[Samsung Galaxy Note 8 Questions and Answers] jirka607:
Well facebook is using 8% of battery so i dont think thats the problem really
[Samsung Galaxy Note 8 Questions and Answers] Raklik:
Try to pass through the thread and see if you maybe missed something. Not sure how you get the phone, if you also did some import or you freshly installed. Maybe you tried to clean your cache? Basically, pretty much what guys here they were saying. I had horrible battery but now.. last whole day without struggle, without fancy settings or dark themes. I guess if I will tweak more on that I can squeeze 1.5 days.. but that will affect my productivity.. so a full day works for me.
[Samsung Galaxy Note 8 Questions and Answers] jirka607:
I have it brand new from T Mobile.

I odin flashed for clean install and did reset through phone and recovery.

Now i did reset again and installed only essential apps.

So i will see how it will behave today.
[Samsung Galaxy Note 8 Questions and Answers] Raklik:
I avoided t-mobile version just because a areflash is required to activate the second SIM card. Doesn't make sense to me to pay same price as retail version which has already unlocked the second SIM.

As I already said, mine looks like fixed! After yesterday, the battery life estimation is 20h .:good:
[Samsung Galaxy Note 8 Questions and Answers] jirka607:
In my country T-Mobile only sells single sim version. And i got it for almost nothing during contract renewal.

And in open reatail they sell only dual sim version which i did not wanted.
[Samsung Galaxy Note 8 Questions and Answers] Raklik:
I'm also from CR. I guess you had a special account at T-Mobile since price list with monthly subscription is just 35 euros less. :confused:
[Samsung Galaxy Note 8 Questions and Answers] jirka607:
Well i have a friend at T Mobile so he somehow did it.

But the battery is killing me...i will try to contact samsung express service since its Czech distribution.
[Samsung Galaxy Note 8 Questions and Answers] meboy:
It can often show as Android System or OS

It may be Google services or not.. It's extremely hard to narrow down in some cases.

Just have to go through the usual process of elimination.

May I ask your settings I get 4 sot 7 and 8 is really awesome
[Samsung Galaxy Note 8 Questions and Answers] jirka607:
UPDATE GUYS!

I went to Samsung customer center and put there my Note 8 to warranty diagnose and guess what!

Faulty Battery Unit!!!!

They immediately swaped my Note 8 for a brand new one.....it wasnt dangerous failure it just did not have the capacity and some other stuff.

So if in doubt get your device diagnosed....
[Samsung Galaxy Note 8 Questions and Answers] butchieboy:
Under location I turn off wifi scanning and bluetooth scanning. Screen is at about 50%. Use Greenify..I think its working. And disable things with Adhell. I only have 1page and a half of apps.
[Samsung Galaxy Note 8 Questions and Answers] darkjedi:
I'm almost to 10 hours SOT from the other day, and am at 9 hours with 12% left right now. Half WiFi, half LTE.
[Samsung Galaxy Note 8 Questions and Answers] jcrompton:
What is Adhell??

Sorry.... Found it I spelled wrong when I first searched
[Samsung Galaxy Note 8 Questions and Answers] Raklik:
so maybe you can let us know how much SOT you will get now. And where exactly you went.. maybe you can PM me to not pollute the thread. Thanks!
[Samsung Galaxy Note 8 Questions and Answers] jirka607:
I will write here with new stats im now on first discharge...it was samsung center on IP Pavlova
[Samsung Galaxy Note 8 Questions and Answers] EP2008:
You mentioned that you use Twitter. Can you check the twitter battery stats and see if "stay awake" seems unusually high?

Twitter had a "stay awake" that was many hours and prevented my phone from sleeping - it was the "scribe" service it runs that appears to be the culprit. I disabled it with BK package disabler (the scribe service, not twitter itself) and now it only stays awake for a few minutes based on my usage.
[Samsung Galaxy Note 8 Questions and Answers] Raklik:
how many of you with good battery life have the bixby active and set with voice password unlocking option? It seems that, since I activated that.. the power is in a free fall! I lost 42% in 3 hours with 30 min SOT.
[Samsung Galaxy Note 8 Questions and Answers] purchasedPhone:
This is my battery drain just sitting on a table. I have aod off, does this look normal?!
[Samsung Galaxy Note 8 Questions and Answers] yiyi28:
I think you should try 1. turn on 4G, 2. disable AOD, 3. leave everything else the same, 4. remove apps from 'Always Sleeping Apps'

