Keeping your screen brightness too high can drain your phone's battery much faster.

Apps running in the background continue to use power even when you're not actively using them.

Location services, Bluetooth, Wi-Fi, and mobile hotspot consume battery if left on unnecessarily.

Gaming, video streaming, and video calls are among the most power-hungry activities on a smartphone.

An outdated operating system or apps may reduce battery efficiency and increase power consumption.

Poor network coverage forces your phone to work harder to maintain a signal, which drains the battery faster.

Too many notifications and widgets refreshing in the background can also impact battery life.

As a phone battery ages, its capacity naturally decreases, leading to shorter battery backup.
