    I've had my XPS1645 for just over 5 months now. I usually run on AC power, but use battery power a few times per week. According to CPUID, the designed capacity is 7650 mWh, and my full charge capacity is 6550 mWh.

    I have a secondary battery which gets about the same use as my primary, it says designed capacity 7800 mWh and full charge capacity 7440 mWh.

    Are those numbers normal? Or is the primary battery biting the dust already? (I'm also not sure why the two batteries have different designed capacities). Thanks!

    No surprise. I've been using mine for about 5 months now and it has 9% wear on it. It's natural.

    I have got my xps for a month now. In 10 days it became 10% wear but it has been on that level since then... equivalent to 6882 mWh
