A browser can't check these, so they aren't on the drawings
Battery wear. Browsers report charge level at most, not wear.
Drive health. A page can see its own storage allowance. We found no browser feature for drive health.
Heat and fans. We found no browser feature for temperature or fan speed. Some browsers offer a rough pressure level at most.
Fn and system keys. Fn is often handled in hardware, and a system can keep its own shortcuts, so a page may never see them.
Physical damage. Cracks, dents and water damage need your eyes.
How the report works
Each test on DeviceJig ends in a plain result. This page gathers those results, dated, on the drawing of each device. There is no overall score, because how much a sticky click matters against a dead pixel depends on you.
Passed: the test finished and its own limits were met.
Problem seen: the test found something. It suggests a fault and doesn't prove one.
Not tested: you skipped it, it didn't finish, or a warning means it needs running again.
Browser can't check: this browser can't give a fair reading.
A value a seller claimed appears only if you enter it, and it is labelled as yours. Results stay in this browser unless you press a share button. See the privacy page.
