This has been happening everyday for over a week now and shows no sign of stopping.
I have heard of this problem occurring on Xperia Z devices that recently received the Kitkat update but not a word anywhere of the existence of this problem on an Xperia device running Android 4.3.
I would like to know if anyone out there is facing a similar issue while still running 4.3 on their device. And if anyone is, then have you found any solution to the problem?
Would appreciate a reply ASAP as my phone has been rendered practically useless right now with my battery going from 100% to 10% in about 6/8 hours without 3G/WiFi/GPS or anything else apart from the basic network being on.
