Use lithium battery to make a voltage regulating power supply
Use a buck boost regulator - it would continue to produce 3.3 volts all the way down from probably over 5 volts to possibly 2.5 volts. Obviously you have to ensure that the Lithium battery doesn''t sink too low or it will become damaged but that''s another problem that is solved by using a comparator and a regulator shut-down circuit.

Voltage Regulator For LiPo Batteries
You just need to be familiar with some standard electronic equipment and terms. Even though these devices are widely used, the system works in a similar way for all. The voltage regulator is a part of all power supply systems; even your car has one. Inside the Voltage Regulator, the AC voltage generated is converted into DC voltage.

Introduction. Various resources state that the optimal method of charging a li-ion cell -- such as one found in a mobile phone -- is to charge at a constant current (usually <1C) until a certain voltage threshold is reached, then switch to charging at a constant voltage until the charging current drops to about 0.1C, at which point the battery is fully charged.
