Sorry to hear this but you would need to either return your device to the place of purchase or contact Xperia care and have your device inspected http://www.sonymobile.com/global-en/support/contact-us/

i hace paid a visit to sony care and i have been told that for xperia zl they cannot replace its battery it has to be sent which can take approximately a week
moreover it will cost me 33% of the cost , something like that
and i must pay an amount of 144.277  USD and then my cell will be sent , reswap or replace whatever it was
i had conversation with executive of sony care sector 47-c Chandigarh India, 
Give me a good reason to spend 144.277 USD  
I can buy a new cell instead spending money.. sony care isnt capable of handling situation like this ? then wht is the point of manufaturing such faulty product?

I visited so many places(sony stores) , almost 10-20 asking for battery of my device sony xperia zl . and i wasnt able to get battery from anywhere even  Sony Care didnt had it
 Can u please advice me from whre i can buy sony xperia zl battery c6502, battery manufactured by sony the same as it comes with zl
unfortunately zl is discontunied ....
kindly advice from whre i can buy. I am from India..
 i just need an orignal genuine battery and i intend to instally it myself...i dont want to  pay 144.277  USD for one **bleep** battery...
