While I am sleeping:

0.8%/hour when wifi/bluetooth AND synch are on, in a period of ten hours, using GSAM.

0,6% or even 0.5% (!)with everything here above off.

But not in medium power mode. I do not think there will be much difference, because device more or less sleeps.

I will try that later, I used medium 100% of the time with my note 5, quite some difference.
[Samsung Galaxy Note 8 Real Life Review] behemot24:
Heavy battery drain

Mine is dropping from 100% to 75% in ~7 hours, while wifi and data connections are off.

Any ideas about how to find the culprit please?

[Samsung Galaxy Note 8 Real Life Review] behemot24:
Here it is.
[Samsung Galaxy Note 8 Real Life Review] MACHEK:
I'd do a factory reset and reinstall everything, something isn't right for sure. I usually have everything running and still only get a 1 or 2 percent drop while its sleeping
[Samsung Galaxy Note 8 Real Life Review] MACHEK:
Or get GSAM battery and follow the adb instructions and see what's killing the battery

Avoid resetting the phone after doing the adb thing, I did and they now those stats don't show in gsam. I started a new thread to ask if anyone figured out a way to get the adb command to stick but haven't heard back yet

Edit: actually it all came back after a full charge
[Samsung Galaxy Note 8 Real Life Review] purchasedPhone:
I have the exact same issue. 20-30% drain and <5% shown for battery usage
[Samsung Galaxy Note 8 Real Life Review] Alex---1:
Love the battery life of this phone.

AOD is on, WiFi always on. Mostly full brightness but reduced in the evenings to around 20-30%.

No packages disabled.
[Samsung Galaxy Note 8 Real Life Review] masi0:
very impressive
[Samsung Galaxy Note 8 Real Life Review] purchasedPhone:
today I was only able to leave it off the charger for 4 houes after it full charged.

100% in airplane mode nothing activated, lost 2% of battery an hour. please help

aod off also
[Samsung Galaxy Note 8 Real Life Review] behemot24:
Do you happen to have the dual-sim model too? I think maybe this is why my battery is performing so badly.
[Samsung Galaxy Note 8 Real Life Review] purchasedPhone:
no, I have snapdragon sprint model. if we can't discover the issue in the next few days I will have to initiate a return ?

have you used any package disabler?

my phone is pure stock, only thing I did was shut of aod in the settings.

for anyone just joining 25% battery lose as we sleep with airplane mode on and aod off. battery usage shows less than 5% as in the screenshot
[Samsung Galaxy Note 8 Real Life Review] harveydent:
Went to sleep with the phone at 100% with wifi and Bluetooth still connected (Gear S2). Woke up 7 hours later and the phone was at 98%
[Samsung Galaxy Note 8 Real Life Review] helasm:
I have the best battery time ever on a phone.
[Samsung Galaxy Note 8 Real Life Review] behemot24:
I didn't disable anything either, I just installed a few apps that I use frequently.

I'm doing a hard reset right now and if this doesn't solve the problem then I'll send back the phone too. At this price it should definitely be more stable: it's not normal to pay 1000$ and rely on luck to have a decent battery :rolleyes:
[Samsung Galaxy Note 8 Real Life Review] purchasedPhone:
Please let me know if the reset works for you. Did your phone ship with any carrier software? I'm considering flashing the "unlocked" firmware with Odin...

I will give it one or two more chances, tonight if it goes bad I'm calling Samsung
[Samsung Galaxy Note 8 Real Life Review] behemot24:
Mine is already unbranded so there must be another problem than the carrier software... I just made a factory reset, charged the battery to 100%, installed whatsapp and disabled a few apps and the 2nd SIM and stopped the wifi and data connection. Now I'll send it to sleep (I hope it listens!) and I'll post a battery usage screenshot tomorrow morning :fingers-crossed:
[Samsung Galaxy Note 8 Real Life Review] purchasedPhone:
you left cellular on but without the data? thanks and good luck
[Samsung Galaxy Note 8 Real Life Review] behemot24:
Yes, exactly... and still the same result: 75% after 7 hours. I will try the airplane mode tonight before going to samsung on Saturday. I can't think of anything else but that it's a series with battery hardware issue... it wouldn't be a first for them :(
[Samsung Galaxy Note 8 Real Life Review] MACHEK:
Yeah a guy in the poor battery thread said he had it checked by Samsung and his phone had a faulty battery. Think you'll get a new phone now :)
[Samsung Galaxy Note 8 Real Life Review] purchasedPhone:

