On the other hand, what about users that still haven't update their WhatsApp app version to the latest one (that has Background App Refresh capabilities built in)? I think they are still being notified of incoming WhatsApp messages even though their WhatsApp is running in the background without that Background App Refresh feature right?

I think someone posted in a prior post that having Background App Refresh enabled for the latest version of WhatsApp simply means when the user launches WhatsApp, there wouldn't be a delay, i.e. the "Connecting..." status when the user gets notified of an incoming WhatsApp mesaage & him launching the app itself to see the message. However, I'd Background App Refresh activated, for for my case, the "Connecting" delay still occurs when I launch WhatsApp to view a message that I was notified of.

That isn't Background App Refresh. The reason why your WhatsApp remain connected is because it was 'launched/opened' last 5 minutes ago.

Apple's multitasking policy allows an app (provided the app requires it) to stay connected for up to 5 (Can't remember. I think with BAR, this number is reduced) minutes before it gets 'cut' off.

So what's the difference in app behaviour for WhatsApp with & without its BAR capability activated?

Actually, I wasn't the one who stated this point; it's this fellow:

err I think apple explains it quite clearly.

err...I think that link, whilst informative, doesn't really specify whether WhatsApp will remain "connected" or only attempt to re-establish connection upon it bring re-launched. I think that link does suggest that without BAR, WhatsApp may use a polling model that is subjected to iOS's policy, i.e.
"Certain tasks or services can continue to run in the background. To lessen the affect on battery life, normal app background refreshing is scheduled for efficient times, such as when your device is connected to Wi-Fi, plugged into a power source, or being actively used."; with BAR, I think WhatsApp should be using a subscription model that will download new incoming messages the moment its servers receive them, i.e. "When Background App Refresh is on, apps that take advantage of this feature can refresh themselves in the background. For example, an app can check if new content is available and download the updates, or retrieve the updated content in the background when it receives a push notification, so the new content is ready for viewing when you launch the app.".

However, I'm curious, based on what you brought up previously:

do you mean for your case (I assume you have BAR activated for WhatsApp), every time you launch WhatsApp, you do not experience the "Connecting" delay?

After considering many sources I believe that BAR is smart enough to gauge when u are likely to check your whatsapp and pre-download the messages.

my understanding from e apple article is this:
I assume messaging apps to have this cycle when they r activated > connect > download messages. if they r switched to e background, e connection stays active for awhile (5mins?) before breaking n e app goes to sleep.

so for those apps with background app refresh, when they r switched to e background, instead of sleeping after e default time allowed to work in e ground, they repeat e cycle of activating > connecting > download messages > sleep based on certain patterns as mentioned in e article.

Updated, the lag seems to have disappeared (transitioning to main screen).
