Adapating a single cell Li-ion battery voltage to 3.3V low power

Assuming the quiescent current is low, the efficiency can be simplified to Vout/Vin. The average Vin for a lithium ion battery is 3.7V. 3.3/3.7 = 89%. So a low Iq LDO can achieve 89% average efficiency. Even if you use a 3V LDO, the average efficiency is still 81%. It is doubtful that using a buck will be worthwile even if VCC is 3V.
