I press my iPhone’s hidden green button every week – it’s the only way to avoid ‘vampire’ battery disaster

DON’T let your iPhone’s battery life quietly drain in the background.

It’s easy to investigate what’s causing your “vampire” battery woes – and take action.

Go into your iPhone Settings app and look for the Battery section.

It’s easy to spot: it’s marked by a big green button with a white battery symbol on it.

Tap it and you’ll be able to see read-outs for how your battery is performing.

More importantly, you can check up on what’s draining your battery – and when.

You can choose between 24-hour and 10-day views.

This gives you an idea of what’s draining your battery today – and what might be putting the most strain on your battery more generally.

The really important information is below the bar chart.

You’ll be able to see batter usage by app.

This will reveal which apps are draining the most battery in percentage terms.

But if you tap the blue Show Activity button, you’ll get a new readout that reveals how much battery usage is occurring in the background.

Yes, some apps will drain your battery even if you’re not actively using them.

Apps like WhatsApp, Instagram, and Apple Mail might all be using battery in the background.

If an app that you don’t use often is draining significant amounts of battery in the background, that’s a bad sign.

Consider whether you can change settings on that app to stop it from happening.

And if you don’t really care about the app, maybe it’s time to just delete it for good.

It’s important to check the Battery page regularly, as app habits can change over time.

So even if an app doesn’t use much battery one week, an update or some other tweak may mean it starts gobbling up your charge later on.

If you notice you constantly have battery life problems, there’s a very good chance that a power-hungry app is to blame.
