WhatsApp Lagging on iOS 26? Here’s Why—and 5 Fixes That Actually Help

✅ TL;DR: You’re Not Imagining the Lag—But You Can Reduce It

After updating to iOS 26, many iPhone users are reporting:

• Lag when opening WhatsApp chats
• Delays in loading message threads
• Unresponsive keyboard or typing delays
• Notifications opening to blank or frozen screens
• General sluggishness in animations or app switching

These issues appear across various iPhone models, including the latest ones—not just older devices.

While not officially acknowledged as a “bug,” the behavior has been observed widely, especially among power users.

Let’s break down what’s going on, and how to fix it.

📉 What’s Happening?

🟥 1. WhatsApp chats take 1–2 seconds to open

Reddit users report a noticeable pause when tapping into a conversation:

“It just freezes for a second before loading. Annoying when you’re in a rush.”
— r/iOS user

This lag happens most often when switching between conversations or opening the app from cold start.

🟥 2. Keyboard is slow to appear or input is delayed

In several cases:

• The keyboard takes a second or two to load after tapping the text field
• Typing is delayed, making rapid replies frustrating
• The problem is more noticeable in group chats or long message threads

🟥 3. Tapping a notification doesn’t always work

Users report:

• Blank white screens when opening WhatsApp from a notification
• The app appears to launch but doesn’t load the conversation
• It only works properly if reopened from the home screen

🟥 4. After restarting the phone or closing WhatsApp, load times increase

This issue is particularly painful:

“After clearing it from RAM, reopening WhatsApp can take 30–40 seconds to load properly.”
— r/IndiaTech post

It suggests a caching or memory optimization issue in how WhatsApp interacts with iOS 26’s system-level changes.

⚙️ Why It’s Happening

This isn’t a one-app issue—it’s a combination of factors:
