On my review on Windows Phone 8.1 for my Lumia 620, I mentioned I have a bad time with battery life although the fresh experience from the update itself is totally worth it. However sometimes it get frustrating when your phone can’t last you for the day and now Microsoft has finally make the new update available to improve battery life and fix a lot of bugs, according to Joe Belfiore, the head of Windows Phone.

Go to setting, phone update, check for update. This update will bring you from current OS version 8.10.12359.845 to 8.10.12382.878. This update should be helpful to be anyone on Windows Phone 8.1. I am updating my phone and we will see is there any improvement.
