The Lumia 800, much like the Galaxy Nexus, has had a bit of a bumpy ride in its first few days on sale. A seven-page thread on the Nokia Support forum details battery life issues that many have had with the new Windows Phone handset, which has prompted Nokia into action. The company has today announced it'll deliver two software updates, one in early December and one in early January, both of which will aim to improve power efficiency and battery life. Nokia's statement in full:

"A software update in early December will include improvements to power efficiency, while a second update in early January introduces further enhancements to battery life and battery charging. Both are planned updates and will be made available via Zune."

We haven't had any such problems on our Lumia 800 review devices, leading us to believe that the issue is not universal to all handsets. Nokia's UK team confirmed to us that the statements made on the company's support forum align with its software plans, though no further information has been forthcoming about the cause of the battery life shortcoming.
