WhatsApp for Windows, despite having a large user base of 3 billion globally and 1.6 billion on Windows, suffers from significant performance issues, including high RAM usage (400 MB before logging in and up to 1.2 GB while idling), slow message delivery, and a choppy scrolling experience. The app operates as a web wrapper using the WebView2 framework, which leads to inefficient resource consumption compared to native applications. Users across various hardware configurations report freezing, delayed messages, and instability. Microsoft’s Teams app also faces similar performance challenges due to its reliance on the same framework. There is a growing concern about the trend of developers opting for web applications over native ones, driven by a lack of trust in native frameworks. Despite Microsoft's push for native app development through WinUI, there is currently no native version of WhatsApp for Windows, while Meta has developed optimized versions for other platforms.