AOD drains a lot of battery on my phone (at least 1%/hr), so I turn it off. With it off I got around 5 hrs SOT in a 20 hrs~ish cycle. If I turn it on it lasts at most 3.5 to 4 hrs SOT in a daytime cycle (16~ hrs)
[Samsung Galaxy Note 8 Questions and Answers] Raklik:
do you have Bixby on?
[Samsung Galaxy Note 8 Questions and Answers] purchasedPhone:
I haven't used any package disabler but I haven't enabled Bixby in anyway. I already have aod off and I don't think 4g is on, sprint doesn't use it much and my town has a only has a micro spot with it anyway

[Samsung Galaxy Note 8 Questions and Answers] Raklik:
I'm wondering if this is not some random battery issue.. today was more than ever.. not making 10 hours, with 50 min SOT and 18 min. phone call.. that was pretty much all having same settings as yesterday. I'm starting to be really frustrated.
[Samsung Galaxy Note 8 Questions and Answers] purchasedPhone:
where can I find screen on time? my screenshot was with 0 minutes screen time, I'm just testing idle drain, which is aweful.
[Samsung Galaxy Note 8 Questions and Answers] yiyi28:
Not sure if it's on or not. I didn't install PDP so no service disabled on my phone (I disabled apps that I don't use and can be disabled by default like Att crap and FB) but I also didn't set it up, so if I press the Bixby button, it jumps up a window for me to click 'Next', which is the first step of setting it up. My guess is it's still running but it wouldn't consume as much battery as after you set it up.
[Samsung Galaxy Note 8 Questions and Answers] Raklik:
on the battery usage page the first in the list is Screen. If you tap on it you will see the SOT. I'mnot aware of a different method.

My current stats sucks.. I'm slowly start to reconsider having the note 8. :(
[Samsung Galaxy Note 8 Questions and Answers] vibrantliker:
Does this look normal? 15 hours = Note 8, 39 hours = S8+
[Samsung Galaxy Note 8 Questions and Answers] tolymatev:
One is in airplane mode, itll last a week in that mode. That's where the difference is. LTE/wifi connected device wont last very long.

Put them both in Airplane mode tomorrow after you unhook them from the charger, yhen show us the estimated stats
[Samsung Galaxy Note 8 Questions and Answers] vibrantliker:
I actually took it out of airplane mode and it was the same.
[Samsung Galaxy Note 8 Questions and Answers] Jammol:

You may have a defective battery, return it while it's under warranty and get a new one. For the money you spent you should not have to deal with this sh$t.
[Samsung Galaxy Note 8 Questions and Answers] jirka607:
It looks like even my second note is showing battery smptoms.....i will let them diagnose it just to be sure....if yes then goodbye samsung..
[Samsung Galaxy Note 8 Questions and Answers] Gary02468:
It's very unlikely that two phones in a row would have faulty batteries. Have you tried running in Safe Mode for a few hours? If that shows normal battery endurance, then it's got to be your apps that are causing the problem, not the battery.
[Samsung Galaxy Note 8 Questions and Answers] jirka607:
I have really tried everything
[Samsung Galaxy Note 8 Questions and Answers] Gary02468:
So you get abnormally high battery drain in Safe Mode too?
[Samsung Galaxy Note 8 Questions and Answers] jirka607:
Yes i now dont have anything on my phone and it still drains like hell
[Samsung Galaxy Note 8 Questions and Answers] Gary02468:
Unless there's something unusual about your phone or its setup, it's not necessary to cripple the phone's functions or make elaborate optimizations in order to have decent battery life. For comparison, here's what I'm getting (TMO Note8).

According to GSam Battery Monitor, I average about 20 hours of battery life, and more than 4 hours of screen-on time, per full charge, with 10.5 hours light doze, 1 hour deep doze, 35% deep sleep.

AOD on, WQHD+ res, auto-brightness; 4G, WiFi, BT, NFC, GPS always on; Bixby Voice off but Google Assistant on. Gear S3 connected via BT.

I use over 100 apps (including the usual social-media ones), all auto-restored via Smart Switch. I've never factory-reset or cleared the system cache. I have no third-party de-bloaters, optimizers, or package disablers, nor have I disabled any apps manually (those measures sometimes backfire and cause excessive drain). All my power/performance system settings are the defaults.
[Samsung Galaxy Note 8 Questions and Answers] nuclearrage:
Still in my first week here , but kinda close to what you get.

18-20 hrs off charger

5-7 hrs soy

Wifi,bt,fine location,power amp player for 2 hours,phone calls for 2 to 3 hours,XDA alot,checking email,texting and so on. Even Bixby voice enabled.

