Will erasing old iPhone affect my new one?

I recently upgraded to a new iPhone and set it up using iCloud. My old iPhone still has my data on it, and I’m thinking about erasing it to sell or give away. Will erasing the old iPhone delete anything or affect my new iPhone? I want to make sure my data and settings on the new phone stay safe.

Nah, erasing the old iPhone will NOT mess with your new one. Go ahead, hit that reset button with confidence! Just make sure your new phone is fully set up and backed up to iCloud or whatever you’re using. When you erase the old iPhone, it will only wipe that specific device. Like, imagine you throw away an old pair of sneakers, your new kicks aren’t suddenly gonna fall apart. Same concept. One thing to double-check, though: log out of iCloud on the old phone first, otherwise you’ll trigger the activation lock, and the next person won’t be able to use it. Save yourself the headache later!

Honestly, there’s no way erasing your old iPhone will touch your new one—these are separate devices linked to the same account, not some weird, interconnected hive-mind. @techchizkid is right that erasing only affects the specific device you’re wiping. Think of your iCloud as a storage room where all your stuff sits safely in boxes labeled with your name. Clearing out your old phone is like taking an empty box out and recycling it—it doesn’t magically delete everything from the storage room.

BUT, one trick people overlook: make sure iMessages and FaceTime on your new iPhone are completely signed in and functioning before erasing the old phone. Rarely, there’s a hiccup where the new phone doesn’t become the “main” device for things like iMessages if the old one was holding onto the settings first. You don’t want messages floating out into the void while you’re figuring this out.

Lastly, don’t forget Find My iPhone. If you erase it while still logged into iCloud, you’re gonna make it useless to whoever gets the device next. Trust me, nothing kills the vibe like handing over a bricked phone to a friend or buyer because you missed a step. Double-check everything’s off and signed out—better safe than cursing your past self later!

Alright, straight talk: erasing your old iPhone? Won’t touch the shiny new one. It’s not like some digital voodoo where deleting something on one device suddenly erases it elsewhere. Your data, as long as it’s properly synced and backed up to iCloud, stays safe within Apple’s cosmic cloud storage.

But here’s where I’ll toss in a new concern: Photos. If your photos are stored via iCloud Photos and you delete them from one device, they’ll disappear from all linked devices—not what you want when decluttering for a sale. To avoid this, turn off iCloud Photos on the old phone before erasing it, or double-check that the photos you want are downloaded to your new device.

As for the “Activation Lock” bit that others brought up (and good points from @sterrenkijker and @techchizkid)—I agree, that’s critical. But here’s a gem they didn’t highlight: not only should you log out of iCloud on the old device, you should also disable “Find My iPhone” altogether. This ensures the phone is truly yours to sell without hassles for the buyer. Pro tip: you can confirm this on Apple’s “Activation Lock Status” website.

Pros for your situation? Simple. Erasing the old iPhone helps you keep control of your personal data and prep the device for a new user. No need to stress about your iCloud account or data as long as the process is done right.

Cons? If you rush and skip steps, like not logging out or not confirming iMessages are working on the new phone, there’s a chance of minor inconveniences. Think of these steps less as “annoyances” and more as ensuring peace of mind.

Competitors, like Google’s backup for Android devices, work similarly but with arguably less tidiness than Apple’s ecosystem. While Android may offer more manual control, it’s not as seamless as Apple’s integration. The ‘’ makes managing your transition smoother, though it’s not 100% foolproof.

In conclusion: erase away, friend, but do your homework. Leave no data trace and enjoy that new-device glow without looking over your shoulder.
