Facebook!!!!
In a report by John Koetsier, a mobile economist, he discovered that by deleting the Facebook app you could almost double your phone’s battery life.
The discovery was made using an iPhone 7, which was bought in the hope of having a strong enough battery to last the entire day. However, much to John’s dismay, it was soon discovered that Facebook was in fact responsible for draining the majority of his battery.
The question is will Mark Zuckerberg, who is currently on a tour across America, fix the problem?
