I'd avoid draining under 20% to keep the battery healthy.
Agreed. It is a known fact that you should keep the battery from draining too much. I left it to 15% today, and then recharged.
For info, using the older S10 charger USB-A to USB-C at fast charge 15 watts (1.67A *9V) it took around 1hr35 to charge from 15% to 100%.
This is not a super fast charger like the newer adaptors, but personally I don't see any point in upgrading my three Samsung chargers from previous generations of S8+ and S10+... they work fine, if only a bit slower.
In the first couple of days of owning the S21u I was a little worried about battery expectations, but I am now impressed with these numbers after the calibration and setting up is completed.

When I heard before release, that Samsung had clocked the global model's Exynos 2100 higher than the Snapdragon 888 devices, I was prepared to take a bit of a hit on battery life.
However, a week in to receiving the global Samsung Galaxy S21 Ultra I am impressed by 2 things...
#1 The battery life and SoT has greatly improved and matches my Galaxy S20 Ultra Exynos 990.
#2 How cool the Exynos 2100 runs, even when charging, (31C/88F), or doing benchmark tests.
Charging on the Samsung 25W charger and USB-C-to-C cable is 0% -100% in about an hour. Not far off the S20 Ultra on a 40W charger.
Battery life at 30 hours with 8h 34m SoT + juice left
One thing I noticed was that Sammy need to work on their Always on Display on this phone as it was using around 19% of battery until I took it off, "Show always", and selected, "Tap to show for 10 seconds".
[EDIT] I have just received an update for the Always on Display. Will see if it makes a difference.

I went to bed with around 24/25% with wifi on, I woke up with 20% left. First time I tried to push the battery up to 4% before charging it to 100% and I got 5hours and 55mins.
I know I shouldn't let it drain to below 15% but I just had to try. I feel like the SoT on my phone is quite disappointing compared to others on here.
