My Battery drained from 100% (it was fully charged, then I unplugged it and locked it) to 75% overnight.
What are some likely causes of this?
I noticed you have no signal. Constantly searching for a signal will drain the battery...
I've only had my N4 for a few days but the battery life has been good so far. A couple of brief observations...
1) On wifi only overnight (no SIM as I just got it and didn't have a micro yet) for 7+ hours. ZERO % drain...
2) On LTE (2-3 bars) for the past 3 hours. I left the phone and came back later. ZERO % drain...
Gmail is push, no GPS or BT. Only core apps running. I don't normally have anything in the back ground outside of lightflow...
Download GSam battery monitor
I noticed this also. I never had that much drain with my Galaxy Nexus.
I went out to lunch. Sent a few texts with google voice and looked up some random food articles on wiki for a few minutes. I was gone for 1-1.5 hours and now my battery is down to 47% from 75% this morning.
I'm going to download GSam and see what I get from there.
Edit: Installed GSam.

Charge it fully tonight, unplug it in the morning, and then post your GSam results tomorrow night after a day of usage.
Mine has started loosing charge overnight too.
It won't turn of wifi when asleep either. Since I activated Google Now.
Mine lost 5%in 4hours overnight. Nothing running apart from mail and now notifications.

Your android OS usage is terribly high. That's my first suspect.

My android OS usage is very high as well... sometimes higher than the screen. I'm gonna try turning off google now to see if that does anything but other than that I have no idea what would be causing that...
The screenshots show app usage as being 50%+.. It is probably a rogue app you have running in the background.

As I said before, I believe it's some Google apps, I deleted a bunch of Google apps I don't use. My phone sleeps like a baby now. Overnight it only went down 2%.

I had the same issue for a couple of days. I would wake up to my phone only having 65% charge and the device would be rather warm. In my situation, I found that the charger was faulty. I noticed at times it would cause the phone to flicker back and forth from charging to in use. Lucky for me, I don't sleep well at night and I found the issue after my phone had been plugged in for 5 hours in the middle of the night. With that said, I also noticed the charger would make a high pitched hum/hiss. I swapped my charger out for my old Iphone 4 charger and I haven't had an issue.
Nearly a full day's results.
I left my phone charging from night until morning. I unplugged my phone sometime around 10-11am and I stepped out around 12:30.
It's 5:52 pm now.
I was out from around 12:30 to around 5ish. At around 5 my phone had 50-56% battery left. My friend's Iphone 5 had 75% left. Aside from my friend using his iphone as a GPS to navigate in the car (around 20 minutes) - we had roughly the same phone usage (by my estimate of course), we were at same locations and both of us are on the same network.
To be frank, I don't understand why my friend had more battery life than I did considering he was using gps. I do feel like there is something draining my phone battery.
My screen light settings are on automatic.
I've attached GSam and my list of applications.
From about 5 to now (5:52):
After a bit of surfing, installing 1 application to list my apps, emailing that app list to myself screenshotting the relevant data and emailing those screenshots to myself over wifi. I'm now down to 39%

3 hours and 20 mins down the line.
I'm at 10% battery.
Is anyone experiencing weird issues with battery before recharging? i had 2 days phone on batt and 3hrs screen on. It was at 53 % before i decided to charge. I fully charged it and now im losing 10% every hour even with phone on idle. Its weird cause every other charge will last a long time.

Yeah, I'm still stock on this phone and I'm getting inconsistent battery life. I usually charge every night, so I'm running about 16-17 hours per day. Almost identical usage each day but one day I'll plug in with 45-50% remaining and the next it will be dead when i plug in. Very odd. I'm going to root this thing just so I can get rid of the bloat apps. Well, that may not be the only reason I root. I may be compelled to put some AOSP on this and see how it rocks it.
well i don`t really recommend to ROOT stock rom, it caused for me a battery drain ! also KitKat known for drain issue even on Pure android on Nexus 5. I don`t really know a fix but i`d give u some tip and it might help
1. Re-flash D80020c
2. After re-flash do a factory reset
3. Don`t root or mod your OS
4. Turn off Sync or Location Service (or set to battery saver mode)
i did those steps and i have 34 hour on battery:
3 Hour screen on time (and about 30-40 min gaming in this 3 hour)
Left about 49%
i hope i helped a little
Potential solutions:
Have a look in Settings > General > Battery and see what seems to be using the most power. You could have a problem app that’s using GPS or trying to update frequently. If you can identify the culprit then you can remove it.
There’s a slim chance you have a faulty handset. If adjusting your usage and tweaking settings doesn’t’ result in any improvement then take your LG G2 back to the retailer or carrier and get a replacement.

I always have location turned off with all bloatware rwmoved. I honestly think you have to drain it to about 20% then charge. Cause i never have problems when i do that. Gonna try and drain it out again and recharge and see what happens then.
Are you having issues on KitKat out jellybean?

