I'd say its still superior to N9, at least on some use cases. Power consumption seems to bee quite constant regardless of what I'm doing with it. Last couple of days my Jolla has been online (3G and WiFi at the evenings), Skype online for day and some phone calls and some Internet surfing. With similar usage N9 would have run out of power before 19.00. So, even very unoptimized Jolla seems to beat N9 on that regard.

Also, reception seems to be better on Jolla, I talked with my friend while driving back home today, usually N9 (and every other phone I have used also) would drop a call at least once on that route. Jolla didn't have any problems on the same route. So, I'd say we have pretty solid smartphone, although there is much work to do with it.
