Hey, new here. I just bought a base-model 13" MBP and have an inquiry about the battery. The Apple site states it has 10 hours of batt. life. However, after a full charge my notebook mentions that just about 7 hours of life is remaining. Shouldn't it be showing 10? Here's my battery info if it helps: Battery Information: Model Information: Serial Number: 9G0230QZPD3MA Manufacturer: DP Device name: bq20z451 Pack Lot Code: 0000 PCB Lot Code: 0000 Firmware Version: 0201 Hardware Revision: 0002 Cell Revision: 0158 Charge Information: Charge remaining (mAh): 5475 Fully charged: No Charging: No Full charge capacity (mAh): 5825 Health Information: Cycle count: 3 Condition: Normal Battery Installed: Yes Amperage (mA): -1002 Voltage (mV): 12202 I'm quite a newbie so thanks for any help.
