Getting a new device and losing out on past conversations when you reinstall apps is frustrating. WhatsApp Messenger is arguably the most popular cross-platform messaging application on the planet. I honestly can't remember the last time I didn't see it in the top ten paid apps in the App Store.
Today WhatsApp Messenger for iOS received an update adding a few new features. iPhone users can send multiple photos in the same message, use custom URL-schemes for third-party apps, and back up conversation history to iCloud.
To back up a conversation to iCloud you'll first need to update to the latest version of WhatsApp, version 2.10.1.
After updating and letting WhatsApp go through its self-optimizing process, head over to the Settings section. Select "Chat Settings" and then "Chat Backup" toward the bottom of the list.
You'll have the ability to back up on demand, or set the app to automatically back up on a set schedule. Keep in mind if you have iCloud enabled to use cellular data, WhatsApp will use it to back up your conversations.
The next time you set up WhatsApp from a new device or a fresh install, you'll be prompted to restore your messages and photos. Videos aren't included in the backups.
