Hello, I have a new 15" MBP Aluminum. It's the 2.53 GHz with a 320GB 7200 HD. I don't seem to be getting very good battery life. I just unplugged the power cord and it estimates 2:50. I only have Safari and Mail running. I am connected over WiFi and Bluetooth is turned on. The screen brightness is at the lowest setting. I am running in Power Saver mode with the lower powered video card. I conditioned my battery when I first got it. Here is what iStat provides: Cycles 8 Health 100% 99%, 2:50 remaining. Here is the Power information from the System Profiler. Model Information: Serial Number: SMP-xxxxxxxx-xxxx-xxxx Manufacturer: SMP Device name: bq20z951 Pack Lot Code: 0000 PCB Lot Code: 0000 Firmware Version: 002a Hardware Revision: 000a Cell Revision: 0100 Charge Information: Charge remaining (mAh): 4282 Fully charged: No Charging: No Full charge capacity (mAh): 4643 Health Information: Cycle count: 8 Condition: Good Battery Installed: Yes Amperage (mA): -1571 Voltage (mV): 12094 The other day, I unplugged the MBP and took it to work. I only turned it on when I was teaching. I used the mini adapter to connect the MBP to the projector. After I taught, I closed the lid and when I got home the power was down to 10%.!! So I was only able to get about 1.5 hours out of it for the day. The screen was on full brightness when I was teaching however. Are other getting less than 3hrs battery life? Does this sound about right? Any suggestions? Cheers.
