A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.
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.

An 18650 battery [1] or 1865 cell [2] is a cylindrical lithium-ion battery common in electronic devices. The batteries measure 18 mm (0.71 in) in diameter by 65 mm (2.56 in) in length, giving them the name 18650. [3] The battery comes in many nominal voltages depending on the specific chemistry used.
The top and side of an iPhone 5S, externally identical to the SE (2016).From left to right, sides: wake/sleep button, silence switch, volume up, and volume down. The touchscreen on the iPhone has increased in size several times over the years, from 3.5 inches on the original iPhone to iPhone 4S, to the current 6.1 and 6.7 inches on the iPhone 14 and 14 Pro series.
