My friend began to experience
problem with his Samsung Galaxy S5. Even if it were connected to the charger it
could be charged only 10% in 2-3 hours. Sometimes it would not charge at all. He
restored and did factory reset, and this problem has disappeared. However, the
phone began to suffer extremely battery drainage and does not last more than
two hours. He recently purchased a battery from mpj and the battery life has
improved in terms of the old battery, but still terrible battery drainage. He’ll
try to flash kernel. Any advice?
