If you’re experiencing poor battery life for the Nokia Lumia 800, a firmware update releasing on January 18th will fix the problem. The current issue on certain devices is that the phone can only see less than 1000mAh battery capacity instead of the full 1500mAh. The date comes from memo received by 3 Italy. Customers who do not want to wait can immediately get a replacement.
