Why your phone is taking so long to charge, and how to speed it up

• There are several reasons why your phone might be taking longer than usual to charge.
• For a faster charge, plug your phone directly into a wall outlet — don’t use a wireless charging pad or a computer’s USB port.
• You can also charge your phone faster by turning it off, or simply not using it while it charges.
• A damaged charging cable or a dirty connection port can also slow down the charging process.