I wonder if I am just lucky or what. I did a factory reset because smart switch had screwed a few apps up. I use darker themes cause I like them, not so much to save battery. I log out facebook religiously because it has always been a pita,even use Samsung browser sometimes instead of facebook app. But everything else is full performance. This note 8 blows the doors off my s7e,note 7, note5 and s6 . Just feel bad for you guys that are getting crappy battery life,when I do nothing really special and get great life.
[Samsung Galaxy Note 8 Questions and Answers] Gary02468:
I've seen others complain about the FB app's power consumption, but mine only uses 0.05% per hour. Maybe if I were more popular it would use more. :)
[Samsung Galaxy Note 8 Questions and Answers] Raklik:
I believe is software issue more than hardware. I had phone 100%, had 33 minutes voice call, hangup the call battery 85% let's say nothing weird here. From that moment I lost another 12% in a matter of minutes 20 max. just having it in stand by only. I realized what's going on and restarted the phone.. Since than I lost 3% in more than an hour while using the phone browsing and texting. I assume the calling app was still running in the background.

[Samsung Galaxy Note 8 Questions and Answers] tolymatev:
Here's my Note 8.

I removed it from the wireless charger when i went to bed. Lost 1% an hour.

Always on display was on all night. Wifi was on and woke up to a few notifications (a couple emails, facebook, Zynga poker, whatsapp) that's pretty impressive for me.
[Samsung Galaxy Note 8 Questions and Answers] tolymatev:
Have been off the charger for 10+ hours
[Samsung Galaxy Note 8 Questions and Answers] tolymatev:
Which variant do you have? Mine is Verizon
[Samsung Galaxy Note 8 Questions and Answers] Raklik:
unlocked retail European version. I cannot understand what is going on, the differences are too big even in between those are satisfied by the battery performance. I see an average around here of 16 h with SOT at 4-5 hours and sometimes performance like your which blows my mind!! 36 hours.. I would say that you are not using the phone at all.:D If I take your example as performance point means that all other devices are defective units.
[Samsung Galaxy Note 8 Questions and Answers] DaggettBeaver:
I strongly recommend a factory reset, regardless of the problems you're having. My problems weren't related to battery life. Various features simply didn't work after a Smart Switch restore. Factory reset and bypassing Google restore fixed everything. I'm getting great battery life, too. It's a pain re-installing all my apps, but it was worth it.
[Samsung Galaxy Note 8 Questions and Answers] themaximillian:
So you didn't use any form of restore?

Basically set the phone up "manually" and installed the apps one-by-one?

Skickat från min SM-N950F via Tapatalk
[Samsung Galaxy Note 8 Questions and Answers] DaggettBeaver:
Yup. After two restores that didn't work right, I figured it was worth the trouble.

I am surprised that Samsung's own SmartSwitch didn't work, but that may have been my fault for having it save and restore the system settings from my Note 4. I assumed it would be smart enough not to mess with the new things you could set in the Note 8, but I guess I was wrong.
[Samsung Galaxy Note 8 Questions and Answers] themaximillian:
Thanks for the feedback.

I resorted my Note 8 from my Samsung cloud this time after one reset ( orginally uses my backup from my S7E ) and granted, i did see a slight improvement but not as good as I've seen here. .

Gonna give it a couple more days and if it doesn't improve i'm gonna do it the hard way.

[Samsung Galaxy Note 8 Questions and Answers] WastedJoker:
I've been really impressed with battery performance especially standby performance.
[Samsung Galaxy Note 8 Questions and Answers] tolymatev:
Good point,

I always factory reset my brand new devices when i buy them. I never restore anything, always set it up as new device.
[Samsung Galaxy Note 8 Questions and Answers] speedtriple675:
Bought mine today. Did the smart switch at the store.

Came home charged 1 hour. This is where I'm at today, with moderate usage setting everything up. Once everything was set up I put most of the apps to sleep. That way only the ones I use daily are active.
[Samsung Galaxy Note 8 Questions and Answers] CalvinL:
I did a factory reset, did a smartswitch for my contacts, and then downloaded gsam. I'm getting 3.6% loss per hour. All I've done is unlock it and look at the screen a few times. I've been getting battery drain on idle like this from the beginning. Also, for some reason this phone won't let me update Bixby to the latest version. It says I already have it. Before I did a hard reset, it said I had an update but wouldn't let me actually update it.

