Its 1 month old so that it explains a lot..

But I thought Samsung said that the battery will only lose 5% of its power through 1 year?

I suggest you replace the battery then and try not to ignore that.

I will be replacing my battery too after 1 year.

---------- Post added at 05:59 PM ---------- Previous post was at 05:54 PM ----------

By the way its Inside warranty, Samsung should replace it for you for Free.

Thanks!

Will sendt it in ASAP
[Samsung Galaxy Note 8 Real Life Review] sefrcoko:
What settings do you have turned on? Brightness, gps, sync, aod, etc? How strong is your cell signal generally speaking? Might also be worth using Accubattery to get some stats and try to narrow down a possible cause on your side before sending it back to Samsung. That app also shows estimated battery capacity, which should help shed light on whether it's a software/configuration issue or a hardware issue (depending on whether it shows full capacity or something much lower).
[Samsung Galaxy Note 8 Real Life Review] stiffis:
Brightness on Auto, GPS on (when needed), sync is on, WiFi at most on, Bluetooth on and aod off.. I have always had it like this and got around 6Hr SOT when I first had the phone. It has just decreased over time to 3-4Hrs.. very dissapointed for a 1200$ phone..

I'm using Accubattery and BBS, do not see any "battery eaters" here..
[Samsung Galaxy Note 8 Real Life Review] stonedpsycho:
Phone on auto brightness and used a lot outside in the sun with 4g. Just hit 8 hrs SOT. About 4 hours of that is gmail though and at 31% battery. (14hrs off charge)

Suppose I average 7 hours.
[Samsung Galaxy Note 8 Real Life Review] stiffis:
Stock ROM?
[Samsung Galaxy Note 8 Real Life Review] stonedpsycho:
Yes.
[Samsung Galaxy Note 8 Real Life Review] sefrcoko:
4 hours of gmail will help that SOT for sure...not like 4 hours of gaming or Facebook, which would drain so much faster. Just another testament to how individual usage patterns have a huge impact on SOT, even with the exact same phone, settings, and apps installed.

My battery life started to suck. So i decided to flash Oreo

So far the battery is so great and the phone is smoother!I wonder why people are against oreo. It made my phone smoother and beautifull.
[Samsung Galaxy Note 8 Real Life Review] stiffis:
How much SOT are you getting? You can se how **** my SOT is..
[Samsung Galaxy Note 8 Real Life Review] Cool Person:
I think its about flashing the correct firmware.

Try to reflash your firmware.

I should note I am in medium power save mode (with background usage on) with hight brightness

Flashing this solved all my battery issues

N950USQS4CRE1

I remmember my battery life lately on noughat used to suck

I am quite confused what is going on. But I was begginning to think that my phone battery was dying.

P.S 4 Hours SOT AT 38% Battery
[Samsung Galaxy Note 8 Real Life Review] stiffis:
I have tried many times without any luck.. I have formatted the phone (all partitions) and reflashed it. Therefore I will send it in
[Samsung Galaxy Note 8 Real Life Review] Cool Person:
But you have 4 hours SOT? This is not bad at all.

Mine is at 80% brightness (I mean just below the warning level) though and medium power save and resault is 4 hours SOT at 38 percent.
[Samsung Galaxy Note 8 Real Life Review] stiffis:
It is bad.. When I first got the phone after release I got around 6h of SOT over two days.. and after a month or two it just slowly began to decrease to 3-4h over one day. It must be something wrong here.. :confused:

(You can see in this thread people are getting 6-9h SOT. That is what I want to get on a 1200$ phone too :) )

[Samsung Galaxy Note 8 Real Life Review] jayk_007:
People are boasting too much here. Been using Note 8 Exynos in India from October. I get 5 Hrs SOT in under 15H standby only if I'm indoors and using low brightness.

