When I calibrating my battery yesterday on my 2014 rMBP, I noticed a couple of issues, was wondering if they are normal: 1) When the battery was draining low, I did not get a low battery warning or anything like that. The laptop pretty much just shut off when it reached 0% (not even shut down gracefully, I just cut the power, and it had a fresh reboot when I plugged it in this morning again) 2) I was running a Flash video in Chrome to drain the last couple of percent faster. I noticed that the laptop got very sluggish, and in the Intel Power Gadget it looked like the frequency was locked to the minimum frequency. Didn't really seem like the laptop was running hot, the fans were not spinning up either, but still looks like it was being throttled. Was this caused by Flash, or by the low battery state? The CPU seemed to scale up fine again this morning after I plugged it in.
