I finally updated my N9 to the new FW but got very disappointed with the battery life afterwards. It was draining like no tomorrow. After doing some reading on the excessive battery drainage from others with similar problem, the solution that may work to solve the issue is to restore the phone. I just did not do the restore but I cleared it to start off fresh. After doing so, the battery issue may have been sold but I cannot download any apps from the store. I get this notice: "Dependency notice...To complete installation, a conflicting application needs to be uninstalled....accept or cancel".......of course I click 'accept' but nothing happens....I've cleared the phone twice already and still getting the same result. Help? Any suggestion is appreciated. Thanks.
