I purchased my Z2 just two weeks ago. Yesterday, I went to the beach and used the phone underwater. I went back home and connected the phone to the charger and jacked the headset at the same time. I notice that the red led was flickering as if there is some thing wrong I disconnected the charger an realized that there wast some water inside the headset jack. after that, I was sure the was no drop of water inside the jack and connected the charger again and every thing went- the led began red then orange and finally green at full charge.
Today, I connected the charger when the battery was bellow 7 and the led continued to be green ahead.
