Does Leaving Your Phone Plugged In Overnight Ruin the Battery?

Does charging your phone overnight actually ruin the battery? In this video, we dive deep into the hidden electrochemistry, power management chips, and thermal physics behind your nightly charging routine. From why modern battery management systems (BMS) make physical overcharging impossible to the real danger of electrolyte oxidation at 4.2 volts, discover why parking a phone at 100% capacity accelerates chemical wear. Learn how the Arrhenius equation proves heat is the true battery killer, why Apple and Samsung built 80% charging caps, and why charging under a pillow is far more dangerous than the plug itself. #TechExplained #BatteryHealth #SmartphoneBattery #HowItWorks #LithiumIon #TechTips #EngineeringExplained #OvernightCharging #BatteryLife #Stem
