100W+ fast charging seems to be a trend these days, as more and more OEMs are getting ready to announce it. iQOO actually did that today, it announced its 120W fast charging via Weibo, and iQOO’s announcement really managed to attract attention.

Do note that iQOO is a company under the BBK Electronics umbrella, same as OPPO, Vivo, OnePlus, and Realme. So, chances are that this is the same technology that OPPO is getting ready to announce.

OPPO teased its 125W fast charging technology earlier today. The company said that it will announce it on July 15, which is in only two days. Realme is also tipped to announce something similar later this month.


iQOO’s 120W fast charging can fully recharge a 4,000mAh battery in no time

In any case, iQOO’s 120W fast charging technology is called ‘FlashCharge’. That tech can fully recharge a 4,000mAh battery in only 15 minutes. So, you can basically go take a shower and have your phone fully charge, from 0-percent.

This is obviously based on OPPO’s fast charging technology, and that’s not surprising. This charging pushes 20V x 6A for a total of 120W of power to supported devices.

This tech actually uses dual-cell battery designs, which is something that most fast charging technologies do, at least those super-fast ones. You’ll need a proprietary charging brick in order to make this happen, of course.


Now, we’ve already said that it can fully recharge a 4,000mAh battery in 15 minutes. What about up to 50-percent? Well, you can get it from 0 to 50-percent in only 5 minutes.

Xiaomi is expected to introduce 100W charging soon

Xiaomi is also expected to announce its fast charging technology soon. The company demoed its 100W charging earlier this year, and it’s expected to become official by the end of 2020.

In comparison to what iQOO announced, Xiaomi’s tech can get you up to 39-percent in 5 minutes. In order to fully recharge a 4,000mAh battery, it’ll take 17 minutes. That’s quite close to what iQOO is offering.


As with all the other super-fast charging technologies, we’re wondering how will this affect battery packs. How much will 100W+ deteriorate the battery over time, and how safe it is.

That is probably the main reason why such super-fast charging technologies are not available to consumers just yet. We’re hoping that OPPO will clear things up on July 15.

Do note that iQOO’s announcement hints that this tech may become available in August. So, we’re closer than ever to this extremely fast charging. This probably means OnePlus will go down that road next year, we’ll see.
