I am running on a galaxy s4 and was thinking of upgrading to the galaxy s6 or edge as they are down in price. I was just wondering if I'm gonna be seeing the same, better, or worse battery life out of the s6. I'm a pretty light user on average days, today the phone was off the charger at around noon with 100% and is only down to 88% after checking my Facebook feed for around 10 minutes and sending some texts. Screen on time has only been about 20 minutes in the past 4 hours and as of now the phone is saying about 12 hours of usage left. What I really need to know is if the stand by time on an s6 will be as good or better than my s4. I can go to work for 10 hours and with some calls, texts and checking my social media I can come home with easily over 50% battery remaining. If I have to optimize my settings a bit to get battery life that's fine but I'd like a newer phone to get better battery than a phone that's a few years old. I've read a lot of mixed reviews, and while I know the phone performance wise and everything else is worth the upgrade I wanted to know if it will last me through a day of light to moderate usage. The only time I use my phone heavily is at home and I'm next to a charger anyways so I'm not to worried about it.
