This is probably the most common mistake. We open one app, then another, without ever really closing the previous ones. Even in the background, some continue to refresh data, connect to the internet, or use the processor. The result: the battery is constantly draining. Getting into the habit of closing unnecessary apps and limiting their background activity can significantly improve battery life.
An incorrectly adjusted screen brightness
The screen is one of the most energy-intensive components of a phone. When set to maximum brightness, especially indoors, it consumes a significant amount of energy unnecessarily. Enabling automatic brightness adjustment or manually lowering the brightness as soon as possible is a simple but very effective habit. Also, consider disabling always-on display if your device has this feature: however aesthetically pleasing it may be, it is rarely necessary.
Bluetooth, GPS and Wi-Fi always active
We turn them on in the morning… and forget about them all day. Yet, Bluetooth, GPS, and Wi-Fi continue searching for connections, even when you're not using them. This constant searching drains the battery without you even realizing it. The best approach is to disable these features as soon as they're no longer needed, especially when you're traveling.
