The battery life reports on the Lumia 800 have been mixed right from the start, with some people getting great longevity while others finding out first hand what poor battery life really means. Turns out its all down to software and Nokia is promising an easy fix via a firmware update in ‘early 2012’. The Lumia 710, thankfully for Nokia, is immune to this problem.
The problem seems to be caused by the phone not being able to access the entire capacity of its battery, similar to what Nokia had said three weeks ago:
We understand that some people have expressed concerns about battery life on the Nokia Lumia 800. Early investigations show that most people are enjoying the full Nokia Lumia experience without any problems and we have not been able to identify a single root cause that would lead to erratic battery behavior at this stage. A software update in early December will make some improvements to power efficiency, while a second update in early January introduces high voltage charging, increasing the Nokia Lumia 800’s battery power from 1300mAh to 1450mAh. These are scheduled improvements and will enhance the overall experience, but are not designed to address any issues that may be occurring with individual products. We recommend that anyone who has concerns contact local Nokia care representatives at their earliest convenience.
It seems they’ve now done some additional testing and released the following statement:
On Monday 12th December some of our customers started to comment in various social media that the preloaded diagnostics tool in some of the Nokia Lumia 800 phones was showing lower battery capacity than expected. We immediately started to investigate these reports and can now confirm that while the battery itself is fine, a software problem on certain variants is limiting the phone’s ability to access the full battery capacity. We want to stress that this issue has not been found to affect the recently introduced Nokia Lumia 710.
The good news is that as this is a software problem it can be easily resolved. The planned software update in early 2012, as well as including many performance enhancements, will also include a fix that will enable the affected phones to access the total battery capacity. For anyone who does not want to wait for the software update, Nokia can arrange for a replacement phone. Anyone who requires any further clarification should contact Nokia Care (Care contact details and locations can be found at www.Nokia.com/support).
Anyone who wants to know if their phone is affected can run the battery status test from the diagnostics tool already installed on their phone. (The tool is designed for service use and only displays approximate values.) Dialling ##634# opens the diagnostics tool. By accepting the disclaimer and then selecting ‘Battery Status’ from the list of options, anyone will be able to see their available battery charge capacity. If your full charge capacity reads less than 1000 mAh then your phone is affected with this specific issue and you may find it is necessary to charge your phone more frequently than normal. Once the software update has been applied, you should experience much better battery life. In the meantime here are some tips on how to increase your battery performanceand you should also make sure you are using the charger that came with the phone, as older chargers may not be as effective at charging the new Nokia Lumia 800.
Meanwhile Nokia India also got in touch with us and have released the following statement.
India impact will be minimal since we just started shipping. Therefore, If a consumer buys a Nokia Lumia 800 today, there is absolutely no impact. Nokia will go the extra mile to delight their consumers especially with a flagship product like Lumia 800.
Following GLOBAL reports of examples where the preloaded Diagnostics tool in the Nokia Lumia 800 was showing lower than expected levels of full battery charge capacity we immediately conducted extensive testing on the devices at a global level.
Following the tests, we can now confirm that while the battery in the devices is fine, in some variants a software problem is preventing the phone from accessing the full battery capacity.
The good news is that as it is a software problem it can be easily resolved and the planned early 2012 software update, as well as including some performance enhancements, will also include a fix that will enable the affected phones to access the total battery capacity. Once this update is applied customers should experience much better battery life.
Anyone customer who needs further clarification is being asked to contact Nokia Care (Care contact details and locations can be found at www.Nokia.com/support)
If you’ve just got your Lumia 800, I suggest you hit ##634# to check if you’re affected. Incase you are, a quick trip to the Nokia Service Center should sort you out.
All in all, since the new units that Nokia ships will have this issue fixed, you can be sure it’ll be problem free if you go buy a Lumia 800 starting today.
