The controversy first emerged in late-2016, when it was reported that since a recent iOS update, some iPhone handsets had begun to experience unexpected shutdowns when their battery capacity reached 30%, caused by drops in the battery's terminal voltage below a threshold of around three volts required for operation of the device.

Discharging the battery fully before recharging may be called "deep discharge"; partially discharging then recharging may be called "shallow discharge". A "charge cycle" is not a unit of time; the length of time spent charging or discharging does not affect the number of charge cycles. [1] Each battery is affected differently by charge cycles ...
The Apple Battery Charger is a battery charger which was sold by Apple Inc. and bundled with six AA batteries. It was introduced in July 2010 and marketed as a way to charge Apple's wireless Magic Mouse , Magic Trackpad and Apple Wireless Keyboard . [ 2 ]
Depth of discharge (DoD) is an important parameter appearing in the context of rechargeable battery operation. Two non-identical definitions can be found in commercial and scientific sources. The depth of discharge is defined as: the maximum fraction of a battery's capacity (given in Ah) which is removed from the charged battery on a regular basis.
Capacity loss or capacity fading is a phenomenon observed in rechargeable battery usage where the amount of charge a battery can deliver at the rated voltage decreases with use. [ 1 ] [ 2 ] In 2003 it was reported the typical range of capacity loss in lithium-ion batteries after 500 charging and discharging cycles varied from 12.4% to 24.1% ...
Battery balancing and battery redistribution refer to techniques that improve the available capacity of a battery pack with multiple cells (usually in series) and increase each cell's longevity. [1] A battery balancer or battery regulator is an electrical device in a battery pack that performs battery balancing. [ 2 ]
A power bank is a portable device consisting of a battery, a charger to interface battery with charging power source and an output interface to provide desired output voltage. [10] Power banks are made in various sizes and typically based on lithium-ion batteries. A power bank contains battery cells and a voltage converter circuitry.
The most significant changes to the iPhone 6 and iPhone 6 Plus are its displays; both branded as "Retina HD Display" and "ion-strengthened", the iPhone 6 display is 4.7 inches in size with a 16:9 resolution of 1334x750 (326 ppi, minus one row of pixels), while the iPhone 6 Plus includes a 5.5-inch 1920x1080 display (401 PPI). The displays use a ...
