Re: Pixel Phonebuff video.
It's more a case of poor ram management or at least aggressive ram management which does affect your daily usage even outside of scenarios as the video demonstrates.
The Pixel in that test under performed and was akin to the Galaxy S6/S6e last year with its very poor ram management, something which a stock device simply should not be having. Indeed the pixel in the video is peforming akin to the Nexus 5X with 2gb ram.
Ive seen videos and ram usage is the same as the Nexus 6P so the Pixel is not utilising more ram and running out, it's actually being closed out / flushed if that video is accurate. Which was same as the aggressive ram issue on the S6 accept here we can't blame TW.
So why ?
Two possible scenarios.
1) Android 7.1 on the pixel still has bugs / chinks that need to fixed
2) The underclocked Snapdragon 821 could point to the fact they are also aggressively killing ram as a way to extend battery life.
We have seen the OP3 do a similar thing where it's 6gb ram on arrival only performed like a 2gb device, and even with the update to fix the issue, the build.prop limited adjustment OP changed to means it still only uses around 3 tops of the 6gb available. (Meaning unless you circumvent the issue and adjust build.prop yourself you will never benefit from 6gb).
Anyway so there are your two scenarios.
1. Buggy software
2. An artificial ram limiter which expunges stored data early in order to preserve battery.
If it's the latter, that would truly suck. A €750 pixel shouldn't perform like a €250 Nexus 5X memory wise.
However I hope it's the former and it's simply buggy software.
Time will tell, what we need is a Pixel Vs Nexus 6P running 7.0 to see a comparison in behaviours.