[Samsung Galaxy Note 8 Real Life Review] yiyi28:
I have been using the phone for a week. The standby drain for overnight (for me from 00:30 AM to 9:00 AM, around 8hrs to 9hrs) is growing from 4% to 7% as I install more apps. I got constant 5% overnight until yesterday. Yesterday I installed Slack and some other apps, which caused it to drain 7% overnight. I think 5% is pretty good and 7% is below my expectation. I would see how things go in next few days. I leave everything on (Wifi, Bluetooth, Location) apart from AOD, and I have an LG watch connect to it all the time. I don't put anything in 'Always Sleeping Apps' and don't perform 'Device maintenance' at any time. I will try using 'Device maintenance' before I go to bed.
[Samsung Galaxy Note 8 Real Life Review] guaneet:
Only 1% lose overnight. Enabled Wi-Fi power saving mode only. I would usually have a 3-5% drain overnight
[Samsung Galaxy Note 8 Real Life Review] purchasedPhone:
here is a screenshot of my battery. I didn't put it in airplane mode this time, because, I won't usually be in airplane mode. I will test it again tonight with airplane mode, but I'm angry, a one thousand dollar phone shouldn't have a worse battery than my 4 year old iphone:confused:

---------- Post added at 05:21 PM ---------- Previous post was at 05:20 PM ----------

I think it's better if you just return the device and get a new one as it's in the return window.

[Samsung Galaxy Note 8 Real Life Review] purchasedPhone:
I ordered direct from Samsung and it took two and a half weeks to arrive.. I think the waiting line is just as bad at the moment. Will I still get my free wireless charger and sdcard? I helped justify the price with those items.
[Samsung Galaxy Note 8 Real Life Review] yiyi28:
The phone was officially launched last Friday, so I am not sure if you counted your waiting time during pre-order as shipping time? You need to find out the real shipping time from Samsung to you so you can better justify how long you would get it. Usually from Samsung website, it should not take two or three business days to arrive unless it says it won't ship in next few days. I think you need to contact Samsung for this especially in regarding the gift.

[Samsung Galaxy Note 8 Real Life Review] purchasedPhone:
Did you see my stats? I am currently charging it to full now so I can test again in airplane mode. This is so frustrating.
[Samsung Galaxy Note 8 Real Life Review] behemot24:
Yes, I have just about the same stats as you. I think we were just out of luck to get bad batteries, but I keep in mind it's still better than to have one of the Note 7 faulty batteries :fingers-crossed: #fireworks :cowboy:

Tomorrow morning I go to the closest Samsung Service Center and I'll let you know how this will be handled.

I don't think they have any of those in the US :crying:

[Samsung Galaxy Note 8 Real Life Review] mrnovanova:
My phone sleeps like a baby. 4% drain overnight, connected to gear s3. My s8+ use to lose about 10% overnight by comparison. I know that most people are all about SOT but standby matters more to me.
[Samsung Galaxy Note 8 Real Life Review] yiyi28:
Mine is between 4% to 7% overnight (8 hrs) with AOD off. My wife's S8+ is actually better with only 2% loss overnight. It's not consistent tho.
[Samsung Galaxy Note 8 Real Life Review] behemot24:
Well, it wasn't handled at all... the so called "Samsung Repair Center" in Bern was completely useless - first of all it was not Samsung but a company having a contract with Samsung, and then all they knew/wanted to do was to flash the same firmware again. As for hardware tests and replacements they just send the phones to the Samsung Center in Zurich... So I will go there myself some day as I don't want to spend a few weeks waiting for them to send back the phone :rolleyes:
[Samsung Galaxy Note 8 Real Life Review] purchasedPhone:
That's how it is around here. Nearest place is two hours away, and they don't even repair the note 8 yet because they haven't received the training. Even if there was something wrong they would just mail it away anyway.

A few years ago I got to travel and visit family in Schweiz it is such a beautiful place, I can't wait until I get to go next.

