine. HELP PLEASE!!!
lol continuously watching means you're the wake lock.
btw phone only has 3-3.5 hour screen on time. When playing games its usually less.
All do some reading into analyzing battery life betterbatterystats and cpu spy

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.

Hey everyone. Without further a do, I am saying that my N4 battery suuuuucks really bad. Started on stock rom, flashed Chroma w/ latest franco kernel. Nope. Still lots of drain (slightly better overall, but nothibg major). Then flashed hells doctor kernel. Nope. Lots of drain when screen is on, but stable with screen off.
Honestly, I've seen people getting 6h on screen time. And everyone says that these kernels and rom can increase battery life by a margin, while mine stays the same.
Oh and there is a thing. Ive recently broke my stock charger and now using apple's ipad charger. Mine was 1.2 A and the one from apple is 1 A. Is this is an issue we are looking for?
Or its just a 2years old battery running out of its life cycles...?
Thank you!

Nexus 4 battere sucks really no matter what you plus your network coverage may impact vastly on performance. Anyway given the battery is 2 years old, I would say it's gone even if it says it's good but again it depends on your usage like continuous tethering or other heavy activity that makes the phone run hot

Well my usage can be heavy surfing on FB, Instagram and definetely FB messenger. I often use chrome and mainly everything is done under Wifi.
According to my screenshots, you cannclearly see that shes (battery) is ok when screen is off, no drain and etc. As soon I start using it it drains A LOT. Almost 90° angle on diagram It's crazy.
Plot twist: To prevent spam on the XDA forums, ALL new users prevented from posting outside links in their messages.
Yes, i have a new battery which was working well, but I flashed factory image 5.1.1 xxx47v and the batt life is really horrible now.
It's easy to replace the battery, I recommend taking out the sim card tray before taking the back off though.
I haven't been on here for a long time, whats the best rom, for batt life. I'm willing to go back to kit kat if I have to .
Also note that some of the screenshots with 6+ hours of SOT the user has handicapped their devices (disable 2 cores, lower max cpu/gpu frequency, etc).

Hello everyone!
So I have been having these battery issues since April security patch. the phone gets really warm to the touch even by doing the simplest of things like browsing and watching youtube. Android OS keeps the phone awake 80% of the time and I am only getting 2-3 hours of use throughout the day. Restored the phone to factory settings(fresh start, nothing restored) three days ago and still the same issue. Android OS drains the battery life even though I made sure that only google apps are installed on the phone.
But today things got even weirder. I disabled Google Now and location services as a test and the battery drain and heat issues were gone temporarily. I was getting a great battery performance from morning to afternoon. I check my battery stats and I notice that Google services mysteriously drained 17% of my battery life and that it's been running for 21 days straight? That's impossible since I just did a fresh reset to the phone three days ago. I rebooted the phone and that "Google services" drain changed to WiFi instead?! That's crazy!
I contacted Google store support team and they have been really helpful so far. They offered to replace the phone with a refurbished unit, but I don't think I am ready to give up on this phone just yet.
Thank you!

I hate to recommend this, but sometimes things go out of wack after a SW update, so a hard reset would probably be needed. I would try that (just start from zero) before jumping into a refurbished phone that might have some other kind of issues. Have you tried a hard reset yet? I see that you did a fresh reset. Did you go through the recovery though? Not just the regular UI. I think it's better to clear cache, and every thing through the recovery (custom or stock).

Is it a widespread issue? Like I said in my post, I saw the decline ever since I got the April security update. The May patch actually managed to make things worse. There seems to be something hidden in the OS that it's draining the battery and causing the awake issues. I haven't tried rooting the device because I lack the experience to do so. I will probably look into it on these forums, but at this point I have tried everything.
Disabling Google now helped a lot and it exposed some sort of a glitch with the stock battery monitoring app. I am not sure if it's hardware or software, but it's certainly not normal. I am tempted to just replace it, but I am afraid that this issue will just plague the new one from Google. I am really disappointed How Google handles updates on this device. I always thought that stock android is most stable version of android, but the software on my old Xperia Z is actually more stable than this. It never had battery drain issues and standby battery life was always great. The battery life on Nexus 6P is actually worse than the Xperia Z even though that phone is 3 years old.

I've seen a lot of posts over the months with people having the same problem we are. I came from a mid range LG stylo with a snapdragon 610. I would have 8 hours screen on time daily. Its sad that goggle cant get the same out of their own hardware. Also I have seen that the Note 5 and S7 Edge both get better battery life as opposed to our stock phones. For as much as people praise stock and look down on Touchwiz, they are doing something right over there.
But it doesn't affect everyone and that what puzzles me. Only certain phones are hit by these issues, while other people are getting excellent battery life. I have seen plenty of people post screenshots of 6 hours+ of on screen time. I am lucky to get 3 hours. I think Google should really invest in creating a better power management system into Android. Companies like Sony and Samsung built their own and the battery life on their devices always perform predictably relative to what I am seeing on this phone. I have never witnessed The doze feature kick in since I have bought this phone. Sony had stamina mode since 2013 and it actually worked.

Most of those people posting those outrageous number root and do kernel tweaks. I've gotten at most 6 hours SOT on stock without root. You are right our phones do all react differently to certain circumstances. I don't know if it's feasible to you ,but you should try rooting and trying out a few Roms some help others don't. If you aren't into Roms and decide to root try earlier vendors and stock roms and see it those work. I'm not an expert by any means just my suggestions.

Well, the fact that you are having great battery life proves my point. It's either that the quality control of the batteries used on these phones are terrible, or that the software or kernel are corrupted from factory causing these issues. There is no way to fix them by hard reseting the phone so far. I am going to try to flash a stock rom on this device and see what happens. Thanks by the way.
1) Are you rooted? If not, at least do that and install BBS in order to track down what's eating your battery.
2) Probably we'll run into a common problem / bug the last two months.
After unplugging the phone, it seems that the wakelock *backup* runs constantly, does not let phone get into sleep, and runs in the background while using your phone causin battery to drain faster.
3) About battery life. Comparing battery results between two users it has no point, unless you really now his usage pattern. Not only the setup, but which apps of them used most etc.
For example Facebook app is real battery eater. I've seen an hour more SOT without this app.
I can give several examples like this.

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.

Yes
Maybe? - another issue?

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.
