Am I stupid? Just tired of the battery drain on nc4... My note 3 used to last all day EASILY.. i had it in my pocket with all apps frozen, location services off, power saving mode on, on eclipse, didn't even look at it and i got 4 hours off the charger . even had data off and had it on airplane mode for the last couple hours as it went from 74 to 5.... It just feels warm and drains for no reason.. no apps... I have heard it's a common issue I just don't see a reason to be on nc4 until it's fixed... Am I stupid or what? I swear that beans and clean rom and the old baja's used to have better service and MUCH battery life.. anyone else done this ?

There was a noticeable decrease in battery life going from 4.3 to 4.4 for me - even with Greenify, extreme battery saving measures taken. But it wasn't more than 4-10 hour difference --- so going from 75% to 5% in a couple hours indicates a huge problem. If I was in your shoes I'd fresh ODIN Bean's 4.4 then flash MJE then go from there if you have a favorite rom. I'm seeing 50% usage in 1 day with medium usage (probably light to medium for most). My dad is also on Bajarom with NC4 and he can get 2 days with 15% left with light to medium usage. That said, I do remember more on 4.3.
Commenting on radios: the problem I have MJE is that I can't get any WiFi throughput even with Radio_Power_Save 0 in build.prop. I wonder if that's why we don't see the best battery savings with MJE - wifi output/gain? is extremely low. NC2 fixed WiFi but I had 0 bars of LTE reception where I normally have 2 - instantly made it a no go for me. NC4 has a very noticeable WiFi throughput difference and better LTE signal - but not as good as MJE. I'd stay on MJE if it didn't make my WiFi completely useless.
Edit: As someone who has had smartphones since Droid 1 - I'm done with the days of trying to squeeze every inch of battery life out of my phone. The Note 3 was the first phone I felt I could use without making it unusable - meaning, using Greenify, keeping the phone off as much as possible, black backgrounds, just made the phone a bother vs actually using it and charging it whenever. So I bought a 14,000 mAh RavPower brick and my backpack has 2-3 RavPower 2.1A chargers (along with my wife's iPad charger) with 2-3 Monoprice cables so I can charge where ever, whenever. Now, I just use my phone as much as I want and when it hits 50% I plug it in --- which is 12-24 hours for me on average. I try to enjoy my phone instead of worrying about battery life.
----- that said if it was draining in 4 hours, I'd take drastic measures to fix it.... Buy an Anker battery replacement - see if the stock Samsung battery isn't going bad? And definitely re-flash everything via Download mode.

Great post man, thank you for sharing. I'm debating 4.4 again and trying it stock then maybe with eclipse or baja. i miss 4.4, but I haven't had a single problem on 4.3 i really haven't... you're probably right about not worrying about it so much and just enjoying the phone. I felt the same exact way, when I was on 4.3 .It lasted FOREVER. Got me through the day, didn't drain while I was at work, etc.... I did get an ankrum replacement, but even it only lasted 6 hours with no use on 4.4..... I may try 4.4 again and just hope the clean instal helped everything..

I rooted and flashed Fresh 2.0d about 2 weeks ago. I have flashed the Verizon radio, and if anything it made the battery life slightly worse. I was wondering if it is a consensus that people are getting worse battery life on fresh than on the stock 1.5 ROM? Today my phone died from a full charge in under 4 hours. I am expecting that I will have poor battery life due to a very bad signal, but it is far worse than the stock ROM. I am also starting to get concerned about the temperature. It has been sitting around 43C all day. I have had it plugged in for over 3 hours and it is only at 7%, which means that it is using almost all the current that can be supplied over USB. I am probably going to try DamageControl if I have time this weekend to flash it, but I like Fresh and was just checking to see what others thought. The battery use thing is saying that over 60% of my battery usage is due to cell standby and phone idle. I recently put setCpu on the phone, will that cause some of what I am seeing? All settings are onDemand with a 528 max and variable mins based on status(lower mins if lower bat or higher temp).

