Common Causes of Battery Drain

1. Too Many Background Apps

Apps keep running even when you’re not using them, silently eating battery.

2. High Screen Brightness

Keeping brightness at max drains battery quickly, especially outdoors.

3. Poor Network Signal

When your phone struggles to find signal, it consumes more power.

4. Outdated Apps or Software

Old apps can be buggy and inefficient.

5. Battery Health Degradation

Over time, batteries naturally lose their capacity.