If I use my phone in outdoors quite a while and then keep my 4G always ON, it barely gives me 3.5hrs SOT in under 12H stanby. I don't do gaming. Whatsapl, Browsing with Samsung Internet, Some YouTube and some Facebook using the browser. Lol and people here are talking about 6 to 8h sot and over 25h standby??. It will only happen if you're using the device in low brightness and maybe low res.. No reviewer on Earth has got great battery on Note 8!
[Samsung Galaxy Note 8 Real Life Review] Msingh48:
I am from India & using note 8 Exynos version. Note 8 is giving realy good battery backup after june update. I am using medium power saving mode(speed limiter off) with auto brightness. AOD is on. If i'm indoors it gives 6 hrs plus and 5 hrs plus in outdoors. No standby battery drain bug now. One suggestion...clear cache after update.

14 hrs no savings settings. im good, and glad chargers are included for a reason until they make a solar powered cell phone.
[Samsung Galaxy Note 8 Real Life Review] stiffis:
It can vary from phone to phone and user to user..

Flash to the newest firmware CRF1 (with nand erase and repartition activated in ODIN), let it boot to "installing system update," let it finish and go to recovery afterwards and do a "factory reset" just to be sure. If you flash TWRP, wipe Data, cache and Dalvik cache. Internal storage is recommended too, but optional. :cool:

Remember to take backup first if needed!
[Samsung Galaxy Note 8 Real Life Review] Cool Person:
I have CRF1 And the battery is amazing.

I remmembered Noughat battery life started to suck for some reasons (I thought my battery was dying) but Oreo gave my phone back to life.

People with beta Oreo should install the latest version CRF1.
[Samsung Galaxy Note 8 Real Life Review] themaximillian:
I get fail when i try to flash using Nand erase and reparttion activated, what am i doing wrong?

Did you add the PIT-file?
[Samsung Galaxy Note 8 Real Life Review] themaximillian:
No i did not, where can i find the pit file?
[Samsung Galaxy Note 8 Real Life Review] stiffis:
In the CSC_OXM file. Use 7-zip to extract it :) Remember to reboot the phone after a fail..

Also, use the CSC_OXM in the CSC field, not HOME_CSC_OXM!

Its better for my eyes.

I can understand why some people don't like it thought.
[Samsung Galaxy Note 8 Real Life Review] michelino159:
That's my opinion. I like the colors especially in summer. Black is depressing, mourning. I never sacrificed anything to keep the battery one hour extra, especially software. I like to enjoy this superb display, otherwise what I bought to always see black. Who has problems with sight is ok. Inside is how it is outdoors, summer and with a pair of sunglasses I do not know how that black is seen in strong sunshine. Be happy with the phone! :)

Don't worry about standby thought lol

The Cell standby issue is because My SIM Card is outside the country I live in currently.

So its trying to get a signal.

I was just referring how my screen on time is great after 14 hours :cowboy:

My Battery is a double (Regularly I used to get from 4.30 to 5 now my phone would be 4 hours once it reaches 50%). Its just you have to sacrifice the white for black (to save amoled).

I don't mind since All I want is the text Information and videos (those work well with their regular colors).

Make sure you open the browser and chose Accessibility ---> High Contrast Mode too.

All of this really saves battery stress for me.

How has the CRF4 been? I'm a little too scared to update it. I don't want anything breaking or performance being affected.
[Samsung Galaxy Note 8 Real Life Review] michelino159:
Stay careless. It's the best Oreo rom ever before.

It's possible starting with security patch in July, Samsung is introducing a new U4 bootloader. Then you're having trouble.
[Samsung Galaxy Note 8 Real Life Review] Dchoi229:
What do you mean by having trouble? I'm actually not rooted. Keeping everything stock. I'll definitely update my phone.
[Samsung Galaxy Note 8 Real Life Review] sefrcoko:
Updated right away and no issues at all so far.
[Samsung Galaxy Note 8 Real Life Review] michelino159:
What I mean is you scared whether to do or not to update to CRF4? No I do not have root. I said to you that the next security patch update in July is possible to have a new U4 bootloader that I do not know how will it behave to the one we have now U3. There will be maybe a problem for all. U3 is excellent, for now.

How does the AccuBattery application look like to you? So much has gone from the battery in a few months of use?
[Samsung Galaxy Note 8 Real Life Review] sefrcoko:
I think Samsung said the battery will only lose 5% after 1 year of use. I don't know if Accubattery is accurate, but you can always try charging to 80% instead of 100% to reduce further wear on battery.

