It started from last Friday, when I plugged the droid into my computer USB port to charge it. The charging couldn't keep pace with the power consumption, and eventually the phone shut down automatically without waking up on itself for about an hour. From then on, I cannot even rely on car charger or computer charging to make a phone call when the battery is below 5%. Today, I left the phone charging via computer for an hour. After I came back, it still showed 40%, no increase at all, but the upper part (guess where the CPU is?) is hot.
I felt something is just not right.
