Recently, we informed XPRT blog readers that after updating Apple iPhones and iPads
to iOS and iPadOS 17, respectively, we began to see WebXPRT 4 failures on those
devices. In the Safari and Google Chrome browsers, WebXPRT 4 test runs were
freezing while running the Encrypt Notes and OCR Scan workload. We were able to
replicate the issue on every iOS/iPadOS 17 device we tested, and we also confirmed
that WebXPRT 4 continues to run without issues on other non-iOS platforms.
Our team has been investigating the situation, and we’ve made some progress. It’s clear that the failed test runs are getting stuck when the WASM-based Tesseract.js Optical Character Recognition (OCR) engine attempts to scan a shopping receipt. During our research, we’ve discovered an issue when the current Tesseract.js engine runs on iOS 17. This issue is broader than WebXPRT 4, and the Tesseract team is aware of the problem. Future versions of iOS 17 or later versions of Tesseract.js may include fixes for the problem, but unfortunately, we don’t know whether or when a fix will be available.
investigating possible workarounds for the problem, and hope to be able to
start testing soon. Our goal is that any solution we implement will not
significantly affect existing WebXPRT 4 scores on non-iOS 17 platforms.
We will continue to share any substantive progress updates with readers here in the blog. Once again, we apologize for any inconvenience this issue causes for WebXPRT 4 users, and we appreciate your patience while we work toward a solution. If you have any questions or comments, please feel free to contact us!
At over 412,000 runs and counting, WebXPRT is our most popular benchmark. From the first release in 2013, it’s been popular with device manufacturers, developers, tech journalists, and consumers because it’s easy to run, it runs on almost anything with a web browser, and it evaluates device performance using the types of web-based tasks that people are likely to encounter on a daily basis.
With each new version of WebXPRT, we analyze browser development trends to make sure the test’s underlying web technologies and workload scenarios adequately reflect the ways people are using their browsers to work and play. BenchmarkXPRT Development Community members can play an important part in that process by sending us feedback on existing tests and suggestions for new workloads to include.
For example, when we released WebXPRT 3, we updated the photo workloads with new images and a deep learning task used for image classification. We also added an optical character recognition task in the Encrypt Notes and OCR scan workload, and combined part of the DNA Sequence Analysis scenario with a writing sample/spell check scenario to simulate online homework in an all-new Online Homework workload.
Consider for a moment what an ideal future version of WebXPRT would look like for you. Are there new web technologies or workload scenarios that you would like to see? Would you be interested in an associated battery life test? Should we include experimental tests? We’re interested in what you have to say, so please feel free to contact us with your thoughts or questions.
If you’re just now learning about WebXPRT, we offer several resources to help you better understand the benchmark and its range of uses. For a general overview of why WebXPRT matters, watch our video titled What is WebXPRT and why should I care?

We look forward to hearing from you!
