how can I fix the battery life on my vzw s5. I cannot tell what is making it die so quickly. It only lasts usually 5 to 7 hours before requiring a charge. I looked at my settings and it said the biggest battery drain was android os and I have no idea what that is supposed to mean. I have to depend on charger everyday in order to make sure it wont die on me. just today it was at I think 60% at 8 something this morning after being unplugged around 6 today. There is no reason my phone should be dying this quickly. my phone battery is so unreliable and I don't know what to do about it happened ever since I got lollipop last year. It was bad when I got lollipop last year but it seems even worse than before. I am attaching some pictures to see if anyone can figure out how to fix it. I refuse to do a factory reset because I am afraid it will be a big hassle which wont fix anything at all. Can someone please help me figure out I can make my phone last me most of the day without dying at all thanks. it drops really fast in like no time at all and I have no idea why.