I'm using the ATT Variant. Think I might return it to Costco and see if they replace it for me. I also have a Samsung center like an hour away.
[Samsung Galaxy Note 8 Questions and Answers] EarlZ:
Thats an awesome jump you are now getting 2hrs per 20% of battery life!
[Samsung Galaxy Note 8 Questions and Answers] Raklik:
difficult to say that is fixed. Sure, I have now 24h on battery, 3h SOT, 25% battery remained which calculated says 5 more hours. Problem is.. if I will get another long phone call.. would start to drain again? Do I need to restart the phone after each call?
[Samsung Galaxy Note 8 Questions and Answers] Gary02468:
If it's only phone calls that cause excessive battery drain, perhaps you're in a location of very weak transmission. What dBm signal strength do you have?
[Samsung Galaxy Note 8 Questions and Answers] Raklik:
good point, I will measure when I get home. The problem was the drain after the call.. which happened until I restarted... I will test more on that this days..
[Samsung Galaxy Note 8 Questions and Answers] herpi:
A am a identical copy of you! No reset, no clear cache. Samsung Switch pulled my Note 5 over and everything works great! GSAM gives me .5% till .7% loss during an eight hour night sleep. I even found out that leaving WIFI on during the night gives me less power drain in total.

Wifi on : radio 56% and Wifi 6% Wifi off: Radio 84% (and Wifi 0 of course)

All much better than my Note5.

Huib
[Samsung Galaxy Note 8 Questions and Answers] Raklik:
which makes me to believe that I have a defective unit. from 100% to 40% in 5 hours with airplane on and no AOD, SOT was 35 minutes!! I mean .. sure there is a drain somewhere.. The inconsistency is killing me! 2 days ago.. last 25 hours, yesterday I did not even receive a call..

2 weeks and I'm so tired of checking the battery level and make screenshots.. So disappointed!
[Samsung Galaxy Note 8 Questions and Answers] jirka607:
Dobt worry they just diagnosed my second note and now battery and screen burn in after 3 days.
[Samsung Galaxy Note 8 Questions and Answers] Raklik:
uhm.. like.. so you went there for test and now is not draining anymore..? 3 days lasts your battery..?? for real? That would be the absolute record of the current thread. :laugh:
[Samsung Galaxy Note 8 Questions and Answers] jirka607:
No i went there they diagnose it

Found faulty screen and faulty battery

Im getting refund on wednesday and buying iphone 8 plus on friday
[Samsung Galaxy Note 8 Questions and Answers] Raklik:
faulty screen?? how is that possible? Also second faulty battery again? Pff.. I wonder if are users from Europe with a good device.. :confused:
[Samsung Galaxy Note 8 Questions and Answers] jirka607:
Faulty screen...made burn in after 3 days of usage
[Samsung Galaxy Note 8 Questions and Answers] AndiF85:
This currently where I'm at with mine. Not the best but not the worst either. Using highest screen resolution, aod, Bluetooth off Wi-Fi on 4g network high accuracy location. Did a restore from my S8+ so I wouldn't have thought it would cause much of an issue seeing as they are very similar devices. Just about to factory reset and start from scratch and see if any improvement. Hopefully I can gain something as to not even get a day from my phone just sucks! My galaxy note 5 had the best battery life out of any phone I've ever owned Apple or Samsung. 2 days easy per charge. I would expect things to go forward not backwards...
[Samsung Galaxy Note 8 Questions and Answers] Torquemada288:
Ouch. That's pretty awful. I turned off AOD and have the resolution at FHD. But I have Wi-Fi, Bluetooth, 4G and GPS turned on and use a dark theme.

From what I've heard, you should avoid restoring from a previous handset.
[Samsung Galaxy Note 8 Questions and Answers] AndiF85:
Just backed up some photos and now factory resetting then going to start from scratch. Will touch base here tomorrow to advise if any improvement
[Samsung Galaxy Note 8 Questions and Answers] Torquemada288:
I found that my battery life has gotten better over the span of a week. It was never as bad as yours but once you start over, give it a while to improve.
[Samsung Galaxy Note 8 Questions and Answers] bonerp:
I just about get to the end of the day usually with 10% left with normal use. thats around 16 hours for me.

For those who buy the phone and state battery life in the first few days, please don't. Your battery will take a week or so to build its stamina, so first few days can be disregarded.

Also always clear cache from the recovery menu after set up. It helps a lot as an awful lot of stuff goes on during installation.

