I fully charged my BB before I went to bed last night, but when I woke up this morning..my phone was off! I tried to turn in back on, but it didnt..so I plugged my phone back in to the battery cord and turns out my BB battery drained out over the night....is that possible? did it ever happen to anyone?
Overnight is certainly long enough to fully discharge your battery if something is providing a load. If an app is keeping the screen on, or continuously accessing the internet, or you have a weak signal that keeps the phone at high output power, then it can happen. Did you leave any app running overnight that you don't normally?
