How fast self-discharge in a battery occurs is dependent on the type of battery, state of charge, charging current, ambient temperature and other factors. [2] Primary batteries are not designed for recharging between manufacturing and use, and thus to be practical they must have much lower self-discharge rates than older types of secondary cells.
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 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.
Modern dash cams require continuous power to capture and store footage on the go, though many have small built-in batteries or capacitors that take over when an emergency occurs (like when an ...
