Pls. Anyone in here that can help? I bought a new Nokia lumia 800 with OS 7.5 on the 27th Feb,2013 which I upgraded to the latest OS which is 7.8. The phone was successfully updated and everything works fine except that the battery drains off so quick. Checked online to see if anyone or people who have upgraded have the same issue of battery draining on their phone and it seems it affected all that did the upgrade. Called the Nokia care point to lodge the complaint and to ask if I could downgrade to the previous OS but was told that couldn't be done. All I want to know is that is there any way out of this problem. I shall be glad to have a response. Thanks

Was there any change on your usage? I would suggest to give your phone a couple of charge/discharge cycles more and then observe if there's any progress on the battery life.

Also, one of our friends here made an article Battery life tips for Lumia family Windows Phone devices. You may want to check it here: http://discussions.nokia.com/t5/Pool-of-Knowledge/Battery-life-tips-for-Lumia-family-Windows-Phone-d...

If above wouldn't help, you can check the link provided below for troubleshooting steps: http://support.microsoft.com/kb/2606900

If you've done all the troubleshooting steps provided on the link above, you may consider sending the phone to a repair facility for assessment. You can go here to select the support website of your country for any repair inquiry/instructions: http://www.nokia.com/global/support/locations/

How did you determine it is draining faster than it should?

What would you consider faster?

Have you search for and read the many, many posts here that explain some of the possible reasons of what you experience and what to do about it?
