You know how it's a massive stress when your iPhone battery life is on single digits?
It turns out there's a genius hack (it's not actually that genius, you just need to be told about it) that will save you approximately 30 minutes of precious battery.
Just go into your phone's settings -> General -> Accessibility
There, turn on the option labelled "Greyscale." This will switch your phone’s colour scheme to black-and-white.
Why does it work? It takes less energy to illuminate a colourless iPhone display, so you’ll gain yourself some extra juice.
This will definitely help you in those desperate times.
