I've got a rpi 4 that keeps on randomly displaying the low voltage warning on its tiny little screen -- is it about to die?

As title implies. It's about to be 5 years old. Doesn't have a case. Runs 24/7 as a dns+adblock server, while (also) playing a live stream 24/7. systemd-journald is masked, and both cron/chrony removed. No stutter happens when the low voltage warning pops up tho.
Thanks in advance!
I would assume the power supply is just not good enough-or isn't good enough anymore. Rpis are notorious for needing high quality supply for current, preferably the official ones which actually provide 5.1V presumably to account for voltage drop on the cable.
Fair enough. Thank you for your input.
In addition to the above, if you have 4 or more USB devices connected to your Pi, that can also cause the power warnings. A powered USB hub should solve the issue, if that's the case.
To add to this. If you have more than one rpi, swap the power supplies and cables around in different combinations, see if the issue follows a particular part.
Electronics can get weird when they have voltage irregularities, you even see this as a hacking method on occasion, but it's not exactly consistent from what I understand. I saw an article where people started messing with voltage to a Tesla's CPU and managed to unlock premium features.
I am currently powering two rpi's with a 40w USB dual port charger, has been going well.
