Oppo is the next far-eastern star on the mobile horizon and the goal is obviously to catch up with Huawei and Xiaomi. Oppo is doing this by trying to push innovations like periscope cameras, in-display fingerprint scanners, and, of course, Super VOOC fast charging in its phones. This technology alone is enough to wow many people and rightfully so. The Oppo Reno4 Pro takes the fast charging game to new levels, offering a full charge of its 4000 mAh battery in just 43 minutes (36 minutes advertised).
