8 Ways to Maximize Your Smartphone Battery’s Lifespan

Ovidiu Sandru — Tue, 18 Aug 2020 07:31:07 +0000

A lithium-ion battery naturally degrades over time and the number of years covered since its first use until the time it has to be replaced is called its lifespan or service life. The average lifespan of a lithium-ion battery is between 300 to 500 cycles. It discharges and recharges normally for the first 300 cycles, […]
