Friday, July 13, 2018 [19659005] The batteries of smartphones do not grow, but they can charge faster and faster. Huawei is now apparently on a record track: A new charger from China could again quickly empty empty batteries.
Because the edges of the screen shrink in smartphones, but the case does not grow constantly, even though the battery capacity is not infinite – although many users want durations longer use accommodate compact housings of their flagships. To compensate for this, smartphone companies have been competing for some time for the shortest charging times. With his next high-end smartphone, Huawei could take the lead.
Who is in the lead?
The time it takes to fully charge a battery depends a lot on the charger you are trying to charge. At a snail pace is the USB port of the computer. Charging a power adapter suitable for the power outlet is noticeably faster. And it's even faster when the smartphone's battery and the AC adapter are charging fast. Because even the charging technology supported by the battery is crucial for charging time.
Some manufacturers rely on their own standards – OnePlus for example, which allows extremely short loading times thanks to its Dash-Charge technology. Others use Qualcomm's quick charge QuickCharge standard. The Chinese manufacturer Oppo has recently introduced a new standard, with which you should be able to fully charge a full-size battery with 3730 milliamp hours in just 35 minutes. "Super VOOC" is said to be reserved for the Lamborghini luxury version of the Oppo Find X.
40 watts of power
For consumers, the benefits of this arms race are obvious: shorter charging times mean more flexibility and faster times. Waiting reduced. But to use the new standard, the smartphone must be able to do it. So with Huawei's new Super-Charger, you can not fill a smartphone quickly. Devices that do not support the standard load more slowly. And the competition also has another drawback: if each manufacturer develops its own standard, each smartphone needs its own charger, which means more electronic waste. Thus, the industry agreement on a common connector standard (first microUSB and now USB-C) is at least partially canceled again.
