It sound like you have a faulty battery if it only lasts three hours, I think you would have to be gaming to flatten a good battery in that time.
John.
Mine is the same. If I'm browsing the web, using instagram, Facebook and receiving email my battery will go from full to empt in easily 3 to 4 hours.
Backup, factory reset, reinstall apps from market (try to install only the ones you use a lot at first), restore the data you need. If you're still seeing the same things happening, install a battery logger / system logger. Use this guide to see if there's a rogue app that's causing the trouble: http://forum.xda-developers.com/showthread.php?t=937080
If it's still acting up and you cannot identify any unusual drain, I'd ask for a replacement.
After you get things sorted, you can use apps like Juice Defender from the Market to prolong your battery life even more.

thanks guys for the sincere contribution.... i hope your advices help me...
my top battery consuming activities are:
temple run
google play
msging
go launcher
and nothing else
gaming and browsing certainly make the battery drain almost visibly..
things above and beyond the above to try include..
1. reduce screen brightness
2. reduce frequency of or disable background updates by apps
3. no vibrate notifications
4. work more, play less!..lol
the battery life of the Note is great, unless you use it .. a battery monitor will allow you to see the battery drain over time..this will help when you address item #2 above.. if you accept default refresh times, and have lots of social apps your battery can die in 6-7 hrs without even using the Note at all!..
I really love when people give the tip to not use your phone as a battery saving tip

some hints for better battery life
Got mine the other day. First charge battery was fine. Second charge went down 7% in about 5-10 mins. Then it restarted :/ Came back on, down to 88%. Turned the phone off as was frustrating me as it restarted 3 times yesterday. But when I turned it back on I was at 83%?
Hasn't last me the day, it's on charge now. When it pops up telling me to charge it tells me to shut all apps and that using while charging may effect it charging. Is this correct? I didn't think it would have anything to do with it?
3 to the 4 hours continuous use is normal... Only if your phone is standby and then depletes in that time You should be worried. I recommend researching wakelocks in that case.
There are many variables that can atribute to batterylife depletion. Eliminate those first and you will have your answer.
I had best results on stunner version 19. To bad it has the death kernel (leaked ics)

I am facing a similar issue, facing a massive wakelock by PowerManagerService. It keeps the phone awake all the time?
Any suggestions?

Usually that wakelock is there cause you are charging, or have USB plugged in

Had the note for 2 days. It came with LA4 FW and updated via Samsung Apps for the latest FW.
Battery drain, that was none on LA4 became very strong!
Installed Better Battery Stats and discovered that the CPU was always running.
Factory reset solved it...

Hi,
I have the galaxy s4 for almost 2months and now it has an annoying bug -
I have more than 50% battery and sometimes it get stucked (freezed) and restart itself, and he is failing to reboot until I plug him to the charger.
When he boots up it says that it has 0% battery, even though it had more than a half before it happened
What should I do?
Dead battery?

Battery Is fully charged. As soos as I unplugged it. The warning appeared. Battery Critically low. Wtf. Phone is less than 2months old.
This only happened twice. Then I let the battery drain completely and recharged it completely. Now it seems fine.
Samsung.....no words.... :thumbdown: :banghead:
I had a friend who had the same issue, recovery showed a correct value.
Anyway, I took off the back cover and the battery was swolen, he got it replaced under his carrier's warranty the next day.

To recalibrate the battery go to the dial pad, and input x#0228# and a battery status screen will pop up, giving you some information about your battery and such, tap the Quick start, the screen should go off, then come back on might have to wait few secs. and you will notice your battery % might of changed. try doing it a few time until the % stops changing and give you a "real" battery %, then fully charge the battery. should fix any glitches with the battery being read incorrectly. if it doesn't work might mean your battery had it!
From my experience my battery was on 60% after few hours of use, then I recalibrated it and it went down to 20%, fully charged it now my battery lasting a lot longer than before
At least do a battery pull. Don't bother with apps and scripts that wipe battery stats. Do a pull, inspect for leakage, swollen , or damaged areas.

my bad, was *#0228#. Late night!
Well something is definitely up with my phone and this is nothing like any of those "poor battery life" posts. I'll just get on with it. So recently (the past month or so) my phone hasn't been charging normally, i noticed that the little lightning bolt to indicate charging at the top of the phone would disappear and show the battery percentage every 3 or so seconds. It did this and thought it was the way I held the phone, maybe I had a slightly bad charging port that disconnects with the slightest movement. However today I set the phone flat and watched the same phenomenon happen without any movement, every 3-4 seconds it would say no charging like clockwork, but there was no charger disconnected notification... On top of that my battery life is the worst I've ever had to witness in my short life (ill post a screenshot below). With certain chargers my phone will only charge when completely off, and last night i left it to charge while idle and it only charged to 50% after almost 12 hours continuous charging! Any ideas? I hope its the battery and not any other software or hardware problems. Also the battery shows no sign of swelling tho when idle the temperature sits at around 37 degrees Celsius. Brace yourself for these screenshots...
Screens: http://imgur.com/dgfLpTM
Could you post the screen prior to the one you posted, showing the percentage per app? It may help find the culprit

It's possible either your charger, your battery or your hardware itself is damaged.
sorry to be the bearer of bad news.
Also be careful of in-proper charging on phones.
Lithium burns / explosions are not funny.
Okay, so. I would first try to go back to complete stock and try testing again. If it still happens, try changing the charger/cable since you probably have another one laying around anyway. Then I would change the battery, and lastly the device. Good luck.

