Android 15: 16KB Memory Pages – A Performance Upgrade
2025-07-15
Android is transitioning to 16KB memory page sizes from the traditional 4KB, boosting performance on ARM CPUs. Starting November 1st, 2025, new apps and updates with native C/C++ code targeting Android 15+ must support 16KB pages. This change promises faster app launches (up to 30% for some), improved battery life, quicker camera starts, and speedier system boot times. Android Studio offers tools like APK Analyzer and alignment checks to help developers identify and fix compatibility issues. Developers need to recompile native code and avoid hardcoding 4KB page size assumptions. Emulator and certain devices support 16KB testing.
