This keeps happening. It’s not always 15% sometimes 14% or 7% but my phone always shows 1% in the right hand corner and powers off then when connected to a charger it turns on instantly at a higher battery level
Im not certain but it sounds like your battery may just be about dead…Luckily, many Samsung phones can have their batteries easily replaced for cheap.. If your battery looks as if its swollen, that is good indicator that some of the battery cells have died
