Well for me its been more than a month since i updated my phone
But I'm facing this battery problem from past few days
I don't understand what's wrong with my phone
I've to charge it twice a day n even if I charge it completely after some time without even using the phone battery level deducts from 100% to 90%
I don't know why after that the battery level decreases normally but first 10% just go away without being used
Please help me

Repair phone software with sony update service,if you still see problems,you may need a new battery.Anyway,take the phone into service.

It's been just 4-5 months since I brought this phone and now I need to replace the battery?

This wasn't what I expect from SONY 

anyway the SUS is again upgrading my software when it's already up to date,is this the way it repais the software?

Yes,it does not matter you are up to date,just repair phone software.Backup important things before the repairing.

I have had same experience with dropping first 10% in just few minutes after disconnecting a fully charged phone but somehow it just came back to normal discharging for 10 to 15 days...

I remember that in the same time I had problem with Sony "extension for throw" in Active Application section under settings... I've posted that experience in this forum... I'll find it so try to check that - maybe it will help you..
