How do I delete message from my iPad without deleting from my iPhone?

On your iPhone:

Settings > Messages > Text Message Forwarding - set to OFF

This will inhibit forwarding and synchronisation of Cellular SMS/MMS messages.

• Blue Bubbles = Apple iMessage
• Green Bubbles = SMS (Text) or MMS (Picture) messaging over Cellular messaging services

What is the difference between iMessage and SMS/MMS? - Apple Support

If you wish to inhibit all Messages on your iPad, you’ll have to sign-out from the Messages App:

Settings > Messages > Send & Receive > [AppleID] > Sign Out

Isn't this an iCloud issue...? Isn't the fact that messages are being duplicated on his iPad due to the way iCloud functions...? Aren't iMessages duplicated across devices the same way email is?

@gnomeattic, I think what you're wanting to do isn't possible because both your phone and iPad use the same iCloud ID and, so, due to the way iCloud functions (it's a syncing service, not a backup and storage service) your messages will duplicate. There's no way round this, it's how iCloud was designed to function.

The only way round this, is to use iMessage on one device only. If you don't want messages on your iPad, then you'll have to stop using iMessage on your iPad.

As messages are predominantly text, I shouldn't think deleting them would reclaim you much space, anyway.

Great - so you have now managed to sign-out from Messages. Once signed-out, any messages that are stored on your iPad are entirely local - and your should be able to delete them.

To delete messages from your message window, long-touch any message to expose an Action Menu; tap the More item - also marked with an ellipsis (“…”) icon - this will allow you to individually select each of the messages with a conversation that you wish to delete. When you’re done with marking the messages, tap the Delete button at the bottom of the screen.

Repeat as necessary for each message conversation.

As for Photos appearing on your iPad, you have evidently enabled Photos in iCloud on all devices - this being consistent with your Messages issue.

On your iPad, in settings, you simply need to disable all the iCloud services that you don’t wish to use:

Settings > [Your Name / AppleID] > iCloud - disable everything that you don’t wish to synchronise via iCloud with other devices.

Assuming that you’d like your received/sent messages to be replicated to iCloud and iPad and iPhone - but deletions from your iPad not synchronised with your iPhone…

On your iPhone:

Settings > Messages > Text Message Forwarding - set to ON - and explicitly enable your iPad from the list of devices

Settings > [Your Name / AppleID] > iCloud > Messages - set to ON

On your iPad:

Settings > [Your Name / AppleID] > iCloud > Messages - set to OFF

With these settings, messages that arrive will appear on both iPhone and iPad - but when deleted from iPad, the deletion will not be replicated to your iPhone.

I appreciate that you’re frustrated - but please understand that working through a problem is not necessarily straightforward. Either you have a strange issue that is not immediately obvious, or perhaps you are having difficulty with the instructions that I am making considerable effort to convey.

You should always be able to sign-out from Messages…:

Settings > Messages > Send & Receive > [AppleID] > Sign Out

Given the breadth of your difficulties, I cordially suggest that you make an appointment at the Genius Bar of your local Apple Store or Apple Authorised Service Provider.

Genius Bar Reservation and Apple Support Options - Apple

At the Genius Bar, the technicians will be delighted to work through your various difficulties with Messages, Photos and setup of your iCloud services. You’ll be able to demonstrate any difficulties that you may have - and leave with your i{ad and iPhone set-up to just the way that you want them to be.

No, email messages are not duplicated between devices using iCloud.

For email, each device will download mail messages directly from the email provider’s Mail servers.

Thank you for fixing my brain. 😀
