### Stop Background Processes
**List all running processes:**
```bash
adb shell ps
```
**Check memory usage by process:**
```bash
adb shell top -s 6
```
**Check CPU usage by process:**
```bash
adb shell top -s 9
```
**Kill specific process by PID:**
```bash
adb shell kill
```
### Prevent Apps from Running in Background
**Stop specific app from running in background:**
```bash
adb shell cmd appops set <package-name> RUN_IN_BACKGROUND ignore
```
**Force stop an app:**
```bash
adb shell am force-stop
```
**Example - Stop Facebook from running in background:**
```bash
adb shell cmd appops set com.facebook.katana RUN_IN_BACKGROUND ignore
```
## Bloatware Removal and App Management
### List Installed Packages
**List all packages:**
```bash
adb shell pm list packages
```
**List third-party packages only:**
```bash
adb shell pm list packages -3
```
**List system packages only:**
```bash
adb shell pm list packages -s
```
**Search for specific app:**
```bash
adb shell pm list packages | grep
```
### Uninstall/Disable System Apps
**Uninstall system app (user-level, can be restored):**
```bash
adb shell pm uninstall --user 0
```
**Disable system app:**
```bash
adb shell pm disable-user --user 0
