The Standby feature on the new models comes in handy for those iPhones that still run iOS 17. For the older models, SimpliWall is the best option to go for. If ‘DIY’ is what you prefer, you can try to hang the iPhone on the wall and use apps that display the weather, time, or calendar and photos as screensavers. You can also make or purchase a few stands and attach the gadget to the power supply so that its screen always remains activated.
