Problem is when i charge it with DC 5.0V -2.0A
it charge's fast and battery life is approximately 12 h and even without working anything and WIFI & 3G off it drops so fast..
But when i charge it with DC 5.0V -1.0A (my s4 adapter) i have battery life 50% longer..
so can anyone tell me what is your battery life in your s5 octa core or snapdragon?
if you have this problem i recommend to use s4 adapter it charge's slow but you will have large battery life.
