ApexMark › Phone benchmark
Phone benchmark online
Test an Android phone, iPhone or tablet without installing an app. Open ApexMark in a mobile browser: available CPU, memory, graphics and internet tests run there, with unsupported capabilities reported clearly.
Run the benchmarkMade for phones as well as PCs
The CPU test uses the workers the browser can safely run. The GPU scene climbs the same resolution ladder when WebGPU is available; an unsupported or incomplete GPU test does not become a zero score. Mobile memory limits can also prevent a complete, comparable run.
Mobile tips
- Charge the phone, turn off battery saver and keep the screen on.
- Let a hot phone cool down between runs: heat throttles results.
- Use Chrome on Android and Safari on iPhone and iPad to start.
Frequently asked questions
Does it work on iPhone?
Yes, in a modern iPhone browser for the tests it supports. A GPU score requires WebGPU and a completed render and compute pass; availability depends on the iOS and browser versions.
Why is my second run slower?
Often heat or background activity. Phones may reduce performance as they warm up, so let the device cool and keep conditions similar between runs.
