On July 19th, Chinese manufacturer, Xiaomi released its largest phablet, Xiaomi Mi Max 3 which comes with a 6.9-inch display and its powered by a Snapdragon 636 chip. Xiaomi emphasized on the display of this phablet noting that it provides more content area due to its “full-screen” design. However, the display is not the only attractive selling point of this device. It also comes with a huge 5500 mAh battery which is not common amongst “first-class” manufacturers.
This battery supports 18W fast charge which the company claims can give 71% in 60 minutes and it also comes with reverse charging which means that it can act like a power bank for smaller devices. A few days ago, Xiaomi released a video on Weibo which compares the battery performance of the Xiaomi Mi Max 3 with vivo X21, iPhone X, and oppo R15. All devices were fully charged and subjected to one-hour online video playback, one-hour online music playback, one-hour video shooting, WeChat video calling and two hours gaming.
The test results show that when the vivo X21, iPhone X, and oppo R15 were fully exhausted, the Xiaomi Max 3 still has 44% power remaining. The battery mAh of these smartphones are nowhere near that of Xiaomi Mi Max 3. While iPhone X comes with a 2716mAh battery, vivo X21 and oppo R15 sports a 3200mAh and 3450mAh battery respectively. Nevertheless, battery performance is much more than the mAh of the battery.
