Set your phone's home screen background to solid black
Following the same logic as switching your phone to dark mode — setting the background image for your home screen to a solid black color will save your phone's battery life and improve the longevity of your device.
Phone's with OLED displays use less energy when displaying darker colors. The most power-hungry component of a phone is the display — so a decrease in the brightness of a bunch of pixels can go a long way.1
But what about the picture of my family?
Well, that's an excellent point. People do like their family — sometimes they like their family even more than they like prolonging their phone's battery life.
This makes sense on the lock screen — where you can see almost an entire image of a family. However, on the home screen, the background image is usually obscured by app icons. This makes for a bad viewing experience — and even makes it harder to make out app icons.
Luckily on modern phones you can have it both ways — setting a different image on your lock screen and your home screen.
