If you have been following the Chinese phone scene in recent years, you would have seen the ineluctable arms race. It seems like there's a new champion every few months, and high-wattage chargers keep increasing the time it takes to fill a phone battery.
This month, Xiaomi is launching its major push to deliver "HyperCharge" technology to a worldwide public. The next Xiaomi 11T Pro comes with a 120W loader, representing a significant power boost for the global flagship Mi 11, which utilizes a 55W loader that can reach you in 45 minutes at 100%. Xiaomi has not yet disclosed estimated 11T Pro charge timings, although China-only Mi 10 Ultra last year has also featured a 120W loader that took just 23 minutes to complete.
A frequent response to that kind of rapid charger is that it certainly has a detrimental effect on the battery's life or that security problems or both are involved. So I spoke to Daniel Desjarlais, the international communications manager and global Xiaomi spokesman, on the rapidly changing technological efforts of the business and what the outside of China people can anticipate with the 11T Pro.
How does it operate first off? "It's like two distinct gas inlets in your vehicle and two separate tanks," Desjarlais explains of the dual-cell architecture of Xiaomi's battery, which's comparable to how other high-energy quick-charge options operate. "You may now fill two at the same time, instead of filling at a particular sluggish pace on one side. This is done at the side of the phone, the cargo produces 120 watts and, rather than pushing the maximum five volts, it is divided into two, three, four channels by a single channel. This enables us to raise everything – all is done at 20 amperes."
Desjarlais explained in great detail what happens to the technology in the battery and how Xiaomi temperature monitoring systems operate to keep the maximum charging speed at each stage in the cycle. I am honestly not prepared as a non-engineer to comment here on the electrical architecture. I can comment on phone design and customer expectations, and I know many people are worried about the compromises with these high-speed charging solutions.
On the lifespan issue, Desjarlais argues that you may anticipate endurance on a more traditional basis. "We've really, really, very extensively tested this," he adds. "All in all, at this charge level with the batteries that we have tested with, you will still have 80 percent battery health after 800 charging cycles. Now, 20 percent may be like 'oh wow, I lose 20 percent,' but essentially all charging technology is common. 800 cycles, it's going to take approximately two years for most individuals. So that's very strong."
Apple – a business that has been struggling with long-lasting battery performance while providing slower charging technology than most of its rivals – promises consumers that a lithium-ion battery would maintain "up to 80 percent of its original capacity at a total of 500 charge cycles." If Xiaomi's test data are correct, a telephone like the 11T Pro should not be particularly short-lived, even if its owner only ever uses a fast charger.
When I question if utilizing slower charges will further enhance the battery's health, Desjarlais replies that the two are rather small. Of course, if you charge overnight and use the fast charger for more hasty circumstances, the optimum location would be yes." But Xiaomi was tested on the assumption that you can obtain excellent battery health if you always utilize rapid charging.
Concerning safety, Desjarlais said that the testing was very comprehensive and involved third parties with 34 specific battery protection measures. "This is generally part of why this technology is now being developed on global markets," he adds. "We wanted to make sure we fulfilled all the rules, but it was unbelievably safe for everyone as well."
Nevertheless, I pondered about these possible compromises. Are there any disadvantages to such a charging system? Can a phone with a more traditional charge be slimmer or, for example, contain a larger battery? There is no detrimental effect, according to Desjarlais. However, the actual charger is a little bigger than the typical telephone pack, and it will naturally get more power (albeit for shorter periods.)
Xiaomi believes its high-speed technology is here to stay, and space may yet be improved. Earlier this year, the firm, for example, showed a 200W prototype that filled a battery of 4000m Ah in 8 minutes, but Desjarlais would only comment, "if it arrives in a commercial product, it's something that you would have to wait and see." He gave much the same reply on the true wireless Air Charge teaser from Xiaomi, stating, "This is a great idea and one we are examining."
Safety and efficient functioning should obviously be the least you expect from any particular telephone feature. The issue with quick charging is whether consumers in Xiaomi's worldwide markets would consider it a point of sale. "For us, I believe the main objective here is many people who see quick charging as an alien function," Desjarlais said. "There are also a lot of individuals out there that have a great added value. You don't truly know how wonderful it is for your everyday life until you have to hurry out the door in 5 minutes and your phone doesn't pay."
Xiaomi's 11T Pro and 11T Series worldwide launch event will take place next Wednesday, 15 September.
