A number of times I have been using my phone and suddenly the red LED indicates minimal battery charge left. It has mystified me as I don't run my battery down very low and charge it every night, I don't usually come close to wearing it out.
I finally realized it was going from maybe 60-70% charged to 5% in a sudden drop. Removing the battery and replacing it would show the 60-70% charge again.
This morning I got up and the phone was in the charging media dock but the red light was on, showing no battery life. ??? I removed the phone from the dock, put it back on again, checked all the connections to make sure it was actually plugged in and the indicator went to 100% charged. ???
I am wondering if anyone else has experienced this. I wonder if I need to shut the phone off every once in a while, I don't usually unless a problem like this comes up. But it's very weird and has impacted my ability to use the phone at times.
