You really don't want to go above 50% and certainly not to 100% for frequent or prolong times. AMOLED displays have a finite lifespan and what burns the brightest, burns the shortest.

Using it like that in direct sunlight is especially damaging, you can fry display drivers like that especially in high ambient temperatures. The active matrix screen has 10's of thousands microscopic solid state junctions not including the OLEDs... and very little heat sinking capacity.
The OLEDs and their driver matrix generate heat, the brighter it is, the higher the current draw and heat output.
Much of the heat sinking is through the display glass its self. Glass is a fairly good insulator, worse the sun's IR energy goes in and is trapped by the glass ie greenhouse effect.

It can go over temperature very rapidly before the device can thermal shutdown to protect its self especially if the device is already running hot or charging.
Yeah but under sunlight screen is barely visible except only when you set it to 100 % brightness and you know that.

So adaptive brightness is set ON,but anyway I need to increase the brightness outdoors maybe not 100 % but 90 % but what it makes the difference then?

I don't use my 10+ in direct sunlight, ever.
I only use manual brightness control, easier on the eye, the display and the battery.
At over 1.5 years my display shows no damage with ScreenTest.

People need to keep their eyes and attention on their surroundings when out and about, not their bloody phone. Bad things happen fast.
I don't have that bad habit... you'll live better and longer.

How much you keep brightness outdoors?
I didn't meant I keep phone in direct sunlight but at 50 % brightness you can't see nothing on screen outdoors.
I suppose need to set it to 80-90 %.

100% in seconds only and rarely.
If I need too around 70% again not for a long time. In general I refrain from outdoor use except occasional photos.

Exceptions are a unnaturally dark screen that the Samsung browser is infamous for when watching vids.
Probably about 99% of my SOT is at 50% or less.
I'm at around 32% right now, at night it drops lower. High levels aren't needed for sites like this. I run in dark mode whenever possible as well. I'll go to 50-60% for games sometimes depending on their ambience.

Using manual control makes you more aware of the levels you're using. Adjusting it now is instinctive for me. Eye fatigue is lower as well.
Auto brightness was always a mess... and a battery hog. One should at least have ability to set hysteresis and other variables. The one size fits all isn't cutting it🤣

So after 2 months of use(purchased used phone) ,my SOT is around 7h and 30 min with most of power savings ON (whatever I could do to presrve battery,including black theme,1080p resolution etc..)
Is it bad?

    I'm not able to go past the 4-5 hrs range but I do get a full day's usage..

    Seeing everyone's SOT I'm confused if there's a problem with my device or it's just some settings that can make such a huge difference.. :|

    keep in mind that most of SOT impressive results are achieved while web browsing or youtube watching.. etc, so no heavy gaming or 4k videos I suppose. Another crucial factor is the network signal, you get better battery life (both in screen on time and standby )when you've got a good reception and vice versa. In addition to the power mode of your device, the high-performance mode requires more power apparently.
    Rather than that, you should be on the same level of power consumption unless your Note has some hardware issue (Which I believe isn't the case).

    It's amazing how much we actually use our phones in a given day, especially when we watch "videos"! Rate this thread to express how many hours of screen-on time you can get on the Samsung Galaxy Note 10+ before depleting the battery.

    Then, drop a comment if you have anything to add!

    easy: you move to Huawei. Like I did, my note 10 plus was extremely unreliable.
    If you're so happy with Huawei, why are you still here spamming?.

    Did you ever really own a Note 10+?

    I'm impressed and that's just 3rd day after factory reset. Maybe 70% time on LTE

    Is it normal that my battery life seem to drain faster on LTE than WIFI? I got average on wifi 7-8 hrs of sot and lte i got 4-6 hrs
    Im on exynos
    It's absolutely normal, LTE always consume more juice from battery compared to WiFi (both with great signal reception). I hope/believe 5G after next 1-2 years, will change this fact
