Simple CPU Stress test tool for Android
About this app
This program is a simple stress test tool for Android devices.
It offers the following features:
- Forces the CPU to perform unnecessary calculations to generate load - Executes the process with a specified number of threads - Runs in the background, allowing work to continue even when the app is closed - Displays a solid black blank screen to prevent burn-in the display for devices that has OLED display - Also perform the memory stress test
How to use: On Android 13 and newer, When this app started at the first time, it will show a dialog requesting notification permission. This is required to the app can continue processing even when its window is not open.
In the "Threads:" input field, enter the number of threads to use.
In the "Duration (minute):" input field, enter the amount of time, in minutes, that the process should run. If a number is entered, the process will run for that many minutes. To run the process indefinitely, leave the field blank.
In the "Memory stress test (MiB:)" input field, enter a value in MiB if you want to perform a memory stress test. The test repeatedly allocates the specified amount of memory, writes arbitrary data to it, and then frees it, thereby stressing the memory.
Press "Start" to begin processing. Once started, a notification will appear indicating that background work is in progress. Press "Stop" to halt processing.
Press "Show blank screen" to display a solid black screen and temporarily stop the screen from sleeping. This is useful when running long stress tests on OLED displays.

Use cases:
- Battery refresh If the battery level is not displayed correctly, fully charging to 100% and then discharging to 0% can recalibrate the measurement. This app helps consume battery during that process.
- Warming the phone A device that has cooled down can suddenly shut down or freeze, making it unstable. Use this program in the winter to warm the device and stabilize its operation before it becomes unstable.
- Staying warm with the device Do you have a device with the CPU such as the Snapdragon 810? It's perfect for keeping warm! Use this app on the device and keep it in your pocket to warm your hands.

Installation Guide
Open Settings on your Android device
Go to Security → Unknown sources (or Install unknown apps)

Open the downloaded APK file from your Downloads folder
Tap "Install" and wait for installation to complete
Launch the app from your home screen
Make sure to re-enable Unknown Sources restrictions after installation for security.
How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be net.tlfoxhuman.droidstress is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 1.6.2 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall DroidStress first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of DroidStress, and a listing is removed when the evidence for it stops holding up.