Have your installed another battery app yet? I now use gsam, I really like how it shows the battery usuage. Accubattery is another stats app if you don't like that gsam. Mine seems to be performing better now.. not sure why, I wish I had been running gsam when it was performing so poorly. I hope it keeps up ?
[Samsung Galaxy Note 8 Real Life Review] behemot24:
I find it beautiful too, I only moved in Lausanne last year and I don't regret it at all :)

GSAM shows that Phone radio is the one sucking my battery during the night! After having done some googling it looks to me like it's quite an old bug, even some S6 devices have it...

Some say that disabling VoLTE calls solves the problem. We'll find out pretty soon if it's true...
[Samsung Galaxy Note 8 Real Life Review] MACHEK:
You shouldn't have to. I have it enabled and don't have that draining at all
[Samsung Galaxy Note 8 Real Life Review] behemot24:
They say it depends on the LTE provider and on the signal strength, so maybe all Note 8's would behave like mine if they had my sim card and if they were in the same spot. But I won't buy another one just to confirm this :)
[Samsung Galaxy Note 8 Real Life Review] Warnahly:
The preinstalled samsung email application does drain you battery very very much

so disable it and you will get better battery life :D

when used the phone first time

wanted to test how the battery compared to my s8+, got almost 2h 50 sot only and the phone is dead

viewed the stats and email was 38% even tho i did only setup the email but never used it or never used the app

after disabling it could get 4h 15m - 4h 40m sot
[Samsung Galaxy Note 8 Real Life Review] dhaugru:
Nice! I will play around. Thanks man!
[Samsung Galaxy Note 8 Real Life Review] :
So yeah, I'm noticing with AOD turned off my standby battery life has improved very noticeably. It's a neat feature but it's not with the 9% on average drain I've been getting.
[Samsung Galaxy Note 8 Real Life Review] toby913:
Looks like we have the same problem unplugged mine around 01.00am got up at 06.00am and puff around 20 percent just gone. Below are my stats. I want to mention that I have the same problem with the s8+ plus. Could it be a backup gone wrong ?

[Samsung Galaxy Note 8 Real Life Review] behemot24:
Well, for me the culprit was the VoLTE calls!

I disabled it yesterday (in settings/connections/mobile networks) and then I lost only 3% over the night instead of almost 30%!
[Samsung Galaxy Note 8 Real Life Review] toby913:
Okay gonna test this. Which is your provider if you don't mind telling me ?
[Samsung Galaxy Note 8 Real Life Review] behemot24:
No problem, it's Sunrise (Switzerland).
[Samsung Galaxy Note 8 Real Life Review] toby913:
Could be possible that the feature is not yet fully supported or developed by sunrise and that's why it causes battery drain. I use sunrise too.
[Samsung Galaxy Note 8 Real Life Review] behemot24:
It all makes sense now! :highfive:

They even suggest themselves to turn it off if we run into problems: https://www.sunrise.ch/en/residential/mobile/mobile-network/sunrise-volte.html

[Samsung Galaxy Note 8 Real Life Review] indie:
I checked mine the other day and in 8 hours or so I lost 5% overnight. I have Wifi, bluetooth on and AOD but I do enable do not disturb between that time.
[Samsung Galaxy Note 8 Real Life Review] yiyi28:
It has become more consistent recently. 4% every night (8 hrs). The second screenshot was captured a little after I turn on the screen. It has dropped from 84% to 83% when everything is woken from sleep.
[Samsung Galaxy Note 8 Real Life Review] toby913:
Standby drain got better over night. Had data turned off my wifi turns off as soon as the device is supposed to enter deep sleep. Lost 5% over night.

Somehow I m not convinced and believe this is a coincidence. :rolleyes:

Hmm...after a few days, I think standby of htis phone isn't that great. I can do a number of things and probably lengthen the phone's life...but....I prefer to have bixby waiting for me to call, brightness at 50% and the resolution of the screen maxed! It just looks so pretty lol. I used bk disabler to disable a few apps but I still find standby to be lacking. Doesn't last me the whole day...screen on times are about 3 to 5...depending on how I use it...

Ok, update....I usually turn off auto sync, but I only found out today that I had it on the whole time. Turning it off saw a noticeable difference in battery drain. Worth a look checking out your auto sync settings in Accounts.
[Samsung Galaxy Note 8 Real Life Review] les_garten:
I'm getting over 4 days now on mine. Started out a disappointment, but has progressively gotten better. I also turned off almost all access to the notification bar except what I wanted.

