Hi guys;

I've bought myself a new BB8820 in the beginning of januari. The first couple of charges I've let it stay plugged in after the battery was charged fully (I read somewhere this would benefit my battery's life span). After those charges I started charging when the battery was lower than 30% or in extreme cases when the "battery low" warning appeared on my display.

Since the beginning of this week (when I unlocked the BB maps application) my battery is just draining insanely; I fully charged it this night; unplugged it from the charger 6 hours ago and already I'm down to 75% battery life.
I did not leave any application open (I checked this) and I only made like 2 phone calls of 5 minutes today.
Prior to this I charged it on sunday and it ran out on tuesday night and you should know that in between this it had been connected to my desktop for several hours when working on the unlocking of the BBmaps.

Is this a common issue for the BB8820 or is my battery just dead?

Thank you in advance for your answer;

Miguel
