When choosing an Android VPN, check background reliability first, then battery use and per-app proxy routing. A connection that works with the screen on may fail after the phone locks; a connection icon in the notification shade is no substitute for testing access. A client suited to everyday use should make its connection status verifiable, system restrictions diagnosable, and app routing understandable.
Android VPN picks: distinguish the client from the route
Android proxy clients often use the system VpnService to create a virtual network interface and pass device traffic to a local proxy engine. A VPN icon in the system status area only indicates that the interface is enabled. It does not prove that a remote route is reachable or that a specific app is using the proxy as intended. Check the client, subscription configuration, and remote service separately.
Shadowsocks, VMess, Trojan, VLESS, Hysteria2, and TUIC are different proxy protocols or solutions, not Android power-efficiency ratings. Whether a client supports them depends on its core and version. Hysteria2 and TUIC are based on QUIC and generally depend on UDP network conditions; their names alone do not mean they will be faster or use less power.
Similarly, IEPL dedicated lines, relays, and direct connections describe how routes are organized, not an app's background permissions. A direct connection usually means the device connects to the proxy entry point itself; a relay passes through a forwarding entry point first. IEPL refers to a dedicated-line connection, though the actual path depends on the service details. Switching routes may improve the network path, but it cannot fix a system that terminates the client process.
Compare by use case, not just feature names
Client interfaces may use different labels. When choosing one, check whether it can handle the task you need instead of simply looking for boxes marked “rules supported” or “keep alive supported.” The table below is a checklist, not evidence that any particular product has passed testing.
| Use case | Check first | How to verify | What this does not prove |
|---|---|---|---|
| Keep access after locking the screen | Foreground service, background activity, battery restrictions | Unlock the screen, reopen the app, then check access and logs | A persistent notification does not prove the remote service is reachable |
| Extended use on the go | Reconnect frequency, background traffic, device heat | Keep the task and network conditions constant, then compare battery records | A single battery change cannot be attributed to a protocol |
| Proxy only selected apps | App list, default action, domain rules | Test apps on both the included and excluded lists | A browser's exit route does not represent every app's route |
| Switch access networks often | Network-change detection, automatic recovery, failure alerts | Send a new request after changing networks | A connected status in the interface does not mean the session has recovered |
Also consider maintenance, configuration compatibility, and whether error messages are clear. A client that only offers a connect button but does not show the current node or failure reason makes troubleshooting harder. A successful import does not mean every subscription field is supported. If rules are missing or a protocol is incompatible, check the import message first.
Background reliability: find where the connection fails
A connection dropping when the screen locks may be caused by a terminated process, a temporary network outage, a remote timeout, or restrictions on the target app's background activity. Start by noting what happens: does the client notification disappear, do the logs restart, can other apps connect, and does reconnecting manually restore access? Do not turn off every battery-saving option at once, or it will be hard to tell which change helped.
- Open the system app settings and find the client's battery and background activity options. Make sure it is not restricted from running in the background. Menu names vary by manufacturer, so follow the labels on your device.
- If the system offers controls for auto-start, linked launch, or background activity, check the permissions the client needs. Locking the app in the task list is only an additional measure, not a substitute for system permissions.
- Check whether the client uses a foreground service. Notification permissions and service requirements vary by system version; a visible notification alone does not indicate a healthy connection.
- After locking the screen, reopen the target app and send a request, then review the client logs. Test network switching separately rather than changing multiple variables at once.
- If only one app stops receiving messages, check that app's own background network and battery settings instead of immediately blaming the proxy route.
Android generally allows only one user VPN service based on VpnService at a time. Local firewalls, ad blockers, and proxy clients using the same type of interface may replace one another. If a connection closes as soon as it opens, check whether another network tool is taking control instead of repeatedly switching nodes.
Battery settings: how to run a repeatable test
Power use is not a fixed property of a protocol name. Signal strength, screen brightness, video decoding, data transfer, reconnects, and background sync all affect results. To compare clients, use the same device, similar battery levels, the same access network, and the same task where possible. Keep the screen state consistent and record the test start and end times along with the system battery statistics.
