Along with next generation flagship processor, Snapdragon 835, Qualcomm also announced its next version of Quick Charge technology. The fast charging technology has been upgraded from Quick Charge 3.0 to Quick Charge 4 (yeah, without decimals). The new version can give 5 hours of battery life with just a 5-minute charge!
Qualcomm has been one of the best players in implementing the fast charging technology. The company claims it to be best ever Quick Charge version they have built and thanks to previous versions. They have clarified so many things in the Quick Charge 4 announcement today.
Quick Charge 4 : 5 for 5!
Well, Qualcomm’s 5 for 5 means 5mins of charge for 5 or more hours of battery life, let me put all about Quick Charge 4 in 5 pointers.
1. Quicker than 3.0
As per the company claims, Quick Charge 4 is about 20 percent faster than QC 3.0 in terms of the faster charging. It is about 30 percent more battery life efficient compared to the previous version. All that does with 5 degree Celsius less cool than the previous version.
2. Supports both USB Type-C and USB-PD Standards
Qualcomm’s Quick Charge 4 finally falls under one radar supporting both USB Type-C and USB Power Delivery standards. Making it sure of passing the Google test. Though USB-PD works with 3A cable, it would still need 5A specification needed for that support. Thus making every who wants QC4 to use Qualcomm-certified power management ICs to take advantage of it.
3. Wider Access
As Quick Charge 4 supports USB-PD, Qualcomm now happily says, it will now support over 100 mobile devices and over 300 accessory products like wall and car adapters, battery packs and docking stations that also support the technology.
4. Better Thermal Protection
Qualcomm uses in-house baked power management algorithm called INOV (Intelligent Negotiation for Optimum Voltage). It now includes real-time thermal management company which claims to offer “advance charging optimization by automatically determining and selecting the optimal power transfer level for a given thermal condition.”
5. End-to-end Protection
Qualcomm claims for the better protection while taking a dig at latest Samsung Note 7 blasting issue. To handle such situations, Qualcomm has decided to add an extra layer of protection “to help prevent battery overcharging and regulate current throughout every charge cycle”. Sensors and monitors will be put in the chip that will be placed in both smartphones as well as a power adapter.
Apart from all these, the Quick Charge 4 can provide 50 percent charge within 15mins Snapdragon 835 powered device. This is still not equivalent to what MediaTek’s Pump Express 3.0 claims to provide. The Pump Express 3.0 is claimed to charge the battery from 0-70% in 20 Minutes. Well, only time can tell the reality.
As far as the available of the technology, it is expected to arrive along with Snapdragon 835 that is in the first half of 2017.
