"Nokia has launched the long awaited-software update for the Lumia 800 smartphone that it hopes will address the problems of rapid battery drain on the handset. In a post on the Nokia Conversations blog, the Finnish firm said that the patch, the third update for the Lumia 800 since it was released last year, has now started a phased rollout to all customers. The update is available now in the UK, although it is still awaiting approval from a number of mobile operators, including Orange and O2. Check here to see if you can access the patch.  Users need to connect their Windows Phone to Zune on the PC, or Windows Phone 7 connection on the Mac to download the update to their handset.  Nokia blogger Dinesh said that the Finnish firm has heard the feedback from some users of poor battery performance in the Lumia 800 - Nokia&amp;#039;s first device running Microsoft&amp;#039;s Windows Phone operating system.  He added that testing of the update - which was not originally scheduled to roll out until late April - has indicated that it will address these issues. &amp;quot;We put the software through rigorous tests, and what came out was an update that shows significant improvements in battery life, whether it&amp;#039;s for talk time in 3G networks, browsing over Wi-Fi, music playback, or simply, the overall usage time,&amp;quot; he wrote.  &amp;quot;Our internal testing also showed that for smartphones with similar battery capacities (the Lumia 800 sports a 1450mAh battery), the Lumia 800 was now among the top performers in battery life for the key measures that we concentrated on.&amp;quot; Dinesh continued: &amp;quot;Since I updated my phone, my personal experience - on average these last two weeks - has been between 25 to 30 hours of battery life with my daily usage pattern: numerous phone calls and text messages, browsing, push email on three mail accounts, some music to and from work, some GPS (Drive and Maps) - and with the phone in flight mode for about five hours when I sleep. I must admit, though, I can&amp;#039;t claim to be a power user in any area, but I&amp;#039;m no lightweight either.&amp;quot; Alongside the battery improvements, Nokia said that the update also brings extra bass to the audio for better voice quality, along with new features to Nokia Music. The Lumia 800&amp;#039;s soft keys will now illuminate at all brightness settings. Nokia said that the firm is looking at bringing Wi-Fi tethering to the handset following requests from users, but did not indicate when this would be delivered.
