Got a laptop plugged in 24/7? You could be ruining your battery life, so prepare to do the charger dance

There are few things more nerve-wracking than a dying battery. Ok, there are quite a few things more nerve-wracking than a dying battery, like getting chased by a bear or receiving a missed phone call from your bank. Still, those of you who like to keep your laptops plugged in all the time to avert such anxiety—and I count myself among you—are in for a nasty shock, as it might be the worst thing you could do for your battery life.

That's according to Kent Griffith, an assistant professor at the University of California, whose research on battery degradation has led him to the conclusion that leaving your laptop sitting at 100% charge for weeks or months at a time can leave you with potentially half of your initial capacity (via Gizmodo). As someone who's been in the habit for years myself, I have to say that tracks rather perfectly with my own battery life experiences. Gulp.

So what to do instead? Well, according to Griffith the optimal state for your battery is roughly between 20% and 80% charge, meaning that the best course of action would be to charge your laptop fully before letting it discharge throughout the rest of the day, plugging it back in again when you reach the magic 20% mark.

Terrible news for battery anxiety sufferers such as myself then, who reach for the charging cable at around 60% at best, and mostly leave it plugged in when possible to be extra sure.

To be fair, as a fan of high-powered gaming laptops I hardly expect my battery life to go much beyond a few hours, but it does make me wonder exactly how many laptop batteries I've ruined simply by connecting the charger and leaving it plugged in whenever I'm near a convenient plug socket.
