Nokia acknowledges the Battery issue, to fix Camera and Audio with subsequent updates
Nokia recently released a fix for the concerns over the battery performance on the Lumia 800 device.
First of all, the primary target of the latest Lumia 800 update (1600.2483.8106.11500) was to enhance standby time as well as to bring an improvement to the issue reported by some customers in December, that their phone wasn’t able to access the full battery charge capacity correctly. We can confirm that we have successfully tested that those improvements are working.
Nokia also mentioned about addressing Audio and Camera settings by issuing updates in the future.
Additionally, we’ve noted your concerns regarding audio and camera settings and are going to address those in a series of future updates, ie. these will not be included in this specific update.
Do check if you are on the latest version by going to Settings -> System -> About and then tap on “More Information”. Your Lumia 800 should be on 1600.2483.8106.11500.
They also request users not to use the Diagnostic App designed for Internal testing purposes and instead use the OS notifications on the Battery status.
Also always use the original Nokia Fast USB Charger AC-16 or the Nokia Charging and Data Cable CA-185CD that came with your Lumia 800, 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. If you have several Nokia chargers at home, just check the respective labels or plastic parts as the product name is mentioned there.
Last but not least, the Diagnostic App was designed for internal testing purposes. In general, your battery is fine as long as the full charge capacity is more than 1000mAh. For the future, if you are checking your battery life, more useful information on the Battery status can be found by focusing on Settings>System>Battery saver. It will tell you both your remaining battery life in percent as well as the estimated time remaining, plus the time since you last charged your phone (as soon as you have disconnected your phone from your charger). If you have concerns about your battery capacity, please contact Nokia Care (phone numbers and locations can be found via www.nokia.com/support).”
Do let us know if you are on the latest battery fix and your views on that.
