I am using BB 9900 for last over a month in Pakistan using a Telenor connection.
Although the battery life is little as compared to the earlier used models, I have kep all applications closed.
A couple of times it has happened that the set has become warmer and battery drained quickly.
I have seen similar complaints by other users on other forums as well regarding battery life.
Pls advise any thing to get battery life enhanced to last atleast 24 hours.
