The Oppo A6s Pro is powered by the same Helio G100 Max chipset as the A6 Pro. The chipset is cooled by a vapor chamber to prevent throttling. Inside is a 7,000mAh battery with 80W SuperVOOC charging.
The Honor X6d is very similar to the Play 60A - the main difference is the upgraded 50MP f/2.0 camera (the 60A only has a 13MP f/2.2 camera). It's still the only lens on the back and it still tops out at 1080p @ 30fps video recording, but it is an upgrade. The 5MP f/2.2 selfie camera is the same.
