Pre-Test Preparation

Step-by-Step Setup:

1. Charge Device
   - Battery: 50-100%
   - Keep charger plugged in during test
   - Prevents thermal throttling from charging

2. Close Background Apps
   - Recent Apps → Swipe away all apps
   - Settings → Apps → Force stop heavy apps
   - Disable auto-sync temporarily

3. Enable Performance Mode (if available)
   Samsung:
   - Settings → Battery → Power mode → High performance

   OnePlus:
   - Settings → Battery → Performance mode

   Xiaomi:
   - Settings → Battery → Performance

   Google Pixel:
   - No performance mode (uses adaptive battery)

4. Disable Power Saving Features
   - Adaptive brightness → Off (set manual brightness 50%)
   - Battery saver → Off
   - 5G → Off (use WiFi for stability)
   - Location → Off
   - Bluetooth → Off

5. Clear Browser Cache
   Chrome:
   - Settings → Privacy → Clear browsing data
   - Select "Cached images and files"
   - Clear

6. WiFi Connection
   - Use stable WiFi (not mobile data)
   - 5GHz band preferred
   - Close to router

Mobile Test Execution

Running the Benchmark

Mobile-Specific Instructions:

1. Open Browser in Full Screen
   - Chrome: Tap address bar → select full screen option
   - Avoid split-screen or floating windows

2. Prevent Screen Lock
   - Settings → Display → Screen timeout → 30 minutes
   - Keep device unlocked during test

3. Optimal Testing Position
   - Place device on flat surface (not in hand)
   - Allow air circulation around device
   - Avoid direct sunlight or heat sources
   - Room temperature environment (20-25°C)

4. During Test (5-7 minutes)
   ❌ Don't touch screen
   ❌ Don't rotate device
   ❌ Don't receive calls/notifications
   ✓ Let test complete uninterrupted

5. Monitor Thermal Behavior
   - Device will warm up (normal)
   - If too hot to touch → cooling issue
   - Performance may decrease after 3-4 minutes (thermal throttling)
