Tech Tip: Battery Myths – Charging Your Phone Overnight

In this edition of Battery Myths, we’ll discuss what really happens when you plug your phone in overnight.

You may have heard that charging your phone overnight can cause your battery to “overload.” Basically – no. Your phone is smart enough to know when its battery is fully charged. However, you may experience an effect called “trickle-charging.” This simply means that your phone will expend some energy boosting the battery power whenever it falls to ninety-nine percent. This may affect your phone’s lifespan long-term, but ultimately it’s not really something to worry about.

It is important to make sure that your phone is in an open space if you’re going to charge it overnight. Trickle-charging creates some extra heat, and that’s not going to be good for your phone if you’re keeping it under a pile of blankets.
