The State of JavaScript on Android in 2015 is... poor

For those that are not familiar with why Apple devices show higher performance and why Android device manufacturers appear to be playing catch-up here is a nice video with a little bit of history:


For point of reference I ran some of the benchmarks on my OnePlus 2 (ONE A2003) an August 2015 Qualcomm Snapdragon 810 phone - the same processor as the Nexus 6P mentioned above.
This was a new phone when this thread was started back in 2015, now updated the phone running on a custom Lineage OS build (Android 7.1.2). In a months time a replacement phone will come and I’ll reset the device to whatever the latest manufacturer OS is and run these numbers again.

Browser version “render complex list”, 2.11 Speedometer
Chrome 61 (Stable) 152.27ms 27.2 (±2.4)
Chrome 62 (Beta) 179.04ms 25.4 (±1.4)
Chrome 63 (Canary) 190.00ms 23.7 (±1.7)

Allowing the phone to “cool” between benchmark runs - these are pretty repeatable numbers.

Hopefully this doesn’t indicate that Chrome is slipping backwards any when Chrome 63 finally reaches the general public.
