Yes, really.

We’ve all experienced the pain in watching our iPhone battery drain before our eyes, scrambling around desperately to find a charger as the battery symbol turns red.

We’ve all tried switching our phones onto low battery mode and turning down the screen brightness in a desperate bid to retain some form of battery to keep us going, but wouldn't it be great if there was a fail-safe way to ensure that your iPhones could stay charged for the whole day?

Well it turns out there is and it's incredibly simple - the easiest way to save your battery life is to delete apps.

Even if we're not using them all the time, just having apps on our phones can eat away at battery life, and there's one that's particularly energy-sucking: Facebook.

That's right -'s mobile economist John Koetsier found that the background activity of his Facebook app alone used up a whopping 47% of his battery life, and by deleting it he could make his phone last twice as long without charge.

Whilst Facebook is the biggest culprit, there are plenty of other apps that are killing your battery, with Google Maps, Facebook Messenger, Instagram and WhatsApp following shortly behind.

There are of course ways that we can try to get around it: turning off location settings, turning off notifications and turning down the screen brightness, but the facts remain the same, just having the apps on your phone eats away at your battery.

It's just typical - of all the apps out there, from the Stocks and Shares one that we have never opened to the Health app that we ignore, why is it the apps that we're addicted to that are the most draining?
