Bettery Draining so fast w/o mobile and wifi connected and other issues on my Z3

[Kaizentian]

I bought my device 2 days ago, and based from my observation, my battery life doesnt last that long.. I was an iOS user before I switched to Sony.. I can tell the difference of battery life.. wherein Sony should have more battery life than iOS phones. HELP PLEASE!

It was explained to me that I need to reinstall my Lollipop 5.0.2 to fix my battery draining problem. Thank you!

Performing a system repair using PC Companion - This will factory reset your phone and erase all data

Switch off your phone and unplug from Pc (Hold volume up and power for around 10 seconds)
Start PC Companion and select Support zone then Update my phone/tablet then in Blue Repair my phone/tablet and follow the on screen instructions - When prompted connect your phone still switched off holding volume down or back button - This should start the repair or reformat process

If you are using Windows 8/8.1 or a 64bit operating system then adjust the settings for PC Companion and run in compatibility mode and chose Windows 7 or XP
