At first, I was disappointed by reading the note below from official WhatsApp FAQ:
Since your WhatsApp conversation history is not stored on our servers, we cannot retrieve any deleted messages for you. In WhatsApp version 2.10.1 and later, you can use our iCloud backup feature to back up and restore your chat history.
Tenorshare WhatsApp Recovery which enables us to extract WhatsApp chat history and contacts from iTunes backup file or from iPhone 5S/5C/5/4S/4/3GS directly, even supports iPad and iPod Touch. No tech skills are required, without jailbreak. For my part, much easier that iCloud! No time to waste, let’s get started.
Above all, downloading Tenorshare WhatsApp Recovery program on your computer and install it. Next I'll take a step-by-step approach to explain how to recover WhatsApp data from iPhone without jailbreak with two ways.
