Keep in mind that for widgets like phones and tablets that they are not always cycling fully on a daily basis. Lithium Ion batteries degrade much faster being deep cycled from 100% to near 0% than if you are only going 80% to 20%, like an order of magnitude longer. Most applications do not ever fuly charge the cells, and shut down before hitting zero to trade off a little capacity for vastly longer useful lifetimes.
