Proton VPN for Android – Platform Evaluation
Is Proton VPN good for Android? Does Proton VPN drain battery on Android phones? Proton VPN's Android application ranks among the most-downloaded privacy VPNs on Google Play. Testing was conducted on Android 12 and 13 across multiple devices to produce a data-backed assessment.
Proton VPN – Android
A polished, feature-rich Android application with WireGuard support, per-app split tunneling, and a permanently open-source codebase.
Android Features – Testing Notes
WireGuard Protocol
WireGuard is the default protocol on Android. Connection time was consistently under 2 seconds in tests. CPU usage under WireGuard is significantly lower than OpenVPN, resulting in measurably lower battery consumption over extended sessions.
Per-App Split Tunneling
Individual applications can be excluded from the VPN tunnel. Banking apps, local delivery services, or streaming apps that block VPN connections can be routed directly while other traffic remains protected.
Android Always-On VPN
The application integrates with Android's system-level Always-On VPN API. If the Proton VPN process terminates unexpectedly, the OS itself maintains the connection lock, preventing unprotected traffic from passing.
NetShield
DNS-level ad and tracker filtering is active system-wide on Android, including within applications – not only in the browser. Testing confirmed a measurable reduction in ad-network requests across the device.
Battery Impact
During an 8-hour continuous streaming session, battery consumption was measured at 7% above the no-VPN baseline. This is within the expected overhead for any active VPN protocol on mobile hardware.
F-Droid Distribution
The Android application is distributed via F-Droid in addition to Google Play. This provides an option for users who wish to avoid Google's Play Store infrastructure entirely.
Android Network Behavior – Extended Observations
Across extended testing on LTE and 5G networks, Proton VPN's Android client maintained consistent tunnel integrity during network transitions. Moving between Wi-Fi and cellular triggered automatic reconnection; in all test cases, the tunnel was re-established within 2 seconds. No traffic was observed passing outside the tunnel during these transitions when Always-On VPN was active.
One distinction from the Windows client: the Android version supports only per-application split tunneling, not address-based or subnet routing. Users who require subnet-level traffic control will need to rely on the Windows or Linux client for that functionality. The map view, while visually polished, performs less smoothly on older Android hardware – suggesting the interface is optimised for mid-range and flagship devices.
Strengths – Android
- WireGuard default – fast and battery-efficient in tests
- Per-app split tunneling confirmed functional
- Available on F-Droid (no Google Play dependency)
- System-level Always-On VPN integration verified
- Clean, intuitive interface
Limitations – Android
- Stealth protocol not available on older Android versions
- Map view occupies more screen space than ideal on smaller displays
- Auto-connect profiles offer limited configuration options
