Patel, 87, passed away on Monday, a post on her official Instagram page, 'Cricket Daadi', stated.
"With a heavy heart, I inform you that our beautiful grandmother took her last breath on January 13th at 5:30 pm," the post read.
"She was such a cute little lady, it is true that small things come in small packages. Our dadi was a pleasure, it was / is really exceptional. It was our world. I want to thank you all for making you feel special last year. She loved the attention."
The BCCI took to twitter to offer condolences.
"#TeamIndia's Superfan Charulata Patel ji will always remain in our hearts and her passion for the game will keep motivating us. May her soul rest in peace," it posted.
The wheelchair-bound Patel came to limelight when she was seen cheering for India by blowing a vuvuzela during a World Cup game against Bangladesh on July 2 last year in Birmingham.
Her enthusiasm prompted Kohli and Sharma to personally thank Patel. They showed their gratitude by seeking her blessings after India's win.
The International Cricket Council (ICC) also posted a message on its official Twitter page to condole her death.
"R.I.P Charulata Patel ji, the 87-year-old superfan who cheered India on at #CWC19PTI," the world body stated.
