    I just turned on my 13" MBP and got this message. Apparently, this is supposed to come up when there is only like 5% charge left. My battery indicator at the top of the screen said there was 22% charge left. Also, according to IStat, my battery's health has already dropped down to 97% after only about 2 weeks and 5 cycles.

    Is this normal? I'm going to try recallibrating my battery by fully charging it and then letting it fully drain. Is there a good chance that this solves this problem?

    to the reserve battery. mine is actually running on it now as well and from what i've seen over the past 2 months of owning my mbp, the 20% mark is the time when the reserve battery kicks in.

    as for the battery calibration, i've done it, and my battery health still fluctuates around 95%-97%.

    both your worries are normal.
