There are certain tasks we complete in life that don't require a second thought, like brushing our teeth, or clicking "Yes" when Netflix asks us if we're still watching Jane the Virgin. If, like us, you thought putting your phone on charge each night was one of those tasks, well… you're kinda wrong. Turns out, you can actually charge it incorrectly.
In fact, pretty much everything we thought was right about charging our smartphones is wrong, according to a report by the i100, informed by Battery University. These are the common battery-depleting mistakes that all of us make:
1. Charging to 100%
There are few things more satisfying than seeing "100%" in the top-right corner of your phone, but Battery University says that charging it all the way up is a damaging move. "Li-ion does not need to be fully charged, nor is it desirable to do so," they explain. "In fact, it is better not to fully charge, because a high voltage stresses the battery."
2. Leaving it plugged in when it's fully-charged
Similarly, it's a bad idea to leave your phone plugged in once charged—so, it looks like all of those overnight charges are a really bad idea. Once your phone hits 100%, it gets "trickle charges" to keep it topped up, which leaves the battery in a high-stress state, so it wears down quicker.
3. Keeping the case on
Sorry, guys. Sometimes you're going to have to remove that phone case with the glitter that swirls around, as cases insulate heat in your phone—leading to more battery drama. "If you notice that your device gets hot when you charge it, take it out of its case first," Battery University advises. You can pop it back on when it's semi-charged.
