iPhone Battery Life Tip That Actually Works, Immediately

If you have "Facebook Messenger," delete it. You're welcome. Go back to what you were doing.

I did this, and my battery life immediately and dramatically improved.

As it turns out, Facebook Apps are battery eating monsters, even when you think you are not using them.

Honestly, you could go in to your iPhone Settings > General > Background App Refresh and turn off Messenger, but why bother? Once you turn off Background Refresh, you have nothing but a big hunk of disconnected bloatware sitting on your phone, taking up space.

And, guess what? If you are like most people, you'll never miss it. Go ahead and open the Facebook App. Look in the "Messages" section. Yep, it's all there and you can continue to receive, reply and create messages right there. As it should be. In one app.

Facebook wakes up &
runs every 10 seconds!

Speaking of the Facebook App, it's gnawing away at battery life too. Unless FB updates are mission critical, consider turning off Background App refresh for it as well.
