Android is transitioning to a 16 KB page size, which will become mandatory for applications in the Google Play Store by November 1, 2025. This change replaces the previous 4 KB page size and aims to enhance performance by improving memory management and reducing overhead. The introduction of Android 15 has been refactored to support this larger page size, with testing currently available on Pixel 8 and Pixel 9 devices. Expected performance improvements include faster app launches (3% to 30% faster), improved battery usage (average gain of 4.5%), quicker camera starts (4.5% to 6.6% faster), and speedier system boot-ups (approximately 8% faster). Apps without native code should remain compatible, while those using libraries or SDKs with native code may need updates. Apps containing native code might require recompilation and review for compatibility. Developers can check memory page size support through the Play Console.
