Sorry, But You've Been Charging Your Phone Wrong Your Whole Life


Bet you were proud of yourself for remembering to charge your phone last night, weren't you?

While the rest of the shitmunchers on your packed train were awkwardly clutching their juddering books, you were harvesting the power of electricity! If only for a night and a day, you'd finally pulled your life together.

Well, we're here to tell you: no. Turns out, you've failed yet again. Because according to a company called Battery University (so you know they're legit), you're committing a cardinal sin.

Apparently, leaving a phone plugged in when it's fully charged (for example, overnight) is bad for your battery. It keeps it high-stress and high tension, and eventually wears it down.

"Li-ion does not need to be fully charged as is the case with lead acid, nor is it desirable to do so. In fact, it is better not to fully charge because a high voltage stresses the battery," according to Battery University.

The solution? Just charge your phone when you first get in, and make sure to check on it after an hour. Or don't bother. It's your life.