I have BT on, WiFi and Location off. I also only manually sync, except Calendars and contacts are auto.

I also ran it down to shutoff 3 x. It got better everytime I ran it down to shutoff.
[Samsung Galaxy Note 8 Real Life Review] :
1 - Resolution: balls to the wall full resolution

2 - SoT form that screenshot: 2 hours as of now, I included an updated screen shot in this reply

3 - Wifi: It's on while I'm home, off when I'm out of the house

4 - BT: Only on when I'm in my car. Commute time to and from work/school is around 20 min each way.

5 - NFV: Did you mean NFC? I never use it. It's always off.

6 - Mobile Data: It stays on. I never touch the setting. Switches to 4g when I turn off Wifi (when I'm not home).

7 - Location (accuracy setting): Battery saving unless I need to use Google Map navigation then I turn on High accuracy.

8 - Google assistant on/off: Off

9 - Bixby on/off: On but not voice wakeup. Only launches through the button.

10 - Screen brightness: When I'm home it stays at 40%, when I'm outside during the day it's at 100%, when I'm outside after sunset it stays at 20%.

11 - AOD on/off: I keep that ***** off, not worth the juice. I have a wristwatch.

12 - Google Device Manager (find my phone) on/off: I never use that.

Thanks mate that's some good info.

We'll you're really getting great standby times which allows the long battery life.

I think it's due to 2 main things - your location is set to battery saving and your AOD is off.

You also switch off Wifi when out which should save a lot of the infamous Android "travel" drain.
[Samsung Galaxy Note 8 Real Life Review] :
Yeah I don't know why folks don't turn that off when they get outside their house. I see making these simple, quick switches on my way out the door the same way as making sure I have my car's key fob, home keys and wallet, along with my phone, of course.

[Samsung Galaxy Note 8 Real Life Review] xnutral:
I've had the note 8 for 2 weeks now and i have the feeling the stand by time is pretty good. The phone i had before is an s7 edge which was not bad in that department. The note 8 is not getting more battery life with usage, but standby is better. I'm usually at 60-80% at the end of the day with light use and everything on (bluetooth, wifi, data, nfc, location precision, AOD, 2 sim cards). I do have a wireless charger in my car, so it's kind of hard to see.
[Samsung Galaxy Note 8 Real Life Review] EarlZ:
I have something like 1% now with my note 8 for standby drain this is with WIFI enabled.. I think its pretty high..
[Samsung Galaxy Note 8 Real Life Review] Monkey Chops:
I'm having really fast battery drain due to google play services. Done all the usual stuff (I think), but it still persists. Phone is 3 days old. 1.5 hours of standby = 16-20% of battery drained. I found that my main google account (I have 2 on the phone) was having the dreaded sync issue, so I fixed that, but the battery is still draining quickly.

I have an S8+ and it is set up identically and that does not have the same issue.
[Samsung Galaxy Note 8 Real Life Review] gtaadicto92:
I'm getting rather poor battery life on my note 8. I think it is related to Android system and Android OS wakelocks.

I get 4.5h SOT tops on 4g data, 40-50% brightness,AOD on and medium power saving.

On Wi-Fi, no power saving,40-50 brightness,AOD on, I get 5h30 SOT max.

Fg_fullcapnom is 3253 mAh and fg_cycle is 8.

Gsam shows that the phone is awake when the screen is turned off and apparently there are no rogue apps.

According to gsam in 1h30 of usage, the screen uses 45% of the battery,mobile radio 5% and apps use 50%.

Background battery usage is 12.8% for Android system,9% Android OS and the apps such as tapatalk, Samsung browser, Twitter don't have more than 4%.

Background cpu usage is 8.5 min for kernel (Android os) and 3.5 min for Google play services.

What can I do? Is my battery faulty? I see people doing 6+h of SOT and that's impossible for me

I get almost 5 days out of mine. Well past 4 days. I would get 5 if I didn't recharge at 15% or so.

All the settings as shown in this thread, plus NFC off, or on as needed, GPS off unless needed, WiFi off unless needed, always on screen off, no edge, and very important... only Calendars syncing. No mail sync, only on demand.
