Xperia C5 Battery Issue

[Hridoypunk]

Please help me, firstly I'm sorry to you all cause my English is bad...

I brought my Sony Xperia C5bUptra Dual in 07/01/2016

My phone got some serious battery issue. 

The phone suddenly dies without any reason and when I try to open, it shows the empty battery sign. Than when I connect with charger it shows 30 or 40 % charge and charging logo (**bleep**!) the phone takes half an hour to charge 4-5% than takes only 10 minutes to reach 100%! When I start using the phone after full charge, it shut down again after few minutes using. And same thing happens. What can I do for this, in that conditions I can't take my phone outside. Is that battery problem or software?
