Why is My Wi-Fi Automatically Disconnecting at Night

If your OPPO phone’s Wi-Fi automatically disconnects at night, don’t worry—it’s likely due to a built-in power-saving feature. Here’s why it happens and how you can stop it if needed.

What is Sleep Standby Optimization

Your OPPO phone has a Sleep Standby Optimization feature that helps conserve battery power. When enabled, the system learns your sleep patterns and disconnects Wi-Fi and mobile data during sleep hours to reduce power consumption. Once you wake up and turn on the screen, the network quickly reconnects.

While this feature is beneficial for battery life, it can cause delays in receiving notifications or messages overnight.

How to Turn Off Sleep Standby Optimization

If you prefer to keep your Wi-Fi connected at all times, you can disable this feature by following these steps:

1. Go to [Settings]

2. Tap [Battery]

3. Select [Power saving settings]/ [More battery settings]

4. Find [Sleep Standby Optimization]

5. Toggle it off

Once turned off, your Wi-Fi and mobile data will remain active even when your phone is in standby mode.
