Use it when your phone is stolen.

Sent from iPhone 7

I keep mine around as a backup. So easy to flash your last backup onto it and use it between phones, if you lose or break your current one.

You could sell them for some extra cash. You can use them for music or as a back up phone

I use my 4s for verification codes whenever I get a new phone

Sell? Save one as a backup phone?

Whatever you do with them, don’t update them to the latest iOS version. They’re much more valuable with an older one.

I use my 6S to connect and play music on my car music system with aux since it doesn’t have Bluetooth or apple CarPlay.

I still use the SE as my whole phone sometimes. It's just such a good design.

The SE 2016 is the most able as a back up.

Maybe use the others as a separate media device, like as an iPod.

Sell them. All of these are worth at least 40 bucks.

You can turn them into security cameras. There’s an app called Alfred that allows you to set up the phones as security cameras and then the app on your phone you can view the streams. It works fairly well.

I use one for porn consumption. The other I use as a travel phone since the 15s don’t have SIM cards anymore.

My family has Go Bags for emergencies. We put old phones in them.

Call and text. Take photos and videos, use “clownshoe-ish” Snapchat filters, and stream your favorite tv shows & movies.

I use it as my camera for Zoom etc

Sell them

Configure some as iPod for childs

Keep one as emergency phone

My old devices, Android and Apple are useful for creating alternative accounts for some games. Currently, I have 18 devices with SimCity Buildit loaded. I got bored with that never ending game so most of those devices are just turned off. The old smart phone with just 16GB are still able to call 911, the emergency number is the USA. I was able to donate a few to the women’s shelter so the victims of domestic violence could call the police at least.

an iphone 5/5s/5c would do a good music player.

You could try eating them

I have a 3g that i kid you not, is as useful as my 2nd gen ipod touch even down to the OS except the 3g runs worse on 4.2.1

I’ve seen videos where you can set them up as security cameras

I have 5S 16GB, 5S 64GB and SE 32GB in my drawer. Soon 6S will join them, as i got new 13Mini to replace my 12Mini, that will go to my mother, that uses said 6S.

It kinda feels like waste, since all of them are in good condition (no cracked glass or big scratches to metal parts) and probably work as well (would have to check the 5S ones to confirm, but they worked fine, when we stopped using them.)

Third world country tip: always carry one so if you get mugged you give that one and they will believe it’s your main phone.

Also you can jailbreak one maybe? To play some old games that are not available on newests iOS?

You can purposely mess up government surveillance by tampering with their collected logs. First, log into two devices using the same iCloud account. Then, leave your old iPhone, with your registered SIM, at a different location. After that, connect your other device to WiFi. Messages from your iPhone will be forwarded to this other device, even though you're in a different location.

sell use as backup give to family friends if they aren’t bad

I usually sell them so I can recoup some money when I upgrade. I sell them in private.

I used a 3GS when I had a 5s as a landline phone (voip)

You could try jailbreaking them and play around with customization and theming.

Resell

You donate it to your neighborhood Witcher.

I use my 6s for Spotify because it has a headphone jack and the 6s DAC is not half bad at all.

You can resell them

iPhones retain their value much more compared to Androids

Any you wish to recycle should be handled responsibly. Apple Stores offer free recycling

My main iPhone is an iPhone 7. I do everything with it, it's fast without many hiccups and I can even do light photo edits with raw files. The real question is what can't you do?

My XR is my backup phone. My 7 was my backup until I bought my 15PM, once I had to use it. Just swapped the sim and went on my merry way.

I have one that I use as a dash cam.
