🔋⚖️ Storing #energy in a #battery increases the total energy of the system, which according to #physics, results in a proportional increase in mass.

For a standard #smartphone, this added weight is roughly equivalent to one-quadrillionth of a gram. The change is the result of energy being stored in the chemical bonds of the lithium-ion cells during the charging process.
