The baseline videos are available underneath all the benchmarks. All devices are running Compressor **1.6.3**. > [!NOTE] > **Testing Context & Methodology (v1.6.3 vs v1.5.2):** > - **Thermal Conditions:** In the 1.5.2 benchmarks, devices were kept chilled in a cooler between runs. For 1.6.3, all tests were run at realistic **ambient room temperature (~21°C)** without active cooling to better reflect real-world use. > - **Timing:** Timing was captured manually via stopwatch, so a small margin of error is expected. > - **Comparison:** Comparisons against previous 1.5.2 results are included where the same device was re-tested.

*Why are the benchmarks different between versions?* Between v1.5.2 and v1.6.3, the testing methodology shifted from keeping phones in a cooler between rounds to realistic ambient room temperature testing (~21°C). Additionally, timing was recorded manually via stopwatch so minor variations are expected. Despite ambient thermal loads, optimizations across newer versions show substantial improvements on heavy workloads (such as 8K & 4K decoding on Exynos chips and budget devices like the A05s). *Why have some devices changed?* New devices (Galaxy Z Flip6, ZTE Blade A73 5G, Oppo A5 2020, Nokia 7 plus, and the Google Pixel 1st Gen) were introduced to provide a broader view spanning modern flagships, budget 5G/4G SoCs, and older legacy hardware. --- ## Credits Compressor wouldn't be possible without these amazing people [@rA9stuff](https://github.com/rA9stuff) - Inspiration to create Compressor & donated [@tgranz](https://github.com/tgranz) - Provided funding to get Compressor on Google Play [@sirtoaks](https://github.com/sirtoaks) - Provided funding to get Compressor on Google Play [@3r1s-s](https://github.com/3r1s-s) - Created Compressor's new logo [@AhmedRX20](https://github.com/AhmedRX20) - Translated into Arabic I would like to acknowledge that Compressor has used AI language models to assist in translation.
