Many people believe that keeping Bluetooth and Wi-Fi on drains their phone's battery quickly. This is not entirely true. In modern smartphones, these features consume very little battery power.

Many people think that keeping Wi-Fi and Bluetooth on drains their phone's battery quickly. Therefore, they turn them off every time after use. But does keeping them on really have a significant impact on battery life? The simple answer is no. In fact, Bluetooth and Wi-Fi are low-energy radios, and keeping them on or off doesn't significantly affect battery life. Let's learn more about this in detail.

The problem is solved in modern smartphones

The advice to turn off Bluetooth and Wi-Fi has been given since the early days of smartphones. However, due to advancements in technology, these features don't significantly affect battery life in modern smartphones. Modern smartphones use Bluetooth Low Energy, which consumes negligible battery power even when active. Bluetooth consumes only 2.5 mW of energy, which means it would take approximately 3 months for the battery to drain completely just from Bluetooth usage. Similarly, Wi-Fi has also become energy-efficient and consumes less battery power compared to mobile data. So, if you are using Wi-Fi instead of a mobile connection, your phone's battery will last longer.

What drains the battery the most?

If you want to extend your phone's battery life, turn off location-based services. Also, disable Super HDR and Always-On Display. Similarly, reducing brightness, using dark mode, and decreasing screen timeout can help save battery. Even when you are not using your phone, several activities run in the background. Limiting these activities can also help extend your phone's battery life.
