Many people think that keeping Bluetooth and Wi-Fi on drains the phone's battery faster. This isn't entirely true. They consume very little battery power on modern smartphones.

Does keeping Bluetooth and WiFi on affect the battery more?

Many people believe that keeping Wi-Fi and Bluetooth on drains their phone's battery faster. Therefore, they turn them off after each use. But does keeping them on really have a significant impact on the battery? The simple answer is no. In fact, Bluetooth and Wi-Fi are low-energy radios, and being on or off doesn't significantly impact battery life. Let's explore this in detail.

The problem has been resolved in modern smartphones.

Keeping Bluetooth and WiFi off has been recommended since the early days of smartphones. However, due to technological advancements, these devices don't significantly impact battery life in modern smartphones. Today's smartphones use low-energy Bluetooth, which consumes minimal battery power even when active. Bluetooth consumes only 2.5 mW of energy, so it can take approximately three months for a battery to fully discharge using Bluetooth alone. Similarly, WiFi has become more energy-efficient and consumes less battery power than a mobile connection. Therefore, using WiFi instead of a mobile connection will result in longer battery life.

How does the battery discharge 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, lowering the brightness, using dark mode, and reducing the screen timeout can all help save battery. Even when you're not using your phone, many activities continue to run in the background. Limiting these can also help extend your phone's battery life.
