Honor 5x battery not charging

A

AC Question

7 days ago i dropped my honor 5x in water i had taken it out quickly and dried it with hair dryer and put it in rice for 7 days

After 7 days when i connected my charger to phone it shows a red battery sign and also led started blinking red after 3 or 4 minute led goes blue and screen goes black.

I again connected charger after some time but same happened again and again

Why it is not charging is it a sign of dead batter due to water

Please help me
