After the Nokia Lumia 800 went on sale a number of users reported problems with the smartphones battery, as well as some other problems with the devices camera.
Nokia apparently addressed the issue, in a couple of software updates which were released, although it would appear a new firmware for the Lumia 800 has been leaked which comes with some more tweaks to improve the handsets battery life.
Along with the improved battery tweaks, the leaked firmware also has some fixes for the Lumia 800’s camera, along with some new camera modes which include Smart group shot, Panorama, Action and Self Timer modes.
There are no details as yet on when Nokia will release this new firmware for the Lumia 800 as soon as we get some more information we will let you guys know.
