We experienced occasional battery and charging problems when reviewing
the Lumia 800, and it looks like others have had issues too. In fact, it's become a sufficiently (un)popular topic on Nokia's support forums to encourage the company to post up a reply, confirming that two software fixes are in the works. The first will target power efficiency and arrive in early December, while the second will follow in January and hopefully improve charging. Only a minority of users are affected, we're told, so it's lucky for them that they're vocal.
