Frame drops and lags on iPhone 16 Pro Max after iOS 18.5 update

Please try a Forced Restart. It is tricky and can take a few tries.

• Press and quickly release the Volume Up Button
• Press and quickly release the Volume Down Button
• Press and hold the Side Button until you see the Apple Logo (Keep holding past the Power Off Slider, which can take up to 30 seconds)

open whatsapp and wechat also got this problem

Multitasking is a feature provided by WhatsApp and WeChat, Apple does not natively have a feature for that on iPhone. For what it’s worth, both those apps have been releasing many updates every week to fix more bugs. So you’re going to want to make sure those apps are updated to the latest update, then report the issue to them.

In which applications is your iPhone slow?