Trying this fix, will update tomorrow when I give it enough time for a thorough test. Thanks...
Update: It works awesome, only 10% in 2 hours at little to no signal and roaming!
I have read many other threads about improving battery life and such but I am still at a loss. My battery in my Epic is only lasting about 5 hours(9AM~1:30PM). I have a moderate signal the whole time and I am using the phone but I only have the screen on about 10% of the time according to Battery Stats(forget where I found this info, maybe spare parts?)
I have turned off Wifi, bluetooth, 4g, GPS only turns on when I open an app that needs it. I really have no idea what I am doing wrong since this seems to be completely terrible battery life. I have also killed the drm service and have found that it did not help my battery life much.
I am rooted and running Syndicate Rom 1.0.2(not froyo since I use a Mac and have not gotten my hands on a pc). I am using Xtreme Kernel clocked at a max of 1ghz.
Any other tips? Should I take the phone to Sprint and ask for a new battery? The phone at this point is only about 3 months old. If this seems to be normal for battery life then I am pretty sure I will be jumping ship and getting a new phone.

Only advise I have is to toggle airplane mode after every boot and switch from the extreme kernel to pheonix 1.43, it has the best battery life by far as will any of the phenix kernels but 1.43 is the best

I got 25 hours of a charge the other day. Had to grab a screen shot real quick before it **** down. Might frame it. On stock dk28 with moderate use, lots of pics...it was on christmas so it was prety well used, trying to escape conversations with in laws.

I'm having the same exact problem. Same ROM and everything. I'm getting absolutely terrible battery life, maybe 5hrs on a full charge. Its ridiculous especially seeing how the nexus s is basically the same phone and gets nearly 20 hrs with no problem. WTF!!!??
Would bet a dollar that your phone is not entering sleep mode properly. Download Spare parts, charge your phone up, unplug it and turn the screen off and wait for like 10-20 minutes and then turn it on and open spare parts and look under Battery History. You will see that it will say Running 100% or something high like that.
This is probably because of something you set up. Either facebook updating every 30 seconds or maybe push email. I dont know.
I pretty much always get at least 24 hours and I work in a basement where I barely get a signal. I leave wifi on all day. I talk for about 20-45 a day on average. I listen to music for a couple hours a day. I play games for a good half hour of my lunch break and sometimes for an hour or two at night. Sometimes I forget to turn my gps off for half the day while I'm in the basement.
I have killed a battery in 6 hours when I spent the entire time downloading and playing games. And I had a battery last 42 hours a couple weeks ago when I was helping a buddy work on a car. We used it to drive some crappy pc speakers for music for about 8 hours in those two days and I spent a couple hours over those two days looking for info to help us diagnose his car.
I have been on Mammon's DK28 for a few weeks and have mostly been on the latest FroYo roms since the leaks starting hitting the public. I ran the same rom and kernel as you guys for a couple weeks, and I don't remember the battery being that bad. IIRC, I was overclocked and still saw 18+ hours of battery life with normal usage.
What are we doing differently? That is the question. Do you have a bunch of widgets and a live wallpaper? I don't. I try to keep my widgets pretty minimal. I have TWC on one screen, a flashlight widget on my main screen, and Pandora and PowerAmp on a third. I generally use a pretty dark wallpaper, too. Something simple and easy on the eyes as well as the amoled. I also keep my wifi on and set it to never sleep wifi. Why? So it doesn't search for a 3g data connection. I have wireless networks I can connect to in the places where I spend most of my time, so I might as well use them. Sure it has to power up the wifi radio, but the wifi radio seems to use very little power when you're sitting somewhere with a good signal. Also, read "How to Train Your Dragon" in the dev section. I have three batteries and generally reset the battery stats on one of them every two weeks. If you only have one battery, every 3-4 weeks is suggested. I always charge my batteries in the charger and almost never plug my phone in (because I don't have to) and about half the time I bump charge the battery after it is finished. Be careful with bump charging as it can reduce the number of charge cycles your battery can take, but can net you 10-15% more capacity in the short term. I rarely discharge my batteries below 15% except for when I'm recalibrating them. If you discharge your battery to too low of a voltage it can reduce capacity. And if voltage is reduced too low, it won't charge at all, but may be fixable with a cadex machine.
Be sure to go find that thread on how to train your dragon. There are some links in there that will teach you a good bit about how lithium ion batteries work and what you can do with them. After that, you need to see what is running on your phone to use that much battery. Is some process or group of process eating your processor?
edit: Look Mom, I wrote a book!
I will try changing kernels and updating to froyo(maybe hijack my dad's netbook).
If this doesn't work then I am going to go to sprint and see if they will swap out my battery. I tried the thing with spare parts and it says time running is 18% since last unplug which seems a bit high but not too ridiculous.
I have read and followed the instructions in how to train your dragon. I am really starting to think it is a faulty battery. I will report back, thank you everyone for the advice.
ok, thank you all for the advice. I am able to get through a whole day now on a charge since changing to Phoenix. Maxes out at about 10 hours as long as I am not constantly on it.
Updating to froyo later today.
Not really going to be helpful for you, but just my observation:
DK28 has MURDERED my battery life. Lots of people have issues with DK28, but the GPS, accelerometer, etc but all that stuff works fine for me - the only problem is the mega hit battery life took.
Let's hope the official release isn't as bad.
DK28 probably murdered your battery life because you forgot to do one of the battery saving techniques that you were using on your previous DI18 rom. Pretty much everyone else is seeing battery improvements with DK28.
I don't think so. I never use GPS, 4G or Wifi and I've always had the brightness auto adjust on.
hi
this is not question, just more a thought
now i have read on several post on different forum, about the battery drain on the galaxy s 2.
and my big "concern" is why is there sooooo big different on the battery drain. some people can last for 2-3 days and some only 5-8-10 hours. from what they are telling they are using the phone almost equally..
for an example this first post here, he still have 50 % left, although he saw video,playing , surfing and call http://forum.xda-developers.com/showthread.php?t=1055164
mine last for about 10-12 hour with moderate use.. and i have killed all unused apps/task/services, wifi ,only 3g, low brightness, wipe batt state.. and installed villainrom
it sounds to me that some people get a really good phone/battery and some not.
Everyone's idea of light, moderate and heavy use varies. It really only comes down to a few major things. How long the screen is on, how often the device is awake, and how intensively the device was operating while awake.
If people know what to do (search the bloody forums for a start)they can achieve good battery life, too many fools are too quick to come on here and complain about poor battery life without even searching the forum, also anyone who gets 2-3 days clearly isn't using the phone that much, i usually get a full day out of medium/heavy usage and you cant complain about that, this is a smartphone and if people are that obsessed with battery life i suggest they use an old Nokia

