BBK Electronics subsidiaries OPPO, realme, and OnePlus are known for being the first ones to bring 65W fast charging to the masses, offering it even on midrange phones. The trio is now looking to make 100W the new normal and deem 65W fast charging the lowest standard in the fast-charge range.
Accordingly, next-year flagships from the OPPO Find series, realme GT series, and OnePlus 10 series will be equipped with 100W super flash charging support along with large batteries (via My Drivers).
This doesn’t come as a surprise considering OPPO had already announced their own 125W super flash charging tech back in July 2020. It was the fastest charging tech at the time, made possible with some significant changes to both the battery arrangement as well as the input end.
First of all, OPPO switched from a 3c cell battery to a 6c one along with upgrading the tab center to multi-tab technology. This has greatly shortened the movement path and reduced the cellular impedance, effectively enabling input of 12.5A current while also reducing heat generation.
And on the input end, OPPO’s 125W charging tech uses ‘three parallel charge pumps’ that convert the total of 20V 6.25A current from the charger into 10V 12.5A. This means that each pump only pushes 42W of power into the battery which significantly reduces the load and prevents overheating caused by high current.
But of course, all of the charging tech breakthroughs are rendered unusable if they’re considered unsafe. OPPO has thus taken appropriate safety measures, packing a total of 10 sensors for monitoring temperature changes on the mobile phone and the closed-loop link of the charger. These sensors aid the phone in adjusting voltage and current in real-time to control heating.
The 125W charging tech from OPPO is likely to make its large-scale debut next year.
