Android to gain performance boost with more RAM and 16 KB page size

Published

Google

Key Points:

  1. Android’s switch to a 16 KB page size offers a 5-10% performance boost but uses 9% more memory.
  2. Google is working to make Android adaptable to different page sizes, improving app launch times, power efficiency, and system boot time.
  3. Full support for the 16 KB page size is expected in future Android devices with more RAM.

Google is enhancing Android’s performance by supporting a 16 KB page size, a change that’s now undergoing broader testing. This update, focused on memory management, could significantly speed up Android devices.

Every CPU has a memory management unit (MMU) that translates program addresses to physical memory locations, and this translation occurs based on page size. When the page size is larger—like 16 KB instead of the traditional 4 KB—the system has to do less work, reducing overhead. This leaves more processing power for tasks like rendering videos, playing games, and running applications smoothly.

Historically, Android was designed to run on a 4 KB page size. However, Google has discovered that switching to a 16 KB page size can lead to an overall performance improvement of 5-10%, although this does increase memory usage by about 9%. Here are some specific benefits:

  • Faster App Launches: Under memory pressure, app launch times improved by an average of 3.16%, with some apps seeing up to a 30% boost.
  • Lower Power Consumption: During app launches, devices used 4.56% less power on average.
  • Quicker Camera Start: Hot starts were 4.48% faster on average, while cold starts improved by 6.60%.
  • Improved System Boot Time: Boot times saw a 1.5% improvement, saving approximately 0.8 seconds.

With the upcoming Android 15, Google has redesigned the operating system to be flexible with different page sizes, allowing it to function well whether the device uses a 4 KB or 16 KB page size. However, developers will need to recompile their apps to take full advantage of the 16 KB page size, although the same app can still run on both 4 KB and 16 KB devices.

Developers can start testing this feature with the Android 15 QPR1 Beta 1 on the Pixel 8 and 8 Pro. However, this “Boot with 16KB page size” option requires wiping the device and unlocking the bootloader, making it impractical for everyday use.

Google is collaborating with its SoC and OEM partners to extend this option to more devices soon and is also providing an x86_64 emulator for testing.

Although there are no Android devices currently in production or expected in the immediate future that support a 16 KB page size, Google anticipates that this change will align with the development of devices featuring larger amounts of RAM. As these devices emerge, the adoption of the 16 KB page size, and potentially even larger sizes, will become more common, leading to even greater performance improvements in Android devices.

Android 16 beta adds battery health info, Pixel Fold gets better at detecting opens and closes

Published

on

Android 16

Google has released the Android 16 Beta 1 update for Pixel phones, and it brings some helpful new features. One of the key additions is battery health information, which is now available in the settings. Pixel users can now see the battery’s manufacturing date, charge cycles, and overall health score. This can help people understand how well their battery is holding up over time. While this feature is currently hidden under developer options, it might be fully added in a future update.

At the same time, Google is also working to improve the Pixel Fold. With Android 16 Beta 1, there’s a new system that better detects when the phone is opened or closed. This new method uses the hinge angle to more accurately understand the device’s position. Unlike older systems that could be affected by software bugs or slow response times, this new one seems to be more reliable and faster.

These changes are important for people who use foldable phones like the Pixel Fold, as better hinge detection can lead to smoother app transitions and fewer bugs. And for all Pixel users, having detailed battery info can help with managing phone performance and deciding when it’s time for a battery replacement.

Overall, Android 16 Beta 1 focuses on giving users more control and smoother experiences, especially for those with foldables.

Android 16 could bring colorful always-on display to Pixel phones

Published

on

Android 16

Google is working on Android 16, and it looks like the update could bring more color to the always-on display (AOD) feature on Pixel phones. Right now, the AOD mostly shows white text on a black screen. But a new setting found in the Android 16 Developer Preview hints at the ability to add colors to this display.

The new feature is called “AOD Preview,” and it includes a switch labeled “Color AOD.” While this setting doesn’t work yet, it suggests that Google might be planning to show colorful content even when the screen is in low-power mode.

This change could make AOD look more lively, maybe by adding color to the clock, notifications, or wallpaper. So far, it’s not clear exactly what will change or how customizable it will be, but the feature seems to be in early testing.

Samsung already has more colorful AOD options on its Galaxy devices, so this update could help Pixel phones catch up. Google often introduces new features first on Pixel devices before making them available to other Android phones.

Android 16 is still being developed, and many features are not ready yet. But if Color AOD becomes part of the final release, Pixel users could get a more vibrant and useful always-on display in the near future.

Android adds quick shortcuts for do not disturb and video call effects

Published

on

Android 16

Google is testing two new shortcuts in Android that make it easier to control common features: Do Not Disturb mode and video call effects. These shortcuts are being added to the Android Quick Settings panel, which is the area you see when you swipe down from the top of your screen.

The first new toggle is for Do Not Disturb. Instead of opening the full settings menu, you’ll now be able to tap the shortcut to quickly switch between different DND modes. You can also long-press it to open full options. This makes it easier to silence notifications the way you want, especially if you have custom DND rules set up.

The second toggle is called “Video Effects”. This is useful for people who often use video calling apps like Zoom, Meet, or WhatsApp. When you tap it, it takes you to a page where you can turn on or off features like portrait blur, lighting adjustments, or filters that improve how you look during video calls.

These features are still being tested and might show up in future Android updates. Right now, some Pixel users with Android 14 QPR3 Beta 2.1 have seen these options. Google hasn’t confirmed when they’ll roll out to everyone, but they seem to be part of a plan to make Android tools more convenient.

In short, Google is trying to make it quicker and easier to manage your notifications and video call settings—all with just a swipe and a tap.
