The Nokia Lumia 800 was sleek enough to convert us to Windows Phone, but like a delicious chocolate cake laced with monkey spit, something just didn't seem right. That thing was battery life. On release, the Lumia 800 barely made it through 24 hours even with minimal use – that is, until the long-awaited Nokia update was rolled out over the past two weeks.
If you own the Lumia 800, the update should be ready and waiting according to Nokia. Your phone should automatically tell you when the update's available, but you'll need to hook it up to your computer and use the Zune software to perform the update. If you haven't had this message, go to Settings > Phone Update to double-check. If you still can't see the update you should contact Nokia, as it may be a problem with your handset.
We upgraded our Lumia 800 last week and the difference we've personally seen is remarkable. After 24 hours of moderate use – plenty of texting, emailing, web browsing and the occasional short call – we still have an average of 50% charge remaining. Like Martin O'Neill replacing the floundering Steve Bruce, the change has been outstanding*.
The main improvement has been to standby mode - prior to the update, some background tasks continued to churn even when the phone was locked. We'd go to bed with a decent amount of power remaining, and wake up to an almost dead mobile. This problem has been successfully resolved.
However, it seems that not everyone who installed the update is so chuffed. We've seen reports on Twitter and on Nokia's forums that some users have experienced worse battery life since updating, although it's a comparably small number so far.
We contacted Nokia, who said it hasn't heard of these issues and to contact them if you're experiencing problems:
"If our users have concerns about their battery capacity they should contact Nokia Care (phone numbers and locations can be found via www.nokia.com/support) who will work to resolve any issue. It is worth mentioning that people should use the original Nokia Fast USB Charger AC-16 or the Nokia Charging and Data Cable CA-185CD that came with their Lumia 800s as they are specifically designed to charge the Lumia 800 as efficiently as possible. Only a charger with an output of 1000mA will fully charge your Lumia 800 battery."
In the meantime, if you own a Nokia Lumia 800 please let us know if you've installed the update, and what difference you've noticed. You can comment below, or on our Facebook page.
