why does my phone battery die so fast

The main reasons why a phone battery dies so fast include background apps running continuously, high screen brightness, frequent push notifications, extensive use of location services, outdated software, poor battery health due to aging, and exposure to extreme temperatures. Additionally, poor cellular signal strength can cause the phone to use extra power trying to maintain a connection, accelerating battery drain. Other factors include keeping connectivity features like Wi-Fi or Bluetooth on when not in use, vibration and haptic feedback, auto-sync and backups running frequently, and potentially malware running in the background. It is also important to use a proper charger, as faulty chargers can affect battery performance. To extend battery life, reducing screen brightness, closing unnecessary background apps, limiting push notifications, updating the operating system, avoiding extreme temperatures, and ensuring good cellular signal are effective measures.
