Can you charge a modern smartphone wirelessly using only a stack of standard batteries? 🔋 We put this viral science "hack" to the test!
While this setup looks like a demonstration of electromagnetic induction (the principle behind wireless charging), the voltage and current output from these few AA/AAA batteries are far too low to power the phone's charging coil and internal circuitry.
The charging animation you see is often a visual trick or an edited effect, as this configuration is highly unlikely to provide a genuine charge to a modern smartphone! Science fact check complete!
