hi there guys my phones recently got water damage ( and by water damage i mean that a bit of water got on the front due to rain and the phone shut off..) basically ive opened the phone replaced the battery and the same thing happens..it goes straight to 100 percent when i plug the charger in but when i disconnect the flex cable from the motherboard whilst its charging the phone then shuts off as if ive taken the charger out..i need help if its the battery (which has been replaced) OR the charging flex cable???
