Likewise, parking your old phone in a speaker cradle that also charges gives you a bookshelf sound system for music and podcasts. Or you can keep the phone connected to its charger and stream music to a nearby wireless Bluetooth speaker. Powered speaker docks can be found online starting at around $40, and a wide variety are available. Wirecutter, the product-testing and review site owned by The New York Times, has suggestions for Bluetooth speakers, general audio gear and those shopping on a budget.
And even if they have to stay tethered to a charger, old tablets also make good dedicated e-book readers or digital picture frames for photo slide shows.
Smart home appliances, music libraries, internet-connected televisions — so many things can be controlled by apps these days, so why not convert your old phone or tablet into an all-purpose universal remote? Third-party remote apps abound, but many tech companies (Amazon, Apple, Google, LG Electronics, Roku and Samsung, to name a few) have their own programs. Just take a stroll through your app store for software that matches up with your hardware.
And even if you haven’t lost the tiny stick remote that came with your set-top streamer yet, the onscreen keyboard included with most apps makes it easier to type in passwords. (Apple, which used to have a stand-alone Remote app, folded the Apple TV remote software into the operating system in iOS 12, but still has an iTunes Remote app for iPhone/iPad users to control their iTunes music collections stored on Macs and PCs.)
