Actually they have done the right thing by going with MTK cause Qualcomm is just **** this year
615 is a joke, 810 is a joke, in fact their whole current lineup is a joke.
Sony's Emerges in The Middle: Is The Price Right
Editorial: Snapdragon Sorrows - Has Qualcomm Begun A Long, Slow Fall From The Top?
"The octacore Snapdragon 615 was purposed for the $250-$400 smartphone segment, powering devices with relatively "premium" features (LTE, high-res cameras, big displays, stylish looks), but built with more modest computing capabilities to save on cost. Such phones include the Oppo R5, HTC Desire 820, Alcatel OneTouch Idol 3, Xiaomi Mi 4i, and Huawei Ascend P8 Lite (US version).
All of these devices are notorious for at least one thing: relatively awful 3D graphics performance. Especially those with 1080p displays, like the Idol 3 or Xiaomi Mi 4i, which struggle to maintain intense 3D games beyond single digit frame rates at times. Most are also saddled with complaints of poor screen-on battery life - something I've experienced with almost every Snapdragon 615 device I've used. The one exception to the poor battery life rule, Alcatel's OneTouch Idol 3, is also by no coincidence the slowest 615 phone I've tested day-to-day, quickly throttling itself at the first sign of high power consumption."
Now its best to go with anyone but Qualcomm till they get their **** together