Its kitkat,it says rooted d80020c in my signature. Well here is my latest results. Left it on overnight and was at 53% with data off. Checked it this morning and everything was back to normal again no battery drain or low estimated battery times.weird cause i charged it around this percentage. I think you have to take it down to at least 20 before charging will find out later today when i charge.

well i really not heard about Deep sleep drain but while idle it`s drains bit faster then JB, with jb i could get max 40 hour and about 6hr screen on time and + 10-15% battery while on KK i can get 42 hour but about 5 hr and 45 min screen on time with 0% battery it`s seems a bit problem for 4.4.2 i think Google will fix it and hopefull we`ll get new update from AT&T if this prob will fixed
P.S i saw that if battery at 100%, overnight it won`t fall to 99 but while battery is on below 100% it drains about 1-2 % overnight is that a known prob?

2% overnight is pretty good, given that it's on WIFI I'm assuming?
I lost 25% overnight last night when I was off WIFI, so I factory resetted mine.
Took it down to 20% and discharged and its fine. Im guessing its a bug,but, easy fix just take the battery down to 20% or lower before charging
When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the Note5's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!
I'll test this later today. Charge my phone to 100%, and right before I close my eyes, I'll unplug and see how it does. I'm curious as well.
Typically 0.5% per hour or less with lots of bloatware disabled (200+ apps). Couple gmail accounts, s note and scrapbook syncing.

So I unplugged my phone when it reached 100% and got a notification saying the battery is fully charged and unplugged it at 10:40 pm. About 7 hrs and 20 mins later, my phone dropped to 93%. That's about 1% every hour. My phone is stock, no root (yet) with 17 apps disabled. WiFi is on, brightness was on the lowest setting and all accounts on my phone sync through the the night.
I've never done this with one of my previous phones, so I can't really give you my opinion on how I feel about this. Let me know what you guys think. I'll try disabling some more apps and doing the test again and see if that has some effect.

if you are rooted and have xposed. download Mobileactiveradiofix...bassically some apps you are using that utilize mobile data, after you turn off the screen it still using data....thats the gist of it.
Drain about 1% per hour.
Tried 3G all the way. Not much savings compared to LTE all day
I have the 920CD Dual sim. Horrible Battery standby. I lose 2 - 3% per hour on android system usage while i'm sleeping.
I tried disabling apps etc but to no avail!
During night my phone consumes up to 30% of battery, my stand-by is 16hrs at max!!!. I love my phone but there is an obvious problem about it.
On the other side my wife has the same phone and her battery withstands up to two(2!) days.
(Hers is running on stock firmware with simple tuning, mine is also on stock but i checked and disabled almost everything)
My phone is ; N920CXXU1AOH2 hers is N920CXXU1AOGF. Is there a way i clone her phone firmware and copy into mine?
I think you guys above may have Wakelock. Mine started up recently and it drains up to 15% of my battery from just a bit under 2 hours. Before that it would be fine. Unplugged all night (8hours) and lost 2-3% battery
I couldn't believe this rating was so low. This is the best at standby. Absolutely phenomenal. It's literally around 1-2% an hour. I can get home after 11hrs and still have 70% left. Usually it's around 50% with 2 hrs of screen on time / use.
Got an update yesterday. ..it includes the doze feature from marshmallow. ..vastly improved the standby time
ścribbled from my Note 5
I wouldn't call 1-2% per hour idle time phenomenal, It's average at best.
0.5% per hour (or 2 hours per 1%) I'd say that's very good.
3 hours per 1%, that's excellent. This happens to be my Xperia Z3 Compact's idle time when I sleep.
Phenomenal? It would need to be 4 hours per 1% idle time.
My Note 5 is doing 1% per hour currently.
My iPhone 6s Plus can go over 7 hours standby and still be at 100%. One of my biggest peeves with Android was battery drain. Just switched with the release of the 6s and am very happy. Had the Note 5 and still have the Nexus 6. The doze feature still can't even come close. And it only works if the phone is shelved. Not in the pocket. Not good enough for me.
Please everyone who has the drain, write samsung feedback on their support website. It is most of the time caused by the wlan_rx_wake, wlan_cntrl_wake and wlan_wake wakelocks. I am trying to find a fix but so far nothing has helped me except turning off wifi.

Really? I can live without WiFi most of the time if it helps my battery.
I was getting great battery life, I stopped using the Note 5 for about 3 weeks while I reviewed some other devices and when I return I'm loosing 5% an hour, doing nothing. I've done a factory reset once, slightly better, but still not great. Might try another tomorrow.
Let us know if you find a fix.

just like you .. I come from a s6 and did not have this problem, hopefully be resolved soon
During night, I switch off mobile network and wifi, but both SIM still active for phonecalls. Drain this way is around 0.5% per hour or 3%-4% per night - depending on how long I sleep
Frankly, I only used the phone with the latest update so, I have no idea about battery performance before it. Anyways, I'm getting great overnight battery performance, with 3% dropping in 7-8 hours (mobile data, wifi and bluetooth off).
all data and BT off and you're dropping 3%? Turn your phone off and you'll drop 0%
Mediaserver, system and kernel kill my standby. Is it worth factory reset or should I hang out for marshmallow?
7% of battery overnight.
Wifi, 3G, google now and side clock on.
Is this normal?
Standby Cell=2% (5h on time)
Android OS =1% (13m cpu)
Standby Device = 1% (4m cpu, 28m active)
I too loose between 5-7% overnight (8 Hours). Although the battery life of Edge+ is pretty good while in use, I have noticed that standby of the device isn't as impressive as earlier Note variants (Yes, I'm comparing with Note series).
WiFi - ON
Auto Sync - ON
2-3 Apps with Notification ON
Samsung Pay on Screen Off - ON

