Xperia Z Battery Life

[Ramesh-Z]

My mobile battery life is gradually decreased (After installing (10.31.A.2.67 Build Number) i. e 4.2.2.)) I don’t know what happened. Please let me know what to do before this upgrade when mobile was in standby mode my mobile use to kill only 2% for whole night. However now my mobile eating more than 60% for whole n8 (may be 8hrs)

I love sony i dont want to shift from Sony to any other useless mobiles.........................................PLZZZ let me know any precautions....

How to repair my phone

With either PCC or SUS, if you have a Mac use Bridge, repair = reinstall the software/firmware

I have battery life issues since i've purchased device 2 months ago..  Battery level decreases too fast even if i am an expert user and i don't really use anything it could drain battery, maybe am i missing something else?
I work for AppleCare and i hate that **bleep** of iPhone so i would like to love this Sony Xperia Z even more!

Charge your phone 100% > use it as you normally do > once the battery is down to 50% and then to 10% 

Go to 

Settings > power management > battery > take *screenshots of

1) the whole list

2) tap on the graph and take a screenshot, it will be better on landscape

3) back to the list, tap on each of the top 3 items and take a screenshot of each

Post all the screenshots here, upload them to box.com and post the link here as sometimes the photos take few hours to appear in the forum. 

*screenshot = press and hold power & volume up at the same time.
