At present, the fast charging technology used by mainstream smartphones is more due to the native support of Qualcomm chips. Qualcomm has released the latest fast charging technology Quick Charge 3.0.
What is fast charging?
Fast charging is not a new concept, it is to make your smartphone charge faster than ever. The easiest way to get the device to charge quickly is also the most common way to increase the charging current for maximum charging efficiency. The latest fast charging technology now also supports the battery to charge at a higher voltage for higher power transmission. However, both smartphones and phone chargers must normally be compatible with the same charging voltage and current, otherwise fast charging may encounter several situations:
The first case is, if your phone supports 9V/2V charging, but your charger current is only 1A, the whole charging process will become relatively long; and the other case is, your charger The current is 2A, but your phone only supports 0.7A current for charging, which also causes slow charging;
Quick Charge 3.0
What is the performance of Qualcomm’s Quick Charge 3.0 fast charging technology? According to Qualcomm, a traditional mobile phone can be charged from 0% to 80% in about 35 minutes.
There are also two important points in Qualcomm’s promotion of Quick Charge 3.0. One is faster charging speeds of up to 27% compared to Quick Charge 2.0, reducing power consumption by up to 45%; the second is charging speeds that are 2 times faster than Quick Charge 1.0.
However, we need to pay attention to the fact that Qualcomm does not brag about how fast the charging speed is, and the focus is on “improving charging efficiency.” To this end, Qualcomm has developed a perfect technology called “Intelligent Negotiation for Optimum Voltage” to optimize power output and extend battery life.
Qualcomm Quick Charge 3.0 retains backward compatibility with 2.0 and 1.0. Any previously certified charger can be used to charge the latest phones that support Quick Charge 3.0 and guarantee the best charging efficiency. In addition, Quick Charge 3.0 also supports the USBType-C interface standard for charging.
