Today, smartphones are way more than just phones. They are practically a complete pocket multi-purpose computer with software capable of performing even the most difficult tasks with varying effectiveness. Unfortunately, even the most capacious battery can drain quite fast and needs frequent, if not daily, recharging. Qualcomm has a way to alleviate that — it’s called Quick Charge 4+.
Quick Charge 4+ is the successor to last year’s Quick Charge 4. You may find this move surprising because you certainly haven’t seen devices supporting such standard.
Qualcomm Quick Charge 4+ has three major improvements compared to its predecessor. The first one is Dual charge, which divides the charge current across two management Integrated Circuits. According to Qualcomm this move should reduce the charge time by 15 percent and lower temperatures by 3°C. Qualcomm says that that thanks to QC4+, a device can go from empty to 50 percent in just 15 minutes.
The second new feature is called Intelligent Thermal Balancing. Currently, some phones get hot at certain points during charging. This new feature moves the electricity through the coolest path and eliminates these hot spots. QC4+ is also monitoring the device case and connector temperature to avoid overheating.
Every accessory labeled with 4+ logo will be compatible with previous versions of Quick Charge. If you are planning to get a new charger or power bank, you don’t need to worry that your QC 2.0 or 3.0 device will not be compatible. Qualcomm says that the first device with QC 4+ will be ZTE Nubia Z17. The Nubia Z17 sports the Qualcomm Snapdragon 835 as its CPU.
