I am using the phone 3a since 2 days and the battery drain faster, I’m fully charged my phone and start using and first 4 to 5 persentage gone in around 5 minutes of usage and I’m only used the gallery app, I don’t know if this is just my device issue or a software problem, does anyone else have this problem? If so please describe it, and if this is a software issue nothing should fix it.
