Appalling experience with MacBook Pro 2016

I switched to a MacBook Pro with Touchbar, top-of-the-line configuration (2.9 Ghz, Radeon 4 Gb, 1 Tb disk) from a late 2014 model.

My previous Macs were working flawlessly. I did a clean install (no migration) on this one, and did not add any software that wasn't in the previous one. Yet am encountering quite a few issues:

- Need to restart at least 2 times a day. Sometimes it just hangs when opening.

- Sometimes no sound at all. Restart again

- Pinch-to-zoom stops working, about once every 2 days. Restart!

- Battery life is dreadful. When I had 4 hours with the previous Mac, this one gives me 2 1/2 h top, and it's brand new...

- I'm rendering 3d with Blender. With the GPU, the rendering is very, very slow. It's ok with the CPU, but... even with the Apple charger, the computer consumes so much energy the Apple power adapter can't keep up! So I have about 2 hours of runtime, then it shuts down.

- When connecting an external monitor through USB-C then HDMI, it doesn't recall the settings and the monitor stays blank. I created an Applescript to automate switching resolution, since I plug / unplug my Mac about 5 times a day, but still.

On a positive note, the space gray color looks nice, and the touch ID works flawlessly.

Switching back to my previous computer is not an option, since I don't have it anymore. Any suggestion???
