Google details benefits of 64-bit-only Android phones, like more RAM, starting with Pixel 7 - 9to5Google

Google contiguous officially confirmed that the “Pixel 7 and Pixel 7 Pro are the archetypal Android phones to enactment lone 64-bit apps” and elaborate the benefits.

By dropping enactment for 32-bit codification and Android applications built that way, Google highlights respective tentpoles, starting with however 64-bit apps “run faster due to the fact that they person entree to other registers and instructions that aren’t disposable to 32-bit apps.” Newer CPUs run with 25% amended show “when moving 64-bit codification oregon even drop enactment for 32-bit code altogether.”

By removing 32-bit code, Android saves up to 150MB of RAM that “was utilized by the OS adjacent erstwhile not moving 32-bit apps.” This is credited arsenic resulting successful less inheritance app kills and “less jank.”

On the information front, address abstraction layout randomization (ASLR) becomes much effectual arsenic the countermeasure has much abstraction to enactment with to forestall representation corruption vulnerabilities.

Google touts entree to amended tools, similar HWASan for detecting representation errors, by conscionable targeting 64-bit. The institution has been moving toward this since 2014 erstwhile 64-bit enactment was archetypal introduced with Google Play requiring apps to enactment it from 2019 onward. The institution recommends that developers “start paying other attraction to testing their apps and updates for 64-bit-only devices” with Play, providing a prelaunch report for that scenario.

Lastly, “64-bit-only instrumentality configurations halve the CTS investigating time” for faster OEM updates. Google expects much Android devices to spell this route, but conscionable provides an “over time” timeline.

So far, some Pixel 7 users person deed the caller regulation erstwhile trying to instal older, nonupdated apps. There’s the Play Console app, for example, though Google wants Android devs to conscionable usage the website.

However, Google says it volition proceed 32-bit enactment for Android Go, Android TV, and Wear OS: “Please proceed supporting 32-bit ABIs; Google Play volition proceed serving 32-bit apps to 32-bit-only devices.” These signifier factors often usage older chips to conscionable much affordable terms ranges.
