How to do it

  1. Turn on the charge limit in your phone's battery menu, if it has one. The name and location differ by manufacturer and model.
  2. Otherwise, look for the manufacturer's own charge-limiting feature.

Why it works

Heat makes lithium-ion batteries age faster, and charging to full raises the cell voltage.