Your CPU seems to be idle 95% of the time! I never checked mine but yes, mine drops that much too! I don't think that's a rare case with this phone!
Ok so it is good right?
Then why it drains so much overnight?
Depinding on my signal strenght ,i saw -10% overnight ,ok maybe i slept like 10 hrs insted of 7-8 but still . Battery info said that the juice went to Cell signal standby or something like that.

yep, same here... so maybe it depends on the strength and quality of cell signal..
will test in the next days...
I am sure it cannot be any samsung app/service as I have disable 200 of them with package disabler pro
also, location/3g/wifi/sync/googlenow always on is the same setup I had on OnePlus One, that was using barely .5% per hour
it also true that on the OnePlusOne I could also turn off the notification light during night, while with this I cannot so it could happen that the light keeps on flashing for 5 hours, draining battery
also, I have edge clock on at night, still some drining...
I thought the deep sleep or idle drain was caused by lollipop, no? I lose over 10% from a 7hr sleep, even if I turn the WiFi off. WiFi eats up a lot of my battery for some reason, and I know my connection was good too.

It's been 5 nights and I confirm it drains 1% per hour.
This is my usage really bad...
8% in 6h
Night clock on
Wi-Fi on
4G on
Sync on
I received 5 emails so notification light has been blinking for almost 5h
Don't understand, cos stats are not that bad...
Think yourself lucky. I'm losing 50% overnight.
Battery life impressive during the day though

I solved my problem: night watch...
With night watch on I lose 1% per hour at night, with night watch off I lose 2% in 6h
I was consistently losing 2%-3% per hour overnight. But once I found an overactive app (Plume) and changed from instant notifications to 30 minute polling, my battery life has drastically improved. I've also used Package Disabler to disable bloatware on my device.
The past couple days my battery has been around 97% - 98% when I wake up in the morning.

Drained 10% in 9 hours
I have my new ROG Phone II drained 10%(93% -> 83%) in the first night (9hours). Without battery saving mode, wifi and GPS turned on. Facebook, twitter, whatsapp and telegram running in the background. Is this normal?
Its a lot lol, it should not discharge more than 1-2% over night but you kept everything enabled which is a stupid move.

Seems to be within expectations, but you could improve the time with few tweaks.
Standbydrain over night is very low, does not even drop 1%(!!) WiFi/data turned off ? (I use Naptime to force doze)

Mine drained 10% with WiFi, data and Bluetooth off in Super Saving mode. I wonder if its due to poor mobile signal reception inside my home cos if I turn on Airplane mode overnight, I get only 1 to 2% battery reduction.
Check what app is use power. I got rog and problem is google play service - in my case use about 23-25% from charge to charge.
This problem is not in this phone but others also. We need to wait till google or Asus go and fix it.

check whether the google photo is running at the background. this happened to me, when I migrated from my old phone, when I run the google photo, it seems that it will do a lot of thing over the next few hours in background until the OS kill the process off.
drains 2-4% per h if you disable everything from stock, so whats the point in have this phone if u berly use it if the phone dies in few hours
Not much to say. Hardly any really
I have the ambient lock screen on. So there's always a clock showing. Went to sleep last night, leaving wifi, data and bluetooth on, at 88%. Woke up this morning after 5 alarms and notifications throughout the night at 86%. Was asleep for around 8 hours.
I just had 8%drain over night (6h). The only thing I changed recently was system update from 44 to 64 WW. That's up from previous 2% over 8h from ww.44
Battery is the worst ever. My Sony Xperia 1 with 3300 mAh battery is better.
Google services finishing off 45% of my battery always. Tried everything nothing works...
My standby drain is back to 1-2% over 8h once I rolled back to WW.35, so if you are having worse standby battery life on WW.64 you might wanna roll back too.
This was not Google services related, I had like 1% max of Google services, there is something weird with WW.64 for some users about that specific drain.

I just flashed the RAW WW.35 like it was an update, but in my case I was coming back from GSI rom (with WW.64 base), so I had to do a factory reset too, dunno if that's going to be the case here.

I had 1 or 2 % over night with WiFi,gps,4G and notifications ON . I disabled the Optiflex and now I get 0% .Went to sleep at 70% and woke up at 70%. Was asleep for around 10 hours .
10% for 9 hours is normal.its around 1.111% per hour.so approx 1%/hour...with 100% your phone can last for 99 hours.

10% drain over 9 hours (over night?) is not normal.. Unless you had 4G turned on and a bit bad reception.. ? With WiFi and 4G turned off at night, it should not drain more than 1-2% MAX over night (10h). Mine usually drains 0-2% over night