Are you sure? S4's battery is 2600 mAh. It should take about 15 hours or more to make the battery become low with minutes of gaming.. I have S3 mini and its battery is 1500 mAh and it takes about 12 hours or more to make the battery become low.
I can get 5 hours on 60 percent but I gotta be using battery saver with data off when I lock the acreen

Gaming or watching movies will discharge your battery in a few hours. 4,5 or 6 hours max. Depending on what you're doing and other stuff like wifi and screen brightness.

Was the battery life always terrible or is it just now?
I'm having a similar problem so I'll use this thread instead of creating a new one. I hope you don't mind.
My battery is draining at a rate of 15% per hour even If I leave it on standby, ocasionally turning on the screen to get a message on Whatsapp of checking the time. It was 100% this morning, 1 and a half hours later, 74%.
After reading on the forums that the cause of the battery drain could be that the phone was constantly trying to get network signal (in cases where the signal is poor, like where I live), I decided to switch on airplane mode. To my surprise, in 3 minutes after this the phone was in 75%. 10 minutes later and I got a 76%. As I write (on PC) it is on 80%.
That's right. The phone started "recharging" without a cable (I know this is impossible, just describing what the display shows me) after I turned on airplane mode.
Any ideas about what might be going on and how can I solve this?
Thanks in advance!
P.S.: It's not the battery itself, as I've bought a brand-new, samsung original battery and the draining was still the same
EDIT: the battery started behaving like this only a few weeks ago. So I'd assume that the signal problem could be helping, but would not be the main reason on why my battery goes down so quickly.

Not tried the airplane mode, but i'm sure that if i put to charge it charge quickly, too quickly.... like it was 80% 5 min after 90%

You could try that and see if it is a rom problem.
Otherwise try to borrow a battery from somewhere just to be sure it isn't the battery.
Hi everyone!
I got a Note 4 a few days ago and it has battery issues.
I got it second hand online from a guy I don't know. I'm from Romania, I think the phone is from the UK, it's Verizon branded. The model is SM-N910V and the Android version is 6.0.1. It's not rooted. I noticed this V version isn't very common.
The battery that came with it was pretty poor, it would drain in a few hours with minimal usage and the worst problem is the phone would suddenly shut down at about 30-35% battery life. Then it would go into a booting loop, without being able to actually boot until I plugged it in.
I bought a new genuine battery from a popular online store here (F64), battery life is better, but still with just wifi, it went to 50% in about 2 hours of browsing. Without wifi or data (very little), it lasted for a day and a half. But the phone suddenly shut down at 8% battery life, again going into a booting loop, without being able to actually boot until I plugged it in. I'd also like to mention, when the new battery came, it only had 4% battery life left (I heard they should come about half charged, is that true?) and also there were a few reviews from people who had to try multiple batteries from this store until they got lucky with a good one. Both the old and the new batteries look identical, I don't see any signs of counterfeit.
Should I return the battery and try a new one? Is there a chance there's something wrong with the device itself?
Thank you very much!

Return the battery.
The seller store the battery in a very poor way.
Lithium should be kept at around 40% charged if you store it for a long time (more than 1 month)
I have 5 batteries with me, 3 of them are considered broken (70 - 60% left)
The last 2 are still in very good condition, around 98 - 99%
About your device, you will need around a few days of charge cycle with a good battery.

Thanks for your answer. I didn't know batteries for this phone are so problematic.
I just charged it to 100% slowly from my PC, will use it normally and see how much the battery lasts and if it shuts down again. As I went through forums, some people say I need to do battery calibration. If it's still bad, I'll return it.
Thanks again!
Try to get a battery direct from Samsung. Failing that buy a PowerBear or Anker. Do a factory reset and calibrate your battery by fully charging it, then running it down to 0% (if it shuts down, keep turning back on until it won't turn on). Then charge fully back to 100% again - DO NOT USE FAST CHARGE.

I will look for a store somewhere. I don't think I can find those two brands here.
I did a factory reset when I bought it a few days ago, but that was with the old battery. Will do the factory reset after I drain it to 0% later today.
I don't have a 'fast charge' charger, and I have it disabled in settings.

What I said before is for all phone that uses Lithium Battery.
Lithium Battery must be kept in a storage at around 40 - 80% charged & must avoid hot places if you don't use it for a long time.
Draining Lithium Battery to 0% will deteriorate the battery faster so it's a big NO.
Calibration is done on the phone not the battery.
Delete "batterystats.bin" to calibrate the battery gauge.
Calibration is useless if the battery is bad (you received it at 0% it means that the storage condition is bad thus the battery is bad.
Charging from PC is a BIG NO as USB port on PC only provide around 500mAh & usually it's unstable.
The charging rate is too low & it could deteriorate the battery faster too.
And the last....I think factory reset doesn't necessary reset the batterystats.bin, so you have to delete it manually if you are rooted or follow this link if you are not rooted.

Hi, I didn't return the new battery after all, I think it 'calibrated' itself after the first charge. Also it goes from 100% to 1% and shuts down properly now.
I did two tests on full battery:
- barely using it, no wifi, data etc, just a few short calls (probably 30 mins of OST) and it lasted almost 6 days
- stress test, wifi and data on, gps with maps and waze on, maximum brightness and and a very long youtube video playing constantly (screen on) and it lasted about 5 hours and 30 mins
In normal use it lasts me about 2 days, but it slightly worries me that if I keep mobile data on all the time it only lasts until the end of the first day.
Would this be considered a good battery life for the Note4?
Thanks to everyone for replying and helping!!
