Over the last few weeks I have noticed a significant change in the battery life on my 9930. A few months ago I started using it as a mobile hotspot at my new house. That zapped it for obvious reasons and I only leave hotspot on when I'm using my tablet or computer.
The last few weeks it has started jumping from 70% to 5% or below. Last night specifically I had it charged to 100, was sitting at happy hour for 2 hours and had ubersocial open, the browser a little and texting. It jumped to almost gone. As soon as I plugged it in, it went to 65%.
Do you think this is a battery issue or a phone issue?
To answer the "did I get it wet" question...yes, the white box is red now, but that happened several months ago.
