Your Smartphone Battery, Explained
Li-ion batteries primarily degrade over charge cycles—according to Apple, an iPhone retains up to 80 percent of its original capacity after 500 complete cycles (from 100 to zero percent charge). After that, the battery meter would still read 100% after a full charge—but it would only last 80 percent as long as it did when you first got it.
