Earlier this month, we heard that updating to Android 14 improved the efficiency of the Google Pixel 7 and Pixel 6, increasing battery life and reducing heat generation. Now it seems that details of Android 14's efficiency gains have been revealed.

Android tipster Mishaal Rahman posted four of these improvements on X (formerly Twitter), noting that they are designed to improve both performance and memory efficiency. Optimizations include freezing cached applications, optimizing broadcasts, launching apps faster, and reducing the overall memory footprint.

Apps cached on the phone are frozen by Android 14 after a "short time". It is unclear how long this will take, but these apps can take zero CPU time. This allows the CPU to be used for other things, instead of consuming resources when the app is not doing anything.

According to Rahman, Google found that in the beta version of Android 14, cached processes "reduced CPU cycles by up to 50% compared to public Android 13 devices. This is quite good.

Android 14 also tweaked the way cached apps receive "context-registered broadcasts" so that they actually stay frozen. Broadcasts are queued and repetitions are merged into a single broadcast in the background.

These two optimizations have helped Google in reducing what is called cold app starts by limiting the maximum number of cached apps allowed. This means that apps are launched from scratch, which requires more CPU cycles; according to Rahman, beta testers have found that Android 14 reduces cold starts on devices with 8GB of RAM by 20% and on devices with 12GB of RAM by 30%. percent reduction.

Google also seems to have included optimizations that "reduce code size by an average of 9.3% without affecting performance. The smaller the code file, the better for both memory and storage, and the more efficient the process.

Google has not disclosed exactly what these changes are, and Lerman hopes the company will share full details about the changes in the near future.

Still, it is good to know that Google is working hard to optimize Android 14 anyway. Hopefully this trend will continue with future versions of the OS.
