Full Charge Capacity (mAh): 5216 Remaining Capacity (mAh): 5177 Amperage (mA): -1412 Voltage (mV): 12375 Cycle Count: 10 I've only had it about 3 weeks. Is the drop in capacity normal? Should I not leave it plugged in? I know that batteries tend to give out rather quickly if you leave it plugged in all the time. Should I only charge when I need to? Thanks.
