 Maybe I'm off track but I'd suggest having no 1% battery events at all.

 Instead the host should send a threshold for the capacity to the EC.
 If capacity falls below that threshold the XO is woken up.
 When woken up the XO transmitts a new threshold to the EC.

 Thus the XO can decide that a drop from 98% to 96% does not matter
 whereas a drop from 9% to 8% (or 8.4%) does.
 (Preferrably a raw value is transmitted. If raw instead
 of cooked values are used then the EC does not have
 to have an idea about current sense resistors or capacities
 (kernel probably does not want to know either:))
