BatteryDrainer is an android app aiming to drain the phone's battery as fast as possible.
Why? With this application we demonstrate the need for energy-efficient software and sustainable software engineering practices in battery-powered devices, like phones or tablets.
As of 2022, IT systems alone already consume 10% of global electricity and by 2030 it is estimated that, the Internet, data centers, telecommunication, and embedded devices will consume one third of the global energy demand. Renewable energy is only a half solution. To address the root causes we need green IT in order to sustainably reduce the energy need of data centers and cloud services worldwide [1].

Currently BatteryDrainer uses the following hardware features to drain the phone's batter:
- CPU - Threads doing expensive computations (SHA-512 hashes)
- GPU - Using OpenGL ES 2.0 to draw thousands of small rotating pyramids
- Camera - Using the CameraX API
- Hardware sensors - Utilizes all of the device's available sensors (accelerometer, gyroscope, proximity, etc.) using the highest possible sampling rate.
- Network - Repeatedly downloads a large file over the network (WiFi or Cellular network)
- GPS chip - Using precise location accuracy
