I'm busy downloading 15.8.3 on my original SE right now. It's no longer my daily phone but when it was, it seemed to run perfectly fine in iOS 15. I should say, too, that I used to switch it off at night though as a matter of routine. I still love that little phone. I should have got Apple to replace the battery in it while it was still possible. Don’t fancy doing it myself.
I believe you can still get it changed at apple for $69I'm busy downloading 15.8.3 on my original SE right now.

Don’t do it. Battery life will definitely suffer as a result. I have 2 SEs running these two versions and there is a notable difference. I even think iOS 13 is pushing it but it’s much more tolerable than 15is it operating best at 13, or will 15 be a worthwhile upgrade?
If there’s no reason to upgrade then remain on iOS 13. If you need to have certain apps, such as Netflix which requires iOS 15, then you should upgrade.Don’t do it.

iOS 15 still get updates from time to time.So, besides security, which is already out of date after latest download, any big improvements over 13.1?
even with a new battery the performance will be impactedNo battery problem for me, just replace your old battery.
So far no impact for me.even with a new battery the performance will be impacted
