While it runs
A countdown and progress bar, and a large estimated processor temperature over a heat map of your phone. You can stop a test at any time, and drag a finger across the screen to draw a snow trail while you wait.
Android stress test

Watch the heat.
YayoBench puts your Android phone under a heavy workload so you can see how fast it is and how warm it gets. Press Start to run a 30-second test in five stages, watch the estimated temperature as it runs, and get a score at the end.

THE 30-SECOND TEST
Five stages, one score
A standard test always runs the same stages in the same order, so you can compare results over time.
- 6 sSingle-core CPU
One processor core does math as fast as it can.
- 8 sMulti-core CPU
Every core works at once.
- 6 sMemory
Large blocks of RAM are copied and read back.
- 4 sStorage
A temporary file is written and read, then deleted.
- 6 s3D simulation
Thousands of particles and a 3D shape are moved and projected many times a second. This stage runs on the processor and is not drawn on screen.
WHAT YOU GET
Live readings and clear results
Your results
An overall score, a tier from "Entry / Efficiency" to "High-Performance", peak temperature and how much it rose, and stability: how steady multi-core speed stayed as the phone warmed up. You can share a result with other apps.
Max Temperature mode
Slide the temperature target on the home screen all the way to 50°C to switch to Max Temperature mode. Instead of the five-stage test, every core stays busy for the run length you choose, and the result shows whether your phone reached 50°C.
Hardware screen
Your phone's model, processor, core count, RAM, display, Android version and security patch, plus battery temperature, voltage, health and charging state. Cooling details and the heat-spot diagram come from a built-in profile for your phone's family and are estimates.
History
Each test is saved on your phone with its score, tier, stability and peak temperature, and your best score is shown at the top. You can turn history off or clear it in Settings.
Winter theme
The app starts with a winter look: snow effects and a snowman logo. You can turn it off in Settings.

SAFETY
Built-in limits
Stress testing uses a lot of battery and makes your phone warm. Don't run it while charging in a hot place, under a pillow, or in a case that traps heat.
- A safety notice appears before each test you start from the home screen
- A test stops on its own if the temperature reaches 44°C (52°C in Max Temperature mode), or if Android reports the battery is overheating
- After a heat stop, a cool-down of up to 2 minutes starts, and new tests wait until it ends
ABOUT THE TEMPERATURES
Android lets apps read the battery temperature, not the temperature of each chip. YayoBench shows the battery temperature and estimates the processor temperature from it. During a test, the temperature shown also follows an estimated heating curve, so treat the numbers as a guide, not a measurement.
