All Android phones have fast charging built in, but not all standards are created equal. While several brands rely on USB's standard Power Delivery, Chinese manufacturers use their own tech instead, delivering significantly higher charging speeds on their phones.
OPPO's SuperVOOC is the industry leader in this area, with the brand able to push battery charging to as much as 240W. That's an outlier, but on most OnePlus and OPPO phones available today, you'll see 65W and 100W charging as standard, allowing these devices to fully charge their batteries in under 30 minutes.
