A new 100W charging technology being built by Xiaomi, dubbed “Super Charge Turbo," won’t be appearing any time soon based on a recent leak posted to Twitter by tipster Sudhanshu Ambhore. No attribution for the information is provided but the news is in opposition to some expectations that it would be released in 2019. The tweet simply states that Super Charge Turbo won't be arriving this year.
What is 100W Super Charge Turbo?
100W Super Charge Turbo is expected to be exactly what it sounds like. Tipped off by Xiaomi co-founder Lin Bin via Chinese social media site Weibo in late March, it's a charging protocol that ensures safe device charging at 100-watts. The technology was demoed by Lin Bin in media shared alongside the social network post comparing 100W charging to a 50W fast charging situation on an OPPO handset.
The 100W charging protocol was obviously showcased performing much better but the touted results were still extraordinary. The unspecified OPPO gadget was shown to charge up to 65-percent of its 3,700mAh capacity battery in around seventeen minutes. As is the case with any fast charger, presumably that would have slowed down considerably the closer the number became to 100-percent, resulting in an extended wait to a fully charged status.
Conversely, the Xiaomi gadget -- with a larger 4,000mAh capacity battery -- was shown fully charged.
OPPO's technology is considered by many to be at the top of its charging game, pushing the boundaries via the clever use of two separate power cells that charge up simultaneously at 50W. It's not immediately clear whether or not Xiaomi's feature will use a similar approach but powering up an additional 300mAh in nearly half the time is still an impressive feat.
By contrast to other new fast-charging protocols, Huawei's newest 40W "SuperCharge" can be found in its Huawei P30 and P30 Pro. The larger of those handsets' 4,200mAh battery can be charged up to 70-percent in around 30-minutes and there's even a new power bank made by Huawei to show that capability off. A step forward to 100W, if accomplished safely without long-term damage to the battery or batteries, would be a game changer in lieu of new tech allowing for higher-capacity batteries meeting current size restraints.
No surprises here
Given the enormous leap in charging rates and inherent dangers with modern batteries overheating, it isn't necessarily surprising that 100W charging would be a long way off. Indications that might be the case were also found in the initial preview of the Super Charge Turbo feature.
To begin with, battery capacity increases simply aren't feasible if a company wants to maintain a sleek and slim appearance and the appeal that goes with that. Gadgets that go that route are typically labeled bulky, unwieldy, or outright ugly across the industry, leaving OEMs that do focus on battery size relegated to the heavily ruggedized or specialized segments of the market.
That leaves manufacturers with a choice between just a few technological advancements and integration of a combination of those in more expensive flagships. In effect, device makers are forced to choose to make their charging protocol faster too offset the wait between charges or to improve optimizations. That's true whether wireless or wired charging is involved, although wireless charging remains the much slower -- if more convenient -- option.
