A tech expert is urging people to avoid leaving their phones on charge overnight for a harrowing reason. It's no secret that smartphones have become essential companions, keeping us connected, informed, and entertained throughout the day.

However, a common habit that many smartphone users have adopted might actually carry unforeseen risks. Vincent lachetta Jr, president of Peppermonkey Media, warns leaving your phone on charge overnight could compromise both the longevity of the device and, potentially, your safety.

In a chilling warning, Vincent warns continuous charging after the battery reaches its maximum capacity can also lead to overheating. This could pose safety hazards, such as fire or explosion, in extreme cases.

However, most phones now have automatic protections against overcharging. Still, over the years we have seen several reports of phones exploding unexpectedly. This usually happens as a result of manufacturing faults, poor-quality hardware or physical damage.

Vincent also says that while charging your phone overnight may seem like a convenient way to ensure it's fully powered for the day ahead, the practice can lead to overcharging. He warns this is a phenomenon where the battery remains connected to a power source beyond its capacity, causing stress on the battery cells and potentially leading to degradation over time.

Vincent explains: "Overcharging your phone overnight can cause long-term damage to the battery, reducing its overall lifespan and performance." Leaving your phone plugged in overnight may also expose it to potential voltage fluctuations and power surges, which can further damage the battery and other internal components."

These risks are heightened when using third-party chargers or non-certified cables, Vincent says, as they may not regulate the charging process effectively. To mitigate the risks associated with overnight charging and ensure the longevity of your smartphone's battery, Vincent offers the following recommendations.

Unplug At 100%

Once your phone reaches 100% battery capacity, unplug it from the charger to prevent overcharging and minimise stress on the battery cells. Vincent explains: "Modern smartphones are equipped with advanced charging algorithms that can regulate the charging process, but prolonged exposure to a power source can still impact battery health."

Ditch Third-Party Chargers

Use only manufacturer-approved chargers and cables designed specifically for your device to ensure optimal charging efficiency and safety. Third-party chargers may not provide the necessary voltage and current regulation, increasing the risk of overcharging and overheating.

Keep It Cool

Charging your phone in environments with high temperatures, such as direct sunlight or near heating appliances, can accelerate battery degradation and increase the risk of overheating. Similarly, charging in extremely cold conditions can impair battery performance.

Deploy Airplane Mode

Vincent explains: "Activating aeroplane mode while charging your phone can minimise power consumption and reduce the risk of overheating. This mode disables wireless communication features, such as Wi-Fi and cellular data, allowing your device to charge more efficiently."

Just Avoid Overnight Charging Completely

Trickle charging can wear a battery down over time. That’s why many manufacturers have features to regulate it. Apple’s iPhones offer functionality to delay charging past 80%. Samsung’s Galaxy phones provide the option to cap the charge at 85%.

Instead of leaving your phone plugged in overnight, consider charging it during the day when you can monitor its progress and unplug it once fully charged. Overnight charging sessions can lead to prolonged exposure to heat, which accelerates battery degradation.

Vincent emphasises the importance of adopting responsible charging habits to preserve the health of your smartphone's battery and reduce the risk of potential safety hazards. He advises: "By being mindful of how we charge our devices and following best practices recommended by experts, we can prolong the lifespan of our smartphones and minimise the likelihood of battery-related issues.

"While charging your phone overnight may seem like a convenient solution, it's better to err on the side of caution and prioritise the long-term health and safety of your devices."
