Shipmate, what tsac is saying is that even though your phone says you are turning it off by pushing the red (end call) button, and after pushing that button it even tells you that it is powering off, what it is really doing is going into standby mode, just like your computer goes into standby mode when you put it to sleep.

The Blackberry phone (which is really more of a small computer, not a phone) is still performing many background functions like searching for cellphone signals, running wi-fi and bluetooth, uplinking downloaded application info, etc. while it is in standby mode.

The only way to completely shut off a Blackberry is to take out the battery, and many people do this at night to clear system memory, shut off applications that are running in the background, and start out the day with the available memory maximized. This is what is called a hard reset.

What tsac is also warning you about is that now that you have had issues with your batteries completely discharging (a very bad thing for a blackberry battery) you may still have battery issues even though you have changed your shut down procedure from using the red (power off/end call) key to pulling the battery (hard reset). The problem may continue because the batteries are damaged.

Try changing how you shut down at night, and if the battery problem continues get a new battery and that should solve your problem.
