I hate this scale, it says low battery and shuts off after just 3 months of sitting in the drawer. It infuriates me that there’s still a lot of energy in the battery, I can use that in remote controls with no issues

If there’s enough battery to say “low battery”, then there’s enough battery to show the measurements!

All of which is fixed by a voltage regulator

Except the cheap part. But likely not by much.

You can order 3000 3.3V low drop out (LDO) voltage regulators on LCSC for $25.50. That’s less than a penny each.

Doesn’t help when you need 3.3V and the batteries are now down to 2.5V they are not putting a boost converter in there.

Batteries have one advantage over over supplies: extremely low noise. Even an good LDO will bump up the noise floor, and a cheap lcsc part will do so too. Plus you’s want a reasonably low dropout and quiescent current, which also increases price. Maybe 10ct in volume is reasonable for such a part - and yes, that will absolutely eat the margin

Absolutely, My kitchen scale remains accurate and can use the same battery for years.

Eventually, the battery drops lower than the device needs. So no, none of which is fixed by a voltage regulator.

No, not voltage, current.

Which in this case means: you need a constant supply voltage
