Should i install ios 6.0.1 on my new iphone 5?

I just got my iphone 5 and it's been draining battery quicker than i thought it would. My phone tells me i need an update but i heard that installing 6.0.1 messes up your phone, anyone know anything about this? I lost 2% in 2 minutes surfing the web on Wi-Fi

No do not download it it also ruins your battery lie by 15 percent
