Every time you receive an iMessage, your iDevice saves a copy of the text/image/video. All iDevices are set to keep all iMessages forever by default, but that can lead to issues when a device hard drive runs out of storage space. Here is how to choose how long your device keeps iMessages.
- Settings
- Messages
- Keep Messages
- Choose the desired length of time to keep your iMessages.
- Note: All messages beyond the selected time frame will be deleted