Very true. I can easily get 2-3 days if I just used it for calls and text.
Heck, I can get it to last 1-2 weeks. Just put it in flight mode and don't touch it except every couple of days to check %.
Why people don't just buy spare batteries is beyond me. I bought 3 spares + a wall charger off eBay for around $10. When I'm low I just pop the used one in the charger and replace with a full one. From 0% to 100% in 30 seconds. I even leave one in the car in case. Did the same thing with the S1.
BTW, to the OP why leave it on 3G? I'm assuming you switched off H. For me I use the 2g-3g widget and select GSM only. When I need 3g/H for data I turn it on.

My 2 cents
I will tell you this. For what its worth.
I've had 4 friends get the GS2. 2 of them are white, 2 are black (the phones, not them.)
In all four cases with the stock ROM They came and complained to me how they love the phone but the battery dies before they can get home.
All four cases I've done this update for them via ODIN
- ROM Update: XWKI4 (UK XEU, android 2.3.4 to support google video chat)
- Kernel: XWKJ3 (stock)
- Modem update: XXKG5
Each and everyone has told me they're getting literally exponentially better battery life, snappier response and stable usage.
Take it for what its worth. But i recommend your combo.
I think usage pattern is definitely important but i've experienced idle drain and gone through months of struggling with this. not all roms/kernels have the idle drain issue. The above combo should work well for you. Good luck

Well there are differences in software and usage, but thats it. use a clean up to date rom, good kernel and do not install crappy apps like facebook which drain the battery. Using a modem which suits your provider does make quiete a noticeable difference, especially with hspa activated, idle aswell as using the data connection. Battery life of 12 hours or less is clearly a use or apprelated problem.
Note3 running Beans stock 4.2.2 rom. I've removed/disabled a lot of the system apps/bloatware and run a couple xposed mods (in pic below). Phone was half on wifi half on good 4G; also in good service areas entire time. GPS off, automatic brightness. I only get 4hrs of screen time and total running time is approx 8hrs with 15% left. I think this is quite low for a 3200mah battery. Anyone give me any suggestions to prolong the battery?..or reasons why I can't seem to go a full day?
...I posted this because my bro has stock nonrooted S5 with high brightness on whole day and can easily go 1.5 days with same on screen time so I was lil disappointed in my note.

you have something keeping the phone awake or chewing the battery...most note 3 get about 15-25 hours per charge... i keep my brightness fixed at about 25% i have greenify now it seemed to help.
How do I check what it is? I'm not sure what it could be but know that 15% with 8 hr total battery time and 4 hr screen time that it's a little under what I expect out of a note3.

solution to low battery life
It doesnt seem to be a problem since my old note 3 had the same battery life.
A tip ill give u is to try to turn off the wifi every while...
And also try to use this app: screen filter
It reduces battery life by lowering the brightness.

