From zero to TÜV hero: How the HUAWEI Mate 10 Series significantly improved battery technology

As the two largest, most profitable smartphone makers in the world can't shake off battery management issues, Huawei has spotted an opportunity and seized it with two hands. The company left nothing to chance, and went to the most rigorous third-party certification system - Germany's TÜV Rheinland - to ensure a fresh and demanding set of eyes before launching the phones with the best battery life in its class, the HUAWEI Mate 10 and HUAWEI Mate 10 Pro.

TÜV Safety Certified

Not only does the HUAWEI Mate 10 Series offer the longest endurance on a full battery, but also the fastest charging time relative to its battery size. This is why Huawei had to make sure battery safety lived up to the same high expectations. So, it turned to the renowned TÜV Rheinland labs to submit its HUAWEI SuperCharge tech for the mark of "the first time an end-to-end fast-charging technology has successfully completed the rigorous tests set forth by the world-renowned safety experts," as the TÜV presser puts it.

Germany’s strict insurance standards and tradition of engineering excellence was the driving force behind Huawei’s decision to test itself against the stringent standards of the TÜV Rheinland certification body. The company let them test the battery circuitry, cables, chargers, and anything involved in its adaptive power management that would help to prevent a thermal runaway, or battery degradation.

The TÜV specialists rolled up their sleeves, and went to town on the new HUAWEI Mate 10 Series, plugging in cables from different manufacturers more than 10,000 times, subjecting the HUAWEI SuperCharge accessories to extreme temperatures in both directions, and measuring every step of the way - from the wall charger, through the IC circuitry inside the phone, to the battery packs themselves - for deviations that may lead to thermal runaway or sub-par charging performance that would clash with Huawei's claims for ultrafast charging.

Needless to say, Huawei's newly-minted AI processor is involved in battery management as well, as it controls the phones' processers, and how they interact with the state-of-the-art battery packs inside. 

What’s more, the AI uses machine learning for continuous back and forth conversation between the device and the charger, supervising each second of the cycle. It constantly adjusts the voltage and current of the stock 4.5V/5A or third-party chargers to curb their enthusiasm if needed, in order to keep things cool and electron-friendly along the whole chain of command.

What can we say, our own test results confirmed that the first end-to-end fast-charging technology stamped by the TÜV Rheinland labs is not only secure but also does what it says on the tin. If there is a safest way to mark 12+ hours of screen-on time in our grueling battery benchmark, and fill a 4,000 mAh unit for exactly as long as it takes the competition to fully charge a 3,300 mAh battery, Huawei certainly seems to have found it.
