I have a brand new s21 which eats battery power.

I have googled and applied all known fixes. 

If I charge pho e fully and leave it sit for 10 minutes locked, it's dropped to 99% when I open it. 15 minutes of browsing sees it drop to 94%.

Ive never had a phone with a battery this bad. Is this a fault?

Your phone uses more battery when it is new, give it a week to learn your usage habits and finish doing it's background setups.

That's normal the phone looses battery fast 100% to 90% and 10% to 0
It's best in between .
It's just the way it is.

Don't apply any fixed.
If it's a new phone let it learn your usage and keep everything adaptive or auto.

Samsung Internet drains a lot of battery. See, for just 37m it ate 7.3% of my battery! Samsung should really fix this otherwise I will use other browsers! (I hate Chrome)Screenshot_20211226-104723_Device care.jpg

I had the same issue with my S21 Ultra for the first week or two thaisken. My battery life was all over the place. It was all part of the phones early optimization as it gets use to your habits and settles in properly. It is all perfectly normal and mine settled in fine. My camera app got got too warm at first also and this took more time to settle down. Ten months down the line and my phone has brilliant battery life and a fantastic performing camera and runs cool and is blazingly fast. I couldn't be happier. I remember though how frustrated I felt with these early issues when I first used my phone though thaisken so I hope your issue resolves as quickly as possible and that my words provide some comfort to you. 👍

I am pleased to say that the battery has settled down on day 4.

It was draining so fast I thought it was faulty. It was taking up to 2 hours to charge from 70%.

But it seems like optimisation was indeed the problem and its working well. Thank you for your assistance.
