1. Fixing Slow Charging Issues

33W isn't the fastest, but it shouldn't take 2 hours. Let's fix it.

Steps 1-3: Charge Speed

Clean Port: Use a non-conductive toothpick to remove lint from the USB-C port. Accumulated dust prevents fast charging pins from connecting.
Optimized Charging: Go to Settings > Battery > Optimized Night Charging. Turn it OFF if you charge during the day. It slows down charging to save battery health.
Temperature: Avoid charging when the phone is hot (after gaming). SUPERVOOC slows down above 38°C to prevent damage.

2. Solving Lag & Freezing

The Dimensity 6020 is decent, but 8GB RAM can fill up fast.

Steps 4-6: Performance Boost

RAM Expansion: Go to Settings > About Device > RAM. Set expansion to +4GB. Don't set it to +8GB as it puts too much load on the UFS 2.2 storage.
High Performance Mode: Go to Battery > Advanced Settings. Turn ON "High Performance Mode" only when playing games like BGMI. Keep it OFF otherwise.
Animation Scale: Go to Developer Options. Set all three animation scales to 0.5x. This makes the UI feel twice as fast.

3. Optimizing 5000mAh Battery Life

ColorOS has many background services. Let's restrict the unnecessary ones.

Steps 7-9: Power Saving

App Freeze: Go to Battery > More Settings > App Freeze. Freeze apps like Instagram and Snapchat. They won't run in the background until you open them.
Screen Refresh Rate: If battery is priority, set Refresh Rate to "Standard" (60Hz) instead of "High" (90Hz). This saves about 10% battery.
Power Saving Mode: Enable "Power Saving Mode" automatically at 20%. It restricts background sync and visual effects.

💡

OPPO Tip: Use the "Phone Manager" app > "Clean Storage" weekly. It removes cache files that slow down the system.

4. Fixing Camera Blur & Focus

The 50MP camera needs good light. Blur often happens due to software processing delay.

Steps 10-12: Clear Shots

AI Retouching: Turn OFF "AI Scene Enhancement" if photos look unnatural or take too long to save.
Tap to Focus: Always tap the subject on screen before shooting. The autofocus on budget sensors can be slow in low light.
Clear Cache: Long press Camera Icon > App Info > Storage > Clear Cache. This resets any buggy camera settings.

Warning: Avoid using the phone while charging. It heats up the battery, which triggers thermal throttling and slows down everything.

Additional Maintenance (Steps 13-15)

Step 13 (App Lock): Use the built-in "App Lock" instead of third-party lockers. It's integrated into the system kernel and uses zero extra battery.
Step 14 (Restart): Restart your phone every 3 days. It clears the RAM buffer and keeps the UI smooth.
Step 15 (Update): Check Software Update. OPPO releases stability patches frequently for A-series phones.
