Qualcomm presented its new fast charging technology: Quick Charge 5. Tempting promises for a full charge in just 15 minutes.
While lithium battery technologies stagnate, fast-charging technologies soar year after year. While we were still dreaming of 30 W chargers only a few years ago, now manufacturers are starting to display 3-digit power. After the BBK Electronics group – Oppo and Realme -, it is Qualcomm’s turn to announce its Quick Charge 5 with a power of 100 W.
“The fastest recharge in the world”
Although Oppo and Realme offer 125W charging – which is 25W more – Qualcomm prides itself on offering the fastest charging in the world today. And for good reason: with Quick Charge 5, it only takes 5 minutes to recover 50% of energy on a 4500 mAh battery and 15 minutes for a full charge. By way of comparison, BBK Electronics proposes for its part to completely replenish a 4000 mAh accumulator in 20 minutes.
The difference is played out among other things on the management of heating, Oppo having announced that its charger is able to fill a 4000 mAh battery in just 10 minutes if we cut all the thermal safeguards. However, Qualcomm is not left out either and promises three levels of protection to avoid any danger when recharging, both in the power supply and the phone using dedicated controllers. Of course, the heating will also depend on the integration of each manufacturer …
Because this is the strength of Qualcomm: the San Diego company is setting up technologies to sell them to different manufacturers. This standard is therefore available from several brands – a detail that will be important when manufacturers stop providing the charger in the box of smartphones -, but also with different standards and previous generations.
In addition to the backward compatibility of the fast charge with the Quick Charge 2 to 4+, the Quick Charge 5 is also compatible with USB-PD devices (many computers, the Nintendo Switch….), Or even the latest iPhone. The charger takes care of itself to recognize the device and adapt the current delivered to offer the fastest possible charge.
Wireless charging compatible
In addition to offering very fast wired charging, Quick Charge 5 technology is also wireless compatible. However, it remains to be seen how manufacturers will adapt this technology to their smartphones.
Qualcomm nevertheless seems to have secured its back on many points with 8 levels of voltage protection, 3 for current, 3 for temperature and many elements allowing to analyze the load and the target device in real time in order to adapt charging capacities from 3.3 to 20 V or from 3 to 5 A. Just like the Quick Charge 4 – or the proposals of BBK -, the Quick Charge 5 is based on a technology “dual charge», Here improved, managing two cells at the same time in order to send twice as much voltage – and therefore to recharge the smartphone twice as quickly.
As always, in order to protect the battery, charging is done in stages. It is faster when the accumulator is empty and slows down as it nears completion. Qualcomm thus promises a battery life similar to current times.
Xiaomi on the front line
Qualcomm is only the supplier of the Quick Charge 5 and it is now up to manufacturers to integrate it into their products. The first smartphones to be equipped with it will arrive by the end of 2020. The first to draw should be Xiaomi, possibly on the Mi 10 Pro +, or why not a new Mi Mix.
In addition, the American company announces that the integration of the Quick Charge 5 should not induce a price increase. Good news given the four-figure prices of the best smartphones of the moment …
