[Kross]

The batteries of our smartphones supply power for the smartphones to run. And it must be managed to give optimal performance.

Should the battery of smartphones be allowed to drain off completely? Does it cause any harm or is it beneficial if smartphone battery completely drains off regularly?

I can't really give the full details, but from what i have read, allowing your phone battery to always get to 0% is bad for your battery health.

Some quarters say that always charging your phone when battery is not completely drained would damage the battery.
