    Currently using the .205 FW. (C5303_Vodafone_HU)
    My experiences are the following :

    1. with or without stamina ,i have the same standby time. this means max. 4.5 days. (virtually no phone usage ,good gsm coverage) 4.1.2 had averaging 14 days !
    2. no faster charging. ~150 hrs to fully charge the battery with a 850 mAh charger.
    3. Light-sensor completely usless ,although it is flawless.
    4. notification light ignores my settings. totally goes crazy.

    an so on….

    do something with this p!le 0f ***t JB 4.3. Please. 🙂

    After replacing pcb board in Sony service center am facing battery drain issue which I didn’t face previously. Firmware is up to date 12.1.A.1.205 as usual pictures captured in camera quality is very low. When I enable mobile data, phone is getting more heated, then battery drains very faster 1min 2% loss. I am frustrated of Sony due to this product and their service center (repair and return in chennai egmore).