6 Hours SOT With 14 Hours of Usage. I squeezed about 2 hours+

Max Brightness FHD

but with Only Wifi because I don't have a data plan installed and my College has Wifi Connection any waysNo need to buy the Note 9 and if I even buy the Note 9 I will use this method too

This is with Dark YouTube , Samsung Internet browser (using High Contrast Mode which makes screen dark)
[Samsung Galaxy Note 8 Real Life Review] Cool Person:
Thats very good but I use Max brightness all the time (You use Auto brightness which dims the brightness according to light condition).

Its not a competition any ways.
[Samsung Galaxy Note 8 Real Life Review] michelino159:
It's not a competition, but I wanted to show that I enjoy and fantastic display with a very good use without black themes and no other black programs. ;)
[Samsung Galaxy Note 8 Real Life Review] Cool Person:
I use max brightness thought

your on auto thats the thing.

Battery would be 4 hours 30 Minutes without auto
[Samsung Galaxy Note 8 Real Life Review] michelino159:
On white, inside you can not keep it at a maximum, I have a minimum of 40% and outside 100% .While you can keep it as you want it is, it is also it.You are only wifi ,my and mobile data.With wifi they also reach 10h on the mobile at 5.6h. ;)

---------- Post added at 10:57 AM ---------- Previous post was at 10:50 AM ----------

In conclusion, the phone on the default with small settings is much better than if you apply some sort of unoptimized themes. ;)

---------- Post added at 11:06 AM ---------- Previous post was at 10:57 AM ----------

By the way, the automatic brightness is tested and recommended for the human eye.
[Samsung Galaxy Note 8 Real Life Review] sefrcoko:
Maybe, maybe not. We really can't draw that conclusion based on two phones with different usage though. Too many assumptions and variables to say with any level of confidence.
[Samsung Galaxy Note 8 Real Life Review] michelino159:
Anyway, there are other programs on black that do not bring a lot of autonomy because they themselves are energy-consuming. Besides, for what I gave 1000 €, to enjoy it, enjoy the screen, colors, of this wonderful experience. If I only have black in front of my eyes for an hour of extra autonomy and no other features like AOD, the discussion no longer makes sense. Enjoy the phones!!!
[Samsung Galaxy Note 8 Real Life Review] avatar_ro:
The real answer right here.
[Samsung Galaxy Note 8 Real Life Review] sefrcoko:
No, there is no "real" answer... Some prefer dark apps anyways (like me), so using them when possible will help with battery life. If you don't like them, then just don't use them and save battery in other ways. You can also disable any apps of settings you don't use, for example. No one is saying you should cripple the phone. It would be silly to disable things you actually use.

Honestly, I wish Samsung charged $900 for this phone, because for some reason once the price hits $1k everyone expects a "perfect" phone lol. Like that exists, regardless of price! ;)

When I installed Oreo I cleared the partition and then did a factory reset, plus set up the phone as new. No backups.

With every update/security patch I clear the cache for every app (laborious) and then the partition.

Settings wise I run my N8 in full performance mode but I have most apps set to sleep. I also switch notications off in apps that don't need them. I don't do much else! I may have forgotten something crucial and I'll have a think but so far as I'm aware that's it.

[Samsung Galaxy Note 8 Real Life Review] greatnorthgnome:
I am pretty happy with this thing. First four days I was averaging 5-1/2 hours of sot, which was still really good in my mind.

Mostly browsing internet, texts, and an hour of gaming.

Wiped cache, and apparently that was the ticket after the update I got on the first day cause I have 6.5 hours with 25% left to go.

Same usage basically. Aod, some advanced features turned off. Otherwise haven't really done anything.

I resisted and resisted moving to Oreo due to any potential battery life issues until one day accidentally pressing the download update button.

Glad to report it's no worse, maybe slightly better.

I usually charge before it drops below 50%.

Extrapolating the battery used percentage vs SOT, I should get around 6.5hrs on 3g and 8hrs plus if on WiFi.

I have a black theme, and only use data/Wi-Fi when needed.
