Comment:

 I'm seeing the same sudden shutoff with candidate-762, Q2E18 on a G1G1
 XO-1.  Some warning of impending shutoff would be great.

 My other laptops start blinking the battery status LED at ~10% SOC, go to
 sleep at ~6% SOC and then hibernate at ~4% SOC. A software-only fix might
 be to copy the battery icon from the frame into an always visible state
 (an overlay similar to the "full-screen" icon in the Browse activity) when
 the SOC gets low.
