Android 13 vs Android 15: What’s Changed and Which One Should You Choose
Android 13 launched in August 2022 and Android 15 in October 2024, with Android 14 in between. If your phone is on Android 13 and can move to Android 15, you gain two years of improvements in privacy, theft protection, multitasking, and accessibility. Keep in mind that Android 16 and Android 17 are now available too, so if your phone supports them, those are newer still.
What are the biggest new features in Android 15 compared to Android 13?
Several important features arrived in Android 14 and carry into Android 15, so moving from 13 to 15 brings both sets. From Android 14 you get lock screen clock and shortcut customization, font scaling up to 200%, flash notifications, regional preferences for units and the first day of the week, and passkey support through Credential Manager. Android 15 then adds Private Space, a locked and hideable area for sensitive apps, partial screen sharing that shares just one app and hides notifications and one-time passwords, saved app pairs for split screen on Pixels, and support for satellite messaging on compatible phones.
How do performance and battery life compare?
Android 15 includes stricter limits on background activity and on apps that start activities from the background, which can help battery life and responsiveness. It also enforces edge-to-edge layouts for apps that target it. Real-world results depend heavily on your phone and manufacturer tuning, and older phones may not feel faster. Expect a day or two of extra background work after a major update before battery life settles.
What privacy and security improvements does Android 15 bring over Android 13?
Android 14 introduced selected photo and video access, so apps can see only the items you pick, and it blocks installation of apps built for very old Android versions, which malware often uses. Android 15 adds Private Space and partial screen sharing, and Google rolled out theft protection features alongside it, such as Theft Detection Lock and Offline Device Lock. Together these make Android 15 meaningfully safer than Android 13, especially if your phone is lost or stolen.
Are there app compatibility changes?
Most apps that run on Android 13 also run on Android 15. Very old apps that target outdated Android versions may be blocked from installing, and some apps may look different until they adapt to edge-to-edge layouts. Google Play also requires apps to target recent Android versions, so long-term, newer Android versions get better app support.
How has the interface changed?
The core Material You design from Android 12 remains. Android 14 added lock screen customization and a monochrome theme on Pixels, and predictive back animations show where a back gesture will take you. Android 15 refines these and adds app pairs and better large-screen multitasking, including a taskbar on tablets and foldables that you can keep visible.
Which version should you choose?
If your phone can update beyond Android 13, do it. Android 13 is now well behind on features, and many phones on it are near the end of their security support. If your phone supports Android 16 or 17, those are better still. Stay on Android 13 only if your manufacturer offers nothing newer, and in that case check that you still receive security patches.
Conclusion
Android 15 adds a lot over Android 13: Private Space, partial screen sharing, theft protection, selected photo access, larger font scaling, passkeys, and lock screen customization. For most people, upgrading is clearly worth it, and newer versions offer even more.
