## ✨ Features
- **Automated Installation**: One-command setup for TLP and PowerTOP
- **Optimized Configurations**: Pre-tuned settings for maximum battery life
- **Monitoring Tools**: Real-time battery and power consumption monitoring
- **Power Analysis**: Detailed PowerTOP reports and recommendations
- **Profile Management**: Easy switching between power profiles
- **Safety First**: Backup and rollback capabilities
## 🚀 Quick Start
### 1. Install TLP and PowerTOP
```bash
# Clone or download this repository
cd battery_life
# Run the installation script
./scripts/install.sh
```
### 2. Monitor Your Battery
```bash
# Show current battery status
./scripts/battery-monitor.sh
# Watch battery status in real-time
./scripts/battery-monitor.sh --watch
```
### 3. Analyze Power Consumption
```bash
# Generate a PowerTOP report
./scripts/powertop-analyze.sh
# Apply automatic optimizations
./scripts/powertop-analyze.sh --auto-tune
```
### 4. Manage TLP Settings
```bash
# Show TLP status
./scripts/tlp-manager.sh
# Get optimization recommendations
./scripts/tlp-manager.sh --recommendations
# Switch to power saving profile
./scripts/tlp-manager.sh --profile powersave
```

## 🛠️ Detailed Usage
### Installation Script
The installation script (`scripts/install.sh`) automatically:
- Installs TLP and PowerTOP packages
- Configures systemd services
- Applies optimized settings
- Creates backup of existing configurations
- Installs additional power management tools
**Features:**
- Automatic system detection
- ThinkPad-specific optimizations
- Safe installation with rollback options
- Comprehensive logging
### Battery Monitor
Real-time battery monitoring with detailed information:
```bash
# Single status check
./scripts/battery-monitor.sh
# Continuous monitoring (updates every 5 seconds)
./scripts/battery-monitor.sh --watch
```
**Information displayed:**
- Battery capacity and status
- Charging/discharging time estimates
- Power consumption
- AC adapter status
- System efficiency metrics
- Power saving tips
### PowerTOP Analysis
Generate detailed power consumption reports:
```bash
# Generate 60-second HTML report
./scripts/powertop-analyze.sh
# Custom duration and format
./scripts/powertop-analyze.sh --duration 120 --format html
# Apply automatic optimizations
./scripts/powertop-analyze.sh --auto-tune
# Show latest report in browser
./scripts/powertop-analyze.sh --show-report
```
**Report formats:**
- HTML: Interactive web-based reports
- CSV: Data for spreadsheet analysis
- TXT: Plain text for terminal viewing
### TLP Manager
Comprehensive TLP configuration management:
```bash
# Show current TLP status
./scripts/tlp-manager.sh --status
# Display configuration details
./scripts/tlp-manager.sh --config
# Get optimization recommendations
./scripts/tlp-manager.sh --recommendations
# Switch power profiles
./scripts/tlp-manager.sh --profile powersave|balanced|performance
# Force battery/AC mode
./scripts/tlp-manager.sh --toggle-mode
```
## ⚙️ Configuration Details
### TLP Configuration
The optimized TLP configuration (`config/tlp.conf`) includes:
- **CPU Management**: Aggressive power saving governors
- **Disk Settings**: Optimized APM levels and timeouts
- **Graphics**: Power-efficient GPU settings
- **USB**: Smart autosuspend with device blacklists
- **Audio**: Power saving for sound devices
- **Battery Thresholds**: Smart charging limits (ThinkPad)
- **Radio Devices**: Automatic wireless management
### Key Optimizations
1. **CPU Scaling**: Uses `powersave` governor on battery
2. **Frequency Limits**: Reduces max CPU frequency on battery
3. **Turbo Boost**: Disabled on battery to save power
4. **Disk Power Management**: Aggressive APM settings
5. **USB Autosuspend**: Enabled with smart device handling
6. **Wireless Management**: Auto-disable unused radios
7. **Battery Charging**: Smart thresholds to extend battery life
## 🔧 Customization
### Modifying TLP Settings
1. Edit the configuration file:
```bash
sudo nano /etc/tlp.conf
```
2. Or modify the template and reinstall:
```bash
nano config/tlp.conf
./scripts/install.sh # Will backup and apply new config
```
### Adding Custom Optimizations
Create additional scripts in the `scripts/` directory following the existing patterns. All scripts include:
- Error handling and safety checks
- Colored output for better readability
- Comprehensive logging
- Usage instructions
## 📊 Expected Results
Typical battery life improvements:
- **Light usage**: 20-40% improvement
- **Normal usage**: 15-30% improvement
- **Heavy usage**: 10-20% improvement
Results vary based on:
- Hardware configuration
- Usage patterns
- Existing system settings
- Battery age and health
## 🔍 Troubleshooting
### Common Issues
1. **TLP not starting**: Check service status with `systemctl status tlp`
2. **PowerTOP requires sudo**: This is normal for hardware access
3. **Settings not persisting**: Ensure TLP service is enabled
4. **Conflicts with other power managers**: Disable conflicting services
### Debug Information
```bash
# Check TLP status and configuration
sudo tlp-stat
# View TLP service logs
journalctl -u tlp.service
# Test PowerTOP without changes
sudo powertop --time=10
```
### Getting Help
1. Check the logs in `/var/log/` for error messages
2. Run `tlp-stat` to see current configuration
3. Use the troubleshooting commands in each script
4. Review the official documentation:
- [TLP Documentation](https://linrunner.de/tlp/)
- [PowerTOP Guide](https://01.org/powertop/)
## 🔄 Uninstallation
To remove all components:
```bash
./scripts/uninstall.sh
```
This will:
- Restore original configurations
- Remove installed packages (with confirmation)
- Clean up created services
- Preserve your data and reports
