As usual, my biggest beef is battery life. Battery is way smaller(mAh) than my GS4. I also don't appreciate that the battery is embedded and there is no microSD slot. Phone is faster than my old GS4. I like that the screen is a little bigger as well.
Love it, it lost some features the s5 has but I'm assuming that's to amp up the battery life. Love the adaptive fast charger it comes with, seriously under an hour to go from dead to fully charged, amazing. I love the wireless charging built in also and the design (smaller and thinner than the s5) Camera is great, samsung really knows how to do it! ! The quick camera comes in extremely handy, especially with the kids, they don't stay still for long! There just isn't much that I don't love about this phone!
Pros: Bright display, Built-in speakers, Durable, Lightweight, camera quality
