So I spent some time today playing with different settings on the phone and discovered a rather puzzling change to the GPS/Location settings within Kit-Kat. The passive location settings (Wi-Fi/Network) appear to be combined with the phone GPS system. Once Location is on, a shiny new icon in the quick settings menu it appears the GPS radio is also on. They removed the GPS icon and GPS control from settings. So any application that requires location data and asks you to allow location data collection is now also switching on the GPS radio and although the icon is not always visible the radio is still running in the background. GPS has always been power hungry on any phone and the Xperia was/is no different. However in previous versions of the OS I was always able to have passive location data on, and only switch GPS on when it was really needed. For those of you who have 'Hot' handsets since the upgrade, this would also be an indication the GPS radio is on. As would my problem of charging in the car cradle (Phone never charged in the cradle while GPS and walkman were running simultaneously.) I would be interested to hear from anybody who has the problem, let me know if this helps. I would also really like to hear some feedback from Sony. This is an issue I think needs to be resolved, and not just with a work around.

Not happy with the Kit-Kat update. Phone is slow and judder (Which I could almost live with) but the battery performance has dropped significently since the update. Phone will no longer charge in the car cradle, battery continues to drain at a much slower rate but it's not charging. I've checked my battery usage and it's showing Google Play Services is using 75% of my battery. What is this now doing in the background that is having such an impact on battery performance?
