Sometimes my phone's battery runs out outside.
If I turn off my phone before it runs out, will the battery not run out at all?
Turn it back on only when necessary.

Even if you don't use batteries at all, it doesn't wear out at all because it's a natural discharge.
But it's much less
It's called standby power, so even if you turn off your cell phone, it keeps getting power.
I use less if I take out the battery.
Then it's only natural, so I don't use batteries.
It'll take months to use up the natural discharge.
