Wireless charging overnight is generally not bad for the battery. Modern smartphones have built-in safeguards to prevent overcharging. They automatically halt charging when the battery reaches 100%, even if left on the charger. However, constant overnight charging can keep the battery at full charge for prolonged periods, which may slightly reduce battery lifespan over time. To optimize battery health, aim to charge to around 80-90% and let it discharge before recharging.
