The Android Oreo beta update software has introduced fast charging to the Xiaomi Mi A1 according to a recent report, noting that the software, once installed, led to this feature being discovered along with all of the more noticeable changes that came along with it. Xiaomi devices don't usually support the Quick Charge feature that can be utilized due to the use of Qualcomm chipsets, but with the Mi A1 being an Android One device and Xiaomi's first in this particular category, it seems that Xiaomi wanted to make this feature available to the consumers who picked one up, which could have had something to do with the device being representative of what Google envisions for the Android One platform as Google likely wants it supported.
Though not all Mi A1 users may have noticed the faster charging capabilities of the phone, it's reported that while using the Dash Charger that comes with OnePlus devices, the device was able to charge up to 100 percent in a total of 92 minutes. That's one and a half hours compared to the two hours it used to reportedly used to take to get all the way up to a full battery which is a decent improvement in the charge speed even if it isn't by an extremely significant amount like cutting the charge time in half.
Since this is an Oreo beta the software hasn't officially rolled out to all the owners of the Xiaomi Mi A1, meaning that right now, only some users are going to have access to the Oreo software and this new fast charging feature that comes along with it. Xiaomi hasn't mentioned when it plans to push the stable version of the Android Oreo software out to all of the users that have the Mi A1, but the beta has been floating around on user devices for a little while so perhaps it won't be too much longer before Xiaomi sends out the update to more people. In addition to the fast charging feature, the Oreo software should also be coming along with the other software improvements like overall better battery life and improved performance of the software, among other things.
