Quick Charge is a Qual­comm tech­nol­ogy that en­ables smart­phones and tablets to charge faster. In 2012, there were over 70 de­vices that came with Quick Charge 1.0; and last year, Qual­comm re­leased Quick Charge 2.0 as part of the power man­age­ment in­te­grated cir­cuit in the com­pany’s Snap­dragon 800 pro­ces­sors. In a nut­shell, Quick Charge 2.0 de­vices can charge up to 75% faster than those with­out, or 40% faster than Quick Charge 1.0 de­vices. A com­pat­i­ble wall charger is also needed.

How­ever, note that not all Snap­dragon 800 de­vices sup­port Quick Charge 2.0. For ex­am­ple, the LG G2 does, but the Nexus 5 doesn’t be­cause it uses an­other com­pany’s bat­tery charg­ing IC.
