Brief Hands-On Report--Battery Update 1.3 for 15" MacBook Pro, Is Battery Life Shorter?
Battery Update 1.3 updates battery firmware and addresses battery performance issues with the 15-inch MacBook Pro. Your computer's power cord must be connected and plugged into a working power source while running this update.
After the Battery Update has been installed, any additional batteries you put in your 15-inch MacBook Pro are automatically updated.
We have not been having any problems with the battery in our 15" MacBook Pro Core 2 Duo (LED). In fact, it's usable life is longer by at least 30 minutes than any other PowerBook G4 or Mac Book Pro that we have ever used. But we downloaded and installed Battery Update 1.3 via Software Update anyway and encountered no problems. The update required a restart.
In our preliminary testing, after the update the battery menu icon shows a lower battery life with a fully charged battery. If we disconnect the AC adapter with the MacBook Pro CD (LED) set to full conservation (screen brightness at last notch and nor disk use), the battery icon showed approximately 4 hours of battery life before the update. It now shows less than 3.5 hours under the same conditions. However, we have not performed any long-term use tests to confirm an actual shorter battery life. [Bill Fox]
