The first method is a simple trick. Enable Airplane mode by swiping up from the bottom of your screen to reveal the Control Center
. Tap the airplane icon and ensure it turns white, which signifies that Airplane mode is now active. Open up your WhatsApp application and your contact will not know that you have in fact read his message.
Another method to achieve the same result is more reliable and accessible: Simply configure the settings of WhatsApp accordingly. Go to WhatsApp > Settings > Account > Privacy and disable the Read Receipts. Read More…
How to see when the other side has read your message
This one is pretty simple but effective as well. Take your finger and swipe a message from right to left. This will reveal the Message Info screen, which includes both the Read and the Delivered time.
Hiding your WhatsApp profile image
You can save a lot of internal storage by turning off the feature that makes WhatsApp save any and all attachments to your iPhone. Even the ones that you haven’t looked at. Simply go to WhatsApp > Settings > Chats and disable the toggle labeled Save Incoming Media. Read More…
Better privacy for group chats
Constant notifications can drive you insane during a work day and WhatsApp group chats are notorious for their heavy activity. If you are pretty sure that you need some quiet time and won’t rely on being notified, you can opt to mute a group chat for either 8 hours, 1 week or 1 full year. Tap the name of your group chat while you are in the conversation view and select Mute.
Changing your phone number while keeping all WhatsApp chats
While the iPhone is a particularly sturdy device, it is far from invulnerable to loss or accidental firmware restores without a proper backup. Make sure to keep a backup of your chats if they contain any kind of useful information. Go to WhatsApp > Chats > Chat Backup and tap Back Up Now to launch a backup straight away. Configure the automatic backup to ensure the best safety for your data.
Reducing mobile data usage
The very special messages you receive in WhatsApp chats deserve to be saved. You can either take a screenshot, which might be lost at some point in the future, or use the favorites feature for this purpose.
