Charging our phones overnight is a lot more harmful than we thought. It could actually shorten the lifespan of your phone instead of extending it or helping it. Most phones nowadays have a system in place that stops your phone from overcharging. Many smartphones do not stay at one hundred percent for too long.
Leaving your phone charging after it has hit 100% could impact your phone negatively. Business Insider’s Antonio Villas-Boas stated, “As a lithium-ion battery ages, the chemistry within changes and becomes less efficient at storing and delivering power to your device.” As batteries age and since we use our phones daily, their batteries begin to decay due to these reasons.
Phone companies don’t see overcharging your phone as an issue. Apple talks about their lithium-ion batteries in their iPhones, but has never really mentioned overcharging effects on its devices. Google claimed that overcharging is a dated issue. Since technologies are constantly updated, overcharging should not be an issue since their phone’s battery stops charging when it hits 100%.
Phone makers claim that phone’s battery should not be at 100% when you plan on not using them and store them away. If you plan on not using your phone for a while, it is recommended to store your phone away at 30% to 50% because that is when it ages the slowest. Samsung and Apple both stated to keep your phone around 50% for such purposes.
If you’ve been noticing your phone’s battery life deteriorating much quicker than its aging, it’s a good idea to set aside those overnight charges. Accumulated damage from such charges may cause shorter battery life span on a phone you plan to keep for a while. However, it does not matter how careful you are with your phone charger, it will deteriorate overtime regardless. Many phone makers now give you the option to replace your battery for a small price.