I have similar issues however I get a little better battery life as I have basically turned off every good option on this phone in order to make it last . Ive concluded that this phone has terrible battery life due to Android 4.3 and higher sucking up the battery unnecessarily .. the background processes are endless and truly destroy the daily longevity and options of this phone. Take a look at the Note 2, same battery, different operating system and more or less same hardware and out of the box the note 2 lasts WAY longer than the note 3 (at least from my own personal experience). Frankily, if it was possible, I would love to downgrade to 4.2 (or 4.1.x) to see how significant of a change the battery life would be. Thats my 2 cents

that just adds more evidence to my theory... the android 4.3 OS is a battery sucking operating system when it doesn't really need to be.
I never had a problem with 4.3. I was running hyperdrive 4.3 with greenify, v6 supercharger, and a crap storm of other tweaks and xposed mods and with very little usage (didn't take a screenshot of screen on time) I was at 5 days 13 hours 43 min with 6% battery left. I tried to update to hyperdrive kit kat and had nothing but problems so I flashed stock nc2, upgraded to nc4 modem and have spent the last week (couple hours a night) modifying and tweaking. I'm currently at 1 day 20 hours 13 min with 4 hrs 15 min screen on time and I have 19% battery left. I would probably be closer to 25%-30+% but last night I decided to go all out with the cpu control and run antutu benchmark twice to test different I/o schedulers.

So do you think with a custom ROM instead of being on stock 4.2.2 will help me get more outta the battery?

Probably the first step would get better battery stats and find out what is draining your battery. Freezing app apps won't do much to save battery if your not freezing the ones draining battery. Also look into greenify you can hibernate apps that you need installed and to run frequently but can put them to sleep when you don't need them
Also I got rid of V6 and decided to do min free and kernel tweaks manually with Rom toolbox pro. Not sure if a fluke but currently I've had 2 hours of screen on time and only dropped 20%. That's as much a 10 hours screen on time on a single charge.

Did you flash to stick slot and flash nc2 before flashing hyperdrive or were your issues some menus did not work if so those have been patched and everything works now.
I had wakelocks that lagged my phone (500k+ in twelve hours) and ran the batter almost dead in that time. Yea I flashed nc2 upgraded to rsl8 and updated the modems. Just didn't feel like trouble shooting anymore and with xposed I can have everything I want and biting I don't

hello everyone, I'm a new note owner, I bought it used and I think it has two years on it, but it is in great shape. I noticed however, that the battery life isn't that amazing as people have told me, this coming from a Galaxy alpha user. I will leave screenshots of today's battery life and I think it isn't that amazing what it got
I've heard about battery miscalibration, is this really a thing? I can try and calibrated but I need to root it, & I wasn't really looking forward to reading it, since its lollipop on stock rom.
The screenshots are bellow of screen on time and total time, you can see that it's not consistent and I charge my phone two times a day.

I'm using lollipop official rom flashed on Odin via download mode, yes the rom is compatible with my country's frequencies so there's not really a problem there.
I notice however that the battery sort of goes down faster sometimes more than others, sometimes even going as far as draining 10% simply being on stand-by with LTE enabled for 2 hours in my pocket when I'm in class.
Is this normal behavior?
I don't think there is any such thing called miscalibration, I mean I am not sure, but well.
If your phone is 2 years old, then I think the battery has seen its life, time to get a new one mate.
Battery recalibrates itself .
However as the battery is old then Drain the battery to 5% power off charge fully unplug wait one hour top up charge and use .
Next step is new battery Anker brand is good .
Wiping battery stats/ supposed calibration has nothing to do with battery calibration and will make no difference .
Lithium-ion batteries last about 300-500 charging cycles, after that the risk of it dying increases exponentially. Some last 5 years, some 1. It depends on usage and environmental factors.
There is no such thing as recalibrating a modern lithium ion battery. It doesn't have a memory.
New battery costs about 20 quid, it should solve the problem.
Also, did you do a reset after the update? Updates can cause battery drain too, quite often.

No, I did not do a reset after the update. But I noticed this before updating to lollipop, I had to do some running around before I got home the day I bought it, and it was running KitKat 4.4. I got it with 93% of battery, walked home for a bit and was down to 65, went to the shopping and back, got home with 40 to 35%. (I bought the phone at around 5 pm and finally got home after going to the mall at around 8pm)

Then it's the battery, most likely.
