There are a number of things that can drain your phone’s battery life, even something as simple as browsing Tom’s Guide is going to cause that percentage bar to slowly creep down. But Android users may be interested to know that there’s a hidden setting deep in the depths of your phone that might be making the problem worse than it needs to be.
I’m specifically talking about the “Mobile Data Always Active” feature, which keeps your phone connected to cellular signals even if you’re connected to a stable Wi-Fi network. While there are benefits to this, the main drawback is that being connected to two types of internet drains your battery.
The good news is that it is possible to switch this feature off and help preserve a little bit of battery. The bad news is that it’s not easy to find, and you might need some help to get there. Thankfully, we know exactly where to go.

The pros and cons of Mobile Data Always Active
The name for this feature is pretty self-explanatory. The idea is that your phone will always stay connected to cellular data, regardless of what other networks may be available. That way, should your Wi-Fi or wired internet connection fail, you will jump straight back onto cell data without any meaningful delay.
While it’s not always perfectly seamless, and I always seem to drop WhatsApp calls if I stray too far from my home network, it is a genuinely useful feature to have. It keeps you connected and doing what you need to do, no matter the circumstances. Though it is one of those features that’s only useful when you need it, and actively hinders your phone at other times.
The major downside is that mobile data generally uses more battery than Wi-Fi, and keeping them running simultaneously is just a redundant waste of energy. Not to mention the fact that seamless transitioning between the two could lead to you using up more cell data than you planned, which is hardly ideal if you have a strict monthly allowance.