Separate an idle connection from sustained data transfer. For the first, observe locked-screen standby, background wake-ups, and reconnects. For the second, compare battery changes, heat, and transfer completion while accessing the same content. Do not compare one client's video playback with another client's idle standby. Alternate the test order as well to reduce bias from device temperature and network timing.
The system battery page may attribute some network use to the target app or system components, so do not look at the proxy client alone. If power use seems unusual, check traffic records and logs for repeated handshakes, overly frequent health checks, continuous sync tasks, or retries caused by an unreachable remote service. A single sample can offer a clue, but it cannot establish a reliable ranking.
- ✅ Record the device system, client version, route, rules mode, and test task so the results have context.
- ✅ Keep the access network and screen state comparable, and check total device power use and background activity.
- ✅ Save reconnect, timeout, and network-switch records before interpreting battery differences.
- ❌ Do not treat perceived heat, one successful recovery after locking the screen, or one sudden battery change as a performance finding.
Per-app proxy: how app lists and routing rules work together
Per-app proxy settings generally determine at the system interface layer which apps enter the virtual network; domain or address rules then determine how the proxy engine handles requests that enter it. These operate at different layers. If an app is excluded from the interface, internal domain rules usually cannot take over its requests.
Common modes include “proxy only selected apps” and “bypass selected apps.” Check the default action before changing settings; do not rely only on whether an app is checked in the list. If only specific apps should use international routes, start by adding them to the included list. If most apps should enter the rules engine, carefully review the excluded list and default route.
To verify the setup, open apps on both the included and excluded lists, check whether the client records the corresponding connections, and inspect the result in the target app if it has an exit-route diagnostic. A browser exit check only represents that browser's requests at that time. Links inside an app may open in an external browser, so check which app actually made the request.
End old connections before testing and reopen the app to avoid misleading results from connection reuse. With work profiles or separate user spaces, an app with the same name may be a separate instance; check its settings in the relevant environment. Do not switch all traffic to direct connections just to make one app work if that conflicts with the intended routing.
Subscription imports and DNS: verify after connecting
One key difference between Android and desktop clients is the system's background policy and how VpnService takes control. Even when different platforms use similar cores, their menus are not interchangeable. To get a client and subscription, sign in to the user panel; see the getting started guide for the entry point. Download the app through a channel provided by the panel rather than starting troubleshooting with an installer from an unknown source.
When importing a subscription, confirm that the link format is compatible with the client, then check the update result, node list, and rule status. Subscription links may contain access credentials, so do not paste them into public chats, screenshots, or third-party conversion pages. Before sharing logs, remove subscription URLs, tokens, and other account information.
DNS leak checks concern whether domain lookups follow the expected resolution path; simply checking whether a DNS server is local is not enough. Android Private DNS, encrypted DNS built into an app, and the client's DNS policy may all be active at once, so consider how the client takes control. Encrypted DNS protects the transmission, but does not automatically prove that it uses the proxy exit.
Start by checking the client's DNS mode and logs, then use a trusted diagnostic page as an additional check. A browser test does not represent every app; caching, app-specific resolution, and existing connections can also affect the results. If a page loads but an app fails, check its domain resolution, routing-rule matches, and UDP support as well. Do not assume the issue is resolved based only on the exit address.
VPNHY's known details and limits
VPNHY's stated service details include coverage in 100+ countries, 180+ routes, no device limit for simultaneous connections, and bank-grade encryption as a core security message. No email address is required; an account can be created with a username and password. These details help clarify service scope and account requirements, but do not replace testing background reliability, battery use, and per-app proxy routing on a specific Android device. They also do not mean every route supports the same protocols.
For budgeting, monthly subscriptions are ¥9.9 / 60GB, ¥18 / 250GB, and ¥28 / 500GB. Monthly data resets each month on the activation date; the price difference for a mid-cycle upgrade is converted into the remaining days. Data packages are ¥158 / 300GB, ¥358 / 1000GB, and ¥658 / 3000GB, available until used and never expiring. No device limit does not mean unlimited data, so choose based on your actual usage.
Payment methods include Alipay, WeChat Pay, and USDT. A full refund for any reason can be requested within 60 days of the first payment. Check the plans page for package details. The settings available in the Android client depend on the version and interface currently offered in the panel; do not treat the general checks in this guide as a confirmed feature list.
