S21 Ultra Battery life really bad compared to all the youtube video review

So I bought the new S21 Ultra on the pre order the day it was announced. I was one of the lucky ones to get early so I could leave a review. 

 

Coming from a Note 10+ that I had for a year and a half, I was really excited for the S21 Ultra, but was really disappointed with the battery life. I've had the phone for 5 days now and since the very beginning I've not been able to use the phone for the whole day on a single charge. It's been giving me screen on times comparable to my Note 10+ (4/5 hours) which is a much older device, but I thought maybe this was the way all S21 ultra's were behaving, just not very good battery life.

 

BUT, yesterday all the youtubers started to publish they're videos comparing batteries with older S devices and Iphones and their S21s were doing amazing, giving them screen on times of up to 13 hours! 

I contacted support but they said this would be normal as my phone was still learning user patterns... but I'm not sure if that would affect it as bad as it is at the moment. 

 

What do you guys think? Should I send the phone back? I'm really concerned that I just spent all this money on a new phone for it to be so bad with battery.

So after a while, it hasn't became better. Here's my SOT. 1h 29min with pretty regular use - some social media, a bit of camera and actually no games. Think it should have been a lot better

That's pretty bad considering from your graph that you even had charging during the usage period recorded...

They recommend you don't use smart switch because some of the apps are not compatible with the new software causing the apps to drain your battery quicker.

i've just re-installed my Ultra and will see if it improves things (No smartswitch this time). 
I'm just wondering regarding the learning that people are talking about. 
How does that actually work? Like others have said, iPhones just seem to cut it. My wife's nearly 2 year old basic iphone 11 has always around 65% left at the end of the day with similar screen time to me of around 2.5 ours whereas I've been going down to around 35%. Hoping this re-install will help. I have an Exynos Ultra 256GB

So I did the re-install without smartswitch about 2 weeks ago so given it time to learn as others have advised on.  This SOT is really poor and I didn't listen to spotify once today and PC addict for around 30 mins too so something weird there. Even taken that into consideration this is bad...
