Apple marketed its battery charger as environmentally friendly due to a lower standby power draw, although Massachusetts Institute of Technology engineering professor Gerbrand Ceder criticized Apple for shipping peripherals that require disposable batteries, instead of non-removable lithium-ion batteries like many of Apple's competitors.
Universal charger or common charger refers to various projects to standardize the connectors of power supplies, particularly for battery-powered devices. Since the publication of the USB Power Delivery standard in 2012, and the USB-C connector in 2014, USB-C has become a widespread standard for charging mobile phones.

In semiconductor devices, problems in the device package may cause failures due to contamination, mechanical stress of the device, or open or short circuits. Failures most commonly occur near the beginning and near the ending of the lifetime of the parts, resulting in the bathtub curve graph of failure rates.
Apple released two chargers using the MagSafe standard in 2020: the MagSafe Charger, which is a single charging pad for iPhone, and the MagSafe Duo Charger, which is a charging mat with both MagSafe and an Apple Watch charger.
