Has Your Computer Slowed Down? The Truth About Messaging Apps and Your PC’s Performance
Until recently, WhatsApp on Windows was celebrated for its efficiency. It was a lightweight application, often consuming less than 100 megabytes (MB) of RAM and delivering smooth performance even on older hardware. However, a significant shift occurred a few months ago when Meta, the parent company of WhatsApp, decided to discontinue this streamlined version and replace it with a new iteration. This change has had a profound impact, transforming WhatsApp into one of the most resource-intensive messaging platforms on Microsoft’s operating system, noticeably impeding the speed of even modern computers.
The Rise of “Web App Slop” on Desktops
The previous WhatsApp for Windows was built as a Universal Windows Platform (UWP) application. UWP apps are designed to be integrated seamlessly with the operating system, optimized for performance, and generally use fewer resources. Their efficiency meant a fluid user experience without taxing your system’s memory.
In stark contrast, the current WhatsApp for Windows is what’s known as a “web wrapper.” Instead of relying on a native, lightweight interface engine, it essentially opens an embedded WebView2 browser window within the application. While it might look like a regular app icon on your taskbar, internally, it functions much like an entire browser tab, complete with all its underlying processes and the significant RAM overhead that comes with it.
Understanding WebView2 and its Impact
WebView2 is Microsoft’s embedded browser control, powered by the Chromium rendering engine (the same engine used by Google Chrome and Microsoft Edge). When WhatsApp utilizes WebView2, it launches a full browser environment in the background, encompassing numerous processes responsible for:
- GPU rendering
- Network requests
- Sandboxing (for security)
- Audio processing
Each of these processes contributes significantly to the total memory footprint, adding dozens, and sometimes hundreds, of megabytes to your system’s overall RAM consumption. Effectively, Meta has pushed Windows users into adopting this new, resource-heavy version, which has become a textbook example of what the tech community critically labels “web app slop.”
Messaging Apps Shouldn’t Consume This Much RAM
For the average user, the problem with the new WhatsApp on Windows extends beyond mere statistics in Task Manager, although those numbers are quite alarming on their own. After simply logging in and engaging in a brief chat scrolling session, RAM usage for WhatsApp can surge to 1.2 gigabytes (GB). For prolonged use, there are numerous reports of it exceeding 2 GB on systems with less powerful configurations.
The issue becomes even more pronounced when you consider other applications running simultaneously—such as Microsoft Teams, which in its WebView2-based version can also consume around 1 GB of RAM even when idling. This scenario quickly leads to a system where just two communication applications can monopolize a substantial portion of a laptop’s typical 8 GB of total RAM.
To compound the problem, messaging applications are designed to run continuously in the background to ensure you receive messages and notifications promptly. This means that even when the WhatsApp window is minimized, its entire browser-based architecture remains active, continuously consuming valuable system resources. This constant background activity contributes to overall system slowdowns and reduced responsiveness.

A Path Towards “De-browserification” for Messaging Apps
Microsoft is actively acknowledging the issue of “web app slop” and has officially stated its commitment to moving away from this trend. The company is encouraging developers to build native applications using technologies like WinUI, Microsoft’s native UI platform for Windows. For major services like WhatsApp, this initiative presents a genuine opportunity to return to more efficient solutions that:
- Better integrate with the underlying system architecture.
- Leverage native Application Programming Interfaces (APIs).
- Avoid consuming gigabytes of memory simply to provide a straightforward text chat interface.
Despite this promising direction, the reality for the more than 1.5 billion active Windows users globally is that they are currently still compelled to use applications that are, in essence, “disguised browser tabs.” As WhatsApp continues to evolve with new features, including potential AI integrations and advanced storage management (learn more about WhatsApp’s massive update with new features, AI, and chat transfer), the need for a truly native, efficient desktop experience becomes even more critical.
Frequently Asked Questions (FAQ)
The new WhatsApp for Windows is built as a “web wrapper” that uses Microsoft’s WebView2 technology, which is based on the Chromium browser engine. This means the app essentially runs a full browser environment in the background, including processes for GPU, network, and audio, all of which consume significant amounts of RAM, often exceeding 1 GB.
“Web app slop” is a term used by the tech community to describe applications that are essentially web pages wrapped in a desktop shell, relying on embedded browser engines (like Chromium) rather than native system resources. While easier for developers to build across platforms, these apps often result in higher resource consumption (especially RAM) and poorer performance compared to truly native applications.
Yes, many other popular communication applications, including Microsoft Teams, also utilize WebView2 or similar web-based frameworks. This often leads to similar high RAM consumption, with some apps easily using 1 GB or more even when idle. When multiple such apps run simultaneously, they can collectively consume a large portion of a system’s available RAM.
Microsoft has publicly stated its intent to combat “web app slop” and is actively encouraging developers to build native Windows applications using its WinUI platform. This push aims to create more efficient, better-integrated software that leverages native system APIs and consumes fewer resources, ultimately improving user experience on Windows.
