I bought a new XPS 13 9315 from dell canada online store. I started using it from yesterday. 

Sadly I'm facing some serious issues now! And it's frustrating.

1. Random shut down: First it shuts down randomly. Then takes long time to boot. Finally takes me to BIOS setup page. It happened five times already. (All the required drivers are installed and updated.)

2. Battery llife is not as good as promised. I am supposed to get 8 hours back up on normal browsing and content watching. But I'm getting only about 5 hours battery backup on normal usage. Performance mode is set on balanced.
