You will need to purchase a new battery. You can get them online at Amazon.com. They have everything, the prices are reasonable, and you can get them fast if you pay extra for shipping, or you can get free shipping if you purchase other items so that your order total is over $25.00.
Turn off your phone and remove the back cover to see the battery. Just search for the part number on Amazon under Electronics.
It is not unusual to requite a battery replacement after about two years If my answer has been helpful to you, please be sure to rate my services. This is how I get paid for sharing my knowledge and giving my advice.
