Sony will fix the Xperia Z, ZL, ZR and Tablet Z KitKat battery issues
For those of you that still sport a Sony Xperia Z, Xperia ZL, Xperia ZR or Tablet Z, we’re sure you’ve been quite pleased with your ability to update these legacy devices to Android 4.4 KitKat. Sony has done a great job in keeping its phones up-to-date lately, though not everything has been fun and games. Users have flooded Sony Support forums claiming that there are serious battery draining issues, and apparently there is a fix coming.
Sony has confirmed that it has detected the battery drain issues of the mentioned devices, and this problem has to do with Google Play Services. The company hasn’t provided a specific date for a fix, but it should roll-out very soon. The Sony Support forum statement reads:
We have investigated the issue with Google Play Services using a lot of battery and we have identified that the root cause of this is related to the latest version of Google Play Services (4.4.52).
Until a new version of Google Play Services is provided by Google we urge users to either uninstall the latest update of Google Play Services (might limit use of Google Services like YouTube) or go to Settings > Google (accounts) > Ads > Tick the box for Opt out of interest-based ads and also disable back up of your data by going to Settings > Backup & reset (Personal) > uncheck the box for “Back up my data”.
If you are unable to uninstall the update for Google Play Services from Settings > Apps, go to Settings -> Security -> Device administrators and disable “Android Device Manager”. Also check the settings in the Play Store so that automatic updates is not enabled as this may update Google Play Services again automatically.
