needed new battery for x6,nokia priority or online shoping,suggesion ??

[hskpunjabi]

my brother's x6 is behaving strange,battery is nt lasting even for 8-9 hrs...sometimes less when fully charged.sometimes battery bars are reduced to one after some time to 3-4...then again to 1.I think battery is dying. do apps like whats app can harm battery..??
Nokia care center is giving BL-5J @650 ...but flipkart/snapdeal @500(they say it is geniune)...need ur suggesion.
thanks

If you get Rs.500 at flipkart, go for it else stick with Nokia shop
