iPhone 17 lagging while using insta, fb and WhatsApp .

My new iPhone 17 is lagging badly while watching Insta videos, Facebook page loading and videos, and l am also facing lag and call dropping while using what’s app video call. The home wifi connection is perfect as we use it on tv and other phones and there is no lag while watching videos on instagram, fb on them. I updated the phone to the latest IOS 26.3.1 and same issue. Just thinking of returning this phone but thought of checking about this first. Tried all reset networks settings, reinstalling apps, restarting modem and what not. Ewww ! Didn’t expect it from Apple

I thought of updating you regarding the issue. The problem is 5ghz vs 2.4 ghz network. I connected to my home internet 2.4ghz and all the apps are working fine without lagging video. Now when I switch to 5ghz wifi connection the problem comes back.

Those are all apps by Meta, the parent company of the apps causing issues. They’ve been struggling to fix bugs and optimize the performance of their apps for iOS 26.x.x

For example WhatsApp’s been updated 4 times in last week and 13 times in last month. Does that sound like a bug free and optimized app to you?

There several other threads in the community here discussing the same apps. It seems for every bug they fix, 2 more are released. They have no time to test their updates when releasing 4 apps in a week.

Apple Dawg, All the apps are working perfectly on my iPhone 16, Samsung S22ultra.

FYI

I am on call with apple support, we did speed test on all devices. IPhone 17 speed test failed. lol. Except all other devices.

That’s a test of your internet carrier speed and the particular service you subscribe to. speedofme is not known for its reliability or accuracy. Here take a look.

Ran the two test seconds apart. Speed test shows speeds nearly twice as fast. What speeds are you getting on your devices?

Your other devices use different modems and different firmware provided by your carrier.

Do you have any modem updates waiting to be installed?

iPhone > Settings > General > About > any notifications appear?

Do you use a VPN or ever had VPN software on your iPhone?

See what I’m referring to? The speed test numbers are much more accurate in my experience. That’s unlikely to be the real issue, but it could be. Does the lag occur on both WiFi and cellular connections?

Do you use a VPN?

I’m suspicious of your claims. Apple iPhone diagnostics does not have a speed test. It doesn’t exist. All the diagnostics return either a pass or fail for the various hardware components that can be remotely tested. I happen to know this for a fact as a former Apple Store Manager.

What country are you in?

I don’t use the VPN. Yes, it happens on home wifi and also when I try connecting my iPhone 17 to personal hotspot of my iPhone 16. In both cases it lags. Facebook, instagram and WhatsApp (video call).

if you see the speed is low and fluctuating while my other iPhone and Samsung have same consistent speed tests.

lThey asked me to do a speed test on speedof.me on all my devices. Now my appointment is with the apple technician today at Apple Store. You definitely need an update bud!
