+20 When your cellphone uses its vibration motor to warn you about low battery, it is ironically wasting even more of the battery you're supposed to save. amirite?

What? A single vibration uses such an insignificant amount of battery

The point is that if the effect is not true at all then OP should look for a better example.

But....it is true. Even if only by the slightest.

Alright well if your phone vibrating doesn't use power then what does it use?

Why is that ironic? In 99% of cases the user will have easy access to charging. Feature working as intended, and it can also be turned off....

It's ironic because it's using power to say it's low on it instead of conserving it. It's like if you were low on money so you buy a giant $10,000 sign that says I'm low on money. The example is an exaggeration of what's actually happening but that's why it's ironic.

I'm not sure about the numbers but a quick research says those vibration motors use around 25 ma current. A typical phone with 5000 mah battery would use less than 0.0002% of battery for a second of vibration. I think the advantage of you being warned about low battery definitely outweights the disadvantage of using some small energy.

Great, every day example of the Observer Effect - you can't observe a system without affecting it.

Batteries discharge over time. The vibration will go off regardless

Entropy! Yes! Physics lessons all over the place.

Not the same but I hate that my remotes will warn me for like 6 months that the batteries are low. Like I'm gonna use them until the batteries are dead ffs!

Right! A remote is not a critical piece of tech to function urgently. I'll replace the smoke detector battery immediately, but if one day the TV remote doesn't work I'm ok with that

Exactly vibrating takes more power than a simple sound or screen alert. It's a bit counterproductive when you're trying to conserve battery.

i think it is quite sensible.something like you are commander of an army that is losing a war and giving an order to leave some of your men behind to prevent more loss.

It actually is just "wasting" battery the whole time.
