Efficiency for the circuit is the product of U1 efficiency and U2 efficiency, and varies with input voltage and load current. You might think that efficiency can be improved by connecting one end of L2 directly to the single-cell input, but not so. Instead, to accommodate the variation of input to output voltage, you must choose an inductor that achieves the highest efficiency over the full range of input voltages. With L2 connected to the input, the best efficiency is obtained for an L2 value of 6.1H. Efficiencies for the two configurations are actually similar, with the cascaded configuration only 1% higher. The cascaded version also produces a smaller and more predictable output ripple over the full range of input voltages.

Do not use incompatible cell phone batteries and chargers. Some Web sites and second-hand dealers, not associated with reputable manufacturers and carriers, might be selling incompatible or even counterfeit batteries and chargers. Consumers should purchase manufacturer or carrier recommended products and accessories. If unsure about whether a replacement battery or charger is compatible, contact the manufacturer of the battery or charger.
Do not permit a battery out of the phone to come in contact with metal objects, such as coins, keys or jewelry. Do not crush, puncture or put a high degree of pressure on the battery as this can cause an internal short-circuit, resulting in overheating.
Avoid dropping the cell phone. Dropping it, especially on a hard surface, can potentially cause damage to the phone and battery. If you suspect damage to the phone or battery, take it to a service center for inspection. Do not place the phone in areas that may get very hot, such as on or near a cooking surface, cooking appliance, iron, or radiator.