And for the record I've always restored from a back up and previous phone (Note FE in my case, S8+ before, Mate 9 before that...) and NEVER had a problem. Setting up a device app by app - no thanks! I have over 140 apps!!!

I remember a couple of years ago my battery suddenly started crashing. It was National Coaches app. An update caused sudden high battery drain so you need to learn how to find out where problems might arise from.

Might help someone ^
[Samsung Galaxy Note 8 Questions and Answers] GallardosEggrollShop:
I was having poor battery life after my first week of owning my ATT Note8. Installed AccuBattery and BatteryStats but couldn't really find the real cause of it. I decided to pull the trigger and install the Unlocked firmware not only in hopes of fixing battery life but to also debloat my phone. I've been using it for 2 days now and battery life has improved tremendously. Before I was getting 3.5 -4.5 (if I was lucky) SOT, standby time would be barely 9 hours. On both days I've managed to get 5.5 - 6 SOT with almost 15 hours of standby. I did not restore from a back up and I downloaded roughly 100 some apps including games. I still want to wait it out a week before am completely sure that my battery problem is resolved but fingers crossed.
[Samsung Galaxy Note 8 Questions and Answers] lima002:
If you use volt just disable it because I had battery drain with that
[Samsung Galaxy Note 8 Questions and Answers] jcrompton:
Have you found any downsides to using the unlocked firmware on AT&T? Does your volte and wifi calling work properly?
[Samsung Galaxy Note 8 Questions and Answers] GallardosEggrollShop:
Yup those are the two downsides. volte and WiFi Calling do not work. I know someone had some success with calling ATT and having the IMS registered. I may try that later but for now I can live without both. I much rather have the phone debloated. All the crap the ATT version had was annoying and took up so much space.
[Samsung Galaxy Note 8 Questions and Answers] jcrompton:
I know that with my S7 Edge the required files were part of the CSC flash and then all that was required was an IMEI that AT&T recognized as a device capable of volte or wifi calling and of their network

So I'm not sure what the other person did

Be curious to know more details
[Samsung Galaxy Note 8 Questions and Answers] AndiF85:
Ok so did a full factory reset and went through the tedious process of installing everything manually and getting all the settings back the way I like.

Definitely an improvement over yesterday and as stated above as things optimise and battery settles in I should see more improvement. Also did the cache wipe after everything was installed and setup. Screen brightness been 60% of the time at 50% and 40% maxed out in direct sun 100%. Screen resolution on Max and I've set everything to sleep automatically through battery optimisation. WiFi on 4g location high accuracy and Bluetooth off. Vibrate and sound feedback and spen also on even when inserted (as I use a galaxy tab/book full size spen). Been browsing on Chrome and Tapatalk a bit of light gaming some Facebook and note taking as well as minor camera use.

On another note I've noticed some apps look different now (e.g. SwiftKey). It's like as if they could only update so far thinking it was my s8+ still but with a clean install it's a different/newer version?

Thanks for the advice all. Will update again in a week to see if any improvements.
[Samsung Galaxy Note 8 Questions and Answers] CalvinL:
My battery life improved drastically after I factory reset it and downloaded bk disabler. I just disabled anything with ATT in it, bixby, and a very small amount of Samsung apps.
[Samsung Galaxy Note 8 Questions and Answers] Torquemada288:
A dark/black theme and turning off AOD will help extend battery life. I liked AOD but the drain wasn't worth the benefit.
[Samsung Galaxy Note 8 Questions and Answers] GallardosEggrollShop:
That's what I did initially which helped a great deal but those apps/ATT bloat took up a significant amount of space as well.

Yup, AOD always gave me problems with drain. May have been the theme I was using, but having it off gave me a lot better standby time. As for the system theme I'm using the High Contrast Black theme from the Samsung Theme Store. Been using it since my Note7 (RIP) lol
[Samsung Galaxy Note 8 Questions and Answers] :
Same with me. It wasn't going crazy with juice consumption but there was a noticeable difference in battery life after I turned off AOD. Now it's just "Sometimes On Display". I'll turn it on here and there but mostly it's off.
[Samsung Galaxy Note 8 Questions and Answers] mankvl:
Out of the box was happy with it... got like 3 hours SOT and the phone was at 60% or 70%... but I did factory reset in recovery before setting it up from the start again. Now had a full charge from 0 to 100 and battery life is terrible android system is first, adhell is not working so using blokada that might be draining the battery? How does those VPN adblockers work? Do I need to turn it on only when browsing or can I keep it on all time?

Just for FYI second day and battery is superb got close to 6 hours SOT.
