The lithium-ion battery is a smartphone component with a relatively short lifespan and is becoming increasingly non-replaceable. Various charging methods can be used to extend the lifespan of lithium-ion batteries. Different charging methods were applied to groups of smartphones programmed to charge and discharge in patterns similar to a typical use case of the smartphone, simulating conventional battery use. The capacity of these batteries were periodically measured, allowing for comparison in degradation between charging methods. Partial charge limiting was found to have a slight benefit in reducing battery degradation, but was vastly outperformed by full charge limiting.
