My s5 could go 2 days without a charge. My s7 lost 20% while I slept, and just browsing on Chrome causes the charge to drop like a rock. The usage graph shows like an 80 degree slope. Not sure I can live with this.
2nd day of usage here. Upgraded from an s5 and I'm very happy with everything, except battery life. If I look at this thing the wrong way it drops 20%. I've read here that battery life improves and I certainly hope it does.
