Why is my BlackBerry 9900 vibrating with the phone off?

today while in the bathtub my bb dropped into water i quickly ripped the battery apart and started to dry the phone after sometime i placed my battery in the phone and nothing happend so to revive it i put it to charge the phone rebooted and asked my bb id i was typing the password as soon as i noticed the phone was hanged so i disconnected the phone from the power source and took out its battery now when i insert the battery it doesnt turn on but when i connect it to power source it starts to vibrate

DO NOT reinsert the battery ! Try some rice and put the phone in there for a full day at least. Submerge it fully in the rice. Put the battery in the rice as well. It may already be too late. Sorry about that.

You probably need to get a new phone now. Try BlackBerry Classic. :D
