• The bad battery: If your battery is old, or has been damaged, it may not hold a charge as well as it used to. Over time, batteries lose their ability to hold a charge, and will need to be replaced.

  • A draining phone: If your phone is constantly running apps or using power-hungry features, it can drain the battery faster than it can charge.

  • A slow charger: Some chargers aren't able to charge a phone as quickly as others. If you're using an older or lower-powered charger, it may take longer for your battery percentage to go up.

  • Your phone's settings: If you have your phone's power-saving features turned on, it can affect how quickly the battery charges. Try turning off any extra features or settings that might be draining your battery.
