The iPhone is a line of touchscreen-based cell phones planned and promoted by Apple Inc. All ages of the iPhone use Apple’s iOS versatile working framework programming. The original iPhone discharged on June 29, 2007, and they have discharged different new equipment cycles with new iOS discharges since.
The iPhone features an internal rechargeable lithium-ion battery. Like an iPod, but unlike most other mobile phones at the time of its launch, the battery is not user-replaceable. The iPhone can be charged when connected to a computer for syncing across the included USB to dock connector cable, similar to charging an iPod. Alternatively, an USB to AC adapter (or “wall charger”, also included) can connect to the cable to charge directly from an AC outlet. Some models of the iPhone support wireless charging.
