I have been using Samsung Galaxy Grand (I9082) since over a year and now the phone switches off randomly (generally at 28% of battery remaining) and when i try to restart manually, it does not starts (and battery drops to 1 % ) until i plug in charger and within 2 minutes battery shows more than 30% charged . I have been charging the mobile from some other nokia charger. The battery graph also shows red lines. Does this indicated the battery problem or phone.
NOTE : I have done cache cleaning with fresh Android install after the problem started in order to trying to fix the problem. Below is the battery graph.
