How to put your old iPhone to use after you bought the new iPhone XS

Whether it's last year's iPhone X or a digital antique, that once-cherished device can have an entirely new life. AppleInsider shows just how that phone could still be immensely useful.

Using an iPhone as a security camera



Okay, we probably wouldn't be responsible adults if we didn't mention that you can give your old iPhone to your kids or a charity. We definitely wouldn't be fiscally sensible if we failed to point out that you can get a little trade-in value on your old device. Now that's out of the way, though, here's how you can make that phone do a brand new job just for you.

Actually, make that many, many new jobs. Each of which is free, comes with a subscription you use elsewhere, or is extremely low cost.

This is a computer you've got here, this is a miracle of technology and the only difference between your old iPhone and your new is that one has a SIM card in it. There are limits: the older the phone, the harder it is to get software that runs on it. So you need to know both what iOS version an app needs and what the latest iOS is that you can run on your phone.

Phones back as far as the iPhone 6 can run the current iOS 12 but older ones can't. As a guide, the latest that the iPhone 5 can run is iOS 10.3.3, while the iPhone 4's ceiling is iOS 7.1.2. If you've still got an iPhone 3GS then it's running no better than iOS 6.1.6 and it might be troublesome to get software for it, but not impossible.

If you are used to shoving all your old iPhones into storage, though, try popping one in your window instead.

Using Presence as a security video camera in iPhone



Security camera



You can now buy extensive and expensive home security systems that will let you setup multiple cameras. Those cameras stream over the internet so wherever you are, you can check to see what they're seeing. Or if you go a little fancier, a little more upmarket, you can have audio as well as video.

You can have motion detection so that the camera switches on when someone comes to your door. Or you could just use your old iPhone.

It's not going to be feature-film video quality but for a security system —and for free —this is more than enough to give you some peace of mind while you're away. Presence is a free-to-try app one that you install on both your old iPhone and another device like your new iPhone or your Mac.

When they're both on and both logged into a Presence account, you've got a security system.

Presence is really the start of a security system. You can pay $2 to upgrade to a higher-quality video or $49.99 for an annual subscription to a service that offers longer recordings and storage. Presence: Video Security requires iOS 6.0 or later.

The company also sells motion sensors, smart plugs and entire security systems. You may well get tempted further into Presence's products, but the free app running on your old iPhone is a steal.

Just keep in mind that iPhone batteries don't last long even on new devices so your ancient one isn't going to hold a charge while you go off on a European tour. You need to run a Lightning cable to the mains.

That's true for anything where you want to be certain the iPhone stays on continuously, or at least for many hours, such as a baby monitor. Maybe it seems like your child doesn't ever sleep for many hours. Maybe you'd gladly trade places with him or her, but at least this way you won't risk waking them by going to check.

There are dozen or more baby monitor apps for iOS: this one, Baby Monitor 3G, also has an Apple TV app. It requires iOS 9.0 or later.

Change the channel



Naturally you never tire of watching your kids but if by some miracle you should ever want to switch away from them too, say, Netflix, you can.

You know you can do this now on your iPhone: you can do it exactly as well and in exactly the same way on your old iPhone too. Netflix, YouTube and at least most if not all broadcasters' streaming services will let you watch on your old iPhone.

At least, they will so long as you're on Wi-Fi. This is where an old iPhone without its SIM card is effectively an iPod touch. It's a video player and as long as you have it signed in to your Apple ID, everything but calls will work.

The film Arrival playing on Plex in iPhone



If you're going to be watching video, though, give Plex a try too. This is an app and a service that lets you stream just about any video on your Mac to any Apple device.

When you've accrued years of ripped DVDs and iTunes won't play the format they're in, Plex is a treat. Not only does it let you watch the videos in many places but it fetches metadata from the internet. So you may have forgotten ever ripping your old DVD of 20,000 Leagues Under the Sea but Plex will recognize it and display the poster.

If you're on the same Wi-Fi network as your Mac, Plex is free. To use it away from home, you can subscribe for extra features for $39.99 per year or buy a one-time upgrade to your iPhone's Plex app for $4.99. It requires iOS 9.3 or later.

Music



If a SIM-less iPhone is like an iPod touch, then it follows that you can load it up with music. Just plug it into iTunes on your Mac and select what albums and tracks you want to store on it.

Only, you can't remember the last time you had to make a selection like that because you're an Apple Music subscriber. Strictly speaking, you're paying for an Apple ID to be subscribed —and there's no reason you can't listen on your old iPhone as well as your new.

So plug it into the mains in your kitchen, your bedroom or your office and listen to music all day. It won't be as good as having a HomePod but at least it's better than with your current phone which stops playing music every time you get a spam call.

Alternatively, forget music and listen to podcasts instead, such as this one.

Read in bed



Leave your new iPhone charging wirelessly on its Qi pad by your desk and take your old phone with you to bed. Switch off notifications and relax with some reading.

You can of course go for books through Apple's Book store or Amazon's Kindle. Kindle now needs iOS 10 or later and so does Apple Books.

However, you can also read Apple News on your iPhone if you want to keep awake all night. Or maybe read some articles that you've been meaning to catch up on: both Pocket and Instapaper are excellent read-it-later services.




Pocket needs iOS 9.0 or later while both Instapaper and Apple News depend on iOS 10 or greater. All three are free but Instapaper and Pocket offer paid premium versions.

Speaking of bed



As much as we love and cherish our Apple Watches, their Nightstand feature is worthless. If we're going to have a clock by the bed, we want to be able to see it —not to have to lean over and tap.

True, you can tap the actual Watch or just anywhere near it as vibration is enough to make it light up its Nightstand time face. So you can blearily do it, you don't have to be precise.

Yet with a spare iPhone you can do much more. This doesn't have to be by your bed, either, it can be a clock on your desk.

The app Disappearing Bedtime Clock being used as a desk clock on iPhone



Wherever it is, apps such as Disappearing Bedtime Clock are more adaptable and more functional than Apple Watch Nightstand. There are countless clocks on the App Store but by default, this one shows you a digital time display and then fades gently out.

So far, that sounds exactly like Nightstand. However, you can wave your hand in front of the phone to revive it. Or you can just tell it to stay on all night and when that's too bright for you at 3am, you can swipe down to reduce the brightness.

Disappearing Bedtime Clock requires iOS 11 or later and costs $2.99 on the App Store.

Old hardware



We've talked about iPhones here but that's really because we're all looking for ways to justify spending money on the new iPhone XR, XS or especially XS Max. Everything applies equally to old iPads too.

Really it applies to everything. If you've got a new Apple TV, for instance, your old one works very nicely when you're traveling. So chuck that in your luggage instead of the desk drawer.

You could get some money for trading these all in and if you pick your moment well, you might even get a decent amount. Yet you've already invested a lot of cash in these devices and they are far from finished yet.

Get your money's worth and exploit the technology to bring new life and new purpose to your old iPhone.

Emergency calls still work, and this is good and bad



Even without service, and the SIM removed, an old iPhone can still be used to make a call to emergency responders. This is good, as any device with a charge can summon help in an emergency, but bad if you hand it to a child to use as an iPod touch.

So, if you do the latter, just watch the tot. Otherwise, you might get an unexpected visit from the fire department or the police.

Still want to trade?



Perhaps you have several used devices lying around and you'd like to free up some cash after all. With trade-in bonuses at buyback providers, such as BuyBackWorld and MyPhones Unlimited, you can get $20 more over the trade-in values quoted on each site. We've outlined how to take advantage of the special offers and get the most for your trade in our iPhone trade-in guide.
