The saga of the Nokia Lumia 800's battery life may be drawing to a close. Despite Nokia claiming to have solved the issue a couple of months ago, we recently came across an update pushed out to users in Singapore that reportedly "tripled" the handset's endurance. That same update, version 1600.2487.8107.12070, has been announced for a global release today with "significant improvements" to power management. It's going to be pushed out in four "batches" over the next few weeks due to the varying demands of carrier testing in different countries, and also includes tweaks to the device's audio performance.

The Nokia employee who posted details of the update says that he's been getting around 25-30 hours of battery life with a fairly active usage pattern since updating a couple of weeks ago. However, he also says that he was putting the phone into flight mode at night, which means we don't have any new information on how the update will affect idle discharge — one of the main problems reported with the Lumia 800's battery. We'll be sure to let you know our findings once we're able to update for ourselves, though we didn't see any major issues with our review units.
