Hello Foxx, Sorry for the delay, the restarts have stopped since the day before yesterday ie. From the time I changed the network settings. Thanks for letting me know about the issue regarding similar problems faced by BB 9900 users.. About the signal reception, I get 3-4 out of 5 bars in my home so is that the reason behind the battery depletion ?? Are any of your friends having BB 9320's ?? If possible, please let me know about the battery performance in their phones.
