Whether you’re aiming for sharper photos, faster response times, or better battery endurance, this guide highlights 17 practical Oppo A78 5G tips and tricks for Indian users in November 2025.
Optimize Battery Performance
The Oppo A78 5G is already known for its strong 5000mAh battery, but small adjustments can make it last even longer.
Turn on Super Power Saving Mode
Go to Settings → Battery → Power Saving Mode, then enable Super Power Saving Mode. It limits background apps and screen brightness but extends standby time dramatically, useful when traveling or during long workdays.
Use Sleep Standby Optimization
Under Battery → Advanced Settings, activate Sleep Standby Optimization. This feature restricts background power usage when the phone is idle overnight, ensuring minimal drain while you sleep.
Limit Background App Usage
In Battery → App Battery Management, manually restrict high-drain apps like Instagram or YouTube from running in the background. This improves screen-on time by up to 20%.
Enable Battery Health Protection
To extend battery lifespan, enable Battery Health Protection under Battery → More Settings. It prevents overcharging by keeping the charge limit near 80–90%, perfect for users who charge their phone overnight.
Enhance System Speed and Responsiveness
Activate High Performance Mode
Go to Settings → Battery → More Settings → Performance Mode, and choose High Performance. This mode allows the CPU to run at its full potential, making animations, gaming, and app switching faster.
Clear Cache Regularly
Use Device Manager → Storage Cleaner weekly to remove cache files that accumulate and slow down performance. This helps the system maintain consistent speed.
Use RAM Expansion Feature
Enable RAM Expansion under About Device → RAM → Expand RAM. You can add up to 8GB of virtual RAM, making multitasking smoother, especially for gaming and switching between heavy apps.
Disable Unnecessary Animations
Navigate to Settings → About Device → Developer Options, and reduce Window Animation Scale and Transition Animation Scale to 0.5x. This speeds up transitions and gives a faster, snappier UI experience.
Improve Camera Quality and Results
Use AI Scene Enhancement
Under the Camera app → Settings, turn on AI Scene Enhancement. This feature automatically detects subjects—like food, nature, or portraits—and adjusts exposure, color balance, and sharpness for professional-looking shots.
Activate HDR Mode
For better lighting in tricky conditions, toggle HDR Mode to Auto. It helps balance bright backgrounds and darker subjects, especially during outdoor photography.
Switch to 50MP High-Res Mode
When shooting detailed images, open the Camera app and select 50MP Mode from the top menu. It delivers sharper images ideal for cropping or printing without losing quality.
Use Portrait Mode with Filters
In Portrait Mode, experiment with Oppo’s built-in filters. For natural results, select Natural Light or Warm Tone. For Instagram-ready results, use AI Portrait Retouching to subtly enhance skin tones.
Adjust White Balance Manually
In Pro Mode, fine-tune the White Balance (WB) for indoor and outdoor lighting. This manual tweak eliminates yellow or blue tints in photos, resulting in more accurate colors.
Use the Grid for Framing
Activate the Grid Lines under Camera Settings. It helps align your shots perfectly using the rule of thirds, improving composition dramatically.
Boost Gaming and Multimedia Experience
Turn On Game Focus Mode
Go to Settings → Game Space → Game Focus Mode. It disables notifications, boosts CPU performance, and improves touch response during gaming sessions for a distraction-free experience.
Enable Dolby Atmos Sound
For richer sound, head to Settings → Sound & Vibration → Dolby Atmos and choose Smart Mode. It automatically adjusts the audio based on your content — music, video, or games.
Adjust Refresh Rate for Smoothness
Under Display → Screen Refresh Rate, select High (90Hz). It enhances scrolling smoothness, animation fluidity, and gaming responsiveness without heavily impacting battery.
Useful ColorOS 14 Customization Tips
Use Smart Sidebar for Multitasking
Enable Smart Sidebar under Special Features. You can access apps, screenshots, and tools directly while using other apps, making multitasking easier.
Customize Always-On Display
Go to Settings → Personalizations → Always-On Display, and choose from dynamic clocks or text. You can even add your signature or favorite quote.
Optimize Privacy and Security
Under Privacy Dashboard, check which apps access your camera or microphone. Toggle off permissions for apps that don’t need them to maintain data privacy.
