A recent WIRED article looks at a common habit many people have: leaving their phones charging overnight or for long periods. Reporter Dario D’Elia explains that improvements in power management integrated circuits (PMICs) in modern smartphones have made overnight charging much less harmful than it used to be.
The article focuses on a simple question: is it bad to leave your phone charging overnight?
According to D’Elia, the short answer is that it is generally safe with modern devices. Today’s smartphones are built with systems that stop charging once the battery reaches 100 percent. This helps reduce risks like overcharging and overheating.
That said, the article notes that while overnight charging is safe, it is not always ideal for long-term battery health.
In simple terms, phone batteries perform best when they stay between about 30 percent and 80 percent. Keeping a battery at full charge for long periods can slowly reduce its lifespan.
The article also highlights the impact of heat. Charging your phone under a pillow or blanket can trap heat and damage the battery over time. So, where you place your phone while charging matters just as much as how long it stays plugged in.
Another important point is to use proper chargers. Certified or original chargers help manage power safely, while low-quality or mismatched ones can increase risk.
Many phones now include features like optimized charging. These settings slow down charging overnight and finish charging closer to when you wake up, which helps reduce strain on the battery.
Overall, the article explains that overnight charging is mostly safe today. Still, simple habits like avoiding heat, using reliable chargers, and not keeping your battery at 100 percent all the time can help extend its life.
