## Summary

To prevent Android from closing your VPN or accelerator, disable battery optimization, enable Always-on VPN, lock the app in recent tasks, and allow unrestricted background data usage.

### Step 1: Disable Battery Optimization for the App

Android’s **Adaptive Battery** or **Doze Mode** will aggressively close background processes for apps it thinks you aren't actively looking at.

1. Open your phone's **Settings**.
2. Go to **Apps** (or **Apps & Notifications** / **App Management**).
3. Find and tap on your **Accelerator App**.
4. Tap **Battery** (or **Battery Usage**).
5. Change the setting from *Optimized* or *Smart Control* to **Unrestricted** (or **Allow background activity**).
**Verification:** Open your app, start accelerating, lock your screen for 5–10 minutes, and unlock it. If the connection remains active in the status bar, this step was successful.

### Step 2: Turn On "Always-on VPN" in Android Settings

Android allows you to pin a VPN/Accelerator connection at the system level so the operating system never drops it.

1. Open your phone's **Settings**.
2. Tap **Network & Internet** (or **Connections** / **More Connection Settings**).
3. Tap **VPN**.
4. Tap the **Gear / Settings icon** next to your Accelerator app.
5. Toggle on **Always-on VPN**.
6. *(Optional)* Toggle on **Block connections without VPN** if you want to ensure your regular internet traffic doesn't bypass the accelerator if it momentarily drops.
**Verification:** Look at your status bar at the top of your screen. You should see a persistent key or shield icon that stays visible even when switching between heavy games or apps.

### Step 3: Lock the App in Your "Recent Apps" Menu

Many Android skins (Samsung One UI, Xiaomi MIUI/HyperOS, OPPO ColorOS, vivo OriginOS) will clear non-locked apps from memory when you swipe them away or tap "Clear All."

1. Swipe up from the bottom of your screen (or tap the **Recent Apps** button) to open your multitasking view.
2. Find the window for your **Accelerator App**.
3. Tap and hold the **app icon** above its preview card, or tap the **three dots (...)** in the corner.
4. Select **Lock** (you will see a small padlock icon appear on the card).
**Verification:** Swipe away all recent apps or tap "Clear All." Check if your accelerator stays open in the recent apps tray and retains its padlock icon.

### Step 4: Allow Background Data Usage

If Android restricts background data for your accelerator, the connection will time out even if the app process is technically still alive.

1. Open **Settings** > **Apps** > **Accelerator App**.
2. Tap **Mobile Data & Wi-Fi** (or **Data Usage**).
3. Turn ON **Background data**.
4. Turn ON **Unrestricted data usage** (this prevents "Data Saver" mode from throttling your accelerator).
**Verification:** Turn on Data Saver mode in your quick settings panel, then launch a game through your accelerator. The network delay/ping should remain low and stable without connection drops.
