While there are plenty of benchmark tests that PCMark offers to evaluate the battery life of a device, we at 91Mobiles test for a continuous video playback loop. This specific test isolates battery efficiency under moderate usage, simulating one of the most common real-world scenarios—video playback. It is especially relevant for students, travellers, and professionals who prioritize long-lasting battery life in their laptops. Including this test offers a practical measure of how a device performs on battery power during everyday tasks. Another reason why we at 91Mobiles opt for the video loop test is because it is inherently platform-agnostic. Since it focuses solely on video playback, it relies on hardware-accelerated decoding, which is well-supported across a variety of architectures like x86 and ARM. Unlike more complex productivity or workload-based tests, which may be influenced by platform-specific optimizations, the video playback test isolates battery efficiency without favouring one architecture over another. This makes it a more neutral and reliable measure of battery life for comparing devices with different processors.
