S21 battery life

Had the new S21 for over a week now after switching from Huawei however I am finding the battery life dreadful.
I use my phone throughout the day on calls and watching videos. My Huawei would easily last a full day whereas I find I am having to charge my S21 at least twice a day sometimes more.
I have optimised all my settings and ensured everything was as it should be 

The main reason for drained battery seems to be Google chrome. It seems to be using well over 20% of the battery each time even when I'm barely on it .
Any suggestions on this one?

Maybe try putting it to deep sleep and see if that makes a difference?

Please use these tips from me:
First tip, always keep dark mode on if thats fine with you, secondly, go to settings, then go to connections, go to more connection settings and turn off nearby device scanning because it uses a lot of battery in the background, and the third tip is to uninstall any apps that you don't use because the less apps there are, the less battery that will be wasted in the background. Before I changed all these settings on my s20 plus, the battery would last about 6.5 hours but now I have changed the settings, the battery gives me about 9 to 10 hours before it dies which is a huge improvement. Please use these tips and you will have a much longer lasting phone and battery. Hope this helps!
Let me know if your battery lasts longer.

thanks I hadn't tried the scan nearby connection settings. its frustrating having to limit the functionality of your phone in order for it to last however.
I'll see if it helps any
it's Googlechrome that seems to be the main issue

My only issue with that is I have a lot of auto fill forms and other services with Google. Can I still use these in samsung browser?

I downloaded Google from the playstore and can still use auto fill forms with that.
