From two days I am facing charging problem in my Xperia M. It takes more time to charge as compare to regular days . I get charged in about 4 hours. Their is no problem with my charger it is of Xperia SP which is also mine. I am charging my M with SP charger. Does because of this this problem arise. Please tell me solution. Is this long charging time is harmful for my M or it is normal and I am unnecessary concern about it. Pls answer me
