What kind of battery life should I expect out of a 2.5 year MacBook Pro? It's a 15" late-2008 model (first unibody model) with a 2.8 GHz Core 2 Duo and 4 GB RAM and a 128 GB SSD. I started the day with a full overnight charge. Used it for about 25 minutes at my last appointment. Been sitting here at lunch and working for about 1:40. Started the day with it showing 3:05 remaining. Now I'm at 0:44. Guess that makes about 2:00 use so far and only have 0:45 left. If I Option-Click the battery meter it says Condition:Normal. I acquired this machine from the estate of one of my clients. I don't know how well the battery was cared for. I do know that the machine saw pretty light usage as this was one of many Macs he used. Energy Saver prefs say Graphics - Better battery life. I've been doing mainly Firefox web browsing with it for the last two days. An XP VM has been running under Fusion but not really in use (maybe this is draining just being there). Anyway, it looks like I'm getting 2.5 hours. I believe this machine was marketed as going for 5 hours. Is it time for a new battery or is that just the way it is?
