Sure it could, but you have a much later Pearl OS than any out there that I've heard of (Verizon has 60, Telus 65, Bell 66, you have 71). So if there is an OS fix related to battery life, it doesn't appear to be out yet.

To keep this thread on topic, there's a thread on battery life at the link below...you might want to read it and post your info (usage, battery life you're getting, things you've tried, etc.).
