There’s a special annoyance that comes with picking up your phone after it’s been sitting idle for hours, only to find the battery has dropped significantly. While the screen may not be on, your Android phone is always doing something. But is it doing too much?

If you happen to be connected to Wi-Fi most of the time—and let’s be honest, most of us are—there’s one setting that could be enabling some unnecessary background battery usage. It’s called “Mobile Data Always Active,” and it’s enabled by default on most Android phones. However, you’ll need to access a hidden menu to disable it.

Why is “Mobile Data Always Active” enabled?

I probably don’t need to spend much time explaining what this setting does. As the name implies, it simply keeps mobile data active at all times. The bigger questions are, why is this a default setting, and why is it hidden behind a menu that most people don’t know about?

The feature is intended to essentially make it so you never notice when your phone switches between Wi-Fi and mobile data. Say you’re connected to Wi-Fi at home, and you leave, or it just drops for a bit, your phone can quickly switch over to mobile data without missing a beat. It’s the same concept as keeping an app running in the background so it opens immediately.

So, why is this a bad thing? Well, first and foremost, it’s not. For most people, this is a nicety that makes switching between internet networks perfectly seamless. However, using mobile data does require more power than Wi-Fi, so if you’re blanketed in rock-solid, stable Wi-Fi all day, every day, it could be worth disabling.
