Linear chargers are widely used for single-cell rechargeable LiIon batteries in handheld applications due to their simplicity, low cost, and small size. Despite all the advantages of linear charging typology, it does have its Achilles' heel: high thermal dissipation. The relatively low processing power, small monochrome displays, and limited functionality found in early handheld devices allowed the use of low-capacity battery cells that could be rapidly charged at lower currents, thus effectively sidestepping the major thermal flaw of the linear charging topology.
